The 6 Ingredients used to make
loaded mashed cauliflower

When my mother made loaded mashed potatoes, she added French onion dip and cheddar cheese to her potatoes. For this cauliflower mash casserole I use French onion dip, cheddar cheese, cream cheese, chives, bacon and cauliflower. All those cheeses and bacon are what make this cauliflower casserole loaded!

Let’s make some keto comfort food!

You start by cooking the cauliflower in the microwave for about 10 – 15 minutes. You want the cauliflower to be fork tender. I have used this microwave steamer for years and years for things cooking vegetables like this.

Tip: It’s better to steam cauliflower rather than boil it to keep it from being too watery. The cream cheese also helps the thicken mashed cauliflower.

Once the cauliflower is cooked add it to a high speed blender like a Vitamix along with the onion dip and cream cheese. The onion dip give the cauliflower mash tons of flavor. 

Next you sprinkle the cheddar cheese on top and place the loaded cauliflower casserole in the oven.

 Bake it for about 10 minute until the cheese is nice and melty. Then take it out of the oven and sprinkle the bacon and chives on top.  

So like my mother’s twice baked mashed potato casserole, this is a twice baked mashed cauliflower casserole … but with bacon!!

Recipe Tips & NOtes

• Note that this dish took a whole head of cauliflower to make this batch. I could eat two helpings of this myself. If making this for a crowd you might want to double or triple this recipe.
• It’s better to steam rather than boil the cauliflower but you can use either method. Just make sure to drain all of the water out before putting it into the blender. This will keep the cauliflower from becoming too watery.
• The cream cheese will help to thicken the cauliflower mash. If you want you can add some of the cheese as well into the mash instead of the top.

I hope you try this loaded mashed cauliflower casserole and maybe even make it for a holiday side dish. It really is a great substitute for mashed potatoes. I think you and your guests will love it!
