Creamy One-Pot Italian Sausage Shells and Cheese

Ingredients

Below are the ingredients that build the flavor for this one-pot meal, along with helpful substitution ideas. See the recipe card at the bottom for exact measurements and cooking times.

• Olive oil – for sautéing the aromatics and browning the sausage.
• Onion – diced; provides sweetness and depth. Yellow or white onion both work well.
• Garlic cloves – minced for aromatic flavor. Fresh garlic gives the best results; jarred minced garlic can be used in a pinch.
• Loose Italian sausage – use hot for a spicy kick or mild if you prefer less heat. Avoid packaged links unless you remove the casings; the loose sausage is easiest to brown and break up.
• Small pasta shells – shells hold sauce well, but other small shapes like macaroni or cavatappi can substitute.
• Chicken broth – adds savory liquid and helps cook the pasta. Vegetable broth is a good substitute for a milder flavor.
• Tomato sauce – adds acidity and color. Crushed tomatoes can work but may change the texture slightly.
• Italian seasoning – a blend of dried herbs that rounds out the sauce. Use your favorite store-bought mix or a homemade blend of oregano, basil, thyme, and rosemary.
• Cream cheese – cubed into the hot pasta to melt into a creamy base.
• Parmesan cheese – freshly grated for sharpness and umami.
• Mozzarella cheese – shredded for melty, gooey texture.

Instructions

1. Heat the olive oil in a large pot or Dutch oven over medium heat.
2. Add the diced onion and sauté for 3–4 minutes until it begins to soften. Stir in the minced garlic and cook for an additional minute until fragrant.
3. Add the loose Italian sausage to the pot. Break it up with a spoon and cook 7–9 minutes until browned and cooked through.
4. Pour in the small pasta shells, chicken broth, tomato sauce, and Italian seasoning. Stir to combine, scraping any browned bits from the bottom of the pot.
5. Bring the mixture to a gentle simmer, then cover, reduce the heat to low, and cook for 15–20 minutes, or until the pasta is tender and most of the liquid has been absorbed. Stir occasionally to prevent sticking.
6. Remove the lid and add the cubed cream cheese, grated Parmesan, and shredded mozzarella. Stir until the cheeses melt into a creamy sauce, cooking for another 3–4 minutes. Taste and season with salt and freshly ground black pepper as needed.
7. Serve immediately, garnished with chopped fresh basil or parsley if desired.

Tip: If the sauce becomes too thick, stir in a splash of extra broth or a tablespoon of milk to loosen it. For a richer finish, add a knob of butter at the end.

What to serve with it

This hearty shells-and-cheese pairs beautifully with a crisp salad or garlic-forward bread. Try a simple green salad with a bright vinaigrette to balance the richness, or serve with garlic bread, garlic knots, or cheesy garlic bread nachos for a crowd-pleasing combination. A Caesar or Italian-style salad complements the flavors nicely.
