Holly’s Sausage Spaghetti Highlights
- Flavor: Juicy and savory Italian sausage and rich, robust marinara are a perfect pair in this recipe.
- Difficulty: A jar of marinara makes for quick and easy prep.
- Swaps: Use ground beef, ground turkey, or ground chicken instead of sausage.
- Freezing: Cool the sauce and freeze in bags or containers for up to 3 months. Thaw in the fridge or warm on the stove when ready to use!
- Serving suggestions: Serve Italian sausage spaghetti with thick slices of homemade garlic toast to soak up all that tasty sauce.
Spaghetti Symphony of Ingredients
Sausage: Italian links contain garlic, fennel, and red pepper flakes that give them a mildly spicy, aromatic flavor. Make a homemade blend and adjust the seasonings any way you like.
Pasta: Regular spaghetti, bucatini, or any heavier pasta shape works best in this recipe.
Marinara: Choose your favorite brand of marinara sauce or make it homemade and freeze it for future meals.
Switch It Up: Add sliced mushrooms or yellow onions, sliced black olives, or some shredded carrots and zucchini for a sweeter sauce and a pop of nutrition.
How to Make Italian Sausage Spaghetti
- Fry: Brown sausages in oil and then cut (full recipe below).
- Mix: In the same pan, stir sausage pieces with the remaining ingredients. Simmer.
- Toss: Cook spaghetti and then toss pasta with the sauce.
Garnish with parmesan cheese before serving.
Pasta Pointers
- Save a little pasta water in case the sauce needs to be thickened up a little.
- Cook pasta to al dente since it will cook a little bit more when it’s added to the pot in Step 5.
Second-Day Spaghetti
- Keep leftover Italian sausage spaghetti in a covered container in the refrigerator for up to 4 days. Reheat portions in the microwave or on the stovetop and adjust the seasonings.
- Leftovers can be baked casserole-style with a topping of seasoned breadcrumbs and freshly grated Parmesan cheese.
- Italian sausage and the sauce can be frozen together in zippered bags for up to one month. Pasta doesn’t thaw well, so it’s advised to start with fresh pasta.
