Pat the shrimp dry. Use paper towels to remove excess moisture so they sear, not steam.
Season lightly with salt and pepper.
Preheat your skillet. Heat a large nonstick or stainless skillet over medium-high. Add the olive oil and let it shimmer.
Sear the shrimp. Arrange shrimp in a single layer. Cook 1–2 minutes until the underside turns pink and slightly golden.
Flip and add flavor. Turn the shrimp, then add the minced garlic and red pepper flakes.
Stir gently for 30 seconds so the garlic becomes fragrant but doesn’t brown.
Deglaze and brighten. Add the lemon juice and broth. Toss to coat and let the sauce bubble for 30–60 seconds. Add lemon zest.
Finish and garnish. Turn off the heat as soon as the shrimp are opaque and curled into loose “C” shapes.
Stir in parsley. Taste and adjust salt and pepper.
Serve right away. Plate with extra lemon wedges. Great over steamed vegetables, zucchini noodles, or a scoop of cauliflower rice.
