Perfect for weeknight dinners or brunch when you need something warm and satisfying without heavy techniques. This version keeps the preparation straightforward while delivering restaurant-quality texture through proper baking temperature.
Ingredients

Tips
For optimal rise and texture, ensure eggs are fully beaten to incorporate air before mixing. Use room-temperature eggs for better emulsion with milk.
Test doneness with a knife inserted near center; it should come out clean or with just slight custard residue. Overbaking causes excessive browning and dry texture.
Layer mushrooms evenly with onions during sauteeing to distribute umami flavor and prevent soggy pockets in the finished dish.
Good to Know
Cover and refrigerate up to 2 days. Reheat covered at 325F for 10-15 minutes until warmed through.
Prepare rice in advance. Mix all ingredients except paprika up to 4 hours ahead. Pour into dish and refrigerate. Add 2-3 minutes to bake time if starting from cold.
Serve immediately while souffle holds its rise. Pairs well with simple green salad, roasted vegetables, or crusty bread to soak up creamy interior.
Common Mistakes
Do not skip preheating the oven to avoid uneven rising and dense centers.
Do not overmix after adding wet ingredients to rice to prevent deflating aeration from eggs.
Do not exceed 25 minutes baking to avoid dry, rubbery texture throughout.

FAQ
Can I use leftover white or brown rice?
Yes, both work equally well. Ensure rice is cooled before mixing. Day-old rice separates better during stirring, preventing clumping in the final dish.
What if my souffle falls after removing from oven?
Some settling is normal as it cools. If it collapses immediately, the custard was underbaked; bake longer next time. Slight deflation does not affect flavor or texture significantly.
How long can I keep leftovers and can I freeze it?
Refrigerate covered for 2 days. Freezing is not recommended as custard-based souffles become grainy and separate upon thawing. Best eaten fresh or within one day.
