About this Recipe

Guys, I was honestly shocked by the texture and flavor in this parmesan mashed cauliflower gratin recipe. It’s creamy, fluffy and delicious. Exactly how you would expect traditional mashed potatoes to be. Except this side dish recipe is a much lighter than traditional mashed potatoes.

What added so much flavor to the cauliflower was boiling the cauliflower in a combination of water and Smart Chicken’s garlic rosemary bone broth. You’ll want to boil the cauliflower until it is fork tender. Drain the liquid, and add the warm cauliflower to the food processor along with the butter, cheese and spices. Buzz until it is well combined. Then, add the cauliflower to a prepared cast iron skillet, and top it with freshly grated cheese and the panko breadcrumb mixture. Bake until golden brown and crispy. The breadcrumbs and cheese create a layer of crispy goodness that is hard to resist. Seriously, I had a hard time not licking the cast iron pan clean.

Parmesan Cauliflower Mash Gratin

To make this parmesan mashed cauliflower recipe completely keto, simply skip the panko breadcrumbs. Instead, you can combine the grated parmesan and Romano cheeses together and use that as is.

As far as protein goes, you can serve this cauliflower mash with just about anything. Some ideas would be grilled salmon, roasted chicken, or crispy tofu for a vegetarian twist. You can also try my blackened citrus salmon. The citrus would go really well with this mash too.

No matter what you serve this cauliflower mash with, it will taste great. It’s so good that I’m considering using this at Thanksgiving this year versus my traditional mashed potatoes. Although Dan may have something to say about that. Haha!
