For the grilled shrimp
2 pounds raw jumbo shrimp, peeled and deveined
2 tablespoons olive oil
2 tablespoons fresh lemon zest
2 garlic cloves, minced
1/2 teaspoon crushed red pepper flakes
1/2 teaspoon kosher salt
1/2 teaspoon freshly ground black pepper
1 cup cherry tomatoes, for skewering
fresh basil leaves, for serving
lemon wedges, for squeezing
For the pesto couscous
4 cups fresh basil leaves
1/2 cup finely grated parmesan cheese
1/3 cup toasted pine nuts
3 garlic cloves
1/2 cup to 3/4 cup olive oil
1/2 teaspoon kosher salt
1/2 teaspoon freshly ground black pepper
1/4 teaspoon crushed red pepper flakes
2 cups cooked couscous
Directions
Preheat the grill to the highest setting.
Place the shrimp in a large bowl. In a small bowl, combine olive oil, lemon zest, minced garlic, and crushed red pepper flakes.
Pour the marinade over the shrimp and toss until every piece is well coated. Season with salt and black pepper.
Let the shrimp sit for about 10 to 15 minutes while the grill heats. Avoid marinating longer than 30 minutes.
Thread the shrimp onto skewers. Add cherry tomatoes to the ends of the skewers if desired.
Place the skewers directly on the grill. Cook for 2 to 3 minutes on the first side.
Turn the skewers and grill for another 1 to 2 minutes until the shrimp are opaque and pink. Remove from the grill and let them rest briefly.
Cook the couscous according to the package instructions until tender.
To toast the pine nuts, place them in a small skillet over low heat. Stir frequently for about 5 minutes until golden and fragrant.
In a food processor, combine basil, parmesan cheese, pine nuts, and garlic. Pulse until finely chopped.
With the processor running, slowly pour in the olive oil until the pesto reaches a smooth consistency.
Add salt, black pepper, and crushed red pepper flakes. Blend again and taste to adjust seasoning.
Stir about 1/4 cup of the pesto into the cooked couscous. Add more if desired for stronger flavor.
Transfer the couscous to a serving platter. Top with grilled shrimp skewers.
Garnish with fresh basil and serve with lemon wedges for squeezing over the dish.
Use different grains
Instead of couscous, you can use quinoa, rice, or bulgur for a slightly different texture and flavor.
Add vegetables
Grilled zucchini, bell peppers, or asparagus pair beautifully with the shrimp and pesto.
Make it dairy-free
Skip the parmesan in the pesto and add extra pine nuts or a spoonful of nutritional yeast for flavor.
Use store-bought pesto
If you’re short on time, prepared pesto works perfectly and makes the dish even quicker.
Try different herbs
Swap some of the basil with parsley, cilantro, or mint to create a unique herb blend.
Storage/Reheating
Refrigeration
Store leftover shrimp and couscous in an airtight container in the refrigerator for up to 3 days.
Freezing
The pesto can be frozen for up to 3 months in a sealed container. However, the shrimp and couscous are best enjoyed fresh.
Reheating
Warm the couscous gently in a skillet over low heat with a drizzle of olive oil. The shrimp can be reheated briefly in a pan or microwave, but avoid overcooking to keep them tender.
