Ingredients

Scale

Main Ingredients

  • 1 1/2 pounds thinly sliced beef steak (such as sirloin or round)
  • 2 large yellow onions, thinly sliced
  • 1 1/2 pounds baby potatoes, halved or small potatoes cut into 1-inch chunks
  • 3 tablespoons olive oil
  • 2 teaspoons steak seasoning (or your favorite all-purpose seasoning blend)
  • Salt and black pepper, to taste (optional, depending on your seasoning blend)
  • Nonstick cooking spray (for foil, optional)

Instructions

  1. Preheat Oven: Preheat your oven to 400°F (200°C). Line a large baking sheet with foil to simplify cleanup. Tear off 4 large sheets of heavy-duty aluminum foil, about 12×18 inches each, and lightly spray the center of each sheet with nonstick cooking spray if desired to prevent sticking.
  2. Prepare Vegetables and Beef: Thinly slice the yellow onions and halve the baby potatoes or cut larger potatoes into 1-inch chunks. Pat the beef dry with paper towels and slice into strips if not pre-sliced thinly.
  3. Season Ingredients: In a large bowl, toss the halved potatoes and sliced onions with olive oil, steak seasoning, and a pinch of salt and pepper if needed. This ensures even seasoning across the vegetables.
  4. Assemble Foil Packets: Divide the seasoned potato and onion mixture evenly among the four prepared foil sheets, placing the mixture in the center. Top each pile with an equal portion of the sliced beef and spread out slightly to ensure even cooking.
  5. Seal Packets: Fold the long sides of each foil sheet up over the filling and fold down tightly to seal. Next, roll up the short ends to form a snug packet, leaving some room inside for air circulation so steam can cook the ingredients evenly.
  6. Bake: Place the packets on the baking sheet and bake at 400°F (200°C) for 30 to 35 minutes, or until the potatoes are tender when pierced with a fork and the beef is fully cooked. For thinner beef slices or if you prefer it less done, open the packets during the last 5 minutes of baking to let steam escape and slightly reduce cooking time.
  7. Check Doneness and Rest: Carefully open one packet, watching for hot steam, and check a potato for tenderness. If not fully tender, reseal and bake for an additional 5 to 10 minutes. Once cooked, remove from the oven and let the packets rest for 3 to 5 minutes before serving.
  8. Serve: Serve the foil packets directly on plates so everyone can enjoy opening their own, or slide the contents into shallow bowls. Spoon any flavorful juices over the top for extra taste.

Notes

  • Use thinly sliced beef for the best cooking results and tenderness.
  • Adjust seasoning amounts depending on your preference or dietary needs.
  • Nonstick cooking spray on foil is optional but helps prevent sticking.
  • Foil packets make cleanup easy and keep flavors sealed in during cooking.
  • For a lower fat option, you may substitute olive oil with avocado oil or reduce the amount slightly.
  • Carefully open foil packets away from your face to avoid steam burns.
