# How to Make It:

01 - Preheat the oven to 375° F. Butter a 9x13 inch baking dish.
02 - 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.
03 - In a medium bowl combine the ricotta, provolone, spinach, pesto, and egg. Season with pepper.
04 - 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 until all the sauce has been used. Top with the remaining 1/2 cup of parmesan.
05 - 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.

# Additional Tips:

01 - To Make Ahead: Prepare the lasagna through assembly, but do not bake. Cover and store in the fridge for up to 2 days. To bake, remove from the fridge while the oven preheats, then bake as directed.
02 - To Freeze: Prepare the lasagna completely, but do not bake. Cover and wrap tightly in foil, then plastic wrap. Freeze for up to 3 months. To thaw: thaw overnight in the fridge. To bake from frozen, remove plastic wrap and bake, covered at 375°F for 1 hour or until center is hot, then uncovered for 40-45 minutes until browned.
