Ingredients

• 43 ounces canned whole peeled plum tomatoes (from a 28-ounce can and a 15-ounce can)
• 3 garlic cloves, finely chopped
• 3 tablespoons extra-virgin olive oil
• Coarse salt and ground pepper
• 1 large egg yolk
• 1 1/2 cups part-skim ricotta cheese, room temperature
• 1 box (12 ounces) no-boil lasagna noodles
• 1/2 pound fresh mozzarella, shredded
• 1/4 cup grated pecorino or Parmesan cheese

Directions

• Preheat oven to 400 degrees. In a food processor, pulse tomatoes until coarsely pureed. In a large deep skillet, bring tomatoes, garlic, and oil to a boil. Season with salt and pepper. Reduce to a simmer and cook on medium until thickened, about 12 minutes (you should have 5 cups marinara sauce).
• Meanwhile, in a medium bowl, mix together egg yolk, ricotta, and 1/2 teaspoon each salt and pepper.
• Carefully pour sauce into a heatproof bowl and return 3/4 cup to skillet; spread sauce evenly. Add a single layer of noodles, breaking them up to fit. Top with half the ricotta mixture, spreading evenly. Follow with a second layer of noodles, then 1 1/2 cups marinara. Add a third layer of noodles, then remaining ricotta mixture. Follow with a final noodle layer, then remaining sauce. Sprinkle mozzarella and pecorino over top.
• Bake lasagna until golden and bubbling, 30 to 35 minutes. Let stand 10 minutes before serving.
