1 (10.5 ounce) can cream of chicken soup: Forms the rich, creamy base of the sauce that brings everything together.

How to Make Chicken Penne Casserole Recipe

Step 1: Prep and boil pasta with vegetables

Start by preheating your oven to 375°F and positioning the rack toward the upper third. Boil a large, salted pot of water and cook the penne pasta for about 2 minutes less than the package recommends—this keeps it perfectly al dente after baking. With just a couple of minutes left on the pasta, toss in the fresh broccoli florets so they soften slightly but retain their vibrant color and crunch. Drain everything thoroughly and transfer this hot mixture into a 9x13 casserole dish, giving you a warm bed for the creamy goodness to come.

Step 2: Make the creamy sauce

In a medium bowl, whisk together the cream of chicken soup, milk, sour cream, grated parmesan, Italian dressing mix, onion powder, and minced garlic until you get a smooth, well-blended sauce. This mixture forms the heart of your casserole—creamy, slightly tangy, and filled with those signature Italian herbs that make the dish pop with flavor.

Step 3: Combine chicken, veggies, and sauce

Add the shredded cooked chicken and frozen mixed vegetables right into the casserole dish with the pasta and broccoli. Pour the luscious sauce on top and use a spoon or spatula to toss everything thoroughly until each piece is lovingly coated. This step ensures each bite delivers a harmony of tender chicken, veggies, pasta, and that irresistible sauce.

Step 4: Top with cheese and bake

Smooth the casserole out into an even layer so it cooks uniformly, then cover with a generous blanket of shredded mozzarella cheese. Pop it into the oven uncovered and bake for 20-25 minutes until it's bubbling hot and the cheese has melted into a gooey, scrumptious layer. For an extra touch, switch your oven to broil for just a few minutes to get a beautiful golden-brown crust—just keep a close eye on it to prevent burning.

In a white rectangular baking dish with light blue handles, the bottom layer consists of light yellow penne pasta mixed with bright green broccoli florets scattered throughout. On top of this pasta and broccoli layer, there is a pile of shredded white chicken placed mostly on one side. Small diced mixed vegetables in orange, yellow, green, and white colors are sprinkled around and over the chicken and broccoli, adding a pop of color. In the second image, a thick, light cream-colored sauce covers the shredded chicken and some of the vegetables, spreading unevenly across the top while still allowing parts of the pasta and broccoli to be visible around the edges. The dish sits on a white marbled textured surface. Photo taken with an iphone --ar 4:5 --v 7

Garnishes

Fresh herbs such as chopped parsley or basil sprinkled right on top add a burst of color and a fresh herbal note that cuts through the creamy richness. A light drizzle of extra virgin olive oil or a sprinkle of crushed red pepper flakes can also elevate the dish with brightness or mild heat, turning simple into spectacular.

Side Dishes

This casserole pairs beautifully with light, crisp sides like a fresh garden salad or garlic-roasted asparagus. The contrast between the creamy casserole and the crunchy veggies creates a delightful balance. Garlic bread or a warm, crusty baguette also complement the meal perfectly by soaking up any leftover sauce and adding a satisfying crunch.

Creative Ways to Present

Serve this Chicken Penne Casserole Recipe in individual ramekins or mini cast iron skillets for a charming, personal touch at the dinner table. You can also layer it with extra veggies, like sun-dried tomatoes or roasted red peppers, to add pops of flavor and gorgeous color that make the presentation as delightful as the taste.

Make Ahead and Storage

Storing Leftovers

Leftover casserole should be cooled to room temperature before storing in an airtight container. It will keep well in the fridge for up to 3-4 days, giving you plenty of tasty lunches or easy dinners to enjoy during the week.

Freezing

This Chicken Penne Casserole Recipe freezes like a dream. Simply assemble the casserole but don’t bake it; cover tightly with foil and freeze for up to 3 months. When you’re ready to enjoy, thaw overnight in the fridge and bake according to the instructions, adding a few extra minutes if needed.

Reheating

For best results, reheat portions in the oven at 350°F until warmed through and bubbly. If you’re in a hurry, the microwave works too—cover with a microwave-safe lid and heat in short intervals, stirring gently to evenly warm the casserole without drying it out.

FAQs

Can I use a different pasta instead of penne?

Absolutely! While penne works wonderfully because of its shape and texture, you can swap in rigatoni, rotini, or even elbow macaroni. Just keep in mind that cooking times might vary slightly depending on the pasta’s thickness.

Is rotisserie chicken the best option?

Rotisserie chicken is a convenient, flavorful choice that saves time, but any cooked chicken works well here—leftover roast chicken, baked chicken breasts, or even shredded turkey in a pinch.

Can I make this casserole vegetarian?

Definitely! Simply omit the chicken and add extra veggies like mushrooms, zucchini, or spinach. You can also use a vegetarian cream soup alternative or homemade sauce to keep it creamy and delicious.

What if I don’t have cream of chicken soup?

You can easily substitute with cream of mushroom or a homemade béchamel sauce for a similarly creamy texture. Just adjust seasonings accordingly to complement the flavors in the casserole.

Can I add extra cheese?

Yes! More cheese means more melty, gooey goodness, which is never a bad thing. Mix some cheddar, provolone, or even a bit of gouda for a richer, more complex flavor profile.
