Layered crêpes with ragù and cheese baked into an Abruzzese dome is festive elegance. A high protein mediterranean dish perfect for family celebrations.
Whisk together eggs, flour, and milk until smooth; let rest for 15 minutes so the batter hydrates fully.
Heat a lightly oiled nonstick skillet over medium-low heat. Pour 1/4 cup batter and swirl to coat the pan, cooking each crêpe about 1 minute per side until just golden; repeat until all batter is used.
For the ragù, heat olive oil in a large pan over medium heat. Add chopped onion and sauté 3 minutes until translucent; add ground beef and pork, cook until browned, then stir in tomato sauce, salt, pepper, nutmeg, and basil. Simmer uncovered for 30 minutes, stirring occasionally.
Preheat oven to 375°F. Grease a round baking dish or deep pie pan. Layer crêpes, ragù, mozzarella, and Parmesan in sequence, repeating until all ingredients are used, finishing with cheese on top.
Bake for 40–45 minutes until bubbling and golden brown. Rest for 10 minutes after baking to help slices hold together. Serve warm, cutting wedges for each portion.
