Ingredients

  • 1 lb. ground beef
  • 1 (1 3/8 oz.) package dry onion soup mix
  • 1 (10 3/4 oz.) can condensed cream of mushroom soup
  • 2 1/2 cups boiling water
  • 1/2 cup sliced green onion tops

Instructions

  1. Brown the ground beef in a skillet; drain off excess fat.
  2. Put the browned beef in a greased 2-quart casserole dish.
  3. Sprinkle with rice and dry onion soup mix.
  4. Combine the condensed cream of mushroom soup with boiling water.
  5. Pour the mushroom soup mixture over the rice in the casserole.
  6. Bake uncovered at 350°F for 1 hour or until the rice is tender.
  7. Sprinkle with sliced green onion tops before serving.

Tips & Substitutions

For best results, use lean ground beef to reduce excess fat. You can substitute the cream of mushroom soup with cream of chicken soup if desired. If you want to add more flavor, consider mixing in some sautéed mushrooms or bell peppers. For a vegetarian version, replace the beef with lentils or a meat substitute, and use vegetable broth instead of water.

Serving Suggestions

This casserole pairs beautifully with a fresh green salad or steamed vegetables for a complete meal. You could also serve it alongside crusty bread to soak up the creamy sauce. For a comforting twist, consider serving it with a side of garlic bread, reminiscent of American recipes like Banquet Spaghetti Supper.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the casserole in the oven at 350°F until warmed through, about 20-25 minutes. You can also microwave individual portions on medium power for 2-3 minutes, stirring halfway through for even heating.

Frequently Asked Questions

Can I use brown rice instead of white rice in this casserole?

You can use brown rice, but keep in mind that it requires a longer cooking time. Adjust the baking time to about 1.5 hours, and add an additional cup of boiling water to ensure it cooks properly.

Is it possible to prepare this casserole in advance?

Yes, you can assemble the casserole a day ahead. Just cover it with foil and refrigerate. When ready to bake, allow it to come to room temperature before placing it in the oven, and extend the baking time by about 10-15 minutes if it’s still cold.

What can I add to enhance the flavor of this dish?

Consider adding a teaspoon of garlic powder or Worcestershire sauce to the beef while browning for extra depth of flavor. Fresh herbs, such as thyme or parsley, can also brighten the dish when sprinkled on top before serving.
