Ingredients You’ll Need
· 2 (8 oz) steaks (sirloin, ribeye, or round steak)
· 1 1/2 lbs baby Yukon Gold potatoes, thinly sliced
· 1 large yellow onion, thinly sliced
· 4 tablespoons unsalted butter, cut into slices
· 2 cloves garlic, minced
· 1 teaspoon dried thyme or rosemary
· 1 teaspoon garlic powder
· 1 teaspoon salt
· 1/2 teaspoon black pepper
· 1 tablespoon olive oil
· Fresh parsley, chopped (for garnish)
Optional add-ins: 1 cup sliced mushrooms, 1 cup baby carrots, 1 cup green beans, 1/4 teaspoon red pepper flakes for heat, 1 tablespoon Worcestershire sauce, 1/2 teaspoon smoked paprika, 1/4 cup grated Parmesan cheese
Note: For a dairy-free version, use olive oil instead of butter. For a gluten-free version, ensure all seasonings are gluten-free. New York strip, sirloin, ribeye, or filet mignon all work well. Adjust cooking time based on steak thickness and desired doneness. For medium-rare, aim for 130-135°F internal temperature.
Step-by-Step Instructions
- Preheat Oven or Grill: Preheat your oven to 400°F (200°C) or preheat your grill to medium-high heat. If camping, prepare a campfire with hot coals.
- Prepare the Foil: Tear off four large squares of heavy-duty aluminum foil (about 12×12 inches each). Lightly grease the center of each foil square with olive oil or cooking spray to prevent sticking.
- Layer the Potatoes: Divide the thinly sliced potatoes evenly among the foil squares, placing them in the center. Drizzle with a little olive oil and season with salt, pepper, and garlic powder. Toss gently to coat.
- Season the Steaks: Pat the steaks dry with paper towels. Season both sides generously with salt, black pepper, and garlic powder. Place one steak on top of the potatoes in each foil packet.
- Add Onions, Garlic, and Butter: Divide the sliced onions and minced garlic evenly over the top of each steak. Place 1 tablespoon of butter slices on top of each steak. Sprinkle with dried thyme or rosemary.
- Seal the Packets: Bring the sides of the foil together and fold tightly to seal the packets, leaving a little room for steam to circulate inside. Make sure the seal is tight so no juices escape.
- Bake or Grill: Place the packets on a baking sheet and bake for 25-30 minutes, or place directly on the grill and cook for 15-20 minutes, depending on the thickness of your steak and desired doneness.
- Check for Doneness: Carefully open the foil packets (watch out for hot steam!) and check that the potatoes are fork-tender and the steak is cooked to your liking. Use a meat thermometer for accuracy—130-135°F for medium-rare, 140-145°F for medium.
- Garnish and Serve: Garnish with fresh chopped parsley and serve hot directly in the foil packets. Enjoy every juicy, buttery bite.
Tips for the Best Garlic Butter Steak & Potato Foil Packets
· Slice Potatoes Thinly: Thinly sliced potatoes cook faster and more evenly. Use a mandoline for uniform 1/8-inch slices.
· Use Heavy-Duty Foil: Heavy-duty aluminum foil prevents tearing and holds up well to high heat.
· Seal Tightly: A tight seal traps steam and juices, creating a tender, flavorful result. Double-wrap if needed.
· Don’t Overcook the Steak: Steak continues to cook slightly after removing from heat. Pull it out at 130-135°F for medium-rare and let it rest for 5 minutes.
· Pat Steaks Dry: Dry steaks season and sear better. Pat them dry with paper towels before seasoning.
· Add Butter Last: Placing butter on top of the steak ensures it melts down over everything, creating a rich, garlicky sauce.
· Check Potatoes: If potatoes aren’t fork-tender after the initial cooking time, reseal and cook for another 5-10 minutes.
Variations & Substitutions
· Chicken Foil Packets: Substitute chicken breasts for steak. Cook for 25-30 minutes until internal temperature reaches 165°F.
· Shrimp Foil Packets: Use large shrimp instead of steak. Cook for 12-15 minutes until shrimp are pink and opaque.
· Salmon Foil Packets: Replace steak with salmon fillets. Cook for 15-20 minutes until salmon flakes easily.
· Ranch Steak Packets: Sprinkle 1 tablespoon ranch seasoning over the potatoes and steak.
· Spicy Cajun Steak Packets: Add 1 teaspoon Cajun seasoning and 1/4 teaspoon cayenne pepper.
· Vegetable Medley: Add sliced bell peppers, zucchini, or corn to the packets for extra veggies.
Make-Ahead and Freezer Instructions
· Make-Ahead: Assemble the foil packets completely and refrigerate for up to 24 hours. When ready to cook, let them sit at room temperature for 15 minutes, then bake or grill as directed.
· Freezer Method: Assemble the packets, wrap tightly in plastic wrap, then foil, and freeze for up to 3 months. Thaw overnight in the refrigerator before cooking. You can also cook from frozen, adding 10-15 minutes to the cooking time.
Frequently Asked Questions
What is the best cut of steak for foil packets?
Sirloin, ribeye, New York strip, or filet mignon all work well. Sirloin is budget friendly and flavorful, while ribeye is more marbled and tender. Avoid tough cuts like chuck roast.
Can I use frozen steak?
For food safety and best results, thaw steak before cooking. Frozen steak will steam rather than sear, resulting in a less flavorful texture.
How do I know when the steak is done?
Use a meat thermometer for accuracy. 130-135°F for medium-rare, 140-145°F for medium, 150-155°F for medium-well. The steak will continue cooking slightly after removing from heat.
Can I cook these foil packets on a campfire?
Yes! Place the packets directly on hot coals or on a grill grate over the fire. Cook for 15-20 minutes, turning once halfway through. Check for doneness before serving.
How do I store leftovers?
Store in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave. The steak may be slightly less tender when reheated.
Can I use chicken instead of steak?
Yes! Chicken breasts or thighs work beautifully. Cook until internal temperature reaches 165°F, about 25-30 minutes.
What vegetables work best in foil packets?
Potatoes, onions, bell peppers, carrots, green beans, zucchini, mushrooms, and corn all work well. Cut vegetables into uniform pieces for even cooking.
Why are my potatoes still hard?
Potatoes need to be sliced thinly (1/8-inch) to cook through in the same time as the steak. If they’re still hard after cooking, reseal the packets and cook for an additional 5-10 minutes.
