Ingredients

1 pound Italian sausage (sweet or spicy)
3 bell peppers (red, yellow, or green), sliced
1 large onion, sliced
3 cloves garlic, minced
2 tablespoons olive oil
1/2 teaspoon salt
1/2 teaspoon black pepper
1 teaspoon Italian seasoning
1/2 teaspoon crushed red pepper flakes (optional)
1/2 cup chicken broth or water
1 tablespoon tomato paste (optional for extra flavor)
Fresh parsley for garnish (optional)

Kitchen Tools Needed

Large skillet or sauté pan
Cutting board
Sharp knife
Wooden spoon or spatula
Measuring spoons

Step-by-Step Directions

Step 1: Prepare the Vegetables

Wash the bell peppers and slice them into thin strips. Slice the onion into similar-sized strips so they cook evenly. Mince the garlic and set it aside.

Step 2: Brown the Sausage

Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the Italian sausages and cook them for about 6 to 8 minutes, turning occasionally until they are browned on all sides. The sausages do not need to be fully cooked yet.

Remove the sausages from the pan and set them aside on a plate.

Step 3: Cook the Peppers and Onions

Add the remaining tablespoon of olive oil to the same skillet. Add the sliced onions and peppers and cook over medium heat. Stir occasionally and cook for about 8 to 10 minutes until the vegetables soften and begin to caramelize.

Step 4: Add Garlic and Seasoning

Stir in the minced garlic, salt, black pepper, Italian seasoning, and crushed red pepper flakes if using. Cook for about 1 minute until the garlic becomes fragrant.

Step 5: Combine with Sausage

Slice the browned sausages into thick pieces or leave them whole depending on your preference. Return the sausage to the skillet with the peppers and onions.

Step 6: Add Liquid and Simmer

Pour the chicken broth into the skillet and add the tomato paste if using. Stir well and bring the mixture to a gentle simmer. Cover the pan and cook for about 10 to 12 minutes until the sausages are fully cooked and the flavors blend together.

Step 7: Finish and Serve

Remove the lid and allow any excess liquid to cook down for a few minutes if needed. Taste and adjust seasoning if necessary. Garnish with fresh parsley before serving.

Cooking Tips

Use a mix of red, yellow, and green bell peppers for the best color and flavor.
Sweet Italian sausage gives a mild flavor, while hot Italian sausage adds spice.
Cooking the vegetables slowly helps them caramelize and become sweeter.
For extra flavor, add a splash of balsamic vinegar at the end of cooking.

Storage Instructions

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in a skillet over medium heat or in the microwave until warmed through.

This dish can also be frozen for up to 2 months. Thaw overnight in the refrigerator before reheating.
