Ingredients

  • 4 small onions, thinly sliced
  • 2 Tbsp. margarine
  • 2 Tbsp. flour
  • 2 (10 1/2 oz.) cans chicken broth
  • 1 cup half and half

Instructions

  1. Cook sliced onions in margarine for 3 to 4 minutes until softened.
  2. Add flour and cook for a few minutes, stirring constantly.
  3. Add chicken broth, half and half, salt, and pepper to the mixture.
  4. Simmer on low heat until the soup thickens, stirring often.

Tips & Substitutions

For a richer flavor, try using butter instead of margarine. If you prefer a thicker soup, blend a portion after simmering and return it to the pot. For a vegetarian version, substitute vegetable broth for chicken broth. You can also add a splash of white wine for extra depth. If you have fresh herbs like thyme or parsley, they can elevate the dish significantly.

Serving Suggestions

Serve this creamy onion soup with crusty bread or a side salad for a complete meal. It pairs beautifully with Chicken Oporto from the Good Housekeeping Illustrated Cookbook for a heartier dinner. For a twist, try topping each bowl with croutons or a sprinkle of grated cheese just before serving.

Storage & Reheating

Let the soup cool completely before transferring it to an airtight container. It can be stored in the refrigerator for up to 3 days. When reheating, add a splash of broth or half and half to restore creaminess and heat gently on the stove over low heat, stirring occasionally to prevent sticking.
