Ingredients
- Olive Oil: Provides a flavorful, heart-healthy fat base for sautéing the kielbasa and vegetables evenly.
- Kielbasa: 13 ounces of smoked Polish sausage, sliced into ¼-inch rounds for crisp edges and smoky richness.
- Yellow Onion: ¾ cup diced onion adds sweetness and depth to the dish as it softens during cooking.
- Red Bell Pepper: ¾ cup diced for a fresh pop of color and subtle sweetness that complements the sausage.
- Minced Garlic: One tablespoon of garlic lends an aromatic, savory aroma that enhances overall taste.
- Petite Diced Tomatoes: 14.5 ounces, undrained, supply bright acidity and moisture to create a flavorful sauce.
- Chicken Stock: Two cups act as the cooking liquid, infusing the pasta with savory flavors while it simmers.
- Half & Half: Half a cup adds creamy richness, balancing the acidity of the tomatoes with smooth texture.
- Salt: Half a teaspoon to season and enhance all the dish’s flavors evenly.
- Black Pepper: A quarter teaspoon provides gentle heat and earthy undertones.
- Rotini Pasta: Half a pound pasta that holds sauce well with its spiral shape, absorbing flavors beautifully.
- Sharp Cheddar Cheese: 1½ cups shredded for a creamy, tangy finish that melts to perfection into the dish.
- Green Onions: Two tablespoons chopped and sprinkled on top for a fresh, mild bite and vibrant color contrast.
Instructions
- Heat Olive Oil and Brown the Kielbasa
-
In a large 12-inch deep skillet over medium-high heat, warm the olive oil until shimmering, then add the sliced kielbasa. Cook for 2-3 minutes until the edges begin to brown and crisp, which intensifies the sausage’s smoky flavor and adds a pleasant texture.
- Sauté Onions, Bell Peppers, and Garlic
-
Once the kielbasa edges are nicely browned, stir in diced yellow onions, red bell peppers, and minced garlic. Cook for about 3-4 minutes until the vegetables soften and become translucent, building a flavorful aromatic base.
- Add Tomatoes, Stock, Half & Half, and Pasta
-
Pour petite diced tomatoes (with juices), chicken stock, and half & half into the skillet. Season with salt and black pepper. Add the rotini pasta and stir everything to combine evenly, ensuring the pasta is submerged as much as possible for even cooking.
- Simmer Until Pasta is Al Dente
-
Reduce heat to medium-low and let the pasta cook uncovered for 12-14 minutes, stirring frequently. This allows the pasta to absorb flavor and liquid, cooking it to just tender yet firm (al dente) while the sauce thickens beautifully.
- Incorporate Sharp Cheddar Cheese
-
Remove the skillet from heat and immediately stir in the shredded sharp cheddar cheese. Stir until fully melted and the sauce becomes creamy, creating a luscious coating for the pasta and sausage.
- Garnish and Serve
-
Sprinkle chopped green onions over the top to add freshness and a mild bite that contrasts the richness of the dish. Serve hot, straight from the skillet for best flavor and texture.
- Ensure the pan and oil are fully heated before adding kielbasa to achieve nice browning and flavor development.
- If the kielbasa releases excess grease, blot it with paper towels to keep the dish from becoming too oily.
- Frequently stir the pasta while simmering to prevent sticking and even cooking.
- Adjust sauce consistency by adding more warm chicken stock if too thick, or simmer longer to thicken if too thin.
- Remove from heat before adding cheese to help it melt smoothly without clumping.
Storage Tips
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave with a splash of chicken stock to loosen the sauce.
Serving Suggestions
This hearty pasta pairs wonderfully with a side of crisp green salad or steamed vegetables for added freshness. Serve with crusty bread to soak up any extra sauce and complete your meal.
- For best flavor, cook kielbasa in batches if your skillet is crowded to ensure even browning.
- Use warm chicken stock during cooking to maintain consistent temperature and speed up pasta cooking time.
- Choose sharp cheddar cheese with good melting properties for a creamy, rich sauce texture.
FAQs
- Can I use other types of sausage instead of kielbasa?
-
Yes, smoked sausages like Andouille or chorizo work well, though the flavor profile will change slightly.
- What pasta can I substitute for rotini?

Penne, fusilli, or shells are great alternatives as they hold sauce similarly to rotini.

- Can I make this recipe vegan or dairy-free?
-
Replace half & half with coconut cream or plant-based milk and use vegan cheese or nutritional yeast.
- How can I make this recipe spicier?
-
Add red pepper flakes when sautéing the vegetables or use a spicy kielbasa variety.
- Can I prepare this recipe in advance?
