1-First Step: Prepare Your Ingredients Start by par-boiling the potatoes for 5 minutes to soften them up, then drain and let them cool for 10 minutes. This step ensures they cook evenly without turning mushy. Next, cut the steak into bite-sized pieces, making it easy to mix and eat later.

2-Second Step: Mix the Ingredients In a large bowl, combine the steak pieces, cooled potatoes, thinly sliced onion, 1 tablespoon of olive oil, 2 tablespoons of chopped fresh parsley, 1 tablespoon of minced garlic, and 1 tablespoon of Italian seasoning. Add salt and pepper to taste, then toss everything together until well coated. This mixing step builds flavor and makes sure every bite is seasoned perfectly, adapting easily to various dietary preferences like adding more veggies for extra nutrition.

3-Third Step: Assemble the Foil Packets Divide the mixture evenly among four 12
15 inch foil sheets, placing it in the center of each one. Top each packet with the cubed butter for a rich finish. Seal the foil packets securely by folding the edges over tightly, which helps trap steam and cook the food evenly inside.

4-Fourth Step: Cook the Foil Packets Now it’s time to cook. If you’re grilling, place the packets on a grill over high heat and cook for 8-10 minutes per side until the steak is done to your liking. For baking, preheat your oven to 425°F and bake for about 20 minutes. Check for doneness by carefully opening a packet the steak should be tender and the potatoes fork-soft, with options to adjust for different cooking methods based on your setup.

5-Final Step: Serve and Enjoy Once cooked, let the packets rest for a minute before opening to avoid steam burns. Serve them directly from the foil for a casual meal or plate them up for a nicer presentation.
