Frequently Asked Questions
- → How do I know when onions are properly caramelized?
- They should be a deep golden brown and very soft, taking about 20-25 minutes. Don't rush this step - it's where all the flavor comes from!
- → Can I make this ahead of time?
- Yes! You can caramelize the onions a day ahead. When reheating the completed dish, add a splash of broth to keep it moist.
- → Why rinse the rice?
- Rinsing removes excess starch and helps prevent the rice from becoming sticky or gummy. Keep rinsing until the water runs clear.
- → What can I serve this with?
- It pairs beautifully with grilled meats, roasted chicken, or as a vegetarian main dish. The rich onion flavor complements most proteins.
- → Can I use different types of rice?
- Yes, but cooking times may vary. Brown rice will need more liquid and time, while basmati or jasmine rice work similarly to regular long-grain.
