Ingredients
🍝 1 lb pasta (penne, rigatoni, or ziti)
🧴 2 tbsp olive oil
🍗 2 cups cooked chicken, diced or shredded
🧀 2 cups shredded mozzarella cheese
🧀 1 cup grated parmesan cheese
🥛 1 ½ cups heavy cream
🧂 Salt and pepper to taste
Optional add-ins: sautéed mushrooms, steamed broccoli, spinach, or red pepper flakes for heat
Instructions
1. Cook the Pasta
Boil your pasta according to the package instructions until just al dente. Drain and set aside.
2. Make the Creamy Sauce
In a large saucepan, heat the olive oil over medium heat. Add in the cooked chicken and stir for 1–2 minutes. Pour in the heavy cream, season with salt and pepper, and let simmer gently for 5 minutes.
3. Combine Everything
In a large mixing bowl or directly in a greased baking dish, combine the cooked pasta, chicken cream mixture, mozzarella, and parmesan cheese. Stir until evenly mixed.
4. Bake
Transfer the mixture into a 9×13-inch baking dish. Sprinkle a bit of extra cheese on top if desired. Bake in a 375°F oven for 20–25 minutes, until the top is golden and bubbly.
5. Serve
Let rest for a few minutes, then scoop and serve hot with a sprinkle of parsley or extra parmesan.
Tips for Success
- Don’t overcook your pasta—it’ll keep cooking in the oven
- Add sautéed garlic or Italian seasoning to the sauce for more depth
- Use a blend of cheeses like provolone or fontina for extra richness
- Make it meatless with mushrooms and spinach instead of chicken
