Ingredients

• 1 1/2 pounds thinly sliced beef steak – Sirloin or round steak works beautifully because they cook quickly while staying tender and juicy.
• 2 large yellow onions, thinly sliced – The onions soften and caramelize during baking, adding sweetness and deep savory flavor.
• 1 1/2 pounds baby potatoes, halved – Potatoes make the meal hearty and absorb all the delicious juices from the beef and seasoning.
• 3 tablespoons olive oil – Helps roast the potatoes evenly and keeps the beef moist.
• 2 teaspoons steak seasoning – Adds bold flavor with garlic, pepper, herbs, and spices.
• Salt and black pepper, to taste – Enhances the natural flavors of the ingredients.
• Nonstick cooking spray (optional) – Prevents sticking and makes cleanup even easier.

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C). This temperature is ideal because it allows the potatoes to become tender while helping the beef cook perfectly without drying out.

Step 2: Prepare the Ingredients

Wash and halve the baby potatoes. If using larger potatoes, cut them into 1-inch chunks for even cooking. Thinly slice the onions and steak if not already prepared.

Place the potatoes, onions, and beef into a large mixing bowl.

Step 3: Season Everything

Drizzle the olive oil over the ingredients. Sprinkle with steak seasoning, salt, and black pepper. Toss everything together until the beef, onions, and potatoes are evenly coated.

This step ensures every bite is packed with savory flavor.

Step 4: Assemble the Foil Packets

Tear off large sheets of heavy-duty aluminum foil. Lightly spray each sheet with nonstick cooking spray if desired.

Divide the beef mixture evenly among the foil sheets. Fold the foil tightly around the ingredients, creating sealed packets to trap steam and juices during cooking.

Step 5: Bake

Place the foil packets on a baking sheet and bake for 30–40 minutes, or until the potatoes are fork-tender and the beef is fully cooked.

Cooking time may vary depending on the thickness of the potatoes and steak slices.

Step 6: Serve and Enjoy

Carefully open the foil packets because hot steam will escape. Serve immediately while hot and juicy.

Pro Tips for the Best Foil Packet Dinner

• Slice Potatoes Evenly: Uniform potato pieces ensure even cooking.
• Use Heavy-Duty Foil: Prevents tearing and keeps juices sealed inside.
• Don’t Overcook the Beef: Thin steak cooks quickly, so check around the 30-minute mark.
• Add Extra Vegetables: Bell peppers, mushrooms, carrots, or zucchini work wonderfully.
• For Extra Flavor: Add minced garlic or a small pat of butter before sealing the packets.
