Loaded Cauliflower Mash Casserole



This complete meal includes creamy mashed cauliflower topped with chicken, cheese, bacon, broccoli and scallions for a delicious and filling meal!
Now that I have a delicious and easy mashed cauliflower recipe, I am having so much fun thinking of meals I can make with it! And fun this meal was. What started as something that I threw together to use some of my leftovers turned into a really tasty and easy meal that I can’t wait to make again! And with chicken, cheese, bacon and broccoli along with all of the cauliflower, this dish is a complete meal in its own right. Thankfully it’s gluten-free, grain-free, low-carb, low-glycemic, keto diet-friendly and packed full of nutritious veggies, because it is so good!
Here are a few tips to make this meal as inexpensive and easy as possible:
  • I buy frozen organic cauliflower florets and frozen organic broccoli florets at Costco. They have the best price, unless you are able to grown your own or use fresh cauliflower and broccoli. Each contains premeasured bags that can be steamed quickly and easily in a steaming basket or microwave.
  • If you don’t have leftover chicken to use, both Costco and Natural Grocers have organic boneless, skinless chicken thighs for a reasonable price. Put 3-4 chicken thighs (about 1 pound) in a baking dish and roast at 400 for 30 minutes, then tear into bite size pieces to go on top of the cauliflower mash.
  • I use my trusty Ninja Master Prep to make the cauliflower mash. It’s only $35 for the blender and food processor attachments, and it does a good job of making the cauliflower mash nice and creamy!


Cauliflower mash topped with chicken, cheese, bacon and broccoli come together to make a delicious meal that is grain-free, gluten-free, low-carb and ketogenic!


I hope you enjoy this gluten-free, low-carb, keto diet-friendly meal that’s loaded with vitamins, minerals and antioxidants from the cauliflower and broccoli! Click the links for each vegetable to learn more about its health benefits and keep scrolling for the recipe!

Mashed Cauliflower Ingredients

  • 2 lb frozen cauliflower florets or 1 medium head cauliflower, chopped (about 4 cups)

  • 1/2 tsp salt

  • 3 thick slices bacon, cooked and chopped
  • 1 cup shredded cheese
  • 2 green onions, slivered

Mashed Cauliflower Instructions

  1. Steam cauliflower for 8 minutes, either in a steaming basket over boiling water on the stove, or in its bag in the microwave (cut a hole in the bottom and drain excess water after cooking if using this method). Place steamed cauliflower in blender with butter and salt. Let sit for a few minutes while the butter melts and softens.

  2. Add the mayo and blend until smooth, about 1-2 minutes.
