Low FODMAP Salmon Cakes

Crisp on the outside with a soft centre, Low FODMAP Salmon Cakes combine flaked salmon, mashed potato, and dill into an easy baked dish.

I must admit I’m not a huge seafood lover. However, I eat fish at least twice a week, so I’m always looking for different ways to serve it to the family and keep things interesting.

These Low FODMAP Salmon Cakes are one of those recipes I come back to often. They’re simple to prepare, easy to shape, and bake into soft, tender patties with a light golden crust.

This version keeps things light and low FODMAP, without losing flavour or texture. The mashed potato keeps the inside moist, while the outside holds together well.

What makes these patties stand out for me is the flavour combination. Dill and salmon have always worked well together in my kitchen.

It’s a pairing I first noticed during a trip to Norway as a teenager, where a simple plate of steamed salmon and potatoes tasted completely different with the addition of dill. Capers add a light, briny note that works well with the salmon.

These salmon cakes are very versatile. You can serve them as an appetiser, as a main with a side, or even inside a burger.

The aioli comes together quickly and stays Low FODMAP when made with suitable mayonnaise and garlic-infused olive oil. It adds a smooth, creamy finish alongside the salmon.

Reasons to Make Homemade Salmon Cakes

• Flexible enough to turn into a salmon burger, appetiser, or plated meal depending on what you need.
• Pairs easily with salads, rice, or vegetables and doesn’t need complicated sides.
• Makes a lighter alternative to meat-based patties without feeling like a compromise.

Key Ingredients for Low FODMAP Salmon Cakes

Salmon

Salmon gives the cakes their soft, flaky texture and rich flavour once baked. Fresh salmon fillets work best, especially skinless pieces, as they cook evenly and break apart easily.

Potato

Potato keeps the mixture soft and light, helping the cakes stay tender inside. Floury types like Russet or Yukon Gold mash smoothly and blend well with the salmon.

Dill

Dill adds a fresh, slightly grassy flavour that pairs naturally with fish. Fresh dill has a more delicate taste, though dried can be used in smaller amounts.

Capers

Bring a salty, briny note that contrasts with the salmon. They add small pockets of flavour throughout each bite.

Homemade Low FODMAP Aioli

The aioli is made with low FODMAP mayonnaise, I use Hellmann’s, combined with garlic-infused olive oil and lemon juice. It’s smooth and creamy with a light garlic note and adds richness while keeping the flavour well balanced.

Frequently Asked Questions

Extra Help from the Kitchen

Dry the Salmon Before Cooking – Pat the salmon dry with a paper towel before seasoning. Too much surface moisture can make the mixture softer than expected.

Let the Mixture Firm Slightly Before Shaping – If the mixture feels too soft, place it in the fridge for 10–15 minutes. It becomes easier to handle and holds its shape better when formed.

Use Damp Hands for Shaping – Lightly damp hands make shaping quicker and less messy. The mixture won’t cling, and the patties come out smoother.

Flatten Evenly for Consistent Cooking – Keep the patties the same thickness. Uneven shaping can lead to dry edges while the centre finishes cooking.

Let Them Rest Briefly After Baking – Leave the patties on the tray for a few minutes once out of the oven. They settle slightly and are easier to move without breaking.

Variations and Twists

Stir In Dijon Mustard – Mix in up to 1 tbsp Dijon mustard for a sharper savoury note that pairs well with dill and lemon. Check the label to avoid garlic or onion powders.

Fold in Lemon Zest – Add 1–2 tsp finely grated lemon zest for a more fragrant citrus note without adding extra moisture. It keeps the patties firm.

Swap Dill for Chives and Parsley – Replace dill with 1–2 tbsp chopped chives and parsley for a softer herbal finish.

Mix Through Low FODMAP Breadcrumbs – Add 2–3 tbsp low FODMAP breadcrumbs if the mixture feels too soft. Choose gluten-free options without ingredients like honey or inulin.

Finish With a Dill Sauce Instead of Aioli – Combine 2–3 tbsp low FODMAP mayonnaise, such as Hellmann’s, or lactose-free yogurt with fresh dill for a lighter, tangier sauce.

Storage and Shelf Life

Store the salmon cakes in an airtight container in the fridge for up to 3 days. They shouldn’t be left at room temperature for extended periods.

For freezing, place the cooked and cooled patties in a single layer before transferring them to a sealed container. They will keep well for up to 2 months while maintaining good texture.

Thaw overnight in the fridge before reheating. Reheat in the oven at 180°C – 355°F until warmed through to help keep their texture.
