How to Make Garlic Butter Steak, Potato & Broccoli Foil Packets
Step 1: Preheat the Oven
Preheat your oven to 425°F. Tear off four large sheets of heavy-duty foil. If using regular foil, double-layer it to help prevent leaks.
Step 2: Par-Cook the Potatoes
Place the diced potatoes in a microwave-safe bowl with a splash of water. Cover and microwave for 4–5 minutes, just until they begin to soften. Drain well.
This quick step helps the potatoes finish cooking at the same time as the steak.
Step 3: Season the Steak and Potatoes
In a large bowl, toss the steak and potatoes with olive oil, garlic powder, salt, black pepper, and red pepper flakes, if using.
Step 4: Make the Garlic Butter
Melt 2 tablespoons of butter and stir in the minced garlic. Toss the broccoli florets with the garlic butter and the remaining 1 tablespoon of softened or melted butter.
Step 5: Assemble the Packets
Divide the steak, potatoes, and broccoli among the four foil sheets. Arrange the ingredients in the center of each sheet, keeping the portions in a fairly even layer.
Fold the foil over the food and seal the edges tightly, leaving a little space inside for heat to circulate.
Step 6: Bake
Place the packets on a rimmed baking sheet. Bake for 20–25 minutes, then carefully open one packet to check the potatoes and steak. If needed, reseal and bake for another 5–10 minutes, until the potatoes are tender and the steak is cooked to your preferred doneness.
Cooking time can vary depending on the size of the potato pieces and steak cubes.
Step 7: Add the Cheddar
Carefully open the packets, watching for escaping steam. Sprinkle shredded cheddar over each portion.
Leave the packets open and bake for another 2–3 minutes, or until the cheese melts. Serve directly from the foil or transfer everything to plates.
Tips for the Best Foil Packets
- Cut the potatoes into small, even pieces so they cook through.
- Par-cook the potatoes before assembling for more consistent results.
- Keep the ingredients in a single layer when possible.
- Seal the foil packets tightly to hold in steam and juices.
- Open packets carefully; hot steam can escape quickly.
- Add the cheese near the end so it melts without becoming oily or overcooked.
Can I Grill the Foil Packets?
Yes. Place sealed packets on a preheated grill over medium heat and cook for about 20–30 minutes, turning once halfway through. Check that the potatoes are tender and the steak is cooked as desired. Open the packets carefully and add the cheddar for the final few minutes.
Delicious Variations
Use a Different Steak Cut
Sirloin works well as a more budget-friendly option. Cut it into even cubes so it cooks at a similar rate.
Add More Vegetables
Sliced bell peppers, mushrooms, or onions can be added to the packets. Cut them into pieces similar in size so they cook evenly.
Make Them Spicier
Add extra red pepper flakes or a pinch of cayenne to the seasoning.
Change the Cheese
Try Monterey Jack, Colby Jack, or a cheddar blend instead of sharp cheddar.
Make-Ahead Tips
Cut the steak and vegetables and prepare the garlic butter several hours ahead. Refrigerate the ingredients separately, then assemble the foil packets just before cooking.
For food safety, keep raw steak refrigerated until you’re ready to cook. Don’t leave assembled raw packets at room temperature.
Storage and Reheating
Remove leftovers from the foil and store them in an airtight container in the refrigerator for up to 3 days.
Reheat in a covered oven-safe dish at 350°F until warmed through, or microwave in short intervals. The steak may cook further during reheating.
Frequently Asked Questions
Can I skip par-cooking the potatoes?
You can, but the potatoes may take longer than the steak to become tender. If skipping this step, cut them into smaller pieces and expect to extend the cooking time.
Can I use frozen broccoli?
Fresh broccoli gives the best texture. If using frozen broccoli, thaw it and pat it dry first to reduce extra moisture in the packets.
How do I know when the steak is done?
Check a few cubes with an instant-read thermometer, since doneness depends on their size and your preference. Avoid relying only on the outside color.
Can I prepare these without foil?
Yes. Arrange the ingredients in a covered baking dish. The cooking time may vary, so check the potatoes and steak as they cook.
Pro Tips
Dice the potatoes evenly and par-cook them before assembling. Keep the foil packets sealed while baking, then open them carefully and add the cheddar at the end for a melty, cheesy finish.
