Sheet-Pan Old Bay Trout and Succotash

This vibrant sheet-pan trout and succotash is a fantastic way to enjoy fresh, high-protein seafood with minimal effort. By roasting everything on a single tray, the delicate flavour of the trout is perfectly complemented by the sweetness of the corn and the snap of the green beans. The Old Bay seasoning adds a classic touch of heat and spice, while the lemon-pepper mayonnaise provides a creamy, zesty finish that ties the whole dish together.

Ideal for a quick weeknight dinner or a healthy weekend lunch, this recipe uses a clever foil-parcel technique to steam the vegetables alongside the fish. This method ensures the succotash remains juicy and colourful while the trout stays moist and tender. It is a wholesome, balanced meal that delivers impressive results without the need for multiple pots and pans.

Ingredients for Sheet-Pan Old Bay Trout and Succotash

  • 2 whole butterflied trout (about 350g each), heads removed

  • 2 teaspoons Old Bay seasoning

  • 3 tablespoons unsalted butter, cut into small pieces, divided

  • 1 lemon, thinly sliced

  • 3 medium ears of corn, kernels cut from cobs (about 725ml )

  • 170g green beans, cut into 1" pieces

  • 1 large tomato, cut into 1" pieces

  • 1 teaspoon kosher salt

  • 180ml mayonnaise

  • 60ml fresh lemon juice

  • 1/2 teaspoons freshly ground black pepper

Arrange a rack in top third of oven; preheat to 232°C. Line an 18x13" rimmed baking sheet with foil. Lay trout open like a book, skin side down and alternating head-to-tail next to each other on one half of pan. Sprinkle flesh with Old Bay, then dot with half of butter. Arrange lemon slices over.

Drape a long (about 30") piece of foil crosswise over other half of pan. Toss together corn, green beans, tomato, salt, and remaining butter on foil. Fold edges up and over to create packet; pinch edges closed.

Roast until trout is opaque and cooked through, about 10 minutes. You want to check the thickest part of the flesh—if you need to lift a lemon to look at it, do so, and continue roasting until it’s totally opaque.

While fish is cooking, whisk mayonnaise, lemon juice, and pepper in a small bowl until smooth.

Divide trout and succotash among plates. Serve with mayonnaise sauce alongside.
