This oven baked 4-ingredient sausage and peppers pasta is my streamlined take on the classic cookout plate my husband grew up with: grilled sausage, charred peppers and onions, and a scoop of macaroni salad. Instead of juggling the grill and the stovetop, everything goes into one glass baking dish and bakes together until the sausage is juicy, the peppers are tender, and the pasta soaks up all those smoky, savory juices. It’s a very Midwestern, potluck-friendly idea—familiar flavors, simple pantry staples, and a hands-off bake that feels like a bit of a game changer on busy nights.
Serve this straight from the glass baking dish with a big slotted spoon, alongside a simple green salad tossed in a tangy vinaigrette to balance the richness. Garlic bread or buttered rolls are very welcome for soaking up the juices at the bottom of the pan. A crisp lager, light red wine, or sparkling water with lemon pairs nicely. If you want to echo those summer cookout vibes, add a side of coleslaw or sliced tomatoes with salt and olive oil.
Oven Baked 4-Ingredient Sausage and Peppers PastaServings: 6
Ingredients
12 ounces dried elbow macaroni (or other short pasta)
1 1/2 pounds fully cooked smoked sausage or Italian sausage, sliced into 1/2-inch rounds
3 large bell peppers (mixed colors), cored and sliced into thin strips
1 (24-ounce) jar marinara or tomato pasta sauce
1 teaspoon kosher salt (optional, to taste)
1/2 teaspoon freshly ground black pepper (optional, to taste)
1 tablespoon olive oil (for greasing the baking dish, optional)
1/4 cup reserved pasta cooking water (as needed, optional)
Directions
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch glass baking dish with olive oil to help prevent sticking and make cleanup easier.
Bring a large pot of well-salted water to a boil. Add the elbow macaroni and cook for 2 minutes less than the package directions for al dente. You want the pasta quite firm, since it will continue to cook in the oven.
While the pasta cooks, slice the fully cooked sausage into 1/2-inch rounds and cut the bell peppers into thin strips. If you like smaller bites, cut the pepper strips in half crosswise.
Reserve about 1/4 cup of the starchy pasta cooking water, then drain the pasta well. The pasta should still be a bit underdone at this point.
In the prepared glass baking dish, add the drained pasta, sliced sausage, and sliced bell peppers. Pour the jar of marinara sauce evenly over everything.
Use a large spoon to gently toss the pasta, sausage, peppers, and sauce together right in the baking dish until everything is evenly coated. If the mixture seems very thick or dry, stir in a splash or two of the reserved pasta water to loosen it slightly. Taste a bit of sauce and season with salt and pepper if desired.
Spread the mixture into an even layer in the dish, making sure some sausage and peppers are visible on top for better browning and color.
Cover the baking dish tightly with foil to trap steam and prevent the pasta from drying out. Place the dish on the middle rack of the preheated oven.
Bake covered for 20 minutes, then carefully remove the foil (watch for hot steam). Continue baking uncovered for another 10–15 minutes, or until the peppers are tender, the sausage is sizzling, and the pasta is fully cooked and coated in bubbling sauce.
Remove the dish from the oven and let it rest for 5–10 minutes. This short rest helps the pasta absorb a bit more sauce and makes it easier to scoop cleanly.
To serve, use a slotted serving spoon to lift generous scoops of pasta, sausage, and peppers from the glass dish, letting any excess sauce drip back. Serve hot, straight from the pan.
Variations & Tips
To stay true to the spirit of the 4-ingredient idea, the heart of this dish is simply pasta, sausage, peppers, and jarred tomato sauce, but you can still tailor it a bit. For a spicier version, use hot Italian sausage or add a pinch of red pepper flakes to the sauce before baking. If your family prefers milder flavors, choose a sweet Italian or smoked kielbasa-style sausage. You can swap elbow macaroni for any short shape like penne or rotini; just keep the pasta slightly undercooked before baking so it doesn’t turn mushy. If you miss the cheesiness of a typical baked pasta, sprinkle a light layer of shredded mozzarella or Parmesan over the top during the last 10 minutes of baking, understanding that this technically adds a fifth ingredient. For more vegetables, add sliced onions or a handful of cherry tomatoes to the pan with the peppers—again, that moves beyond the classic four but keeps the same cookout spirit. Food safety notes: this recipe is written for fully cooked sausage, which only needs to be heated through; always check the package label to confirm it is precooked. If you choose to use raw sausage links instead, remove the casings, brown the sausage in a skillet until no pink remains, drain excess fat, and then proceed with the recipe, as raw sausage should not be baked here without pre-cooking. Cool leftovers quickly, refrigerate within 2 hours, and reheat only what you plan to eat to at least 165°F (74°C) before serving.
