Charred edges, juicy steak, and shrimp that stay tender instead of turning rubbery make these grilled garlic butter steak and shrimp kabobs worth firing up the grill for. The garlic butter does double duty here: it seasons the meat before it hits the heat, then turns into a glossy baste that keeps everything tasting rich and fresh right through the last bite. When the skewers come off the grill with browned corners, pink shrimp, and just enough smoke, they feel like a cookout main dish with a little extra polish.
The trick is splitting the garlic butter before anything goes on the skewers. Half gets reserved for basting, and the other half lightly coats the steak and shrimp during the short marinade, which keeps the surface seasoned without drowning the shrimp in fat for too long. Sirloin works well because it stays tender on a fast grill, and the vegetables add enough sweetness to balance the butter and lemon.
Below you’ll find the timing that keeps the shrimp from overcooking, the best way to thread the skewers so everything finishes together, and a few smart swaps if you’re working with what you already have in the fridge.
The steak stayed juicy, the shrimp picked up the garlic butter without getting mushy, and the grill marks were perfect in just a few minutes. I used metal skewers and everything came off clean.
Save these grilled garlic butter steak and shrimp kabobs for the next time you want a fast surf-and-turf dinner with charred edges and glossy garlic butter.
The Part That Keeps the Shrimp Tender Instead of Tight
Shrimp can go from juicy to curled and dry in a narrow window, and kabobs make that even easier to mess up because the steak usually needs a little more time. The fix is to keep the shrimp in the same marinade as the steak, but only for 30 minutes and no longer. That short soak seasons the shrimp without starting to cure it in the lemon juice and salt.
Threading also matters. Cut the steak into even cubes so it cooks at the same pace, and use shrimp that are large enough to hold up to the grill. If your vegetables are chunky, keep them close to the size of the meat pieces so the skewers finish together instead of leaving you with raw onions and overdone shrimp.
- Sirloin steak — Sirloin gives you a good balance of tenderness and flavor without the price tag of a ribeye. Cut it into even pieces so you don’t end up with some cubes still red while others are already past medium.
- Large shrimp — Bigger shrimp hold up better on the grill and are easier to skewer without tearing. Smaller shrimp cook too fast here and are much more likely to dry out before the steak is ready.
- Butter — Melted butter carries the garlic and herbs and gives the finished kabobs their sheen. Olive oil will work in a pinch, but it won’t give you the same rich finish or the same baste on the grill.
- Lemon juice — The lemon brightens the butter and keeps the dish from tasting heavy. Fresh juice matters here because bottled lemon tends to taste dull next to garlic and char.
- Wooden or metal skewers — Metal skewers go straight onto the grill, while wooden skewers need soaking so they don’t scorch. If you use wood, soak them long enough that they feel heavy with water before threading anything on.
Building the Kabobs So Everything Finishes at the Same Time
Mixing the Garlic Butter
Stir the melted butter with the garlic, parsley, lemon juice, salt, and pepper until it looks evenly blended and fragrant. Reserve half before anything touches the meat; if you forget that step, you end up with nothing clean left for basting and the kabobs taste flatter. The butter should be warm and fluid, not hot enough to start cooking the shrimp on contact.
Marinating Without Overdoing the Lemon
Toss the steak and shrimp in the remaining butter and let them sit for 30 minutes. That is enough time for the garlic and herbs to cling to the surface without letting the acid start changing the texture of the shrimp. If the shrimp go in much longer, they can turn a little firm before they ever hit the grill.
Threading for Even Cooking
Alternate steak, shrimp, and vegetables on the skewers so the heat can move around the pieces instead of getting trapped in one dense section. Leave a little space between pieces if you can; tight packing steams the kabobs and blunts the char. If you are using wooden skewers, handle them gently after soaking so they don’t split when you slide the ingredients on.
Grilling and Basting at the End
Grill over medium-high heat for 3 to 4 minutes per side, turning once and brushing with the reserved garlic butter as the kabobs cook. You’re looking for browned edges on the steak and shrimp that have turned opaque with just a little spring left when pressed. If the grill runs hot, pull the kabobs a touch early, because carryover heat will finish the shrimp fast and overcooked shrimp are the one thing that will drag this dish down.
How to Adapt These Kabobs for Different Nights
Dairy-Free Version
Swap the butter for a good olive oil or a plant-based buttery spread. You’ll lose a little of the rich finish, but the garlic, lemon, and parsley still carry the dish, and the kabobs will still brown nicely on the grill.
No-Shrimp Steak Kabobs
If you want to skip the seafood, double the steak and add more peppers and onions. The timing gets a little easier because everything on the skewer can tolerate the same amount of heat, and you can cook the beef to your preferred doneness without worrying about shrimp drying out.
Gluten-Free and Naturally Low-Carb
These kabobs are already gluten-free and low-carb as written, so there is nothing to change for that style of eating. Serve them with grilled zucchini, cauliflower rice, or a simple salad if you want the plate to stay light.
Storage and Reheating
- Refrigerator: Store leftovers in an airtight container for up to 3 days. The shrimp will firm up a little, but the flavor holds well.
- Freezer: Freezing isn’t ideal because cooked shrimp can turn rubbery after thawing. If you need to get ahead, freeze the raw cubed steak and vegetables separately, then add fresh shrimp on grill day.
- Reheating: Reheat gently in a skillet over low heat or in a 300°F oven just until warmed through. High heat will dry out the shrimp fast, so stop as soon as the kabobs lose their chill.

- Thread steak, shrimp, and bell peppers and onions alternately onto skewers. Leave a little space between pieces so they grill evenly.
- Preheat the grill to medium-high heat, then grill the kabobs for 3-4 minutes per side. Baste with the reserved garlic butter as they grill so the surface shines and flavors build.
- Grill until the steak is cooked to your liking and the shrimp turn pink and opaque. Serve immediately for the best texture.
