Pan-Fried Salmon with Sweet Potato Mash and Sautéed Spinach
A gut-friendly trio rich in omega-3s, prebiotic fibre and magnesium to nurture your microbiome and support healthy digestion.
Ingredients
- 2 fresh salmon fillets (approx. 150g each, skin on)
- 300g sweet potato (approx. 1 large sweet potato, peeled and cut into chunks)
- 150g fresh spinach (baby spinach preferred)
- 2 tablespoons extra-virgin olive oil (divided between preparations)
- 1 tablespoon coconut oil (for the spinach)
- 60ml coconut milk (for the mash)
- 1 teaspoon freshly grated ginger
- Juice of half a lemon
- Unrefined sea salt and freshly ground black pepper
- A few fresh coriander leaves (optional, to garnish)
Instructions
Preparation Steps
-
Prepare the salmon marinade. In a small bowl, combine the lemon juice, grated ginger, and a pinch of salt and pepper. Place the salmon fillets in a dish and spoon the marinade over them. Leave to rest for 5–10 minutes at room temperature. This brief step boosts the dish's antioxidant content without compromising the prebiotic properties of the vegetables.
-
Steam the sweet potato. Place the sweet potato chunks in a steamer basket set over a pan of gently simmering water. Cover and cook for 15–20 minutes, until a knife slides through easily. Steaming preserves more resistant fibre and vitamins than boiling directly in water.
-
Make the sweet potato mash. Transfer the cooked chunks to a large bowl. Add the coconut milk and a pinch of salt, then mash with a fork or a potato masher — avoid using an electric blender, as this helps preserve retrograded resistant starch, which feeds your beneficial gut bacteria. Adjust the texture to your liking and keep warm.
-
Pan-fry the salmon. Heat one tablespoon of olive oil in a non-stick or stainless steel frying pan over a medium heat (approx. 160–180°C). Place the fillets skin-side down. Cook without moving them for 3 minutes, until the skin is golden and crisp. Carefully turn the fillets and cook for a further 2 minutes on the flesh side. The centre should remain slightly pink (around 55°C at the core) to preserve as many omega-3s as possible and limit the formation of pro-inflammatory compounds. Set aside somewhere warm.
-
Sauté the spinach. Wipe the pan clean and return it to a high heat with the coconut oil. Add all the spinach at once and sauté, stirring constantly, for 1–2 minutes until just wilted. This quick cooking method reduces oxalate content by around 50%, releases bioavailable lutein, and preserves the fibre and prebiotic polyphenols. Season with a pinch of salt.
-
Plate up. Spoon a generous quenelle or dome of sweet potato mash into the centre of each plate. Arrange the sautéed spinach alongside, then gently place the salmon fillet on top of or beside the mash. Drizzle a little raw olive oil over everything for a final anti-inflammatory touch. Scatter over a few fresh coriander leaves if you wish.
-
Serve immediately. This dish is best enjoyed hot, straight from the pan, to make the most of the salmon's texture and the creaminess of the mash. It will keep in the fridge for up to 24 hours in an airtight container.
💡 Gut-Friendly Tips
-
For sensitive individuals (IBS / low-FODMAP): limit sweet potato to 150g per portion to stay within the thresholds recommended by Monash University and avoid excess mannitol. If you are particularly sensitive to oxalates, opt for baby spinach or swap for sautéed courgette, which is equally gentle on the gut.
-
Histamine intolerance: always choose fresh salmon (not frozen for more than 24 hours) to limit histamine accumulation, whilst retaining all the valuable omega-3 fatty acids.
-
Microbiome tip: allowing the mash to cool slightly before reheating the following day further increases the proportion of retrograded resistant starch (RS3) — a prebiotic particularly appreciated by Bifidobacterium and Ruminococcus bromii.
-
Coconut milk-free option: replace the coconut milk with a drizzle of olive oil and a splash of the steaming water for an equally creamy mash that is naturally dairy-free and lower in saturated fat.
