Keto Cauliflower Mac and Cheese Recipe

This Keto Cauliflower Mac and Cheese will fix all your pasta cravings in less than 30 minutes!

Soft, tender steamed cauliflower bits coated with a cheesy mac and cheese sauce and only 5 grams of net carbs per serving! It’s comfort food at its best!

Optional Add-Ons

This recipe is delicious like this, but you can make it even more perfect with:

• Grilled Chicken: it won’t affect the calories or net carbs much and brings great taste.
• Bacon: for an extra boost of protein

Cut And Steam Cauliflower

First, place the cauliflower head on a chopping board and trim the outside leaves.

Next, cut the cauliflower head into small florets, bite-size of about 1 1/2 inches each.

Finally, place the florets into a steamer basket over a large saucepan of boiled water. Steam the florets for about 8 minutes.

You can also place the florets into a large mixing bowl and microwave for 6-8minutes until softer, not mushy.

Set aside the cooked cauliflower for a few minutes or until they have steamed out.

Alternatively, you can also grill the cauliflower in the oven by placing the florets sprinkled with cayenne pepper and olive oil on a baking sheet covered with parchment paper and cooking it for 10 minutes at 350°F (180°C).

Keto Mac and Cheese Sauce

Meanwhile, in a saucepan or pot, melt butter, then add almond milk, and bring to a light boil.

Then, whisk in softened cream cheese, Dijon mustard, garlic powder, paprika, salt, and pepper.

When the mixture is smooth, stir in 1 cup of each variety of shredded cheese. Keep cooking until the sauce is creamy and the cheese is melted.

Finally, stir the cooked cauliflower florets into the sauce and keep cooking for a few minutes until the cauliflower is well coated and flavored by the sauce.

Casserole Option

To turn this Keto Mac and Cheese Cauliflower recipe into a casserole, place the cheesy cauliflower florets onto a large 9×13-inch baking dish.

Sprinkle extra 1 cup cheese on top of the casserole with 1/2 cup bacon bits and bake it in the oven at 350°F (180°C) for 10 to 15 minutes or until the cheese is melted and grilled.

Serve immediately with fresh chopped herbs and keto rice on the side.

Cheese Options

I believe that the sort of cheese you use in a mac and cheese recipe is the key to making it flavorsome. Therefore, I listed below all my favorite cheese combinations for you to try.

• Munster cheese and sharp cheddar
• Shredded parmesan cheese and jack pepper cheese
• Emmental and sharp cheddar

Storage Instructions

This keto cauliflower mac and cheese recipe freezes very well in a freezable container.

Thaw it in the fridge the day before and rewarm in a small saucepan or the microwave until hot.

You can also store leftovers in the fridge for up to 3 days.

Instructions

• Trim the cauliflower stems, remove the leaves, then break into small bite-size florets about 1 1/2 inches wide.
• Place the florets into a steamer basket and steam for 8 minutes until fork tender.
• Cool down on a colander for few minutes until completely steamed out, then transfer to a large baking dish and spread into an even single layer.
• Meanwhile, prepare the mac and cheese sauce.
• In a large saucepan – large enough to fit the cauliflower florets – add the butter and almond milk and bring to a light boil, then whisk in cubes of softened cream cheese, Dijon mustard, garlic powder, paprika, salt, and pepper.
• When the mixture is smooth, stir in shredded cheddar and shredded gruyere.
• Stir over low heat for 1 or 2 minutes or until the cheese just has melted and a creamy sauce forms. If too thick or stringy, add more almond milk at room temperature until it reaches your liking.
• Stir the cooked cauliflower florets into the sauce and keep cooking for 1-3 minutes until hot.
• For a casserole, transfer into a 9×13-inch baking dish, sprinkle extra shredded cheese on top, and bake at 180°C (350°F) for 15 minutes or until cheese is broiled on top.
