How to Make Stuffed Pepper Pasta
Step 1: Cook the Pasta
Preheat your oven to 375°F (190°C). Cook the pasta in a large pot of salted boiling water until just slightly underdone. Drain well and set aside.
Step 2: Cook the Beef and Peppers
Heat a large skillet over medium heat. Add the ground beef and cook until browned, breaking it apart as it cooks. Drain any excess grease if necessary.
Add the diced bell peppers and cook for about 4–5 minutes, until they begin to soften.
Step 3: Combine Everything
Stir the tomato sauce into the beef and pepper mixture. Add the cooked pasta and mix until everything is evenly coated with sauce.
Transfer the mixture to a lightly greased baking dish and spread it into an even layer.
Step 4: Add the Cheese
Sprinkle the shredded mozzarella evenly over the top. Make sure the cheese covers most of the pasta so it becomes beautifully golden and bubbly in the oven.
Step 5: Bake
Bake uncovered for about 20–25 minutes, or until the cheese is melted and lightly golden around the edges.
Let the pasta rest for 5 minutes before serving.
Tips for the Best Results
Don’t overcook the pasta before baking because it will continue cooking in the oven. For extra flavor, you can use a combination of red and green bell peppers. If you prefer a cheesier casserole, add a little extra mozzarella on top.
Allowing the pasta to rest briefly after baking also helps the sauce settle and makes it easier to serve.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3–4 days. Reheat individual portions in the microwave or warm the entire casserole in the oven until heated through.
Conclusion
This 5-Ingredient Stuffed Pepper Pasta is a simple way to turn familiar ingredients into a satisfying baked dinner. The combination of savory beef, sweet peppers, rich tomato sauce, tender pasta, and melted mozzarella makes it a family-friendly meal that’s easy to prepare and perfect for busy evenings.
