When watching carbs, sometimes, you miss comfort foods like mashed potatoes. But, eating low carb should never leave you feeling deprived.
If you’re struggling with not eating potatoes, this healthy, loaded cauliflower dish can knock those cravings right out. The keto cauliflower casserole makes a great side dish where you would normally serve potatoes.
This tastes like twice-baked cauliflower, and it's full of filling ingredients.
Loaded cauliflower casserole is so good, and it’s full of flavor while still being low-carb and gluten-free. It tastes just like a loaded baked potato without having to worry about all the carbs that come with it.
Even fussy eaters and children have been known to enjoy it!
There are just a few simple ingredients in this cheesy cauliflower casserole. Here's a bit more information about what I used.
You can use either fresh cauliflower or frozen cauliflower. Either way, you will need to steam them to get them tender enough to mash.
If you are running short on time, just grab a bag of frozen steamed cauliflower from the store.
Either salted or unsalted butter will work perfectly in this recipe.
If you use salted butter, just make sure to cut back on how much salt you add to the recipe.
I used garlic powder instead of fresh garlic for my loaded cauliflower casserole. I love how it turned out!
You could also sprinkle in some onion powder or even a dash of cayenne pepper.
For the best flavor, use full-fat sour cream. It will add depth to this tasty casserole.
For the brightest taste, I suggest using fresh chives. These are optional, so you don't have to use them if you don't like their flavor.
Use sugar-free bacon! It's best if you use cooked bacon that is completely cooled down and chopped.
Feel free to use your favorite type of cheese here. I used a combination of Monterey Jack and cheddar cheese.
Please note: Check out the recipe card at the bottom for a full list of ingredients used to make this low-carb recipe.
- Make sure the cauliflower is fully cooked. It should be fork tender so that it mashes up really well.
- Use your favorite type of cheese. Any grated cheese can be used in place of Monterey and cheddar.
- If the mashed cauliflower is too thin, add some softened cream cheese. You can use this in place of sour cream or add it in addition to it.
