creamy summer squash and cauliflower soup with dill

I love soups when the flavors sound strange together but come out beautifully. Summer squash? Sure. Cauliflower? Sure. But together? I decided I wanted to continue to lower my histamine levels while also having something low carb and filling – soup it is.

You do not need to be on a low histamine diet to stick to these ingredients; this soup works regardless. Though, lowering your histamine levels in your ”bucket” every so often can only help your liver function better, you’ll feel lighter and be less bothered by the usual suspects: pollen, pets, dust, etc

You Will Need:

  • Summer Squash (yellow squash – Depending on how many people you are feeding, I measure 1 large / 2 medium squash per 1 bag of frozen cauliflower florets per 3 people)
  • Cauliflower (I buy the frozen florets but you can buy a whole cauliflower and chop it down if you’d like: chose your level of convenience)
  • Sea Salt / Pink Himalayan Salt / Smoked Sea Salt (preferred)
  • Black Pepper (if you can tolerate)
  • White Onion (or sweet / yellow onion if you can tolerate those types of onion – 1/3 an onion per 3 people)
  • Garlic – Optional
  • Half and Half – Optional (organic will have basic ingredients; you need to stay away from preservatives when lowering histamines. Heavy Whipping Cream – or cashews if you can tolerate – white or yellow potatoes would also work to thicken it up) – Cauliflower will also give a creamy consistency so you can omit the cream and cashews all together
  • Dried Dill and Fresh Dill (fresh is Optional)

I line a large baking sheet with parchment paper and plop my bag of frozen cauliflower florets onto it. Then, I take the medium / large sized summer squash and I peel them. Cutting them down to equal sized pieces I throw them on the baking sheet as well. Depending on how many people you are feeding, I measure 1 large / 2 medium squash per 1 bag of frozen cauliflower florets per 3 people. Taking the onion, cut it in a third and place that on the sheet too (1/3 an onion per 3 people – I cut my third of an onion into halves so the flesh is more exposed to the heating elements; I think it roasts better).

If you’d like to add your garlic to roast now would be a good time. Take advantage and roast a few more than you’re using. They will keep in a concealed container in the fridge for up to 10 days. I use one clove per run through the blender (for one bag of cauliflower and four medium / large squash I used two cloves total – use more if you’d like).

Place it all on the baking sheet and drizzle with olive oil. Stir a bit.

Cook on 400 for 40 minutes.

When done, everything should have shrunk down and would be smelling delicious. You can now kind of see how this makes sense and will come together.

Take your blender, food processor or pot to use an emersion blender in and place your veggies and water (depending on how many people you’re feeding). Add your chicken broth instead of water if you chose that. Add your salt – starting small so you can always add. You can’t take salt away so… always start conservatively. Add a half a cup of the half and half (optional, can sub with cashews). Sounds like a lot but, it’s for the entire pot of veggies. One tablespoon of dried dill. Blend.

If you’re using the Philips Soup Machine, divvy up the ingredients adding as much salt and dill as you prefer. You can always wait to add everything to one pot and add at the end. If you’d like my exact measurements: Half Teaspoon of Smoked Sea Salt, 1 Teaspoon of Dried Dill per Philips Soup Machine.


See if you want to add more salt. If you can tolerate pepper, you may want to add it now and blend again – otherwise I added just the smallest amount at the end as pepper rates a 1 on the SIGHI Scale (the “bible” of histamine ranking food lists) and should only be added when you have your histamine levels down a bit.

This will take just a moment to blend and when you’re ready to serve, top with some of the oil still on your parchment paper from earlier (now infused with roasted veggies) and some dill.

I found that it thickened even more as it stayed in the fridge. I believe with these ingredients it can be left in the fridge for up to 24 hours (if low histamine, otherwise can stay for multiple days). If you want to stay on the safe side, go ahead and freeze batches of the soup in either freezer bags or silicone trays like these here.

The dishes are from Royal Worchester. The silverware is Napoleon Bee.

    Sounds yummy and couldn’t be easier to make. I would be tempted to add to the top of soup just before serving, some crumbled bacon pieces . Who doesn’t love bacon?
