Make Cajun Garlic Butter Shrimp: A Simple Method

Step 1: Prepare the Marinade
In a small bowl, combine the low sodium soy sauce, light brown sugar, whole grain mustard, and Cajun seasoning. Whisk until the sugar is dissolved and the mixture is well blended.
Step 2: Marinate the Shrimp
Place the peeled and deveined shrimp in a large mixing bowl. Pour the marinade over the shrimp, ensuring they are well coated. Let them marinate for about 15 minutes at room temperature.
Step 3: Sauté the Garlic
In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant, being careful not to let it burn.
Step 4: Cook the Shrimp
Add the marinated shrimp to the skillet in a single layer. Cook for 2-3 minutes on one side until they turn pink, then flip them over and add the unsalted butter. Cook for an additional 2-3 minutes until the shrimp are fully cooked and the butter has melted, creating a rich sauce.
Step 5: Season and Serve
Season the shrimp with salt and pepper to taste. Remove from heat and garnish with sliced green onions before serving. Enjoy your Cajun Garlic Butter Shrimp over rice, pasta, or as a standalone dish.
Low-Carb/Keto Alternatives

- Replace the brown sugar with a low-carb sweetener like erythritol or stevia.
- Serve the shrimp over zucchini noodles or cauliflower rice instead of traditional pasta or rice.
- Use coconut aminos instead of soy sauce for a soy-free option.
- Consider adding more vegetables, like bell peppers or broccoli, to increase the dish’s volume without adding carbs.
Behind the Recipe
This Cajun Garlic Butter Shrimp recipe is inspired by the vibrant flavors of Southern cuisine, particularly the bold and spicy elements characteristic of Cajun cooking. The combination of garlic and butter is a classic in many shrimp dishes, but adding a touch of sweetness and tang from the mustard elevates it to a new level. This is not just a meal; it’s a celebration of flavors that transports you to a warm, sun-soaked bayou.
How to Store & Reheat
Leftover Cajun Garlic Butter Shrimp can be stored in an airtight container in the refrigerator for up to 2 days. To reheat, simply warm the shrimp in a skillet over low heat until heated through. Be cautious not to overcook the shrimp during reheating, as they can become tough.
Your Questions, Answered
Can I use frozen shrimp for this recipe?
Yes, you can use frozen shrimp. Just make sure to thaw them completely and pat them dry before marinating to ensure they absorb the flavors well.
What if I don’t have Cajun seasoning?
If you don’t have Cajun seasoning, you can make your own blend using paprika, cayenne pepper, garlic powder, onion powder, and dried thyme. Adjust the proportions to your taste.
Can I add vegetables to this dish?
Absolutely! Bell peppers, zucchini, or asparagus would be great additions. Just sauté them alongside the garlic before adding the shrimp to ensure they cook through.
Is there a substitute for unsalted butter?
If you need a substitute for unsalted butter, you can use olive oil or a plant-based butter alternative. The flavor may differ slightly, but it will still be delicious!
