Directions

  1. To prepare sauce, heat olive oil in a large saucepan. Add onion and garlic; cook until soft and translucent, but not brown.
  2. Add tomatoes, tomato paste, sugar, salt, oregano, basil, crushed red pepper and black pepper; stir well. Bring to a boil; simmer, uncovered, 30 minutes. Let cool slightly.
  3. Preheat oven to 375F.
  4. To prepare lasagna, combine ricotta cheese, spinach and egg in a large bowl; mix well.
  5. Coat the bottom of a 13 x 9-inch baking pan with a third of the tomato sauce. Cover sauce with 3 noodles without overlapping (break noodles to fit), half the ricotta mixture and half the mozzarella slices. Add half the remaining sauce, 3 noodles, remaining ricotta mixture and remaining mozzarella. Top with remaining 3 noodles, remaining sauce and Parmigiano Reggiano cheese. To make ahead of time, cover with foil and refrigerate 6 to 8 hours or overnight.
  6. Place pan on baking sheet. Bake, uncovered, 40 minutes, or until bubbly. Let stand about 15 minutes before cutting into squares.
