Bring a large pot of salted water to a boil. Add the rigatoni pasta (or pasta of your choice) and cook according to package instructions until al dente. Drain the cooked pasta and set aside.
While the pasta is cooking, slice the kielbasa sausage into bite-sized pieces. Finely chop the garlic and onion.
In a large skillet or pan, heat a bit of oil over medium heat. Add the sliced kielbasa sausage and cook until lightly browned and slightly crispy, about 5-7 minutes. Remove the cooked kielbasa from the skillet and set aside. Leave any drippings in the skillet.
In the same skillet with the kielbasa drippings, add the chopped garlic and onion. Sauté until fragrant, about 2 minutes.
Pour the jar of marinara sauce into the skillet with the sautéed aromatics. Stir to combine, then add the beef powder or beef cube (if using) to enhance the flavor. Season with a touch of sugar to balance the acidity of the sauce. Let the sauce simmer for about 5-7 minutes to allow the flavors to meld together.
Once the sauce has simmered and thickened slightly, pour in the heavy cream, stirring until well combined. Return the cooked kielbasa to the skillet, stirring to incorporate it into the sauce. Allow the sauce to simmer for an additional 2-3 minutes, or until heated through.
Add the cooked rigatoni pasta to the skillet with the creamy kielbasa sauce. Toss everything together until the pasta is evenly coated with the sauce.
Divide the creamy kielbasa pasta among serving plates. Garnish with grated Parmesan cheese and chopped parsley for added flavor and freshness.
Serve immediately and enjoy your Creamy Kielbasa Pasta while it's hot and comforting!
Notes
Opt for high-quality kielbasa sausage, fresh mushrooms, and flavorful marinara sauce to ensure the best taste in your dish.
Cook the pasta just until al dente to ensure it maintains its texture and doesn't become mushy when mixed with the sauce.
Be cautious when adding heavy cream to the sauce, as too much can make it overly rich. Start with a small amount and adjust to your preference.
