In a large bowl, combine lemon juice, olive oil, onion powder, garlic powder, crushed red pepper, kosher salt, and black pepper. Add the shrimp and toss to coat evenly.
02 -
Cover the bowl and marinate the shrimp in the refrigerator for 30 minutes to develop flavor.
03 -
While shrimp marinates, soak wooden skewers in water for at least 30 minutes to prevent burning on the grill.

About 15 minutes before cooking, preheat outdoor grill to medium heat and lightly oil the grill grates.

Drain the shrimp from marinade. Thread a shrimp onto each skewer, followed by a slice of zucchini, a piece of red onion, and a bell pepper piece. Continue alternating shrimp and vegetables until all ingredients are used. If excess shrimp remain, skewer and grill them separately.

Place kebobs on the grill. Cook for 5–6 minutes per side until the shrimp are opaque and the vegetables are lightly charred. For skewers with extra shrimp, grill an additional 3–4 minutes.

Let kebobs rest for 3–4 minutes after grilling. Serve warm, garnished with lemon wedges and chopped parsley if desired.
