I love easy skillet lasagna recipes for their easy preparation and clean-up. Have you tried my French Onion Skillet Lasagna? Ever since I tried that recipe I knew I had to come up with another version and this Spinach Alfredo Lasagna is my new favorite -especially now that spinach is in season. But as you can make this with frozen spinach, you can prepare this easy one pot pasta dinner all year round.

Notes
- To make the pasta nut-free, you can use my nut-free Alfredo (pumpkin seeds or cauliflower). or use 7 oz silken or firm tofu instead of cashews, like my Spinach Artichoke Pasta Bake
- Miso substitute: and to make soyfree, use chickpea miso or 1 tablespoon more nutritional yeast.
- To make this Glutenfree, use Glutenfree lasagna or pasta
- For cheesier blend in 1/4 vegan cheese of choice with the cashew blend
Nutrition
Nutrition information is automatically calculated, so should only be used as an approximation.
Ingredients and substitutes:
- as for the pasta you can use 6 regular lasagna sheets or 8 no-boil lasagna sheets. Or use 2 cups uncooked flat style pasta of choice. Use gluten-free, if you want.
- the best alfredo lasagna – really any white lasagna – will always have plenty of garlic, mushrooms, and spinach, so I am using that trifecta. You can omit the mushrooms if you like.
- For the alfredo sauce, we blend soaked cashews, with some broth, lemon juice, and Italian herbs. See recipe notes for Nutfree options
- Nutritional yeast and miso paste add the “cheesy” flavor to our vegan alfredo. To omit nutritional yeast, double the miso and leave out the yeast
- A touch of balsamic vinegar adds both sweetness and acidity when sauteeing the mushrooms – a great addition!

Tips:
- This skillet lasagna recipe is perfect for using up those broken lasagna sheets you always get at the bottom of the pack. You can also use other flat pasta of choice
- If you do not have miso, add more nutritional yeast – the same goes the other way round.

Add oil to a large skillet over medium heat, then add garlic and cook until the garlic is starting to turn golden, then add in the spinach, salt, and pepper flakes, and mix well.
Once the spinach is wilted, take off heat, and remove the spinach from the skillet into a bowl. For frozen spinach, just cook until the excess water has dried out, but the spinach still has its vibrant color.

For the vegan white sauce (alfredo sauce), blend all of the ingredients until smooth then set aside. You can blend for a minute, then wait for 5 minutes, so that the blended cashews rehydrate, and then blend again so that the mixture will be smooth.
Now, heat oil in the same skillet, add the onion, mushroom, garlic, salt, and pepper, and cook until the onion is golden, 6-8 minutes. Stir occasionally in between.


Add in the balsamic vinegar, and mix in and cook for another 2 minutes. Then add your lasagna sheets, the water or broth, and about 3/4 of the blended alfredo sauce, and mix in to cover the skillet and cook for 12-14 minutes. Stir once in between. If the mixture is thickening too much, add in 2-4 tbsp more water or broth.

Once the lasagna sheets are cooked to preference, reduce the heat to low medium.

Distribute the spinach all over the skillet, and drizzle the remaining alfredo sauce all over as well, then cover and cook for two minutes, and take off the heat.

Let the skillet sit for a few minutes for the alfredo sauce to thicken a bit more, then serve with some extra pepper flakes on top if you like, or some toasted bread crumbs.

Make-ahead instructions:
- You can make the vegan alfredo sauce ahead of time and store it in the fridge.
- If you want to speed this up even more, prepare balsamic mushrooms and spinach garlic mix ahead of time and store in a container, then continue with step 5.












Looks so good 😊 any ideas for omitting /replacing mushrooms ??
Swap mushrooms with thinly sliced zucchini or yellow squash, eggplant, or other soft veggies you like. Or you can omit mushrooms entirely and make the dish otherwise as-is.
Just made this for dinner after seeing it on Instagram and damn, it’s good! So creamy, the perfect amount of garlic, the red pepper flakes add that little bite to it, and the broken lasagna is just luxurious. I don’t like mushrooms so I subbed in thinly sliced zucchini and it was delicious. I’ll definitely be making this again!
Awesome 🤩
Wow!! This was a winner. This is why I own all 3 of your cookbooks!! We have a cashew allergy in our house so I made it with the silken tofu substitute and it worked perfectly. Only thing is that it barely fed 3 of us … definitely not 6 servings in our house as a main dish. Will double it next time for left-overs and there will be many more next times!!
thank you so much. -wow – sounds like everyone really liked it
This dish was AMAZING. I hate mushrooms and I loved it! So did the fam! I would definitely double the recipe to feed a family of 5. Two of our kids weren’t home and thank goodness because there would have been a fight! Thanks for such an awesome recipe!!!
wow, thanks Lulu
Everyone loved it. The sauce was so rich, quite extravagant! Took much longer to cook the pasta than stated in recipe. I also think I’ll add .5 tsp of onion powder to the sauce for additional flavor.
The pans and stoves change the time. So definitely adjust.
This looks delicious, wondering how/if it could be adjusted in some way to make it with rice instead of pasta?
Add 3/4 cup washed rice. Instead of using cashew cream, use 1.( cups water or broth and cook partially covered over medium low for 15 mins. Check if the rice is cooked. Make the cashew cream mixture with 3/4 cup water and add that to the rice. Bring to a simmer and continue. .
I love making your recipes so much! The ingredients are so different from my norm so I’m so interested in how it will turn out and they are just fantastic each time, this was no different. The cashew alfredo sauce is just SO SO GOOD!!
Yay
Delicious! Will have to double the recipe next time because it was enjoyed so quickly.
Awesome!!!
This is heavenly and so easy to put together!! Will be making this again and again. Im gluten free and gluten free lasagna noodles cooked up just fine.
Nice
While mine did not look like Richa’s photos, this was spectacular! My husband said it was one of the best meals I’ve made in years. (And I cook from scratch a lot.) It’s luxurious, creamy, special.
I followed the recipe to the letter, but added peas (since for some reason I think of alfredo with peas). I suggest a longer cashew soak, and definitely do the blend/wait/blend suggestion. Makes a huge difference.
So, so, good.
Awesome
