This oven baked 4-ingredient sausage and peppers pasta is exactly the kind of weeknight secret my uncle swears by: toss everything on a foil-lined sheet pan, bake, stir in pasta, and dinner is done. It hits all the cozy Midwestern comfort notes—cheesy, saucy, a little char on the peppers and sausage—without a ton of dishes or effort. If you’re juggling work, kids, and a never-ending to‑do list, this is the kind of recipe that makes you feel like you’ve got it together, even on a Tuesday.
Serve this sausage and peppers pasta straight from the foil-lined sheet pan with a big metal spoon—family-style and low-fuss. A simple green salad with a tangy vinaigrette or some steamed broccoli balances the richness. If you have time, warm up some garlic bread or a crusty baguette to soak up the extra sauce. A sprinkle of red pepper flakes and extra grated cheese at the table lets everyone customize their bowl. For drinks, pair with a light red wine, a cold beer, or sparkling water with lemon.
Oven Baked 4-Ingredient Sausage and Peppers Pasta
Servings: 6

Ingredients
1 pound uncooked rigatoni pasta (or similar short pasta)
1 1/2 pounds Italian sausage, casings removed and sliced into 1/2-inch pieces (sweet or hot)
3 large bell peppers, seeded and sliced into strips (any colors you like)
1 (24-ounce) jar marinara or tomato pasta sauce
Kosher salt, to taste (optional, for the pasta water and adjusting seasoning)
Freshly ground black pepper, to taste (optional, for serving)
Olive oil spray or 1 tablespoon olive oil (optional, for greasing the foil)
Grated Parmesan or mozzarella cheese, for serving (optional)
Directions
Preheat your oven to 425°F (220°C). Line a large rimmed baking sheet with aluminum foil, making sure it comes up the sides for easy cleanup. Lightly spray or brush the foil with a little olive oil if you’re worried about sticking.
Spread the sliced Italian sausage and bell pepper strips evenly over the prepared baking sheet. Try to keep everything in a single layer so it roasts instead of steams.
Drizzle very lightly with olive oil if using, and season with a pinch of salt and pepper if you like. Toss right on the sheet pan with your hands or a spoon so the sausage and peppers are coated and evenly distributed.
Bake the sausage and peppers for 20–25 minutes, stirring once about halfway through, until the sausage is cooked through (no pink in the center) and the peppers are tender with some charred edges. If you want extra char, you can broil for 2–3 minutes at the end, watching closely so nothing burns.
While the sausage and peppers are roasting, bring a large pot of salted water to a boil. Cook the rigatoni according to package directions until just al dente. Drain well, reserving about 1/2 cup of the pasta cooking water in case you want to loosen the sauce later.
When the sausage and peppers are done, remove the pan from the oven. Carefully pour the jar of marinara sauce directly over the hot sausage and peppers on the sheet pan. Use a spoon to gently stir and scrape up any browned bits from the foil—those add a lot of flavor.
Add the drained rigatoni to the sheet pan. Use a large metal spoon or tongs to toss everything together right on the foil-lined pan until the pasta is well coated in sauce and the sausage and peppers are evenly mixed throughout. If the mixture looks too thick or dry, splash in a little of the reserved pasta water and toss again until it’s glossy and saucy.
Return the sheet pan to the oven and bake for another 5–10 minutes, just until everything is hot and the edges are bubbling. This helps the flavors meld and gives a slightly roasted taste to the sauce.
Carefully remove the pan from the oven. Let it sit for a couple of minutes, then taste and adjust seasoning with a bit more salt and pepper if needed. Serve directly from the foil-lined baking sheet with a big metal serving spoon, and top individual portions with grated Parmesan or mozzarella if you like.
Variations & Tips
You can easily tweak this 4-ingredient base to fit your family and what you have on hand. Swap the Italian sausage for chicken sausage or turkey sausage if you prefer something lighter, or use hot Italian sausage if your crew likes a little kick. Any color bell pepper works—red and yellow are sweeter, while green is a bit more savory and old-school. If you want extra veggies without changing the core idea, you can add sliced onions or a handful of grape tomatoes to the sheet pan with the peppers. For a creamier version, stir a splash of heavy cream or a spoonful of ricotta into the sauce before adding the pasta. To make it spicier, add red pepper flakes over the finished dish. Food safety tips: Always cook sausage until it reaches an internal temperature of at least 160°F (71°C) for pork or 165°F (74°C) for poultry sausage, and make sure there’s no pink remaining. Wash your hands, cutting board, and knife thoroughly after handling raw sausage. Don’t leave the finished pasta out at room temperature for more than 2 hours; cool leftovers quickly and store them in an airtight container in the refrigerator for up to 3–4 days. Reheat fully until steaming hot before serving.
