If you love Louisiana flavors but are sticking to a keto or low-carb lifestyle, you’re in for a treat. Keto crawfish etouffee is a creamy, flavorful seafood dish that delivers the comforting warmth of Cajun cuisine without the high carb baggage. This keto-pleasant crawfish etouffee uses a light almond-flour roux or an alternative thickener to replicate the conventional texture while keeping net carbs in check. Read on to discover a foolproof recipe, practical tips, and why this dish deserves a permanent spot in your keto meal plan.
What is Crawfish Etouffee?
Crawfish etouffee (frequently enough pronounced “ay-too-FAY”) is a classic Cajun dish from Louisiana. It features succulent crawfish tails simmered in a thick, flavorful sauce, usually thickened with a roux (a mixture of fat and flour) and a soffritto of onions, celery, and bell peppers. The result is a rich, velvety sauce served over rice in traditional Cajun kitchens. For keto cooks, the key is to create a keto-friendly roux or to adjust the sauce with low-carb thickeners while preserving the soul and aroma of Cajun cooking.
Why Keto-Friendly Etouffee Works
The traditional etouffee gets its body from a roux made with flour, which is off-limits on keto. The keto crawfish etouffee adapts by using:
- Almond flour or ground almond for a nutty,low-carb roux
- Butter or ghee as the fat base to build a rich,glossy sauce
- Heavy cream or cream cheese for a creamy,luxurious texture
- Aromatic vegetables in moderation to keep carbs in check
With these adjustments,you still enjoy the iconic Louisiana flavors—garlic,onion,peppers,and tender crawfish—while staying within keto macros. This makes the dish not only keto-friendly but also incredibly satisfying for anyone craving seafood with bold Cajun spice.

These quantities are designed to yield a hearty, restaurant-quality keto crawfish etouffee. You can scale up or down as needed.
- 1 pound crawfish tails, peeled and deveined
- 2 tablespoons unsalted butter
- 1 small yellow onion, finely chopped
- 1 bell pepper (red or green), finely chopped
- 2 celery stalks, finely chopped
- 3 cloves garlic, minced
- 1 cup seafood stock or chicken stock (unsalted)
- 1 cup heavy cream (or coconut cream for dairy-free option)
- 2–3 tablespoons almond flour (for keto roux)
- 1 teaspoon smoked paprika
- 1/2 teaspoon dried thyme

Roux Options for Keto crawfish Etouffee
Roux is optional if you prefer a thickened sauce without flour. Here are two practical keto-friendly options:
Melt butter and whisk in almond flour until lightly browned. This creates a nutty,gluten-free base that thickens as it cooks. Whisk 1/4 teaspoon xanthan gum into 2 tablespoons cold water to create a slurry, than whisk into the simmering sauce until the desired thickness is reached. Simmer the sauce a bit longer to reduce and thicken, then whisk in additional cream if needed.
Step-by-Step Method: How to Make Keto Crawfish Etouffee
- Sauté the aromatics: In a large skillet or sauté pan, melt the butter over medium heat. Add the onion, bell pepper, and celery. Cook until softened and translucent, about 5–7 minutes. Stir in the garlic and cook for another 30–60 seconds.
- Prepare the roux (if using almond flour): Push the vegetables to the side, add an extra tablespoon of butter, then whisk in 2–3 tablespoons almond flour. Cook the roux for 1–2 minutes, stirring constantly, until it turns a light brown color. This helps develop a nutty flavor without burning.
- Add spices: stir in smoked paprika, thyme, cayenne, salt, and pepper.Mix well to coat the vegetables and roux.
- Build the sauce: Pour in the stock and bring to a gentle simmer. If you prefer a creamier sauce, whisk in the heavy cream (or coconut cream) slowly. Simmer for 5–8 minutes until the sauce lightly thickens and coats the back of a spoon.
- Finish with crawfish: Add the crawfish tails to the pan. Simmer for 3–5 minutes until they are heated through. Do not overcook the crawfish, or they may become tough.
- Adjust and finish: Taste and adjust salt,pepper,and heat. A squeeze of lemon juice and a handful of chopped parsley brighten the dish just before serving.
- Serve: Spoon the keto crawfish etouffee over a bed of cauliflower rice or enjoy it on its own for a satisfying low-carb option.
