  • THE SAUCE.ย  The tomato cream sauce is 1000X better than traditional tomato sauce! Itโ€™s vibrant, aromatic, lightly creamy, with a subtle sweetness and slight kick of heat.
  • SHORTCUT VEGGIES.ย  A quick blitz of the onions, celery and carrots (optional) in the food processor has them chopped in seconds.ย 
  • NO DRY PASTA.ย  The pitfall of sad, dry, Baked Spaghetti Casserole is avoided by using plenty of sauce and tossing the spaghetti with the sauce before layering.
  • HIDDEN CHEESE.ย  The whole point of making Baked Spaghetti is so it can be cheesy!ย  A molten layer of mozzarella and Parmesan are hidden in the middle of the casserole and blanketed on top, then baked to golden, bubbly perfection.
  • KID AND ADULT FRIENDLY.ย  The tomato cream sauce levels up the dish, Kids love the cheesy, saucy pasta while adults love the more sophisticated, leveled up sauce infused with onions, garlic and basil.
  • CUSTOMIZABLE.ย  Make this recipe as lean or as indulgent as you wish!ย  Swap the Italian sausage for chicken sausage or turkey sausage, the heavy cream for evaporated milk or half and half, use less cheese and/or add veggies.
  • MAKE AHEAD FRIENDLY.ย  This recipe tastes even better when prepped ahead. Simply assemble, refrigerate, then bake when ready!
  • FREEZER FRIENDLY.ย  ย This recipe freezes well for no hassle busy nights, gifts for new moms or when someone has had surgery.ย  You can also double the batch and eat one casserole for dinner and freeze the other for later – double the yum without double the work!

Baked Spaghetti Recipe Ingredients

This Baked Spaghetti recipe uses pantry friendly ingredients so you can whip it up any night of the week! Just keep some sausage in the freezer and you’re golden. Letโ€™s take a closer look at what you’ll need (full recipe in the printable recipe card at the bottom of the post):ย 

  • Spaghetti: I prefer the texture of thin spaghetti, but you may use regular spaghetti if you wish.
  • Hot Italian sausage: This will not make your Baked Spaghetti taste spicy, just flavorful. Italian sausage comes seasoned with Italian seasonings, primarily fennel. Fennel is crucial for authentic Italian flavor so if you swap the sausage for chicken, beef or turkey, make sure to add some fennel and additional Italian seasonings.
  • Crushed tomatoes:ย You will need two 28 ounce cans crushed tomatoes (often called crushed tomatoes in puree). Take care your crushed tomatoes donโ€™t have any additional seasonings or added salt. I recommend high-quality San Marzano tomatoes for their sweet, intense tomatoey flavor and lower acidity. Some reputable brands include San Marzano, Cento and Muir Glen. San Marzano tomatoes are usually sold โ€œwholeโ€ so you will want to pour them into a bowl and crush them first.
  • Heavy cream: This is what transforms our “red sauce” into “cream sauce!” It creates a rich, indulgent sauce while also balancing the acidity of the tomatoes. If you need to save some calories, swap in evaporated milk or half and half.
  • Carrots and celery: Their sweetness balances the acidity and adds complex dimension of flavor. You may skip if you don’t have them on hand.
  • Onion: One yellow onion will do the trick.ย  For lazy days, substitute with onion powder.ย 
  • Garlic: I use 6-8 cloves of garlic but feel free to use less if you prefer. You may also use 1-1 ยฝ teaspoons garlic powder โ€“ but the real stuff is so much better!
  • Seasonings: This Baked Spaghetti recipe is seasoned to perfection with basil, parsley, oregano, thyme, salt, pepper and optional red pepper flakes. The red pepper flakes are for those who love heat, otherwise, simply omit them or add to individual servings.
  • Beef bouillon: This adds a depth of concentrated flavor which makes the sauce taste like itโ€™s been simmering all day. You can use beef base (such as Zoup! or Better Than Bouillon), granulated bouillon, or crushed cubes, all in equal amounts.ย  Add the bouillon directly to the pot, donโ€™t dissolve in water first.
  • Sugar: The acidity of the tomatoes is balanced with ½ teaspoon or so of sugar. The amount of sugar will depend on the actual acidity of the tomatoes, whether or not you used a carrot and personal preference.
  • Mozzarella:ย Its milky, buttery richness cuts through the tangy sauce and melts beautifully to create a blanket of ooey gooey cheese. ย Please use only freshly shredded mozzarella for superior melting ability and flavor. You can use a block of low skim mozzarella or splurge for a block of fresh mozzarella – yum!
  • Parmesan:ย This infuses the pasta casserole with alluring salty, nutty flavor. Please use freshly grated!

This Baked Spaghetti recipe is simple to prepare and is excellent for planned leftovers! Full instructions are provided in the recipe card at the end of this post, but hereโ€™s an overview of the process:ย

TIPS FOR making Easy baked Spaghetti Recipe

  • Use the right pot.ย  Use a large enameled Dutch oven for this recipe so you can easily combine the sauce and pasta in one pot. The best pots to cook tomato sauces in areย stainless steel orย enameled cast iron (like a Dutch oven).ย  Porcelain enamel is a type of glass thatโ€™s resistant to both acidic and alkaline foods.ย Donโ€™t use reactive cookware like aluminum, cast iron or nonstick pans.ย 
  • Cheese: Please buy blocks of mozzarella and Parmesan cheese and shred them yourself. The bags of pre-shredded cheeses found at the grocery store contain anti-clumping ingredients like starch, so they donโ€™t melt as beautifully as freshly grated blocks of cheese and most importantly, don’t taste as good!
  • Use fresh ingredients โ€“ or donโ€™t:ย ย Use fresh garlic, onions, basil and parsley for the ultimate sauce, or use dried/powdered substitutes when needed for a convenient pantry friendly meal.ย ย 
  • Cook pasta in salted the water.ย  Always salt your pasta water โ€“ it is the one chance you have to flavor the pasta and enhance the subtle pasta flavor โ€“ you can taste the difference.ย  Use 1 tablespoon salt for 6 quarts of water.
  • Donโ€™t overcook spaghetti. Iย recommend testing your spaghetti 2 or 3 minutes before the box recommends. The pasta should be 1 minute shy ofย al denteโ€“ meaning it should be a little firm/have a โ€œbiteโ€ because it will continue to cook in the oven.ย 
  • Stop spaghetti from continuing to cook.ย If your sauce isn’t ready to receive the spaghetti as soon as it’s drained (which is ideal), rinse it with cold waterย until the pasta is coldย to prevent it from continuing to cook.
  • Don’t miss the sauce. After you add the spaghetti to the pan, there will be some sauce left behind that wasn’t clinging to the pasta. Pour this all over the spaghetti before adding the final layer of cheese.

Variations for Baked Spaghetti

  • Use a different pasta shape: Penne, cellentani, rigatoni, tortellini, etc. would all be tasty.
  • Swap the protein. I recommend hot Italian sausage because it is mega juicy and flavorful but you can certainly swap the pork for hot Italian chicken or turkey sausage. ย You can also use plain lean ground beef, ground chicken, ground turkey, sliced sausage etc. If you go plain, but be aware you will be losing the Italian seasonings and spice, so I recommend additional Italian seasonings, a pinch of red pepper flakes and ground fennel (about ยผ teaspoon fennel).
  • Add or swap veggies. Omit the veggies and/or add different or additional veggies such as mushrooms, asparagus, broccoli, zucchini, spinach, etc.
  • Choose the spice level. Add additional red pepper flakes to kick up the heat or add them to individual servings.
  • Add cheeses. Swap some of the mozzarella for provolone or Gouda to mix up the flavor profile. You can even add a layer of cream cheese, sour cream or cottage cheese in the middle.
  • Make gluten-free. Use your favorite gluten-free pasta.

FAQs about Baked Spaghetti

Is baked spaghetti better than regular?

It’s totally personally preference or what you’re in the mood for! We love Baked Spaghetti when we’re in the mood for pure comfort food. The tomato cream sauce is utterly divine with subtle creaminess and less acidity than traditional spaghetti sauce. The baked spaghetti casserole is extra cheesy with with a hidden layer in the middle of the casserole and then generously sprinkled on top.

How do you keep baked spaghetti from drying out?

The key to preventing Baked Spaghetti from drying out is to use enough sauce and to not overbake. This recipe uses two 28 ounce cans of crushed tomatoes in puree plus heavy cream to ensure extra sauciness!

How do you know when baked spaghetti is done?

Baked Spaghetti is easy to tell when it’s done by watching the cheese. The spaghetti and the sausage are already cooked and should be warmed from the stove, so the casserole is done with the blanket of mozzarella cheese is melted on top,

Do you have to cook pasta before baking?

Yes, pasta should be cooked in boiling salted water before baking because it will not fully bake in the oven. Take care that you cook the pasta al dente, meaning it still has a little bite to it, so it’s the perfect texture (not soggy) after it’s baked.

Do I cover baked spaghetti while it bakes?

Yes, cover the spaghetti casserole while it bakes to melt the cheese, then uncover and let it bake a few more minutes to create a golden crust.

Notes

  • Sausage substitutions: Swap the pork for hot Italian chicken or turkey sausage. ย You can also use plain lean ground beef, ground chicken, or ground turkey. If you go plain, be aware you will be losing the Italian seasonings and spice, so I recommend additional Italian seasonings, a pinch of red pepper flakes and ground fennel (about ยผ teaspoon fennel).

  • To freeze:ย  Assemble the pasta bake according to recipe directions in a freezer-safe dish, but do not bake. ย ย Wrap the dish tightly all around with 2 layers of plastic wrap, followed by foil. Label and freeze for up to 3 months.ย  Bake from frozen by removing the plastic wrap and re-covering with foil.ย  Bake at 350 degrees F for 1 hour. Remove foil and bake an additional 15-30 more minutes or until the cheese is completely melted and the dish is warmed through.ย

    This recipe was amazing! Made it last night and we all loved it. Made it exactly as written, added 1 tsp sugar. I like the flavor the carrots and celery add to the sauce, but not the little chunks. I learned this tip a long time ago- peel your carrot and cut it in half lengthwise , then cut each piece into 2. cut your celery stalk into 3 chunks. Add these to the sauce for the simmer time and then pull them out like the bay leaf. Gives you the flavor without the pieces for those who might want a smoother sauce. Thank you so much for this delicious recipe. Can’t wait to eat the leftovers.

      Great tip! I’m so glad that you loved the recipe!

  2. Barbara Forshee says

    Loved this recipe. It makes a large pan full so I was wondering if it could be frozen after it has been cooked? Thanks for the advice and for all your delicious recipes!

    • Jen says

      I’m so glad you love it! Yes you can freeze it afterwards, but the texture could change. For best results thaw the frozen dish completely before reheating!
