  • 1 pound Broccoli florets chopped into bite-sized pieces
  • 2 cups Chicken (grilled or rotisserie) chopped into bite-sized pieces
  • 4 tablespoons Butter
  • 3 tablespoons Almond flour
  • 1/2 medium Onion chopped
  • 2 cups Whole milk
  • 2 cups Cheddar cheese shredded
  • 2 large Eggs whisked
  • 1 teaspoon Creole seasoning
  • 1/2 teaspoon Sea salt
  • 1 teaspoon Pepper


  • Preheat oven to 375 degrees. Lightly butter a 8 x 8 casserole dish.
  • Chop the broccoli into bite sized pieces (include the tender part of stems). Microwave in a bowl with a splash of water for 4 minutes. Remove and drain - set aside.
  • Melt the butter in a saucepan over medium heat. Add the chopped onion and cook for 2 minutes until translucent. Add the almond flour and stir for 1 minute to form a roux and to cook the flour.
  • Slowly pour in the milk, whisking continuously until it thickens and just begins to simmer. Remove from the heat.
  • Let it cool for 2 minutes and then stir in the cheese, then the beaten eggs, and seasonings. Make sure that you stir after adding eggs to avoid scrambling.
  • Fold in the broccoli, and chicken, and pour into the casserole dish. Sprinkle a little creole seasoning on top. Bake uncovered for 30 minutes until browned and bubbly. 
  • Top with a handful of grated cheddar cheese and serve hot.


For the "old-timers" who remember this classic dish with rice - simply serve it over cauliflower rice!
