Ingredients Notes

Ingredients all laid out to make a low carb chicken cordon bleu casserole
  • Chicken: For this chicken cordon bleu casserole, I used boneless, skinless chicken breasts, but you could also use chicken thighs. To make this recipe even quicker, you can also use shredded rotisserie chicken. (more keto chicken recipes).

  • Ham Steak: I bought a large ham steak and cubed it up, but you can also use sliced deli ham, pancetta, or even bacon. (more keto ham recipes)

  • Cauliflower: What would a low carb casserole be without the addition of cauliflower? But seriously, adding the cauliflower and the mushrooms adds more heartiness to this casserole. (Try my Loaded Cauliflower Casserole Recipe)

  • Swiss Cheese: For this recipe, I use Swiss cheese because it is a classic component of cordon bleu, but you can honestly use any cheese you prefer. Some of my favorites for this recipe are mozzarella, sharp white cheddar, or smoked gouda.

  • Tarragon: Tarragon has a similar flavor to fennel or anise. It really adds something special to the sauce for this keto chicken cordon bleu casserole.

STEP 7: Drain the chicken stock from the pan. Leave the cauliflower in the hot pan, but remove the pan from the heat. This will allow some of the excess moisture to continue to evaporate from the cauliflower.  Once nearly all of the liquid is evaporated, fork mash the cauliflower.

STEP 8: In a 3 quart casserole dish, combine the mashed cauliflower, meat mixture and sauce.
