Toss well. - Cut four large pieces of aluminum foil, each about 12x12 inches. - Place the seasoned steak and potato mixture in the center of each foil piece. - Top each pack with halved cherry tomatoes and drizzle with the rest of the garlic butter. - Fold the sides of each foil over the mixture and roll the top down to seal tightly. - Place the foil packs on a baking sheet. Bake for 25-30 minutes, until the potatoes are tender and the steak is cooked to your liking. You can bake or grill these foil packs. Baking gives a steady heat, while grilling adds a smoky touch. When baking, set your oven to 400°F (200°C). If you grill, keep the heat medium-high. Cooking time can change based on how you like your steak. For medium-rare, aim for about 25 minutes. For medium, increase the time to 30 minutes. Always check the steak for your preferred doneness. To seal foil packs well, fold the edges tightly. This keeps steam inside and helps the food cook evenly. Make sure there are no openings. To ensure even cooking, spread the ingredients in a single layer. This helps everything cook at the same pace. Marinades can boost the taste of steak. Try a simple mix of soy sauce, garlic, and lemon juice for a tasty twist. Fresh herbs like rosemary and thyme offer bright flavors. Dried herbs work too, but fresh gives a bolder taste. Use what you have on hand for the best results. Pro Tips Use High-Quality Steak: Choose a well-marbled sirloin steak for the best flavor and tenderness. The fat will render during cooking, adding richness to the dish. Customize Your Veggies: Feel free to add or substitute other vegetables, such as bell peppers or zucchini, to enhance flavor and nutrition in your foil packs. Adjust Cooking Time: Cooking times may vary based on the size of your potato halves and steak cubes. Ensure potatoes are fork-tender and steak is cooked to your liking. Seal Tightly: Be sure to seal the foil packs tightly to keep the steam in, which helps cook the ingredients evenly and prevents drying out. {{image_2}} You can switch up the protein in your foil packs. Chicken works great instead of steak. Use boneless chicken thighs for juiciness. Cut them into bite-sized pieces, just like the steak. This way, chicken absorbs the garlic butter mix well. If you prefer a meat-free option, try tofu or tempeh. Both soak up flavors nicely. Cube them and treat them like steak. They offer a tasty twist for veggie lovers! Don’t stop at potatoes. You can add more vegetables to your packs! Bell peppers, sliced thin, add color and crunch. Onions bring sweetness when cooked. Mix and match to fit your taste. Seasonal veggies make these packs fun! In summer, use zucchini or corn. In fall, add carrots or squash. The options are endless, and they keep your meals fresh and exciting. Want some kick? Consider adding chili flakes for heat. A little goes a long way! If you like smoky flavors, smoked paprika is perfect. It gives your meal a deep, rich taste. For a bright twist, add lemon or citrus zest. The acidity cuts through the richness of the butter. Just sprinkle it on before sealing the foil packs. These little changes make your foil packs unique and flavorful! After you enjoy your Garlic Butter Steak & Potato Foil Packs, store leftovers in an airtight container. This keeps the steak and potatoes fresh. Place them in the fridge within two hours of cooking. They will last for up to three days. To reheat, you have two good choices: the oven or the microwave. The oven gives the best taste. Preheat it to 350°F (175°C). Place the foil pack on a baking sheet and heat for about 15 minutes. If you use the microwave, place the food in a safe dish. Heat in short bursts of one to two minutes until warm. You can freeze foil packs before cooking. Wrap them tightly in plastic wrap or foil. This helps keep out air and moisture. They will stay good in the freezer for up to three months. To thaw and reheat frozen packs, move them to the fridge overnight. This allows them to defrost slowly. Once thawed, follow the reheating steps above to enjoy your meal! Yes, you can use frozen steak! Just remember to adjust cooking time. If your steak is frozen, add about 10-15 minutes to the cooking time. Check the steak with a meat thermometer. It should reach 145°F for medium-rare. This ensures it's safe to eat. These foil packs pair well with many sides. Here are some suggestions: - Steamed broccoli adds a fresh crunch. - Caesar salad gives a nice crispness. - Garlic bread complements the flavors perfectly. - Grilled corn on the cob is a fun, seasonal choice.
