Ragu Sauce (See below)
Medium White Sauce
Shredded Mozzarella or Italian Cheese Blend
1/2 cup Bread Crumbs
1/2 cup Parmesan Cheese
Start with a good ragu sauce. If you don't want to go through the trouble of making one from scratch, brown 1 lb ground meat, add 1 jar of spaghetti sauce.
Cook lasagna noodles according to package directions. (We prefer whole wheat noodles.) Place noodles on wax paper or aluminum foil to prevent them from sticking together.
Make Medium White Sauce:
2 Tbsp butter melted in pan
add 2 Tbsp flour and cook until bubbling.
add 1 cup milk and salt and pepper to taste. Boil and stir continuously until thick (about 1 min).
Pour a few Tbsp of ragu on the bottom of a greased 13x9" pan. Arrange half of lasagna noodles on the bottom of pan. Layer half of ragu, white sauce and mozzarella. Repeat. Top with bread crumbs and parmesan cheese. Cook at 375º for 1 hour.
