If you are looking for something easy and delicious to put together for dinner, try this Steak and Potato Foil Pack Dinner with potatoes, mushrooms, and broccoli!


Units Scale
  • 1lb. Top Sirloin Steak
  • 1 lb. fingerling potatoes, divided
  • 2 Broccoli Crowns, divided
  • 1 large yellow onion, cut into chunks and divided
  • 1 c. sliced mushrooms, divided
  • 4 tbsp. Olive oil
  • 5 tbsp butter, room temperature
  • 1 tsp. Garlic salt
  • 1 tsp. Fresh Rosemary, finely chopped
  • 1 tsp. Dried Thyme


  1. Preheat oven to 400 Degrees.
  2. For each foil packet (this recipe makes 2), take two long pieces of aluminum foil. One part goes up and down; the other goes straight across, creating a “t.” In the middle of each foil packet, add half of the cut yellow onion and half the fingerling potatoes. Keep everything centered as much as possible.
  3. Cut the broccoli florets off of the broccoli crowns. Add the florets of one crown to one of the packets and use the other florets for the other packet. 
  4. Add the sliced mushrooms to the packet and slice the steak into 1-inch pieces and eight strips. Place 4 strips on top of the veggies and place them in the packet.
  5. Season with salt and pepper to taste and drizzle each packet with 2 tbsp Olive oil. Fold the aluminum foil on all sides making a packet and sealing all ingredients. Place the packets on top of a baking sheet and in the oven and allow to roast, undisturbed, for 30 minutes. The steak should be cooked to medium. Cook longer if you prefer.
  6. Once the potatoes are fork-tender, your packet is done. 
  7. Add the soft butter, rosemary, dried thyme, and garlic salt in a small bowl and stir to blend. Once the foil packets are done, place a heaping dollop of the butter inside each packet and reseal to allow the butter to melt and the steak to rest for about 5-10 minutes. Don’t worry, the aluminum foil will keep everything warm.
  8. Place the foil packet on a plate and serve.
