How to Make 5-Ingredient Beef & Onion Foil Packet Dinner

Step 1: Preheat and Prep

Preheat your oven to 400°F (200°C). Tear off large sheets of foil and lightly oil the center.

Place beef in the center of the foil. Top generously with sliced onions. Drizzle with olive oil or dot with butter, then season well with salt and pepper.

Step 3: Seal the Foil

Fold the foil over the beef and onions, sealing tightly to create a packet that traps steam and flavor.

Step 4: Cook Until Tender

Place packets on a baking sheet and bake for 30–40 minutes, depending on thickness and cut of beef. The onions should be soft and the beef tender.

Step 5: Serve Hot and Cozy

Carefully open the foil (watch the steam!) and serve straight from the packet or over your favorite side.
