Swap the sirloin for chicken: Use boneless, skinless chicken thighs or breasts cut into chunks. Cook until the chicken reaches 165°F (74°C) internally, adding 5–10 minutes if needed.
Garlic butter version: Replace half the olive oil with melted butter and add an extra clove of garlic for rich, buttery flavor. Top with a small pat of butter before sealing the packets.
Veggie-loaded packets: Add bell peppers, onions, or green beans cut into bite-size pieces. Keep total volume similar so cook time stays about the same.
Cooking Notes
Cut potatoes into smaller, evenly sized pieces (about 3/4 inch) so they cook through at the same rate as the steak.
If using a grill with hot spots, rotate the packets halfway through cooking to prevent scorching on the bottom.
For medium steak, aim for a quick check around the 20-minute mark on the grill and 25 minutes in the oven, then adjust as needed.
Serving Suggestions
Serve the packets with a simple green salad or steamed vegetables for a complete meal.
Drizzle with a little extra olive oil or garlic butter and finish with a squeeze of lemon for brightness.
Pair with crusty bread or dinner rolls to soak up the garlicky juices from the packets.
Tips
Use heavy-duty foil or double-layer regular foil to prevent tearing and leaking.
Don’t overfill each packet; four moderate portions cook more evenly than a couple of very full packets.
Let the packets rest for 3–5 minutes after cooking so the juices redistribute before you open and serve.

Frequently Asked Questions
Can I make these foil packets ahead of time?
-answer Yes. You can assemble the packets up to 8 hours in advance and refrigerate them. Let them sit at room temperature for about 15 minutes before cooking, and add a few extra minutes to the cook time if going straight from cold.
Can I use a different cut of steak?
-answer Yes. Ribeye, strip steak, or top round can work. Choose a tender cut and avoid very tough cuts unless you cut them small and don’t cook past medium to keep them from getting chewy.
How do I keep the steak from overcooking?
-answer Cut the steak into evenly sized chunks, don’t cook much beyond the recommended time, and let the packets rest a few minutes. For pinker centers, start checking for doneness a few minutes early.
Can I cook these in an air fryer?
-answer Yes, if your air fryer is large enough. Place packets in a single layer and cook at 390°F (200°C) for about 18–22 minutes, checking potatoes for tenderness and adjusting time as needed.
