Grilled Sausage with Peppers and Onions Recipe

This incredibly easy 30 Minute Meal is low on effort and high on flavor. Grilled Sausage with Peppers and Onions comes together quickly: smoky kielbasa roasted on the grill, paired with caramelized onions and colorful peppers tossed in a sweet-and-spicy sauce. Serve piled into a bun, on a roll, or plated without bread for a lighter meal.

Polish kielbasa is a family favorite and always a crowd-pleaser. What makes this dish special is the glaze: a simple mix of tomato paste, brown sugar, red wine vinegar, garlic, garlic powder, and sriracha that caramelizes on the vegetables as they cook. The result is sweet, tangy, slightly spicy, and full of rich, caramelized flavor that complements the smoky sausage.

How to make Grilled Sausage with Peppers and Onions

This is a straightforward supper ideal for backyard dinners, tailgating, or a busy weeknight. The grill does most of the work—just set things up and monitor until everything is golden and caramelized. Using indirect heat for the sausage prevents flare-ups and ensures even cooking while you finish the vegetables in a hot skillet.

Set up a gas or charcoal grill for indirect cooking: heat the coals or burners on one side and leave the other side cooler. While the grill heats, portion the kielbasa and slice the bell peppers and red onion into 1/4″ strips. Mix the sweet-and-spicy sauce so it’s ready when the vegetables reach tender-crisp.

Place the kielbasa on the indirect side of the grill and roast until golden and just beginning to split, about 20 minutes. At the same time, preheat a 10″ cast-iron skillet directly over the heat and add a little olive oil. Add the sliced onions, peppers, and a pinch of salt, sautéing briefly until they begin to soften. Move the skillet to the indirect side of the grill to finish cooking while the sausages continue to roast.

When the veggies are tender-crisp—typically after 5–10 minutes on the indirect side—stir in the sauce. Let it bubble and reduce just enough to cling to the onions and peppers, then continue cooking until the sauce becomes fragrant and the vegetables are caramelized to your liking. Meanwhile, toast buns over the coals or flame if you like a slightly charred roll for serving.

Can I use something besides a cast iron skillet?

Yes. Black steel pans, griddles, woks, or other cookware designed for direct heat will work well on the grill. Avoid items with plastic or rubber handles and non-stick coatings that aren’t rated for high heat.

Serving suggestions: place the sliced kielbasa in a toasted hoagie or brat bun and spoon the caramelized peppers and onions over the top. For a lower-carb option, serve the sausage and vegetables on a platter with a side salad. Leftovers make a great topping for baked potatoes, scrambled eggs, or pasta the next day.
