This recipe for slow-cooked green beans transforms a simple vegetable side into a rich, savoury dish packed with Mediterranean flavour. Unlike traditional quick-blanched vegetables, these beans are gently simmered in a generous amount of extra-virgin olive oil, balsamic vinegar and chicken stock. The long cooking process allows the beans to absorb the aromatic notes of garlic, bay and a hint of chilli, resulting in a silky texture and a deep, complex finish.
As a naturally dairy-free dish, these beans are an excellent accompaniment to a Sunday roast or grilled meats. The acidity of the aged balsamic vinegar perfectly balances the richness of the olive oil, making this a sophisticated addition to your dinner repertoire. For a vegetarian alternative, simply swap the chicken stock for a high-quality vegetable bouillon to maintain that essential depth of flavour.

1.8kg green beans (preferably Blue Lake variety), trimmed
240ml extra-virgin olive oil
1 medium Spanish onion, thinly sliced
4 garlic cloves, smashed and peeled
1 bay leaf

How to make Long-Cooked Green Beans
Bring large pot salted water to boil. Add green beans and boil, uncovered, until slightly tender but still crisp, about 3 to 4 minutes. Drain and set aside.
In large saucepan over moderately high heat, heat 120ml olive oil until hot but not smoking. Add onions, garlic, bay leaf, and chilli pepper. Sauté, stirring occasionally, just until soft, about 4 to 5 minutes. Add green beans, chicken stock, vinegar, salt, pepper, and remaining 120ml olive oil. Bring to simmer, then reduce heat to low and simmer, covered, 30 minutes. Strain, remove chilli and bay leaf, and serve immediately.
