Pisto is Spain's answer to Provence's ratatouille, and the two dishes are related through Moorish agricultural traditions that spread eggplant, peppers, and zucchini across the Mediterranean. The Manchegan version (pisto manchego) is the most famous: the vegetables are sweated separately in olive oil before combining, the tomato is added last and cooks down until it's concentrated, and the result is a thick, jammy stew rather than a soup. In La Mancha, it is often served with a fried egg — the yolk breaking into the red-orange stew — or alongside slices of cured meat and bread. Pisto improves considerably over 24 hours in the fridge, making it an excellent thing to cook in quantity and eat across several days.
Heat the olive oil in a large skillet or saucepan over medium heat.
Add the chopped onion and garlic and sauté until softened and translucent, about 5 minutes.
Add the diced red and green bell peppers to the skillet and cook for another 5-7 minutes until they begin to soften.
Stir in the diced zucchini and eggplant, cooking for an additional 5 minutes until the vegetables start to soften.
Add the diced tomatoes (or canned tomatoes) to the skillet, along with the sugar. Mix well and bring to a simmer.
Reduce the heat to low and let the mixture simmer for about 20-30 minutes, stirring occasionally, until all the vegetables are tender and the flavors are well combined.
Season with salt and pepper to taste.
If the mixture is too thick, you can add a little water to reach the desired consistency.
Garnish with freshly chopped parsley before serving.
Pisto can be served hot or at room temperature, often accompanied by crusty bread or as a side dish to meat or fish.
Spanish vegetable stew: zucchini, eggplant, pepper, and tomato in olive oil; similar to French ratatouille.
Castilla-La Mancha; Moorish agricultural influence; pisto manchego is the definitive version.
Zucchini, eggplant, red pepper, onion, ripe tomatoes, olive oil, and garlic.
Cook each vegetable separately before combining — this prevents watery texture and allows each one to concentrate its flavor.
Fried egg on top, crusty bread, sliced jamón or chorizo; also excellent as a base sauce for grilled fish.
