Tools Needed

Cooking Instructions
Step 1: Preheat oven
Preheat oven to 375°F (190°C). Lightly grease a 9×13” baking dish.
Step 2: Cook the beef
In a large skillet, heat olive oil over medium heat. Add chopped onion and cook until soft and golden, about 5–6 minutes. Add ground beef and garlic, cooking until browned. Drain excess grease.
Step 3: Mix it all together
In a mixing bowl, stir together cream of mushroom soup, French onion soup, beef broth, Worcestershire sauce, and uncooked rice. Season with salt and pepper.
Step 4: Assemble the casserole
Spread the cooked beef and onion mixture evenly in the baking dish. Pour the rice and soup mixture over the beef. Stir gently to combine.
Step 5: Bake covered
Cover tightly with foil and bake for 45 minutes.
Step 6: Optional cheesy topping
If using cheese, uncover the casserole, sprinkle cheddar on top, and bake an additional 10–15 minutes until the cheese is melted and bubbly and rice is fully tender.
Step 7: Serve
Let the casserole rest for 5 minutes before serving. Garnish with parsley or crispy fried onions if desired.

FAQs
1. Can I use brown rice instead of white?
It’s possible, but it takes longer and may require extra liquid. Parboil it first if you want to try!
2. Can I use ground turkey or chicken instead of beef?
Yes! Just season it well since turkey and chicken are milder in flavor.
3. Can I prep this in advance?
Absolutely—assemble it earlier in the day, cover, and refrigerate. Just add a few minutes to the baking time.
4. Is the cheese necessary?
Not at all—it adds richness but the casserole is still flavorful without it.
Tips & Tricks
– Sauté the onions until lightly caramelized for extra flavor
– Add a pinch of dried thyme or rosemary to the mix for an herby twist
– Stir in a handful of frozen peas or corn before baking to up the veggies
– Swap cheddar for Swiss or provolone for a different flavor profile
– For more texture, top with crispy fried onions just before serving
Recipe Variations
1. Tex-Mex Twist
Add taco seasoning to the beef, swap French onion soup for salsa, and top with pepper jack cheese.
2. Mushroom Lover’s Version
Add a cup of sliced mushrooms to the onions as they cook and use Swiss cheese on top.
3. Veggie Boost
Mix in spinach, zucchini, or bell peppers before baking.
4. Cheeseburger Casserole Style
Add mustard, a bit of ketchup, and diced pickles to the beef mixture for a fun twist.
