About this recipe
Quick Prep: even if you don't buy precut butternut squash, this is an incredibly quick recipe to prep; if you're unsure about canned coconut milks, you can also buy pure coconut milk powder to make your own at home.
Easy Vegan Main: full of flavor and free of meat, this soup makes for a great vegan low histamine dinner, especially if you add hemp seeds or protein powder.
Low Histamine Soup: so many readers have asked about low histamine soups, so this low histamine butternut squash soup is yet another squash-based answer to that request.
Ingredients
Butternut Squash: what's a low histamine squash soup without the star of the show? This bright orange vegetable is a rich source of vitamins and minerals, and sweetens up beautifully in the oven. Much like my squash & tahini soup, this recipe takes advantage of that delicious caramelization.
Raw Garlic: just like an onion, using raw garlic adds an umami element to the soup that really complements meats and root vegetables as a side dish.
Coconut Milk and/or Vegetable Stock: either or both of these are used to thin out your soup. I know I like my soups thicker than most people, so you may need more liquid than I use, but start with 2 cups.
How to make 3 ingredient butternut squash soup: step-by-step instructions
Step 1. Preheat oven to 400°F (205°C).
Step 2. Cut the garlic in half, and peel & chop your squash into cubes; it will get soft after a couple minutes in the microwave, if you're having trouble peeling it. You can also put it in the preheating oven to dry it off before tossing it in the oil.
Step 3. Toss your squash & garlic with the oil & salt, and then arrange in a single layer on a baking tray lined with foil or a silicone baking sheet (use 2 trays if needed).
Step 4. Bake for 25-30 minutes on convection mode, until the squash is starting to brown.
Step 5. Allow the squash to cool for a few minutes, then combine everything in a large pot and use an immersion blender to smooth all the ingredients. Alternately, add it to a high-powered blender with half the liquid, and blend well for 15-20 seconds, then pour in the rest of the broth or milk and finish blending. Serve with a sprinkle of sesame seeds or nigella seeds, and a dollop of coconut cream or sour cream.
Recipe notes & tips
Seasonings: You can use any type of seasoning on the squash to add even more flavor, but only add them when you’re tossing the squash cubes, otherwise the final soup may not taste right.
Adding Meat: You could certainly add meat to this dish, if desired; I'd add no more than a half-pound (225g) of cooked meat total.
Freezing & Storage: To freeze this 3 ingredient soup, portion it into air-tight containers and keep for up to six months, reheating for a few minutes over medium-low heat on the stovetop.

Hello! Thank you so much for all of this information. I’ve a question about squash. Why is butternut ok and pumpkin isn’t? I grow my own squash and I’m hoping they are low histamine. They’ve been curing for about three months now. The varieties are crown prince (orange flesh) and white mashed potato (white flesh). Thanks again for everything.
Max says
No problem, Jean! Pumpkin is another somewhat controvertial one, like cinnamon, and from my research it seems to come down to the fact that pumpkin is markedly higher in protein than are the other varieties of winter squash (the protein/amino histaidine degrades into histamine over time). So I err on the side of 'give it a try, but not at the beginning,' much like cinnamon and even small amount of lemon and lime juice, which tend ot be fine after an initial calm-down period (and make lots of dishes taste complete!). So personally I'd give pumpkin a try in your situation, if the other squashes I'd grown worked well for me, as I did the exact same thing in the fall as my meager first harvest of squashes came up and were ready for eating.
Jean says
Ah, you’re a squash grower too? They’ve are my fav. Easy to grow and available all winter. Not to mention yummy. Thanks again for your help on this question and your website in general. I’m on day 4 of your 5 day plan and can tell an improvement already. Relief to have some answers (and some relief!).
Max says
Yes, and definitely yummy! I've been growing as of last year, when I first started with zucchini, plus delicatas and butternuts, as well as what ended up being exactly one very small sugar pumpkin for my mom. It was a big learning experience, ha. My pleasure to be of help, and I'm very glad to hear that you're feeling better - I hope it only continues!
Monica Safreed says
Can I use sweet potatoes instead of the butternut? Can the potatoes bake in a regular/non convection oven ? Can I use an electric hand blender if I don’t have an immersion blender?
Thank you 😊
Max says
Yes! You could absolutely use sweet potatoes instead of squash, and yes, you can bake them in a regular oven (though keep an eye on them - sweet potatoes bake a bit faster than squash, though in a regular oven they won't bake AS quickly. However I would use a regular blender (or even a food processor + some water/coconut milk) over using a hand blender, as it won't have as much immersive power as an immersion blender.
