I was very excited when Better Homes & Gardens asked me to share a recipe with you. I’ve only been blogging for a little more than a year, and this is my first guest post ever. I still can’t believe it’s on Delish Dish! How cool is that? 

I was able to choose any recipe on the BHG site to adapt. With Thanksgiving a week away, I decided to take a classic side dish and make it low carb and Trim Healthy Mama friendly. I chose Cream Cheese Mashers with Kale Pesto knowing cauliflower would work to replace the potatoes.

We are traveling for Thanksgiving, but I’m hoping my sister-in-law lets me help with Thanksgiving dinner. Besides the turkey, I’m hoping for a few substantial low carb, THM S options.

My Keto Mashed Cauliflower with Cream Cheese and Asiago is definite. Also in the options are a healthy green bean casserole, roasted broccoli, butternut squash, and my Braided Garlic Breadsticks. I might whip up some Mini Pumpkin Cheesecakes to finish off the meal.

I love cooking so much that I end up there no matter where we are for holidays. I elbow my relatives out of the way and plant myself before the stove — half kidding. But at the very least I come armed with appetizers, sides, and pies from my own kitchen.

How to Make Keto Mashed Cauliflower

Step One: Steam the cauliflower and roast the garlic. I cheat a bit on this step and use steamable bags of frozen cauliflower florets. Just toss them in the microwave and they are ready in minutes. If you want to use fresh cauliflower simply steam until it is fork-tender.

Step Two: Puree the cauliflower with the seasonings in a food processor. This is a large batch recipe so this needs to be done in two batches.

Step Three: Layer the cauliflower puree with the cheese. Pop into the oven and bake until hot, bubbly, and golden.

What To Serve With Mashed Cauliflower

• Sous Vide Pork Tenderloin
• Ground Turkey Meatloaf

Variations

I used super simple ingredients for my mashed cauliflower. But, because of the versatility, you can add in other ingredients that will add even more flavor and depth to this creamy and magical keto side dish. 

• Green Onions - Finely slice and mix in before layering.
• Diced Bacon or Pancetta - Add along with the shredded cheese.
• Chives - Mix into the puree.
• Rosemary or Parsley - Finely chop and mix into the pureed cauliflower.
• Parmesan Cheese - Add along with the shredded cheese.
• Cheddar Cheese - Swap cheddar in for the asiago.

Common Questions

Can I Make Mashed Cauliflower Ahead Of Time 

Absolutely! I had made this the day ahead of when I wanted it, and then just reheated in the microwave, or cover with aluminum foil and bake in the oven! Just heat until it is warmed all the way through, and then serve. 

It keeps the flavor from day one, so you don't feel it lacks in flavor at all. Keto Mashed Cauliflower reheats very well. 

How To Make A Thick and Creamy Cauliflower Mash

I have been making this cauliflower mash for a while now, and I have learned that if you use more florets instead of stems, you will get a creamier texture. I also only use cream cheese and butter and do not add any type of milk or cream.

Can I Roast My Cauliflower Instead of Steaming It 

Yes, you are welcome to use roasted cauliflower if you prefer the flavors to roasted. Steaming or microwaving will give you the softest texture, which leads to a creamier texture. But roasting your cauliflower will give your mashed cauliflower more depth in flavor. 

How Do You Roast Garlic In Oven

To roast your garlic, you will place your garlic slice head down so that the cloves are exposed. Then drizzle over olive oil and season with salt and pepper. Wrap your garlic in aluminum foil and place it on a baking sheet. Bake for about 30 minutes at 400 degrees. You want to have the garlic soft enough that if you squeeze the bulbs come out easily. 

You can make your garlic ahead of time and store it in the fridge. Then warm in the microwave when ready to use it.

How Do You Cook Cauliflower To Taste Like Mashed Potatoes

My keto cauliflower mash is going to curb those starchy potato cravings. Take your steamed cauliflower and place it in a food processor. Then add in all other ingredients and blend until nice and creamy. All of the contents might not fit in your processor, so work in batches. Top with your Asiago cheese, and then bake in the oven at 400 degrees, for around 30 minutes. Once it is bubbly and hot, remove and serve.

This recipe right here adds heavy cream, cheese, roasted garlic, and more to add flavor and mimic mashed potatoes. I can't rave enough over this easy and savory dish. 

Can You Make This In A Blender 

Absolutely. If you don't have a food processor, you are welcome to reach for your blender. Just blend your cauliflower mash to a creamy consistency in small batches, scraping the sides as needed. 

Can You Freeze Mashed Cauliflower

Yes, you can freeze any leftovers you might have. Place them in a freezer-friendly container and then store them in the freezer for up to three months. Thaw in the fridge the night before you want to serve it.

Then warm in the microwave or heat in the oven. If you heat it up in the oven, wrap it in aluminum foil, and heat it until it is cooked through. 

Best Way to Store Leftovers

I place any leftovers we have in a container and toss them in the refrigerator for 3-4 days. Just heat in the microwave or oven when you are ready to eat more of it.

Ingredients

• ▢ 40 oz of frozen cauliflower microwaved or steamed until warm
• ▢ 1 head of roasted garlic ***
• ▢ 2 teaspoon salt
• ▢ ½ cup heavy cream OPTIONAL
• ▢ ¾ cup unsalted butter
• ▢ 12 ounces cream cheese softened
• ▢ 1 cup shredded asiago cheese

US Customary - Metric

Cook ModePrevent your screen from going dark

Instructions

• Put half of each of the first six ingredients in a food processor (the entire amount will not fit in a standard food processor). Process until smooth. Spoon into the baking dish. Top with half the asiago cheese. Repeat.
• Bake at 400 for 30 minutes or until golden, bubbly, and hot.

Notes

To Make Roasted Garlic: slice the head down the middle exposing the cloves, drizzle with olive oil, season with salt and pepper, wrap in foil and bake for 30 minutes at 400. The cloves will soften enough to squeeze out of the bulb. The best part is this reheats well. Feel free to bake it the day before and then just microwave to reheat.

Heavy Cream: when using frozen cauliflower it is watery enough that cream isn't needed. The cream is optional and I tend to only use it when I use fresh cauliflower.
