Pro Tips Before You Start
Pat the shrimp dry before marinating so the flavors cling better to the surface.
If using wooden skewers, soak them in water before grilling to help prevent burning.
Do not over-marinate the shrimp, since too much lemon juice can start to change the texture.
Keep the butter sauce warm over very low heat so it stays silky without overcooking the herbs.
How to Make Gluten-Free Grilled Shrimp Scampi
Step 1 – Make the marinade
Pat the shrimp dry and check that they are properly deveined. In a bowl, whisk together olive oil, lemon juice, minced garlic, diced shallots, parsley, sea salt, and black pepper.
Step 2 – Marinate the shrimp
Add the shrimp to the marinade and toss gently to coat. Cover and refrigerate for at least 1 hour.
Step 3 – Prepare the garlic butter sauce
Melt the butter with olive oil in a small saucepan over low heat. Add the garlic and cook for 30 seconds, then remove from heat and whisk in salt, lemon juice, and lemon zest.
Step 4 – Finish the sauce
Stir in the red pepper flakes. Fold in the scallions and parsley just before serving to keep them fresh and bright.
Step 5 – Grill the shrimp
Heat the grill to medium-high and lightly oil the grates. Remove the shrimp from the marinade, discard the liquid, pat the shrimp dry again, then thread them onto skewers and grill for 2–3 minutes per side until pink and opaque.
Step 6 – Serve warm
Remove the shrimp from the skewers and place them on a serving platter. Drizzle generously with the warm garlic butter sauce and serve right away.
What to Serve Them With
Serve this shrimp scampi with gluten-free pasta for a more filling dinner.
It also pairs well with steamed rice, roasted potatoes, or a crisp green salad.
For a simple summer plate, add grilled vegetables or corn on the cob.
Variations / Substitutions
Swap parsley with fresh basil for a slightly different herb flavor.
Use green onions if scallions are not available.
Skip the white wine and add a small splash of broth if preferred.
Add a little extra red pepper flakes if you want more heat.
Storage & Leftovers
Store leftover shrimp in an airtight container in the refrigerator for up to 2 days.
Reheat gently in a skillet over low heat with a spoonful of extra butter or water.
This dish is best enjoyed fresh, since shrimp can become rubbery if reheated too long.
