Loaded Cauliflower Casserole

Loaded cauliflower casserole is one of my favorite side dishes and it’s a hit with my whole family! I pack in a bunch of bacon and cheddar to keep this low carb side dish recipe super creamy and flavorful. 

Things I’ve been craving lately: loaded french fries. Ugh.

There is a restaurant nearby that serves the best dang fries that are topped with cheddar, bacon, sour cream, and green onions. I used to eat them way too often.

I’ve given up the french fries for cauliflower and no, it’s definitely not the same, but my pants fit better and cauliflower is delicious.

I’ve even been working on a loaded radish recipe for you guys, which probably sounds weird but trust me – it’s going to be good. Still tweaking a few things in hopes of getting the radishes to cook up a bit crunchier.

Anyway, I’m all about cauliflower casserole recipes.  Cauliflower just makes a great base for pretty much everything, you know?

This cauliflower casserole with bacon and cream cheese is going to rock your world.

How to make this loaded cauliflower bake:

Start with a head of cauliflower, chopped up into florets.

I pop my cauliflower into a large microwave safe bowl, add a tablespoon of water, and cover with plastic wrap. Then I just microwave for about 4 minutes. You could also steam your cauliflower on the stove, if you prefer.

Once the cauliflower is nice and soft, grab a potato masher and go to town.

Once your cauliflower is mashed, stir in the good stuff – sour cream, cream cheese, and cheddar. This is going to be so creamy and amazing.

You’ll also stir in some bacon, green onions, garlic powder, salt, and pepper.

This just goes in the oven for about 20 minutes and you’re ready to serve!

Special Tools Needed for this loaded cauliflower casserole:

Potato masher: This makes mashing your cauliflower a breeze! This one from Amazon (affiliate link) has great reviews.

Baking dish: A 9×9 square dish or any shaped 2 quart dish will be perfect for this recipe. I just ordered this one (affiliate link) because it’s pretty and I have a thang for pretty dishes. 😉

  1. I just made this and it’s delicious! I asked my non- keto husband to try my potatoes, and he took a bite. He first said, this is cauliflower….boy is this delicious!
    Made two slight changes in cooking. First I steamed the cauliflower because it’s a healthier way to prepare ( even though it does take longer), and believe it or not I don’t have a masher, so I used my food processor. This is a winner!

    1. Karly Campbell

      Yep, should work fine. We just prefer the flavor of fresh cauliflower over frozen.

  2. I’m a diabetic and love to find recipes like this since I can’t have any carbs. Love it. Thank you.

    1. Karly Campbell

      It’d be one really big head of cauliflower or a little more on an average sized head.

  3. Cathy Peters

    I added a 1/2 packet of ranch dressing instead of garlic powder, so yummy!!
    Will try with broccoli as well

  4. Celeste de la Cruz

    made it, turned out great, was delicious. Only thing is it took twice that time and a lot more water in the microwave heating the cauliflower until it was tender enough to mash. It still didn’t mash that well, but it was fine by the time all the stirring, etc. got finished with. Will definitely be making this again, Thank you!!!

      Hi Jackie! I think you likely could, but keep in mind that cooked cauliflower often gets a bit stinky as it sits. 🙂

  5. Joan Thompson

    Absolutely delicious! It tastes like twice baked potatoes. My husband is new to keto, hates veggies but asked me to make this again. A huge victory

    1. Karly Campbell

      I don’t really freeze food myself, but I imagine it would freeze perfectly. I’d reheat in the microwave, covered for the first few minutes and then uncovered the last few minutes until hot…that’s solely based on the frozen packages of mashed cauliflower I’ve purchased though. Haha! 🙂

  6. Mary M Wilshire

    This is absolutely fantastic – and easy. It’s helping me come to terms with diabetes and the eternal carb count!

  7. OMG these look delicious! I’m a cauliflower addict too! It really is just so good and versatile. I may totally be making these in the next couples of weeks.
