Oats 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 silky trout fillets all coming 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 a hot oven. Everything is naturally free of oats and oat-derived ingredients, so there's no need to scrutinize labels or worry about hidden grains sneaking into your dinner. The walnut pesto does double duty here — it keeps the fish moist as it roasts while layering in a rich, herby depth that store-bought sauces rarely match. Fingerling potatoes roast cut-side down first so they develop that irresistible golden crust before the rest of the ingredients even hit the pan, which is a small step that makes a big difference. A squeeze of lemon at the table ties everything together and makes the whole dish taste even brighter. It's a complete, satisfying meal with almost no cleanup — exactly what a sheet pan dinner should be.
