Kicking Monday off with my White Pesto Spinach Lasagna. Simply the BEST. Layers of creamy cheese bechamel sauce with basil pesto, spinach, and caramelized mushrooms. This dinner is always a favorite with our Christmas crew. It’s a great meal for entertaining, just make it ahead of time, and bake it off before guests arrive. Perfect for December!

In almost every interview, I’m asked what my go-to menu for entertaining is. I always say the very same thing, lasagna. And not just one lasagna, but two. One more classic lasagna with Bolognese sauce. And then a white lasagna that’s always extra cheesy.

I figured it was probably time I share BOTH of my go-to lasagna recipes for holiday entertaining. I might be in NYC today, but I’m already planning for our family Christmas in t-minus 2 weeks. Can you believe Christmas Eve is exactly two weeks from today? I really wish we had an extra week or two. So very behind on my Christmas shopping. I have a feeling this going to be the year of last-minute gift shopping…and it might be slightly stressful.

Anyway, back to this white lasagna.

I’ve made many variations of this (have you tried my butternut squash version?), but this is the fall back recipe I always rely on. It simply cannot be beat, and every time I make it, I love it that much more. It’s just so good.

First, the mushrooms. Now if you don’t like mushrooms, you don’t have to add these. But right now I’m on huge mushrooms kick, and absolutely loving them. I caramelized them in a little butter to make them extra delicious.

Next, the cream sauce, or bechamel as it is so fancifully called. This is creamy, loaded with cheese, and honestly the best thing to ever be tossed with pasta. I used a mix of melty Raclette and nutty parmesan cheese, and seasoned it with a little garlic and oregano. Beyond good.

The final layer of flavor is the pesto swirled ricotta. I love using pesto to bump up the flavor of my dishes. It’s perfect for adding a fresh basil flavor to this white lasagna.

Now we layer. To make things easier and quicker, I LOVE using no boil lasagna sheets. In my honest opinion, I think these are just as good as fresh pasta and so much easier. No boiling water, draining, or worrying about your noodles sticking together and tearing. Cool. Cool. Love that.

Layer the cheese sauce, noodles, pesto ricotta, mushrooms, and spinach. It’s three layers of all the best ingredients that bake up into a lasagna that’s mouth wateringly good.

I make this, along with my meaty lasagna, every single year for my family when they all arrive before Christmas. Us girls normally prefer the white, while the boys devour the red. I serve these lasagna with my favorite pomegranate spinach salad…shall I share? It’s simple. I’ve also been making this brussels sprout salad a lot too. Oh, and don’t forget some crusty bread.

Perfect family dinner that feeds everyone.

Also, as I mentioned, I’m in NYC today for a fun holiday party I’m hosting with Harry and David. I’ll be sharing a ton on Instagram stories, so be sure follow along.

Lastly, for those of you who are wondering, my red lasagna is coming next week. Stay tuned, it’s my brothers favorite!

    5. Spread 1/4 of the cheese sauce in the bottom of the prepared baking dish. Top with 3-4 lasagna sheets. Spread with 1/2 the ricotta cheese mixture, another 1/4 of the cheese sauce, and half of the mushrooms. Place another 3-4 lasagna noodles on top and then top with the remaining ricotta cheese mixture, another 1/4 of the cheese sauce, and the remaining mushrooms. Add the remaining lasagna noodles and pour the remaining cheese sauce over top. Top with a 1/2 cup of parmesan cheese. Bake uncovered for 45 minutes or until the top has bubbled up and browned a bit.
