🥣 Ingredients and Notes
Casserole Layers
Yukon Gold Potatoes: You can also use russet potatoes and other varieties, but I find that the Yukon Golds are creamy and buttery and compliment the other ingredients nicely.
Cauliflower: This helps add dimension and depth to the casserole while adding a little more vitamins and nutrients.
Spinach: Brings a beautiful green accent color to the dish, and works really well with the creamy sauce.
Vegan Cream Sauce Ingredients
Dairy-Free Milk: I like to use Almond Milk but you can use another dairy-free milk alternative like coconut milk, cashew, oat milk, or soy milk work well too. I prefer unsweetened almond milk in this recipe.
Onion: Always a good ingredient to use in casseroles because it provides delicious flavor.
Vegetable Stock: Organic low sodium vegetable broth from Whole Foods is what I like to use. But if you don’t have stock, you can also use water.
Spices and Herbs: Can’t go wrong adding garlic, salt and pepper to bring out the flavor.
Cashews: Be sure to use raw unsalted cashews for the sauce. When soaked or boiled cashews add a creamy element to the sauce and also helps it to thicken.
Nutritional Yeast: This brings that umami cheesy flavor to the sauce.
Breadcrumb Crust:
To make this fantastic breadcrumb crust you’ll need gluten-free panko breadcrumbs, walnuts to help get that crunchy crust, hemp seeds (optional, and Italian Seasoning to tie all the flavors of the entire dish together.
📋 Step by Step Instructions
Step 1: Preheat the oven to 400 F. Thinly slice the potatoes, and line the bottom of the baking dish with one layer of the potatoes.
Step 2: Cut the cauliflower into thin slices. Layer the cauliflower on top of the potatoes.
Step 3: Add the layer of fresh leaf spinach.
Step 4: Repeat with a layer of potatoes, and a layer of cauliflower for a total of 5 layers.
Step 5: Prepare the Vegan Alfredo Sauce: Sauté onions in vegetable stock until soft. Bring water to a boil in a small pot. Add the cashews and simmer for 10 minutes. Drain the cashews from the water.
Step 6: Combine almond milk, sauteed onions, boiled cashews, garlic, nutritional yeast, lemon juice, salt, and pepper in a blender. Blend until smooth, about 45 seconds to 1 minute. Pour sauce over the vegetables.
Step 8: Cover with aluminum foils and bake for 40-45 minutes. Remove foil and broil for 2 minutes to brown the top. Serve while hot! Enjoy!
❓ FAQs
Potatoes are a good source of minerals such as potassium and fiber, vitamin C, and B6. While many think of them as just carbs, in moderation they can be quite beneficial for your health.
Absolutely! If you’d like to add more vegetables to this casserole, try carrots, mushrooms, zucchini, or yellow squash.
Yes, you can. I recommend prepping the ingredients ahead of time and then waiting until you’re ready to cook it to assemble it so nothing gets soggy.

Laura Plant Based Private Chef
Fantastic dish. Before making this for a gal I chef for, I had to make it for my husband & myself to make sure it’s a winner. It is! I brought some to my dad & we gobbled up the rest so today, while I make it for my client, I’m making us another batch too. I always do half white beans with all cashew based sauces to cut down on fat & it really doesn’t take away any flavor or consistency. And I layered in yellow onion too. Otherwise I did recipe as is. I think it’d be excellent also w/ mushrooms layered in. Great dish! My new client says she loves potato casseroles & I just happened to find this one. She’s going to LOVE it.
Janice Stanton
We are really getting into Plant Based eating. I am reading everything I can get my hands on. I love your website and all of your printable recipes. I need to get a few more things like cashews and the yeast. I am definitely going to try this potato recipes. I am make one of you pasta recipes tonight.
Thank you
Alison Corey
I hope you enjoyed the pasta dish. The potato casserole is very creamy and good too!
MaTaylie M Beganovic
I plan on making this tomorrow, and have everything on hand except Walnuts. Can I sub out for pecans?
Alison Corey
Yes, you can certainly substitute pecans!
Daniela Barrientos
I don’t have any cashews, is there something else i could use to substitute for it?
Alison Corey
Hi Daniela,
Unfortunately, to make the sauce the cashews are a key ingredient. It is what makes the sauce thick and creamy. Using another type of nut will not result in the same texture. However, you could try using silken tofu instead. I haven’t made this recipe using that method, but I’ve seen it suggested by others.
Mary
Delicious and easy to make; my sister went plant based and I needed something for main course. This with relish was perfect-thanks!
Alison Corey
Hi Mary!
I’m so happy to hear that you and your family enjoyed this dish!
Danielle Lucido
I made this tonite for father’s day for my husband. It was yummy but I agree with prior comments that 45 minutes is not long enough at 350. I put it in for 55 and it still could have gone longer. My potatoes were sliced quite thin, too. I think next time I will cook at 400. Thanks for the recipe!
Alison Corey
Thank you for your suggestions! I made this recipe again this week to test out the times, and have made some adjustments to both the time and temperature.
Melanie
When I made it, I increased the temperature and baked it longer so that the potatoes on the bottom were soft. In the future, I will add a bit of sauce to every layer instead of just on top.
Delicious!
Alison Corey
Glad you enjoyed it!
Valerie Broman
Made this tonight. I wish I would have read the recipe through before I started as I didn’t realize the cashews needed an overnight soak. I did a quick simmer and the sauce turned out well. I had to cook for 1 hour as it wasn’t done when cooked for the time in the recipe. It was worth the wait. Very tasty. My son and husband also loved it.
Alison Corey
Hi Valerie! I’m so happy to hear your husband and your son enjoyed the casserole! You can make the cashew cream sauce two ways. If you have a high speed blender you can soak the cashews overnight or at least for a few hours, but if you don’t have time to soak the cashews you can use my short-cut method which is to grind the cashews in a coffee or spice grinder. It makes for a creamy consistency. I’m sorry to hear the timing didn’t quite workout. How long did you end up needing to cook it for in the oven?
