Ingredients You Need

Before we dive into cooking, let’s make sure we have everything on hand. Here’s what you’ll need:

  • Cauliflower (approx 2 pounds): This humble veggie is the star of the show, standing in for traditional pasta.
  • Heavy cream: Adds that rich, creamy texture to our sauce.
  • Shredded cheese (mozzarella, cheddar, etc): The cheesier, the better! Mix and match to your heart’s content.
  • Garlic powder: For that aromatic kick.
  • Oregano (optional): Adds a subtle herbal note. Feel free to skip it if you’re not a fan.
  • Salt and ground black pepper
  • Xanthan gum: This low-carb thickening agent works its magic here.

Now that you’ve sorted your ingredients, let’s move on to the fun part – cooking up some keto mac n cheese!

How to Make It

Let’s break it down into simple steps:

  1. Cut and Steam: Cut the cauliflower into small, bite-sized pieces. Steam them in a pot until they’re tender but not mushy. Once done, strain them and set them aside to cool.
  2. Creamy Cheese Sauce: Warm the heavy cream over medium-low heat in a small saucepot. When it simmers, add in your shredded cheese, garlic powder, oregano (if using), salt, and ground black pepper. Stir until that cheese is melted and the sauce is uniformly creamy.
  3. Thicken It Up: Sprinkle the xanthan gum over the surface of the sauce. Stir it in well and let it sit for about five minutes. This little trick helps our sauce thicken up beautifully.
  4. Combine and Serve: Finally, pour the luscious cheese sauce over the steamed cauliflower. Give it a good mix to ensure every floret is coated in creamy goodness. Serve it up warm, and get ready to savor the keto-friendly comfort!

How to Store It

Now, if you somehow manage to resist gobbling up the entire batch in one go, here’s how to store your leftover Keto Mac and Cheese:

  • Refrigeration: Pop it in an airtight container and store it in the fridge for up to three to four days. Just be sure to reheat gently to maintain that creamy texture.
  • Freezing: You can also freeze this dish for longer storage. Place it in a freezer-safe container or resealable bags. Remove as much air as possible. It’ll stay good for about up to three months, so label and date clearly. Thaw and reheat when you’re ready to enjoy.

What to Serve with It

Keto cauliflower mac and cheese is delightful on its own, but you can take it to the next level, and make it a more satisfying meal, by pairing it with these tasty additions:

  • Shredded Chicken: Easy to batch cook ahead of time and keep on hand for quick prep meals.
  • Pot Roast: Make a classic comfort food dinner with a hearty pot roast.
  • Grilled Pork Chops: Savor the smoky flavor and juiciness of grilled pork chops. Great for summer cookouts.
  • Baked Salmon: Delight in the rich taste of baked salmon, or try salmon burgers for a twist.
  • Bacon Bits: Because everything’s better with bacon, right? Crumble some crispy bacon on top for a flavor explosion.
  • Keto Chicken Fried Steak: Double up on comfort with a low-carb dish straight out of the South.

Cauliflower keto mac and cheese is proof that you can have your comfort food and eat it too, even on a low-carb diet.

It’s easy to make, utterly delicious, and opens the door to endless customization.

So go ahead, whip up a batch, and savor the cheesy goodness – guilt-free!
