Step-by-Step Instructions

Step 1: Cook the Pasta

Bring a large pot of generously salted water to a boil.

Cook the fettuccine according to the package directions until al dente.

Before draining, reserve ½ cup of the pasta cooking water.

Drain the pasta and set aside.

Step 2: Prepare the Ingredients

Dice the onion and bell peppers.

Halve the cherry tomatoes.

Mince the garlic.

Slice the sausage into ¼-inch rounds.

Pat the shrimp dry and season generously with the Cajun seasoning.

Step 3: Sear the Shrimp

Heat the butter in a large deep skillet or Dutch oven over medium-high heat.

Add the seasoned shrimp.

Cook for 1–2 minutes per side, just until pink and lightly browned.

Transfer the shrimp to a plate.

Step 4: Brown the Sausage

Using the same skillet, add the sliced sausage.

Cook for 3–4 minutes, allowing the edges to brown and caramelize.

Step 5: Cook the Vegetables

Add the onion, green pepper, and red pepper.

Cook for 4–5 minutes, stirring occasionally until softened.

Stir in the minced garlic and cook for 30 seconds until fragrant.

Add the cherry tomatoes and cook for another 3–4 minutes, allowing them to soften and release their juices.

Step 6: Make the Cream Sauce

Pour the heavy cream into the skillet.

Bring it to a gentle simmer, stirring occasionally.

Cook for 2–3 minutes, until the sauce thickens slightly and coats the back of a spoon.

Remove the skillet from the heat.

Immediately stir in the grated Gruyère cheese and smoked paprika until smooth and fully melted.

Taste and adjust the seasoning if needed.

Step 7: Combine Everything

Add the cooked fettuccine to the skillet.

Return the shrimp along with half of the reserved pasta water.

Toss gently until the pasta is evenly coated.

Add additional pasta water, one tablespoon at a time, if needed to achieve a silky consistency.

Stir in the chopped parsley just before serving.

Step 8: Serve

Serve immediately while hot.

Garnish with extra parsley, freshly cracked black pepper, and additional grated Gruyère if desired.

Recipe Notes & Tips

• Don’t Overcook the Shrimp – Remove them as soon as they turn pink to keep them tender.
• Freshly Grated Cheese Melts Best – Pre-shredded cheese may create a grainy sauce.
• Reserve the Pasta Water – The starch helps emulsify the sauce for a silky finish.
• Simmer the Cream Gently – Avoid boiling to prevent the sauce from separating.
• Cook the Sausage First – The browned bits left behind add incredible flavor to the vegetables.
• Serve Immediately – Cream-based pasta is at its best while freshly made.

A splash of reserved pasta water helps emulsify the sauce, creating a silky coating that clings to every strand of fettuccine. The result is a hearty, comforting pasta dish with the perfect balance of smoky, creamy, and spicy flavors.
