Preheat your oven to 180°C/350°F, suitable for both fan-forced and conventional ovens.
Prepare the loaf tin by lightly greasing a 21 x 11 x 7 cm (8.3 x 4.5 x 2.75") pan with butter or cooking spray, then line it with baking (parchment) paper so the paper overhangs slightly for easier lifting later (Note 3).
For the herb and garlic swirl, combine the extra virgin olive oil, rosemary, parsley, oregano, thyme, crushed garlic, and salt in a small bowl. Stir until you have a thick, spoonable mixture that holds together rather than running off the spoon.
In a medium mixing bowl, whisk together the flour, baking soda, and salt until evenly combined and lump-free.
In a separate bowl or jug, whisk the yogurt, milk, eggs, melted butter, olive oil, and crushed garlic until the mixture is smooth and well blended.
Make a well in the centre of the dry ingredients. Pour in the wet mixture and gently fold with a spatula or wooden spoon until just combined. The batter should be thick but pourable; avoid over-mixing so the bread stays tender.
For the first layer, pour about one-third of the batter into the prepared loaf pan and spread it into an even layer. Dollop one-third of the herb and garlic mixture over the surface, then use a knife to drag and swirl it through the batter, moving up and down and turning some of the batter over to create visible ribbons. Press one-third of the cheese slices randomly into the batter, pushing some pieces deep into the mixture and leaving others partially exposed on top.
Repeat the same process for the second and third layers: add another third of the batter, swirl through another third of the herb mixture, then tuck in another third of the cheese slices. Finish with the remaining batter, herbs, and cheese. Don't worry if some herbs and cheese sit on the surface; they will brown beautifully and add extra flavour and texture.
Place the loaf in the oven and bake for about 30 minutes, or until the top is a rich golden colour. Remove the tin briefly, cover the top loosely with foil to prevent over-browning, then return to the oven and continue baking for a further 20 minutes (for a total of approximately 50 minutes). To check doneness, insert a skewer into the centre of the loaf – it should come out clean or with just a few moist crumbs, but no wet batter.
Let the bread rest in the tin for 5 minutes to settle, then lift it out using the baking paper and transfer it to a wire rack. Allow it to cool for at least 10 minutes so the crumb can firm up before slicing into thick pieces. Serve warm or at room temperature; a smear of butter is optional but always a delicious addition.
