Carrageenan Free Turmeric-Ginger Halibut with Eggplant & Zucchini Sheet-Pan Dinner
Sheet-pan dinners are already a weeknight hero, but this one earns extra points for being as vibrant as it is satisfying. Halibut fillets get rubbed down with a golden paste of turmeric, ginger, and cumin before roasting alongside eggplant, zucchini, cherry tomatoes, and sliced garlic — everything caramelizing together in one pan. A squeeze of fresh lemon juice and a scatter of parsley at the end brighten the whole thing up beautifully. For anyone navigating a carrageenan-free lifestyle, the challenge is often processed seafood products, sauces, and dairy-based marinades that sneak in thickeners and stabilizers. This recipe sidesteps all of that entirely — every ingredient is whole and unprocessed, from the fresh fish to the olive oil to the spices. The spice paste does double duty as both marinade and flavor builder, so there's no need for any packaged seasoning blends or store-bought sauces that might hide unwanted additives. It's clean, colorful, and genuinely delicious straight from the pan.
