Pecan Free Pesto-Walnut Trout with Green Beans & Fingerling Potatoes Sheet Pan Dinner
Sheet pan dinners are a weeknight lifesaver, and this one delivers serious flavor without a lot of fuss — tender trout fillets blanketed in a bright, herby walnut pesto alongside golden fingerling potatoes and crisp-tender green beans. The homemade pesto comes together in a food processor in under a minute, using fresh basil, raw walnuts, garlic, and a squeeze of lemon juice for a sauce that's punchy and aromatic. Everything roasts together on a single pan at 425°F, so the potatoes get caramelized cut-sides, the green beans pick up a little color at the tips, and the fish stays moist and flaky under that gorgeous green crust. Because the pesto is made entirely from scratch with whole, straightforward ingredients, there's no guesswork about what's actually in it — walnuts are the nut of choice here, and nothing else sneaks in. A squeeze of fresh lemon over the top right before serving ties the whole dish together and makes the flavors pop. It's the kind of meal that looks impressive enough for company but is honestly easy enough to pull off on a Tuesday night.
