Step‑by‑Step Instructions for Italian Sausage Peppers and Onions
Step 1: Heat the Oil
Start by heating 2 tablespoons of extra-virgin olive oil in a large skillet over medium heat. Allow the oil to shimmer but not smoke, indicating it’s hot enough to sauté. This will create a flavorful base for your Italian Sausage Peppers and Onions, setting the stage for the deliciousness to come.
Step 2: Cook the Sausage
Add 1 pound of sweet Italian sausage to the skillet, breaking it apart with a wooden spoon. Cook for about 7-10 minutes, stirring occasionally, until the sausage is browned and cooked through. Once it’s nicely browned, carefully remove it from the skillet and drain any excess fat, leaving the flavorful bits behind.
Step 3: Sauté the Aromatics
With the skillet still over medium heat, introduce the sliced onions and colorful bell peppers to the pan, along with 4 chopped garlic cloves. Sauté everything for about 2-3 minutes until the vegetables start to soften and the garlic becomes fragrant. This aromatic mix will enhance the robust flavors of the Italian Sausage Peppers and Onions.
Step 4: Add Seasonings
Sprinkle in 1 tablespoon of Italian seasoning and 1/4 cup of chopped fresh basil, stirring to combine with the veggies. Cook for another 2 minutes to allow the herbs to release their flavors and infuse the dish with a delightful aroma. You’ll know it’s ready when the onions are translucent, creating the perfect backdrop for the sausage.
Step 5: Deglaze the Skillet
Pour in 1 cup of Marsala wine (or chicken broth if you prefer) and scrape the bottom of the skillet with a wooden spoon to deglaze it. Add 2 tablespoons of tomato paste and a 15-ounce can of diced tomatoes, stirring to blend everything together. This mixture will form a rich, tasty sauce for the Italian Sausage Peppers and Onions.
Step 6: Bring to a Simmer
Introduce the sliced peppers and onions back into the skillet, seasoning with 1 teaspoon of kosher salt and 1 teaspoon of black pepper. Increase the heat slightly and bring the mixture to a gentle simmer. You’ll notice the sauce bubbling, allowing all the flavors to meld beautifully—let it simmer for about 5 minutes.
Step 7: Simmer and Thicken
Reduce the heat to low and return the browned sausage to the skillet, allowing it to bathe in the sauce. Cover and let it simmer for an additional 15 minutes. The sauce will thicken, enveloping the sausage and vegetables in tantalizing flavors. Stir occasionally to prevent sticking and ensure even cooking.
Step 8: Serve and Enjoy
Once the sauce has thickened and everything is heated through, it’s time to serve your Italian Sausage Peppers and Onions! Enjoy it over a bed of creamy mashed potatoes, pasta, or in a warm sub sandwich. This dish not only satisfies your dinner cravings but also brings a warm, comforting aroma to your kitchen.
