An update to today's Yummy Recipe Monday post: For the French onion casserole cook the rice ahead of time, either in a rice cooker or on the stove. Don't put the rice uncooked into the casserole then bake it. Rice will be a little crunchy if you don't cook it before putting it in the casserole.
My family and I tried this recipe. Except we didn't cook the rice before putting it in the casserole. We did cook the ground beef, though, just to be safe, before we added it to the casserole.
So cook the rice and the ground beef. Then follow the steps in the recipe.
