Gather all your ingredients. Shell and devein the shrimp if not already done. Mince the garlic and chop the red chili peppers. Rinse and chop the fresh parsley.
In a large skillet, heat the olive oil and butter over medium heat. Allow the butter to melt completely and start bubbling.
Add the minced garlic and chopped red chili peppers to the skillet. Sauté for about 1-2 minutes, or until the garlic becomes fragrant and slightly golden. Be careful not to burn the garlic as it can turn bitter.
Add the shrimp to the skillet in a single layer. Season with sea salt and pepper. Cook for about 2-3 minutes on one side, then flip the shrimp to cook the other side. The shrimp should turn pink and opaque when fully cooked.
Once the shrimp is cooked through, remove the skillet from heat and stir in the chopped parsley. This will add a fresh flavor and vibrant color to the dish.
Transfer the Chili Garlic Shrimp to a serving platter. You can garnish with additional parsley or chili if desired. Serve immediately with rice, noodles, or a fresh salad.
