Oven-Baked 5-Ingredient Beef & Onion Foil Packet Dinner

Ingredients:

Step-By-Step Directions:

1. Preheat and prep foil: Heat your oven to 400°F. Line a large baking sheet with foil for backup, then tear off 4 large sheets of heavy-duty aluminum foil (about 12×18 inches each). Spritz the center of each sheet lightly with nonstick cooking spray.

2. Slice the ingredients: Thinly slice your onions, halve the baby potatoes, and cut the beef steak into thin strips if it isn’t already sliced.

3. Season the mix: In a large bowl, toss the potatoes and sliced onions with the olive oil, steak seasoning, and a pinch of salt and pepper until everything is evenly coated.

4. Build the packets: Divide the seasoned potato and onion mixture evenly among the center of the 4 foil sheets. Top each pile with an equal portion of the sliced beef, spreading it out slightly for even cooking.

5. Seal them up: Bring the long edges of the foil together over the top and fold down tightly, then roll up the short ends to create a snug, sealed pouch. Leave a little pocket of space inside for steam to circulate.

6. Bake until tender: Place the pouches on your baking sheet and bake for 30 to 35 minutes until the potatoes are completely fork-tender and the beef is cooked through.

7. Rest and serve: Carefully open a packet to check a potato, watching out for the hot steam. Let the packets rest for 3 to 5 minutes out of the oven, then serve them directly on plates or slide the contents into bowls, making sure to pour those rich, oniony pan juices right over the top.
