Alpha Gal Friendly 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 fillets all roasted 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 goes back into a hot oven. For anyone navigating alpha-gal syndrome, this recipe is a natural fit because it's built entirely around fish, plants, and olive oil — no mammalian meat, dairy, or hidden animal-derived additives anywhere in the ingredient list. That can be genuinely hard to find in a satisfying, protein-forward dinner, and this one delivers without any workarounds or substitutions. The trout comes out tender and fragrant, with the herby, nutty pesto forming a gorgeous crust as it roasts. A squeeze of fresh lemon at the table ties everything together and brightens the whole pan. It's the kind of recipe you'll want to keep in regular rotation.
