Carrageenan Free Pesto-Walnut Trout with Green Beans & Fingerling Potatoes Sheet Pan Dinner

This sheet pan dinner is the kind of weeknight meal that looks like you spent way more effort than you actually did — golden fingerling potatoes, crisp-tender green beans, and flaky trout all coming together on a single pan. The real star is the homemade walnut pesto, blitzed together from fresh basil, raw walnuts, garlic, and lemon juice, then spooned generously over each fillet before it hits the oven. Because everything here is built from whole, recognizable ingredients, you sidestep the processed sauces and store-bought condiments that so often sneak in additives like carrageenan without any obvious warning on the label. The pesto clings to the fish as it roasts, creating a herby, nutty crust that keeps the trout incredibly moist at the center. Roasting everything at 425°F means the potatoes get properly caramelized on their cut sides while the green beans pick up just a little color at the tips — no soggy vegetables here. A squeeze of lemon at the table brightens the whole plate and ties the flavors together beautifully. It's a genuinely satisfying dinner that proves clean, additive-free cooking doesn't have to mean boring.
