Sausage Pasta Ingredients

This recipe uses simple, flexible ingredients. If you don’t have something exact, substitute with the suggested alternatives or whatever you have on hand.

• Sausage: Smoked Polish kielbasa works beautifully for its smoky, slightly spicy flavor. You can also use spicy Italian sausage, or any sausage you prefer.
• Onion and fresh minced garlic (or garlic paste). Frozen chopped onion and garlic are fine in a pinch.
• Cajun seasoning — adjust amount to control heat.
• Chopped tomatoes or crushed tomatoes from a can.
• Chicken stock or low-sodium chicken broth.
• Dried pasta: Rigatoni, penne or fusilli are good choices.
• Mascarpone and grated Parmesan. Mascarpone can be replaced with cream cheese or ricotta if needed.
• Fresh basil for garnish or dried Italian herbs if you don’t have fresh.

1. Mist a large pot with a little olive oil or add 1 tbsp oil, then pan-fry the sliced kielbasa over medium-high heat until it starts to color and crisp at the edges. If using fresh sausages, brown them until firm enough to slice, or remove the meat from the casings and crumble it in the pan.

   

2. Lower the heat and add a diced onion, 2 tsp Cajun seasoning and ½ tsp salt. Cook, stirring, for about 5–7 minutes until the onion softens.

   

3. Stir in 2 minced garlic cloves and cook briefly until fragrant. Then add a 14 oz (400g) can of chopped or crushed tomatoes and stir to combine.

   

4. Pour in 4 cups (960 ml) hot chicken stock and bring the mixture to a rolling simmer.

   

5. Stir in 14 oz (400g) dried pasta, reduce the heat to a simmer and partially cover the pot. Cook, stirring occasionally, until the pasta is cooked through but still al dente. Because the pasta cooks in liquid, plan for roughly 1½ times the usual packet cooking time and keep stirring to prevent sticking.

   

6. Remove the pot from the heat and stir in 3 tbsp full-fat mascarpone (or cream cheese) until melted and incorporated. Add 4 tbsp grated Parmesan and mix well.

   

7. Taste and adjust seasoning with salt, freshly ground pepper and optional chili flakes. Serve topped with chopped fresh basil and extra Parmesan.

   

Recipe Tips

A note on sausages: Fresh sausages can be pan-fried whole until browned and then sliced, or remove the meat from the casings and crumble it into the pan. Smoked kielbasa gives a lovely depth, but spicy Italian sausage works just as well.

One-pot pasta: Cooking the pasta in the sauce takes a little longer than boiling it separately. Stir frequently to keep the pasta from sticking and expect a longer cook time than the packet suggests.

Make it lightweight: For a slimming-friendly version use lean sausages and swap mascarpone for light cream cheese or a low-fat soft cheese to reduce calories without losing creaminess.

Storing and reheating: Store leftovers in the fridge for up to two days. Reheat gently in a saucepan, adding a splash of hot water or milk if the sauce has thickened. This dish is not ideal for freezing.

Vegetarian option: Use vegetarian sausages, cooked separately if needed, and stir them in at the end.
