Ingredients
Method
Make the garlic butter
- In a bowl, mix melted butter with minced garlic, chopped parsley, lemon juice, salt, and pepper until evenly combined. The mixture should look glossy and fragrant.
- Reserve half of the garlic butter for basting, and keep the rest for marinating. Set aside so it’s ready for the grill.
Marinate
- Add cubed sirloin steak and peeled shrimp to the remaining garlic butter, coating all surfaces. Cover and marinate for 30 minutes.
Assemble skewers
- Thread steak, shrimp, and bell peppers and onions alternately onto skewers, leaving small gaps for even grilling. Arrange so both steak and shrimp are visible on the skewers.
Grill and baste
- Preheat the grill to medium-high heat, then place the kabobs on the grate. Grill with the lid closed as much as possible.
- Grill for 3 to 4 minutes per side, basting with the reserved garlic butter during grilling. Look for browned edges on the steak and pink, opaque shrimp.
Serve
- Transfer kabobs to a platter and serve immediately. The garlic butter should still look melted and shiny.
Notes
For best results, keep shrimp separate from long cooking exposure by assembling skewers so the shrimp aren’t tightly packed together. Marinated steak-and-shrimp can be refrigerated up to 1 day; cook within that window for the juiciest texture. Freezing cooked kabobs isn’t recommended due to shrimp texture. Dietary swap: use vegan butter in the garlic-butter steps for a dairy-free option.
