Pescatarian Sheet Pan Tuna Steaks with Tomatoes & Green Beans
This sheet pan dinner is the kind of weeknight meal that looks like you tried way harder than you actually did. Tuna steaks get rubbed with a warm spice blend of cumin, smoked paprika, and turmeric before roasting alongside blistered cherry tomatoes and charred green beans — all on a single pan, all at the same time. The real finishing touch is a bright cilantro-lime dressing whisked together while everything roasts, which pulls the whole dish together with a hit of citrus and fresh herb flavor. Because tuna is the star protein here, there's no need to worry about swapping anything out or navigating complicated substitutions — it fits naturally into a seafood-forward way of eating without any compromise on satisfaction. The high oven heat does the heavy lifting, coaxing the vegetables into something tender and jammy while keeping the tuna juicy and full of flavor. Cleanup is minimal, the flavors are anything but, and a few lime wedges on the side make it feel genuinely restaurant-worthy.
