To make sauce, melt butter over medium heat in heavy, 1 quart saucepan. Add flour and stir until well blended; cook until frothy. Add milk, stirring constantly with wire whisk as mixture comes to a simmer. Cook and stir until thickened (3-4 minutes). Chill while mixing other ingredients. Drain tomatoes. Place other cheese filling ingredients in 3-quart mixing bowl with tomatoes and garlic. Add 1 and 1/2 cups of cooled cream sauce and mix until well blended. Refrigerate, reserving 1/2-cup for later use.

Cook lasagna noodles according to package directions. Cool under cold water and drain. Place 3 lasagna noodles in a 9x13x2 lightly oiled baking dish, overlapping slightly. Spread 1 and 1/2 cups cheese filling over noodles; sprinkle with one cup mozzarella and 1/4 cup fontina cheese. Repeat pasta and cheese layering three more times; top with remaining three lasagna noodles. Spread 1/2 cup of reserved cream sauce over top and cover lightly with foil. Preheat oven to 350 degrees and bake for 1 hour. Remove from oven and keep warm at least 30 minutes before serving.

Serve topped with hot marinara and Parmesan cheese. (Can be refrigerated for a day before baking if desired)
