Choose bell peppers that are firm and free of blemishes to ensure they hold up well during baking. To save time, cook the rice a day ahead or use leftover rice. For extra flavor, sauté the rice with some garlic and onions before cooking. Parboil peppers for a softer texture if preferred. Use a mix of cheeses for richer taste. Don’t overfill peppers to avoid spillage. Cover baking dish tightly with foil to keep moisture in. Let peppers rest after baking to allow filling to set. Variations include using different meats, vegetarian fillings, grain swaps, spicy additions, and various cheese and herb options. Store leftovers in airtight container; reheat in microwave or oven. Freeze for up to 3 months.
