These are super classic and so simple to make. Use leftover rice or thawed frozen rice. For an easy variation, try shredded fontina or Gruyere cheese.
1. When steaming the peppers, ensure they are tender but still hold their shape. Over-steaming can make them too soft and prone to collapsing when filled. The goal is pliable, not mushy.2. For a richer flavor profile, ensure the ground beef is well-browned before adding other ingredients. This creates a fond at the bottom of the skillet, which adds depth to the sauce.3. While the recipe suggests mozzarella, incorporating shredded fontina or Gruyere, as mentioned in the summary, will add a more complex, nutty flavor to the cheesy topping.4. Do not overpack the peppers, as this can lead to uneven cooking of the filling. Leave a little room at the top for the cheese.
