This Crockpot Beef and Broccoli is a Classic

Beef and broccoli is the epitome of Chinese food in my book and now everyone can make it at home with this easy crockpot beef and broccoli recipe!  This recipe is a must make now recipe.  My husband declared it in his “top 10 recipes” of all time, and I couldn’t put my chopsticks down. 
This slow cooker beef and broccoli recipe is mostly dump and simmer – most of the prep is simply slicing the beef! Cooking the beef and broccoli in the slow cooker eliminates the marinade, the searing, the oil, and most of the hands-on cooking time. This means healthier and easier beef and broccoli that is melt-in-you-mouth tender and dripping with flavor. 

The epic sauce for this slow cooker beef and broccoli is based off of my readers’ favorite Beef and Broccoli stir fry with hundreds of rave reviews.  It makes this recipe.  It is rich, umami, slightly sweet, mostly savory, and 100% addictive. All of the ingredients get whisked together directly in the slow cooker, then tossed with the beef. The beef bathes in the aromatic sauce for 3-4 hours while your home fills with the seductive aroma of tender, juicy, beef and broccoli.

The slow cooker beef and broccoli sauce is also extraordinary because it’s not sad and watery like most crockpot sauces but is gorgeously glossy thick.  This stunning consistency cannot be achieved with a cornstarch slurry, so the sauce is simmered on the stove at the end of cooking while the broccoli is added to the beef. The resulting sauce is everything you want in the perfect beef and broccoli.  Of course, you are welcome to serve the sauce as is and skip the simmering if you like.
 
As far as ingredients, you should have all of the ingredients to make this slow cooker beef and broccoli recipe if you do much Asian cooking at all, and if you don’t, the ingredients are easy to find at your grocery store. So, stock up because this crockpot beef and broccoli is going to be a repeat family favorite, and maybe even one of your “top 10 recipes of all time.”

Beef and Broccoli Crockpot Ingredients

The BEST slow cooker beef and broccoli needs the best sauce!  It’s made with beef broth, oyster sauce, Japanese rice wine, brown sugar, Asian chili sauce, sesame oil, ginger, garlic and cornstarch.  Once you have everything stocked (if you don’t already), you’ll be ready to make this recipe again and again – AND all of my other Asian recipes!

  • Broccoli: fresh broccoli cut into bite size pieces.  You can also purchase a prechopped broccoli florets, but you’ll still want to chop them into uniform pieces.
  • Ginger, Onions and Garlic: this slow cooker beef and broccoli recipe relies heavily on the aromatics for flavor, which adds a warm, spicy, almost pepper taste.  Of course, use more or less to taste.
  • Beef broth:  use low sodium beef broth so you can control the salt level.  Please don’t use vegetable broth or it will leave you with sad, wanting results.
  • Oyster sauce:  is a necessity in Asian sauces and stir fry recipes.  It adds that extra punch of flavor that takeout sauces have and will elevate your crockpot beef and broccoli to new heights.  Oyster sauce is a thick, brown sauce with a balance between sweet and salty with an earthy undertone, due to the oyster extracts.  You can find oyster sauce in the Asian aisle of any supermarket for only a few dollars.  Please use QUALITY oyster sauce such as Lee Kum Kee or Kikkoman.  You truly can taste the difference and will be sorely disappointed with less quality brands.
  • Soy sauce:  use low sodium soy sauce or your beef and broccoli will be too salty.
  • Brown sugar:  adds just a little adds sweetness to balance the oyster sauce.  You may need more or less depending on personal taste. 
  • Rice wine should become a pantry staple if you do much Asian cooking.  I use it in almost all of my Asian Recipes from my Beef Bulgogi to my Mongolian Chicken and Sesame Noodles.  Rice wine is NOT rice vinegar- DO NOT switch them out.  Rice wine adds a sweetness and depth of flavor; rice vinegar, on the other hand, will add an acidic flavor.
  • Asian chili sauce: use your favorite chili sauce like Sambal Oelek or sriracha (I use Sambal Oelek with the green lid). If you feel like your slow cooker beef and broccoli beef is missing something, it is probably heat!  It elevates the beef and broccoli recipe to another dimension of deliciousness.  I recommend starting with less and adding more to taste at the end of cooking if you would like it spicier.
  • Toasted sesame oil:  a “secret ingredient” that adds an irresistible, subtle nutty flavor.
  •  Cornstarch:  helps thicken the sauce to a glossy, luscious consistency.
  • Salt and pepper: every recipe benefits from salt and pepper – they enhance the rest of the flavors.   Use more or less to taste.

Beef and Broccoli Crockpot Recipe Variations

While this beef and broccoli is just right for us, you can adjust it to make it just right for YOU and your family’s personal tastes:

  • Sweeten it up: with additional brown sugar at the end
  • Make it less sweet: by adding less sugar to the sauce 
  • Spice it up:  add additional Asian chili sauce to taste
  • For extra tang: add additional rice wine
  • Amp up the garlic and/or ginger: for a stronger punch of flavor, or use less for a milder sauce
  • Add veggies: add additional vegetables such as bell peppers, carrots, etc.
  • Add crunch: with peanuts or cashews; take care to purchase raw, unsalted nuts so your recipe isn’t too salty.  To elevate your cashews or peanuts, dry roast them in a skillet until toasted- YUM!
  • Water chestnuts:  are delightfully crunchy and easy to find at any grocery store.
  • Sesame seeds:  add a nutty sesame flavor.  Take care to use toasted sesame seeds or toast them yourself.
  • Fruit:  pineapple, Mandarin oranges or mangos add a juicy, fresh, sweet dimension. They are the sweet ying to the umami yang– just think teriyaki chicken and pineapple. If you’re intimidated by choosing or cutting mangos, check out this post here.  For the oranges, fresh oranges hold together better but canned or super convenient.

How to Make Slow Cooker Beef and Broccoli

This slow cooker beef and broccoli recipe is very simple with mostly hands of low and slow cooking.  Here’s how to make it: 

Add sauce and beef to crockpot.  Add all of the sauce ingredients to the crockpot and whisk to combine.  Make sure to whisk thoroughly until the cornstarch dissolves.  Add the beef and stir to combine.

  • Cook beef until tender.  Cover and cook on LOW for 3-4 hours, until the meat has cooked through and is very tender.

  • Thicken sauce.  The sauce will be slightly thickened after the beef is cooked but will thin once you add the broccoli.  You can choose to add the broccoli and not thicken the sauce any more, or if you prefer a luxuriously thick sauce, you’ll need to thicken it on the stove.   To do so, tilt the slow cooker to the side and ladle out as much sauce as possible into a saucepan. Simmer the sauce on the stove until quite thick.  You want it thicker than the final desired consistency because it will thin when combined with the broccoli in the slow cooker.

  • Steam broccoli. Meanwhile, add broccoli to the top of the beef in the crockpot and cover (don’t stir it in, we want the broccoli to steam).  Cook for 20-30 minutes longer, or until broccoli reaches desired crisp-tenderness.

Beef and Broccoli Crockpot Recipe Tips and Tricks

This slow cooker beef and broccoli recipe is pretty straightforward, but here is a summary of some tips and tricks to make it a sizzling success:

  • Use a sharp knife. Sharpen your knife before slicing the steak to ensure buttery clean cuts.
  • Freeze steak.   Place your steak in the freezer 30 minutes before cutting. This will help it not wiggle beneath your knife so it’s much easier to slice thinly and cleanly.
  • Slice steak into thirds.  I recommend slicing your steak into thirds before you freeze it so you can work with one third at a time while the rest of the steak stays frozen.
  • Slice steak across the grain.  You want to cut perpendicular to the muscle fibers running through the steak in one direction so they become as short as possible and virtually undiscernible.  If you cut with the grain, the fibers are left long which results in chewy, rubbery steak. 
  • Slice steak thinly.  This goes with slicing your steak across the grain – by slicing your steak thinly (about 1/8-inch slices or less), you are shortening the muscle fibers which results in more tender steak.
  • Use quality ingredients. QUALITY oyster sauce like Lee Kum Kee or Kikkoman is essential because you can TASTE the difference!
  • Garlic pro tip.   Purchase the pre-bagged, already peeled garlic to save time.  They are actually less expensive than whole garlic cloves (at least when I did the math).
  • Garlic substitute.  Use more or less garlic depending on your garlic love.  You may substitute the fresh garlic with 1 ¼ teaspoons garlic powder whisked directly into the sauce.   
  • Ginger substitute.  Adds a warm spicy, almost pepper taste.  You may substitute the fresh ginger with 1 teaspoon ginger powder whisked directly into the sauce.
  • Ginger pro tip.  I like to freeze ginger so it’s always at my fingertips.  To freeze ginger: grate it, spread it by the teaspoon or tablespoon on parchment paper and flash freeze until solid, about 1 hour.  Transfer to an airtight container or plastic bag for up to 6 months.   You can add frozen ginger directly to your stir fry.   You can also grate frozen garlic if you have a quality microplaner.
  • Swap veggies.  You can substitute the broccoli with your other favorite veggies or you can swap some of the broccoli with other veggies. 
  • Use rice wine and NOT rice wine vinegar.  Rice wine is NOT rice vinegar- DO NOT switch them out.  Rice wine adds a sweetness and depth of flavor; rice vinegar, on the other hand, will add an acidic flavor.
  • Add heat.  Customize the heat with additional sriracha or chili sauce.  If the beef and broccoli feels like it’s missing something, it is probably heat.
  • Don’t overcook broccoli.  Take care not to over-cook the broccoli.  It should be crisp-tender like in a stir fry and not tender-crisp.

How to make the beef extra tender

Successful slow cooker beef and broccoli depends on melt-in-your-mouth beef. Here’s how to make your beef extra tender:

  • Use the correct beef. As previously discussed, avoid super lean, tough cuts of steak such as flank steak or skirt steak. Top sirloin will deliver tender beef and broccoli every time.
  • Slice the beef THINLY across the grain.  The beef doesn’t have to be razor thin like Beef Bulgogi, but should be as thin as you can get it. Aim for 1/8-inch thick or thinner.   Thin slices help the steak cook more quickly, and emerge buttery tender, seeping with flavor.  It is much easier to thinly slice your steak if you freeze it for 30 minutes or so. 
  • Slice your beef across the grain.  You also want to take care to slice the beef ACROSS the grain.  You can see the “grain” running through the meat in one direction. The grain is essentially the muscle fibers running through the meat.  You want to cut perpendicular to the muscle fibers so they become as short as possible.  If you cut it parallel to the grain you will end up with long muscle fibers which make your steak chewier.
  • Cook crockpot beef and broccoli on low. Cooking the beef low and slow provides enough time for the protein fibers to break down which results in tender beef. High heat will essentially boil the beef which is always a big no-no because it dries out your the beef.
  • Cook beef for long enough. If you’ve followed all the aforementioned steps and your beef isn’t as tender as you like, it just needs more cooking time. Even 30 minutes can make a huge difference, so be patient, and cook on!

What to Serve with Slow Cooker Beef and Broccoli

Traditionally, beef and broccoli is served with rice to soak up all the sauce and for a neutral textural component because sauce is SO flavorful.

RICE OPTIONS

  • Rice. You can pile your beef and broccoli on white rice (I recommend jasmine), or brown rice.  You can also use microwave rice pouches if you’re making a serving for one or meal prep.  
  • Low carb.  Cauliflower rice, quinoa or a blend of brown rice and any of the aforementioned options.  You can also serve the beef and broccoli in lettuce wraps. 
  • Noodles.  Ramen, soba noodles, rice noodles or even linguine are a fun way to mix things up! You can also use low carb noodles such as zoodles or spaghetti squash.

Notes

Tips and Tricks

  • Slice steak thinly.  Place the steak in the freezer 30 minutes before cutting. This will help you cut it thinly. 
  • Oyster sauce substitute. If you’re allergic to shellfish, use LEE KUM KEE Vegetarian Stir-Fry Sauce instead of oyster sauce.
  • Use rice wine and NOT rice wine vinegar.  Rice wine is NOT rice vinegar– DO NOT switch them out.  I use “Kikkoman Aji-Mirin: Sweet Cooking Rice Seasoning” which is commonly found in the Asian section of most grocery stores or you can Amazon it.  I highly suggest you google image before you head off to the grocery store so you know exactly what you are looking for.  The best substitute for rice wine is pale dry sherry.
  • Use quality ingredients. Use QUALITY oyster sauce like Lee Kum Kee or Kikkoman is essential because you can TASTE the difference!
  • Steamed broccoli.  Instead of adding broccoli directly to the crockpot, you can add the broccoli to a microwave safe bowl. Fill the bowl with water to about 1/8-inch up the sides. Cover and microwave on high for 2-3 minutes or until the broccoli is crisp-tender.
  • Swap veggies.  You can substitute the broccoli with your other favorite veggies or you can swap some of the broccoli with other veggies.  Most vegetables, aside from carrots) will only need 20-30 minutes in the crockpot. 
  • Simmering the sauce is optional.   The sauce will be slightly thickened after the beef is cooked but will thin once you add the broccoli.  You can choose to add the broccoli and not thicken the sauce any more on the stove, or if you prefer a luxuriously thick sauce, you’ll need to thicken it on the stove.  
  • Don’t overcook broccoli.  Take care not to over-cook the broccoli.  It should be crisp-tender like in a stir fry and not tender-crisp.   
  • Cook beef for long enough. If your beef isn’t super tender, it just needs more cooking time. Even 30 minutes can make a huge difference, so be patient, and cook on!

HOW TO STORE AND REHEAT 

This crockpot beef and broccoli reheats wonderfully for lunches or dinners, just take care to not overcook the broccoli initially.
  • How to store:  store leftovers in an airtight container in the refrigerator for up to 5 days.
  • How to reheat in microwave: transfer small portions to a microwave safe dish, heat for one minute, stir then continue to heat at 30 second intervals.
  • How to reheat on the stove: for larger portions, rewarm gently in a large skillet, stirring often.

    Do you happen to have the nutritional information numbers on this dish? Thanks in advance.

  2. Colleen says

    This was so good! I only used 1 tsp Sambal (I’m a spice wimp), reduced the amount of broccoli then added water chestnuts and baby corn. This will be a regular dish in our house. Thank you!

    • Jen says

      Nothing wrong with that! I’m so glad that it was a hit!

  3. Casie says

    Can I use flank steak in this slow cook recipe?

    • Jen says

      Hi Casie, you can use it but it won’t be quite as melty tender.

  4. Olivia says

    I’ve never left a review of a recipe because I’m just not that good at cooking so they don’t usually turn out as good as I hope- BUT. This was so easy and tasted delicious! Even my picky toddler ate it! Definitely recommend trying!

    • Jen says

      Yay! I am so thrilled this was a success! Thanks for taking the time to let me know how it went!

  5. Tammy says

    Hi I can’t do spicy. Is there a substitute I could use for the chili sauce?
    Your recipes are fantastic!

    • Jen says

      Hi Tammy! If you don’t do spicy, then you can just omit the chili sauce. There are ways to lessen the heat of the sauce, adding a little sugar, acid, water or fat from dairy or even peanut butter and I know that there are sweeter chili sauces that are more sweet than spicy but I have not tried those tweaks with this particular recipe. I hope that you love this recipe!

  6. Peggy O says

    My grandson is allergic to sesame. Is there a substitute?

    • Jen says

      Hi Peggy! You can use peanut oil or sunflower oil. Light olive oil has a more neutral flavor but could still work if you don’t have those oils. I hope your grandson loves it!
