Pat the shrimp dry with paper towels. Season shrimp lightly with salt, pepper, paprika, and red pepper flakes (if using).
In a skillet or frying pan, heat olive oil and butter over medium heat.
Add garlic and sauté for about 30 seconds until fragrant, being careful not to burn.
Add seasoned shrimp to the skillet and cook for about 2-3 minutes per side until opaque and lightly pink.
Squeeze fresh lemon juice over the shrimp and toss to combine flavors.
Remove from heat, garnish with freshly chopped parsley, and serve immediately.
