- To keep the soup vegetarian, substitute the chicken broth with vegetable broth.
- If you want a lighter version, use whole milk instead of half-and-half, but note the soup will be less creamy.
- For extra flavor, sauté a clove of minced garlic with the onions.
- This soup freezes well; reheat gently on the stove to maintain its creamy texture.
- Adjust the thickness by adding more broth if too thick, or simmer longer if too thin.
