I bring smoky Cajun sausage with blistered green peppers and sweet onions that yields an impossibly flavorful one-pan dinner.

Jump to Recipe

I adore the mess-free glory of sausage and peppers sheet pan dinners. Give me smoky kielbasa searing against the char of green bell peppers and I am instantly sold.

It’s loud and unapologetic on the plate, all caramelized edges and punchy Cajun seasoning that kicks through without being precious. I love the way the sausage’s fat glints, the peppers blistering and holding their snap.

It feels like dinner that actually wants to be eaten, not dissected. But mostly I love that it tastes like real food, bold, simple, and impossible to ignore.

No messing around. I want it every weeknight.

Print Recipe (No Advertisments)

1. Preheat oven to 425 F (220 C) and line a large rimmed baking sheet with foil or parchment for easy cleanup.

2. Slice 1 1/2 lb smoked sausage into 1/2 inch rounds, core and slice 3 medium green bell peppers into 1/2 inch strips, and cut 1 large yellow or sweet onion into 1/2 inch wedges.

3. In a big bowl, toss the sausage, peppers, and onion with 2 tbsp olive oil until everything is lightly coated.

4. Sprinkle on 1 1/2 to 2 tsp Cajun seasoning (use 1 1/2 tsp if you want milder), 1 tsp garlic powder, 1 tsp smoked paprika, 1/2 tsp kosher salt, 1/4 tsp black pepper, and 1/4 tsp red pepper flakes if you want extra heat. Toss again so the spices coat everything.

5. Spread the sausage and veggies in a single layer on the prepared sheet pan, leaving a little space between pieces so they roast instead of steam.

6. Roast in the preheated oven for 20 minutes, then use a spatula to flip and stir everything so the edges brown evenly.

7. Return the pan to the oven and roast another 8 to 12 minutes, or until the peppers are tender and the sausage has some nice browning and crisp edges.

8. Taste and adjust seasoning if needed, let the pan rest 3 to 5 minutes so juices settle.

9. Sprinkle with 2 tbsp chopped fresh parsley if you like and serve straight from the sheet pan over rice, pasta, or crusty bread.

10. Leftovers keep well sealed in the fridge for 3 to 4 days and reheat nicely in a skillet to regain some crispness.

FAQ

Can I use a different sausage? Yes, definitely. Kielbasa, smoked Italian, or even chicken apple sausage all work. Just pick a smoked or flavorful variety so the veggies dont taste bland.

Can I use other peppers or veggies? Sure. Red, yellow, or orange bell peppers taste great. You can also add sliced zucchini, mushrooms, or cherry tomatoes, but add softer veggies later so they don't turn to mush.

How do I know when it's done? The sausage should be browned and the peppers and onions should be tender with some char at the edges. About 20 to 25 minutes at 425 F usually does it, stirring once halfway through.

Can I make this ahead or freeze it? You can roast it ahead and refrigerate for up to 3 days. Reheat in a 375 F oven until warmed through. Freezing is ok but the peppers get softer after thawing, so best for meal prep not for serving to guests.

What can I serve it with? Serve over rice, pasta, crusty bread, or inside hoagie rolls for sandwiches. Add a dollop of mustard or hot sauce if you like more zip.

How spicy will this be? Mild to medium depending on the Cajun seasoning and red pepper flakes. Start with 1 1/2 tsp and add to taste, or skip the flakes if you want no heat at all.

Sausage And Peppers Sheet Pan Dinner Recipe Substitutions and Variations

Sausage: swap for turkey or chicken sausage for a leaner meal, or sliced smoked tofu for a vegetarian option. If using tofu press it first so it browns better.
Green bell peppers: use red or yellow bell peppers for sweeter flavor, or poblano peppers for a bit more heat and smokiness.
Cajun seasoning: replace with 1 1/2 tsp Italian seasoning plus 1/4 tsp cayenne if you want a different herb profile but still some kick, or use smoked paprika and a pinch of chili powder.
Fresh parsley garnish: sub with chopped cilantro or basil for a different finish, basil gives a sweeter lift while cilantro adds brightness.

Pro Tips

Alright here we go, quick and messy like someone typed it while the oven was preheating.

Preheat your oven to 425 F. Line a big rimmed baking sheet with foil or parchment so you dont have to scrub later. Slice about 1 1/2 pounds of smoked sausage into half inch rounds, core and slice three green bell peppers into half inch strips and chop one large sweet onion into half inch wedges. Toss everything in a big bowl with two tablespoons of olive oil until it looks slick. Add 1 1/2 to 2 teaspoons Cajun seasoning depending on how brave you feel, a teaspoon garlic powder, a teaspoon smoked paprika, half a teaspoon kosher salt, a quarter teaspoon black pepper and a pinch of red pepper flakes if you want it spicy. Toss again so the spices coat everything good.

Spread the sausage and veggies in a single layer on the sheet, dont crowd them or theyll steam instead of getting that nice brown edge. Roast for 20 minutes, then scrape and flip everything with a spatula so both sides get some color. Put it back for another 8 to 12 minutes until the peppers are tender and the sausage has crispy bits. Taste and add a little more salt or Cajun if it needs a kick. Let it sit for 3 to 5 minutes so the juices settle.

Serve right off the pan over rice, pasta or on crusty bread, sprinkle a couple tablespoons of chopped fresh parsley if you want it to look fancy. Leftovers keep 3 to 4 days in the fridge and reheat best in a skillet so the sausage gets back some crunch.

A couple real life tips i always use:
– Don’t skip spacing stuff out on the pan, otherwise you end up with soggy peppers. If your pan is small roast in two batches.
– If you want extra char, broil for 1 to 2 minutes at the end watching closely, things go from perfect to burned fast.
– Use smoked sausage with good fat content, it bails out the veggies and adds flavor so you dont need tons of oil.
– If you like more depth, toss in a splash of Worcestershire or a squeeze of lemon right after roasting, it wakes everything up.
