In a large mixing bowl, combine ricotta, cottage cheese, Italian blend cheese, spinach, eggs, salt and pepper until well combined. Spread half of one jar of marinara on the bottom of a 9x13-inch baking dish.
Top sauce with 5 lasagna noodles so all of the sauce is covered.
Spread half the cheese and spinach mixture over pasta and spread evenly. Place 6 slices of provolone cheese over the cheese and spinach mixture. Sprinkle on 1/2 cup mozzarella cheese.
Repeat layers.
Top with half a bottle of marinara.
Layer on 5 more lasagna noodles. Top with remaining marinara and top with remaining mozzarella cheese.
Cover with foil and bake for 60 minutes.
Remove from oven and remove foil.
Garnish with basil and parmesan cheese, if desired.
Notes
To make into a FREEZER MEAL: After you prepare the lasagna, cover it well with foil. Freeze before cooking, thaw for 24 hours in the fridge, and then bake as directed. We used store bought marinara but homemade sauce will also work for this recipe.
