  • 1.Preheat the oven to 375° F. Butter a 9x13 inch pan.
    2. In a medium saucepan, melt together the butter, garlic, sage, rosemary, fennel, and a pinch of red pepper flakes. Cook 3-4 minutes, until the butter is lightly browning. Whisk in the flour and cook for 1 minute. Add the milk and broth. Season with salt, and pepper. Bring to a boil. Stir in the Gruyère/fontina cheese, 1/2 cup of parmesan cheese, and the nutmeg. Stir until the cheese is melted and the sauce is smooth. Remove from the heat.
    3. In a medium bowl combine the ricotta, provolone, spinach, pesto, and egg. Season with pepper.
    4. Spread 1/4 of the cheese sauce in the bottom of the prepared baking dish. Top with 3-4 lasagna sheets. Spread with 1/2 the ricotta cheese mixture and another 1/4 of the cheese sauce. Repeat the layering. Repeat the layering until all the sauce has been used...don't stress about making it perfect. Top with a 1/2 cup of parmesan.
    5. Bake covered for 30 minutes. Uncover and bake another 15-20 minutes, until the top has bubbled up and browned a bit. Let stand 10 minutes before serving. Enjoy!


To Make Ahead: Prepare the lasagna through step 4, but do not bake. Cover and store the assembled lasagna in the fridge for up to 2 days. To bake, remove the lasagna from the fridge while the oven preheats, then bake as directed. 
To Freeze: Prepare the lasagna through step 5, but do not bake. Cover and wrap tightly in foil, then plastic wrap. Freeze for up to 3 months. To thaw: thaw the lasagna overnight in the fridge. To bake from frozen, remove the plastic wrap and bake, covered at 375 for 1 hour or until the center is hot. Remove the foil and bake another 40-45 minutes, until the top has browned. 
To Make Gluten Free: Use gluten free no-boil lasagna noodles and an equal amount of your favorite gluten free flour blend in place of the all-purpose flour. I recommend Cup4Cup gluten free flour
