Step‑by‑Step Instructions for French Onion Ground Beef and Rice Casserole
Step 1: Cook Ground Beef
In a large skillet over medium heat, brown the ground beef for about 6-8 minutes, breaking it apart as it cooks until it’s no longer pink. Once browned, drain excess grease, and set the cooked beef aside. You want tender, juicy beef for your French Onion Ground Beef and Rice Casserole to ensure maximum flavor.
Step 2: Sauté Onion
In the same skillet, add a drizzle of oil or a pat of butter and sauté the chopped onion over medium heat for 5-7 minutes, stirring occasionally. Cook until the onions are soft and golden brown, releasing their natural sweetness. This step enhances the flavor profile of your casserole beautifully.
Step 3: Mix Ingredients
In a large mixing bowl, combine the cooked ground beef, sautéed onion, rice, French onion soup, garlic powder, salt, and pepper. Stir well for 2-3 minutes until the mixture is completely combined and all ingredients are well integrated. This creates the flavorful filling for your French Onion Ground Beef and Rice Casserole.
Step 4: Assemble Casserole
Preheat your oven to 350°F (175°C). Grease a 9×13-inch casserole dish, then transfer the beef and rice mixture into the dish, spreading it evenly. Sprinkle a generous layer of shredded cheese on top, allowing it to melt beautifully as it bakes. This cheesy topping adds that comforting element everyone loves.
Step 5: Bake
Cover the casserole with aluminum foil and bake in the preheated oven for 30 minutes. After 30 minutes, remove the foil and return the dish to the oven, baking for an additional 10-15 minutes, until the cheese is melted, bubbly, and beautifully golden. You’ll see the edges getting nice and crispy!
Step 6: Serve
Let the French Onion Ground Beef and Rice Casserole rest for about 5 minutes after baking. This helps the dish set a bit, making it easier to slice. Serve it warm and enjoy the comforting flavors with your family, cherishing every hearty bite.

French Onion Ground Beef and Rice Casserole Recipe FAQs
How do I choose the right ground beef for this casserole?
Absolutely! When selecting ground beef, look for an 80/20 ratio, meaning 80% lean meat to 20% fat. This balance will ensure your casserole is juicy and flavorful without being greasy. If you’re seeking a healthier alternative, ground turkey is a fantastic substitute that still offers a delicious taste.
How should I store leftover casserole?
Simply transfer any uneaten portions into an airtight container and place in the fridge. It will stay fresh for about 3 days. For longer storage, consider freezing it as mentioned; just make sure to wrap it tightly to prevent freezer burn.
Can I freeze the French Onion Ground Beef and Rice Casserole?
Definitely! To freeze, first cool the casserole completely. Then, wrap it tightly in plastic wrap, followed by aluminum foil. It can be stored in the freezer for up to 1 month. When ready to eat, thaw it overnight in the fridge, and then bake at 350°F (175°C) for about 20-25 minutes until fully heated.
What should I do if my casserole is too dry?
If you find your casserole dry, consider adding more French onion soup or a splash of beef broth before baking. It can also help to cover it with foil during baking to lock in moisture. I often suggest checking for balance in flavors by ensuring that the beef is well-browned and the onions are caramelized, as these steps deepen the dish’s richness.
Are there any dietary considerations I should be aware of?
Absolutely! This casserole is versatile and can cater to various dietary needs. For a gluten-free version, opt for gluten-free rice and soups. If you or anyone at your table has lactose intolerance, dairy-free cheese can replace regular cheese. Also, keep in mind any allergies to ingredients like onion or garlic; you can omit or substitute those as needed.
How long can I keep the casserole in the fridge before eating?
Leftovers are safe to store in the fridge for up to 3 days. To make the most of it, consider dividing your casserole into smaller portions for quick, easy reheating during the week!
