Ingredients You’ll Need

• 1.5 lbs boneless, skinless chicken breasts, cubed: for lean, quick-cooking protein.
• 12 oz short pasta like penne or rotini: holds the sauce beautifully.
• 1 cup basil pesto (store-bought is fine!): brings that herby, garlicky punch.
• 1 cup Greek yogurt or light sour cream: creates a creamy, tangy base without being too heavy.
• 1 (10.5 oz) can condensed cream of chicken soup: the secret to a rich, cohesive sauce.
• 1 cup shredded mozzarella cheese: for that iconic stretchy, melty top.
• 1/2 cup grated Parmesan cheese: adds a salty, nutty depth of flavor.
• 1 teaspoon garlic powder: a little extra garlic never hurt anybody.
• 1/2 teaspoon each of salt and black pepper: to season everything perfectly.
• Optional: 1 cup halved cherry tomatoes or a handful of fresh spinach for a pop of color and veggie boost.

Let’s Get Cooking Step by Step

1. First, preheat your oven to 375°F (190°C) and grab a 9×13 inch baking dish. No need to grease it—the saucy goodness will take care of that.
2. Cook your pasta according to the package directions, but aim for al dente. It’s going to keep cooking in the oven, so you want it to have a little bite. Drain it well and set it aside.
3. While the pasta cooks, let’s make the magic sauce. In a large bowl, mix together the pesto, Greek yogurt (or sour cream), condensed soup, garlic powder, salt, and pepper. Stir it until it’s smooth and combined.
4. Add the uncooked, cubed chicken and the drained pasta to the bowl with the sauce. Gently toss everything together until the chicken and pasta are evenly coated. If you’re using tomatoes or spinach, fold them in now.
5. Pour the whole mixture into your baking dish and spread it out into an even layer. Seriously, that’s it for the hard part.
6. Sprinkle the mozzarella and Parmesan cheeses evenly over the top. This is what creates that gorgeous, golden crust we’re all here for.
7. Bake for 35-45 minutes, or until the cheese is melted and bubbly, and the chicken is cooked through (you can check by cutting into a larger piece—no pink should remain). Let it rest for about 5 minutes before serving. So good.

Healthy Options For Cheesy Pesto Chicken

Want to lighten things up a bit? You’ve got options. For a boost of protein and less fat, using Greek yogurt is a fantastic start. You can also swap the regular pasta for a whole wheat, chickpea, or lentil variety to add fiber. To pack in more veggies, stir in some chopped broccoli florets or zucchini slices along with the chicken. And honestly, if you’re watching sodium, look for a low-sodium cream of chicken soup and a pesto with less salt. It’s all about making it work for you and your healthy dinner goals.

Serving Suggestions For Your Casserole

This casserole is a hearty meal all on its own, but I love rounding it out with a simple side. A crisp green salad with a light vinaigrette cuts through the richness perfectly. For something a bit heartier, some roasted asparagus or garlic green beans are wonderful. And you can’t go wrong with a simple slice of crusty bread to sop up every last bit of that cheesy pesto sauce. It’s one of those dinner dishes that easily becomes the star of the table.

Variations & Substitutions

Don’t be afraid to make this recipe your own! Out of chicken? A can of drained and rinsed cannellini beans or some leftover turkey are great substitutes. For a different flavor profile, try using sun-dried tomato pesto instead of basil. If you’re dairy-free, nutritional yeast can stand in for the Parmesan, and your favorite vegan cheese and cream soup alternative will work beautifully. Feeling a little spicy? Add a pinch of red pepper flakes to the sauce. The beauty of a casserole is its flexibility for cheap dinners for a family.

Storage & Reheating

Leftovers? They might be even better the next day! Let the casserole cool completely, then store it in an airtight container in the fridge for up to 3 days. To reheat, the oven is your best friend for keeping that crispy cheese topping. Pop individual portions in a 350°F oven for 15-20 minutes, or until heated through. You can microwave it, but the cheese topping will soften. To freeze, wrap the cooled casserole tightly and freeze for up to 3 months. Thaw in the fridge overnight before reheating.

Frequently Asked Questions

Q: Can I assemble this Cheesy Pesto Chicken Casserole ahead of time?
A: Absolutely! Assemble the casserole right up to the point of baking, cover it tightly, and refrigerate for up to 24 hours. You might just need to add a few extra minutes to the baking time since it will be going into the oven cold. It’s a lifesaver for easy meals.

Q: My family isn’t a fan of pesto. Can I use something else?
A: Of course! A good marinara sauce or a creamy Alfredo sauce would be delicious alternatives. The method stays the same—just swap the pesto for about a cup of your preferred sauce. It’s all about finding those quick dinner ideas that work for your crew.

Q: Is the chicken cooked before adding it to the casserole?
A: Nope! That’s one of the time-saving tricks here. The uncooked chicken cubes cook perfectly in the sauce as the casserole bakes, staying juicy and absorbing all the wonderful flavors. It’s what makes this one of the easiest healthy dinner recipes in my rotation.
