Ingredients

- 12 ounces spaghetti
- 1 pound Italian sausage, casings removed
- 1 1/2 cups tomato sauce
- 2 cloves garlic, minced
- 1/2 teaspoon red pepper flakes
- 2 tablespoons olive oil
- Salt, to taste
- Freshly ground black pepper, to taste
- 1/4 cup fresh parsley, chopped
- 1/4 cup grated Parmesan cheese
- 1/2 small onion, finely chopped

Instructions
This dish is all about making every bite count—with simple ingredients coming together to create something rich and satisfying. You’ll mix savory sausage with a pinch of heat, fresh garlic, and a cozy tomato sauce, all hugging the spaghetti perfectly. Let’s get cooking!
- Boil the spaghetti: Bring a large pot of salted water to a boil and cook the spaghetti according to the package instructions until al dente; then drain, reserving a cup of pasta water just in case you want to loosen the sauce later.
- Sauté the aromatics: In a large skillet, heat the olive oil over medium heat, then add the finely chopped onion and minced garlic, cooking until softened and fragrant, about 3-4 minutes.
- Brown the sausage: Add the Italian sausage to the skillet, breaking it up with a spoon; cook it through until nicely browned, about 6-8 minutes, making sure there’s no pink left.
- Spice it up: Sprinkle in the red pepper flakes and season with salt and freshly ground black pepper to taste, stirring well to spread the flavor evenly.
- Add the tomato sauce: Pour in the tomato sauce, give everything a good stir, and let it simmer gently for about 10 minutes so the flavors can meld together.
- Toss the pasta: Add the cooked spaghetti into the skillet with the sauce and sausage, tossing everything to coat the noodles evenly; add a splash of reserved pasta water if the sauce feels thick.
- Finish with parsley and cheese: Stir in the chopped fresh parsley, then sprinkle the grated Parmesan cheese over the top just before serving for that authentic touch.
How to Store Spaghetti With Italian Sausage
Let any leftovers cool completely before transferring them to an airtight container. Store in the refrigerator for up to 3 days, and reheat gently on the stove or in the microwave with a splash of water to keep the sauce from drying out. For longer storage, freeze in a suitable container for up to 2 months—just thaw overnight in the fridge before reheating. Buon appetito!
Tweaks and Additions
Here are some simple ways to boost the flavors or add a little twist to this classic spaghetti with Italian sausage recipe. Each tweak keeps things easygoing and flexible—just like making pasta with an old friend.
- Swap Italian sausage for ground beef or turkey: If Italian sausage isn’t on hand, ground beef or turkey makes a great stand-in and keeps the dish hearty and comforting.
- Add a splash of red wine: Pour a little red wine into the skillet after browning the sausage to deepen the flavor and add a subtle richness—it’ll cook down nicely with the sauce.
- Include chopped bell peppers: Toss in some diced red or green bell peppers when sautéing the onion and garlic for a touch of sweetness and extra crunch.
- Use fresh basil along with parsley: Adding fresh basil toward the end brightens up the sauce with its aromatic, slightly sweet taste—perfect for that authentic Italian note.
- Mix in a pinch of smoked paprika: Stir in smoked paprika with the red pepper flakes to add a warm, smoky depth while keeping just the right hint of heat.
- Finish with a drizzle of quality extra virgin olive oil: A light drizzle over the plated pasta just before serving lifts the flavors and adds a silky texture.
- Top with toasted pine nuts: Sprinkle toasted pine nuts on top for a delightful crunch and a subtle nutty flavor that complements the sausage.
- Stir in a spoonful of ricotta cheese: Add a dollop of creamy ricotta right before serving to mellow out the sauce and make each bite extra comforting.
