Sesame Free Sheet Pan Tuna Steaks with Tomatoes & Green Beans
Sheet pan dinners don't get much more vibrant than this — seared tuna steaks nestled into blistered cherry tomatoes and charred green beans, all finished with a bright cilantro-lime dressing. The spice rub of cumin, smoked paprika, and turmeric gives the fish a warm, deeply savory crust that plays beautifully against the fresh acidity of the lime juice and garlic dressing. Every single ingredient here is naturally free of sesame in any form — no tahini, no sesame oil, no hidden seeds — so you can cook with total confidence. For anyone who has to scrutinize spice blends and sauces for hidden sesame, building your own rub from scratch like this is the cleanest possible approach. The vegetables roast first to get a head start, so by the time the tuna goes in, everything finishes together at exactly the right moment. It's a genuinely elegant weeknight meal that comes together on a single pan with minimal cleanup, and the drizzle of that herby dressing at the end ties the whole thing together in the best way.
