In a large skillet, heat olive oil and 2 tablespoons of butter over medium heat.
Add minced garlic and sauté for 1-2 minutes until fragrant.
Introduce the shrimp to the skillet and season with salt, pepper, and red pepper flakes.
Cook the shrimp for about 2-3 minutes on each side until they turn pink.
Reduce heat and add the remaining butter to the skillet.
