How to Make Gluten Free Creamy Cauliflower Cheese
Start by preheating the oven to 200°C and bring a large pot of water with some salt to the boil.
Prepare the cauliflower
Remove the leaves from the cauliflower then cut it into medium sized pieces and place in a colander. Rinse the cauliflower then add it to the boiling water and boil for 2 - 3 minutes. Strain the cauliflower and set aside.
Prepare cornflour
In a cup, combine the cornflour with 4 tablespoons of milk from the total milk amount and mix until smooth. Set aside.
Start preparing the cheese sauce
Add the vegetable oil to a saucepan and place the pan on a medium heat. Add in the chopped onions and cook until soft. To the pan, add the butter and allow to melt. Pour the rest of the milk into the pan then pour in the cornflour mixture and continue to stir. Once the sauce has thickened, reduce the heat and stir in the single cream.
Season the sauce and add the cheese
Mix in the salt, black pepper, Dijon mustard and half the cheese. Once the cheese has melted and the sauce has thickened, remove the sauce from the heat.
Combine the cheese sauce with the cauliflower
Add the cauliflower to the pot with the cheese sauce and stir to ensure all the cauliflower gets coated with the cheese sauce. Transfer the cauliflower cheese to a 8 x 8 inch baking dish and top with the rest of the cheese.
Bake the cauliflower
Bake for 35 – 40 minutes or until golden brown in colour then remove from the oven and allow to stand for 10 minutes before serving.
Recipe Tips
- I use a 8 x 8 inch or 20 x 20 cm size oven dish. Your dish doesn't have to be exactly the same just close.
Storage
Any leftover cauliflower cheese should be cooled then stored in the fridge and used within 2 days. Reheat in the microwave or oven.
