- Shredded Sharp Cheddar Cheese: The bold flavor of sharp cheddar gives this dish its iconic cheesy bite.

How to Make Keto Cauliflower Mac and Cheese
Step 1: Prep and Blanch the Cauliflower
Start by preheating your oven to 375°F (190°C). Bring a large pot of salted water to a boil, add your cauliflower florets, and cook them for about five minutes. You want them just fork-tender, not mushy, so they hold their shape after baking. Drain thoroughly and set aside—getting rid of excess water here is key to avoiding a watery casserole.
Step 2: Make the Creamy Cheese Sauce
While your cauliflower drains, melt the butter in a large skillet over medium heat. Add the heavy cream and softened cream cheese, whisking constantly until everything is smooth and silky. Next, toss in the shredded sharp cheddar and mozzarella, stirring until the cheese is completely melted and the sauce is creamy. This step is where the magic happens: your kitchen should start smelling fantastic!
Step 3: Season the Sauce
Sprinkle in the garlic powder, onion powder, and a good pinch of salt and pepper. Stir well to distribute the seasonings evenly. Taste the sauce and adjust the seasoning as needed—this is your chance to personalize the flavor to your liking before the cauliflower goes in.
Step 4: Combine Cauliflower and Cheese Sauce
Add your cooked, well-drained cauliflower florets to the skillet and gently fold them into the cheese sauce. Make sure every single piece is coated in that dreamy, velvety mixture. This step sets the stage for the ultimate Keto Cauliflower Mac and Cheese experience—don’t rush it!
Step 5: Bake to Golden Perfection
Transfer everything to a greased baking dish, then sprinkle the grated Parmesan evenly across the top. Slide the dish into your preheated oven and bake for 15 to 20 minutes, until the cheese is bubbling and the top is just starting to turn golden. For an extra crispy finish, broil for the last couple of minutes—just keep a close eye so it doesn’t burn!
Step 6: Finish and Serve
Once your Keto Cauliflower Mac and Cheese is looking irresistibly golden and bubbly, take it out of the oven and let it sit for a few minutes before serving. If you’d like, sprinkle with fresh chopped parsley for a touch of color and freshness. Dig in and enjoy every creamy, cheesy bite!
How to Serve Keto Cauliflower Mac and Cheese
Garnishes
A sprinkle of chopped fresh parsley adds color and a hint of herbaceous flavor that balances the richness of the cheese. You can also dust on a little extra Parmesan or a pinch of smoked paprika for a subtle kick and a pretty finish. Garnishes are your chance to make your Keto Cauliflower Mac and Cheese look as good as it tastes!
Side Dishes
This dish is hearty on its own, but it pairs beautifully with simple sides like a crisp green salad or roasted chicken. For a full keto feast, try serving alongside grilled sausage, sautéed greens, or a tomato cucumber salad—the freshness of the sides complements the creamy, cheesy main perfectly.
Creative Ways to Present
For dinner parties or meal prep, portion Keto Cauliflower Mac and Cheese into individual ramekins before baking for a restaurant-style touch. Or, serve it as a filling for stuffed bell peppers for a colorful twist. This recipe is flexible, so let your creativity guide you and make each presentation uniquely yours!
Make Ahead and Storage
Storing Leftovers
Store any leftover Keto Cauliflower Mac and Cheese in an airtight container in the refrigerator for up to three days. The flavors meld together even more as it sits, so leftovers are just as crave-worthy as the first helping.
Freezing
If you’d like to freeze your mac and cheese, let it cool completely, then transfer to a freezer-safe dish. Wrap tightly and freeze for up to two months. For best texture, freeze before baking, then thaw overnight in the fridge and bake fresh when you’re ready to enjoy.
Reheating
To reheat, simply warm portions in the oven at 350°F until heated through, or microwave individual servings for a quick lunch. If the sauce thickens up too much, add a splash of cream to bring back its creamy texture.
