The 5-Star Ingredients

This recipe proves that you do not need a long ingredient list to create something delicious. Here is what you will need:

Pasta – 12 ounces (penne, rotini, or shells). Pasta is the hearty base of this casserole. Short shapes work best because they hold the sauce and filling beautifully.

Ground beef – 1 pound. Ground beef is the savory, hearty protein that makes this dish satisfying. As it browns, it creates a rich, meaty flavor.

Bell peppers – 2 large, chopped. Bell peppers add sweetness, color, and a tender texture. Use a mix of red, green, and yellow for the best presentation.

Tomato sauce – 1 jar (24 ounces). Tomato sauce creates the rich, tangy base that ties all the ingredients together.

Shredded mozzarella cheese – 2 cups. Mozzarella adds a classic, gooey, melted topping that makes this casserole irresistible. You can also use cheddar or a blend of Italian cheeses.

That is it. Five ingredients. No onions. No garlic. No complicated steps. Just honest, delicious ingredients that come together beautifully.

Step-by-Step Instructions

Step 1: Preheat and Prep

Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.

Step 2: Cook the Pasta

Bring a large pot of salted water to a boil. Cook the pasta according to package directions until al dente. Drain and set aside.

Step 3: Brown the Ground Beef

In a large skillet over medium heat, cook the ground beef until browned and fully cooked, breaking it up as it cooks. Drain off any excess grease.

Step 4: Add the Peppers and Sauce

Add the chopped bell peppers to the skillet and cook for 3 to 4 minutes, until slightly softened. Stir in the tomato sauce and simmer for 5 minutes.

Step 5: Combine with Pasta

Add the cooked pasta to the skillet and stir until everything is evenly coated in the sauce.

Step 6: Transfer to the Baking Dish

Pour the mixture into the prepared baking dish and spread it into an even layer.

Step 7: Top with Cheese

Sprinkle the shredded mozzarella cheese evenly over the top.

Step 8: Bake

Bake for 20 to 25 minutes, until the casserole is hot and bubbly and the cheese is melted and golden.

Step 9: Rest and Serve

Let the casserole rest for 5 minutes before serving.
