How to Make Pasta with Sausage, Peppers, and Onions Recipe
Step 1: Sauté the Vegetables
Start by heating the olive oil in a large skillet over medium-high heat. Toss in the sliced onion, bell pepper, mushrooms, and minced garlic. Season with a pinch of salt and pepper to coax out their natural sweetness. Let them cook for around 7 minutes, stirring occasionally until they become tender and lightly caramelized. Once ready, remove the vegetables from the skillet and set them aside to keep their vibrant flavors intact for the next step.
Step 2: Cook the Sausage
Next, add your Italian sausage links, either sliced or crumbled, to the same skillet. Allow the sausage to brown nicely, stirring frequently. That delicious caramelization forms the backbone of the dish’s deep flavor and makes the sauce irresistibly hearty.
Step 3: Deglaze the Pan
Pour in the white wine or chicken broth to deglaze the pan, scraping up all the browned bits stuck to the bottom. This step is pure magic, as it incorporates those intense flavors back into the sauce. Let it simmer for a minute or two to reduce slightly.
Step 4: Simmer the Sauce
Add the canned diced tomatoes, season again with salt and pepper, then return the sautéed vegetables to the skillet. Bring everything to a boil before turning down the heat and letting it simmer gently for 15 to 20 minutes. This simmering melds all the ingredients together, developing a sauce that’s bursting with bold, balanced flavor.
Step 5: Cook the Pasta
While the sauce simmers, cook your fresh fettuccine pasta according to the package instructions until it reaches al dente—tender but still with a slight bite. Drain the pasta and get ready to bring it all together.
Step 6: Combine and Serve
Finally, toss the cooked pasta directly into your sauce, making sure every noodle is coated beautifully. Serve piping hot with a generous sprinkle of grated Romano cheese and a pinch of crushed red pepper flakes if you love a bit of heat. This final assembly is where the magic comes alive, delivering a dish that’s as colorful as it is delicious.

FAQs
