Method
Heat olive oil and 2 tablespoons butter in a pan over medium heat.
Add minced garlic and sauté for a couple of minutes until very fragrant.
Add the shrimp and season with salt and freshly ground black pepper.
Cook shrimp about 1 minute on the first side, then flip and cook 1 minute on the other side.
Add chicken broth and crushed red pepper flakes; simmer until liquids reduce by about half.
Stir in lemon juice, the remaining butter, and chopped parsley.
Remove from heat immediately and serve (optionally over rice).
Notes
This fed our family of 5 nicely with no leftovers. Costco sells 2 pound bags of shrimp that we use. We like it with more butter and served over rice.
