Season the Shrimp: Pat shrimp dry with a paper towel and season with salt and pepper.
Heat the Pan: In a large skillet, heat olive oil over medium-high heat.
Cook the Shrimp: Add shrimp to the skillet and cook for 2–3 minutes per side until pink and opaque. Remove shrimp from the skillet and set aside.
Make the Garlic Butter Sauce:
Sauté the Garlic: In the same skillet, melt butter over medium heat. Add the minced garlic and red pepper flakes (if using). Sauté for 1–2 minutes until the garlic becomes fragrant, but not browned.
Add the Lemon: Stir in lemon juice and lemon zest to the garlic butter sauce, mixing well.
Combine the Shrimp and Sauce: Return the cooked shrimp to the skillet and toss them in the garlic butter sauce until well coated.
Garnish and Serve:
Finish with Parsley: Sprinkle chopped parsley over the shrimp for a fresh, vibrant touch.
Serve Immediately: Serve the Hawaiian Garlic Shrimp with rice, veggies, or any sides of your choice.
