How to Make Oven-Baked Steak and Onion Foil Packets
1. Preheat the Oven
Set your oven to 400°F (205°C). Tear off four large sheets of heavy-duty aluminum foil.
2. Season the Steak
In a bowl, toss the steak strips with olive oil, garlic, salt, pepper, paprika, and herbs until evenly coated.
3. Assemble the Packets
Divide the sliced onions among the foil sheets, placing them in the center. Top each onion pile with seasoned steak. If using extra vegetables or Worcestershire sauce, add them now.
4. Seal Tightly
Bring the long sides of the foil together and fold to seal, then fold in the ends to create tight packets. Make sure there’s a little space inside for steam to circulate.
5. Bake
Place the packets on a baking sheet and bake for 25–30 minutes. For more caramelization, carefully open the packets and return them to the oven for 5 minutes.
6. Rest and Serve
Let the packets rest for a few minutes before opening—steam will be hot. Spoon the juices over the steak and onions before serving.
Serving Ideas
Oven-baked steak and onion foil packets pair beautifully with:
Mashed or roasted potatoes
Rice or buttered egg noodles
Crusty bread to soak up the juices
A simple green salad for balance
You can also turn leftovers into steak sandwiches, wraps, or even breakfast hash.
Tips for the Best Results
Slice steak against the grain for maximum tenderness
Don’t overcrowd the packets—space helps everything cook evenly
For extra richness, add a pat of butter before sealing
