Method
Make the garlic butter
- Mix melted butter, garlic, parsley, lemon juice, salt, and pepper until combined, then pour it into a bowl. Visual cue: the mixture should look glossy and evenly speckled with garlic and parsley.
- Reserve half the garlic butter for basting, and set the rest aside for marinating. Visual cue: you should have two portions of similar color and texture.
Marinate
- Add sirloin steak and large shrimp to the remaining garlic butter and toss to coat well. Visual cue: the cubes and shrimp should look slick and lightly coated all over.
- Marinate for 30 minutes. Visual cue: the steak should look slightly darker and the shrimp should look lightly opaque at the edges.
Assemble skewers
- Thread steak, shrimp, and bell peppers and onions alternately onto wooden or metal skewers. Visual cue: leave small spaces so the heat reaches all sides.
Grill
- Grill over medium-high heat for 3-4 minutes per side, turning once and keeping the grill at steady heat. Visual cue: the steak should develop grill marks and the shrimp should turn pink.
- Baste with the reserved garlic butter during grilling while the kabobs cook. Visual cue: the butter should look melted and lightly sizzling on the surface.
Serve
- Serve immediately after grilling. Visual cue: the shrimp should be pink and the steak should look juicy, not dried out.
Notes
Pro tip: keep shrimp and steak on separate segments as you skewer so you can visually judge doneness, and baste during grilling instead of after so it stays glossy. Store leftovers in an airtight container in the fridge up to 3 days; reheat gently. Freezing isn’t recommended because shrimp texture can soften after thawing. For a lighter option, use 1/2 the butter and replace the rest with olive oil while still mixing with garlic, parsley, lemon juice, salt, and pepper.
