Green beans are a reliable, low-oxalate vegetable that works as a side dish for virtually any meal. About 15 mg oxalate per half-cup — safely under the 25 mg threshold. They're available fresh, frozen, and canned (rinse canned to reduce sodium). Steam them, sauté with garlic and olive oil, or add to casseroles. The classic green bean casserole adds significant sodium from processed soup — the green beans themselves aren't the problem. For a kidney-stone-safe preparation: steam fresh or frozen green beans, toss with a little butter, and serve alongside chicken or fish.
