Why it works: Green beans and tomato match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 113 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
The recipe
8 servingsIngredients
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Heat the olive oil in a large heavy pot over medium heat.
Add the chopped onions and minced garlic and cook, stirring often, for about 8 minutes until the onions are soft and translucent.
Add the rinsed, trimmed green beans, diced tomatoes, sugar and salt, and stir to combine.
Reduce the heat to low, cover the pot, and simmer for about 40 minutes, stirring every 10 minutes.
If the pot looks dry before the beans are tender, add a splash of water and keep simmering.
Uncover and cook for another 5 to 10 minutes until the beans are very tender and the sauce has thickened.
Taste and adjust the salt, then serve warm or at room temperature.
