Start by heating a large skillet over medium-high heat and add the olive oil. Once shimmering and fragrant, add the zucchini slices in a single layer. Cook for about 2-3 minutes, until they start to turn golden on the edges and release a nutty aroma. Toss or flip them to cook evenly.
Push the zucchini to the sides of the skillet and add the shrimp in the center. Cook for about 2-3 minutes per side, until they turn pink, opaque, and develop crispy edges. You should hear a gentle sizzle and see the shrimp curl up slightly.
Add the minced garlic over the shrimp and zucchini. Cook for about 30 seconds, stirring gently, until the garlic becomes fragrant and slightly golden, filling your kitchen with a savory aroma.
Sprinkle the red pepper flakes over the ingredients for a touch of heat. Squeeze fresh lemon juice over everything, then toss gently to combine, allowing the flavors to meld for about 1 minute.
Season with salt and freshly ground pepper to taste. Check the seasoning, adjusting as needed, and cook for another minute to ensure everything is heated through and flavorful.
Remove the skillet from heat and transfer the shrimp and zucchini to a serving plate. Garnish with extra lemon wedges or herbs if desired. Serve immediately while hot and fragrant.
