Why you’ll love it

On busy days, nothing hits the spot more than a piping hot chicken casserole. There’s plenty of the creamy sauce to smother the pasta in this meal, and there’s just 10 minutes of prep. There’s broccoli in each bite, and everyone knows how tasty it is with cheese!

This simple chicken pasta bake is creamy, homestyle deliciousness. There’s no guilt in using a can of condensed soup and a packet of dressing mix every now and then! They’re both tasty and convenient, much like using rotisserie chicken is in this weeknight dinner.

What you’ll need

  • Penne – a different shape of pasta such as rotini will work fine as well
  • Broccoli – I prefer fresh, but I have tips below for frozen
  • Cream of chicken soup – a tried and true shortcut
  • Milk and sour cream – for the creamy sauce
  • Parmesan – grate your own for best flavor and meltability
  • Italian dressing mix – I like Good Seasons Zesty Italian
  • Onion powder and garlic cloves – aromatic goodness
  • Rotisserie chicken – for less hassle
  • Frozen mixed vegetables – typically it includes green beans, carrots, peas, and corn
  • Mozzarella – the final cheesy touch

Pro tip

The broccoli and veggies are tender-crisp in this recipe. You can definitely cook them for a bit longer if needed, though! There’s more info in the notes section of the recipe card.

Substitutions and variations

  • You could use cream of mushroom soup instead.
  • This recipe is pretty flexible, so instead of using the Italian dressing mix, feel free to change it up with Italian seasoning and/or your fave herbs and spices.
  • Any kind of cooked chicken will work fine. You can chop it instead of shredding it if you prefer. Try leftovers of my Air Fryer Chicken Breast or Baked Chicken Breast.

Leftovers and storage

  • Store leftovers of this chicken pasta bake for 3-4 days in the fridge.
  • Reheat slowly over a low heat in a saucepan or in intervals in the microwave. Add a splash of milk or water if it’s looking dry.
  • I don’t recommend freezing leftovers; the texture may change due to the dairy, and cooked pasta can get mushy.

Chicken Penne Casserole

This chicken penne casserole recipe combines a few pantry and freezer ingredients to make a cozy, flavorful meal! It's cheesy and an easy way to get your vegetables in.
Prep: 10 minutes
Cook: 40 minutes
Total: 50 minutes
Servings: 6

Ingredients 

  • 8 ounces uncooked penne
  • 4 cups broccoli florets see note
  • 1 (10.5 ounce) can cream of chicken soup
  • 1 cup milk I use 2%
  • 1/2 cup sour cream
  • 1/2 cup freshly grated parmesan cheese
  • 1 packet Italian dressing mix
  • 1/2 teaspoon onion powder
  • 4 cloves garlic minced
  • 2 cups shredded cooked/rotisserie chicken
  • 1 cup frozen mixed vegetables see note
  • 2 cups mozzarella shredded
  • Salt & pepper to taste

Instructions 

  • Preheat your oven to 375F and move the rack to the top third of the oven.
  • Boil a large, salted pot of water for the pasta, and cook it for 2 minutes less than the package directions indicate. Add the broccoli to the pot 2 minutes before the pasta is done (I cook the penne for 8 min and add the broccoli in at the 6 min mark). Drain and transfer to a 9×13 casserole dish.
  • To a medium bowl, add the cream of chicken soup, milk, sour cream, parmesan, Italian dressing mix, onion powder, and garlic, and stir until smooth.
  • Add the chicken and frozen mixed vegetables to the casserole dish, and then pour the sauce mixture over top. Toss until everything is well coated.
  • Smooth it out in an even layer, and then top it with the mozzarella.
  • Bake, uncovered, for 20-25 minutes until hot and bubbly. Optional: broil it for a few minutes to brown the cheese (watch it closely so it doesn't burn). Season with salt & pepper as needed.

Notes

  • 1 pound of broccoli typically makes  about 3-4 cups when cut into florets. A little more or a little less than suggested won’t make or break this recipe!
  • For frozen broccoli: add it from frozen to the boiling water with the pasta, but only cook it for up to a minute since frozen broccoli is already par-cooked and you don’t want it getting too soft in the oven.
  • I recommend letting the frozen mixed veggies thaw on your counter for 15 min or so prior to starting the recipe. The veggies end up tender-crisp in this recipe. If you want them super soft, throw them in the water at the same time as the broccoli.
