This single serving ratatouille is a classic French vegetable stew made with zucchini, tomatoes, bell peppers, onion, and garlic, cooked in olive oil until tender and flavorful.
Heat the olive oil in a 10-inch skillet over medium heat. Add the onion, zucchini, red bell pepper, and ⅛ teaspoon of salt. Cook, stirring occasionally, for about 8 minutes until the vegetables soften.
Stir in the tomato, garlic, Italian seasoning, ⅛ teaspoon of salt, and black pepper. Cook for 3 minutes, until the tomatoes release their juices and everything is tender.
Transfer to a bowl and sprinkle with Parmesan cheese, if using.
Notes
Cut Vegetables Evenly: Chop the vegetables into similar-sized pieces so they cook at the same rate.
Do Not Overcrowd the Pan: Cook in a single layer so the vegetables sauté instead of steam.
Cook Until Tender, Not Mushy: The vegetables should be soft and fully cooked but still hold their shape.
Season at the End: Taste before serving and adjust the salt and herbs once the vegetables have softened and concentrated in flavor.
If doubling this recipe, use a larger skillet or cook in batches so the vegetables sauté evenly.
