Sheet Pan Sausage and Peppers

Sheet pan sausage and peppers is the kind of weeknight dinner that actually makes you feel like you have dinner under control. One pan, bold flavors, and ready in 30 minutes. I threw this together on a Tuesday after school pickup and soccer practice, and my teenagers asked for seconds before I even sat down.

There is something about the smell of Italian sausage roasting with sweet bell peppers and red onion that just feels like comfort food done right. This sheet pan sausage and peppers recipe has become my go-to when I need something fast, filling, and high in protein without overthinking it. The caramelized edges on the vegetables are where all the flavor lives. Trust me, this one is worth every minute.

Ingredients for Sheet Pan Sausage and Peppers

I have made this recipe enough times to know that your sausage choice really sets the tone. I always use sweet Italian sausage when I am cooking for the kids, but hot Italian is my personal favorite when it is just the adults.

1 lb Italian sausage (sweet, mild, or hot), casings removed
2 large bell peppers (any color), sliced (I recommend one red and one yellow for the best sweetness and color)
1 large red onion, sliced
2 tbsp olive oil (in my experience, do not skip this, it is what helps everything caramelize properly)
1 tsp Italian seasoning
1/2 tsp garlic powder
1/2 tsp salt
1/4 tsp black pepper
Fresh parsley, chopped (optional, for garnish, my preference is to always add it since it brightens the whole dish)

Step-by-Step Instructions

I recommend reading through all the steps before you start. This recipe moves fast and a little prep upfront makes it totally stress-free.

Step 1: Preheat your oven to 400 degrees F (200 degrees C). Line a large baking sheet with parchment paper for easy cleanup.

Step 2: Add the sliced bell peppers and red onion to a large bowl. Drizzle with olive oil and sprinkle in the Italian seasoning, garlic powder, salt, and black pepper. Toss until everything is evenly coated. Pro tip: really take your time here so every piece gets seasoned.

Step 3: Break the Italian sausage into small chunks, roughly 1 to 2 inch pieces, and add them directly to the bowl with the vegetables. Toss everything together until the sausage is well mixed in with the veggies.

Step 4: Spread the sausage and vegetable mixture in a single, even layer on your prepared baking sheet. This step is important: do not crowd the pan. If everything is piled on top of each other, it will steam instead of roast and you will lose all that caramelization. Use two baking sheets if needed.

Step 5: Roast for 20 to 25 minutes, stirring halfway through at the 10 to 12 minute mark, until the sausage is fully cooked through (internal temp of 160 degrees F) and the vegetables are tender with slightly caramelized edges. For a flavor boost, add a splash of balsamic vinegar during the last 5 minutes of roasting.

Step 6: Remove from the oven, garnish with fresh parsley if desired, and serve hot.

What to Serve with Sheet Pan Sausage and Peppers

This dish is satisfying on its own, but the right sides round out the meal in both flavor and nutrition. Here are my favorite ways to serve it:

Hoagie Rolls: Pile the sausage and peppers into a toasted hoagie roll for a classic Italian sandwich. It is the most popular way we eat this at my house.

Pasta or Rice: Serve over pasta or steamed rice to stretch the meal further and soak up all of those savory roasted pan juices. If you love pasta nights, my High Protein Chicken Fajita Pasta uses a similar approach and is just as easy.

Melted Mozzarella or Provolone: Scatter shredded cheese over the hot pan right when it comes out of the oven and let it melt for about 2 minutes. Absolutely worth the extra step.

Marinara Sauce: A warm bowl of marinara on the side for dipping pulls all the Italian flavors together beautifully.

Simple Green Salad: A crisp salad balances the richness of the sausage. My Mediterranean Tuna Salad works great as a light starter alongside this.

Sausage and Potato Bowl: If you want to turn this into a full sheet pan bowl situation, my Sausage and Potato Breakfast Bowls use a very similar flavor base and are great for meal prep inspiration.

Storage and Serving Tips

Store any leftovers in an airtight container in the refrigerator for up to 4 days. For longer storage, transfer to a freezer-safe bag or container and freeze for up to 3 months. Label the bag with the date so you always know what you have on hand.

To reheat, I recommend warming in a skillet over medium heat for the best texture. You can also reheat in the oven at 350 degrees F until warmed through. Avoid the microwave if you can since it tends to make the vegetables soft and watery.

Pro tip: this sheet pan sausage and peppers recipe is one of the best things you can add to your weekly meal prep rotation. Make a double batch, divide into portions, and pair with rice or pasta throughout the week for fast, high-protein lunches.
