This oven baked 5-ingredient stuffed pepper pasta is exactly the kind of dish a good neighbor brings when you’re under the weather: cozy, familiar, and hearty enough to be dinner in one deep baking dish. It borrows the flavors of classic Midwestern stuffed peppers—ground beef, green bell peppers, tomato, rice, and plenty of melted cheese—and tucks them into a pasta bake that can be reheated all week.
The method is intentionally simple: everything gets mixed, covered, and baked until the pasta, rice, and peppers are all tender and the top is bubbling and browned at the edges.
Serve this stuffed pepper pasta straight from the baking dish with a simple green salad dressed in a sharp vinaigrette to cut through the richness. Warm garlic bread or a crusty baguette is ideal for scooping up the saucy bits that collect in the corners of the pan. A light red wine like a Chianti or a mellow Zinfandel pairs nicely, while sparkling water with lemon keeps things refreshing if you’re on the mend. Leftovers reheat well and can be rounded out with a side of steamed broccoli or green beans for a more vegetable-forward plate.
Oven Baked 5-Ingredient Stuffed Pepper Pasta
Servings: 6
Preheat the oven to 375°F (190°C). Lightly grease a deep oval baking dish (about 3-quart capacity) with nonstick spray or a little oil. This shape helps mimic that classic neighborly casserole look and makes it easy to scoop with a wooden spoon.
In a large skillet over medium-high heat, warm the olive oil. Add the ground beef, breaking it up with a wooden spoon. Season with 1 teaspoon kosher salt and 1/2 teaspoon black pepper. Cook, stirring occasionally, until the beef is no longer pink and any excess moisture has mostly cooked off, 6–8 minutes. Drain off excess fat if needed to keep the bake from becoming greasy.
While the beef cooks, chop the green bell peppers into bite-size pieces. You want them large enough to stay distinct in the bake, like traditional stuffed pepper chunks, but not so big that they dominate each bite.
In a large mixing bowl, combine the uncooked pasta, uncooked rice, and chopped green peppers. Stir to distribute everything evenly. This dry mix will soak up the sauce and water in the oven, giving you that stuffed-pepper rice texture along with tender pasta.
Add the cooked ground beef to the bowl with the pasta, rice, and peppers. Pour in the entire jar of tomato pasta sauce and the 4 cups of water. Stir very well, making sure there are no dry pockets of pasta or rice stuck at the bottom of the bowl. The mixture will look quite loose and soupy at this point—that’s what you want for the pasta and rice to cook through in the oven.
Taste the liquid (just a small spoonful) and adjust the seasoning with a bit more salt and pepper if desired, remembering that the cheese will add some saltiness later.
Pour the mixture into the prepared deep oval baking dish, smoothing it into an even layer so the pasta and rice are submerged in the liquid. Cover the dish tightly with foil, crimping the edges to keep steam in; this is crucial for cooking the rice and pasta all the way through.
Bake, covered, for 45–55 minutes, until the rice and pasta are just tender. Begin checking around the 40-minute mark by carefully removing the foil and tasting a small spoonful from the center. If the pasta or rice still has a firm core, recover and continue baking in 5–10 minute increments.
Once the pasta and rice are tender and most of the liquid is absorbed into a thick, saucy mixture, remove the foil. Sprinkle the shredded mozzarella cheese evenly over the top, covering the surface but leaving a few little gaps so you still see some of the beef and peppers peeking through.
Return the dish to the oven, uncovered, and bake for another 10–15 minutes, until the cheese is fully melted, bubbling, and starting to brown in spots around the edges. If you like a deeper golden top, you can switch the oven to broil for 1–2 minutes at the end, watching closely to avoid burning.
Remove the baking dish from the oven and let the stuffed pepper pasta rest for at least 10 minutes. This short rest allows the rice and pasta to settle and the sauce to thicken slightly, so each scoop holds together when lifted with a wooden spoon.
Serve warm, scooping generous portions straight from the deep oval dish. You should see strands of melted cheese, tender beef, rice-studded pasta, and bright green pepper pieces in every spoonful—exactly the sort of comforting, shareable bake a thoughtful neighbor would leave on your doorstep.
You can easily adapt this 5-ingredient concept to fit what you have on hand. For a slightly lighter version, swap the ground beef for ground turkey or chicken and use a tomato-basil marinara for extra flavor. If you enjoy a bit of heat, add a pinch of red pepper flakes or use a spicy arrabbiata-style sauce in place of plain pasta sauce.
Yellow, orange, or red bell peppers can be used in part or entirely instead of green; they’ll lend a sweeter, less assertive flavor while keeping the stuffed-pepper character. To lean more into classic Midwestern comfort, use a mozzarella-cheddar blend for a richer, slightly sharper top. If you prefer a softer pepper texture, dice the peppers smaller; for more bite, keep them in larger chunks.
For a gluten-free version, use gluten-free pasta and confirm your jarred sauce is gluten-free; you may need to add an extra splash of water if your pasta absorbs more liquid. For meal prep, assemble the dish up to the point of baking, cover, and refrigerate for up to 24 hours; add 10–15 minutes to the covered bake time if starting from cold.
Food safety tips: Always cook ground beef to a safe internal temperature of 160°F (71°C); browning it thoroughly before baking helps ensure this. If you assemble the casserole ahead, keep it refrigerated at or below 40°F (4°C) and do not leave it at room temperature for more than 2 hours. Leftovers should be cooled quickly, stored in shallow containers in the refrigerator, and eaten within 3–4 days, reheated until steaming hot in the center before serving.
