A super tasty and classic combination! This Sausage and Peppers sheet pan dinner comes together in under 30 minutes, and is so adaptable. It’s naturally gluten free and dairy free as well. Try it with different kinds of sausages, or add the optional tomatoes for a fun twist. It’s great with simple side dishes like my Creamy Mashed Cauliflower, or with freshly cooked pasta.



1 pound mild or hot uncooked Italian sausage links

2 red bell peppers, 1 pound, cut into 1/2” slices

1 red onion, 12 ounces

2 tablespoons olive oil

1 clove garlic, minced

1 teaspoon Italian seasoning, see notes

1 teaspoon sea salt, or to taste

1/2 teaspoon ground black pepper

Option 1: 2 cups cherry tomatoes, 10 ounces

Option 2: 1-2 cups favorite tomato basil pasta sauce warmed up to drizzle on top

Garnish: Chopped basil and freshly grated parmesan if desired


Preheat the oven to 450ºF.

Cut the onion in half and remove the tough outer layer. Lay each half flat side down and cut across the rounded top to create 1/4″ thick half moon slices.

Place the peppers and onions on a large cookie sheet. Mix together the olive oil, garlic, Italian seasoning, sea salt, and pepper. Drizzle the oil mixture over the peppers and onions, and toss to combine.

Spread the peppers and onions out evenly, then top with the 4 sausages. If you’re using the cherry tomatoes, add them evenly across the baking sheet at this point.

Bake for 10 minutes, then turn the oven up to broil at 550ºF for 5-10 minutes until the peppers and onions are browning and the sausages are done. Keep a close eye on it while it’s broiling!

You can also bake this for 25-30 minutes, or until the sausages are done at 450º, but there won’t be quite as much browning.

Garnish with basil and parmesan if desired and serve with your choice of sides. If you’re using the tomato sauce, be sure to warm it up and drizzle over the top of the finished dinner, or serve it on the side.


Check to make sure you Italian seasoning is free from salt, sugar, dairy, or any other additives. The same goes for the sausage, some brands put cheese in Italian sausage, so be sure to check the labels.
