A wholesome vegetable-studded casserole built on a savory rice-and-cheese crust, bound with egg substitute and topped with melted cheddar.

Tips
Press the rice crust firmly into the dish to create a solid base that won't crumble when you pour the custard mixture over it.
Don't skip steaming vegetables separately; it prevents excess moisture from soaking the crust and keeps textures distinct.
Good to Know
Cover and refrigerate up to 3 days. Reheat covered at 325F until warmed through, 15-20 minutes.
Assemble through step 6 but do not bake. Cover and refrigerate overnight. Bake as directed, adding 5-10 minutes if starting from cold.
Serve directly from the baking dish while hot. Pairs with a green salad or crusty bread.
Common Mistakes
Do not skip the initial 10-minute bake of the crust; this sets its structure and prevents sogginess.
Do not over-steam vegetables; they will continue cooking in the oven and may become mushy if too soft initially.

FAQ
Can I make this ahead?
Yes. Assemble through the vegetable step, cover, and refrigerate overnight. Bake the next day, adding 5-10 minutes since it starts cold. Fully baked leftovers store for 3 days covered.
What if I don't have egg substitute?
Use 2 whole eggs plus 2 tablespoons water as a 1:1 volume swap. The flavor will be slightly richer and nutrition will shift to include dietary cholesterol.
How long can I keep it and can I freeze it?
Refrigerate covered for up to 3 days. Freezing is not recommended; the custard becomes grainy and vegetables lose texture after thawing.
