Brown the Sausage – Heat olive oil in a large skillet/Dutch oven over medium heat. Brown sausages on all sides (not fully cooked). Remove and set aside.
Sauté the Vegetables – In the same pan, cook onions and peppers for 8–10 minutes until soft and lightly caramelized. Stir in garlic, oregano, and red pepper flakes.
Deglaze the Pan – Add white wine (or broth) and scrape up browned bits.
Add Tomatoes & Simmer – Stir in crushed tomatoes. Season with salt and pepper. Return sausages to the pan. Cover and simmer 20–25 minutes, until sausages are cooked through.
Garnish & Serve – Top with fresh basil or parsley. Serve warm.
Notes
Use good-quality sausage for the best flavor.
Don’t rush the vegetables — slow cooking brings out sweetness.
Mix sweet and hot sausages for a balanced spice level.
