📖Why My Recipe Works

We're using fresh, uncooked Italian sausage. Unlike pre-cooked sausage, fresh sausage retains its natural moisture and fat during cooking, ensuring a juicy and flavorful result.
Adding the sauce on the side makes reheating and dipping easy. It also allows the veggies to fully caramelize.

🧾Ingredient Notes

Italian Sausage- You can use mild, spicy, or sweet Italian sausage, depending on your preference. For a leaner option, you can use turkey or chicken sausage.
Bell Peppers- Adds a subtle sweetness to the dish. Use red, yellow, green, or orange bell peppers or a combination of these.
Onions- White onions or yellow onions both work.
Marinara Sauce- Use my homemade San Marzano sauce or any store-bought marinara.
Parmesan Cheese- Swap with pecorino romano.
Fresh Basil- Fresh oregano and parsley also work.
Seasonings- Add red pepper flakes for a spicy kick.

⏲️How to Make Baked Italian Sausage

A baking sheet filled with sliced yellow and red bell peppers, onions, savory baked Italian sausage, and seasoning, with metal tongs and a cloth in the corner.

On a large baking sheet, spread the bell peppers and onion and toss to coat with olive oil and seasonings. Arrange the sausage links among the veggies to let them soak up the flavors.

Sliced onions and bell peppers with baked Italian sausages are arranged on a baking tray, ready for cooking, on a dark countertop with a cloth beside.

When baking the sausage, flip it halfway through and stir the peppers to ensure even cooking and prevent them from burning quickly. After flipping add the sauce in an oven proof bowl before returning to the oven.

A baking tray features a delicious spread of baked Italian sausage alongside sliced bell peppers and onions, perfectly roasted. A bowl of rich red sauce sits invitingly on the side.

The sausage is fully cooked when it reaches an internal temperature of 160°F and when it is golden brown and slightly crispy on the outside. Top with fresh basil and parmesan.

🥗What to Serve with Sausage and Peppers

I love to pair baked sausage and peppers with garlic bread for a flavorful side, or a house salad or Caesar salad for a fresher and lighter option.

You can turn this into a pasta dish by serving it over marinara sauce and your favorite pasta. It’s the perfect meal when you’re craving something filling!

Leftovers make fantastic subs, just load them into a soft bun and enjoy! Top with pesto for a unique twist that takes the flavors to the next level.

👩🏻‍🍳 Expert Tips

Prep the onions and peppers the day before for an easy weeknight dinner.
Top the sausages with fresh mozzarella in the last five minutes of baking for a melty, gooey finish.
