Equipment

  • blender
  • box grater
  • medium-sized casserole dish

Ingredients

For Cashew Sauce

  • 1-1/2 cups raw cashews
  • 1-1/2 cups water
  • 3 garlic cloves, chopped
  • 1/2 teaspoon turmeric powder
  • 1/2 teaspoon chili powder
  • 1/4 teaspoon cayenne pepper
  • 1/4 teaspoon Himalayan sea salt
  • 1/4 teaspoon freshly ground black pepper

For Sweet Potato Casserole

  • 1 large sweet potato, about 1 pound, grated (it will measure about 5 cups when grated)
  • 1 cup grated daikon radish
  • 1 head broccoli, cut into bite-sized pieces, about 4 cups
  • 2 cups fresh or frozen sweet peas
  • 4 ounces plant-based cheese (such as Miyoko's brand Mozzarella), grated
  • 1/4 cup bread or cracker crumbs (see notes)
  • Sweet, hot, or smoked paprika for sprinkling on top of casserole

Instructions

  • Preheat the oven to 400ºF.
  • Put all of the cashew sauce ingredients into a high-speed blender; set aside while you prepare the rest of the casserole ingredients (if you aren't using a high-speed blender, first pre-soak or pre-cook the cashews).
  • Put the grated sweet potato, grated daikon radish, chopped broccoli, peas, and grated cheese into a medium-sized casserole dish (the one I use holds 2 quarts).
  • Blend the sauce until creamy, then pour it over the vegetable mixture. Stir well until everything is combined and covered with the cashew sauce.
  • Sprinkle with the bread or cracker crumbs, then sprinkle with paprika.
  • Cover the casserole dish. If your casserole dish doesn't come with a cover, cut a piece of parchment to fit inside the casserole dish. The idea is to prevent the casserole from drying out.
    Bake for at least 40 minutes, or until very bubbly.

Notes

How to make gluten-free cracker crumbs
Consider making gluten-free cracker crumbs from Simple Mills brand almond crackers. Simply pulse them in your food processor or bullet blender until the crackers are evenly chopped into crumbs (don’t overprocess). For reference, about 1/4 box of Simple Mills almond crackers (about 17 crackers) makes 1/4 cup of bread crumbs.
