Why You’ll Love Licurdia (Calabrian Onion Soup) Recipe
Licurdia is proof that humble ingredients can create an incredibly satisfying dish. Slowly cooking the onions develops their natural sweetness, while Calabrian chili peppers provide a pleasant warmth that keeps the soup from becoming overly sweet.
Grated potatoes are particularly useful in this recipe. They help give the broth more body without turning it into a heavy cream-based soup. Fennel seeds add a subtle aromatic note that pairs beautifully with both the onions and chili.
The finishing touch makes this soup especially comforting. A slice of Italian bread floats on each serving and is covered with grated Asiago before going under the broiler. The bread absorbs some of the flavorful broth while the cheese develops a bubbling, golden crust.
It is also easy to adapt. Olive oil can replace the traditional lard, the amount of chili can be adjusted, and different flavorful melting cheeses can be used depending on what you have available.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
- 3 lbs sweet onions, thinly sliced
- 2 tbsp lard, or olive oil as a substitute
- 1/2 lb gold potatoes, peeled and grated
- 1 tbsp Calabrian chili peppers in oil
- 1 tsp fennel seeds
- 1 tsp kosher salt, divided
- 1 tbsp all-purpose flour
- 5 cups low-sodium chicken stock
- 1/2 loaf Italian bread or baguette
- 1 cup Asiago cheese, grated
Directions
1. Prepare the Onions and Potatoes
Thinly slice the sweet onions into approximately 1/4-inch slices. Keeping the slices fairly uniform allows them to soften evenly without completely disappearing into the soup.
Wash and peel the gold potatoes, then grate them. Place the grated potatoes in cheesecloth or a clean kitchen towel and squeeze firmly to remove as much excess liquid as possible. Removing this moisture helps the vegetables sauté and caramelize instead of steaming.
2. Sweat the Onions
Heat the lard or olive oil in a large Dutch oven over medium-low heat. Once the fat is hot, add the sliced onions and 1/2 teaspoon of kosher salt.
Cover the pot and cook for about 15 minutes, stirring occasionally. The onions should become tender and noticeably decrease in volume, but they should not develop much brown color at this stage.
3. Add the Seasonings
Increase the heat to medium. Add the remaining 1/2 teaspoon of salt, fennel seeds, and Calabrian chili peppers.
Stir and cook for about 30 seconds, just until the fennel becomes fragrant. Add the squeezed grated potatoes and stir until they are evenly distributed throughout the onions.
4. Sauté the Vegetables
Sprinkle the flour evenly over the onion and potato mixture. Stir thoroughly until no visible dry flour remains.
Continue cooking over medium heat for 15 to 20 minutes. Stir occasionally and scrape the bottom of the Dutch oven as necessary to prevent sticking.
During this stage, the onions should begin to develop some golden caramelization, creating a richer flavor for the finished soup.
5. Simmer the Soup
Pour the chicken stock into the pot and increase the heat to medium-high.
As the stock heats, scrape the bottom of the Dutch oven to loosen any flavorful browned bits. Bring the soup to a gentle simmer, then cook for approximately 20 minutes.
The onions should become very tender, while the grated potatoes and flour give the broth additional body.
6. Add the Bread and Cheese
Turn on the oven broiler.
Carefully ladle the soup into oven-safe bowls and arrange the bowls on a sturdy sheet pan. Place a slice of Italian bread or baguette on top of each serving.
Sprinkle the bread generously with grated Asiago cheese.
7. Broil and Serve
Place the sheet pan approximately 6 inches beneath the broiler. Broil for 3 to 4 minutes, watching carefully, until the Asiago is melted, bubbling, and golden brown.
Carefully remove the bowls from the oven. Allow them to cool briefly before serving, as both the bowls and soup will be extremely hot.
Servings and timing

- Servings: 6
The cooking time includes sweating and caramelizing the onions, simmering the soup, and broiling the bread and cheese topping.
Variations
Vegetarian Licurdia
Replace the chicken stock with a flavorful low-sodium vegetable stock and use olive oil instead of lard. The soup will retain its characteristic sweet onion flavor while becoming completely meat-free.
Milder Version
Calabrian chili peppers have a distinctive fruity heat. For a gentler soup, reduce the amount to 1 or 2 teaspoons. You can always add additional chili when serving.
Extra-Spicy Licurdia
For more heat, increase the Calabrian chili peppers or add a small spoonful of the oil from the chili jar. Add gradually so the spice does not overpower the sweetness of the onions.
Different Cheese
Asiago contributes a salty, nutty finish, but other flavorful cheeses can work well. Pecorino Romano provides a sharper taste, while provolone or fontina creates an especially melty topping.
Vegetable Additions
For a heartier variation, add finely chopped celery, carrots, or leafy greens. Keep the amount moderate so sweet onions remain the dominant flavor.
Extra-Crispy Bread
Lightly toast the Italian bread before placing it on the soup. This creates a firmer base that takes longer to absorb the broth and provides additional texture beneath the melted cheese.
Storage/Reheating
Allow leftover Licurdia to cool before transferring it to an airtight container. For the best results, store the soup separately from the bread and cheese topping.
Refrigerated soup can be kept for approximately 3 to 4 days. When ready to eat, reheat it gently in a saucepan over medium-low heat, stirring occasionally, until thoroughly heated.
Individual portions can also be reheated in the microwave. Heat in short intervals and stir between intervals so the soup warms evenly.
For the best texture, add fresh bread and grated Asiago after reheating the soup. Transfer the hot soup to an oven-safe bowl, top it with bread and cheese, and broil until the cheese is melted and golden.
The soup base can also be frozen without the bread and cheese. Transfer cooled soup to a freezer-safe container, leaving a little room for expansion, and freeze for up to 2 to 3 months. Thaw overnight in the refrigerator before reheating.
FAQs
What is Licurdia?
Licurdia is a traditional rustic soup associated with Calabria in southern Italy. Onions are the defining ingredient, creating a naturally sweet and savory base that can be complemented by potatoes, bread, cheese, and other simple ingredients.
What type of onions are best for Licurdia?
Sweet onions work particularly well because their natural sugars develop beautifully during slow cooking. Other yellow or mild onions can also be used, although the final flavor may be slightly sharper.
Why shouldn’t I brown the onions during the first cooking stage?
The initial covered cooking period is designed to sweat and soften the onions. Browning them too quickly can create deeper roasted flavors before they have fully softened. Caramelization happens later, after the potatoes and flour are added.
Why do I need to squeeze the liquid from the grated potatoes?
Removing excess moisture helps the potatoes sauté rather than steam. It also encourages better caramelization when the potatoes are cooked with the onions.
Can I use olive oil instead of lard?
Yes. Olive oil is an excellent substitute and produces a flavorful soup. Lard provides additional richness and a more traditional rustic character, but the recipe works well with either option.
How spicy is this Calabrian onion soup?
One tablespoon of Calabrian chili peppers gives the soup noticeable warmth without necessarily making it overwhelmingly spicy. Heat levels vary between brands and preparations, so you can reduce or increase the amount according to preference.
What can I substitute for Asiago cheese?
Pecorino Romano, Parmesan, provolone, fontina, or a combination of flavorful Italian cheeses can work. For the broiled topping, a cheese that melts nicely is particularly useful.
Can I make Licurdia ahead of time?
Yes. Prepare the soup through the simmering stage and refrigerate it without adding the bread or cheese. Reheat the soup when needed, then add fresh bread and Asiago and broil immediately before serving.
Can I freeze Licurdia?
Yes. Freeze the onion soup base without the bread and cheese for the best results. Once thawed and reheated, add fresh bread and grated cheese before broiling and serving.
What should I serve with Licurdia?
Because Licurdia already includes bread, potatoes, onions, and cheese, it can easily stand alone as a satisfying meal. For a larger dinner, pair it with a simple green salad, roasted vegetables, or a light Italian-inspired main course.
Conclusion
Licurdia is a wonderful example of rustic Calabrian cooking, turning everyday ingredients into a warming and flavorful soup. Slowly softened sweet onions form the heart of the dish, while grated potatoes add body, fennel seeds provide aromatic depth, and Calabrian chili peppers introduce a distinctive touch of heat.
Finishing each serving with Italian bread and bubbling golden Asiago makes the soup particularly satisfying. Whether served as a cozy main course or as the beginning of an Italian-inspired dinner, this Calabrian onion soup delivers plenty of character from a remarkably simple collection of ingredients.
