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!

  1. How much lasagna noodles do we actually need? Different brands have different amounts and I don’t want to end up not having boiled enough sheets (I use normal lasagna noodles as I don’t like the texture of the no boil ones), and then having to make extra, or making to much and not knowing what to do with the rest.

    1. HI Khloe! You need 1 pound (12 ounces) of noodles. Please let me know if you have any other questions. I hope you love this recipe! Thank you! xTieghan

  2. I made this last night, for Christmas dinner. I veganized it: the cheeses and the milk. It still turned out perfectly!! Your recipes are very precise, as well as beautiful. Thanks for your hard work!! ?

    1. HI! I am sure Ziti will be delicious! Fun idea! Please let me know if you have any other questions. I hope you love this recipe! Thank you and Merry Christmas! xTieghan

      1. Would you bake it, then freeze? I’d like to make ahead for a trip to the cabin but not sure wether to freeze it before or after baking?

        1. Hey Jacquie,
          You would want to freeze before baking. I hope you love the recipe, please let me know if you give it a try! xTieghan

  3. This sounds delicious! Going to make this for Christmas dinner. My family are big meat eaters though. Can you recommend a good “Holiday” protein entree that goes great with this?

    Wonderful recipe. Can I add more vegetables ( maybe some sautéed zucchini) or would this make the lasagna too wet?

    1. Hi Molly! Additional vegetables will be delicious. Love the sound of sautéd zucchini. I think that will be great! Please let me know if you have any other questions. I hope you love this recipe! Thank you and happy holidays! xTieghan

  5. I plan on making this recipe for a cabin getaway weekend with a group of my friends. I’m so excited to try it out, as it looks amazing!
    Question: Can I make it ahead of time and assemble it? Then bake it say 2-3 days later? Or will it ruin the integrity of the meal? I want it to be delicious! But would love to avoid prep-work the day of so I can enjoy my time 🙂

    1. Hi Kathleen! Yes! You can certainly make ahead, then bake a few days later. That works great and I do it all the time. Please let me know if you have any other questions. I hope you love this recipe! Thank you! xTieghan

    1. Hi Chanel! I would recommend using roasted chicken with Italian seasoning. That will be delicious! Please let me know if you have any other questions. I hope you love this recipe! Thank you! xTieghan

  6. This looks great! Thinking of making it today and adding some shredded chicken? What are your thoughts on that?
    Thanks! 🙂

    1. Hi Bianca! I am sure shredded chicken will be a great addition! Please let me know if you have any other questions. I hope you love this recipe! Thank you! xTieghan ??

    1. Hi Norma! Yes, you can freeze this for up to 4 months. Just be sure to cover it well to prevent freezer burn. Please let me know if you have any other questions. I hope you love this recipe! Thank you! xTieghan ???

  7. I mixed 2 tablespoons of flour with 4 tablespoons of sauce and added back into the sauce. I did that several times and it thickened up. Served to company last night and everyone raved about it! Having leftovers for dinner and looking forward to it!! Thank you for the recipe!
    Sara

  8. I am making this now and concerned about the sauce – it seems very thin! I had to use fontina cheese because my Publix didn’t have reclette. I have it in the refrigerator now hoping it will thicken up. What can I do if it doesn’t??

    1. Hi Sara! I wouldn’t worry about it. The sauce thickens greatly while baking. Please let me know if you have any other questions. I hope you love this recipe! Thank you! xTieghan

  9. 4 stars
    This was a great recipe – the bechamel sauce was fantastic. I used a mixture of fontina and gruyere in mine due to what was available at the store and will definitely make again. The lasagna was very spinach-y, so in the future, I might add more mushrooms and add artichokes and/or onion and/or chicken. Everyone loved the cheesiness!

    1. Thank you so much Claire! So glad to hear that everyone enjoyed this recipe! Also, hope you love it more with some mushrooms and artichokes! xTieghan

  10. Sorry if someone else addressed this:
    Step 2 says “heat oil in skillet over medium heat”
    Step 3 says “reduce heat to medium”
    Um, it was already at medium. Please clarify.
    (Make the pesto bolognese last weekend and my husband loved it.)

    1. Hi Joyce! Yes, please keep the skillet at medium heat, recipe adjusted. Please let me know if you have any other questions. I hope you love this recipe! Thank you! xTieghan
