Cajun Spaghetti Recipe — Creamy Louisiana-Style Pasta
Creamy Cajun spaghetti with bold Louisiana spices, bell peppers, and a smoky Parmesan cream sauce. The dish I first ate at a restaurant in Dubai and had to recreate the same week. Ready in 30 minutes — add chicken, shrimp, or keep it vegetarian. Fully halal-friendly.

Ingredients
- 150 g Spaghetti or substitute penne, fettuccine, or linguine
- 1 tablespoon Olive Oil
- 1 teaspoon fresh garlic finely minced
- 1 cup Onion finely diced (Medium Size )
- 1 Medium Size Bell pepper (green + yellow), diced use one of each for color
- 1 Celery stalk, finely chopped optional, completes the holy trinity
- 2 teaspoons Tomato paste
- 1 tablespoon Cajun seasoning homemade or store-bought (adjust for heat)
- ⅓ teaspoon Salt taste before adding, Cajun blends vary in sodium
- ⅓ teaspoon Black Pepper
- 1 tablespoon Pasta water or Veg Broth/Chicken Broth
- 0.5 cup Heavy cream
- 0.3 cup Parmesan cheese, freshly grated Halal-certified Parmigiano Reggiano
- 2 tablespoon fresh parsley or cilantro for garnish
Instructions
Cook spaghetti and reserve pasta water:
- Bring a large pot of salted water to a rolling boil. Add150 grams spaghetti — or substitute penne, fettuccine, or linguine and cook for 8–9 minutes until al dente — firm to the bite, not soft. Before draining, scoop out 0.5 cups reserved pasta water — starchy, do not substitute with tap water and set aside — this starchy water is essential to the sauce. Drain the pasta and toss lightly with a drizzle of olive oil to prevent clumping. Set aside.
Sauté the aromatics:
- Heat 1 tablespoons olive oil in a wide skillet over medium heat. Add 1 teaspoons fresh garlic, finely minced and sauté for 30–6 minutes until fragrant — do not let it brown. Add 1 cups onion, finely diced and cook for 3–4 minutes until soft and translucent. If using 1 celery stalk, finely chopped — optional, completes the holy trinity, add it with the onion — it takes the same time to soften. Add 1 bell pepper (green + yellow), diced — use one of each for color and cook for 2 minutes until slightly softened but still with texture.
Build the Cajun sauce:
- Add 2 teaspoons tomato paste to the pan and stir to coat the vegetables. Cook for 1–3 minutes to remove the raw tomato taste and deepen the color. Add 1 tablespoons Cajun seasoning — homemade or store-bought (adjust for heat), ⅓ teaspoons salt — taste before adding, Cajun blends vary in sodium, and ⅓ teaspoons black pepper. Stir and cook for 30 seconds to bloom the spices in the oil. Deglaze with ¼ cup of the reserved pasta water — stir well to lift all the caramelized bits from the bottom of the pan. This is where a significant amount of flavor lives.
Add cream on low heat:
- Reduce heat to LOW — this is critical. Cream added to a hot pan will split and become greasy. Pour 0.5 cups heavy cream — full fat only, low-fat will split slowly into the pan, stirring continuously as you pour. Keep on low heat until fully incorporated and the sauce looks smooth and uniform. Raise heat to medium and simmer gently for 2–3 minutes until the sauce begins to thicken. If too thick, add the remaining pasta water one tablespoon at a time.
Combine pasta and finish:
- Add the drained spaghetti to the pan. Toss gently using tongs until every strand is coated in the Cajun cream sauce. Add 0.3 cups Parmesan cheese, freshly grated — Halal-certified Parmigiano Reggiano and toss again — the cheese melts from the residual heat. Taste and adjust: more Cajun seasoning for heat, more Parmesan for richness, a squeeze of lemon to brighten if the sauce feels heavy.
Plate and serve immediately:
- Plate immediately — Cajun cream sauce thickens as it cools. Garnish with 2 tablespoons fresh parsley or cilantro, for garnish and a pinch of extra Cajun seasoning or red chili flakes if desired. Serve alongside garlic bread or a simple green salad. For a complete Cajun spread, serve with Cajun Garlic Butter Sauce on the side.
Notes
Halal note: All ingredients in this recipe are halal-friendly. Use Halal-certified Parmesan (Parmigiano Reggiano Halal is available in UAE supermarkets and most international stores). For protein, use halal chicken, shrimp, or lamb/chicken sausage.
PROTEIN ADD-ON GUIDE — add at Step 3 after aromatics:
Cajun Chicken: Season 200g boneless chicken thigh strips with ½ teaspoon Cajun seasoning. Push aromatics to the sides. Sear on high heat 3–4 min per side without stirring — undisturbed contact creates the Cajun crust. Add back in before tomato paste.
Cajun Shrimp: Season 200g peeled shrimp with ½ teaspoon Cajun seasoning. Cook 1–2 min per side on high heat until pink. Remove from pan and add back only in the final toss — shrimp overcooks in under a minute.
Halal sausage (lamb or chicken): Slice into rounds. Cook in a dry pan over medium-high heat 3–4 min per side until browned. Add to sauce before cream.
Why the pasta water matters. The dissolved starch in pasta water helps the cream sauce cling to every strand of spaghetti rather than pooling at the bottom of the bowl. Always reserve it before draining — this is the technique restaurant kitchens use.
Cajun vs Creole. Cajun seasoning is spicier — more cayenne. Creole seasoning is milder and herb-forward. Substitute Creole for a family-friendly, lower-heat version in equal quantity.
Cream will split on high heat. Always reduce to LOW before adding cream. Pour slowly while stirring. Raise heat only after fully incorporated.
Taste before salting. Commercial Cajun blends vary widely in sodium — some contain up to 400mg per teaspoon. Add salt conservatively after seasoning and adjust at the end.
One-pot version: Instead of boiling pasta separately, add 200g dry spaghetti directly to the sauce after Step 4. Pour in 400ml water or stock. Cover and cook on medium heat for 10–12 minutes, stirring frequently, until pasta is cooked and liquid absorbed.
Storage: Airtight container, refrigerator, 3–4 days. Reheat stovetop with a splash of milk or cream on low heat, covered — steam method keeps the sauce creamy. Microwave on 60% power with a damp paper towel cover. Do not freeze with cream sauce — cream separates when thawed.
