These garlic shrimp and avocado skewers have become my go-to for summer grilling and easy entertaining. Juicy shrimp are quickly marinated in garlicky olive oil then kissed by the grill alongside creamy chunks of avocado and sweet red onion for an appetizer or light supper that always gets rave reviews. Perfect for serving with a squeeze of fresh lemon and enjoyed with friends outside.
These skewers are always a crowd-pleaser at my family barbecues. The first time I tossed avocado on the grill, everyone was curious but quickly hooked by that creamy smoky bite.
Ingredients
- Large raw shrimp: Provides the juicy and meaty backbone for each skewer. Opt for wild caught if possible.
- Olive oil: Is the base of the marinade lending rich flavor. Choose extra virgin for the best taste.
- Fresh garlic: Imparts punchy depth. Use plump cloves and mince right before use.
- Lemon juice: Adds brightness and keeps things fresh. Go for freshly squeezed.
- Smoked paprika: Brings gentle warmth and a hint of earthiness. Try Spanish smoked for added depth.
- Sea salt and black pepper: Enhance all the other flavors. Always use fresh cracked pepper for best results.
- Red pepper flakes: Deliver a subtle kick. Adjust to your spice preference.
- Fresh parsley: Gives color and freshness. Finely chop for even distribution.
- Ripe avocados: Add creamy richness. Select ones that are just firm to the touch but give slightly when pressed.
- Red onion: Offers a touch of sweetness and color. Use a medium bulb for even chunks.
- Lemon wedges: Finish everything with tangy pop. Squeeze at the table for brightness.
Step-by-Step Instructions
- Prepare the Marinade:
- Whisk olive oil, fresh garlic, lemon juice, smoked paprika, sea salt, black pepper, red pepper flakes, and parsley together in a medium bowl until fully combined. This builds the flavor foundation for the shrimp.
- Marinate the Shrimp:
- Add the peeled and deveined shrimp to the bowl. Toss thoroughly so each piece is evenly coated. Let the shrimp marinate for about ten minutes at room temperature, which allows the flavors to soak in.
- Assemble the Skewers:
- Thread shrimp, avocado cubes, and red onion chunks alternately onto your skewers. Start and end with a piece of shrimp for stability. This helps keep the avocado from slipping off.
- Preheat the Grill:
- Heat your outdoor grill or grill pan to medium-high and give the grates a quick brush with oil to prevent sticking. The high heat will help caramelize the shrimp.
- Grill the Skewers:
- Place skewers on the grill and cook for two to three minutes per side, turning once. The shrimp should turn opaque and the avocado should get delicious grill marks. Resist the urge to overcook shrimp so they stay juicy.
- Serve and Garnish:
- Transfer grilled skewers to a platter and add lemon wedges on the side. Squeeze over before eating to brighten all the flavors.

I always look forward to grilling avocados for this recipe. Their creamy texture is such a pleasant surprise, especially when paired with the garlicky shrimp. It always reminds me of fun lakeside cookouts with my family where everyone gathers around the grill.
Storage Tips
Leftover shrimp and avocado skewers keep well if stored in an airtight container in the refrigerator for up to one day. Since avocado can brown over time, try to enjoy these fresh. If prepping ahead, keep shrimp and veggies separate and assemble right before grilling.
Ingredient Substitutions
You can swap lime juice for lemon for a tropical twist. Other herbs like cilantro or basil work well if you are out of parsley. Instead of red onion, try sweet Vidalia or bell pepper for extra color. If you like more heat, add extra red pepper flakes or a touch of hot sauce to your marinade.
Serving Suggestions
These skewers make a bright starter but can double as a main when served atop a fresh green salad or some coconut rice. For heartier appetites, pair with crusty gluten free bread and a crisp white wine. A simple side of grilled corn or a tangy tomato salad completes the meal.
Cultural and Historical Context
Grilling shrimp on skewers is a classic technique found from the Mediterranean to Latin America. Blending shrimp with avocado and bright citrus flavors is inspired by coastal cuisine where fresh seafood and seasonal produce always have a starring role. This dish captures a bit of that sunny vacation feeling that everyone loves.
