- 2 tbsp olive oil
- 2 cloves garlic, minced
- 1 tsp dried rosemary
- 1/2 tsp smoked paprika

- 1
Preheat your grill to medium-high heat (about 400°F).

In a large bowl, combine the cubed sirloin, potatoes, bell pepper, and red onion.

Drizzle with olive oil, then add minced garlic, dried rosemary, smoked paprika, salt, and pepper.

Toss everything together until well coated, ensuring all ingredients are evenly seasoned.

Tear off four large sheets of heavy-duty aluminum foil. Divide the steak and veggie mixture evenly among the foil sheets.

Bring the edges of the foil together over the food and crimp tightly to seal, creating four secure packets.

Place the foil packets directly on the preheated grill grates. Cook for 25-30 minutes, flipping halfway through.

The packets are done when the potatoes are tender and the steak is cooked to your desired doneness. Carefully open the packets (watch out for steam!).

Garnish with fresh chopped parsley and serve directly from the foil packets for easy cleanup.
Why this recipe works best on a clean grill
A clean grill makes this recipe easier because the grates release food evenly, the heat moves predictably, and old grease does not smoke over the fresh ingredients. When carbon buildup sits on the grate, it can leave bitter flavors, create flare-ups, and make delicate foods stick right when they should sear.
Before cooking, preheat the grill fully, scrape the grate with a bristle-free tool, and lightly oil the surface. If your grill has yellow flames, heavy smoke, stubborn hot spots, or a greasy smell before the food goes on, it may need a deeper cleaning before your next cookout.
