Whether served as a side dish or the main attraction, it’s guaranteed to make any meal memorable.
The Magic of Mushrooms
Mushrooms are the star of the show — not only for their deep, savory flavor but also for their nutritional profile. These little wonders are naturally low in calories, high in fiber, and a great source of B vitamins and selenium. They’re also one of the few plant-based sources of vitamin D, supporting immune health and energy metabolism.
When baked with cheese and whole-wheat panko breadcrumbs, mushrooms soak up all the flavors while maintaining their tender bite. The result? A dish that’s comforting, nourishing, and wonderfully satisfying.

Test Kitchen Tips
1. Choose the Right Mushrooms:
Portobello or cremini mushrooms give the best meaty texture. Clean them with a damp paper towel rather than washing to prevent sogginess.
2. Prep Smart:
Remove the stems and gills before filling to create more space for the cheese mixture and prevent excess moisture.
3. Cheese Swap:
While mozzarella and Gruyère are classic, you can experiment with cheddar, Swiss, or fontina for a flavor twist.
4. Crunch Factor:
Whole-wheat panko breadcrumbs give that irresistible crunch. Mix them with a touch of olive oil before baking for a perfect golden finish.
5. Make Ahead:
Assemble your gratin in advance, cover tightly, and refrigerate. Bake just before serving for stress-free entertaining.
