Ingredients
- 1 pound penne pasta (or your favorite short pasta)
- 2 boneless, skinless chicken breasts, cubed
- 1 cup basil pesto (store-bought or homemade)
- 1 cup heavy cream
- 1 cup chicken broth
- 2 cups shredded mozzarella cheese, divided
- 1/2 cup grated Parmesan cheese
- 1 small onion, finely chopped
- 3 cloves garlic, minced
- 2 tablespoons olive oil
- 1 teaspoon Italian seasoning
- Salt and black pepper to taste
- Fresh basil leaves for garnish
Step-by-Step Instructions
Step 1: Prepare the Pasta and Chicken
Preheat your oven to 375°F (190°C). Cook the pasta according to package directions until al dente, then drain and set aside. While the pasta cooks, heat olive oil in a large skillet over medium-high heat. Season the chicken cubes with salt, pepper, and Italian seasoning, then cook until golden brown and cooked through, about 6-8 minutes. Remove chicken from skillet and set aside.
Step 2: Create the Creamy Pesto Sauce
In the same skillet, add the chopped onion and cook until softened, about 3-4 minutes. Add the minced garlic and cook for another minute until fragrant. Reduce heat to medium-low and stir in the pesto, heavy cream, and chicken broth. Bring to a gentle simmer, then stir in 1 cup of mozzarella cheese and all the Parmesan cheese until melted and smooth.
Step 3: Combine Everything
Add the cooked pasta and chicken to the skillet with the sauce, stirring gently to coat everything evenly. If your skillet isn’t oven-safe, transfer the mixture to a 9×13 inch baking dish. Top with the remaining 1 cup of mozzarella cheese.
Step 4: Bake to Perfection
Bake for 20-25 minutes, or until the cheese is melted and bubbly with golden spots. For extra browning, you can broil for the last 2-3 minutes. Let the pasta bake rest for 5 minutes before serving to allow the sauce to thicken slightly.
Expert Tips for the Perfect Pasta Bake
Make-Ahead Magic: Assemble the entire casserole up to 24 hours in advance. Cover and refrigerate, then bake as directed, adding 5-10 minutes to the cooking time since it will be cold from the refrigerator.
Pasta Perfection: Always cook pasta al dente since it will continue cooking in the oven. This prevents it from becoming mushy in the final dish.
Customization Options: Add sautéed mushrooms, spinach, or sun-dried tomatoes for extra flavor and nutrition. For a different twist, try our Ultimate Monterey Chicken Spaghetti which offers another delicious baked pasta variation.
Freezing Instructions: This pasta bake freezes beautifully. Cool completely, then wrap tightly and freeze for up to 3 months. Thaw in the refrigerator overnight before baking.
