Cauliflower Mac and Cheese Recipe

Low-carb creamy cauliflower mac and cheese is one of my favourite party recipes. While the texture isn't perfect, the flavour is like mac and cheese! Bacon and caramelised onions enhance this delicious recipe!


– 1 large (2.5-pound) head cauliflower chopped into small chunk – 6 strips thick-cut bacon – 1 medium-sized yellow onion finely chopped – 3 large cloves garlic minced – 2 Tbsp butter – 2 Tbsp all-purpose flour* – 1 to 1.5 cups half & half – 2 to 3 cups cheese grated** – Sea salt and black pepper to taste


Make macaroni-sized cauliflower. Smallen cauliflower for pasta. A large pot of water should boil. Thick Dutch oven bottoms. A single pot is best for this recipe. 

Step 1

Put chopped cauliflower in boiling water. Reboil 8–10 minutes to tenderise florets. Save cauliflower colander.

Step 2

Reheat pot medium-high. Flip the bacon strips every two minutes on the hot surface until crispy. Place bacon on plate or cutting board to cool. Leave bacon fat in pot to sauté onion.

Step 3

Add chopped onion to bacon fat pot and lower heat to medium. Sea salt the onion heavily. Soften and caramelise the onion for 20 minutes, stirring occasionally. 

Step 4

Here, caramelised onion flavour and texture deepen and soften. If creamy mac and cheese is okay, sauté onion al dente for 5 minutes.

Step 5

After the onion is soft and golden brown, add minced garlic and cook for 3 minutes until fragrant. Flour dissolves. Half-and-half simmer until thickened. Avoid boiling milk by heating on medium.

Step 6

A creamy sauce is made by melting grated cheese. Add cooked cauliflower to creamy cheese sauce. Season homemade mac and cheese with sea salt and pepper. 

Step 7

Chopped bacon and chives or broil mac and cheese make a golden brown casserole topping.

Step 8

Optional: Place one tray on the second or third rack from the top of the oven on high broil. Spray a large 13" x 9" casserole dish with cooking spray. Spread cauliflower cheesy mixture in baking dish. I add 1–2 cups cheese to cauliflower.

Step 9

3–5 minutes, broil cheese until melted and golden brown. Chopped crispy bacon and chives go with baked mac and cheese. Serving baked cauliflower mac and cheese with your main!
