Ingredients:
- 3-4 large Yukon Gold potatoes (approx. 900g), peeled and sliced 1/8 inch thick
- 1.5 cups finely grated Parmesan cheese
- 2 tbsp extra virgin olive oil
- 1 tsp garlic powder
- 1 tsp kosher salt
- 0.5 tsp cracked black pepper
- 1 lb lean ground beef (90/10)
- 1 small yellow onion, finely diced
- 3 cloves garlic, minced
- 2 cups fresh baby spinach, chopped
- 0.5 cup whole milk ricotta cheese
- 1.5 cups shredded Mozzarella cheese
- 1 tbsp fresh parsley, chopped
Instructions:
- Preheat your oven to 400°F (200°C) and line a 13x18 inch rimmed baking sheet with high-quality parchment paper.
- Sprinkle 1 cup of the finely grated Parmesan cheese evenly across the parchment, forming a rectangular bed.
- Toss your 1/8 inch thick potato slices in a bowl with 2 tbsp olive oil, garlic powder, salt, and pepper. Arrange the slices on top of the Parmesan in overlapping rows, like shingles on a roof. Ensure each potato overlaps the next by at least half its width.
- Sprinkle the remaining 0.5 cup of Parmesan over the top.
- Bake the potato sheet for 20 minutes until the edges are deep mahogany and the potatoes are flexible.
- While the potatoes bake, brown the ground beef with diced onion and minced garlic in a skillet over medium-high heat. Drain all excess fat to prevent a soggy roll.
- Stir in the chopped spinach until wilted, then remove from heat and fold in the ricotta cheese and fresh parsley.
- Spread the beef mixture over the par-baked potato sheet, leaving a small border at the edges. Top with shredded Mozzarella.
- Using the parchment paper as a guide, carefully roll the potato sheet into a tight cylinder. Return to the oven for 10-15 minutes to melt the cheese and set the structure.
- Let it rest for 5 minutes before slicing with a sharp serrated knife.
