One last tip

Pro Tips From My Kitchen
- I learned the hard way that really taking your time with the onions is the secret here. Don't rush it! Let them get that deep amber color — that's where all the flavor comes from.
- When browning your ground beef, don't overcrowd the pan or it'll steam instead of sear. Work in batches if you need to, you want a nice sizzle and some golden-brown bits for extra flavor.
- Resist the urge to peek! Keep that foil on tight for the first 30 minutes. That steam is crucial for getting your rice perfectly tender and light and fluffy.
- You'll know it's ready when your kitchen will smell incredible, the sauce bubbles around the edges, and the cheese on top gets all bubbly and golden. It's truly rustic and inviting!
