Cook pasta according to package instructions, then drain, reserving 1/2 cup pasta water
Cook shrimp in a large skillet with olive oil and 2 tbsp butter over medium-high heat. Season with salt and pepper, cook 2-3 minutes per side, then remove shrimp from the pan
In the same skillet, melt the remaining butter, sauté garlic and red pepper flakes for 1-2 minutes. Add wine (or broth), simmer for an additional 2 to 3 minutes
Add shrimp back to the skillet, toss with cooked pasta, lemon juice, and parsley. Add reserved pasta water if needed for sauce. Season to taste. Serve with lemon wedges and extra parsley. Enjoy!
