Carbs in Cauliflower
Cauliflower is a great low carb vegetable and is used in many, many low carb dishes. With just 3g net carbs a 100 gram serving it is also a high fibre vegetable.
The recipe may have a few steps to make it but the ingredients are simple.
- Cauliflower - this recipe uses a 1lb sized cauliflower. If you are using a large cauliflower you may need to increase the ingredients for the mushroom covering and low carb pastry.
- Mushrooms - any variety of mushrooms will work and you can also mix varieties together.
- Walnuts - these could be replaced with pecans or almonds.
Preparing the Roasted Cauliflower Wellington
Roasting the cauliflower is essential as it helps draw any moisture out of the cauliflower and stops it becoming a soggy mush when baked in pastry.
The cauliflower needs to be chilled once roasted making this a great make ahead dish.
Rub the cauliflower head in the herb and oil mixture and roast.
Cook the mushrooms, onion and garlic in a frying pan.
Place the nuts, cooked mushrooms and herbs in a food processor to blitz into a paste.
Once the cauliflower is chilled, cover it in the walnut mushroom paste.
Making a Keto Cauliflower Wellington
This cauliflower dish can be made ahead until you are ready to cover with fathead dough pastry and bake.
Melt the mozzarella, add the almond flour and baking powder. Form into a dough.
Roll out the pastry in between 2 layers of parchment paper.
Place the pastry over the mushroom covered cauliflower and cover it whole.
Seal any edges and decorate. Brush with a beaten egg and bake.
The herbs in the mushroom coating can be varied and fresh or dry can be used. Try rosemary or basil for extra flavor.
For the mushrooms we used chestnut mushrooms but try a variety for a stronger flavor. Porcini mushrooms would add a stronger taste or try portobello mushrooms.
Any leftovers can be stored in the fridge. Cover the dish with foil and it should last up to 3 days. Reheat in the oven until the dish is warm throughout.
The Mozzarella cheese can be melted on the stove in a bain marie if you don't want to use a microwave.
