With Italian sausage of your choice, bell peppers, and onions, this easy Baked Italian sausage recipe is perfect for a quick and satisfying weeknight dinner.
Arrange a rack in the center of the oven and preheat oven to 400˚F (200℃). Lightly brush a rimmed sheet pan or large baking dish with olive oil and set to the side.
Cut the bell peppers in half, remove the core and seeds and then slice them each into long ½-inch slices. Peel and thinly slice the large onion. Add the veggies to a large mixing bowl and add ½ tablespoon extra virgin olive oil , 1 teaspoon Italian seasoning, 1 teaspoon garlic powder, ½ teaspoon kosher salt, ½ teaspoon black pepper, and ¼ teaspoon crushed red pepper flakes toss to coat with the seasonings.
Arrange the Italian sausage in a single layer on the prepared baking dish, leaving at least 1-inch between each link. Spread the seasoned peppers and onions out around the sausages.
Bake for 15 minutes, remove the pan from the oven, flip the sausages and veggies. Return to the oven and continue baking for 10-15 minutes, or until the sausage has reached an internal temperature of 160°F (71°C )--for pork sausages) or 165°F (74°C)--for turkey or chicken sausages.
Serve as is, on buns, or over pasta or mashed potatoes.
Notes
For the Italian sausage: Select sweet, mild or hot uncooked Italian sausage links. Beef, pork, chicken, or turkey sausage work equally well. For precooked sausage, decrease the baking time to 18-20 minutes, flipping the sausages after 10 minutes.Bell Peppers: Use any combination of bell peppers you like or have on hand.Onion: Use a yellow or white onion for a slightly sharp flavor; use a Vidalia or sweet onion for mellow, slightly sweet flavor.Storage: Store leftover in an airtight container in the fridge for up to 4 days. Reheat on a heat-safe plate covered with a damp paper towel in 30-second intervals until warmed through. Alternatively, reheat at 350°F (177°C) for 10-15 minutes, or until warmed through.Nutrition is based on pork Italian sausage and varies per brand and variety of sausage used.
