Save to Pinterest The first time I made this, my husband actually asked what restaurant I ordered from. I laughed so hard I nearly dropped the baking dish on the floor. He is a die hard mac and cheese purist, the kind of guy who grew up on the blue box stuff and still considers it comfort food royalty. When I told him it was cauliflower, he looked at me like I had confessed to a magic trick. Now he requests this more than the real thing, which still feels like a small victory every single time.
I brought this to a potluck last fall and watched three different people go back for seconds before someone finally worked up the courage to ask what made it so creamy. The best part was watching their faces when I said cauliflower flour and milk. My friend Sarah, who has been doing keto for years, actually wrote down the recipe on a napkin right there at the table. Something about that moment, watching people genuinely enjoy food that happens to be good for you, stuck with me.
Ingredients
- Cauliflower: One large head gives you about six cups of florets, which is the perfect ratio for all that cheese sauce without getting lost in the mix
- Butter: Two tablespoons builds the foundation for your roux, and unsalted lets you control the seasoning exactly
- Almond flour: This creates a silky smooth sauce thickener without the carbs of regular flour, and coconut flour works beautifully if you need nut free
- Whole milk: The fat content here makes all the difference in how the cheese melts and clings to every floret
- Sharp cheddar: The sharper the better here because that tang cuts through the richness and keeps things interesting
- Mozzarella: This is what gives you those incredible cheese pulls when you scoop a serving
- Grated Parmesan: Two separate portions, one for the sauce and one for that golden crusty top that everyone fights over
- Garlic and onion powder: This duo creates that savory depth that makes homemade cheese sauce taste like something from a restaurant
- Ground mustard: Just a quarter teaspoon wakes up all the cheese flavors without making things taste mustardy
Instructions
- Preheat your oven to 400°F and grab a 9x13 baking dish:
- Give that dish a quick swipe of butter or oil while the oven comes up to temperature
- Get a large pot of salted water boiling:
- Cook those cauliflower florets for just four to five minutes until they give a little when you poke them with a fork
- Drain the cauliflower and pat it completely dry:
- Excess water will make your sauce thin and sad, so take the time to really dry everything off
- Arrange cauliflower in your prepared dish:
- Spread everything into an even layer so the cheese sauce can reach every single piece
- Melt butter in a saucepan over medium heat:
- Whisk in the almond flour and let it cook for one full minute until it smells slightly nutty
- Slowly whisk in the milk:
- Keep whisking until the sauce thickens enough to coat the back of a spoon, about two or three minutes
- Turn the heat down to low:
- Add all three cheeses gradually, stirring until each handful melts before adding more
- Stir in garlic powder, onion powder, ground mustard, salt, and pepper:
- Taste the sauce and adjust the seasonings before you pour it over the cauliflower
- Pour the cheese sauce over the cauliflower:
- Gently fold everything together until every floret is wearing a little cheese jacket
- Sprinkle the extra cheeses on top:
- This layer is what transforms into that golden crusty topping worth waiting for
- Bake for fifteen to twenty minutes:
- You want the sauce bubbling up the sides and the top showing some golden spots
- Finish with parsley if you are feeling fancy:
- The green against all that golden cheese makes everything look restaurant quality
Save to Pinterest Last winter my sister came over feeling completely defeated by a new diet plan, the kind where everything feels like restrictions and rules. I made this without telling her what it was, watching her face light up with that first bite. She took three servings before finally asking what was in it. The best part was seeing her realize that eating differently does not have to mean giving up comfort.
Make It Your Own
Sometimes I throw in a handful of crispy bacon pieces right before baking, and other times I have added steamed broccoli for extra veggie power. The cheese sauce is incredibly forgiving, which means you can play around based on what you have in the fridge or what your family loves.
The Perfect Texture
I have learned that roasting the cauliflower first instead of boiling it gives you a slightly nuttier flavor and firmer texture that holds up beautifully to all that sauce. If you have the extra time, toss the florets in olive oil and roast at 400°F for about fifteen minutes before adding the cheese sauce.
Serving Ideas
This dish somehow manages to feel like a full meal on its own, but I love serving it alongside grilled chicken or a simple green salad with that bright vinaigrette. The richness of the cheese plays so nicely against something fresh and acidic.
- Let the dish rest for five minutes after baking so the sauce sets up slightly
- Reheat leftovers with a splash of milk to bring that creamy texture back to life
- The topping gets soggy in the fridge, so run it under the broiler for two minutes to recrisp
