First, heat the butter and olive oil in a large sauté pan over medium heat. Add the garlic and sauté for a minute or two, until it is fragrant and starting to turn golden.

Next, add the shrimp to the pan and cook for about 2 minutes, until they are pink and just starting to curl. Add the white wine, chicken broth, lemon juice, parsley, and red pepper flakes, and stir to combine.

Bring the mixture to a simmer and cook for another 2-3 minutes, until the shrimp are cooked through and the sauce has thickened slightly.

When the shrimp scampi is ready, serve it hot over a bed of pasta, rice, or mashed potatoes. It's also delicious served with a simple green salad or some steamed vegetables.
