Preheat oven to 375°F. Grease an 8x8 or 9x9 baking dish.
Add rice straight into the dish — no rinsing needed.
Pour in the beef consommé, French onion soup, and both cans of mushrooms with the liquid.
Melt butter and pour it evenly over the top. Don’t overmix — a gentle “swish” or light zhuzh with a spoon is all it needs.
Top with grated Locatelli Pecorino Romano cheese.
Cover tightly with foil and bake 1 hour.
Check to see if there’s excess liquid. If so, bake uncovered 8–10 more minutes.
Fluff with a fork and serve!
