Creamy Pesto Chicken Pasta Ingredients
• Here’s what you’ll need to create this comforting dish!
For the Pasta
- Pasta (Penne or Rigatoni) – Provides the base structure; feel free to substitute with gluten-free pasta for a dietary option.
For the Chicken
- Chicken Breasts – Adds protein and flavor; rotisserie or leftover chicken can expedite your cooking time.
For the Sauce
- Olive Oil – Used for sautéing; adds richness, or you can opt for butter instead.
- Unsalted Butter – Enhances the sauce’s creaminess; can be swapped with more olive oil if desired.
- Garlic (minced) – Imparts aromatic flavor; fresh is best, but powdered works in a pinch.
- Heavy Cream and Whole Milk – Forms the creamy sauce base; increase for a richer texture.
- Basil Pesto – Infuses stunning flavor; choose store-bought or homemade, or try sun-dried tomato pesto for a twist.
- Grated Parmesan Cheese – Adds a nutty depth; aged Parmesan elevates the flavor.
To Finish
- Baby Spinach (optional) – Boosts nutrition; can be replaced with sautéed mushrooms for a vegetarian version.
- Shredded Mozzarella Cheese – Creates a crispy, bubbly topping when baked.
Step‑by‑Step Instructions for Creamy Pesto Chicken Pasta Bake
Step 1: Prepare the Baking Dish
Preheat your oven to 400°F (200°C) and lightly grease a 9×13-inch baking dish with olive oil or cooking spray. This ensures that your Creamy Pesto Chicken Pasta doesn’t stick and allows for even browning as it bakes. Having your dish ready will help you smoothly transition to the next steps.
Step 2: Cook Pasta
In a large pot, bring salted water to a boil and add your pasta, such as penne or rigatoni. Cook the pasta for 2 minutes less than the package instructions for al dente texture, as it will continue to cook in the oven. Once drained, set it aside, but don’t rinse, to keep the starch that helps the sauce adhere.
Step 3: Sauté Chicken
Heat 2 tablespoons of olive oil in a large skillet over medium heat. Season chicken breasts with salt and pepper, then add them to the skillet. Cook for about 5-6 minutes on each side until golden and cooked through, reaching an internal temperature of 165°F (75°C). Once done, remove the chicken from the skillet and let it rest while you prepare the sauce.
Step 4: Make Creamy Sauce
In the same skillet, lower the heat slightly and add 2 tablespoons of unsalted butter. Once melted, sauté 2 cloves of minced garlic until fragrant, about 30 seconds. Stir in 1 cup of heavy cream and ½ cup of whole milk, allowing it to simmer for 2-3 minutes until slightly thickened. Add in 1 cup of basil pesto and ½ cup of grated Parmesan cheese, mixing until the sauce is smooth.
Step 5: Combine Ingredients
With the creamy sauce ready, slice the sautéed chicken into bite-sized pieces and return it to the skillet. Add the drained pasta and a handful of baby spinach, if using, folding everything together gently. Ensure each piece of pasta is coated in that luscious pesto sauce for the most flavorful Creamy Pesto Chicken Pasta.
Step 6: Assemble and Top
Pour the pasta mixture into your greased baking dish, spreading it evenly. To finish, sprinkle a generous layer of shredded mozzarella cheese and a bit more grated Parmesan on top. This will melt beautifully and create a golden, bubbly crust as it bakes.
Step 7: Bake
Place the prepared dish in your preheated oven and bake uncovered for 20-25 minutes. Watch for the cheese to become a lovely golden brown and the edges to bubble, indicating that your Creamy Pesto Chicken Pasta is perfectly baked and ready to take out.
Step 8: Rest and Serve
Once baked, remove the dish from the oven and let it rest for about 5 minutes. This helps the flavors settle and makes it easier to serve. Then, dish out generous portions of your Creamy Pesto Chicken Pasta Bake and enjoy the aroma and warmth that fills your home!
