Follow these straightforward steps to create your Hawaiian Garlic Shrimp:

1. Prepare Shrimp: Rinse the shrimp under cold water and pat dry with paper towels.
2. Heat Pan: In a large skillet, heat the olive oil and 4 tablespoons of butter over medium heat until melted and sizzling.
3. Sauté Garlic: Add the minced garlic to the pan, cooking for about 1-2 minutes until fragrant but not browned.
4. Add Shrimp: Place the shrimp in the skillet, seasoning with salt, black pepper, and red pepper flakes, if using. Cook for 2-3 minutes on one side.
5. Flip Shrimp: Turn the shrimp over and add the remaining butter, cooking for an additional 2-3 minutes until they turn pink and opaque.
6. Add Lemon Juice: Squeeze the juice of one lemon over the shrimp and toss to coat evenly.
7. Finish Cooking: Remove the pan from heat and garnish with freshly chopped parsley.
8. Serve Immediately: Serve the shrimp hot over cooked rice or noodles for a delightful meal.
