Ingredients
- Penne or rigatoni pasta: The sturdy shape holds up in the sauce and bakes beautifully Look for bronze-cut or Italian brands for the best texture
- Boneless skinless chicken breasts: Boneless chunks cook quickly and stay juicy Choose breasts that are plump and free of excess fat
- Olive oil: Adds flavor and helps brown the chicken Go for extra-virgin if you can
- Salt and black pepper: Essential for bringing out all the layers of flavor
- Unsalted butter: Gives the sauce a rich base Use real butter for that creamy finish
- Garlic: Adds depth and a savory kick Fresh cloves are best instead of pre-minced
- Heavy cream: Makes the sauce luscious and silky Use heavy or double cream for proper richness
- Whole milk: Balances out the cream so it is not too heavy Whole milk is ideal
- Basil pesto: Brings the signature herby taste Use homemade or a good store-bought kind with lots of basil and real Parmesan
- Grated Parmesan cheese: Gives a nutty cheesy flavor throughout Freshly grated is best for melting smoothly
- Baby spinach (optional): Boost of greens adds nutrition Look for bright green leaves with no wilting
- Shredded mozzarella cheese: Melts into a bubbly golden crown on top Whole-milk mozzarella gets the best stretch
- Extra Parmesan cheese: Finishes the bake with a savory sharpness
Instructions
- Preheat the Oven:
- Set your oven to 200 degrees Celsius or 400 degrees Fahrenheit and lightly grease your baking dish This step makes sure nothing sticks and helps the cheese turn that gorgeous golden brown
- Cook the Pasta:
- Bring a large pot of salted water to a boil Add your pasta and cook it for two minutes less than the package says You want it just under al dente since it will finish baking in the sauce Drain it and set aside so it is ready to toss
- Brown the Chicken:
- While the pasta cooks heat olive oil in your skillet on medium-high Season your chicken well with salt and pepper Add the chicken in a single layer Let it sauté without moving for a couple of minutes then stir until all the pieces are just cooked through and have a slight golden color This keeps them juicy and flavorful Take the chicken out of the pan and set aside
- Build the Creamy Pesto Sauce:
- In the same pan melt the butter on medium heat Once hot add the minced garlic Stir constantly for just thirty seconds until aromatic watch closely to keep it from burning
- Simmer the Cream and Milk:
- Pour in the heavy cream and whole milk Use a spatula to scrape up any browned bits from the pan Bring to a gentle simmer and cook for two to three minutes until the sauce starts to thicken slightly
- Add Pesto and Parmesan:
- Stir in the pesto and grated Parmesan cheese Mix until the sauce is smooth and the cheese has melted fully Taste and adjust for salt and pepper as needed
- Combine the Pasta Chicken and Spinach:
- Pour the cooked pasta chicken and baby spinach if using into the sauce Carefully toss everything together so each piece is lovingly coated and the spinach just wilts from the heat
- Assemble the Bake:
- Transfer the mixture to your prepared baking dish Spread it out evenly Top with shredded mozzarella and extra Parmesan for that irresistible cheesy crust
- Bake Until Golden and Bubbly:
- Place the dish on the center rack and bake for twenty to twenty five minutes The top should be beautifully browned and bubbling Let it rest for five minutes before scooping out so everything keeps its shape
Save I always sneak in extra spinach whenever I make this and it simply melts into the sauce My mom used to say you could taste the sunshine in any meal with good basil pesto and I think she was right
Storage Tips
Store leftovers covered in the fridge for up to four days The baked pasta keeps its creamy texture because of the rich sauce Reheat individual portions in the microwave or return the whole dish to the oven covered with foil and bake until heated through You can freeze the entire casserole either before or after baking Wrap tightly to prevent freezer burn and defrost overnight in the fridge before reheating
Ingredient Substitutions
Substitute rotisserie chicken or leftover roast chicken to save on prep Try whole-wheat or gluten-free pasta for different dietary needs If you want a vegetarian version skip the chicken and double the spinach or use sautéed mushrooms for hearty flavor
Serving Suggestions
Serve alongside a simple green salad or roasted vegetables to balance the richness Pair with garlic bread or a crusty Italian loaf for mopping up extra sauce If you like a touch of heat sprinkle a pinch of red pepper flakes over the top before baking
Cultural Context
This dish is a mashup of classic Italian basil pesto and the American love for ultra-comforting casseroles It brings together old world flavors with the ease of a familiar bake In Italy pasta al forno often uses simple tomato sauce but here the creamy pesto twist offers something totally new It is a great way to introduce basil pesto to picky eaters because the cheese and cream make it extra approachable
Seasonal Adaptations
Swap in sun-dried tomato pesto for a summery red color Use fresh peas or asparagus chopped and stirred in with the pasta during spring months Roast cherry tomatoes on top before baking for a sweet tangy pop of flavor Choose the right pasta shape so it will hold the sauce and cheese Using good aged Parmesan is key for nutty depth Do not be afraid to pack in extra greens or herbs based on what is in season
Success Stories
Kids devour this even when packed with spinach I once made this bake for a neighbor with a new baby and she said it was the best thing she ate all week One friend uses this recipe to sneak more protein into her teenage son's diet by tossing in white beans
Freezer Meal Conversion
Assemble everything in your baking dish but stop before the final bake Wrap tightly in foil and freeze up to three months Bake straight from the freezer at a lower temperature twenty minutes longer until everything is hot and bubbly
Save This cozy casserole always goes fast at my house and it is the ultimate comfort food for cold nights or big celebrations. Make it once and it just might become your new favorite dinner tradition.
