Making it, step by step

Step 1: Preheat the Oven
Preheat your oven to 400°F (200°C) and position the oven rack in the center. While the oven heats up, prepare a large, deep, rimmed metal sheet pan by lightly greasing it with 1 tablespoon of olive oil. The oil helps prevent sticking and allows for easy cleanup later.

Step 2: Prepare the Peppers
Rinse the red, yellow, and green bell peppers under running water, then dry them with a clean kitchen towel. Carefully remove the stems, seeds, and white membranes. Slice each bell pepper into thick, even strips that will caramelize nicely in the oven, creating a colorful base for your Baked Italian Sausage and Peppers in Marinara Sauce.

Step 3: Slice the Onions and Garlic
Next, peel the yellow onions and cut them into thick wedges, separating the layers as you go. Mince the 5 cloves of garlic finely, as you'll be adding this for a robust flavor in the marinara sauce. The combination of sweet onions and aromatic garlic will enhance the dish beautifully.

Step 4: Season the Vegetables
In a large mixing bowl, combine the sliced bell peppers and onions. Drizzle the remaining 2 tablespoons of olive oil over the vegetables, then sprinkle in the dried Italian seasoning, basil, oregano, thyme, rosemary, garlic powder, onion powder, smoked paprika, salt, and pepper. Toss everything thoroughly until the vegetables are evenly coated with the seasoned oil.

Step 5: Roast the Vegetables
Spread the seasoned peppers and onions evenly across the prepared sheet pan. Place the pan in the preheated oven and roast for about 15 minutes until the vegetables start to soften and turn slightly golden. You'll notice a delicious aroma filling your kitchen as they roast.

Step 6: Add the Sausages
Carefully remove the sheet pan from the oven after 15 minutes. Use a large spatula to turn the roasted peppers and onions, ensuring even cooking. Next, arrange the Italian beef sausages over the vegetables. Return the sheet pan to the oven and roast for an additional 15 minutes, watching for the sausages to develop golden-brown edges.

Step 7: Prepare the Marinara Sauce
While the sausages roast, grab a medium mixing bowl and pour in the marinara sauce. Add the crushed tomatoes, tomato paste, balsamic vinegar, Worcestershire sauce, minced garlic, and a teaspoon of granulated sugar to balance the acidity of the tomatoes. Mix everything thoroughly until well combined, creating a rich, flavorful sauce.

Step 8: Combine Sauce with Vegetables and Sausages
When the sausages are nicely browned, remove the sheet pan from the oven again. Use kitchen tongs to turn each sausage, gently tossing the peppers and onions. Pour the prepared marinara sauce evenly around the sausages and vegetables. Aim to submerge the peppers and onions partially in the sauce, spooning a bit over each sausage for extra flavor.

Step 9: Final Bake
Return the sheet pan to the oven and bake for another 20 to 25 minutes. Look for the sauce to become thick and bubbly while ensuring the sausages reach an internal temperature of at least 160°F (71°C). You want them fully cooked and infused with the rich flavors of the marinara.

Step 10: Rest and Garnish
Once the sausages are fully cooked, remove the sheet pan from the oven. Let the dish rest in the marinara sauce for about 5 minutes. Gently stir the roasted peppers and onions into the sauce. Taste the sauce and adjust the seasoning as needed, then sprinkle freshly grated Parmesan cheese evenly over the hot dish.

Step 11: Serve and Enjoy
Scatter finely chopped parsley over the top for a fresh finish. Serve your Baked Italian Sausage and Peppers in Marinara Sauce warm, accompanied by cooked pasta, steamed rice, or toasted sandwich rolls. This hearty meal is perfect for family gatherings or cozy weeknight dinners.
