Ingredients
These simple ingredients come together to create a symphony of Italian flavors. Choose high-quality components for the best results.
- 1 lb Italian sausage (mild or hot, depending on preference. You can also use ground pork or turkey with Italian seasoning)
- 1 yellow onion, diced (sweet or white onion also works)
- 1 tbs minced garlic (freshly minced garlic offers the best flavor)
- 4 cups chicken broth (or vegetable broth for a lighter taste)
- 1 tsp salt (adjust to taste, especially if using salted broth)
- ½ tsp pepper (freshly ground black pepper is always recommended)
- 24 oz marinara sauce, (I used a jar for convenience; feel free to use your favorite homemade marinara)
- 16 oz small shell pasta (or medium shells, penne, or cavatappi)
- ½ cup heavy cream (for a rich, creamy texture)
- ½ cup parmesan cheese (freshly grated is always superior)
Instructions
Follow these straightforward steps to create a delicious and easy one-pot Italian Shells with Sausage meal!
- 1. Brown the Sausage and Sauté the Onion: In a large pot or Dutch oven, add the Italian sausage and diced yellow onion. Place over medium heat. Using a meat masher or spatula, break up the sausage into small pieces and cook thoroughly until it’s nicely browned and the onion is translucent and softened. This usually takes about 7-10 minutes.
- 2. Deglaze and Simmer with Pasta: Once the sausage is cooked, carefully drain any excess grease from the pot. This step is crucial for preventing a greasy final dish. Return the pot to the stove, then add the minced garlic and cook for about 30 seconds until fragrant. Pour in the chicken broth, salt, pepper, and marinara sauce. Stir everything together well and bring the mixture to a gentle simmer. Once simmering, stir in the small shell pasta. Cover the pot and let it simmer for approximately 15 minutes, or until the pasta is tender. Make sure to stir the pasta often, every 2-3 minutes, to prevent it from sticking to the bottom of the pot and to ensure even cooking. The pasta will absorb most of the liquid as it cooks.
- 3. Finish with Cream and Cheese: Once the pasta is tender and most of the liquid has been absorbed, remove the pot from the heat. Stir in the heavy cream and grated Parmesan cheese until fully combined and the sauce becomes rich and creamy. Serve immediately, garnished with a sprinkle of fresh parsley or additional Parmesan cheese, and enjoy your hearty one-pot meal!

Pro Tips for Perfect Italian Shells with Sausage
Achieve restaurant-quality results with these helpful tips:
- Choose Your Sausage Wisely: Italian sausage comes in mild, sweet, and hot varieties. Select the one that best suits your palate. For an extra kick, opt for hot Italian sausage. You can also mix half mild and half hot.
- Don’t Skimp on Draining: After browning the sausage, it’s important to drain off any excess fat. This prevents your dish from becoming greasy and heavy, ensuring a clean, rich flavor.
- Stir Regularly: While the pasta simmers, stir the pot every few minutes. This prevents the shells from sticking to the bottom of the pot and helps them cook evenly in the sauce.
- Perfect Pasta Al Dente: Keep an eye on the pasta as it simmers. You want it cooked “al dente” – tender but still with a slight bite. Overcooked pasta can become mushy.
- Fresh Garlic is Key: While jarred minced garlic can work in a pinch, fresh garlic will significantly enhance the aroma and depth of flavor in your dish.
- Quality Marinara Matters: A good quality marinara sauce will lay the foundation for a delicious dish. Choose a brand you love, or better yet, use homemade marinara if you have it.
- Avoid Boiling Cream: Once you add the heavy cream and Parmesan, remove the pot from direct heat or ensure the heat is very low. Boiling cream can sometimes cause it to separate.
Variations & Customizations
This Italian Shells with Sausage recipe is incredibly versatile! Feel free to experiment with these ideas to make it your own:
Protein Alternatives:
- Ground Beef or Turkey: Not a fan of sausage? Substitute with 1 lb of ground beef or turkey, seasoned with a teaspoon of Italian seasoning, garlic powder, and onion powder while browning.
- Chicken: Diced chicken breast or thigh can be used. Brown it before adding the onion and garlic.
- Vegetarian Option: Use plant-based Italian sausage, or load up on extra vegetables like sliced mushrooms, zucchini, or bell peppers for a meat-free version.
Adding Vegetables:
- Spinach: Stir in a few handfuls of fresh spinach at the very end, just before adding the cream and cheese. The residual heat will wilt it perfectly.
- Bell Peppers: Add diced bell peppers (red, yellow, or green) along with the onion for extra color and flavor.
- Zucchini: Diced zucchini can be added during the last 5-7 minutes of pasta simmering.
- Mushrooms: Sauté sliced mushrooms with the onion and sausage for an earthy depth.
Cheese Please!
- Ricotta Cheese: For an even creamier, lasagna-like texture, stir in ½ cup of ricotta cheese with the heavy cream and Parmesan.
- Mozzarella: If you love a cheesy pull, sprinkle some shredded mozzarella on top after stirring in the cream and let it melt for a few minutes with the lid on, or transfer to an oven-safe dish and broil briefly.
- Asiago or Provolone: Experiment with other Italian cheeses for different flavor profiles.
Spice it Up:
- If you prefer a spicier dish, use hot Italian sausage or add a pinch of red pepper flakes with the garlic.
Pasta Power:
- While shells are traditional, feel free to use other pasta shapes like penne, rigatoni, cavatappi, or even orecchiette. Just ensure the cooking time is adjusted according to package directions.
Serving Suggestions
This hearty Italian Shells with Sausage is a complete meal on its own, but pairing it with a few simple sides can elevate your dining experience:
- Garlic Bread or Breadsticks: Perfect for soaking up every last drop of the delicious creamy sauce.
- Side Salad: A fresh green salad with a light vinaigrette offers a refreshing contrast to the richness of the pasta.
- Roasted Vegetables: Roasted asparagus, broccoli, or green beans make a great healthy accompaniment.
- Wine Pairing: A medium-bodied red wine like a Chianti, Merlot, or Pinot Noir would beautifully complement the savory notes of the sausage and marinara.
Storage and Reheating
Got leftovers? Lucky you! This Italian Shells with Sausage dish tastes even better the next day.
- Refrigeration: Store any leftover pasta in an airtight container in the refrigerator for up to 3-4 days.
- Freezing: This dish freezes reasonably well. Transfer cooled leftovers to a freezer-safe container and freeze for up to 2-3 months. Thaw overnight in the refrigerator before reheating.
- Reheating:
- Stovetop: For best results, reheat on the stovetop over medium-low heat, adding a splash of chicken broth or milk to help loosen the sauce and restore creaminess. Stir occasionally until heated through.
- Microwave: For a quick reheat, portion into microwave-safe dishes and heat in 1-minute intervals, stirring in between, until hot. You might need to add a tablespoon of liquid to keep it from drying out.
