Craving the comfort of mac and cheese but sticking to your low-carb goals? Get ready to indulge guilt-free with our Healthy Cauliflower Mac and Cheese Bake! This dish is about to become your new favorite comfort food hack.
My mom occasionally made cauliflower mac and cheese when I was growing up. It was yummy, but the water in the cauliflower diluted the cheese sauce, leaving it watery. In this recipe, I use a low-carb thickener, instant clearjel, instead of flour. It doesn’t break down in the oven, and the cheese sauce is super creamy, thick, and yummy. Imagine sinking your fork into a golden, bubbly casserole where cauliflower florets are coated with all that cheesy goodness. It’s creamy, it’s delicious, and yes, it’s low in carbs.
Okay, let’s discuss why I say this recipe is healthy when it has all that cheese and heavy cream. Here is the uncomfortable truth about fats vs. carbs: Carbs are worse for us than fats. If we adhere to a very low-carb diet, here is what happens in our bodies.
Metabolic shift
- When you significantly reduce carbohydrate intake, your body enters a state called ketosis.
- In ketosis, your body shifts from using glucose as its primary fuel source to burning fat for energy.
Fat-burning efficiency
- During ketosis, your body becomes more efficient at using fat stores for energy.
- This can lead to increased fat loss, especially in the initial stages of the diet.
Insulin regulation
- Low-carb diets result in lower insulin levels.
- Lower insulin levels can make accessing and burning stored fat easier for your body.
Potential drawbacks
- While effective for fat-burning, very low-carb diets may not suit everyone.
- Some people may experience side effects like fatigue, headaches, or constipation.
- It’s crucial to ensure you’re still getting essential nutrients from other food sources.

Ingredients for Healthy Cauliflower Mac and Cheese
Cauliflower: The star of our dish! Packed with fiber, vitamins C and K, and antioxidants, cauliflower supports digestive health, boosts immunity, and fights inflammation. Its low-carb nature helps maintain stable blood sugar levels, crucial for longevity.
Butter: While it should be consumed in moderation, butter contains fat-soluble vitamins A, E, and K2. Vitamin K2 is particularly important for heart and bone health as we age.
Heavy Cream: Rich in fat-soluble vitamins and conjugated linoleic acid (CLA), which may have anti-inflammatory properties. The fat content also helps with the absorption of fat-soluble vitamins from other ingredients.
Almond Milk: A great source of vitamin E, an antioxidant that supports skin health and may help protect against cognitive decline. It’s also low in calories, supporting weight management.
Cheddar Cheese: High in protein and calcium, cheddar cheese supports muscle and bone health. It also contains conjugated linoleic acid, which may have anti-cancer properties.
Parmesan Cheese: Rich in calcium and protein, Parmesan also contains probiotic bacteria that support gut health, a key factor in longevity.
Cream Cheese: Provides a good dose of vitamin A, important for eye health and immune function. Its protein content also supports muscle maintenance.
Dijon Mustard: Contains turmeric, which has powerful anti-inflammatory and antioxidant properties. It may help in preventing chronic diseases associated with aging.
Garlic Powder: Garlic compounds have been linked to improved heart health and may help lower blood pressure, crucial for longevity.
Instant Clearjel: While primarily used as a thickener, instant clearjel is a soluble fiber that can help stabilize blood sugar levels and support digestive health.
Parsley: Rich in vitamins A, C, and K, parsley is a nutrient-dense herb that supports bone health, blood clotting, and provides antioxidants.

Step by Step Instructions for Healthy Cauliflower Mac and Cheese.
Preheat your oven to 375°F (190°C) and grease a 9×13 inch baking dish.
Steam the cauliflower florets until tender but still firm, about 5-7 minutes. Drain well and set aside. Once they are cooked, pat them dry to remove and moisture. The moisture will make your cheese sauce watery.
In a large saucepan, melt the butter over medium heat. Add the heavy cream and almond milk, whisking to combine.
Stir the Instant Clearjel into the shredded cheddar cheese. Gradually add the shredded cheddar and 1/2 cup of Parmesan cheese, stirring constantly until melted and smooth. Grate your own cheese instead of using pregrated cheese as the pregrated cheese had anticaking chemicals added to it.
Add the cream cheese, Dijon mustard, and garlic powder. Whisk until the cream cheese is fully incorporated and the sauce is smooth.
Season with salt and pepper to taste.
Add the steamed cooled and dried cauliflower florets to the baking pan.
Pour the cheese sauce over the cauliflower in the baking dish. Top with the remaining 1/4 cup of finely grated Parmesan cheese.
Bake for 20-25 minutes, or until the top is golden brown and bubbly.
Remove from the oven and let your healthy cauliflower mac and cheese cool for 5 minutes. Garnish with chopped parsley before serving.
Tips for Success
- For extra protein, add some cooked, diced chicken or crispy bacon bits.
- Experiment with different cheese combinations like Gruyère or fontina for varied flavors.
- For a crispy top without breadcrumbs, sprinkle crushed pork rinds or almond flour mixed with melted butter before baking.
