Ingredients & Substitutions

Ingredient List

• 2 teaspoons olive oil
• 1 lb Italian sausage (sweet, mild, or spicy)
• 1 cup white onion, sliced
• 1 cup red onion, sliced
• 1 red bell pepper, sliced
• 1 yellow bell pepper, sliced
• 1 orange bell pepper, sliced
• 3 garlic cloves, sliced
• ¾ teaspoon kosher salt
• ½ teaspoon black pepper
• ¼ teaspoon red pepper flakes
• ½ cup chicken broth (or red wine for a richer flavor)
• 1 tablespoon chopped parsley
• 2 tablespoons fresh basil

Possible Substitutions

• Swap Italian sausage for chicken sausage, turkey sausage, or plant-based alternatives
• Use only one type of bell pepper if that’s what you have on hand
• Replace chicken broth with vegetable broth or red wine for a deeper flavor
• Add mushrooms or zucchini for extra veggies

Step-by-Step Instructions

1. Brown the Sausage

Heat olive oil in a large skillet over medium-high heat. Add the sausage links and cook for about 2 minutes per side until browned. Remove from the skillet and slice into pieces.

2. Cook the Onions and Peppers

In the same skillet, add the sliced onions and cook for 2 minutes, stirring frequently. Add the sliced bell peppers, garlic, salt, black pepper, and red pepper flakes. Sauté for 5 minutes until the onions become translucent.

3. Deglaze the Pan

Pour in the chicken broth (or red wine) and use a wooden spoon to scrape up any browned bits from the bottom of the skillet. This adds rich flavor to the dish.

4. Simmer Everything Together

Return the sliced sausage to the skillet, lower the heat to medium, and cover. Simmer for 10 minutes, allowing the flavors to meld.

5. Finish and Serve

Uncover, increase the heat to medium-high, and cook for 3 more minutes until most of the liquid evaporates and the sausage is fully cooked. Garnish with chopped parsley and fresh basil before serving.

Expert Tips & Tricks

Best Practices for Maximum Flavor

• Browning the sausage first locks in its juices and enhances flavor
• Cutting the onions and peppers into even slices ensures they cook uniformly
• Deglazing with wine instead of broth adds depth and richness

Common Mistakes to Avoid

• Skipping the deglazing step results in missing out on a lot of flavor
• Overcooking the vegetables can make them mushy—keep an eye on them
• Using too much salt early on—season lightly at first and adjust later

Time-Saving Tips

• Use pre-sliced onions and peppers to cut down on prep time
• Make it ahead and reheat for a quick meal during busy nights
• Double the recipe and freeze portions for later
