Instructions:
- Preheat your cooking method:
- If baking, preheat your oven to 425°F (220°C).

- Prepare the ingredients:
- Cut the sirloin steak into 2-inch chunks and the baby potatoes into quarters.

- Season the steak and potatoes:
- In a large mixing bowl, combine the steak, potatoes, minced garlic, Italian seasoning, onion powder, olive oil, salt, and pepper.

- Assemble the foil packets:
- Tear off four 12×12-inch sheets of aluminum foil.
- Divide the steak and potato mixture evenly among the foil sheets.
- Optionally, add a small pat of butter on top of each portion for extra richness.
- Seal the foil packets:
- Fold each foil packet by bringing two opposite sides together and rolling down to seal tightly.
- Fold in the remaining two sides, ensuring there are no gaps for steam to escape.
- Cook the foil packets:

- Serve and enjoy:
