Notes
Tips & Variations
Minute Rice Only: Regular long-grain rice will not cook properly in this recipe.
Chicken Options: You can use boneless, skinless chicken thighs instead of breasts for juicier meat.
Add Veggies: For extra flavor and nutrition, stir in frozen peas, green beans, or mushrooms during the last 30 minutes of cooking
If you have 8 to 10 minutes, sauté the diced onion in a little butter in a skillet until golden and sweet, then stir into the rice mixture. This quick step adds a sweet buttery flavor to the dish.
After cooking serve with Swiss or Gruyère cheese (optional) for a melty French onion soup finish on top.
