I recently prepared a Cauliflower Mac And Cheese Casserole that completely transformed my view of comfort food. The tender cauliflower and rich cheese sauce come together in an unexpected marriage of flavors with a satisfying crunchy topping. I was surprised by how indulgent each bite felt yet remained refreshingly light.
I’ve always been intrigued by giving classic recipes a new twist. This AMAZING Cauliflower Mac And Cheese blew my mind from the first bite.
I like to start with 1 large head cauliflower, chopped into bite-size florets, which serves as the base of this low carb version. Then, I melt 2 tbsp unsalted butter and quickly mix in 2 tbsp all-purpose flour to build a rich roux before slowly whisking in 1 1/2 cups whole milk.
Next, I fold in 1 cup shredded sharp cheddar cheese, 1/2 cup shredded mozzarella cheese, along with 1/2 tsp garlic powder and 1/2 tsp mustard powder to add a punch of flavor. I adore how this dish explores creative boundaries, reminding me of recipes like Mac And Cheese With Cauliflower Puree and Baked Cauliflower And Cheese, while still staying true to a hearty, cheesy casserole feel.
The optional Parmesan and breadcrumbs on top deliver an extra crunch that makes it uniquely satisfying.
Why I Like this Recipe
I really love how this recipe gives me the comfort of mac and cheese but with a healthier twist thanks to the cauliflower. The creamy blend of cheddar and mozzarella mixed with garlic and mustard powder always makes every bite taste rich and satisfying. I also enjoy the crunch from the optional Parmesan and breadcrumbs, which adds a fun texture that’s not too heavy. Lastly, it’s a straightforward recipe that doesn’t take forever to make and always makes me feel like a chef in my own kitchen.

FAQ
AMAZING Cauliflower Mac And Cheese Recipe Substitutions and Variations
- If you don’t have unsalted butter, try using the same amount of margarine or even olive oil

- Whole milk can be replaced with almond milk or soy milk if you’re looking for a lighter or dairy free alternative
- For the sharp cheddar cheese, you could use Colby jack for a similar taste even if its a tad milder
- If you’d rather change up the topping, swap the Parmesan with Pecorino cheese for a unique flavor kick
Pro Tips
1. Make sure to dry the cauliflower after boiling so that the cheese sauce sticks well and doesn’t get watery which can happen if there is still too much water on the veggies
2. When you are whisking in the milk, keep stirring constantly to avoid those frustrating lumps which tend to form if you are not careful
3. Experiment with a tiny pinch of smoked paprika or even a dash of cayenne pepper into the cheese sauce if you like a little kick, sometimes it makes the flavors pop up more
4. For an extra crunch and flavor kick, lightly toast the breadcrumbs before you sprinkle them on, this simple step can really change the textural experience of the dish
