Garlic Butter Steak and Potato Foil Packets Recipe
Introduction
Garlic Butter Steak and Potato Foil Packets are a simple and flavorful meal perfect for grilling or baking. This dish combines tender steak, seasoned baby potatoes, and aromatic garlic butter, all cooked together in easy foil packets for minimal cleanup.

Ingredients
- 1 ½ pounds steak (sirloin recommended)
- 1 pound baby potatoes, cut into ½ inch pieces
- 1 onion, peeled, halved and thinly sliced
- 1 tablespoon olive oil
- 2 tablespoons chopped fresh parsley
- 1 tablespoon minced garlic (or more to taste)
- 1 tablespoon Italian seasoning
- Salt and pepper, to taste
- 2 tablespoons butter, cubed
Instructions
- Step 1: Par-boil the potatoes by placing them in boiling, salted water. Cook for 5 minutes, then drain and transfer to a large bowl. Let them cool for about 10 minutes until easy to handle.
- Step 2: Cut the steak into pieces based on your preferred doneness: 2.5-3 inches for well-done, 3-4 inches for medium, or 5 inches for rare. Marinate the steak if desired.
- Step 3: In a large bowl, combine the steak, potatoes, sliced onion, olive oil, parsley, garlic, Italian seasoning, salt, and pepper. Toss everything well to coat evenly.
- Step 4: Prepare four sheets of aluminum foil, each at least 12×12 inches. Divide the steak and potato mixture evenly among the foil sheets, placing it in the center.
- Step 5: Top each pile with cubed butter. Fold the foil over the ingredients and seal the packets tightly.
- Step 6: For grilling, place the foil packets on a hot grill and cook for 8-10 minutes per side, or until the potatoes are tender. Adjust timing based on steak thickness and temperature.
- Step 7: For oven cooking, bake the packets at 425°F for about 20 minutes or until the steak reaches your preferred doneness. To add a char, open the packets and broil for 1-2 minutes at the end.
- Step 8: Carefully open the packets as hot steam and juices will escape. Serve immediately.
Tips & Variations
- Par-boiling the potatoes ensures they cook fully and stay tender inside the foil packets.
- Feel free to add your favorite vegetables like bell peppers or mushrooms for extra flavor and nutrition.
- Use fresh herbs like thyme or rosemary instead of Italian seasoning for a different aroma.
- For a richer taste, increase the amount of garlic or butter.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through. Avoid reheating in foil packets as it can cause uneven heating and sogginess.

Ingredients
Steak and Potatoes
- 1 ½ pounds steak (sirloin preferred)
- 1 pound baby potatoes, cut into ½ inch pieces
- 1 onion, peeled, halved, and thinly sliced
Seasonings and Others
- 1 tablespoon olive oil
- 2 tablespoons chopped fresh parsley
- 1 tablespoon minced garlic (or more to taste)
- 1 tablespoon Italian seasoning
- Salt and pepper, to taste
- 2 tablespoons butter, cubed
Instructions
- Par-boil the potatoes: Place the sliced baby potatoes into a pot of boiling salted water and cook for 5 minutes. Drain them immediately and transfer to a large bowl. Let cool for about 10 minutes until safe to handle.
- Prep the steak: Cut the steak into desired piece sizes based on preferred doneness—2.5 to 3 inches for well done, 3 to 4 inches for medium, and about 5 inches for rare. Optionally, marinate the steak as preferred.
- Combine ingredients: In a large bowl, toss the cut steak, par-boiled potatoes, sliced onion, olive oil, fresh parsley, minced garlic, Italian seasoning, salt, and pepper together thoroughly.
- Assemble foil packets: Lay out four sheets of aluminum foil, each at least 12×12 inches. Evenly distribute the steak and potato mixture among the foil centers. Top each packet with cubed butter, then fold and tightly seal the foil around the contents.
- Cook the foil packets on the grill or fire: Place the foil packets on a hot grill and cook for 8-10 minutes per side or until the potatoes are tender. Adjust cooking times if using different foil or steak sizes, and consider using an oven thermometer to check doneness. If cooking over a fire without a grilling rack, place packets on a 2-inch bed of hot coals.
- Cook the foil packets in the oven: Preheat the oven to 425°F (220°C). Bake the foil packets for approximately 20 minutes, checking doneness from 15 minutes onward. For a charred finish, carefully open the packets and broil for 1-2 minutes before serving.
- Serving caution: When opening foil packets, be careful of escaping hot steam and juices to avoid burns.
Notes
- Par-boiling the potatoes ensures they cook thoroughly and evenly inside the foil packets.
- Adjust steak piece sizes depending on your preferred level of doneness.
- Using fresh herbs like parsley enhances the freshness and flavor balance.
- Grilling over hot coals adds a smoky flavor but carefully monitor cooking times to avoid overcooking.
- For an extra charred crust, open foil packets near the end of baking and broil briefly.
- Always handle foil packets with caution once cooked due to hot steam inside.
