Creamy Spinach and Mushroom Lasagna

This is sure to become a family favorite. Best of all, it’s freezer-friendly and can also be made ahead of time!

Most of my recipes here can be made in 30 minutes or less and are basically effortless. But this is one of the few recipes that takes some time and a little bit of effort – but I promise you, it’s worth it.

After all, this recipe is enough to feed an army, can be assembled ahead of time, and is freezer-friendly. Triple win.

But the mushroom cream sauce alone is reason enough to whip this up. A cream sauce so good, I may just have to make a soup out of it.

But that’s for later. This lasagna here – well, you have 3 layers of this epic cream sauce along with an abundance of spinach and all that cheesy goodness in between.

And yes, I mentioned cutting down on carbs with our upcoming wedding but with yesterday’s salad, we all need a little bit of balance, no?

Now this is a meatless dish but feel free to add in your desired protein between the layers – ground turkey, Italian sausage, leftover chicken – it’s up to you.

But save some of the leftovers for later because this is just one of those dishes that tastes even better the very next day!

Instructions

• Preheat oven to 350 degrees F.
• To make the sauce, melt butter in a saucepan over medium heat. Add garlic, mushrooms and onion. Cook, stirring occasionally, until tender, about 3-4 minutes. Whisk in flour until lightly browned, about 1 minute.
• Gradually whisk in milk, and cook, whisking constantly, until slightly thickened, about 2-3 minutes. Stir in basil, oregano and nutmeg until fragrant, about 1 minute; season with salt and pepper, to taste; set aside.
• In a large pot of boiling salted water, cook lasagna noodles according to package instructions.
• Spread 1 cup mushroom sauce onto the bottom of a 9×13 baking dish; top with 3 lasagna noodles, 1/2 of the ricotta cheese, 1/2 of the spinach, 1 cup mozzarella cheese and 1/4 cup Parmesan. Repeat with a second layer. Top with remaining noodles, mushroom sauce and cheeses.*
• Place into oven and bake for 35-45 minutes, or until bubbling. Then broil for 2-3 minutes, or until top is browned in spots. Let cool 15 minutes.
• Serve, garnished with parsley, if desired.
