Seafood is a quiet hero of the low deuterium kitchen. Prawns are a clean, sugar-free protein, and once you cook them in a low-deuterium fat like grass-fed butter, with nothing but garlic, lemon and herbs for company, you have a dish that is naturally aligned with a low deuterium diet from the first bite. Best of all, it is almost impossible to make it complicated.

Why This Is a Low Deuterium Recipe
This dish is naturally low in deuterium, so the choices are about keeping it that way.
| Standard choice | Low deuterium choice | Why |
|---|---|---|
| Breaded or battered prawns | Plain prawns | Skips the flour and starch of a coating |
| Seed or vegetable oil | Grass-fed butter or ghee | A low-deuterium fat that makes the garlic butter sing |
| Sweet chilli or sugary sauce | Lemon, garlic and herbs | All the flavour with none of the added sugar |
Ingredients
- 500g (1 lb) raw prawns, peeled and deveined
- 3 tbsp grass-fed butter or ghee
- 4 cloves garlic, minced
- Juice of ½ lemon, plus wedges to serve
- 2 tbsp chopped fresh parsley
- Pinch of chilli flakes (optional)
- Sea salt and black pepper, to taste
Instructions
- Dry the prawns. Pat the prawns very dry with paper towel and season with salt and pepper. Dry prawns sear rather than steam.
- Melt the butter. Warm a large skillet over medium-high heat and melt 2 tbsp of the butter until foaming.
- Cook the prawns. Add the prawns in a single layer and cook for 1 to 2 minutes on each side, until they turn pink and curl into a loose C shape. Do not overcook.
- Add garlic and finish. Lower the heat, add the remaining butter and the garlic, and cook for 30 seconds until fragrant. Stir in the lemon juice, parsley and chilli flakes and toss to coat.
- Serve. Serve straight away with the pan butter spooned over and lemon wedges alongside.
Why Seafood Suits a Low Deuterium Diet
Seafood earns its place for a simple reason: it is protein and fat with virtually no sugar or starch, which is exactly the profile a low deuterium diet favours. Prawns are lean and quick, while fattier seafood like salmon and sardines brings more of the naturally low-deuterium fat. Cooking them in grass-fed butter keeps the whole dish firmly in low-deuterium territory.
Serving Suggestions
These prawns are wonderfully versatile. Pile them over cauliflower rice or courgette noodles to catch the garlic butter, toss them through a green salad, or serve them as a light main with sauteed asparagus or spinach. They are also lovely cold the next day over leaves.
Storage and Meal Prep
Cooked prawns keep in an airtight container in the fridge for up to 2 days and are best eaten cold rather than reheated, since they toughen easily on a second cook. If you do reheat, do it very gently and briefly in the warm butter.
