Gluten-Free Spicy Italian Sausage and Peppers Skillet

aka The Tuscan Firehouse Skillet

There’s nothing like coming home after a long day and throwing together a one-skillet meal that fills the whole kitchen with the most incredible aroma. I started making this sausage and peppers skillet years ago when I realized most of my favorite Italian comfort foods were already naturally gluten-free — no fancy substitutes needed. The sweet peppers caramelize beautifully against the spicy sausage, and with a drizzle of good olive oil and fresh basil, it tastes like something straight out of a trattoria. My friends always ask for this recipe, and now it’s yours too.

Ingredients

• 1½ lbs Italian sausage links (hot or mild — check labels for gluten-free), casings removed
• 2 tablespoons extra virgin olive oil
• 3 large bell peppers (1 red, 1 yellow, 1 orange), seeded and sliced into strips
• 1 large yellow onion, halved and sliced into half-moons
• 4 cloves garlic, minced
• 1 pint cherry tomatoes, halved
• ½ teaspoon red pepper flakes (adjust to taste)
• 1 teaspoon dried oregano
• ½ teaspoon smoked paprika
• ½ teaspoon sea salt
• ¼ teaspoon freshly ground black pepper
• ¼ cup fresh basil leaves, torn
• 1 tablespoon balsamic vinegar (verify GF on label)

Instructions

1. Brown the sausage: Heat 1 tablespoon of EVOO in a large cast iron skillet over medium-high heat until shimmering (about 2 minutes). Add the sausage, breaking it into rough 1-inch chunks with a wooden spoon. Cook for 6-7 minutes, turning occasionally, until deeply browned on all sides and cooked through (internal temp 165°F). Transfer to a plate.
2. Sauté the peppers and onions: Add the remaining 1 tablespoon EVOO to the same skillet. Add the sliced bell peppers and onion. Cook over medium-high heat for 5-6 minutes, stirring every minute or so, until the peppers are tender-crisp and the onions are translucent with light char marks.
3. Add aromatics: Push the vegetables to the edges and add the minced garlic to the center. Cook for 30-45 seconds until fragrant — don’t let it brown. Stir it into the vegetables.
4. Add tomatoes and spices: Add the halved cherry tomatoes, red pepper flakes, oregano, smoked paprika, salt, and pepper. Stir everything together. Cook for 3-4 minutes until the tomatoes just start to soften and release their juices.
5. Combine and finish: Return the sausage to the skillet and toss everything together. Cook for 2 more minutes to let the flavors meld. Drizzle with balsamic vinegar and toss. Remove from heat.
6. Garnish and serve: Top with torn fresh basil leaves. Serve hot — great on its own, over rice, or with a simple green salad.

Tips

• Check your sausage labels! Many Italian sausages are naturally gluten-free, but some brands add fillers. Look for short ingredient lists with just pork, spices, and natural casings.
• Don’t crowd the skillet. If your pan isn’t big enough, brown the sausage in batches for better caramelization.
• Make it a meal: Serve over cooked rice, cauliflower rice, or gluten-free polenta for a heartier dinner.
• Leftovers are even better the next day — the flavors develop overnight. Store in an airtight container for up to 4 days.
