Q1: Can I make these skewers without a grill, and what equipment alternatives work best?

Yes, you have several alternatives to an outdoor grill. The Equipment list mentions a grill pan, which is an excellent indoor option that will give you similar char marks and flavor when heated to medium-high heat as described in Step 5. You can also use your oven broiler by placing the skewers on a baking sheet lined with foil about 4-6 inches from the heat source, following the same 3-4 minute timing per side from Steps 8-9. Another option is to bake the skewers at 425°F for about 10-12 minutes total, flipping halfway through, though you won't get the same charred exterior.

Q2: How can I tell when the shrimp are perfectly cooked and not overdone?

Step 9 provides the key visual cues: the shrimp should be fully opaque (no longer translucent) and have turned from gray to pink/white throughout. The total cooking time is 6-8 minutes (3-4 minutes per side as stated in Steps 8-9), but the best indicator is when the shrimp form a loose 'C' shape—this means they're perfectly cooked. If they curl into a tight 'O' or spiral shape, they've been overcooked and will be tough and rubbery. Since the recipe calls for large shrimp (1.5 lbs as listed in the ingredients), they should reach an internal temperature of 120°F if you want to use a thermometer for precision.

Q3: What vegetable substitutions work well if I can't find zucchini or want more variety?

The recipe's vegetables (red and yellow bell peppers, zucchini, and red onion) can be substituted with many alternatives that hold up well on the grill. Yellow squash is nearly identical to zucchini and should be cut into the same 1/2-inch thick rounds mentioned in Step 4. Cherry tomatoes, mushrooms (button or cremini), and chunks of eggplant work excellently and don't require different cooking times from the 3-4 minutes per side in Steps 8-9. You could also use asparagus spears (cut into 2-inch pieces) or chunks of fresh pineapple for a sweet contrast. Just ensure all pieces are cut to approximately 1-inch size as instructed in Step 4 for even cooking, and remember that the marinade in Step 2 will complement most vegetables beautifully.

Q4: Is this recipe truly gluten-free, and what should I watch out for to keep it safe for celiac diets?

Yes, this recipe is naturally gluten-free as designed, since it contains only fresh shrimp, vegetables, olive oil, lemon juice, garlic, and herbs as described in the ingredients and Step 2's marinade. However, you must verify a few things: ensure your shrimp are fresh or frozen plain (some pre-seasoned or breaded varieties contain gluten), check that all dried herbs and spices haven't been processed in facilities with cross-contamination, and confirm your olive oil is pure without additives. If you're serving this with sides, avoid wheat-based accompaniments and opt for rice, quinoa, or gluten-free bread. The Equipment list shows you'll need basic tools that don't introduce gluten risk, making this an excellent safe choice for gluten-free and celiac diets when ingredients are properly verified.

Gluten-Free Shrimp and Vegetable Skewers

These colorful shrimp and vegetable skewers bring together the best of Mediterranean-inspired grilling with a naturally gluten-free approach.

What makes these skewers truly special is their simplicity and versatility. The marinade does double duty, infusing the shrimp and vegetables with bright, aromatic flavors while keeping everything moist during grilling.

This recipe is naturally gluten-free, making it an excellent choice for those with celiac disease or gluten sensitivities. It's also packed with lean protein from the shrimp and plenty of vitamins and fiber from the colorful vegetables.
