Steak Potato Mushroom Kabobs

Steak Potato Mushroom Kabobs are one of those easy grilled dinners that feel a little extra special without requiring much effort. Tender steak, buttery potatoes, and savory mushrooms cook together on skewers for a meal that feels hearty, rustic, and incredibly satisfying. Meanwhile, the garlic herb marinade brings rich steakhouse flavor while helping every bite stay juicy and delicious.

Because the potatoes are briefly cooked first, everything finishes grilling at just the right time. As a result, you get beautifully charred steak, tender mushrooms, and potatoes with lightly crisped edges. It is the kind of dinner that feels equally perfect for a casual weeknight or a backyard cookout with friends.

Kabobs have been enjoyed around the world for generations because they cook quickly and create incredible smoky flavor over high heat. Luckily, this version keeps things simple while still tasting restaurant-worthy.

Recipe Yield: 4 servings

INGREDIENTS

1 ½ lbs. sirloin steak, cut into 1½-inch cubes
1 lb. baby Yukon Gold potatoes
12 oz. cremini mushrooms, halved if large
2 Tbsp. olive oil
3 Tbsp. unsalted butter, divided
4 garlic cloves, minced
1 Tbsp. Worcestershire sauce
1 tsp. Dijon mustard
1 tsp. fresh lemon juice
1 tsp. kosher salt
¾ tsp. black pepper
1 tsp. smoked paprika
1 tsp. garlic powder
1 tsp. dried Italian seasoning
½ tsp. onion powder
¼ tsp. crushed red pepper flakes (optional)
1 Tbsp. fresh parsley, chopped

INSTRUCTIONS

1. Prep the potatoes:
Place the baby potatoes in a medium pot and cover with water. Add a generous pinch of salt and bring to a gentle boil. Cook for 12–15 minutes, depending on size, until fork-tender but still firm enough to hold shape on skewers. Drain well and let cool for about 10–15 minutes. If potatoes are larger than 1–1¼ inches, cut them in half for even cooking.

2. Make the garlic herb marinade:
In a large bowl, whisk together 2 Tbsp. melted butter, olive oil, garlic, Worcestershire sauce, Dijon mustard, lemon juice, salt, pepper, smoked paprika, garlic powder, Italian seasoning, onion powder, and crushed red pepper flakes if using.

3. Marinate the steak and vegetables:
Add the steak cubes, cooled potatoes, and mushrooms to the bowl. Gently toss until evenly coated. Let marinate for 20–30 minutes at room temperature for the best flavor. Meanwhile, soak wooden skewers in water for at least 20 minutes if using.

4. Build the kabobs:
Thread the steak, potatoes, and mushrooms onto skewers, alternating ingredients for even cooking and beautiful presentation. Leave a small amount of space between pieces so heat circulates properly and encourages better browning.

5. Preheat the grill:
Preheat the grill to medium-high heat (425°F–450°F) and lightly oil the grates to help prevent sticking.

6. Grill the kabobs:
Place the kabobs on the grill and cook for 10–13 minutes total, turning every 2–3 minutes for even browning and caramelization. Grill until the steak develops lightly charred edges and reaches your preferred doneness: 130°F for medium-rare, 135°F for medium, or 140°F–145°F for medium-well. The potatoes should be lightly crisped on the edges and the mushrooms tender.

7. Finish and serve:
Melt the remaining 1 Tbsp. butter and lightly brush it over the hot kabobs for extra richness and shine. Let rest for 3–5 minutes before serving so the steak stays juicy. Sprinkle with fresh parsley and serve warm.

Helpful Tips to Perfect This Recipe

• Parboil the potatoes first: Potatoes naturally take longer to cook than steak. Therefore, boiling them beforehand guarantees tender centers while allowing the outside to crisp beautifully on the grill. As a result, everything finishes cooking at the same time.
• Choose the right steak cut: Sirloin steak works beautifully because it stays tender, flavorful, and budget-friendly. However, ribeye or New York strip also taste incredible for a more luxurious variation.
• Avoid overcooking the steak: Since sirloin is a leaner cut, it cooks quickly. Consequently, using an instant-read thermometer helps guarantee juicy, tender steak every time instead of dry kabobs.
