Ingredients (Serves 4–6)

5–6 Italian sausages (mild or hot)
2 tablespoons olive oil
2 large onions, sliced
3 bell peppers (red, green, yellow), sliced
3 cloves garlic, minced
½ teaspoon dried oregano
½ teaspoon dried basil
¼ teaspoon red pepper flakes (optional)
½ cup crushed tomatoes (optional but recommended)
Salt and black pepper to taste
Fresh parsley or basil for garnish

Step-by-Step Instructions

1. Brown the Sausages

Heat 1 tablespoon olive oil in a large skillet over medium heat. Add the sausages and cook for 6–8 minutes, turning occasionally, until browned on all sides.

They don’t need to be fully cooked yet. Remove them from the skillet and set aside.

2. Sauté the Onions & Peppers

In the same pan, add the remaining tablespoon of olive oil.

Add sliced onions and cook for 4–5 minutes until they begin to soften.

Stir in the bell peppers and cook another 5–7 minutes, until tender and slightly caramelized.

Add the garlic, oregano, basil, and red pepper flakes. Cook for 30 seconds until fragrant.

3. Simmer Everything Together

Return the sausages to the pan.

Add crushed tomatoes if using. Stir gently to combine.

Cover and simmer on low heat for 10–15 minutes, until the sausages are fully cooked (internal temperature should reach 160°F / 71°C).

If desired, slice the sausages before serving or leave them whole.
