– 1 lb baby potatoes, halved
– 4 tablespoons unsalted butter, melted
– 4 cloves garlic, minced
The main ingredients bring bold flavors to this dish. Sirloin steak gives you rich, juicy bites. Baby potatoes add a nice texture and soak up the garlic butter. The melted butter keeps the steak tender and moist. Garlic adds a wonderful aroma and flavor.
Seasoning and Garnish
– 1 teaspoon dried rosemary
– 1 teaspoon dried thyme
– Salt and pepper to taste

Seasoning makes a big difference. Dried rosemary and thyme give depth to the dish. Salt and pepper enhance all the flavors. Fresh parsley adds a pop of color and freshness when you garnish. This mix of herbs creates a delightful aroma as it cooks.
Optional Ingredients
– 1 tablespoon olive oil
– 1 cup cherry tomatoes, halved
Olive oil helps coat the potatoes well. It adds a touch of richness to the mix. Cherry tomatoes bring a burst of sweetness. They also add a nice color contrast. Feel free to use them for an extra flavor boost!

Tips & Tricks
Cooking Method Tips
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.
Foil Pack Assembly Tips
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.
Enhancing Flavors
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.
Variations
Protein Alternatives
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!
Adding Vegetables
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.
Flavor Enhancements
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!
Storage Info
Refrigeration
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.
Reheating Instructions
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.
Freezing Foil Packs
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!
FAQs
Can I use frozen steak for the recipe?
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.

Preheat your oven to 400°F (200°C). Alternatively, you can prepare these foil packs on a grill.
In a small bowl, mix together the melted butter, minced garlic, dried rosemary, dried thyme, salt, and pepper. Set aside.
In a large bowl, toss the halved baby potatoes with olive oil, salt, and pepper until evenly coated.
In the same bowl, add the cubed sirloin steak and half of the garlic butter mixture. Toss to coat the steak and potatoes well.
Cut four large pieces of aluminum foil (about 12x12 inches each). Dividing the mixture evenly, place the seasoned steak and potato mixture in the center of each piece of foil.
Top each pack with a handful of halved cherry tomatoes. Drizzle the remaining garlic butter mixture over the entire contents of each pack.
Fold the sides of each piece of foil over the mixture and roll the top down to seal the pack tightly, ensuring there are no openings for steam to escape.
