Ingredients

½ teaspoon ground black pepper
-
1 teaspoon salt (adjust to taste)
-
1 pinch of nutmeg (optional but traditional in some recipes)
Optional Additions (Choose Your Variation):
-
1 egg (beaten or poached into the soup)
-
½ cup shredded cheese (Parmesan, Emmentaler, or Gruyère)
-
Chopped parsley or chives for garnish
-
A dash of vinegar or lemon juice for acidity

Croutons or toasted bread for topping

-
Optional: immersion blender (if you want a smoother texture)
Step-by-Step Instructions
Step 1: Create the Roux
-
In a medium saucepan over medium heat, melt the butter (or heat the oil/lard).
-
Add the flour and stir constantly to combine. The mixture should look like a thick paste.
-
Continue stirring and cooking the roux for 5–8 minutes, or until it turns a golden brown color and gives off a nutty aroma. Be careful not to let it burn. This step builds depth of flavor.
Step 2: Add Aromatics (Optional)
-
If using onion and garlic, stir them into the roux and cook for another 2–3 minutes until softened.
-
Stir constantly so that the flour doesn’t burn and everything blends smoothly.
Step 3: Add the Liquid
-
Slowly pour in the broth a little at a time, whisking constantly to prevent lumps.
-
Once all the broth is added, bring the mixture to a gentle boil, then reduce heat to low.
-
Simmer for 10–15 minutes, stirring occasionally, until the soup thickens slightly and takes on a creamy consistency.
Step 4: Season and Customize
-
Add salt, pepper, and a pinch of nutmeg (if using).
-
If you like a richer soup, beat one egg and slowly drizzle it into the hot soup while stirring constantly. This will create lovely egg ribbons.
-
Alternatively, you can crack an egg directly into the simmering soup and let it poach for 3–4 minutes.
-
Stir in shredded cheese if using, allowing it to melt and add depth.
Step 5: Serve
-
Ladle the hot soup into bowls.
-
Garnish with fresh chopped parsley, chives, or green onions.
-
Serve with toasted bread, croutons, or even a hard-boiled egg on top for added protein.
Tips for Success
-
Use good broth: Since the soup is so simple, the quality of your broth makes a big difference. Homemade or low-sodium store-bought broths are ideal.
-
Control the heat: Don’t rush the roux step. A slow, gentle browning brings out the flavor.
-
Make it creamy: Add a splash of milk or cream near the end if you prefer a richer, velvety texture.
Variations Around the World
Swiss Flour Soup (Basler Mehlsuppe):
Traditionally eaten during Carnival in Basel, this version uses darkly browned flour, onion, beef broth, and Gruyère cheese, simmered slowly to create a savory, rich dish with deep flavor.
Hungarian Flour Soup:
Flavored with paprika, garlic, and sometimes sour cream, this version may include egg noodles or chopped vegetables for a heartier meal.
Italian Farinata Soup:
In Tuscany, flour-based soups are enriched with olive oil, white beans, and leafy greens like kale or chard.
Make-Ahead & Storage Instructions
-
Make Ahead: Flour soup can be made in advance and reheated on the stove. Stir frequently while reheating to maintain smooth texture.
-
Refrigerator: Store in an airtight container for up to 3 days.
-
Freezer: Not ideal for freezing due to the roux base, which can separate upon thawing.
