Rinse the rice under cool water until it runs mostly clear. If time allows, soak the rice in fresh water for 10 minutes, then drain very well.
In a small saucepan, combine the broth, lemon zest, and bay leaf. Warm over low heat until steaming, then cover and keep warm (this helps the rice cook evenly and absorb the lemon aroma).
Heat the olive oil in a medium pot over medium-low. Add the onion and a pinch of salt; cook, stirring often, until translucent and sweet, 5 to 6 minutes. Stir in the garlic and cook 30 seconds more.
Sprinkle in the dried oregano and turmeric; stir for 15 seconds to bloom the spices. Add the drained rice and stir to coat every grain in the aromatic oil; toast for about 1 minute until the edges look slightly translucent.
Pour in the lemon juice and let it sizzle for 30 seconds, stirring to deglaze the pot. Remove the bay leaf from the warm broth and carefully add the hot broth to the rice. Season with 1/2 teaspoon kosher salt and the black pepper (you can adjust later).
Bring to a gentle simmer, then reduce heat to low, cover tightly, and cook for 12 minutes without lifting the lid.
Turn off the heat and let the rice rest, covered, for 10 minutes to finish steaming. Fluff with a fork, taste, and add more salt or pepper if needed.
Garnish with chopped fresh dill (if using) and serve warm.
