Preheat the oven to 375°F.
Cut the elk roast into 8 pieces, roughly 1 inch thick, and pound with a meat mallet to tenderize.
In a bowl, combine bread crumbs, Parmesan cheese, dried basil, oregano, garlic powder, salt, and pepper. In a separate bowl, beat the eggs with water. Place ½ cup of flour on a plate. Lightly dredge each piece of elk in the flour, shaking off excess, dip in the egg mixture, then coat in the breadcrumb mixture, pressing firmly to adhere. Set aside.
Heat a large skillet over medium heat and add the oil. Once hot, cook the breaded elk pieces 1–2 minutes per side until golden brown. Work in batches to avoid overcrowding.
Pour the spaghetti sauce into a 9x13-inch baking dish. Arrange the elk cutlets in the sauce and top each with a slice of fresh mozzarella. Spoon ricotta into the sauce and sprinkle with chopped basil.
Bake uncovered for 30 minutes, until the cheese is melted and the sauce is bubbly.
Serve the elk Parmesan over cooked pasta or wilted spinach and garnish with fresh basil.
