Pepper (½ tsp): Adds mild heat and complexity.

How to Make Chicken Pesto Pasta Bake Recipe

Step 1: Preheat and Prepare the Squash

Start by preheating your oven to 350 degrees F. This temperature is perfect to roast the summer squash gently until tender. Cut the squash into cubes, place them in your casserole dish, and drizzle with avocado oil. Roasting the squash for 15 to 20 minutes encourages caramelization, which brings out its natural sweetness and creates a lovely texture that contrasts beautifully with the creamy pasta.

Step 2: Cook the Pasta

While the squash softens, cook your penne pasta according to the package instructions. Make sure to drain it well after cooking to avoid sogginess in your bake. The penne’s hollow shape is fantastic for catching the luscious pesto and yogurt sauce, ensuring every bite is bursting with flavor.

Step 3: Whisk the Yogurt Sauce

In a small bowl, whisk together the plain yogurt, garlic powder, salt, pepper, and one tablespoon of warm water until smooth. This mixture adds a subtle tanginess and creaminess that complements the pesto, balancing the rich and fresh flavors harmoniously.

Step 4: Combine Pasta, Sauce, and Pesto

Pour the yogurt mixture alongside the spinach basil pesto into the drained pasta and stir well. This creates a vibrant and creamy coating that ties every ingredient in your Chicken Pesto Pasta Bake Recipe together with flair and deliciousness.

Step 5: Layer the Casserole

Now mix the roasted summer squash, cooked chicken, and halved grape tomatoes directly into the casserole dish. Then fold in the pesto-coated pasta until everything is evenly combined, ensuring each serving has a perfect balance of chicken, veggies, and pasta.

Step 6: Top and Bake

Sprinkle shredded mozzarella generously over the top and, if desired, finish with crushed walnuts for added texture. Bake your dish for about 20 minutes, until the cheese melts into a golden, bubbly delight and everything is heated through. The aroma filling your kitchen at this point is pure comfort food bliss.

Make Ahead and Storage

Storing Leftovers

You can keep any leftovers from your Chicken Pesto Pasta Bake Recipe in an airtight container in the refrigerator for up to three days. This makes for a convenient and delicious lunch or dinner option that tastes just as good the next day.

Freezing

This recipe freezes exceptionally well. Portion the bake into freezer-safe containers before baking or after cooling, and store for up to two months. When you’re ready, thaw overnight in the fridge for an easy and satisfying meal anytime.

FAQs

Can I use a different type of pasta for this recipe?

Absolutely! While penne works great for holding the sauce, rigatoni, fusilli, or even farfalle can all be swapped in without sacrificing texture or flavor.

Is it possible to make this Chicken Pesto Pasta Bake Recipe vegetarian?

Yes! Simply omit the chicken and consider adding extra vegetables like mushrooms, zucchini, or artichokes to keep the dish hearty and delicious.

Can I substitute store-bought pesto?

You certainly can. A good quality store-bought pesto will save time and still lend that fresh herb flavor core to the dish, though homemade always feels extra special.

What can I use instead of plain yogurt?

Greek yogurt or sour cream are excellent alternatives if you want a thicker texture or slightly different tang, just adjust the seasoning to your liking.

How do I make this recipe nut-free?

Simply skip the crushed walnuts on top. The bake is delicious and satisfying without them, and you’ll still enjoy plenty of crunch from the roasted squash.
