Dairy-Free Fish Chowder for Acid Reflux: A Gentle Recipe

From Oliver’s kitchen notes

A chowder inspired by living with reflux

I’ve dealt with acid reflux for as long as I can remember. It was especially difficult for me during stressful periods in the UK, when the pressure of daily life seemed to make an already frustrating problem harder to manage. I still love food, and I did not want every comforting meal to feel like a choice between flavour and worry.

This fish chowder is one practical way to make the bowl creamy without using heavy cream. Potatoes bring body to the broth, while unsweetened oat milk gives it a softer finish. I am sharing it as a family-kitchen recipe and a personal story, not as a proven treatment for reflux.

What this recipe changes — and what it cannot promise

Traditional chowders often use cream or other rich ingredients. This version uses vegetable broth, blended potato and oat milk instead. That is a cooking choice for texture and dairy avoidance; it does not prove that the dish will prevent heartburn or that it suits every person managing gastro-oesophageal reflux disease (GERD).

The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) notes that foods and drinks commonly linked to symptoms include high-fat foods, tomatoes and other acidic foods, chocolate, caffeine, alcohol, mint and spicy foods — but not everyone has the same triggers. Use your own experience and medical guidance rather than treating any single ingredient list as universally safe.

Ingredients and thoughtful swaps

• Cod or haddock: The recipe uses 1.5 lb (about 680 g) cut into bite-sized pieces. Choose fresh or properly thawed fish and cook it thoroughly.
• Low-sodium vegetable broth: Four cups provide the soup base. Check the label for ingredients you avoid and choose the sodium level that suits your own dietary needs.
• Potatoes: One pound, peeled and diced. Blend a portion with broth to thicken the soup without cream.
• Unsweetened oat milk: One and a half cups, stirred in towards the end. Use a product that suits your dietary requirements; “dairy-free” does not guarantee symptom-free.
• Carrots and celery: Two medium carrots and two celery stalks add texture. Dice them evenly so they soften at a similar rate.
• Onion and white pepper: These are optional. Leave them out if they are personal triggers; the recipe will still work, though the flavour will be different.
• Dill, thyme and bay leaf: Add a gentle herbal flavour. Remove the bay leaf before serving.

My bicarbonate-of-soda experience — not a recommendation

When reflux was especially troublesome, I sometimes used a teaspoon of bicarbonate of soda dissolved in a glass of water. It was inexpensive and easy to find, and I remember feeling that it worked quickly for me. That is my personal recollection, not evidence that it is the right choice for someone else, and I do not recommend that readers copy the amount I used.

Sodium bicarbonate is sold as an antacid, but it is not risk-free. MedlinePlus warns that it increases sodium in the body, can interact with medicines, and requires medical discussion for people with high blood pressure, heart failure, kidney disease or a sodium-restricted diet. Directions vary by product, so a kitchen remedy should not replace the label for an actual medicine. Ask a pharmacist or healthcare professional before using it, especially if you take other medicines, have a long-term condition, are pregnant or breastfeeding, or are considering using it repeatedly. Do not use it for longer than two weeks unless a clinician directs you to do so.

I am including this because it is part of my experience, not because it belongs in the recipe. For recurring reflux, professional advice is a better route than repeatedly reaching for a home remedy. The NHS heartburn and acid reflux guidance explains when a pharmacist or GP can help.

A few cooking details before you start

Cut the fish into pieces of similar size, soften the vegetables before adding the broth, and wait until the potatoes are tender before blending a small portion. Blend hot liquid carefully and return the potato mixture to the pot before adding the fish; this helps keep the fish pieces intact.

Fish can finish cooking at different speeds depending on thickness. FoodSafety.gov recommends cooking fish to 145°F (63°C), or until it is opaque and separates easily with a fork. Use a thermometer when possible instead of relying on minutes alone.

Dairy-free fish chowder

A creamy chowder made with white fish, vegetables and potato-thickened broth. It is dairy-free, but it is not a medical treatment or a guarantee against reflux symptoms.

Prep: 20 minCook: 30 minTotal: 50 minYield: 4–6 servings

• Dairy-free
• White fish
• Potato-thickened

Ingredients

Fish and broth

• 1.5 lb cod or haddock fillets, cut into bite-sized pieces
• 4 cups low-sodium vegetable broth
• 1 lb potatoes, peeled and diced
• 1.5 cups unsweetened oat milk
• 2 tbsp olive oil

Vegetables

• 2 medium carrots, diced
• 2 celery stalks, diced
• 1 medium sweet onion, finely diced (optional if it is a personal trigger)

Seasoning

• 1/2 tsp sea salt, or to taste
• 1 tsp fresh dill, or 1/2 tsp dried
• 1 tsp fresh thyme, or 1/2 tsp dried
• 1/4 tsp white pepper (optional)
• 1 bay leaf

Step-by-step method

1. 1

   Soften the vegetables

   Heat the olive oil in a large pot over medium heat. Add the carrots, celery and onion if using. Cook for 8–10 minutes, stirring, until softened.

2. 2

   Simmer the potatoes

   Add the vegetable broth, diced potatoes and bay leaf. Bring to a gentle simmer and cook for 10–12 minutes, or until the potatoes are tender.

3. 3

   Thicken the broth

   Carefully remove about 1.5 cups of the cooked potatoes and broth. Blend until smooth, taking care with the hot liquid, then stir the mixture back into the pot.

4. 4

   Cook the fish

   Add the cod or haddock and simmer gently for about 5–7 minutes, depending on the size and thickness of the pieces. Cook the fish to 145°F (63°C), or until opaque and easily separated with a fork.

5. 5

   Finish and serve

   Stir in the oat milk, dill, thyme and optional white pepper. Warm gently for 2–3 minutes without a hard boil. Remove the bay leaf, season with salt to taste and serve.

How to adapt the chowder to your own triggers

There is no single menu that works for everyone with reflux. If you already know that onion or white pepper affects you, omit it. If oat milk does not suit you, choose a suitable alternative you already tolerate, keeping in mind that changing the liquid can change the texture. Check packaged broth and milk alternatives for ingredients you personally avoid.

If symptoms tend to happen at night, NIDDK says that leaving at least three hours between a meal and lying down may help some people. A simple food-and-symptom note can also make patterns easier to discuss with a healthcare professional. Do not stop prescribed medicine or make major dietary changes based on a recipe article.

Storing leftovers

Refrigerate leftovers promptly and use them within 3–4 days. Reheat thoroughly. The potato and oat-milk texture may change as the chowder cools and warms again, so reheat gently and stir. Do not rely on appearance or smell alone to decide whether food stored for too long is safe.

Questions about fish chowder and acid reflux

Is this fish chowder guaranteed to prevent acid reflux?

No. This dairy-free fish chowder avoids heavy cream and uses blended potatoes for texture, but no recipe can guarantee that it will prevent reflux. Food triggers differ between people, so adjust ingredients that you know affect you and seek medical advice for frequent or persistent symptoms.

How do I make chowder creamy without dairy?

Simmer diced potatoes in the broth until tender, blend a portion of the potatoes with some broth until smooth, and stir it back into the pot. Finish with unsweetened oat milk and warm gently. This creates a creamy texture without heavy cream; it does not make the dish suitable for every person with reflux.

Can I leave onion or white pepper out of the recipe?

Yes. Leave out onion, white pepper, or any other ingredient you know triggers your symptoms. The recipe is a starting point, not a medically prescribed diet, and the flavour will change with substitutions.

Can I use bicarbonate of soda in water for acid reflux?

Oliver shares that he used bicarbonate of soda in water as a personal habit, but this article does not recommend copying his amount. Sodium bicarbonate is an antacid with sodium-related cautions and possible medicine interactions. Ask a pharmacist or healthcare professional whether it is appropriate for you, and follow the instructions for the specific medicine rather than using an improvised dose.

How do I know the fish is cooked?

Use a food thermometer and cook fish to 145°F (63°C), or until the flesh is opaque and separates easily with a fork. The time depends on the thickness and size of the pieces, so use the temperature and visual cues rather than the recipe time alone.

When should I get medical advice for heartburn or reflux?

Speak with a healthcare professional if heartburn happens most days, persists despite non-prescription treatment, or comes with trouble swallowing, repeated vomiting, or unexplained weight loss. Seek urgent medical help for chest pain, especially with shortness of breath or pain spreading to the arm or jaw.

A comforting bowl, without a promise it can’t make

This chowder gives you a creamy, dairy-free way to cook white fish with everyday vegetables. The blended potatoes do the thickening, and the oat milk rounds out the broth. For me, the reason to share it is simple: reflux has affected my relationship with food, and I know how useful it can be to have another practical dinner idea.

Use the recipe as a starting point, make choices based on what you know about your own symptoms, and speak with a healthcare professional when reflux is frequent or difficult to manage. The goal here is a useful meal and an honest account of experience — not a substitute for medical care.
