French Bean Stew with White Beans and Herbs

French bean stew is a rustic, French-inspired pot of green beans, potatoes, tomatoes and white beans simmered in a fragrant vegetable broth. This version is hearty enough to serve as a main course, yet light and brothy rather than creamy. Green bean stews vary from household to household, so think of this as a flexible country-style recipe, not a single definitive regional formula.

Ingredients

Use fresh green beans for the best color and bite. Yukon Gold potatoes hold their shape during simmering, while canned cannellini beans make the stew filling without adding a separate soaking or cooking step. The herbs and tomato give the broth a savory, gently sweet character; lemon at the end keeps the flavors lively.

2 tablespoons olive oil (30 ml)
1 medium yellow onion, diced, about 1 cup (150 g)
2 medium carrots, diced, about 1 cup (160 g)
2 celery ribs, diced, about ¾ cup (80 g)
3 garlic cloves, finely chopped, about 1 tablespoon (9 g)
1 tablespoon tomato paste (16 g)
1 teaspoon dried thyme (1 g)
½ teaspoon dried rosemary, lightly crushed (0.5 g)
½ teaspoon fine salt (3 g), plus more to taste
¼ teaspoon freshly ground black pepper (0.5 g)
4 cups low-sodium vegetable broth (946 ml)
1 can diced tomatoes, 14.5 ounces (411 g), with their juices, about 1¾ cups
1 pound Yukon Gold potatoes, cut into ½-inch cubes, about 3 cups (450 g)
1 bay leaf
1 pound fresh green beans, trimmed and cut into 1½-inch lengths, about 4 cups (450 g)
1 can cannellini beans, 15 ounces (425 g), drained and rinsed; about 1½ cups (240 g) drained
1 tablespoon fresh lemon juice (15 ml)
2 tablespoons chopped fresh parsley (8 g)

If you cannot find cannellini beans, great Northern or navy beans are practical substitutes. They have a similar mild flavor, though navy beans tend to soften a little more. Fresh thyme can replace dried thyme: use 1 tablespoon (about 3 g) and remove the stems before serving. If you have only regular-sodium broth, start with less added salt and adjust after the stew has simmered.

Instructions

Prepare the vegetables. Dice the onion, carrots and celery; chop the garlic; cube the potatoes; and trim and cut the green beans. Drain and rinse the cannellini beans. This should take about 20 minutes if you work through the ingredients in that order. Keep the cut potatoes in a bowl while you prepare the other vegetables; there is no need to soak them.
Soften the aromatic vegetables. Set a large, heavy pot or Dutch oven over medium heat and add the olive oil. When it is warm, add the onion, carrots and celery. Cook for about 8 minutes, stirring every minute or two, until the onion is translucent and the carrots have started to soften. If the vegetables begin sticking before they soften, lower the heat rather than adding a lot of extra oil.
Build the base. Add the garlic, tomato paste, thyme, rosemary, salt and black pepper. Stir constantly for 1 minute, until the garlic smells fragrant and the tomato paste darkens slightly. Keep the garlic moving so it does not scorch, which can give the broth a bitter taste.
Add the broth and potatoes. Pour in the vegetable broth and diced tomatoes, scraping the bottom of the pot with a wooden spoon to release any browned bits. Add the potatoes and bay leaf. Raise the heat until the liquid reaches a gentle boil, which usually takes about 4 minutes, then reduce the heat to maintain a steady simmer.
Simmer until the potatoes are nearly tender. Cover the pot and simmer for 20 minutes. Check that the liquid is bubbling gently rather than boiling hard; vigorous boiling can break up the potatoes and make the broth cloudy. At the end of this stage, a knife should enter a potato cube with some resistance, because the green beans still need time to cook.
Cook the green beans, then add the white beans. Stir in the green beans and simmer uncovered for 8 minutes. Add the drained cannellini beans and continue simmering for 4 minutes, until the potatoes are tender and the green beans are cooked through but still hold their shape. Taste a bean before deciding whether it needs another minute or two; very thin beans cook faster than thick ones.
Finish and season. Remove and discard the bay leaf. Stir in the lemon juice and parsley, then taste the broth. Add more salt, pepper or lemon a little at a time. Let the stew stand off the heat for 2 minutes so the flavors settle, then ladle it into warm bowls. If it seems thicker than you like, stir in a splash of hot broth or water.

Tips

Cut vegetables to similar sizes. Aim for potato cubes close to ½ inch and green bean pieces around 1½ inches. Uniform pieces cook at roughly the same rate, so you are less likely to get mushy potato edges alongside hard centers. If some potatoes are noticeably larger, cut them down before they go into the pot.
Keep the simmer gentle. A hard boil can break up the potatoes and turn the beans soft before the broth has had time to develop flavor. Look for small, steady bubbles at the surface. If the pot is bubbling rapidly even at low heat, move it to a smaller burner or reduce the heat further.
Use frozen beans when needed. Frozen cut green beans work if fresh ones are unavailable. Add them straight from the freezer and begin checking for tenderness after about 6 minutes; they may need less time than fresh beans. The finished stew can be a little softer, but the flavor remains well balanced.
Adjust the broth at the end. Canned tomatoes, broth and beans differ in saltiness, so the measured salt is a starting point. Taste only after the stew has simmered and the lemon is added. If it tastes flat, try a small pinch of salt or another teaspoon of lemon before adding more herbs.

Serving Suggestions

Serve the stew hot in wide bowls, with crusty bread for dipping into the tomato and herb broth. A slice of toasted sourdough or a plain baguette works especially well because it adds texture without competing with the vegetables. For a more substantial meal, offer a green salad dressed with a sharp vinaigrette alongside it, or spoon the stew over a small portion of cooked rice, barley or farro.

At the table, set out extra chopped parsley, black pepper and lemon wedges so everyone can finish a bowl to taste. A little grated hard cheese is an optional savory topping, although the dish is already satisfying without it. If serving several people, keep the pot covered off the heat for only a short time; the beans will continue softening in the hot broth. Ladle promptly for the firmest vegetables.

Variations

Make it more Provençal in spirit. Stir in ½ cup (about 75 g) pitted, halved Niçoise or Kalamata olives during the last few minutes, and use a little extra parsley. Olives add a salty, briny note, so taste before adding more salt. This is a flavor variation rather than a claim that the stew follows one fixed regional recipe.

Add leafy greens. Stir in 2 packed cups (60 g) baby spinach during the final minute, or add 3 cups (about 90 g) chopped kale with the green beans and allow a few extra minutes for it to soften. Spinach wilts quickly and makes the broth greener; kale stays more substantial and may need 3 to 5 additional minutes.

Use another bean or make it spicier. Butter beans give the stew a creamy texture, while chickpeas make it firmer and more distinct in the bowl. For gentle heat, add ¼ teaspoon red pepper flakes with the garlic. You can also replace the dried rosemary with an equal amount of dried herbes de Provence, if available; blends vary, so check whether yours already contains salt.

Make the broth richer. Mash a few potato pieces and beans against the side of the pot, then stir them back in. This thickens the liquid without flour or cream. For a lighter, soupier bowl, add up to ½ cup (120 ml) extra broth at the end. Add liquid gradually so the tomato and herb flavors do not become diluted.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours of cooking, in a covered shallow container. The stew keeps for 3 to 4 days in the refrigerator. The potatoes and green beans will soften as they sit, so the texture on the second day is less firm, but the broth often tastes more blended. For longer storage, freeze portions in airtight freezer-safe containers for up to 2 to 3 months for best quality. Leave a little headspace for expansion and thaw overnight in the refrigerator.

Reheat a portion in a saucepan over medium-low heat, stirring occasionally, until it is steaming throughout and reaches 165°F (74°C). Check the center with a food thermometer, especially when reheating a large portion. In a microwave, cover loosely, heat in short intervals, and stir between intervals so the center warms evenly; confirm it reaches 165°F (74°C). Add a splash of water or broth if the stew has thickened. Avoid repeatedly cooling and reheating the whole pot; warm only what you plan to serve.

Frequently Asked Questions

Are French beans the same as green beans?
In many English-language recipes, French beans means green beans, often the slender type called haricots verts. The name can refer to different varieties or sizes depending on the market. This recipe works with ordinary fresh green beans; if you use very thin haricots verts, check them earlier because they can become tender faster.

Can I make this stew ahead?
Yes. You can prepare it a day ahead and refrigerate it once it has cooled enough to store safely, within 2 hours of cooking. The vegetables will soften somewhat overnight. For the freshest texture, cook the stew through the potato stage, cool and refrigerate it, then bring it back to a simmer and add the green beans and cannellini beans for their final 12 minutes before serving.

Can I use canned green beans?
You can, but they are already cooked and much softer than fresh beans. Drain them and stir them in with the cannellini beans during the final 4 minutes, just long enough to heat them through. Adding them at the beginning of the green-bean simmer is likely to make them break apart.

How can I make the stew thicker?
Mash some of the cooked potatoes and white beans into the broth, or simmer the finished stew uncovered for a few extra minutes. The first option thickens it without reducing the amount of liquid; the second concentrates the broth. Keep the heat gentle and stir occasionally so the potatoes do not catch on the bottom of the pot.

Is this stew vegan and gluten-free?
As written, it is vegan and gluten-free if the vegetable broth and canned ingredients are labeled accordingly. Check broth labels for ingredients that do not suit your needs, and serve it with bread or other sides that match your preferences. The optional cheese serving suggestion is not vegan, so leave it off or choose a suitable plant-based alternative.
