What Kind of Shrimp Should I Use?

For the best Cajun Shrimp with Garlic Butter Sauce, I recommend using large or jumbo shrimp. They stay plump and juicy when cooked, and their size allows them to hold onto all that flavorful Cajun seasoning and buttery garlic sauce. If you’re using frozen shrimp, make sure to thaw them properly before cooking. You can use peeled and deveined shrimp for convenience, but leaving the tails on adds a bit more flavor and a nice presentation.

Options for Substitutions

If you need to make some adjustments based on what you have on hand or dietary preferences, here are a few easy swaps:

Shrimp Alternatives – If you don’t have shrimp, try scallops, chicken, or even tofu for a vegetarian twist.
Butter Substitute – Use olive oil or ghee instead of butter for a dairy-free version.
Mild Cajun Option – Reduce the spice by using less cayenne or opting for a mild Cajun seasoning blend.
Garlic Options – Fresh garlic is best, but garlic powder can work in a pinch (use about ½ teaspoon for every clove).
Lemon Juice Alternative – If you don’t have fresh lemon juice, a splash of white wine or apple cider vinegar can add a similar acidity.

Ingredients for This Cajun Shrimp with Garlic Butter Sauce

Every ingredient in this recipe plays an essential role in creating the perfect balance of spice, richness, and freshness.

Shrimp – Large or jumbo shrimp are best for a juicy, meaty bite that soaks up the flavors.
Butter – The base of the sauce, adding richness and enhancing the Cajun spices.
Garlic – Freshly minced garlic infuses the butter with a deep, savory aroma.
Cajun Seasoning – The star of the dish, providing a bold and slightly smoky heat. Use store-bought or homemade.
Paprika – Enhances color and adds a sweet, smoky depth.
Cayenne Pepper – Gives an extra kick for those who love more heat (optional).
Lemon Juice – Brightens the dish with a touch of acidity, balancing the richness.
Fresh Parsley – Adds a pop of color and freshness to the final dish.
Olive Oil – Helps coat the shrimp evenly with seasoning while preventing burning.
Salt & Pepper – Simple but essential for bringing out all the flavors.

Step 1: Season the Shrimp

Pat the shrimp dry with a paper towel to help the seasoning stick better. In a bowl, toss the shrimp with olive oil, Cajun seasoning, paprika, cayenne pepper (if using), salt, and black pepper. Mix well to ensure each shrimp is evenly coated.

Step 2: Sauté the Shrimp

Heat a large skillet over medium-high heat. Add a bit of olive oil, then place the shrimp in a single layer. Cook for about 1-2 minutes per side, or until they turn pink and opaque. Remove the shrimp from the pan and set aside.

Step 3: Make the Garlic Butter Sauce

In the same skillet, reduce the heat to medium and melt the butter. Add the minced garlic and sauté for about 30 seconds until fragrant. Be careful not to burn it!

Step 4: Combine Everything

Return the cooked shrimp to the pan and toss them in the garlic butter sauce. Squeeze fresh lemon juice over the shrimp and stir in the chopped parsley for a fresh finish.

How Long to Cook the Cajun Shrimp with Garlic Butter Sauce

Shrimp cook incredibly fast, so it’s important to keep an eye on them. They usually take about 1-2 minutes per side over medium-high heat. You’ll know they’re done when they turn pink and opaque. Overcooking can make them rubbery, so remove them from the heat as soon as they’re fully cooked.

Tips for Perfect Cajun Shrimp with Garlic Butter Sauce

Pat the shrimp dry before seasoning to help the spices stick and prevent excess moisture in the pan.
Use high heat to quickly sear the shrimp, locking in flavor and preventing them from becoming mushy.
Don’t overcook the garlic—it should be fragrant but not browned, as burnt garlic can turn bitter.
Adjust the spice level by increasing or decreasing the cayenne and Cajun seasoning.
Squeeze fresh lemon juice at the end to brighten the flavors and balance the richness of the butter.
Serve immediately for the best texture and taste, as shrimp are best enjoyed fresh off the pan.

Watch Out for These Mistakes While Cooking

Even though this recipe is simple, a few common mistakes can affect the final dish:

Overcooking the shrimp – They cook fast! Leaving them on the heat too long can make them tough and rubbery.
Not drying the shrimp before seasoning – Excess moisture prevents the seasoning from sticking and can cause steaming instead of searing.
Using too much heat for the garlic – Garlic burns quickly; keep the heat at medium when making the butter sauce.
Skipping the lemon juice – It adds balance and freshness to the dish, making a big difference in flavor.
Using low-quality Cajun seasoning – Some store-bought blends have too much salt and not enough spice. Opt for a good-quality brand or make your own.

What to Serve With Cajun Shrimp with Garlic Butter Sauce

This dish is incredibly versatile and pairs well with many sides. Here are eight delicious options:

1. Rice

White rice, brown rice, or even Cajun dirty rice makes a perfect base to soak up the garlic butter sauce.

2. Pasta

3. Crusty Bread

A fresh baguette or garlic bread is great for mopping up every drop of that flavorful sauce.

4. Roasted Vegetables

Storage Instructions

If you have leftovers, here’s how to store them properly:

Refrigeration – Store the cooked shrimp in an airtight container in the fridge for up to 3 days.
