Easy Ranch Chicken Casserole Recipe
Ranch Chicken Casserole is the kind of cozy dinner that works when you want something creamy, cheesy, and filling without a complicated cooking process. Tender chicken, pasta, broccoli, ranch seasoning, and a creamy sauce come together in one bubbling casserole, with melted cheddar on top.

Ingredients
- 3 cups cooked, shredded chicken
- 12 ounces rotini or penne pasta
- 2 cups broccoli florets
- 1 can (10.5 ounces) condensed cream of chicken soup
- 1 cup sour cream
- 1 packet (1 ounce) ranch seasoning mix
- ½ cup chicken broth

How to Make Ranch Chicken Casserole
Step 1: Cook the Pasta and Broccoli
Preheat the oven to 375°F and lightly grease a 9-by-13-inch baking dish. Cook the pasta in salted boiling water until just shy of al dente, usually about 1 minute less than the package directions. Add the broccoli during the final 2 minutes. Drain well.
The pasta should still have a little firmness because it will continue cooking in the oven. Don’t overcook it at this stage or the casserole can become soft.
Step 2: Make the Ranch Sauce
In a large bowl, whisk together the cream of chicken soup, sour cream, ranch seasoning, chicken broth, garlic powder, and black pepper. Stir until smooth and creamy.
Fold in the shredded chicken, 1 cup of cheddar, and the drained pasta and broccoli. Mix gently so the broccoli stays in recognizable pieces and the pasta doesn’t break.
Step 3: Assemble the Casserole
Transfer the mixture into the greased baking dish and spread it into an even layer. Sprinkle the remaining ½ cup cheddar, mozzarella, and Parmesan evenly over the top. Dot the surface with the butter.
Step 4: Bake Until Bubbling
Bake uncovered at 375°F for 25–30 minutes, until the edges are bubbling and the cheese on top is fully melted with light golden spots.
For a more browned cheese topping, switch the oven to broil for about 1–2 minutes at the end, watching closely. Let the casserole rest for 5–10 minutes before serving so the creamy filling settles slightly.
Cooking Tips
- Cook the pasta slightly underdone so it doesn’t become mushy during baking.
- Drain the broccoli and pasta thoroughly; excess water can thin the creamy sauce.
- Rotisserie chicken is a convenient shortcut and works especially well here.
- For extra vegetables, add sliced mushrooms or diced bell pepper, but keep the total amount moderate so the casserole doesn’t become watery.
- If the top browns quickly, loosely cover the dish with foil for the remaining baking time.
How to Serve
Serve the casserole warm with a simple green salad, roasted green beans, or steamed vegetables. A side of garlic bread also works nicely with the creamy sauce. For a fresh finish, sprinkle chopped parsley over individual portions just before serving.
Storage and Reheating
Refrigerate leftovers in an airtight container for up to 4 days. Reheat individual portions in the microwave until steaming hot, or cover the casserole with foil and warm it in a 350°F oven until heated through. If the casserole seems dry after refrigeration, add a small splash of chicken broth before reheating. For best texture, avoid repeatedly reheating the entire casserole.
Final Result
The finished Ranch Chicken Casserole should be creamy without being soupy, with tender chicken and pasta, crisp-tender broccoli, and a golden layer of melted cheese. The ranch seasoning adds a savory, tangy flavor throughout, while the cheddar and Parmesan give the top a rich, satisfying finish.
