This Baked Fish in Foil with Potatoes is an easy and gluten-free fish dinner that’s packed with flavor, nutrients, and zero fuss. Perfect for weeknights or casual entertaining, this foil-packet recipe features flaky cod, tender potatoes, and fresh thyme, all wrapped in buttery lemon goodness for a satisfying, no-mess meal.

Baking fish in foil is a fun way to cook fish and veggies together, in a way that yields the most delicious steamed-like fish and serving up individual portioned packets, without a big fishy mess!

I fell in love with this method of cooking fish back when I made this Baked Fish-in-Foil with Vegetables recipe and later on this Grilled Salmon in Foil with Vegetables.

Today I am giving the classic ‘fish and chips’ a fun twist by baking the fish fillets over a bed of buttery potato slices, seasoned with flaky sea salt, fresh thyme and a generous squeeze of fresh lemon juice. The foil packets go on a baking sheet and into the oven, until the fish is flaky and cooked to perfection.

Ingredients for oven baked fish and potatoes

• Fresh cod fillet – you can substitute for another fish that has similar texture and cook at about the same time. Such as halibut, bass and tilapia. Not recommended is swordfish, as it is a meaty fish and takes longer to cook.
• Yellow potatoes, thinly sliced – Substitute for pre-sliced, seasoned, frozen potato wedge.
• Butter – any type of butter will work. for dairy-free or vegan, use vegan butter
• Lemon – sliced plus freshly squeezed lemon juice when serving
• Sea salt and black pepper – to taste. You can use bay seasoning for more flavor
• Fresh thyme – during the summer months opt for seasonal herbs such as parsley, cilantro and dill. Note these fresh herbs are best used in garnishing.

👉🏻 This foil packet cod with lemon and butter is very simple to make and it only requires few ingredients, as you can see. We first bake the buttery potatoes alone to assure perfectly baked potatoes with crispy edge. Then we add the fish and bake until flaky.

Make ahead and storage

You can assemble the foil packets up to 1 day ahead and keep them in the fridge until ready to bake. Store leftovers in an airtight container for up to 2 days and reheat gently in the oven or air fryer.

This gluten-free fish dinner is great for a year round dinner idea and it’s a great source or clean protein. You can cook the fish packets on the grill during the summer months, and it is perfectly paired with a side green salad.

Ingredients 

1x2x3x

• ▢ 1 1/2 – 2 lb fresh cod
• ▢ 3 medium yellow potatoes, sliced
• ▢ 5 tbsp unsalted butter* (for DF/Vegan sub for vegan butter)
• ▢ 1 lemon, sliced
• ▢ 1 pinch sea salt and pepper, to taste
• ▢ fresh thyme

Instructions 

• Pre-heat oven to 425F degrees. Line a large sheet pan with four good-sized pieces of aluminum foil. Set aside
• Slice the potatoes to about 1/4 inch thick. Dip the potato slices into a bowl with melted butter, then arrange the potato slices on the foil overlapping each other, forming a bed of potatoes. Season the potato slices with sea salt and top with fresh thyme. Repeat until all four pieces of foil have a layer of potatoes. Bake for 20-25 minutes.
  
• Meanwhile prepare the cod by cutting it into four equal size pieces. Brush with remaining butter and season with sea salt, freshly ground pepper and fresh tyme. Top with lemon slices.
• Place a piece of cod on top of each potato bed. Gently fold the sides of the foil up, not completely wrapping the fish but rather forming a pocket. Bake for 18-20 minutes or until fish is flaky.
• Serve each fish packet with fresh lemon slices, fresh herbs and a side of green salad

Notes

Note: if the fish has a thin end, fold it under to maintain the same size and thickness for even cooking
