Why You’ll Love Cajun Shrimp Pasta
- Meal prep friendly: flavors deepen after a day or two, and the sauce reheats well.
- Simple yet elegant: minimal active time produces a hearty, restaurant-style pasta.
- Customizable: swap proteins, add vegetables, or adapt for gluten-free and keto diets.
Key Ingredients

(Full ingredient amounts are listed in the recipe card below.)
- Andouille sausage – the smoky, spicy backbone. Substitute smoked kielbasa or another smoked sausage if needed.
- Shrimp – peeled and deveined large shrimp work best. Thaw frozen shrimp completely before cooking.
- Cajun seasoning – use a store blend or make your own to control heat and salt.
- Onion, celery, red bell pepper – the Cajun “holy trinity” that builds the sauce base.
- Diced tomatoes and tomato paste – paste sautéd briefly adds depth; canned diced tomatoes give body and acidity.
- Heavy cream and parmesan – create a rich, silky sauce; grate fresh parmesan for best melting and flavor.
- Lemon juice and parsley – brighten the sauce and finish the dish.
- Pasta – choose a sturdy short pasta like penne or casarecce so the sauce clings to each bite.
Substitutions and Variations
- Swap pasta shapes: rigatoni, fusilli, fettuccine, or linguine will all work.
- Try grits instead of pasta for Cajun shrimp and grits.
- Change the protein: chicken, scallops, salmon, or tofu are great alternatives.
- Make it keto with zucchini noodles or spaghetti squash; use gluten-free pasta for a GF version.
- Turn it into a bake: top with mozzarella or cheddar and bake at 350°F until bubbly.
- Adjust heat with jalapeños, red pepper flakes, or extra cayenne.
- For a lighter dish, reduce or omit the heavy cream and cheese.
How to Make Cajun Shrimp Sausage Pasta

Step 1: Boil the pasta. Bring a large pot of water to a boil (adding a bit of bouillon is optional). Cook pasta until al dente, reserve 1 cup of pasta water, then drain.

Step 2: Season the shrimp with Cajun seasoning, salt, and pepper. Set aside.

Step 3: Cook the sausage. Heat olive oil in a large skillet over medium heat and brown the andouille on both sides, about 5–7 minutes. Remove and set aside.

Step 4: Cook the shrimp briefly in the same pan for 2–3 minutes until pink and just cooked through. Remove and combine with the sausage.

Step 5: Sauté the aromatics. In the pan with the fond and a little oil, cook onion, bell pepper, and celery until softened and starting to brown, about 5–7 minutes. Add garlic and cook another 2 minutes.

Step 6: Add tomato paste, garlic powder, onion powder, and remaining Cajun seasoning. Cook 3–4 minutes to develop flavor, then deglaze with chicken broth and add diced tomatoes, scraping up browned bits.

- Stir in heavy cream and simmer on low until the sauce thickens, about 5–7 minutes.
- Add spinach and parmesan, stirring until the spinach wilts and cheese melts. Add 1/2 cup pasta water to thin the sauce; use up to the reserved cup if needed for a looser sauce.
- Taste and adjust seasoning, then toss in cooked pasta and top with shrimp, sausage, and fresh parsley to serve.
Pro Tips for Making Creamy Cajun Shrimp Pasta
- For meal prep, store sauce and pasta separately to prevent soggy noodles.
- Always reserve pasta water—it helps the sauce cling to the pasta and smooths the texture.
- Sauté the aromatics and tomato paste slowly to build deeper flavor.
- Remove shrimp as soon as it turns pink and curls into a loose “C” to avoid overcooking.
- Different Cajun blends vary in salt and heat—adjust seasoning as you cook.
FAQs
A crisp white like Sauvignon Blanc or Pinot Grigio pairs well. The acidity cuts through the cream and complements the spices.
Keep sides simple and fresh: crusty bread to sop the sauce, a light green salad with vinaigrette, roasted vegetables, or garlic bread.
Leftovers keep 3–4 days in an airtight container in the refrigerator.
