Ingredients

Scale

Protein and Vegetables

  • 1 lb. shredded chicken breast
  • 6 oz. cooked and chopped bacon (about 1/2 package)
  • 3 cups frozen hash browns or shredded potatoes
  • 2 crowns broccoli florets (about 2 heaping cups)
  • 1 diced white onion (1.5 cups)
  • 1 cup sliced mushrooms

Sauce

  • 1 (13.5 oz) can coconut cream
  • 1/2 cup chicken broth
  • 1/2 cup almond milk
  • 2 tbsp ghee
  • 1 tbsp minced garlic
  • 3.5 tbsp Primal Kitchen Organic Dijon Mustard
  • 2 tsp dried thyme
  • 2 tsp parsley flakes
  • 2 tsp dried rosemary
  • 1 tsp salt
  • 1/2 tsp black pepper
  • 1.5 tbsp arrowroot flour dissolved in 2 tbsp water

Instructions

  1. Preheat Oven: Preheat your oven to 400°F to prepare for baking the casserole.
  2. Combine Ingredients: In a large casserole dish, add shredded chicken, chopped cooked bacon, frozen hash browns, broccoli florets, diced onion, and sliced mushrooms. Spread evenly.
  3. Make Sauce: Heat a large saucepan over medium-high heat and add ghee and minced garlic. Stir as the ghee melts and garlic sautés until fragrant, about 1-2 minutes.
  4. Add Sauce Ingredients: Pour in the canned coconut cream, chicken broth, almond milk, Dijon mustard, and dried herbs (thyme, parsley, rosemary), along with salt and pepper. Stir to combine and bring the sauce to a slow simmer.
  5. Thicken Sauce: Once simmering, add the dissolved arrowroot flour mixture to the sauce and immediately stir continuously. The sauce will thicken quickly and become a thick bubbling mixture.
  6. Combine Sauce and Casserole: Pour the thickened sauce over the ingredients in the casserole dish. Stir thoroughly to coat all meat and vegetables well, then spread the mixture into an even layer.
  7. Bake: Place the casserole dish in the preheated oven and bake for 1 hour, or until the top turns golden brown and bubbling.

Notes

  • If you don’t have cooked bacon, bake raw bacon on a sheet pan at 400°F for 12 minutes while preparing other ingredients.
  • If chicken breast is not cooked, a rotisserie chicken can be shredded, or chicken breasts can be poached in water on the stovetop for a quick prep.
  • Omit ghee for those with lactose allergy as this recipe is otherwise dairy-free.
  • If using freshly shredded potatoes instead of frozen, reduce baking time by about 15 minutes or until the top is golden brown, to prevent overcooking.
