1. For truly crispy onions, ensure they are thinly and evenly sliced. Tossing them frequently during baking promotes uniform browning and crispness. If they start to burn, lower the oven temperature slightly. 2. The ice bath for green beans is crucial to halt cooking and preserve their vibrant color and crisp-tender texture. Do not skip this step. 3. When cooking the mushroom sauce, allow the mushrooms to release their liquid fully before adding the flour; this deepens their flavor. Use freshly ground nutmeg for superior aroma. 4. Serve immediately to maintain the casserole's warmth and the onions' crispness.
