Warm the broth: In a small saucepan, keep your broth warm over low heat. This helps the rice absorb liquid evenly.
Sauté aromatics: In a large skillet or saucepan, heat 1 tbsp butter and olive oil over medium heat. Add the diced onion and cook for 2–3 minutes, until translucent. Add garlic and sauté another 30 seconds.
Toast the rice: Stir in Arborio rice and toast for 1–2 minutes, stirring frequently, until edges are slightly translucent.
Deglaze with wine: Pour in the white wine, stirring constantly until mostly absorbed.
Add broth gradually: Begin adding warm broth, one ladle at a time, stirring often. Wait until most of the liquid is absorbed before adding more. Continue until rice is creamy and tender, about 18–20 minutes.
Add lemon and herbs: Stir in lemon zest, lemon juice, parsley, dill, oregano, salt, and pepper. Cook for another 2–3 minutes.
Finish with butter and Parmesan (optional): Turn off heat and stir in the final tablespoon of butter and Parmesan if using. Let it rest for a minute, then serve warm.
