Italian Onion Stew (Cipollata) Recipe

Italian onion stew is a rustic, savory dish of slowly softened onions simmered with tomatoes, broth, and creamy white beans. Often called cipollata, the name covers different onion-centered dishes across Italy; this hearty version makes a satisfying one-pot meal with crusty bread or polenta.

Ingredients

3 lb (1.36 kg) yellow onions, peeled and thinly sliced
2 tbsp (30 ml) extra-virgin olive oil
1 medium carrot (about 75 g), finely diced
1 celery rib (about 50 g), finely diced
3 garlic cloves (about 9 g), minced
2 tbsp (32 g) tomato paste
1 can chopped tomatoes, 14.5 oz (411 g)
4 cups (950 ml) vegetable broth, preferably low-sodium
2 cans cannellini beans, 15 oz (425 g) each, drained and rinsed
1 bay leaf
1 tsp (1 g) dried oregano
¼ tsp (0.5 g) red pepper flakes, optional
1 tsp (5 g) fine sea salt, plus more to taste
¼ tsp (0.5 g) freshly ground black pepper, plus more to taste
2 tsp (10 ml) red wine vinegar
2 tbsp (8 g) chopped fresh flat-leaf parsley

Instructions

Prepare the vegetables. Peel the onions, halve them from root to tip, and slice them thinly. Dice the carrot and celery, mince the garlic, and drain and rinse the beans. Slicing the onions evenly helps them soften at the same rate. This preparation takes about 20 minutes; keep the sliced onions in a large bowl until the pot is ready.
Soften the onions. Heat the olive oil in a heavy Dutch oven or large, thick-bottomed pot over medium-low heat. Add the onions and salt, then stir to coat. Cook uncovered for 25 minutes, stirring every few minutes and scraping the bottom as needed. The onions should become very soft and turn pale gold in places, but they should not scorch or become crisp. If the pot starts to look dry or the onions catch, lower the heat and add a tablespoon of water.
Add the aromatic vegetables. Stir in the carrot and celery and cook for 5 minutes, stirring occasionally, until they begin to soften. Add the garlic and cook for 1 minute, just until fragrant. Keep the heat moderate; browned or bitter garlic can overwhelm the sweetness of the onions.
Concentrate the tomato. Add the tomato paste, oregano, and red pepper flakes, if using. Stir for about 1 minute to coat the vegetables, then pour in the chopped tomatoes. Cook for 3 more minutes, stirring and loosening any browned bits from the bottom of the pot. The tomato paste should look darker and smell savory rather than raw.
Simmer the stew base. Pour in the vegetable broth and add the bay leaf and black pepper. Stir well, bring the liquid to a gentle simmer, then cook uncovered for 10 minutes. A steady, gentle simmer gives the onions time to flavor the broth without breaking them down completely. If the liquid boils hard, reduce the heat.
Add the beans. Stir in the drained cannellini beans and simmer gently for 10 minutes, stirring once or twice. Taste a bean and check that it is hot and tender. For a thicker, more cohesive stew, press a few beans against the side of the pot with the back of a spoon and stir them in; leave the rest whole for texture.
Finish and serve. Remove the bay leaf. Stir in the red wine vinegar and parsley, then taste and adjust the salt, pepper, or vinegar. The vinegar should brighten the stew rather than make it taste sour. Let it stand for a few minutes off the heat if you want a slightly thicker consistency, then ladle into warm bowls.

Tips

Give the onions time. The long, gentle first cook is the foundation of the dish. Avoid turning the heat up to hurry it along: onions that brown too quickly can taste sharp and leave dark bits on the pot. Stir more often toward the end of the 25 minutes, when their released moisture has mostly cooked away.
Adjust the liquid to your preference. For a spoonable stew, use the listed 4 cups of broth. If you prefer it more like a thick soup, add ½ cup (120 ml) extra broth. If it seems too thin, simmer it uncovered for a few additional minutes before serving, or mash a few more beans into the liquid.
Watch the salt in the broth. Low-sodium broth gives you control over seasoning, especially because canned beans and tomatoes vary in saltiness. If using regular broth, begin with less added salt and taste again after the beans have simmered.
Make it without beans if you like. The beans make this version a filling main course, but they are not essential to every Italian onion-stew variation. Omit them and use 3 cups (710 ml) broth for a more onion-forward bowl, or replace them with 1½ cups (240 g) cooked chickpeas for a firmer, nuttier bite.

Serving Suggestions

Serve the stew hot in shallow bowls with toasted country bread, grilled sourdough, or another sturdy loaf for soaking up the tomato and onion broth. A drizzle of good olive oil and a little extra chopped parsley make simple finishing touches. Grated Parmigiano-Reggiano is a welcome optional garnish, though the stew is also flavorful without cheese.

For a larger Italian-inspired meal, pair it with a crisp green salad dressed with lemon or red wine vinegar. Soft polenta is another good base: spoon the stew over it just before serving so the polenta can catch the broth. If serving it as a first course, offer smaller portions and follow with roasted vegetables or a simple pasta dish.

Variations

Use different onions. Yellow onions give the stew a balanced, savory sweetness. White onions make the flavor a little sharper, while red onions bring a deeper color and a sweeter finish. A mix works well, though cooking time may vary slightly depending on the size and moisture of the onions.

Add greens. Stir in 3 packed cups (about 90 g) of chopped spinach during the final 2 minutes, or add chopped kale during the last 8 to 10 minutes so it has time to soften. This changes the texture and makes the pot greener, but does not require a different method.

Make it richer or more rustic. Replace 1 cup (240 ml) of the broth with dry white wine, letting the wine simmer for a few minutes before adding the remaining broth; the result is more aromatic and slightly sharper. For a smoky note, add ½ tsp (about 1 g) smoked paprika, understanding that it is a modern variation rather than a traditional requirement.

Try an egg-topped serving. Some onion-centered Italian dishes are served with eggs, but this recipe does not need them. For an optional variation, poach eggs separately and place one on each bowl just before serving. Cook egg dishes to 160°F (71°C), the USDA FSIS safe minimum internal temperature, checked with a food thermometer when appropriate.

Storage and Reheating

Cool the stew promptly and refrigerate it within 2 hours of cooking in a covered, shallow container. It keeps for 3 to 4 days in the refrigerator. The onions and beans absorb broth as they sit, so the stew may be thicker the next day; stir in a splash of water or broth when reheating.

Reheat only the portion you plan to eat in a saucepan over medium-low heat, stirring occasionally until it is steaming throughout and reaches 165°F (74°C), the USDA FSIS temperature for reheated leftovers. You can also microwave an individual serving in a covered, microwave-safe bowl, stirring halfway through and checking the temperature in more than one spot. Freeze cooled portions in airtight, freezer-safe containers for up to 3 months for best quality. Thaw overnight in the refrigerator and reheat to 165°F (74°C); the beans may soften a little after freezing, but the flavor remains suitable for a quick meal.

Frequently Asked Questions

What does cipollata mean?
Cipollata is an Italian word associated with onion-based dishes, and recipes vary by region and household. It can refer to preparations with different ingredients and textures, so this tomato, bean, and broth version is best understood as a hearty cipollata-style stew, not the sole traditional formula.

Can I make this Italian onion stew ahead?
Yes. The flavor holds up well when made a day ahead, and the stew may taste more blended after chilling. Refrigerate it within 2 hours, keep it covered, and reheat the amount you need to 165°F (74°C). Add a little broth or water if it has thickened in the refrigerator.

Can I use dried beans instead of canned?
Yes, provided the dried beans are fully cooked before they go into the stew. Prepare about 1 cup (200 g) dried cannellini beans according to their package directions; the cooked yield is usually enough to replace two 15-ounce cans. Add the cooked beans at the same point as the canned ones. Do not add uncooked dried beans directly to this recipe, because the stew’s short simmer is not enough to cook them.

How can I make the stew less sweet?
Use yellow or white onions rather than a large proportion of red onions, and finish with the full 2 teaspoons of red wine vinegar. Taste before adding more: a small additional splash can balance sweetness, but too much will make the broth taste sour. A little extra black pepper can also make the finish feel more savory.

What can I use instead of cannellini beans?
Great Northern beans, navy beans, or butter beans all work. Great Northern and navy beans are close in size and flavor; butter beans are larger and softer, so stir them in gently to avoid breaking them up. Chickpeas are another option, though they have a firmer texture and a more pronounced nutty flavor.

Is Italian onion stew a soup or a stew?
It sits between the two. The onions and beans make it substantial, while the broth keeps it spoonable. Use less broth or mash some beans for a thicker stew; add extra broth if you want a lighter, more soup-like bowl.
