My French Onion Ground Beef and Rice Casserole started as a way to use up leftover ingredients one night but quickly became our family's most requested comfort meal. The combination of sweet caramelized onions savory beef and gooey Swiss cheese creates something truly magical. When that aroma fills the kitchen my kids come running and my husband always claims the corner piece with extra crispy onions on top.

Make It Your Own
Sometimes I toss in mushrooms or peas for extra veggies. If you're feeling adventurous try adding a dash of hot sauce or switch up the cheese we love using Gruyère when we're feeling fancy. For a healthier twist brown rice works great just give it a little extra cooking time.
Plan Ahead
This casserole freezes beautifully just wait to add those crispy onions until you're ready to serve. You can also prep everything the night before pop it in the fridge and bake it when you get home from work. Leftovers taste even better the next day after all those flavors have had time to meld together.
