Ingredient notes

Cauliflower – a medium-size cauliflower will work great in this recipe. Remove the stem and cut it into big chunks before steaming it. You can also use pre-cut bagged cauliflower. I haven’t used frozen cauliflower with this recipe so I’m not sure if that would work.

Chicken broth – this gives the cauliflower another layer of flavor – it’s my favorite way to prepare this recipe. However, if you don’t have chicken broth then steaming the cauliflower in water will work fine. Vegetable broth can also be used.

Sour cream – I use full-fat sour cream in this recipe but you could use lite sour cream or plain Greek yogurt to reduce the amount of saturated fat.

Salted butter – This recipe only calls for 2 tablespoons of salted butter, which is all that’s needed for that creamy texture and rich flavor.

Sharp Cheddar Cheese – In my opinion, the BEST cheese to use on loaded potatoes is sharp cheddar cheese. It gives an amazing tangy sharp cheese flavor that you really can’t get with another cheese. So, when I was preparing this loaded cauliflower mash I decided to stick with sharp cheddar because I know it works. Of course, use whatever cheese you want.

Shredded Parmesan cheese – Adding in a little shredded parmesan cheese is a great way to easily include another layer of flavor. Grated Romano cheese will work too.

Cooked bacon – Can you even create a loaded cauliflower mash without bacon? I’m going to say no. I only used 4 cooked crumbled slices in this recipe and this gave the perfect amount of flavor without a lot of extra fat and calories.

Green onions or chives – This cauliflower loaded mashed potato recipe uses green onions because that’s what I had on hand. Chives also taste great in this recipe.

Anything that you’d put on your loaded baked potato will taste delicious stirred and baked into cauliflower mashed potatoes.

How to Make Loaded Cauliflower Mash

Step 1: Remove and discard the stem from the cauliflower and then break, or cut, the cauliflower into chunks. The pieces just need to be cut small enough to fit comfortably into the pot. So, it’s okay to keep in larger chunks if they fit. Set the cauliflower aside for a minute or so.

Pour the chicken broth into a 5 ½ quart pot and bring it to a boil. Reduce to a simmer and then add in the cauliflower. Cover and steam until tender but not soft. This takes around 10 minutes. You should be able to poke a fork through the cauliflower without it falling apart.

Step 2: Drain the cauliflower and place it into a bowl.

Step 3: Using a potato masher and mash the cauliflower until you get the desired texture. If you prefer a smooth creamy mash then use a hand mixer or food processor to process the cauliflower.Preheat the oven to 350 degrees.

Step 4: Mix the butter, sour cream, grated parmesan cheese, shredded cheddar cheese, cooked bacon, salt, and pepper into the mashed cauliflower. Save some of the bacon to sprinkle on top. Give it another taste for salt.

Step 5: Place the mixed ingredients into a 8 x8 casserole dish, sprayed with cooking spray.

Step 6: Bake for 20 -25 minutes until hot and bubbly on the sides.

Recipe FAQs

Steaming the cauliflower in chicken broth adds more flavor. – If you don’t have chicken broth available then using salted water will work. However, for the most flavor, I recommend using chicken broth or even vegetable broth.

Don’t overcook the cauliflower. The cauliflower should be tender but still a little firm. You should be able to stick a fork through it without the cauliflower falling apart. Overcooking the cauliflower will result in a mushy instead of a hearty texture.

Remember, for this recipe the cauliflower is being cooked twice.

Use a potato masher or hand mixer to get the consistency you want. If you prefer a chunkier “cheesy potato” consistency then use a potato masher to process the cauliflower. If you want a creamier mash then use a hand mixer to whip the cauliflower until smooth.

Shred your sharp cheddar cheese. I know this takes a little more work but it adds more flavor and melts extra creamy. Of course, pre-packaged shredded cheese will work but nothing beats shredding your own.
