Notes

For a richer flavor, consider making a béchamel sauce from scratch instead of condensed soups, incorporating a blend of cheeses like Gruyere with Muenster for a more complex profile. When sautéing celery, onion, and garlic, take your time to properly caramelize them, enhancing their sweetness and depth. To prevent a soggy casserole, ensure your cooked rice is al dente and well-drained. For the panko topping, toast it separately with butter and a pinch of dried herbs (like thyme or parsley) before sprinkling over the casserole in the final 10-15 minutes of baking for maximum crispness and aroma. Serve with a sprinkle of fresh parsley for a vibrant finish.
