Almond 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 roasting together on one pan. The real star is the homemade walnut pesto, blitzed together in a food processor with fresh basil, garlic, and a bright hit of lemon juice, then spooned generously over each fillet before it goes back into the oven. Walnuts bring that rich, buttery depth you want in a pesto without leaning on almonds or pine nuts, making this a genuinely satisfying option for anyone navigating tree nut restrictions around almonds specifically. The pesto clings to the fish as it roasts, forming a fragrant, herb-packed crust that keeps the trout incredibly moist. Everything comes together in a single pan with a straightforward staggered roasting method, so cleanup is minimal and timing is forgiving. A squeeze of lemon over the whole thing at the table pulls every component into focus. It's the kind of recipe you'll find yourself coming back to on rotation.
