How to make Keto Cajun Shrimp: step-by-step guide

Cooking methods

Sautéing

Preparation steps

Gather and measure all the ingredients.
Wash the fresh parsley and chop it finely.
Peel and devein the shrimp if they’re not cleaned.
Cut the lemon into wedges for serving.

Cooking steps

Mix the olive oil, chopped garlic, Cajun spice, cayenne pepper, salt, and black pepper in a big bowl to make the marinade.
Put the cleaned shrimp in the bowl. Make sure all the shrimp are covered with the marinade. Let them sit for about 15-20 minutes so they soak up the flavors.
Turn on your stove and heat up a large pan on medium-high.
When the pan is hot, lay the shrimp in one layer. Cook them for about 2-3 minutes on each side. They’re done when they turn pink.
Take the shrimp out of the pan and put them on a plate. Add some chopped parsley and lemon slices on top, and they’re ready to eat!

Chef’s pro tip

Always ensure your pan is hot before putting in the marinated shrimp. A super-hot pan quickly gives the shrimp a golden crust, sealing in all those tasty juices. Plus, a quick sear helps keep the shrimp tender on the inside.

What to serve with this keto cajun shrimp?

Kale Salad: This keto-friendly kale salad pairs wonderfully with the shrimp, making a flavorful meal.

Include more greens: Serve the shrimp on a mixed greens or spinach bed. This enhances presentation and adds nutrients to the meal.
