• 1/2 tsp paprika
• 1/2 tsp salt
• 1/4 tsp black pepper
• 1 tbsp olive oil
• 1 tbsp fresh parsley, chopped (for garnish)

How to Make Garlic Butter Steak and Potato Foil Packets

Step 1: Prep the Ingredients

1. Preheat the oven to 400°F (200°C).
2. Cut four large sheets of heavy-duty aluminum foil and set them aside.
3. In a large bowl, toss the halved baby potatoes with olive oil, salt, black pepper, paprika, and half the minced garlic until evenly coated.

Step 2: Assemble the Foil Packets

1. Divide the seasoned potatoes evenly among the four foil sheets, placing them in the center of each sheet.
2. In the same bowl, mix the steak bites with the melted butter, dried Italian seasoning, and the remaining minced garlic.
3. Place the steak bites on top of the potatoes in each foil packet.

Step 3: Seal the Foil Packets

1. Fold the foil over the ingredients and seal the edges tightly to trap steam and flavor.
2. Arrange the sealed packets on a baking sheet for easy handling.

Step 4: Bake or Grill

• Oven: Bake for 20–25 minutes, until the potatoes are fork-tender and steak reaches your preferred doneness.
• Grill: Place packets over medium heat for 15–20 minutes, flipping once halfway through.
• Air fryer: Cook at 375°F (190°C) for about 12–15 minutes, shaking or turning once.

Step 5: Serve

1. Carefully open the foil packets — steam will be hot.
2. Garnish with chopped fresh parsley and, if desired, a sprinkle of Parmesan or shredded cheese. Serve immediately.

Pro Tips for the Best Results

• Choose a good-quality steak for the best texture and flavor. Sirloin, ribeye, or filet work well.
• Don’t overcook the steak; carryover heat will continue to cook it after you remove the packets.
• If you worry about undercooked potatoes, microwave the halved potatoes for 3–5 minutes before assembling the packets.
• Prepare packets ahead: assemble and refrigerate for up to 24 hours, then cook when ready.
• For extra flavor, add a pat of butter or a drizzle of olive oil on top of each packet before sealing.

Best Ways to Serve

These foil packets pair well with:

• Grilled vegetables such as asparagus, bell peppers, or zucchini
• Garlic bread or soft dinner rolls
• A fresh green salad to balance the richness
• Cold drinks like lemonade or iced tea for a refreshing contrast

Storage & Reheating

Refrigerate leftovers in an airtight container for up to 3 days. Freeze cooked packets for up to two months. To reheat, warm in a 350°F (175°C) oven for about 15 minutes or heat in an air fryer for best texture; avoid microwaving if you want to keep the steak juicy.
