Seaweed pesto pizza with red onion

pizza with red onion
Pizza needs no introduction! We’ve gone all out with this recipe – it has seaweed in the dough, seaweed in the tomato sauce, and seaweed on top! There’s a little more effort involved with making your own pizza dough but trust us – it is SO worth the extra effort. Of course, if you’re looking for a quick and easy meal then it’s fine to buy a ready-made pizza base from the store, but then you miss out on all the added seaweed goodness! This recipe is one to use if you’re throwing a pizza party, as the quantities for the tomato sauce will yield about 5 portions. If you don’t want to make 5 pizzas, then the sauce can be frozen and used at a later date.
Makes 1 pizza, with sauce to spare


400g chopped tomatoes
20g balsamic vinegar
5g sugar
50g olive oil
5g Smoked Seaweed Salt
1 tbsp tomato purée
5 garlic cloves, minced
190 seaweed pizza dough
Grated mozzarella
1 small red onion, sliced into rounds
Seaweed pesto
1 lemon


First, make the sauce. Heat the olive oil over a low heat and gently fry the garlic until it begins to caramelise. Add the balsamic vinegar and tomato purée, and simmer for a further 2 minutes, stirring continuously. Add the rest of the ingredients, simmer for a further 5 minutes, then remove from the heat and allow to cool. Blend in a food processor before using on your pizza.
Preheat the oven to 300°C.
Shape the dough into a circle roughly 30cm in diameter. Spread a ladle-full of the tomato sauce onto the base, then scatter a handful of grated mozzarella cheese on top, followed by the red onions.
Bake the pizza for 10 minutes until the crust is golden and the cheese is bubbling. Remove from the oven, and dress with the seaweed pesto and some lemon zest before serving.
