Cauliflower Rice in a Keto Casserole

Rather than using grain rice for the casserole, I swapped in frozen cauliflower rice and it worked perfect!

You can use fresh cauliflower rice if that’s what you have, but I honestly prefer frozen the most. I find that it has the least cauliflower flavor, and is much less “farty” smelling, if you know what I mean, ha!

Creamy Sauce + Other Ingredients

The cream sauce is made from a combination of bone broth, soaked cashews + nutritional yeast. It makes a delicious, thick and creamy sauce that is completely dairy free! If you’re ok with dairy, you can substitute heavy cream instead of cashews. See recipe notes for substitution recommendations.

The keto casserole also has chicken, onions, mushrooms, kale + garlic. Perfect for winter. It is topped with the most genius crunchy topping: pork rind panko! Just ground up pork rinds. It gives it a great crunch. Do no skip this!

Make Ahead Keto Casserole

You can fully assemble this casserole earlier in the week, and then cook it the day you’re going to have it for dinner. You can even freeze it! I would just wait to add the pork rind panko until you’re going to put it in the oven. This way the pork rind panko will stay crispy!

This recipe makes a ton! Enough for 8 servings. Perfect for meal prep and to have leftovers for lunches and dinners!

  • 3 6-ounce chicken breasts
  • 1 tablespoon olive oil
  • 1 onion, chopped
  • 8 ounces mushrooms, sliced
  • 1 teaspoon kosher salt
  • 1 teaspoon pepper
  • 3 cloves of garlic, grated or finely minced
  • 1 bunch of kale, stems removed, chopped (about 3 cups)
  • 3 cups chicken stock
  • 1 cup raw cashews, soaked overnight
  • 2 tablespoons nutritional yeast
  • 3 teaspoons salt
  • 3 12-ounce bags frozen cauliflower rice
  • 1/3 cup pork rind panko, optional


  • Preheat your oven to 425ºF. Line a rimmed baking sheet with parchment paper for easy cleanup. Set in the wire baking rack. Place the chicken breasts on the wire rack, season with salt and pepper. Roast for 25 minutes. Remove from the oven, and chop into bite size pieces.
  • Reduce your oven temperature to 350ºF.
  • While the chicken is roasting, heat your cast iron skillet over medium heat. Add the olive oil, onion and mushrooms. Season with 1 teaspoon salt + pepper. Sautee, stirring occasionally, until caramelized and golden brown. About 10 minutes.
  • Add in the garlic, and cook for 30 seconds until fragrant. Then add in the kale, and sautee until soft, about 5 minutes.
  • To make the sauce, in your high speed blender combine the chicken stock, soaked cashews, nutritional yeast and salt. Blend on high for 60 seconds until completely smooth.
  • When the kale is soft, stir in the frozen cauliflower rice and chopped chicken. Stir until completely combined. The cauliflower rice will still be frozen. The oven will do all the cooking of it!
  • Pour the sauce all over the top of the casserole. Use a spatula to gently nudge it to be completely absorbed.
  • Top the casserole with crushed pork rind panko.
  • Bake in the 350ºF oven for 20-25 minutes, until bubbling and golden brown.
  • Remove from the oven and let rest for 5-10 minutes. Serve warm.
  • Leftovers will keep in an airtight container refrigerated for at least 5 days, or frozen for at least 6 months.
  • As always, lots of tips, FAQs and substitution info in the Recipe Notes!


Chicken: I get my organic, hormone + antibiotic free chicken from ButcherBox, which I highly recommend! This is also a great use for rotisserie or leftover chicken.
Casserole Dish: If you don't have a cast iron skillet, you can pour it all into a 9x13 or 6 quart baking dish.
Frozen Cauli Rice: You can pour the cauliflower rice in straight from frozen! No need to thaw.
Using Dairy: If you're ok with dairy, you can skip the cashews and instead use 2 cups bone broth and 1 cup heavy cream. This would make it even lower in carbs! You can also add in some grated parmesan. Yum!
Quick Soak for Cashews: To do a quick soak, cover your cashews in 3 cups boiling water for 1 hour.
