Citric Acid Free Turmeric-Ginger Tuna Steaks with Tomatoes & Green Beans Sheet-Pan Dinner
Sheet-pan dinners are weeknight gold, and this one delivers bold, warming flavors without relying on any acidic marinades or citrus-based sauces in the cooking process. The spice rub — built from turmeric, ginger, smoked paprika, and cumin — does all the heavy lifting, creating a deeply aromatic crust on the tuna that smells incredible the moment it hits the hot oven. Cherry tomatoes and green beans roast alongside the fish, picking up the garlic and olive oil as they blister and soften into something almost jammy. For anyone navigating a citric acid restriction, packaged spice blends and bottled sauces are often the sneaky culprits, but here every ingredient is straightforward and easy to verify. The lemon wedges served on the side let each person control exactly how much — or how little — they want, keeping the dish fully flexible at the table. Everything comes together on a single pan, which means less cleanup and more time actually enjoying a genuinely satisfying, protein-packed meal.
