Ingredients

  • 3 medium onions
  • 1/4 cup butter or margarine
  • 4 cups beef broth
  • 1 teaspoon Worcestershire sauce
  • 1 teaspoon salt
  • 1 teaspoon soy sauce
  • 1/2 teaspoon paprika
  • grated Parmesan cheese

Instructions

  1. Slice onions thinly.
  2. Combine onions and butter in a 3-quart microwaveproof casserole.
  3. Cover and cook on High for 10 to 12 minutes, stirring once, until onions are transparent.
  4. Stir in beef broth, Worcestershire sauce, salt, soy sauce, paprika, and grated Parmesan cheese.
  5. Cook on High for an additional 10 to 11 minutes, or until hot.
  6. Serve in bowls with cheese sprinkled on top.

Tips & Substitutions

For a deeper flavor, consider adding a splash of red wine or a bay leaf while cooking the onions. If you're short on time, pre-sliced onions are a great alternative. You can also use vegetable broth for a vegetarian version. Adjust the Worcestershire sauce and soy sauce to your taste for a more pronounced umami flavor, similar to what's found in other beef recipes.

Serving Suggestions

This hearty soup pairs beautifully with a crusty bread or a side salad for a complete meal. Top each bowl with additional grated Parmesan cheese for extra richness. For a twist, serve it alongside a sandwich, like a classic grilled cheese, or even with Beef And Cheese Pinwheels for a delightful combination.

Storage & Reheating

Store leftover soup in an airtight container in the refrigerator for up to 3 days. To reheat, simply transfer the soup to a microwave-safe bowl and heat on High for 1-2 minutes, stirring occasionally, until hot. You can also reheat it on the stovetop over medium heat until warmed through.
