Grilled Steak Kabobs with Peppers and Mushrooms

Quick Answer

Grilled Steak Kabobs marinate cubed sirloin in a Worcestershire-balsamic marinade, thread it with peppers and mushrooms, and grill with a boiled glaze finish.

Jump to Recipe

Steak kabobs are technically meat and vegetables on sticks, but the stick creates a weird amount of confidence. Suddenly dinner is organized. Cubes of beef, bell peppers, onions, and mushrooms line up like they have been briefed, then hit a hot grill where the edges char and the vegetables soften without disappearing.

The main challenge is size. Cut the steak too small and it overcooks before the peppers are ready; cut the vegetables into giant chunks and the beef is done while the onion is still filing paperwork. Keeping everything close in size helps the skewers cook at roughly the same pace. Mushrooms are especially good here because they absorb seasoning, pick up smoke, and stay meaty enough to belong next to steak.

High heat is what gives kabobs their appeal. You want browned corners, a little blistering on the peppers, and enough space between pieces for hot air to circulate. Crowd the skewer until it looks like airport luggage and everything steams. Give the ingredients breathing room, rotate for even char, and pull the steak when it reaches the doneness you want. It is grilling reduced to small, manageable pieces—which is probably why everybody suddenly thinks they can cook when handed a skewer.

Ingredients

Servings
  • 2 pounds top sirloin, cut into 1½-inch cubes
  • 12 ounces cremini mushrooms, stems trimmed
  • 1 large red bell pepper, cut into 1½-inch pieces
  • 1 large yellow bell pepper, cut into 1½-inch pieces
  • 1 large red onion, cut into 1½-inch pieces
  • 2 tablespoons olive oil
  • 1 teaspoon kosher salt
  • ¼ cup olive oil
  • 3 tablespoons Worcestershire sauce
  • 2 tablespoons soy sauce
  • 2 tablespoons balsamic vinegar
  • 1 tablespoon tomato paste
  • 1 tablespoon brown sugar
  • 4 garlic cloves, minced
  • 1 teaspoon smoked paprika
  • 1 teaspoon onion powder
  • ½ teaspoon black pepper
  • ½ teaspoon kosher salt

Instructions

  1. 1Whisk the olive oil, Worcestershire, soy sauce, balsamic, tomato paste, brown sugar, garlic, smoked paprika, onion powder, pepper, and salt.
  2. 2Reserve ⅓ cup of the marinade in the refrigerator. Add the steak to the remaining marinade and refrigerate for 2 hours.
  3. 3If using wooden skewers, soak them in water for at least 30 minutes. Heat the grill to medium-high.
  4. 4Toss the mushrooms, peppers, and onion with 2 tablespoons olive oil and 1 teaspoon salt.
  5. 5Thread the steak and vegetables onto skewers, leaving a little space between pieces. For the most even cooking, place meat and vegetables on separate skewers; mixed skewers are prettier but may cook less evenly.
  6. 6Grill for 8–12 minutes, turning every 2–3 minutes, until the steak reaches 130–135°F and the vegetables are charred and tender.
  7. 7Boil the reserved marinade in a small saucepan for 3 minutes, then brush it over the kabobs during the final 2 minutes of grilling.
  8. 8Rest the kabobs for 5 minutes before serving.

Pro Tips

  • Skewer meat and vegetables on separate skewers for the most even cooking — they don't need identical time on the grill, and separating them lets you pull each off exactly when it's ready.
  • Always boil the reserved marinade before brushing it onto cooked or cooking meat. It touched raw beef, so a full 3-minute boil is essential.
  • Soak wooden skewers for at least 30 minutes before grilling so they don't scorch and snap over direct heat.

Substitutions

top sirloin → flat iron or ribeye, cubed Both work well cubed; ribeye is richer, flat iron is leaner and just as tender.
cremini mushrooms → white button mushrooms Cremini are deeper in flavor, but button mushrooms work fine.
balsamic vinegar → red wine vinegar plus a pinch of sugar You approximate the tangy-sweet balance without balsamic on hand.

Storage Instructions

Store leftover kabobs (meat and vegetables removed from skewers) in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet or low oven.

Make Ahead

Mix the marinade and cut the vegetables up to a day ahead. Marinate the steak for the full 2 hours right before grilling for the best texture.

Freezing

Freeze the raw steak in its marinade for up to 2 months and thaw overnight before threading and grilling. Cooked kabobs are best fresh.
