About Sopa Castellana
Sopa Castellana, also known as Castilian garlic soup, is a classic Spanish dish that is especially treasured across many regions of the country. Its charm lies in its sheer simplicity and its bold, savoury flavour. The hallmarks of the soup are garlic, egg and day-old bread, brought together in a single fragrant pot. More than anything, it is a clever and delicious way to make the most of leftover bread that might otherwise go to waste.
Ingredients (serves 1–2)
- 4 cloves of garlic
- 3–4 slices of stale bread
- 50g Serrano ham
- 1 teaspoon paprika (sweet or hot)
- 2 eggs
- 500ml chicken stock
- 3 tablespoons olive oil
- Salt and pepper, to taste
Shopping for the ingredients
Making Sopa Castellana calls for just a few ingredients, so it pays to choose good-quality ones. When buying the Serrano ham, look for a well-aged cut with a deep, savoury flavour. The garlic should be fresh so it can release its full aroma in the pan. With the paprika, you can take your pick between sweet or hot, depending on how much warmth you want in the finished soup.
Preparing the dish
Begin your preparation by peeling the garlic and slicing it thinly. Cut the day-old bread into small cubes, and chop the Serrano ham into little pieces as well. Have everything laid out and ready to hand before you start cooking, so the soup comes together quickly and smoothly once the pan is hot.
Step-by-step instructions
- Heat the olive oil in a large pot and fry the garlic until it turns golden brown.
- Add the cubes of bread and toast them in the oil until crisp.
- Stir in the Serrano ham and the paprika, frying everything briefly together.
- Pour in the chicken stock and let the soup simmer for around 10 minutes.
- Crack the eggs into the soup and stir gently so they cook into soft “flakes”.
- Season with salt and pepper to taste and serve piping hot.
Gluten-free / lactose-free version
To enjoy Sopa Castellana gluten-free, simply swap the stale bread for a gluten-free loaf, widely available in supermarkets and health-food shops. Just double-check that all the other ingredients are gluten-free too. Because the traditional recipe contains no dairy at all, it is naturally lactose-free, making it an easy choice for anyone avoiding milk products.
Tips for vegans and vegetarians
For a vegetarian version of Sopa Castellana, simply leave out the Serrano ham. In that case it is worth adding a little extra spice or switching to a flavourful vegetable stock to give the soup more depth. A vegan version is just as achievable: replace the eggs with a plant-based alternative and use a vegan stock so nothing of the soup’s hearty character is lost.
More tips and tricks
Sopa Castellana lends itself beautifully to variation. Try adding extra spices such as cumin or thyme to give the soup a new flavour dimension. If you prefer a thicker, more substantial bowl, simmer one or two potatoes cut into small pieces along with everything else — they lend the soup a lovely, comforting body.
Adapting the recipe to your taste
The intensity of the spices can be tuned entirely to your liking. If you enjoy a bit of fire, reach for hot paprika or even a small chilli. You can also bump up the garlic for a more pronounced aroma. Beyond that, feel free to explore regional twists — for instance, by working in local Spanish sausages, much like the smoky Chorizo a la Parrilla.
Ingredient substitutions
If you cannot get hold of Serrano ham, prosciutto or Parma ham make excellent stand-ins. The paprika can be replaced with smoked paprika, which adds a lovely smoky note to the soup. As an alternative to chicken stock, a robust vegetable stock works well and makes the dish suitable for vegetarians — a touch you will also find in Espinacas con Garbanzos.
Drink pairing ideas
Sopa Castellana is wonderful with a glass of Spanish red wine. In Spain the soup is often served with a Rioja or a Tempranillo, both prized for their fruitiness and gentle spice. Alternatively, a dry white wine or a refreshing beer pairs very nicely with this hearty dish.
Serving and presentation ideas
Serve the Sopa Castellana in rustic earthenware bowls to highlight the soup’s traditional character. A fresh sprig of parsley or a few drops of olive oil make an attractive garnish. Set out some fresh, crusty bread for dipping and bring the soup to the table while it is still piping hot.
A bit of history
Sopa Castellana comes from the region of Castile in Spain and is a classic example of simple yet delicious peasant cooking. It originally served as a filling meal for poorer households, who turned humble ingredients like stale bread and garlic into something nourishing and satisfying. Today it is a firm fixture of Spanish cuisine, enjoyed as a starter or a light evening meal.
