Grilled Sirloin Steak Kabobs are not only a great meal idea for large groups but they can also be a freezer meal! The magic of this easy dinner idea is in the marinade.

I’m writing this post on an empty stomach and reminiscing on how delicious these Grilled Sirloin Steak Kabobs were. It’s not fair to stare at these juicy chunks of meat, infused with a rich, garlicky marinade. All complimented by vegetables cooked and grilled to perfection.

My Jimmy Johns sandwich is simply sad in comparison.

The magic is in the marinade, my friends.

Give these bad boys a nice soak in order to maximize the flavor. Also, to take them over the top, reserve about 1/2 cup of the marinade before you pour it over the meat and drizzle it over the finished product.

I’m jealous of my previous self that got to eat these for dinner the other night.

I also have an idea on how you could make this a freezer meal! Just toss the sirloin (minus the veggies) in a plastic freezer bag with the marinade and freeze it. When you want to eat it, let it thaw and then just assemble the meat with fresh veggies. (Bell peppers won’t play nice after being frozen so they need to be fresh). Here are 70+ other freezer meal ideas if you’re into that.

  • Method: Grill
  • Cuisine: American


  • 1 large red onion, quartered and separated
  • 1/2 soy sauce (for Gluten-Free, use coconut aminos or Gluten-free Tamari Soy Sauce)
  • 1/3 cup olive oil
  • 1/4 cup Worcestershire sauce
  • 2 tablespoons dark brown sugar (or honey)
  • 1 teaspoon onion powder
  • 4 garlic cloves, minced
  • 1 teaspoon pepper
  • 2 pounds sirloin steak, cut into 1.5 inch pieces (where to find meat you can trust)
  • 2 red bell peppers, stemmed, seeded, and cut into 1 inch pieces


  1. In a microwave safe bowl, drizzle the onions with a little bit of olive oil and microwave them for about 4 minutes. (They need to be cooked a bit before being skewered.)
  2. In a small mixing bowl, combine the soy sauce, olive oil, Worcestershire sauce, brown sugar, onion powder, garlic, and pepper. Stir until combined.
  3. Thread the beef, onion, and bell peppers onto a skewer. In a large baking dish, pour the marinade over the kabobs and let them marinade for at least an hour or up to 24 hours.
  4. Remove kabobs from marinade. Cook them on a pre-heated grill or grill pan over medium heat for about 8-10 minutes, turning to cook evenly.


Since onions and bell peppers wouldn’t freeze well alone, you could make this a freezer meal by freezing the beef in the marinade and then just use fresh vegetables when you want to cook it.
