  • 1 tbsp olive oil
  • 1 head cauliflower, chopped into small pieces
  • 1 yellow onion, diced
  • Salt & pepper to taste
  • 1 tbsp butter
  • 1/3 cup milk
  • 1/3 cup light cream cheese
  • 1 cup cheddar cheese, grated
  • 1 tbsp chopped chives


  • Preheat oven to 450 F and line a baking sheet with parchment paper. Add cauliflower and onions and toss with olive oil, then season with salt and pepper. Bake for 20 minutes, flipping halfway through.
  • While cauliflower is cooking, make the cheese sauce. Melt butter in a large saucepan, then add milk, cream cheese and cheddar cheese, whisking to combine and simmering over low heat for 4-5 minutes until smooth.
  • Remove cauliflower from oven and toss in cheese sauce. Garnish with extra shredded cheddar cheese (optional) and chives then serve and enjoy!



Use a light hand when adding the milk since the cauliflower doesn’t soak up liquids like starchy pasta does.
Cook the cheese sauce over low heat so the milk doesn’t curdle.
Swap out the cauliflower for cauliflower rice.
Feel free to use your favourite type of cheese like Swiss, mozzarella, gouda or parmesan.
Store any leftovers in the fridge for up to 5 days then reheat in the microwave for 1-2 minutes.
Freeze your leftovers for up to 3 months then reheat in the oven or the microwave.
