I’ll be honest, this started as a way to use up half a fillet of smoked haddock sitting in my fridge. It turned into the soup I make every time it’s cold out and I want something warm that still fits a low carb week.
Keto Smoked Haddock Chowder swaps the usual potatoes for chunks of cauliflower, so you get that same soft bite without the carbs. Cream cheese and heavy cream do the thickening work instead of flour.
The smoked haddock poaches right in the broth, so it picks up flavor from the leek and celery instead of the other way around. The skin comes off after cooking, once it’s warm and easy to peel.
One bowl is a full dinner. It’s smoky, creamy, and filling enough that you won’t miss the bread basket.
Why You’ll Love This Recipe
- Ready in about 40 minutes, one pot start to finish
- About 11g net carbs per bowl, so it fits a keto plan
- Cauliflower stands in for potato without losing the chowder feel
- Smoky, creamy, and filling enough to be dinner on its own
Ingredient Notes
- smoked haddock: Look for naturally smoked, undyed fillets if you can find them. Skin-on holds together better during poaching, and peels off easily once cooked.
- cauliflower: Cut florets small, about 2 cm, so they turn tender in the same 8 to 10 minutes the broth needs to simmer.
- cream cheese: Use a full-fat block, softened at room temperature, so it whisks into the broth without lumps.
- heavy cream: Full-fat cream keeps the chowder thick without flour. Half-and-half works but gives a thinner bowl.
- leek: Slice and rinse well between the layers, grit likes to hide in the white part.
- smoked paprika: Optional, but it deepens the smoky flavor if your haddock is on the milder side.
Creamy Keto Smoked Haddock Chowder with Cauliflower
Ingredients
Method
- Melt the butter in a 26 cm / 5-quart Dutch oven over medium heat.
- Add the leek and celery. Cook for 5 to 6 minutes, stirring often, until soft and starting to turn translucent.
- Add the garlic and cook for 30 seconds until fragrant.
- Stir in the cauliflower, stock, bay leaf, and smoked paprika. Bring to a simmer.
- Simmer uncovered for 8 to 10 minutes, until the cauliflower is fork-tender.
- Place the smoked haddock fillets into the broth, skin side down. Cover and poach for 6 to 8 minutes, until the fish flakes easily and reaches 145 F / 63 C in the thickest part.
- Lift the fish onto a plate. Once cool enough to handle, peel off and discard the skin, then break the fish into large flakes. Discard the bay leaf.
- Lower the heat so the broth is barely simmering. Whisk in the cream cheese a little at a time until smooth, then stir in the heavy cream.
- Simmer gently for 2 to 3 minutes, until lightly thickened. Do not let it boil hard or the cream can split.
- Return the flaked haddock to the pot and warm through for 1 to 2 minutes. Season with black pepper and salt to taste.
- Ladle into bowls, scatter with parsley, and serve with lemon wedges.
Notes
- Poach the haddock in the same broth so it never dries out.
- Peel the skin off once cooled, it slides right off warm cooked fish.
- Cut cauliflower to 2 cm pieces so it cooks in the same window as the broth.
- Taste before salting, smoked haddock and stock are already salty.
Tips for Success
- Poach the haddock gently, skin side down, so it flakes instead of turning tough.
- Soak smoked haddock in milk for 20 minutes first if you want to mellow the saltiness.
- Cut cauliflower into small 2 cm pieces so it cooks in the same window as the broth.
- Whisk cream cheese into warm, not boiling, broth to keep the chowder smooth instead of grainy.
- Taste before adding salt. Smoked haddock and stock both carry a lot of sodium already.
Variations
- Swap haddock for smoked cod or undyed smoked pollock for a milder, less salty chowder.
- Add 100g cooked bacon lardons with the leeks for a smokier, richer bowl.
- Stir in a handful of baby spinach at the end for color and extra greens without added carbs.
Storage and Reheating
Keto Smoked Haddock Chowder keeps in the fridge for 3 to 4 days in an airtight container.
Reheat gently on the stovetop over low heat, stirring often, for 5 to 7 minutes until steaming. Add a splash of stock or cream if it’s thickened up too much in the fridge.
Freezing isn’t a good idea here. The cream and cream cheese base tends to separate and turn grainy once thawed, so it’s best made fresh or kept refrigerated.
Serving Suggestions
Keto Smoked Haddock Chowder is a full dinner on its own, but a side salad with a sharp vinaigrette cuts through the richness.
Low carb crackers or a slice of almond flour bread are good for scooping up the broth. A soft-boiled egg on top, similar to a smoked mackerel egg bowl, adds extra protein if you want a heartier bowl.
Finish with a squeeze of lemon at the table. It wakes up the smoky flavor more than you’d expect.
FAQ
Why did my keto smoked haddock chowder turn grainy instead of smooth?
Grainy chowder usually means the cream cheese hit a hard boil or the pot got too hot too fast. Lower the heat before whisking in the cream cheese, add it in small pieces, and keep the broth at a bare simmer once the dairy goes in. A quick fix is whisking in an extra splash of warm cream off the heat.
Can I use smoked cod instead of smoked haddock in this chowder?
Yes, smoked cod works well and poaches the same way, 6 to 8 minutes until it flakes and hits 145 F / 63 C. It’s slightly milder than haddock, so you may want a touch more smoked paprika. Unsmoked cod also works if you can’t find smoked fish, though the chowder tastes less smoky.
Can I freeze keto smoked haddock chowder?
I don’t recommend freezing this chowder because the cream and cream cheese base tends to separate and turn grainy once thawed. It keeps well in the fridge for 3 to 4 days instead. If you want to plan ahead, chop the vegetables and portion the stock a day early, then poach the fish and add the dairy fresh.
What goes well with keto smoked haddock chowder?
A side salad with a sharp vinaigrette cuts through the richness, and low carb crackers or almond flour bread are good for scooping up the broth. A squeeze of lemon on top wakes up the smoky flavor. I also like a soft-boiled egg dropped on top for extra protein.
Is keto smoked haddock chowder gluten free?
Yes, this chowder is gluten free as written since it’s thickened with cream cheese and heavy cream instead of flour. Just check your stock’s label, since some brands add gluten as a thickener or flavor carrier. The rest of the ingredients, haddock, cauliflower, and leek, are naturally gluten free.
How is this different from a traditional New England haddock chowder?
Traditional New England chowder leans on potatoes and sometimes flour or crackers to thicken the broth, which adds carbs this version skips. Keto Smoked Haddock Chowder uses cauliflower and cream cheese instead, so the texture stays thick and creamy without the starch. The smoky haddock flavor stays the same either way.
