1. Preheat the oven to 400°F and, pull out a 9x 13 inch pan and set aside.

2. Spread a layer of the vegetable mixture over the noodles, followed by a thin drizzle of the béchamel sauce, a layer of the ricotta cheese mixture, and repeat the layers, ending with a layer of lasagna noodles and about 1 cup of béchamel sauce and a sprinkle of mozzarella cheese on top.

Frequently Asked Questions - FAQ

How do I prevent the top layer of cheese from burning? 

Cover the dish with aluminum foil while baking to stop the cheese on top of the lasagna from burning. Remove the foil during the last few minutes of baking to allow the cheese to brown and bubble.

Is there a substitute for ricotta cheese?

If you do not like ricotta cheese, you can substitute it with cottage cheese or a mix of mascarpone cheese and cream to achieve a similar creamy texture in your lasagna.

What's the best way to neatly slice Copycat Stouffer's Vegetable Lasagna? 

To make slicing easier, allow the lasagna to cool for a few minutes after removing it from the oven. Then, use a chef's knife or a serrated knife to cut through the layers, making sure you slice all the way through for a clean cut and perfect slice.

What can I serve my Stouffer's Veggie-Lovers Lasagna with?

There are many different side dishes that you can serve with your lasagna, but my top two favorites are garlic bread and a crisp green salad. I like to begin my meal with a simple, fresh salad with a vinaigrette dressing to contrast the richness of the lasagna.
