Ingredients:
- 680g top sirloin steak, cut into 1 inch cubes
- 680g Yukon Gold potatoes, halved or quartered into 1-inch pieces
- 2 tbsp avocado oil
- 4 tbsp unsalted butter, cubed
- 2 tbsp balsamic vinegar
- 1 tbsp Worcestershire sauce
- 1 tsp smoked paprika
- 1/2 tsp coarse sea salt
- 1/2 tsp cracked black pepper
- 4 cloves garlic, smashed
- 2 sprigs fresh rosemary, leaves stripped
Instructions:
- Cube the beef. Slice your 680g of sirloin into uniform 1 inch cubes.
- Whisk the marinade. Combine the balsamic vinegar, Worcestershire, smoked paprika, salt, and pepper in a large bowl.
- Toss the steak. Add the beef to the marinade and coat thoroughly.
- Prep the potatoes. Wash and cut the 680g of Yukon Golds into 1 inch pieces.
- Emulsify the mix. Toss potatoes with avocado oil, rosemary, and the smashed garlic cloves.
- Combine and chill. Mix the beef and potatoes together. Store in a leak proof container or gallon sized freezer bag for at least 4 hours, or up to 24 hours.
- Assemble the packets. Divide the mixture into 4 large sheets of heavy duty foil. Top each with 1 tbsp of cubed butter.
- Seal the pouches. Fold the foil edges together tightly to create a leak proof seal. Ensure there is a small pocket of air inside for steam circulation.
- Cook over heat. Place packets on a campfire grate or directly on hot coals. Cook for 20 minutes, flipping halfway through.
- Check and rest. Open one packet carefully. Cook until potatoes are fork tender and beef is browned. Let rest for 5 minutes before eating.
