There’s something so comforting about peeling open a foil packet and being hit with a wave of buttery garlic aroma. These Garlic Steak and Potato Foil Packets are one of my favorite summer dinners because they’re simple, flavorful, and versatile.

Whether you toss them on the grill at a backyard cookout, over a campfire on a family trip, or bake them right in your oven, they come out perfectly tender every time. My kids love opening their own packets at the table—it’s like unwrapping a gift for dinner!

Tips & Tricks
- For tender steak: Don’t overcook—check at 20 minutes.

- Make ahead: Prep packets in the morning and refrigerate until dinner.
- Camping hack: Double wrap in heavy-duty foil so they hold up well over the fire.
FAQ
1. Can I use a different cut of steak?
Yes! Sirloin works best, but ribeye or even stew meat can be used (just adjust cooking time).
2. Can I make these low-carb?
Absolutely—swap the potatoes for cauliflower florets or zucchini.
3. How do I know when the steak is done?
Medium steak will be around 145°F inside. If you like it more well-done, give it a few extra minutes.
