  • 1 pound cavatappi, ritoni or penne pasta
  • 3 cups broccoli, cut into bite size pieces
  • 1 pound bacon, cooked and crumbled (see notes for baking)
  • 2 tablespoon olive oil
  • 2 tablespoons unsalted butter
  • 1/2 onion, diced (or ½ teaspoon onion powder)
  • 1 red bell pepper, chopped (optional)
  • 3-4 garlic cloves, minced
  • 1/3 cup all-purpose flour
  • 3 cups half and half (may sub milk whisked with 1 ½ TBS cornstarch)
  • 2 cups low sodium chicken broth
  • 1 (1 oz.) packet dry ranch dressing seasoning mix (2 tablespoons) or use DIY below
  • 1 tsp EACH salt, dried basil, ground mustard
  • 1/2 teaspoon pepper
  • 1/4 teaspoon red pepper flakes
  • 1/2 cup sour cream (optional for extra creamy)
  • 2 cups freshly shredded sharp cheddar cheese, divided
  • 1 cup freshly shredded mozzarella cheese
  • 2 ½ cups shredded rotisserie chicken

DIY Ranch Seasoning (Optional)

  • 1 tablespoon dried parsley
  • 2 tsp EACH dried dill, dried chives
  • 1 tsp EACH onion powder, garlic powder
  • 1/4 tsp EACH pepper, salt


  • Preheat oven to 350 degrees F. Lightly spray a 9x13 baking dish with nonstick cooking spray; set aside.
  • Bring a large pot of generously salted water to a boil. Add broccoli and cook 3-5 minutes, depending on how tender you like your broccoli. Using a slotted spoon or sieve, remove the broccoli and rinse with very cold water. Strain and remove to a plate. In the same pot, proceed to cook pasta al dente according to package directions (don't overcook because it's going in the oven).
  • Melt 2 tablespoons butter with 2 tablespoons olive oil in a large saucepan. Add onions and sauté for 4 minutes. Add bell peppers and garlic and sauté an additional 2-3 minutes, until onions are soft.
  • Sprinkle in the flour and cook, while stirring, for 2 minutes.
  • Turn heat to low then gradually whisk in half and half, chicken broth and all of the seasoning. Bring to a simmer, whisking constantly. Continue to simmer over medium heat, whisking often until thickened (but not overly thick), 5-10 minutes.
  • Turn heat to low and whisk in 1 cup shredded cheddar until melted followed by 1 cup shredded mozzarella until melted. Whisk in sour cream until blended.
  • Stir in chicken, broccoli and half of the bacon until evenly coated, followed by pasta (Note: If your skillet is too small, combine everything together in a large pot like the one you cooked the pasta in.)


  • Taste and season with salt, pepper or cayenne pepper to taste. Serve from the skillet (top with remaining bacon) or proceed to assemble and bake:
  • Pour the pasta into the prepared baking dish and spread into an even layer. Sprinkle with 1 cup remaining freshly shredded cheddar.
  • Bake uncovered at 350 degrees F for 15 minutes, then remove from the oven and sprinkle remaining bacon over top. Return to the oven and bake 5 to 10 additional minutes, until the casserole is hot and bubbly. Let stand for 5 minutes, then serve.



tips and tricks

  • Ranch seasoning mix: You should NOT prepare the ranch dressing as instructed on the side of the seasoning packet. It gets added to the cheese sauce like any other dry herb or spice blend.  You can add more or less ranch mix depending on strong you would like the flavor.
  • Half and half: To make your own, combine 1 ½ cups milk and 1 ½ cups heavy cream
  • Flour: You may substitute with gluten-free flour, like Bob’s Red Mill Gluten Free Baking Flour.
  • Sour cream: You can use an equal amount of full-fat plain Greek yogurt.  You can also get away with nonfat Greek yogurt but it may separate slightly when baked.
  • Thin sauce if needed. The cheesy ranch sauce can become too thick if it’s simmered at too high of heat or for too long. But don’t worry, it’s SO easy to fix! Simply stir in a little milk or chicken broth until it reaches desired consistency. It is important that the sauce isn't too thick if you are making the casserole for meal prep because it will thicken further in the fridge.
  • To cook bacon in the oven: Line a rimmed baking sheet with foil then line bacon down the center.  Fold up the foil around the bacon so the grease won’t slide away. Bake at 400 degrees for about 20 minutes or until crispy; for thick cut bacon, bake it closer to 30 minutes or until crispy.
  • To halve the recipe: Use the sliding scale next to the servings in the recipe card and bake in an 8×8-inch casserole dish.  

Meal Prep

You can make and assemble the casserole a day in advance and refrigerate (without baking), then just pop it in the oven when it’s dinner time!  To Meal Prep:
1. Take care that your noodles are cooked al dente and are rinsed in cold water so they don’t keep cooking.  Take care the ranch sauce isn’t too thick as it will thicken more while sitting in the refrigerator.
3. Assemble the casserole according to directions up until baking.
4. Tightly cover with foil and refrigerate.
5. Let sit at room temperature for 30 minutes before baking.
6. Bake according to directions or until completely warmed through.

How to store and reheat

  • To store: Store tightly covered in the refrigerator for up to 5 days.
  • To reheat: Microwave for 1 minute then at 20-second intervals until warmed through or heat in the oven a 350 degrees F for 15 to 20 minutes, or until bubbly.
  • To freeze: Freeze unbaked by wrapping the casserole dish all the way around with two layers of plastic wrap followed by one layer of aluminum foil.  Freeze for up to 3 months.  Do NOT thaw before baking.  To bake from frozen, remove plastic wrap and cover tightly with foil. Bake at 350 degrees F for 1 hour, uncover and bake for an additional 10-15 minutes, or until hot in the center.
