Easy Vegetable Lasagna with White Sauce (Stouffer’s Copycat)

What is this Stouffer’s Vegetable Lasagna Recipe?

This is a somewhat iconic dish that many of us have had at one point or another.  Our copycat recipe includes homemade sauce and filling but none of the preservatives and allows you to easily customize to your liking:  want extra carrots?  Not a fan of broccoli?  We’ve got you with the perfect way to make it your own.  

Our version is easy to scale (make a few trays to freeze, give to friends or family, take to a potluck, etc).  Give it a try and let me know what you think.

Ingredients in Easy Vegetable Lasagna with White Sauce?

Begin with some regular lasagna noodles, for this dish we are using boil and bake noodles (ie, not oven ready noodles which will end up too dry for this version). It takes a bit more time; however, in the end it will make for a much better final dish.

  • For the sauce you will need:
    • Butter, use whatever you like, I used olive oil butter
    • All purpose flour
    • Milk- use whatever milk you prefer, whole, 2 percent, almond, etc
    • Kosher salt
    • Nutmeg
  • For the filling you will need
    • Shredded carrots: feel free to buy pre-shredded carrots to save time or great them yourself
    • Fresh spinach- cut off any tough stems if you are using regular instead of baby spinach
    • Fresh broccoli
    • Onion, use white, yellow or sweet
    • Grated parmesan cheese (the kind that often comes in a green can)
    • Mozzarella cheese- you can use pre-shredded or shred your own
    • Garlic powder
    • Egg
  • For the topping, you will need
    • Plain breadcrumbs, regular, not panko, etc
    • Butter, again, whatever type you like

Can I make Stouffer’s Vegetable Lasagna Recipe with White Sauce in advance?

To make in advance, assemble the dish up until the point of baking.  If you plan to have the lasagna later that day or the next, simply assemble the dish to that point and then bake as directed, storing in the fridge until you are ready to cook.

To make a tray to freeze for later, assemble all the ingredients and tightly line the tray with foil.  Freeze the dish at this point before baking.  When you are ready to bake the lasagna, remove from the freezer the night before and allow to defrost in the refrigerator overnight.  Thirty minutes to an hour before baking, remove to the counter (out of the refrigerator) and then bake as directed above.  Frozen Stouffer’s Vegetable Lasagna should keep well for up to three months after freezing.  This makes it a great dish to double or triple to have extras for another night, after a baby or meal-swapping with friends or family.

  • If you want to keep the veggie vibe going, this Creamed Spinach dish keeps the cozy-cheesiness going right along with the fresh veggies.
