1. Start by dissolving the sugar in lukewarm water, then add your yeast and mix. Let it sit in a warm dark spot (like inside a turned-off oven) for 5-10 minutes or until there’s froth on the top.
2. Grab a large bowl and add the flour. Make a well in the center with a wooden spoon and pour in the yeast mixture and 3 tbsp of olive oil. Give it a good mix with a wooden spoon and before everything is well combined, add the salt. Mix for a few minutes until everything comes together. The dough should be wet and sticky, so don’t add any more flour! If you do, it should only be a tbsp or so. Drizzle the remaining 2 tbsp of olive oil over the dough and grease the sides of the bowl. Cover with saran wrap and refrigerate overnight or for up to 72 hours, I refrigerated mine for 50 hours.
3. When you want to bake the focaccia, remove the dough from the fridge and transfer it to a greased large baking sheet with the help of a greased spatula. For a thinner focaccia, I used a 33 x 42 cm baking sheet. Let the dough proof at room temperature for 45 minutes to an hour. In the meantime, we can prepare our topping.
4. For the topping, chop the walnuts and sun-dried tomatoes into medium chunks, and set aside. Wash and dry the herbs and garlic, then roughly chop them. In a pan, add the chopped walnuts, sun-dried tomatoes, herbs, garlic, spices, and olive oil. Give everything a stir and place on medium heat. The topping should only be sauteed for a few minutes or until everything is fragrant and the herbs have turned bright green.
5. Preheat the oven to 220C or 428F. Once the dough is done proofing, lightly sprinkle the topping evenly across. Then lightly drizzle some olive oil and with greased fingers, start dimpling. Gently push your fingers into the dough halfway to create dimples. Lastly, sprinkle the sesame and nigella seeds over the focaccia. Once the oven is preheated, bake the focaccia for 27 minutes. If the baking sheet you’re using is smaller than mine and therefore you have a thicker dough, you will need to bake your focaccia for longer. You can tell it’s ready when the edges are golden brown and the top is lightly toasted.
6. When you take it out of the oven, lightly drizzle it with olive oil again and let it cool for at least 10 minutes before cutting into it. You can serve this with dipping oil like a delicious zaatar oil or with some fresh white cheese and herbs.
This focaccia tastes even better when enjoyed with friends and family.
