Ingredients You’ll Need
For the Cauliflower:
- Cauliflower: Choose a fresh medium head for best results. It has a mild taste, which absorbs the cheese taste.
- Olive oil: Helps to make the cauliflower nice and golden when roasting. You can use avocado oil as well.
- Salt and pepper: These simple spices enhance the taste. Add garlic powder/cayenne if you want more kick.
For the Cheese Sauce:
- Shredded cheese: The Best flavor comes from sharp cheddar. It melts smoothly, and it thickens the sauce without flour.
- Heavy cream: Makes the sauce creamy. It brings us that luxurious texture we all love.
- Almond milk: Makes the sauce thin to the right consistency. If you don’t need low-carb, you can use regular milk.
- Butter: Gives silky richness to the sauce. Do not forget to use unsalted to control the saltiness.

Equipment You’ll Need
- Baking sheet: A large one gives cauliflower room to brown nicely. Line with foil for easy cleanup.
- Large bowl: For tossing the cauliflower with oil and spices. You’ll use it again to mix everything together.
- Small saucepan: Perfect for making the cheese sauce. The heavy bottom prevents burning.
- Spatula: Better than a whisk for stirring cheese sauce. It prevents the cheese from sticking and clumping.
How to Make Cauliflower Mac and Cheese?
This dish is so easy to make and only has a few simple steps! The high roasting temperature ensures that it is fast, and the easy cheese sauce takes minutes.
Step 1: Prep the cauliflower
Cut cauliflower into small florets about 1 inch in size. This helps them cook faster and makes them more like pasta pieces.
Step 2: Season and roast
Toss the cauliflower with oil, salt, and pepper on a baking sheet. Roast at 450°F for 15-20 minutes until golden and tender.
Step 3: Make the cheese sauce
Combine cheese, cream, milk, and butter in a small saucepan. Heat on low, stirring often until smooth and creamy.

Step 4: Combine
Pour the sauce over the roasted cauliflower in a large bowl. Gently fold together until every piece is coated with cheesy goodness.
Step 5: Serve hot
Sprinkle with fresh black pepper if desired. Enjoy right away while it’s hot and the sauce is perfectly creamy.

Tips for the Best Cauliflower Mac and Cheese
- Cut florets small and evenly for faster cooking and better sauce coating. Aim for bite-sized pieces like regular mac and cheese.
- Give cauliflower plenty of space on the baking sheet. Crowding leads to steaming instead of roasting, and you want those crispy edges.
- Use a spoon or spatula for the cheese sauce, not a whisk. Whisks trap shredded cheese and make lumps.
- Adjust sauce thickness easily by adding more cheese to thicken or more milk to thin. The sauce will thicken as it cools.
- Fold gently when mixing the sauce with the cauliflower to keep the tender florets intact. Rough mixing breaks them into mush.
Variations and Substitutions
- Cheese options: Try Gruyere, Gouda, or Monterey Jack instead of cheddar. Mix cheeses for a complex flavor, like cheddar with parmesan.
- Milk choices: Use coconut milk beverage for nut-free, or regular milk if not following keto. The sauce works with many liquid options.
- Add protein: Mix in cooked bacon bits or shredded chicken. This addition turns the side dish into a complete meal.
- Spice it up: Add a dash of paprika, nutmeg, or cayenne pepper. These spices create depth of flavor without overwhelming.
- Crispy topping: Sprinkle with more cheese and crushed pork rinds. Broil briefly for a crispy, golden crust like traditional mac.
Make-Ahead and Storage Tips
- Prep ahead: Roast cauliflower and make sauce separately. Store in the fridge up to 2 days, then combine and reheat when ready.
- Refrigerate leftovers: Keep in an airtight container for up to 4 days. The sauce may thicken when cold, but will loosen when reheated.
- Best reheating methods: Use a microwave for quick meals or oven at 350°F. Add a splash of milk if the sauce seems too thick.
- Not freezer-friendly: The cheese sauce texture changes when frozen and thawed. Enjoy fresh or as refrigerated leftovers for best results.
- Refresh leftovers: Add a sprinkle of fresh cheese when reheating. This trick makes day-old cauliflower mac taste almost new again.
Serving Ideas
- Comfort food pairing: Serve with chicken nuggets or fried chicken. These classics create a kid-friendly meal that adults love too.
- Weeknight dinner: Pair with simple baked chicken legs or meatloaf. This combo makes an easy, satisfying dinner the whole family enjoys.
- BBQ companion: Great alongside burgers, hot dogs, or BBQ chicken. The creamy dish balances smoky, grilled flavors perfectly.
- Holiday side: Bring to potlucks or holiday meals. This lighter option gives guests a low-carb choice among heavy dishes.
- Solo meal: Enjoy a big bowl all by itself for lunch. The protein from cheese makes it more filling than you might expect.
