Even after calculating the nutritional info about 14 times I still can’t believe that this creamy, cheesy lasagna is under 400 calories a serving.
The trade-off for all this deliciousness is that it takes some time to cook up and assemble the component parts. No-cook lasagna noodles help speed the process – and reduce the amount of noodles in the dish. This is a favorite of mine to prepare on weekends, bake on a busy weeknight, and then enjoy the leftovers all week long.
This is a super hearty option for Meatless Monday or any other night of the week. Serve it with a light salad on the side (it really is filling) for a comforting, healthy Autumn meal.
Ingredients
- 12 no-boil lasagna noodles (1/2 lb.)
- 4 oz Parmesan cheese, shredded, divided
- 8 oz light mozzarella cheese
- 4 c nonfat milk
- 1/2 c light butter
- 1/2 c flour
- 1/2 tsp ground nutmeg
- salt and freshly ground black pepper
- 3 garlic cloves, minced
- 3 tbs chopped parsley, divided
- 1 tbs chopped fresh thyme leaves, divided
- 2 tbs olive oil, divided
- 2 medium leeks, sliced into thin rings
- 1-1/2 lbs portabella mushrooms, sliced
- 1/2 lbs shiitake mushrooms, stemmed and sliced
Instructions
Place the noodles in a container of hot water to soften while preparing the filling.
Preheat oven to 375F.
Combine mozzarella and 2 oz Parmesan in a small bowl and set aside.
Make the Béchamel Sauce
In a medium saucepan, bring milk to a simmer over medium heat.
Heat butter in a large saucepan over medium heat. When melted, add flour and cook, stirring, until fragrant and beginning to turn golden, about 2 minutes.
Add warm milk to roux and whisk until smooth.
Add nutmeg and season to taste with salt and pepper.
Continue to simmer, stirring, until sauce thickens enough to coat the back of a spoon.
Remove from heat and stir in garlic, 1/2 the parsley and a pinch of thyme. Set aside.
Prepare the Mushrooms
Heat 1 tbs oil in a large pan.
Add leeks and cook, stirring occasionally, until beginning to turn golden, about 3 minutes. Transfer leeks to a bowl and set aside.
Heat remaining tablespoon of oil and add mushrooms. Season to taste and cook, stirring occasionally, until mushrooms release their juices and soften, about 5 minutes.
Stir in leeks and remaining thyme. Set aside.
Assemble the Lasagna
Spoon a small amount of béchamel in the bottom of a 13x9 baking dish. Arrange 3 noodles across the dish.

Spread 1/3 of the mushroom mixture atop the noodles.

Pour about 1/2 cup béchamel over the mushrooms and sprinkle with 1/4 of the cheese.

Repeat twice more then lay the final three noodles across the top. Pour remaining sauce over the top and sprinkle with remaining cheese.

Cook immediately or store the lasagna up to two days in the refrigerator. Let sit at room temperature 1 hour before baking. Alternatively, you can freeze the uncooked lasagna up to 3 months.
Bake the Lasagna
Bake lasagna until browned and bubbling, about 45 minutes.
If frozen, thaw in the refrigerator overnight or baked straight from the freezer for 1 3/4 hour, covered for the first hour.
Sprinkle with remaining 1 tbsp. parsley and let sit at least 15 minutes before slicing.

I don’t think to use leeks very often, even though they are so tasty. Your lasagna looks amazing, and of course I love all the veggie filling. Yum!
This dish looks so creamy and delicious! Never made lasagna with béchamel sauce and would love to try this one! Pictures are stunning!
Mmmm… I love Béchamel in lasagna even more than tomato-based sauce. I hope you can give it a try!
Looks delicious. I can’t wait to try it. Freezing it in individual meal-sized portions will make life oh-so-delicious this fall. Thanks!
Thanks so much, Jerri! Freezing individually is brilliant! I’m going to do that next time so I can cook them up in our little toaster oven and not worry about reheating the big guy.
Right up my street 🙂 Love all things mushroom!
Mmmm…. I love mushrooms, too! Last night we made a mushroom bourguignon that I’ll share soon.
Wonderful! I made this recipe over the weekend. I was going to freeze half, but we loved it so much we ate the whole thing a few days in a row. Ha! Now will have to make it again.
I made it dairy free, using coconut milk instead of the milk. Also, I made cashew cheese to replace the mozarella. I substituted ground beef for the shiritake mushrooms.
I did have trouble with the no-boil noodles. They all stuck together. So next time I will just put in the dish dry, then bake, or use the traditional style noodles.
Findnig this post. It’s just a big piece of luck for me.
This looks absolutely delicious! I just wanted to let you know that I have a food photo submission site at Simply Creative Recipes and I am linking to this post if you don’t mind. You are welcome to submit your recipes at my site if you’d like.
Thank you, Alyssa! Love the site!
