August 25, 2025

This tasty dish features juicy sausages, colorful bell peppers, and sweet onions, all roasted together in the oven. It’s a perfect meal that’s simple and full of flavor!

You can’t go wrong with the aroma of herbs and spices filling your kitchen. I love serving it on a hoagie or with crusty bread. You’re gonna want seconds, trust me! 😋

Key Ingredients & Substitutions

Italian Sausage: The type of sausage you choose can change the dish’s flavor. Mild is great for a classic taste, while spicy brings a kick. Chicken or turkey sausage can be a lighter option, perfect for those watching their fat intake.

Bell Peppers: A mix of colors adds vibrancy. You can swap out bell peppers for other varieties like poblano or even zucchini for a different flavor. If bell peppers aren’t available, frozen mixed peppers work too!

Onion: Sweet onions, like Vidalia, add a lovely flavor, while yellow onions provide a sharper taste. If you’re in a hurry, pre-chopped onions save time! You can even use shallots for a delicate flavor.

Garlic: Fresh garlic is preferred, but garlic powder can work in a pinch. Just use about 1/4 teaspoon for every clove you substitute. Roasted garlic can also be a flavorful addition!

How Do I Ensure the Sausage is Perfectly Cooked?

Cooking the sausage so it’s juicy inside and nicely browned outside is crucial. Here’s how to do it:

  • Make sure the oven is preheated—this ensures even cooking.
  • Use, preferably, a large baking pan to give the sausages space to brown.
  • Turn the sausages halfway through cooking to avoid any undercooked spots.
  • Check for doneness using a meat thermometer—it should read 160°F (70°C) for pork sausages.

By following these tips, your dish will not only taste amazing but also look great on the plate! Enjoy!

Ingredients You’ll Need:

For the Dish:

  • 6 Italian sausage links (mild or spicy, as preferred)
  • 3 bell peppers (a mix of red, green, and yellow), sliced into strips
  • 1 large onion, sliced into rings
  • 3 cloves garlic, minced
  • 2 tablespoons olive oil
  • 1 teaspoon dried Italian seasoning (or a mix of oregano, basil, and thyme)
  • 1/2 teaspoon crushed red pepper flakes (optional, for heat)
  • Salt and freshly ground black pepper, to taste
  • 1 tablespoon balsamic vinegar (optional, for added depth)
  • Fresh parsley, chopped (for garnish)

How Much Time Will You Need?

This recipe will take about 10 minutes to prep and around 30-40 minutes to cook. So, in total, you’re looking at about 50 minutes from start to enjoying this delicious meal!

Step-by-Step Instructions:

1. Preheat the Oven:

Start by preheating your oven to 400°F (200°C). This ensures everything cooks evenly and gets that lovely roasted flavor you want.

2. Prepare the Veggies:

In a large mixing bowl, toss together the sliced bell peppers, onion rings, and minced garlic. Drizzle with the olive oil, and add the Italian seasoning, crushed red pepper flakes (if using), and a good pinch of salt and pepper. Mix everything well to coat the veggies evenly in the oil and seasonings.

3. Spread and Arrange:

Transfer the seasoned peppers and onions to a large baking sheet or roasting pan. Spread them out nicely so they all cook evenly. Now, nestle the whole sausage links right on top of the vegetables. This allows the flavors to mingle beautifully!

4. Roasting Time:

Place the baking sheet in your preheated oven and roast for about 30-40 minutes. Be sure to turn the sausages halfway through cooking. You want them to be browned and cooked through, while the vegetables become tender and caramelized.

5. Add a Flavor Boost:

If you’re feeling fancy, drizzle the balsamic vinegar over everything once it’s out of the oven. Give it a gentle toss to mix. This little step adds a nice depth of flavor!

6. Serve and Enjoy:

Remove the pan from the oven and garnish your dish with fresh chopped parsley. Serve this delicious mix hot, either on its own, with crusty bread, over rice, or as a filling in hoagie rolls for a mouth-watering sausage and peppers sandwich.

Enjoy your flavorful and easy oven-baked sausage, peppers, and onions! It’s perfect for weeknight dinners or gatherings with friends!
