This hearty steak kabob recipe has become my go-to summer grilling favorite, combining juicy sirloin steak with colorful garden vegetables for a complete meal on a stick that's sure to impress at any backyard gathering.
I first created these kabobs for a neighborhood cookout five years ago, and they've since become the most requested dish whenever friends come over for summer barbecues. The combination of that savory marinade with the charred vegetables creates a flavor explosion that even my pickiest eaters devour.
Ingredients
- Sirloin steak: Cuts into perfect tender chunks without breaking the bank like more expensive cuts
- Bell peppers: Add vibrant color and sweet crunch that balances the savory meat
- Red onion: Provides a sharp flavor that mellows beautifully when grilled
- Zucchini: Absorbs the smoky grill flavor while adding a nutritious element
- Olive oil: Helps vegetables caramelize perfectly on the grill
For the marinade
- Olive oil: Creates the base that carries all the flavors into the meat
- Soy sauce: Provides that umami depth that makes the steak irresistible
- Fresh garlic cloves: Offer aromatic punch that store-bought powders cannot match
- Worcestershire sauce: Adds complex tanginess and helps tenderize the meat
- Lemon juice: Brings brightness and helps break down tough fibers
- Red wine vinegar: Balances the richness with acidity
- Dijon mustard: Works as an emulsifier while adding subtle spice
- Freshly ground pepper: Provides complexity that pre-ground varieties lack
Step-by-Step Instructions
- Soak the Skewers:
- Place wooden skewers completely submerged in water for at least 30 minutes though overnight is best. This crucial step prevents them from burning on the grill which would ruin your beautiful kabobs and potentially cause flare ups.
- Marinate the Steak:
- Cut sirloin into uniform 1¼ inch chunks ensuring they cook evenly. Place in a zip top bag then combine all marinade ingredients in a bowl whisking until fully integrated. Pour this aromatic mixture over the steak ensuring every piece gets coated. Seal the bag removing excess air and refrigerate for 3 to 6 hours allowing the flavors to penetrate deeply into the meat.
- Prepare the Vegetables:
- Cut bell peppers red onion and zucchini into pieces similar in size to the steak ensuring everything cooks at the same rate. Arrange them on a cutting board drizzle generously with olive oil and season with salt and pepper. Toss everything with your hands making sure each piece is evenly coated for maximum flavor.
- Assemble and Grill:
- Remove steak from marinade and thread alternating pieces of meat and vegetables onto soaked skewers. Preheat your grill to medium high heat between 450 and 500 degrees Fahrenheit. Grill the kabobs for approximately 3 to 4 minutes per side rotating to cook all four sides. This timing yields a perfect medium rare to medium doneness with vegetables that remain slightly crisp.

Make Ahead Options
These kabobs can be prepped up to a day in advance making them perfect for entertaining. Marinate the steak overnight and chop all vegetables storing them separately in airtight containers. You can even assemble the skewers a few hours before grilling just keep them covered and refrigerated. This preparation strategy has saved me countless times when hosting summer gatherings allowing me to enjoy time with guests instead of being stuck in the kitchen.
Customization Ideas
The beauty of kabobs lies in their versatility. Feel free to swap vegetables based on seasonal availability or personal preference. Cherry tomatoes mushrooms or chunks of corn on the cob make excellent additions. For those who prefer chicken simply substitute boneless skinless chicken thighs for the steak using the same marinade but extending the cook time by about 2 minutes per side. Seafood lovers might try firm fish like swordfish or large shrimp reducing the cooking time to just 2 minutes per side.
Serving Suggestions
These kabobs shine when paired with simple sides that complement without competing. A light cucumber and tomato salad dressed with olive oil and lemon juice offers a refreshing contrast to the rich grilled flavors. For a heartier meal serve alongside fluffy basmati rice or warm pita bread with a dollop of tzatziki sauce. When entertaining I often create a build your own kabob bar with prepped ingredients allowing guests to customize their skewers before I grill them to perfection.
