Baked Haddock

A clean, simple dinner of flaky baked haddock with green beans and new potatoes. High in protein, light, and gentle on the stomach.

Why this works on GLP-1

Haddock is a lean white fish that delivers a lot of protein for very few calories, making it an ideal choice on GLP-1 medication where appetite is lower and protein helps protect lean muscle during weight loss. Baking rather than frying keeps it light and needs almost no added fat.

Green beans add fibre and volume for very little, and a modest portion of new potatoes gives gentle, satisfying carbohydrate without overloading the plate. It is an easy, no-fuss dinner that feels clean and restorative.

Ingredients · makes 1 serving

Haddock filletFresh or defrosted 170 g
Baby potatoesHalved 150 g
Green beansTrimmed 100 g
LemonHalf, sliced or juiced 1/2
Avocado oilA little, for the fish and potatoes 1 tsp
Herbs and seasoningParsley or dill, garlic, salt and pepper to taste
To finish, optionalA drizzle of walnut oil, capers, or a little more lemon to taste

Method

Start the potatoes. Heat the oven to 200°C (400°F). Toss the halved baby potatoes with a little avocado oil and seasoning, spread on a tray, and roast for 20 minutes to give them a head start.
Add the haddock. Place the haddock fillet on the tray, brush with a little avocado oil, season, and top with lemon slices and herbs. Bake for 12 to 15 minutes, until the fish is opaque and flakes easily with a fork.
Cook the green beans. While the fish bakes, steam or boil the green beans for 3 to 4 minutes, until just tender and still bright.
Serve. Plate the haddock with the potatoes and beans, and finish with a squeeze of lemon, capers, or a drizzle of walnut oil. Eat slowly to gauge fullness on a reduced appetite.
