Healthy Hash Brown Casserole Recipe (1)

I wish I had a cute story behind this not-so-cute dish, but the truth is that I saw a hash brown casserole recipe online and wanted to fat-free veganize it. So I did.

I threw out all the butter, the cheese, the sour cream, the cream of chicken-parts soup, as well as the corn flakes on top, and what I had left was a package of hash brown potatoes–and the need for a really good sauce. So I turned to my favorite cheesy sauce, which can magically transform even the most mundane ingredients into instant comfort food.

As you know, I can’t resist the impulse to turn side dishes into one-pot meals, so I chopped up some kale and added a can of chickpeas, which resulted in one of the least attractive casseroles I’ve ever seen (and casseroles aren’t generally known for their beauty). But it tasted rich and comforting, with less than half of the fat of the original (even though my servings are much larger) and none of the cholesterol. And as an added bonus, it’s gluten-free!

Besides being a great main dish, consider this the perfect choice for your next brunch or hearty breakfast. Leftovers keep well—just reheat gently in the oven or taster oven.

Kale and chickpeas give this comfort food a nutritional boost and turn it from a side to a main dish, but if you want to make the more traditional side dish, see the notes at the end of the recipe.

  • 1 1/4 cups water
  • 1 cup plain sugar-free non-dairy milk
  • 3/4 cup nutritional yeast
  • 1/4 cup raw cashews or 2 tablespoons tahini optional
  • 3 tablespoons potato starch or cornstarch
  • 1 1/2 tablespoons lemon juice
  • 1 - 1 1/2 teaspoons salt omit for low-sodium diets
  • 1 teaspoon dry mustard
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon turmeric
  • 1/8 - 1/4 teaspoon cayenne pepper optional
  • black pepper to taste


  • 1 large onion chopped
  • 3-4 cloves garlic minced
  • 12 ounces kale stems removed and leaves chopped
  • 16 ounces frozen Southern-style hash brown potatoes thawed (see notes below)
  • 1 15- ounce can chickpeas rinsed and drained



To make a more traditional style casserole, leave out the kale and chickpeas and use a 32-ounce package of hash browns instead.

Be sure to buy diced hash browns with no oil added. They should contain about 70 calories and no fat per serving. If they aren't available, peel and cut regular potatoes into 1/2-inch cubes.

    I don’t have nutritional yeast… can I leave that out or will it be a disaster?
    I searched substitutes but most say cheese and I’m tying to keep it cheese-free.

      It’ll lose a lot of flavor without nutritional yeast. You might be able to add seasonings to it, but it won’t taste the same. Some recipes you can omit nutritional yeast from without problems, but this one really needs it.

    I’ve been making this recipe regularly for a year or so now. I just wanted to let you know that this has become a staple for our family! I usually sub spinach for the kale (my kid is more likely to eat it that way) and we just love it 😁❤️

    Will this work with peeled and diced potatoes?


    • Susan Voisin

      Yes, just make sure they’re evenly diced.

    This turned out amazing!! I had to make a few tweaks because I am running low on groceries and it still came out amazing. I used shredded oil free hash browns. I only has half a cup of oat milk in the fridge so I used that and upped the water and upped the cashews a bit to make up for less milk. I ran out os smoked paprika the other day so i used regular paprika and a little bit of chipotle powder to give it a smokey ness. It was outstanding. I can’t want to try it with cubed potatoes.

    Can I prepare this in the evening, refrigerate overnight, and bake it in the morning?

      I haven’t tried that, but I don’t see any reason why it wouldn’t work.
