When tangy BBQ chicken shows up in our weekly meal plan, my husband’s eyes always light up with excitement. But this time — when I told him it was coming in casserole form, that it involved tender riced cauliflower, and was Paleo — his eyes got squinty in the way that only happens when he’s skeptical. I, however, knew it would be a hit with him. So when he asked if there was enough for seconds after taking his first bite, I wasn’t surprised.

What This Tastes Like

If you like chicken, BBQ sauce, and cauliflower, this casserole will be right up your alley. Because we’re keeping this version Paleo-friendly, it lacks the usual suspects typically mixed into casseroles, like cheese, bread, pasta, and grains. Instead, a few beaten eggs work as the glue that hold this mixture of juicy shredded chicken, tender cauliflower rice, and sauce together, and prevent it from drying out.

Make Your Own BBQ Sauce or Start with Store-Bought

The chicken breast and riced cauliflower may be the main ingredients of this weeknight casserole, but I think we can all agree that it’s the BBQ sauce that really makes it sing. This recipe starts off with instructions for a quick homemade Paleo-friendly sauce. Don’t be put off by the ingredient list — it appears a little lengthy, but is really quite easy to pull together with pantry basics. But don’t fret if making your own sauce doesn’t fit with your schedule! A store-bought sauce will work just fine, whether you choose a version that’s Paleo-friendly or not.

Nutritional Info

Ingredients

For the sauce:

  • 1

    (6-ounce) can tomato paste

  • 1 cup

    low-sodium chicken broth

  • 1/2 cup

    apple cider vinegar

  • 2 tablespoons

    honey

  • 2 tablespoons

    coconut aminos

  • 2

    cloves garlic, minced

  • 1 teaspoon

    onion powder

  • 1 teaspoon

    smoked paprika

  • 1/2 teaspoon

    chili powder

  • 1/2 teaspoon

    kosher salt

  • 1/4 teaspoon

    freshly ground black pepper

  • 1/8 teaspoon

    cayenne pepper

For the casserole:

  • Olive oil

  • 1 pound

    boneless, skinless chicken breasts

  • 16 ounces

    riced cauliflower, thawed if frozen

  • 4

    large eggs, beaten

  • 1/2

    medium red onion, diced

  • 1/2 teaspoon

    kosher salt

  • 1/4 teaspoon

    freshly ground black pepper

  • 2

    medium scallions, green parts only, thinly sliced

Instructions

  1. Arrange a rack in the middle of the oven and heat to 400°F. Coat a 9x13-inch or 2-quart baking dish with oil; set aside.

  2. Make the sauce: Whisk all the ingredients together in a medium bowl until well-combined; set aside.

  3. Make the casserole: Arrange the chicken in a single layer in a large saucepan. Add enough cold water to cover the chicken breasts by 1 inch. Bring to a boil over medium-high heat. Reduce the heat to low, cover, and simmer until the chicken is cooked through and an instant-read thermometer in the thickest part registers 165°F, 8 to 12 minutes depending on the thickness of the chicken breasts.

  4. Transfer the chicken to a cutting board or large plate and use 2 forks to shred the meat while still warm.

  5. Place the cauliflower and eggs in a large bowl and stir until well-combined. Stir in the shredded chicken, onion, 1 1/2 cups of the sauce, salt, and pepper. Transfer to the prepared baking dish and press into an even layer. Pour 1/2 cup of the sauce over in an even layer.

  6. Bake until the casserole is set and lightly browned around the edges, 40 to 45 minutes. Let sit for 5 minutes before cutting and serve. Drizzle with the remaining BBQ sauce, top with scallions, and serve.

Recipe Notes

Make ahead: The sauce can be made up to 2 days in advance and stored in an airtight container in the refrigerator. The chicken can be poached and shredded up to 1 day in advance and stored in a separate airtight container in the refrigerator.

Precooked chicken: To skip cooking the chicken, use 2 1/2 cups shredded rotisserie chicken instead.

Store-bought sauce: Instead of making your own sauce, use 2 1/2 cups of store-bought sauce.

Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
