Ingredients

To make this delicious baked rotini casserole, you’ll need:

  • 12 oz rotini pasta: The spiral shape holds the sauce and cheese perfectly.
  • 1 lb Italian sausage (or ground beef): Adds savory flavor and a hearty texture.
  • 1 small onion, chopped: Enhances the flavor of the sausage.
  • 2 cloves garlic, minced: Adds depth and a classic Italian aroma.
  • 2 cups marinara sauce: The tangy base that ties the casserole together.
  • 1 cup ricotta cheese: Adds creaminess and richness.
  • 1 1/2 cups shredded mozzarella cheese, divided: Melts beautifully and creates a gooey top layer.
  • 1/2 cup grated Parmesan cheese: Adds a nutty, savory flavor.
  • 12-15 pepperoni slices: Provides a pizza-inspired topping.
  • 1 tsp Italian seasoning: A blend of herbs that enhances the marinara sauce.
  • Salt and pepper to taste: Essential for balancing flavors.
  • Fresh parsley, chopped (for garnish): Adds a pop of color and freshness.

How to Make Baked Rotini Casserole

Follow these simple steps to create a cheesy, satisfying baked rotini casserole:

1. Preheat the Oven

Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish to prevent sticking.

2. Cook the Rotini Pasta

Bring a large pot of salted water to a boil. Cook the rotini pasta according to package instructions until al dente. Drain and set aside. Cooking the pasta al dente ensures it holds up during baking without becoming mushy.

3. Prepare the Meat Sauce

In a large skillet over medium heat, cook the Italian sausage and chopped onion until the sausage is browned and the onion is softened, about 5-7 minutes. Add the minced garlic and cook for another minute, stirring frequently. Stir in the marinara sauce, Italian seasoning, salt, and pepper. Let the sauce simmer for 5 minutes, then remove from heat.

4. Mix the Cheese Filling

In a mixing bowl, combine the ricotta cheese, 1 cup of mozzarella cheese, and Parmesan cheese. Mix until well blended. This mixture will add creaminess to the casserole layers.

5. Assemble the Casserole

In the greased baking dish, layer the cooked pasta, meat sauce, and ricotta mixture. Gently stir to combine all ingredients evenly. This ensures every bite has a balance of pasta, sauce, and cheese.

6. Add the Topping

Sprinkle the remaining 1/2 cup of mozzarella cheese over the top of the casserole. Arrange the pepperoni slices evenly on top for a fun, pizza-inspired finish.

7. Bake the Casserole

Cover the dish with foil and bake in the preheated oven for 20 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly, with golden edges.

8. Garnish and Serve

Once baked, remove the casserole from the oven and let it rest for a few minutes. Garnish with chopped parsley for a fresh, vibrant touch. Serve hot and enjoy!

Tips for the Best Baked Rotini Casserole

  • Use Quality Marinara Sauce: A good marinara sauce enhances the overall flavor. Opt for one with natural ingredients and minimal sugar.
  • Don’t Overcook the Pasta: Cooking the pasta al dente ensures it won’t become too soft after baking.
  • Experiment with Toppings: Swap the pepperoni for cooked bacon, olives, or mushrooms for a unique twist.
  • Let it Rest: Allow the casserole to rest for 5-10 minutes before serving to make slicing and plating easier.

Serving Suggestions

This baked rotini casserole is a complete meal on its own, but it pairs wonderfully with classic sides for a full Italian-inspired feast:

  • Garlic Bread: Perfect for soaking up the extra sauce and cheese.
  • Caesar Salad: A crisp, tangy salad balances the richness of the casserole.
  • Roasted Vegetables: Serve with roasted zucchini, asparagus, or bell peppers for added nutrition.

Frequently Asked Questions

A: Yes! Assemble the casserole, cover it tightly, and refrigerate for up to 24 hours. Add a few extra minutes to the baking time if starting from cold.
