This stuffed pepper and pasta casserole, made with just five ingredients, is exactly the kind of dish a good neighbor brings when you’re not feeling well: cozy, familiar, and nutritious enough to serve as dinner, all in one deep casserole dish. It combines the flavors of classic Midwestern stuffed peppers—ground meat, green bell pepper, tomato, rice, and plenty of melted cheese—with a pasta dish you can reheat all week long.
The method is intentionally simple: everything is mixed, covered, and fried until the pasta, rice, and bell peppers are cooked, the top is bubbling, and the edges are golden brown.
Serve this stuffed bell pepper pasta straight from the baking dish with a simple green salad with a fresh vinaigrette to balance the richness of the dish. Warm garlic bread or a crusty baguette is ideal for scooping up any sauce leftovers that collect in the corners of the dish. A light red wine such as a Chianti or a smooth Zinfandel pairs well, while sparkling water with lemon is refreshing if you are feeling a bit under the weather. Leftovers can easily be reheated and supplemented with steamed broccoli or green beans for a dish with more vegetables.
Preheat the oven to 190 °C (375 °F). Lightly grease a deep oval baking dish (with a capacity of approximately 3 liters) with cooking spray or a little oil. This shape provides a classic, homey look and makes it easy to scoop out the contents with a wooden spoon.
Heat the olive oil in a large skillet over medium heat. Add the ground meat and break it up with a wooden spoon. Season with 1 teaspoon kosher salt and 1/2 teaspoon black pepper. Cook the meat, stirring occasionally, until it is no longer pink and most of the excess liquid has evaporated, 6-8 minutes. Drain off any excess fat if necessary to prevent the casserole from becoming too greasy.
While the beef is cooking, cut the green bell peppers into bite-sized pieces. They should be large enough to be clearly distinguishable in the casserole, like traditional stuffed pepper pieces, but not so large that they overpower every bite.
Place the uncooked pasta, uncooked rice, and sliced green bell pepper in a large mixing bowl. Stir everything together well so that it is evenly distributed. This dry mixture will absorb the sauce and moisture in the oven, giving you that characteristic texture of stuffed bell pepper rice combined with tender pasta.
Add the cooked minced meat to the bowl with the pasta, rice, and bell pepper. Pour in the entire jar of tomato sauce and the 4 cups of water. Stir everything well so that no dry lumps of pasta or rice stick to the bottom of the bowl. The mixture will now look quite liquid and soupy – that is intentional, so that the pasta and rice can cook in the oven.
Taste the liquid (just a small spoonful) and season to your liking with some extra salt and pepper, keeping in mind that the cheese will also add some salt later.
Pour the mixture into the prepared deep oval baking dish and spread it into an even layer so that the pasta and rice are completely submerged in the liquid. Cover the dish tightly with aluminum foil and fold the edges closed to trap the steam; this is crucial for cooking the rice and pasta.
Bake the dish covered for 45-55 minutes, until the rice and pasta are just cooked. Start checking after about 40 minutes by carefully removing the foil and tasting a small spoonful from the center. If the pasta or rice still has a firm center, cover it again and continue baking in increments of 5-10 minutes.
As soon as the pasta and rice are cooked and most of the liquid has been absorbed into a thick sauce, remove the foil. Sprinkle the grated mozzarella evenly over the top so that the surface is covered, but leave a few small openings so that you can still see the beef and bell peppers through it.
Return the dish to the oven without the lid and bake for another 10-15 minutes, until the cheese is fully melted, bubbling, and starting to brown around the edges. If you prefer a deeper golden brown top, you can switch the oven to the grill setting for 1-2 minutes at the end. Keep a close eye on the dish to prevent burning.
Remove the baking dish from the oven and let the stuffed bell pepper pasta rest for at least 10 minutes. This short resting time allows the rice and pasta to settle and the sauce to thicken slightly, so that every spoonful of pasta remains firm when you lift it with a wooden spoon.
Serve warm and scoop generous portions directly from the deep oval dish. You should see strands of melted cheese, tender beef, pasta with rice grains, and bright green bell peppers in every bite—exactly the kind of comforting, shareable casserole a thoughtful neighbor would leave on your doorstep.
You can easily adapt this 5-ingredient concept to what you have at home. For a slightly lighter version, you can replace the ground beef with ground turkey or chicken and use a tomato-basil marinade for extra flavor. If you like a bit of heat, add a pinch of red chili flakes or use a spicy arrabbiata sauce instead of regular pasta sauce.
You can use yellow, orange, or red bell peppers (partially or fully) instead of green; they provide a sweeter, less pronounced flavor while retaining the character of stuffed peppers. For a more classic, typically American Midwestern flavor, you can use a mozzarella-cheddar mixture for a richer, slightly sharper topping. If you prefer a softer pepper, cut the peppers into smaller pieces; for more bite, you can leave them in larger chunks.
