Description
This is the kind of dish you make when the week’s been long, the vibes are low, and you just want something cheesy, creamy, and baked to golden, bubbly perfection. Chicken Penne Casserole is a hearty, one-pan wonder packed with tender chicken, pasta, a creamy tomato sauce, and a mountain of melty cheese. It’s like your favorite pasta night—but all cozied up in casserole form.
Ingredients
– 3 cups cooked penne pasta
– 2 cups cooked, shredded chicken (rotisserie works great!)
– 1 tablespoon olive oil
– 1 small yellow onion, diced
– 3 cloves garlic, minced
– 1 teaspoon Italian seasoning
– 1/2 teaspoon crushed red pepper flakes (optional)
– 1 (24 oz) jar marinara or tomato basil pasta sauce
– 1/2 cup heavy cream or whole milk
– 1 1/2 cups shredded mozzarella cheese
– 1/2 cup grated Parmesan cheese
– Fresh basil or parsley, for garnish (optional)
Instructions
Step 1: Preheat and prep
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish or similar baking dish.
Step 2: Sauté your flavor base
In a large skillet, heat the olive oil over medium heat. Add the diced onion and cook until soft, about 5 minutes. Add garlic, Italian seasoning, and red pepper flakes, and cook for 1 more minute until fragrant.
Step 3: Build the sauce
Pour in the marinara sauce and stir to combine with the onion mixture. Reduce the heat to low and stir in the heavy cream. Let it simmer for about 5 minutes so it thickens slightly and gets extra luscious.
Step 4: Combine it all
In a big bowl (or right in the pan if it’s big enough), mix the cooked penne, shredded chicken, and sauce until everything is well coated. Stir in 1 cup of mozzarella cheese and half of the Parmesan.
Step 5: Assemble and bake
Pour the mixture into your prepared casserole dish. Sprinkle the remaining mozzarella and Parmesan over the top. Cover with foil and bake for 20 minutes. Then uncover and bake for another 10-15 minutes until the top is golden and bubbly.
Step 6: Rest and serve
Let the casserole sit for 5–10 minutes before serving so it sets up a bit. Garnish with chopped parsley or basil if you’re feeling fancy.
