Spinach Lasagna

• 2 tablespoons olive oil
• 6 large onions (2 white, 2 red, 2 yellow), halved and thinly sliced
• 6 cloves garlic, chopped
• 1 1/2 cups lowfat chicken or vegetable stock, divided
• 6 scallions, thinly sliced
• 1 tablespoon dried oregano
• 2 teaspoons salt (preferably sea salt), plus more to season
• 1 teaspoon freshly ground black pepper, plus more to season
• 9 whole-wheat lasagna noodles
• 2 packages (9 ounces each) frozen spinach
• 1 tablespoon salted butter
• 1 tablespoon all-purpose flour
• 1 egg
• 2 cups part-skim ricotta
• Grated zest of 1/2 lemon
• Olive oil cooking spray
• 1 cup grated Parmesan, divided

1. Heat oven to 375u0b0F. In a large saute pan over medium heat, heat oil. Add onions and garlic; toss to coat. Add 1 cup stock; cover and reduce heat; simmer until onions are soft, 20 minutes. Reserve 1/2 cup liquid. Add scallions, oregano, salt and pepper to onion mixture; increase heat to medium and cook, stirring, until liquid evaporates, 20 minutes. Cook noodles as directed on package; drain and blot dry. Cook spinach as directed on package; drain, squeeze dry, and season with salt and pepper. In a small saucepan over medium heat, melt butter. Add flour; stir until roux is brown, 2 to 3 minutes. Add remaining 1/2 cup stock to reserved liquid; whisk into roux until thick, 5 minutes. In a bowl, beat egg; stir in ricotta and zest. Coat a 9" x 13" pan with cooking spray; spread half of stock-roux mixture on bottom. Line pan with 3 noodles; layer on half of onion and ricotta mixtures, half of spinach and 1/3 cup Parmesan. Repeat layer with 3 noodles, remaining onion and ricotta mixtures and spinach, and 1/3 cup Parmesan. Top with remaining 3 noodles, half of stock-roux mixture and 1/3 cup grated Parmesan. Cover with foil; bake until light brown, 50 minutes. Reduce heat to 325u0b0F; remove foil and bake 15 minutes more. Let lasagna sit 15 minutes; serve.
