Foil packs make dinner wonderfully straightforward. The steak, potatoes, seasoning, and oil all cook together in individual portions, so there is no separate pan for the meat and no pot required for the potatoes.
The flavor is classic and comforting without being heavy. Garlic brings savory depth, Italian seasoning adds herby notes, and onion powder rounds out the seasoning with a gentle sweetness that clings beautifully to the steak and potatoes.
This recipe is also easy to customize at the table. Serve each packet as it is, or add a small side salad, steamed green beans, or crusty bread to make the meal feel more substantial.

Ingredients You’ll Need
The ingredient list is short, but each item has an important job. Sirloin provides tender, beefy flavor, while baby potatoes become soft and creamy inside the sealed packets.
- Sirloin steak: Use 1 pound, cut into even 1-inch cubes. Uniform pieces help the steak cook consistently.
- Baby potatoes: Use 1 pound, quartered or cut into pieces no larger than about 1 inch.
- Olive oil: Three tablespoons help coat the potatoes and steak while carrying the garlic and seasonings across every bite.
- Garlic and seasonings: One tablespoon minced garlic, 1 teaspoon Italian seasoning, 1 teaspoon onion powder, 1 teaspoon kosher salt, and 1/2 teaspoon black pepper create the savory flavor base.
- Fresh parsley: Two tablespoons chopped parsley bring color and a fresh finish after baking.
Heavy-duty foil is helpful because it holds the ingredients securely and creates a tight seal. A rimmed baking sheet should always support the packets in case a little flavorful oil escapes during baking.

How to Make It Step-by-Step
Step 1: Heat your oven to 425°F. Tear off four large sheets of heavy-duty aluminum foil and place them on the counter, leaving enough room around each piece to fold and crimp the edges securely.
Step 2: Prepare the steak and potatoes so they are close in size. Cut the sirloin into 1-inch cubes, quarter very small baby potatoes, and halve or quarter larger baby potatoes; pieces that are too large may remain firm while the steak is already done.
Step 3: Add the potatoes to a large bowl with about 1 tablespoon of the olive oil, the minced garlic, Italian seasoning, onion powder, salt, and black pepper. Toss thoroughly so the seasoning reaches all the cut surfaces of the potatoes.
Step 4: Add the steak cubes and the remaining olive oil to the bowl. Toss again until the meat is evenly coated, taking care not to mash or break the potatoes.
Step 5: Divide the mixture evenly among the four foil sheets. Keep the ingredients in the center of each sheet, then fold the foil over the top and crimp the edges tightly so the packets are sealed and steam cannot easily escape.
Step 6: Set the packets on a rimmed baking sheet and bake at 425°F for 20 to 25 minutes. The potatoes should be fork-tender, and the steak should reach the doneness you prefer when checked with an instant-read thermometer.
Step 7: Remove the baking sheet from the oven and allow the packets to rest for a few minutes. Open them carefully away from your face because the trapped steam will be very hot, then sprinkle each portion with fresh parsley.
Chef’s Tips for Tender Steak and Potatoes
The most important detail is potato size. Keep every potato piece at about 1 inch or smaller so it has enough time to become tender during the 20-to-25-minute bake.
If your potatoes are particularly firm or larger than baby potatoes, microwave or parboil them for several minutes before assembling the packets. They do not need to be fully cooked; the goal is simply to give them a head start.
Steak thickness, potato variety, and individual oven temperatures can affect the final result. Rather than relying only on the clock, test a potato with a fork and check the steak with an instant-read thermometer.
For a little more browning, carefully open the packets near the end of cooking. You can also transfer the cooked contents to a hot skillet briefly, watching closely so the steak does not overcook.
Remember that steak can continue cooking from retained heat after the packets leave the oven. A short rest helps the juices settle, but do not leave the packets sealed for an extended time if you want to preserve your preferred steak doneness.
Serving Ideas and Variations
These foil packs are filling on their own, but a fresh side can balance the rich steak and potatoes. Try crisp greens with a light vinaigrette, roasted vegetables, or steamed green beans.
You can place the opened packets directly on plates for a rustic presentation. If you prefer a more polished dinner, transfer the steak and potatoes to a serving platter, spoon over any seasoned juices, and finish with parsley.
The provided seasoning combination keeps the recipe dependable and simple. Other versions may use garlic butter, Worcestershire sauce, rosemary, or thyme, but the olive oil method here gives the potatoes and steak a clean, savory coating without changing the core preparation.

Storage, Reheating, and Food Safety
Allow leftovers to cool promptly, then transfer the steak and potatoes from the foil into airtight containers. Refrigerate them and enjoy within a few days, reheating only the portion you plan to eat.
Reheat gently in a covered skillet or in the oven until warmed through. A gentle method helps prevent the steak from becoming dry, while a splash of water or a small drizzle of olive oil can keep the potatoes from feeling too firm.
Do not rely on foil alone for long-term storage, and do not reheat a sealed foil packet in the microwave. Always open the packet first and move the food to a microwave-safe dish if using a microwave.

Common Questions
Can I prepare the packets ahead of time? You can cut the steak and potatoes and mix the seasonings in advance, but assemble and bake the packets close to serving time for the best texture. Keep raw steak and prepared potatoes refrigerated until you are ready to cook.
Why are my potatoes still firm? They may have been cut too large, or they may be a firmer variety. Next time, cut them smaller or microwave or parboil them for several minutes before adding them to the foil.
Can I use a different cut of steak? Sirloin is the stated choice for this recipe because it offers a good balance of flavor and tenderness. If substituting another cut, cut it into the same 1-inch cubes and monitor doneness carefully.
How do I prevent overcooked steak? Check the steak before the full cooking time is complete, especially if your cubes are small. Open the packets carefully, check with an instant-read thermometer, and remember that the meat may continue cooking briefly after removal.

Easy Garlic Steak and Potato Foil Packs
Ingredients
Method
- Heat the oven to 425°F and tear off four large sheets of heavy-duty aluminum foil. Place the sheets on your work surface so the seasoned steak and potatoes can be divided evenly.
- Cut the sirloin into 1-inch cubes and cut the baby potatoes into similarly sized pieces. Quarter very small potatoes and halve or quarter larger ones so the potatoes cook at the same rate as the steak.
- Toss the potatoes with 1 tablespoon olive oil, minced garlic, Italian seasoning, onion powder, kosher salt, and black pepper. Add the steak and remaining 2 tablespoons olive oil, then toss until every piece is evenly coated.
- Divide the steak and potato mixture among the four foil sheets, keeping the portions near the center. Fold the foil over the food and crimp the edges tightly to form sealed packets.
- Place the sealed packets on a rimmed baking sheet and bake for 20 to 25 minutes. Check that the potatoes are fork-tender and use an instant-read thermometer to check the steak for your preferred doneness.
- Open each packet carefully because hot steam will escape. Let the steak rest for a few minutes, garnish with chopped parsley, and serve immediately.
Notes
