Key Ingredients & Substitutions

Italian Sausage

Sweet Italian sausage is the classic choice. It has a mild fennel flavor and works well with the sweetness of peppers and onions.

Hot Italian sausage adds heat and bold flavor. Mild Italian sausage is great for families. Chicken or turkey Italian sausage also works, but it is leaner and may need a little extra olive oil.

Bell Peppers

Use a mix of red, yellow, orange, and green bell peppers. Red, yellow, and orange peppers are sweeter. Green peppers taste sharper and more classic.

Choose firm peppers with shiny skin and no soft spots.

Onions

Yellow onions are best because they become sweet as they cook. White onions also work. Red onions add a stronger flavor and deeper color.

Garlic

Fresh garlic gives the dish a warm Italian flavor. Garlic powder can work in a pinch, but fresh is better.

Crushed Tomatoes

Crushed tomatoes make the dish saucy and rich. Use good canned crushed tomatoes or passata.

For a lighter version, skip the tomatoes and use broth with a splash of wine.

Tomato Paste

Tomato paste adds deep flavor. Cooking it for a minute makes the sauce taste richer.

Olive Oil

Olive oil helps brown the sausage and soften the vegetables. Extra virgin olive oil adds the best flavor.

Italian Seasoning

Italian seasoning usually includes oregano, basil, thyme, and rosemary. You can also use dried oregano and fresh basil.

Red Pepper Flakes

Red pepper flakes add heat. Use a little for mild spice or more if you like it hot.

Broth or Red Wine

Chicken broth keeps the sauce savory. A splash of red wine gives the sauce deeper flavor. Either works well.

How to Make Italian Sausage and Peppers

Step 1 — Brown the Sausages

1. Heat the pan. Warm olive oil in a large skillet or Dutch oven over medium heat.
2. Brown the sausage. Add the sausages and cook until browned on all sides. They do not need to be fully cooked yet.
3. Remove and rest. Transfer the sausages to a plate. This keeps them juicy while you cook the vegetables.

Step 2 — Sauté the Vegetables

4. Cook the onions. Add sliced onions to the same pan. Cook until they begin to soften and turn golden.
5. Add the peppers. Stir in the sliced bell peppers. Cook until they soften but still hold some shape.
6. Add garlic and seasoning. Stir in garlic, Italian seasoning, red pepper flakes, salt, and pepper. Cook just until fragrant.

Step 3 — Simmer to Perfection

7. Add tomato paste. Stir in the tomato paste and cook for 1 minute. This makes the sauce taste deeper.
8. Deglaze the pan. Add broth or red wine and scrape the browned bits from the bottom of the pan.
9. Add crushed tomatoes. Stir in the crushed tomatoes until the sauce looks rich and smooth.
10. Return the sausage. Place the sausages back into the pan. Cover and simmer until the sausages are fully cooked.

Step 4 — Serve and Enjoy

11. Slice or serve whole. You can serve the sausages whole or slice them into thick pieces.
12. Finish with herbs. Add fresh basil or parsley before serving for a bright, fresh flavor.

Pro Tips for the Best Italian Sausage and Peppers

Brown the sausage first. This builds flavor in the pan and helps the sausage stay juicy.

Do not burn the garlic. Add garlic after the peppers soften. Burnt garlic can taste bitter.

Use colorful peppers. A mix of colors makes the dish sweeter and prettier.

Cook the onions slowly. Soft, lightly caramelized onions make the whole dish taste richer.

Deglaze the pan. Broth or wine lifts the browned bits from the bottom and adds flavor to the sauce.

Simmer gently. A low simmer keeps the sausage tender. A hard boil can make it tough.

Toast the hoagie rolls. If serving sandwiches, toasted rolls hold up better to the sauce.
