Ingredients You’ll Need
- Pasta noodles (12 oz) – penne, rigatoni, or fettuccine work best since they hold creamy sauces.
- Kielbasa sausage (12 oz) – slice into bite-sized rounds. The smoky flavor is the star here.
- Red bell pepper – adds sweetness and color.
- Green bell pepper – adds a slight bite and balances the sweetness.
- Yellow or white onion – sautéed until golden for depth.
- Heavy whipping cream (1 cup) – the base of your sauce.
- Mozzarella cheese (1 cup, shredded) – for gooey meltiness.
- Parmesan cheese (½ cup, grated) – for sharpness and depth.
- Pasta water (½ cup, reserved) – helps create a silky sauce.
- Seasonings of choice – I recommend salt, black pepper, garlic powder, smoked paprika, Italian herbs, and a pinch of red chili flakes.
- Olive oil or butter – for sautéing.
Step-by-Step Instructions
1. Cook the Pasta
Bring a large pot of salted water to a boil. Add pasta and cook until al dente (a slight bite in the center). Reserve ½ cup of pasta water, then drain and set aside. 💡 Tip: Always salt your pasta water like the sea — it’s the only chance to season the noodles themselves.
2. Sear the Sausage
In a large skillet over medium heat, add a drizzle of olive oil. Sauté the kielbasa slices until golden brown on both sides, about 4–5 minutes. Remove and set aside.
3. Cook the Veggies
In the same skillet, add a little more oil if needed. Toss in sliced onions and bell peppers. Cook until softened and slightly caramelized, around 6–8 minutes. This adds sweetness and depth to the sauce.
4. Make the Cream Sauce
Lower the heat. Pour in heavy cream, stirring gently. Add seasonings — salt, pepper, garlic powder, smoked paprika, Italian herbs, and a pinch of chili flakes for heat. Slowly stir in the mozzarella and parmesan until melted and creamy. Add reserved pasta water a little at a time until the sauce is silky and coats the back of a spoon.
5. Bring It All Together
Add back the sausage, then toss in the drained pasta. Stir until every noodle is coated in the cheesy cream sauce. Taste and adjust seasoning if needed.
6. Serve & Garnish
Plate the pasta while it’s hot. Top with extra parmesan, a sprinkle of chili flakes, and maybe fresh parsley for color. Serve with garlic bread or a side salad for a full meal.
Variations & Add-Ins
Protein swaps: While kielbasa sausage brings a smoky, savory flavor, you can easily switch it up. Grilled chicken breast adds a leaner option while still keeping the dish hearty. Shrimp makes it lighter and slightly sweet, pairing beautifully with the creamy sauce. Italian sausage gives you extra herbs and spice for a bolder flavor. For a vegetarian twist, try using plant-based sausage or even chickpeas for added protein.
Extra veggies: This dish is versatile and a great way to sneak in more vegetables. Mushrooms add an earthy depth, spinach wilts into the sauce and boosts the nutrition, and broccoli provides a fresh crunch that balances the creaminess. You could also try zucchini, cherry tomatoes, or roasted eggplant for more Mediterranean flair.
Spice it up: If you like a little kick, don’t hold back on the heat. Add cayenne pepper, hot paprika, or red chili flakes directly into the sauce for warmth throughout. For an even spicier edge, stir in a spoonful of sriracha or a dash of hot sauce. You can also swap smoked paprika for chipotle powder for a smoky-spicy profile.
Lighter version: Heavy cream creates a rich, thick sauce, but you can make a lighter version if you prefer. Half-and-half works as a substitute, though the sauce won’t be quite as thick. You could also use evaporated milk or even a mix of milk with a little cream cheese to add body without as much fat. For dairy-free eaters, try full-fat coconut milk or a cashew cream base.
Storage Tips
Refrigerate: Allow the pasta to cool completely before transferring it to an airtight container. It will stay fresh in the fridge for up to 3 days. Keeping the pasta and sauce separate (if possible) helps prevent the noodles from soaking up too much liquid overnight.
Reheat: The creamy sauce tends to thicken after sitting, so when reheating, add a splash of milk, cream, or even chicken broth to loosen it back up. Reheat on the stovetop over medium-low heat, stirring frequently to prevent the sauce from splitting. If using the microwave, heat in 30-second intervals, stirring between each round.
Freeze: Cream-based sauces don’t freeze well because they tend to separate and turn grainy after thawing. If you want to freeze, the best method is to cook the pasta and freeze it separately from the sauce. You can freeze the sausage and sautéed peppers/onions, then make a fresh cream sauce when ready to serve.
