Description

This Cauliflower Mac and Cheese recipe is the ultimate low-carb, keto-friendly comfort food. Featuring roasted cauliflower and a rich, creamy cheese sauce, it's a healthy alternative to traditional mac and cheese that doesn’t skimp on flavor.


Ingredients

  • 1 large head of cauliflower, cut into bite-sized pieces
  • 2 tablespoons olive oil
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • Salt and pepper, to taste
  • 1 cup heavy whipping cream
  • 4 ounces cream cheese, softened
  • 2 cups shredded cheddar cheese

Instructions

  1. Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper.
  2. Toss cauliflower with olive oil, garlic powder, onion powder, salt, and pepper. Spread on baking sheet.
  3. Roast for 20–25 minutes, until tender and lightly golden.
  4. In a saucepan over medium heat, heat heavy cream and cream cheese, stirring until smooth.
  5. Add 1.5 cups shredded cheddar to the sauce; stir until melted and creamy.
  6. Fold roasted cauliflower into the cheese sauce until coated.
  7. Transfer to a baking dish, top with remaining 0.5 cup cheddar.
  8. Bake for 10–15 minutes, until bubbly and golden.
  9. Cool slightly before serving.

Notes

  • Add grilled chicken, or sausage for protein.
  • Swap cheddar with gouda, mozzarella, or pepper jack for variety.
  • Add jalapeños or hot sauce for a spicy version.
  • For crunch, top with keto-friendly breadcrumbs before baking.
  • Use frozen cauliflower if needed—thaw and drain well first.
