Creamy Cauliflower Mac and Cheese Recipe
Introduction
Creamy Cauliflower Mac and Cheese offers a comforting twist on the classic dish by swapping traditional pasta for tender cauliflower florets. This recipe delivers a rich, cheesy sauce with a crispy, golden top—a perfect way to enjoy a lighter yet indulgent meal.

Ingredients
- 8 cups cauliflower, chopped into 1-inch florets (about 1 large head)
- 2 tablespoons unsalted butter
- 3 tablespoons flour
- 2 cups whole milk
- 1 ½ teaspoons kosher salt
- 1 ½ teaspoons garlic powder
- ½ teaspoon smoked paprika
- ¼ teaspoon nutmeg
- 2 ½ cups cheddar cheese, shredded (divided)
- ¼ cup Panko breadcrumbs
- 2 tablespoons chives or green onions, finely chopped (for topping)
Instructions
- Step 1: Preheat the oven to 375°F (190°C).
- Step 2: Place the cauliflower florets in a microwave-safe bowl with about an inch of water. Cover with a plate and microwave on high for 8 minutes. Drain well and set aside.
- Step 3: In a large saucepan, melt the butter over medium heat. Stir in the flour and cook for about 2 minutes to remove the raw flour taste.
- Step 4: Reduce the heat to medium-low. Slowly whisk in the milk, adding it a little at a time, until fully incorporated. Continue cooking until the sauce thickens and becomes smooth.
- Step 5: Remove the saucepan from heat. Stir in the kosher salt, garlic powder, smoked paprika, and nutmeg until well combined. Add 2 cups of shredded cheddar cheese and mix until melted and smooth.
- Step 6: Add the cooked cauliflower to the cheese sauce and stir gently to combine. Transfer the mixture to a baking dish. Sprinkle the remaining ½ cup of shredded cheese and Panko breadcrumbs evenly over the top.
- Step 7: Bake uncovered for 25 minutes, or until the cheese is bubbly and starting to brown. For an extra golden top, switch the oven to broil and cook for 2-3 minutes more—watch closely to prevent burning.
- Step 8: Remove from the oven and sprinkle with chopped chives or green onions. Let the dish cool slightly before serving. Enjoy with a fresh side salad for a complete meal.
Tips & Variations
- Shred your own cheese from a block for better melting and richer flavor compared to pre-shredded varieties.
- For extra creaminess, stir in a spoonful of cream cheese or Greek yogurt along with the cheddar.
- Try mixing in cooked bacon or sautéed mushrooms for added texture and taste.
- If you prefer a spicier kick, add a pinch of cayenne pepper to the cheese sauce.
Storage
Store leftover cauliflower mac and cheese in an airtight container in the refrigerator for up to 3 days. To reheat, warm it gently in the oven at 350°F (175°C) until heated through, or microwave in short intervals while stirring to ensure even warming.

Ingredients
Cauliflower
- 8 cups cauliflower, chopped into 1-inch florets (about 1 large head)
Sauce
- 2 tablespoons unsalted butter
- 3 tablespoons flour
- 2 cups whole milk
- 1 ½ teaspoons kosher salt
- 1 ½ teaspoons garlic powder
- ½ teaspoon smoked paprika
- ¼ teaspoon nutmeg
- 2 ½ cups cheddar cheese, shredded (divided)
Topping
- ¼ cup Panko breadcrumbs
- 2 tablespoons chives or green onions, finely chopped (for topping)
Instructions
- Preheat Oven: Preheat your oven to 375°F (190°C) to prepare for baking the dish later.
- Steam Cauliflower: Place the chopped cauliflower florets in a microwave-safe bowl, add about an inch of water, and cover with a microwave-safe plate. Microwave on high for 8 minutes, then drain thoroughly and set aside.
- Make Roux: In a large saucepan, melt the unsalted butter over medium heat. Stir in the flour and cook for about 2 minutes to remove the raw flour taste while stirring constantly.
- Add Milk: Reduce heat to medium-low. Slowly whisk in the whole milk a little at a time until fully incorporated. Continue cooking, whisking frequently, until the sauce thickens into a smooth consistency.
- Season and Add Cheese: Remove the sauce from heat. Stir in kosher salt, garlic powder, smoked paprika, and nutmeg to evenly blend the flavors. Then, add 2 cups of the shredded cheddar cheese to the sauce and stir until melted and smooth.
- Combine Cauliflower and Sauce: Add the steamed cauliflower to the cheese sauce and gently mix to coat all florets evenly. Transfer this mixture to a baking dish.
- Add Topping and Bake: Sprinkle the remaining ½ cup of shredded cheddar cheese and the Panko breadcrumbs evenly over the top. Bake uncovered for 25 minutes until the cheese is bubbly and starting to brown.
- Broil for Browning: For a crispier top, switch the oven to broil and cook the dish for an additional 2-3 minutes until the cheese and breadcrumbs turn a golden brown color.
- Garnish and Serve: Remove from the oven and sprinkle with finely chopped chives or green onions. Allow the dish to cool slightly before serving. Pair with a fresh side salad for a complete meal.
