My uncle always made these on cool weekend afternoons, and the aroma would fill the whole house. I still can’t believe something with only 4 ingredients could turn out so comforting and delicious.

Directions:

Step 1: Assemble the Packets
Preheat the oven to 400°F. Divide the potatoes, onions, and sausage evenly between 4 large sheets of heavy-duty foil.

Tip: Heavy-duty foil works best because it keeps the steam trapped inside, helping the potatoes cook evenly and stay tender.

Step 2: Add the Butter
Top each packet with pieces of butter, distributing them evenly over the ingredients.

Tip: As the butter melts, it coats the potatoes and sausage with rich flavor while helping everything cook together.

Step 3: Seal the Packets
Fold the foil over the ingredients and crimp the edges tightly to seal. Leave a little space inside each packet for steam to circulate.

Visual Cue: The packets should look like sealed pouches with enough room inside for the ingredients to steam properly.

Step 4: Bake
Place the packets on a baking sheet and bake for 35–45 minutes.

Visual Cue: The potatoes should be fork-tender and the packets slightly puffed from the steam inside.

Step 5: Optional Crisp Finish
For extra browning, carefully open the tops of the packets and bake for another 5–10 minutes.

Tip: Opening the packets at the end allows some moisture to evaporate, giving the sausage and onions a richer roasted flavor.
