Chicken Broccoli Alfredo Casserole
Equipment
- 1 9x13 casserole dish
Ingredients
- 12 ounces bow tie pasta (farfalle pasta)
- 3 cups cooked chicken diced or shredded
- 4 cups broccoli florets
- 15 ounce jar Alfredo sauce
- 1 cup sour cream
- 1 teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon black pepper
- 2 cups shredded pepper Jack cheese divided
- ½ cup grated Parmesan cheese
Instructions
- Preheat the oven to 350°F. Spray a 9x13-inch baking dish with nonstick spray.
- Cook the bow tie pasta according to package directions until just al dente. During the last 2 minutes of cooking, add the broccoli florets to the pasta water. Save 1 cup of pasta water. Drain well and return to the pot.
- Stir in the chicken, Alfredo sauce, sour cream, garlic powder, onion powder, black pepper, 1½ cups shredded cheese, and grated Parmesan cheese. Add pasta water as needed - I used about ¼ cup. You want the casserole to be saucy, not dry!
- Transfer the mixture to the prepared baking dish. Sprinkle the remaining ½ cup shredded pepper jack cheese over the top. Cover with foil and bake for 25 minutes.
- Remove the foil and bake an additional 10-15 minutes until hot and bubbly.
- Let rest for 5 minutes before serving.

Frequently asked questions (FAQ's)
Yes! Assemble the casserole up to 24 hours in advance, cover tightly, and refrigerate. When you're ready to bake, let it sit at room temperature for about 20 minutes while the oven preheats, then bake as directed. You may need to add 5 to 10 minutes to the baking time.
Absolutely. Frozen broccoli is a great shortcut. Thaw it first and pat it dry with paper towels to remove excess moisture so the casserole stays creamy instead of watery.
Rotisserie chicken is my favorite because it's quick and flavorful. Leftover grilled chicken, baked chicken breasts, or poached chicken all work just as well.
Cover the casserole with foil for the first part of baking to help lock in moisture. If you're reheating leftovers, stir in a splash of milk before warming to bring back the creamy texture.
Deb's top tip
Salt the water well and don't overcook the pasta! Boil it just until al dente since it will continue cooking in the oven. That little trick keeps the bow tie pasta tender with just the right amount of bite instead of turning mushy.
Test kitchen notes
When I was testing this recipe, I found that cooking the bow tie pasta just shy of al dente gave the casserole the best texture after baking. I also discovered that adding the broccoli to the pasta water during the last couple of minutes was an easy shortcut that cooked it just right without an extra pot to wash.
One final change that really paid off was using freshly shredded mozzarella instead of pre-shredded. It melted into the Alfredo sauce much more smoothly, making the casserole extra creamy and cheesy.
