Helpful cooking tips
- Use long-grain rice, not minute rice — better texture, less mush.
- Don’t stir rice during cooking — it can become sticky.
- Freshly shredded cheese melts creamier than bagged.
- Season at multiple stages, not just the end — flavor stays balanced.
- If using leaner beef or turkey, add a splash of olive oil while browning.
Creative twists
- Southwest version: add taco seasoning, corn, black beans, pepper jack
- French onion style: swap broth for onion soup & top with crispy onions
- Lighter variation: ground turkey, reduced-fat sour cream & cheese
- Vegetable boost: toss in peas, carrots, bell peppers, or spinach
- Bacon upgrade: sprinkle crumbled bacon before baking
