Dairy-Free, Wheat-Free Clam Chowder (Whole Foods, MRT-Friendly)

Six months into my MRT/LEAP protocol, there was exactly one thing I kept daydreaming about: a big bowl of clam chowder. The problem is that classic New England clam chowder is built on two of the most common reactive foods I see on MRT panels — dairy and wheat — and after going through my own MRT testing and LEAP protocol, I wasn’t willing to trade six months of hard-won progress for a craving.

So I rebuilt it. This version swaps the heavy cream for coconut milk, ditches the flour-and-butter roux for a light oat flour thickener, and leans on real, whole-food ingredients instead of the canned-soup shortcuts a lot of chowder recipes use. It’s dairy-free, wheat-free, and every ingredient is something I’d actually recommend to a client on an elimination protocol — not just something that happens to fit the rules. If you’re new to this way of eating, my complete guide to MRT testing and the LEAP method walks through how the testing and reintroduction process actually works.

Test, not guess. This recipe is dairy-free and wheat-free, which makes it a safe starting point for most elimination diets — but “safe for most” isn’t the same as “safe for you.” If you haven’t done food sensitivity testing yet, celery, garlic, and coconut are all foods I see show up as reactive on individual MRT panels. #TheHealthyRD

Why I Rebuilt This Chowder From Scratch

Traditional chowder recipes lean on two shortcuts that don’t work on a clean elimination protocol: a butter-and-flour roux for thickness, and heavy cream or half-and-half for richness. Both are easy to swap once you know what you’re doing, but most “dairy-free chowder” recipes online just add coconut milk to the same processed base and call it healthy. I wanted something built from real ingredients top to bottom — a version I’d hand to my own clients.

A few of the swaps that make this version different:

Oat flour instead of wheat flour for the thickener — gentler on digestion for most people and naturally gluten-free when you buy certified gluten-free oats. I go into more detail on why gluten-free grains often out-perform wheat nutritionally in my gluten-free benefits guide.
Full-fat coconut milk instead of cream — more on why below.
Butter or ghee, your choice — ghee is nearly lactose- and casein-free for those who react to dairy protein specifically, though if you’re strictly dairy-free, stick with butter substitute or additional coconut oil. I go deeper into the different reasons dairy causes trouble — lactose, casein, even what the cow was fed — in The Dairy Problem.
Whole potatoes and fresh aromatics instead of a canned soup base, so you control every ingredient and every hidden additive.

The Health Benefits Baked Into This Bowl

Clams are one of the best food sources of zinc you can eat. A single 3-ounce serving delivers a substantial share of your daily zinc needs, which matters more than most people realize — zinc is involved in over 300 enzyme reactions in the body and plays a central role in immune defense. I get into the research on zinc deficiency, immune function, and how to check your own status in my full zinc and immunity post. If you’re recovering from an elimination protocol or just get sick “every time something goes around,” this is a mineral worth paying attention to.

Coconut milk brings more to the table than just a dairy swap. It contains medium-chain triglycerides (MCTs), which are metabolized differently than most fats and provide quick, usable energy without taxing digestion the way some longer-chain fats can. I’ve written before about the fuller picture on coconut and cholesterol, and separately about how coconut’s fatty acids support gut health through short-chain fatty acid production and antimicrobial activity in the gut.

Oat flour keeps this chowder gentle on digestion. For many people working through an elimination protocol, wheat is one of the first foods to go — not just for the gluten, but for the fructans that can drive bloating independent of any gluten sensitivity. Gluten-free oats give you the same thickening power without that baggage.

This chowder also leans on real aromatics — celery, onion, garlic, Italian seasoning, fresh marjoram and Thai basil — instead of processed flavor bases, which keeps it firmly in whole-food territory rather than “technically compliant” territory.

Notes & Substitutions

If you’re avoiding dairy protein specifically rather than lactose, ghee is generally the better tolerated of the two butter options.
Cutting dairy entirely? Don’t forget to plan for calcium. I share exactly how I’ve been closing that gap with a whole-food source in this post on bone & marrow.
No oat flour on hand? Pulse gluten-free rolled oats in a blender or food processor until fine.
If celery or garlic are on your own reactive foods list, this is exactly the kind of substitution question worth bringing to a LEAP consultation rather than guessing on your own.

Frequently Asked Questions

Is clam chowder naturally gluten-free?

No. Traditional clam chowder recipes use a wheat flour and butter roux to thicken the base, which means most versions you’ll find contain gluten. This recipe swaps that roux for gluten-free oat flour, so double-check the label on your oats if you’re avoiding gluten strictly, since oats are often cross-contaminated during processing.

Can I make this chowder dairy-free without ghee?

Yes. Ghee works well for people who tolerate the small amount of dairy protein that remains in it, but if you’re strictly dairy-free, substitute a dairy-free butter alternative or additional coconut oil in place of the butter or ghee.

Does coconut milk make the chowder taste like coconut?

Full-fat coconut milk adds richness rather than a strong coconut flavor once it’s simmered with the clam juice, chicken broth, and aromatics. The Italian seasoning, garlic, and fresh herbs balance it out so the finished chowder still tastes like classic clam chowder.

Is this recipe safe for an MRT/LEAP elimination diet?

This recipe is dairy-free and wheat-free, which covers two of the most commonly reactive foods I see on MRT panels, but “safe for most” isn’t the same as “safe for you.” Celery, garlic, and coconut can also show up as reactive foods on individual MRT results, so check your own personal food list before adding this to your rotation.

What can I use instead of oat flour to thicken clam chowder?

If you don’t have oat flour on hand, pulse gluten-free rolled oats in a blender or food processor until finely ground. This gives you the same thickening power without needing to buy a separate bag of flour.
