Ingredients

1 lb (450 g) Italian sausage, sliced or crumbled

1 medium onion, diced

3 cloves garlic, minced

1 lb (450 g) penne pasta (or preferred pasta shape)

3 cups (710 ml) chicken broth

1 can (14.5 oz / 411 g) diced tomatoes

1 tablespoon tomato paste

2 cups (200 g) shredded mozzarella cheese

1/2 cup (50 g) grated Parmesan cheese

1 teaspoon dried Italian herbs

Salt and black pepper, to taste

2 cups fresh spinach or 1 cup cherry tomatoes

Instructions

Prepare Ingredients: Slice or crumble the sausage, dice the onion, mince the garlic, and measure out the pasta and liquids.

Brown the Sausage: Heat a large skillet or Dutch oven over medium-high heat with a small splash of oil. Cook the sausage until browned and slightly crispy.

Cook Aromatics: Add the diced onion and garlic to the skillet. Cook for 2–3 minutes until softened and fragrant.

Add Pasta and Liquids: Stir in the penne pasta, chicken broth, diced tomatoes, tomato paste, and dried Italian herbs. Mix well.

Simmer: Bring the mixture to a boil, then reduce heat to low. Simmer uncovered for 12–15 minutes, stirring occasionally, until the pasta is al dente and most of the liquid is absorbed.

Add the Cheese: Stir in the mozzarella and Parmesan cheese until melted and creamy.

Finish the Dish: Taste and adjust seasoning with salt and pepper. Stir in spinach and allow it to wilt for about 1 minute, or add cherry tomatoes for freshness.

Serve: Spoon the cheesy sausage pasta into bowls and serve warm.

Notes

Use freshly shredded mozzarella for the best melt and creamy texture.

If the sauce becomes too thick, stir in a small splash of broth or milk.

For extra heat, add red pepper flakes or spicy Italian sausage.

This dish stores well in the refrigerator for 3–4 days in an airtight container.
