Description

Oven-Baked Stuffed Pepper Pasta brings all the comforting flavors of classic stuffed peppers into an easy, cheesy pasta casserole. Tender pasta is tossed with seasoned ground beef, colorful bell peppers, onions, tomatoes, and Italian herbs before being baked beneath a golden layer of melted cheese.

It’s hearty, family-friendly, and packed with satisfying protein from the beef and cheese. This high-protein pasta bake is especially convenient for weeknight dinners because it can be assembled ahead and baked when you’re ready to eat.

Can This Oven-Baked Stuffed Pepper Pasta Support Weight Loss Goals?

Yes, it can fit into a balanced eating pattern when served in an appropriate portion. Lean ground beef and cheese provide protein, while bell peppers and tomatoes add vegetables, flavor, and fiber. Using lean beef, increasing the vegetables, and keeping the pasta and cheese portions moderate can make the dish more balanced.

Does Oven-Baked Stuffed Pepper Pasta Fit a High-Protein Lifestyle?

Yes, this casserole provides protein from lean ground beef and cheese, making it more protein-rich than a vegetable-only pasta dish. Regular pasta contributes most of the carbohydrates, so it isn’t naturally low-carb. For a higher-protein option, use protein-enriched pasta, lean beef, and extra vegetables while keeping the cheese portion moderate.

Common Mistakes to Avoid

Overcooking the pasta: Cook it slightly under al dente because it continues cooking in the oven.
Leaving excess grease in the beef: Drain the beef after browning so the casserole isn’t oily.
Using too little sauce: Pasta absorbs liquid during baking, so make sure the mixture is well coated before it goes into the oven.
Overbaking the casserole: Bake only until hot and bubbly; excessive baking can dry out the pasta.

Required Equipment

Large oven-safe skillet or Dutch oven — Makes cooking and combining the filling easy.
Large pasta pot — Provides plenty of room for pasta to cook evenly.
9×13-inch baking dish — Gives the casserole enough space for even baking.
Colander — Quickly drains the cooked pasta.
Wooden spoon — Makes breaking up and browning the beef easy.

Storage Instructions

Refrigerator: Cover the cooled casserole tightly or transfer portions to airtight containers. Refrigerate for up to 4 days.

Freezer: Freeze individual portions in freezer-safe containers for up to 2 months. For best results, thaw overnight in the refrigerator before reheating.

Reheating: Cover with foil and reheat at 350°F (175°C) for approximately 15–20 minutes, or microwave individual portions until hot. Add a splash of broth or tomato sauce if the pasta seems dry.

For meal prep, divide the casserole into individual portions after cooling to make serving sizes easier to manage.

1 tablespoon olive oil
1 medium yellow onion — diced
1 green bell pepper — diced
1 red bell pepper — diced
3 cloves garlic — minced
1 can (14.5 oz/411 g) diced tomatoes — undrained
1 can (15 oz/425 g) tomato sauce
2 tablespoons tomato paste
1 teaspoon Italian seasoning
1 teaspoon paprika
½ teaspoon black pepper
½ teaspoon salt — adjust to taste
1 cup (100 g) shredded mozzarella cheese
½ cup (50 g) shredded cheddar cheese
¼ cup (25 g) grated Parmesan cheese
2 tablespoons chopped fresh parsley — optional

Ingredient note: Use lean ground beef to reduce excess grease. Protein-enriched pasta can be substituted if you want to increase the protein content.

Directions

Preheat the oven.
Heat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
Cook the pasta.
Bring a large pot of salted water to a boil over high heat. Cook the pasta until 1–2 minutes shy of al dente according to the package directions. Drain well.
Brown the beef.
Heat olive oil in a large skillet over medium-high heat. Add the ground beef and cook for 5–7 minutes, breaking it apart until browned and fully cooked. Drain excess grease.
Cook the vegetables.
Add onion, green bell pepper, and red bell pepper. Cook over medium heat for 4–5 minutes, stirring occasionally, until the vegetables begin to soften.
Add garlic and seasonings.
Stir in garlic, Italian seasoning, paprika, black pepper, and salt. Cook for 30–60 seconds, until fragrant.
Build the tomato sauce.
Add diced tomatoes, tomato sauce, and tomato paste. Stir well and simmer over medium-low heat for 5 minutes. The sauce should be thick enough to coat the back of a spoon.
Combine with pasta.
Add the drained pasta to the skillet and stir until every piece is coated with the beef, pepper, and tomato mixture.
Transfer to the baking dish.
Spread the pasta mixture evenly in the prepared 9×13-inch dish.
Add the cheese.
Sprinkle mozzarella, cheddar, and Parmesan evenly over the top.
Bake.
Place in the 375°F (190°C) oven and bake uncovered for 20–25 minutes, until the edges are bubbling and the cheese is melted and lightly golden.
Rest before serving.
Remove from the oven and let the casserole rest for 5–10 minutes. This allows the sauce to settle and makes serving cleaner.
Garnish and serve.
Sprinkle with fresh parsley and serve warm.

High-protein cooking tip: Use 90–93% lean ground beef and protein-enriched pasta if available. Adding extra bell peppers, mushrooms, or spinach can increase the vegetable content without relying on more pasta.
