In a large pot or dutch oven, over medium high heat, add the olive oil, smoked sausage, and onion. Cook until the sausage is browned and the onions have softened.
1 tablespoon olive oil, 16 ounces smoked sausage (kielbasa sausage), 1 medium onion
Stir in the garlic and cook for an additional 1 minute or until very fragrant.
3 garlic cloves
Stir the dry penne pasta, diced tomatoes, chicken broth, heavy cream, dried thyme, salt & pepper into the sausage mixture in the pot.
1 box (16 oz) penne pasta, 1 can (14.5 oz) petite diced tomatoes, 3 cups chicken broth, 1 cup heavy cream, 1 teaspoon dried thyme, ½ teaspoon kosher salt, ½ teaspoon black pepper
Bring the mixture to a boil, then reduce the heat to a simmer (medium low heat), stirring occasionally to prevent the pasta from sticking. Allow it to simmer for about 15-20 minutes or until the pasta is al dente or softened to your liking and the excess liquid is absorbed.
Add the shredded cheddar cheese and parmesan cheese, and stir until the cheese is melted and combined.
1 cup shredded cheddar cheese, 1/4 cup shredded parmesan cheese
Serve the pasta with chopped parsley, if wanted, and enjoy!
