This slow cooker 3-ingredient Italian sausage and peppers recipe is my go-to when the day is packed and I still want the house to smell like I’ve been cooking for hours. A retired neighbor of mine, who spent years feeding a big family on a tight schedule, showed me this foil-pouch trick: you bundle everything together, let the heat do the work, and end up with tender, juicy sausage and silky peppers swimming in their own rich juices. It’s rooted in the classic Italian-American combination of sausage and peppers, but streamlined for busy weeknights—no browning, no fuss, just three simple ingredients and a slow cooker.

Serve the sausages and peppers straight from the foil pouch over creamy polenta, buttered egg noodles, or a bed of steamed rice to soak up the savory juices. For a more traditional Italian-American approach, tuck a sausage and plenty of peppers into a warm hoagie roll and spoon some of the cooking liquid over the top. A simple green salad with a tangy vinaigrette and a glass of red wine or sparkling water with lemon balances the richness nicely. Leftovers make excellent sandwich fillings or can be chopped and folded into frittatas the next day.

Servings: 4

8 links (about 2 pounds) uncooked Italian sausage (sweet or hot)

Prepare the slow cooker and foil: Tear off a large sheet of heavy-duty aluminum foil, about 18–20 inches long. If your slow cooker is wide, you may want two overlapping sheets to create a sturdy pouch. Lay the foil in the slow cooker insert so it comes partway up the sides, forming a shallow bowl in the center.

Layer the peppers: Scatter the sliced bell peppers evenly over the center of the foil, keeping them in a loose mound so they’ll sit directly under the sausages. This bed of peppers will soften and soak up the sausage juices as everything cooks.

Add the sausage: Arrange the Italian sausage links snugly on top of the peppers in a single layer. It’s fine if they touch or slightly overlap; they’ll shrink a bit as they cook and release their fat and flavor into the peppers below.

Pour on the sauce: Spoon the pasta sauce evenly over the sausages and peppers, making sure each link gets at least a little coating. You don’t need to drown the mixture; the sauce is there to add flavor and a bit of moisture, and it will combine with the sausage drippings as it cooks down.

Seal the foil pouch: Bring the long sides of the foil up and over the sausages and peppers, then fold them together tightly to seal. Fold up the short ends as well, crimping firmly so the pouch is closed but not pressed hard against the food. You want a loose, sealed package that traps steam and juices while it cooks.

Slow cook: Cover the slow cooker with its lid. Cook on LOW for 6–7 hours or on HIGH for 3–4 hours, until the sausages are cooked through (no pink in the center) and the peppers are very soft and tender. The contents of the foil pouch will have created a rich, savory broth.

Rest and open carefully: Turn off the slow cooker and let the foil pouch sit for about 5 minutes. Carefully open the foil away from your face and hands—hot steam will escape. Transfer the sausages and peppers, along with as much of the cooking juices as you like, to a serving platter or individual plates.

Serve: Serve the sausages whole or sliced, nestled with the peppers and spooned with their juices. Taste the peppers and juices and add a pinch of salt at the table if needed, depending on how seasoned your sausage and sauce are.

Use this basic foil-pouch method as a template. For leaner results, choose turkey or chicken Italian sausage; they’ll still baste the peppers but with less fat. If you like a bit more heat, use hot Italian sausage or stir a pinch of red pepper flakes into the sauce before sealing the pouch. You can also swap in yellow or orange bell peppers for a sweeter flavor, or add a sliced onion to the pepper layer if you don’t mind stretching beyond three ingredients. For a heartier, almost stew-like dish, increase the pasta sauce to 1 1/2 cups and add a splash of water or broth. Leftovers keep well in the refrigerator for up to 3 days; reheat gently on the stovetop with a spoonful of water, or tuck the sliced sausage and peppers into crusty rolls with a slice of provolone and toast under the broiler for quick sandwiches. If you don’t have a slow cooker, you can place the foil pouch on a rimmed baking sheet and bake at 375°F (190°C) for about 50–60 minutes, until everything is tender and cooked through.
