Cheesy Mushroom Quiche

This isn’t your average pastry-bottom quiche; the crust gets swapped for a quick-cook box of seasoned brown rice, which gives the bake a nutty, chewy backbone you’d never get from pie dough. Sliced mushrooms and onions go in raw and steam through as the eggs set, releasing their juices into the custard. Grated cheese melts down through the whole thing, threading the rice with stretchy pockets that pull when you cut a square.

Bake until the center is set and the top is just turning golden. The 8×8 pan slices into tidy squares for brunch potlucks or weeknight dinner with a green salad. Vegetarian without feeling like a compromise, and filling enough that one square holds you.

Pro Tips

• Cook the rice fully before mixing, undercooked grains stay crunchy through baking
• Slice mushrooms thin so they cook through and don’t weigh down the custard
• An oiled pan really matters here, the rice on the bottom wants to stick
• Let it rest 10 minutes after baking, the egg sets up firmer and slices cleanly
• Reheat covered at 325°F (165°C); microwaving steams the rice into mush

Variations

• Use wild rice or a wild rice blend for an earthier base
• Stir in baby spinach or chopped kale with the mushrooms for extra greens
• Top with crumbled feta or goat cheese before baking for a tangier finish
