How to Make Creamy Pesto Chicken Pasta Bake

Prepare Baking Dish and Preheat Oven: Preheat your oven to 400°F (200°C). Lightly grease a 9×13-inch baking dish.
Cook Pasta: Bring salted water to a boil in a large pot. Cook pasta for 2 minutes less than the package suggests, so it’s slightly underdone. Drain and set aside.
Sauté Chicken: Heat olive oil in a large skillet over medium-high heat. Season diced chicken with salt and pepper, then cook until golden brown and fully cooked, about 5–6 minutes. Remove chicken and set aside.
Make Creamy Pesto Sauce: In the same skillet, melt butter over medium heat. Add minced garlic and sauté until fragrant, about 30 seconds. Pour in heavy cream and milk. Simmer for 2–3 minutes, then stir in basil pesto and Parmesan cheese until the sauce thickens slightly.
Combine Ingredients: Add cooked pasta, chicken, and spinach to the creamy pesto sauce. Toss until everything is evenly coated.
Assemble and Top: Pour the mixture into the prepared baking dish. Sprinkle mozzarella and grated Parmesan evenly over the top.
Bake: Bake uncovered for 20–25 minutes until the cheese is golden and bubbly.
Rest and Serve: Let the dish rest for 5 minutes before serving. Allowing it to cool slightly will help the flavors meld together beautifully.

How to Customize This Creamy Pesto Chicken Pasta Bake for Your Diet

Low-carb: Swap traditional pasta with zucchini noodles or a low-carb pasta alternative.
Keto-friendly: Use heavy cream exclusively and skip the milk. Opt for a cheese-heavy topping.
Vegetarian: Replace chicken with sautéed mushrooms or roasted chickpeas for plant-based protein.
Nut-free: Choose a nut-free pesto brand or make your own using sunflower seeds instead of pine nuts.
Gluten-free: Select gluten-free pasta, such as brown rice or quinoa pasta.
