Preheat oven to 220°C/425°F.
Place the whole, unpeeled sweet potatoes in the oven for 35-45 minutes, or until a knife can pierce all the way through the skin and flesh.
While the potatoes are cooking, mix the ground flaxseeds with the warm water. Give it a stir and set aside for 5 minutes. This is our flaxseed “egg” mixture.
Next, tip the oats into a food processor and grind until completely smooth. This step can take longer than you would expect for grit-free oat flour. If you pinch some of the oat flour between your fingers, it should be as grain-free as possible. Tip the flour into a large bowl.
Add the garlic powder and any seasoning to the oat flour.
Once the sweet potatoes are cooked, remove from the oven and allow to cool. Keep the oven at the same temperature.
Peel the skin off the cooled sweet potatoes, scoop out the flesh and add to the flour. Mashup the soft sweet potatoes. Then, add the flaxseed egg mixture and, using a spoon, stir the mixture into a dough.
If the dough is too sticky, you can add some flour at this point to turn into a pliable dough.
Dust your work surface with flour. Tip the dough onto the surface and knead until smooth.
Cut the dough in half, as this recipe will make 2 pizza bases for 2 people.
Roll out each segment into a round, pizza shape. You want the pizza base to be about 0.5cm/0.2” thick. If you’d like a thicker crust, you can crimp the edges slightly by folding over the edge onto itself.
Repeat the previous step with the second ball of dough, if using.
Place pizza bases face down onto the baking tray.
Cook the base in the oven for 20-25 minutes, or until it starts to turn a light golden-brown.
Once the pizza base is cooked, remove the pizza base from the oven and let cool for 1 minute.
Once cooled, flip the base upside down using a spatula, or similar. Now spray or brush the top lightly with some olive oil.
Spread the tomato puree with a spoon all over the base. Top the pizza with your favourite toppings! I’ve used mushrooms, grilled artichokes, sweetcorn and vegan cheese. Add some dried or fresh herbs, salt and pepper, to taste.
Place the pizza back in the oven and cook for a further 10-15 minutes or until the cheese has melted and the crust is golden brown.
Now, you may be eager to eat your pizza at this stage but, if you can wait, set the pizza aside for one minute to allow the toppings to firm up slightly…Did you wait for a minute? Excellent! Slice your well-deserved, delicious pizza and enjoy!
