Step‑by‑Step Instructions for Ground Beef and Rice Casserole
Step 1: Preheat and Prepare the Dish
Start by preheating your oven to 425°F (220°C). While the oven warms up, grab a 9×13 inch baking dish and give it a light spray with cooking spray to prevent sticking. This foundational step ensures your casserole bakes evenly, creating that perfect golden crust.
Step 2: Brown the Ground Beef
In a large skillet over medium heat, add the ground beef. Cook it for about 7-10 minutes while breaking it apart with a spatula, until it’s fully browned and crumbly. Season the mixture with garlic salt to enhance the flavor. Once cooked, drain any excess fat for a healthier, lighter casserole.
Step 3: Combine the Ingredients
In the prepared baking dish, combine the uncooked long grain white rice, browned beef, beef consume, French onion soup, and measured water. Stir everything together thoroughly until it’s well mixed, creating a base that ensures each bite of your Ground Beef and Rice Casserole is packed with flavor.
Step 4: Add Butter for Creaminess
Slice butter into thin pieces and distribute them evenly over the top of your casserole mixture. This step will add necessary creaminess and flavor as it melts during baking, enriching the dish with a velvety texture that everyone will love.
Step 5: Cover and Bake
Cover your baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 30 minutes to allow the flavors to meld and the rice to absorb the liquids. This covered baking creates steam, helping the rice cook perfectly.
Step 6: Uncover and Bake Until Golden
After 30 minutes, carefully remove the foil to let the casserole brown. Continue baking for an additional 30 minutes or until the top is bubbly and golden brown. Watch for that enticing color change, which indicates that your Ground Beef and Rice Casserole is nearing completion.
Step 7: Fluff and Serve
Once baked, remove the casserole from the oven and let it sit for a few minutes. Fluff the rice gently with a fork to separate the grains and mix in any sauce that settled at the bottom. Serve the dish hot, delighting in its rich flavors and hearty texture that’s perfect for cozy dinners.

Storage Tips for Ground Beef and Rice Casserole
Fridge: Store leftover casserole in an airtight container for up to 3 days to maintain freshness.
Freezer: For longer storage, freeze the casserole in a properly sealed container for up to 2 months. Allow it to cool completely before freezing.
Reheating: To reheat, thaw the casserole in the refrigerator overnight, and warm it in the oven at 350°F until heated through, preserving its comforting texture.
Avoiding Freezer Burn: Wrap the dish tightly in plastic wrap or aluminum foil before freezing to prevent freezer burn and keep the flavors intact in your Ground Beef and Rice Casserole.
Expert Tips for Ground Beef and Rice Casserole
Browning Matters: Make sure to brown the ground beef well to enhance the flavor. Undercooked meat can lead to a bland casserole.
Liquid Precision: Measure your water accurately! Too much liquid makes mushy rice, while too little leaves it crunchy.

Herb Infusion: Consider adding dried herbs like thyme or parsley for an extra layer of flavor in your Ground Beef and Rice Casserole.
Leftover Love: Store leftovers in an airtight container for up to 3 days. Reheat gently to maintain its comforting texture and flavors.
