Dijon Salmon and Crispy Potatoes

A quick and easy way to prepare a fish dish the whole family will love!

We make Dijon Salmon and Crispy Potatoes at least once a fortnight at our place – the kids ask for it regularly! It’s easy – just 15 minutes of prep, then the oven does the rest of the work, cooking the fish and potatoes simultaneously. I love this recipe so much that I included it in my new cookbook Simple Dinners Every Day.

A marinade of garlic, dijon mustard and lemon is the perfect match for deliciously tender salmon.

The salmon is first marinated in a simple dijon mustard, garlic and lemon mixture, which is worth the extra step – it’s so delicious and restaurant-worthy, yet only takes a few minutes. However, sometimes, when things are crazy busy, I’ll just marinate the salmon in olive oil, salt and pepper and the flavour is still beautiful.

But the baby potatoes are the star of the show here. There’s no need to peel them, as it’s the skin that makes the potatoes extra crunchy. They are plonked in boiling water, before being slightly squashed on a baking tray using a spatula, then baked until golden brown and crispy. I love that there is no cutting, peeling or fussing involved. Super simple but SO delicious.

After being marinated in a garlicky mustard and lemon mixture, salmon is baked in the oven, along with smashed baby potatoes, then served with a creamy lemon dill sauce and a green salad.

I then love to make a delicious homemade creamy lemon dill sauce with honey, which you can either drizzle over the fish or serve on the side. Sometimes we make a tartare sauce instead, depending on our mood. This recipe makes a gorgeous weeknight dinner or a lazy weekend meal, and it’s also great for entertaining – it tastes “special”, but comes together with minimal effort.

If you have any salmon left over, we flake the salmon into a salad the next day for lunch. It can be eaten warm or cold – we love it with microwave wild rice and leaves or in a classic caesar. It’s equally delicious heaped onto a toasted bagel with cream cheese, red onion, capers and fresh dill. If you’re feeling fancy, you could make croquettes by combining the salmon with mashed potatoes, forming into patties and frying.

What sides can I serve with Dijon Salmon and Crispy Potatoes?

Although the salmon is served with crispy potatoes and a simple green leafy salad, steamed greens are also a good option. Try green beans, bok choy, broccoli or broccolini (tenderstem broccoli). A side of Freezer-friendly Garlic Bread would also be delicious.

Baby potatoes are boiled, then squashed and baked in the oven until deliciously crispy. The crunchy texture of the potatoes is a great combo with the tender, juicy salmon.

Can I use another type of fish?

Yes, you can substitute the salmon with barramundi or snapper fillets (or any other firm, white fish fillets), adjusting the cooking time accordingly. Barramundi fillets are slightly thicker than salmon and may require an extra 2–3 minutes. Aim for 16–18 minutes. Snapper fillets are slightly thinner and will cook a little faster. Reduce the cooking time to 12–14 minutes.

Only 15 minutes of prep, then let the oven do the rest of the work to create this delicious family-friendly Dijon Salmon with Crispy Potatoes recipe, which is served with a creamy lemon dill sauce and a green salad.
Prep 15 minutes
Cook 1 hour 5 minutes
Total 1 hour 20 minutes
Servings: 4

Ingredients

POTATOES
  • 700 g ( lb) baby potatoes, washed – no need to peel (see note 1)
  • 2 tbsp sea salt flakes
  • Olive oil spray
SALMON
  • 2 tbsp finely chopped fresh flat-leaf parsley
  • 1 lemon, juiced
  • 1 tsp freshly minced garlic
  • 1 tsp dijon mustard
  • ½ tsp sea salt flakes
  • ¼ tsp freshly cracked black pepper
  • 3 tbsp olive oil
  • 4 salmon fillets, skin on (the skin helps to keep the salmon’s shape when serving, but skin-off fillets can also be used)
CREAMY LEMON DILL SAUCE
  • 125 g (½ cup) whole-egg mayonnaise
  • 125 g (½ cup) Greek yoghurt (can be substituted with extra mayonnaise or sour cream)
  • 1 tsp dijon mustard
  • 3 tbsp finely chopped fresh dill
  • ½ lemon, juiced and zested
  • 1 tsp finely chopped capers
  • 1 tsp sea salt flakes
  • ½ tsp honey (optional)
  • 1 tbsp water (optional), see recipe
TO SERVE

Instructions

  • Make the crispy potatoes – Place the potatoes in a large pot and add enough water so they are covered by at least 2 cm (¾ inch). Add 1 tablespoon of the salt. Bring to the boil, then simmer over medium heat for 20–25 minutes or until the potatoes are tender enough to pierce with a fork. Use a colander to drain the potatoes, then allow them to steam in the colander for 5 minutes. Less moisture = crispier potatoes. It’s okay if the skins have split (extra crispiness!).
  • Preheat the oven to 220°C (425°F) (200°C/400°F fan-forced). (See note 2 for stovetop method.)
  • Drain the potatoes, then arrange them on a baking tray (lined with baking/parchment paper for easier cleanup). Use a spatula or the bottom of a glass to squash the potatoes so they are slightly flattened.
  • Sprinkle each potato with the remaining 1 tablespoon of salt and spray generously with olive oil.
  • Cook for 45 minutes or until crispy and golden on the bottom rack of the oven, leaving the top rack of the oven empty for the salmon, which will be added later.
  • To cook the potatoes in an air fryer – If making the potatoes in an air fryer, place the potatoes in a pot and cover them with water. Add 1 tablespoon of salt. Bring to the boil, then simmer for 15–20 minutes or until fork-tender. Drain.
  • Lightly flatten the potatoes with a spatula or the bottom of a glass. Arrange them in a single layer in the air fryer basket or tray, ensuring they don’t overlap to ensure even crisping.
  • Spray the potatoes generously with olive oil and sprinkle with the remaining 1 tablespoon of salt. Air fry at 200°C (400°F) for 15–20 minutes, shaking the basket halfway through, until golden and crispy.
  • Cook the salmon – In a small bowl, add the marinade ingredients: parsley, lemon juice, garlic, mustard, salt, pepper and olive oil. Use a whisk to combine well.
  • Place the salmon skin-side down on a baking tray lined with baking paper. Spoon the marinade over the salmon, then use the spoon or a brush to coat the salmon well.
  • Bake in the oven to cook for 15 minutes. The salmon needs to be added into the oven 30 minutes into the potato cooking time.
  • To cook the salmon in an air fryer – In a small bowl, whisk together the parsley, lemon juice, garlic, mustard, salt, pepper and olive oil. Brush the marinade generously over the salmon fillets.
  • Place the salmon fillets skin-side down in the air fryer basket (see note 3). Air fry at 180°C (350°F) for 8–10 minutes, or until the salmon is cooked to your preference.
  • Make the creamy lemon dill sauce – Combine the sauce ingredients in a small bowl and set aside.
  • Serve – Divide the potatoes among four plates, then top with the salmon. Serve with a side of mixed leaf salad, creamy lemon dill sauce and lemon slices. Alternatively, serve on a large serving platter for everyone to help themselves!

Recipe notes

Note 1 – The potato skin helps the potato stay intact and get extra crispy.
Note 2 – If you’d like to cook the fish on the stovetop instead, cook the salmon skin-side down in a hot pan for 3–4 minutes, then flip and cook for another 3 minutes or until done.
Note 3 – Add the salmon to the air fryer during the last 10 minutes of the potatoes cooking time so both finish together.

Make Ahead

Potatoes – The potatoes can be boiled and squashed ahead of time. Store them, covered, in the fridge for up to 3 days and roast when needed.
Sauce – The sauce can be prepared a day in advance (for best results) and kept in an airtight container in the fridge.
Salmon – Don’t marinate the salmon ahead of time. It is best marinated just before cooking (within 20 minutes) to stop the lemon curing the salmon and making it tough.

Leftovers

Store leftover salmon and potatoes in separate containers in the fridge for up to 2 days. Reheat the potatoes in the oven for crispiness and the salmon in a pan to keep it moist.
The sauce can be kept in the fridge for up to 3 days.

    This dinner was amazing!! It was simple to make, tasted incredible and the whole family loved it. I loved that most of the work was done by the oven and it was a perfect weeknight dinner. The lemon caper sauce was divine and even my 3 year old asked for seconds. It has definitely become a family favourite.

    Love love love it !!!! Thanks so much. Can I freeze the sauce by any chance ?

    • So glad you love this, Yulia. I haven’t tried freezing this and I don’t think I’d risk it as the texture would change too much. Thanks for the rating. Nic x

  11. Delicious. Prepped sauce and marinade ahead, so very quick to do. Husband not fond of salmon but wolfed this down and wanted seconds. Ideas for left over salmon and sauce the next day? (Potatoes all went in a flash!)

    • Hi Sara, I am so glad to hear you and hubby loved the recipe! Thank you so much for taking the time to comment. We love keeping it simple and flaking up the salmon in a salad the next day for lunch. It can be eaten warm or cold – we love it with microwave wild rice and salad leaves or in a classic caesar. It’s equally delicious heaped onto a toasted bagel with cream cheese, red onion, capers and fresh dill. If you’re feeling fancy, you could make croquettes by combining the salmon with mashed potatoes, forming them into patties and frying. Let me know if you end up trying any of these! Nic x
