Cauliflower Mash

Low Histamine Cauliflower Mash with Kale: Colcannon Inspired (also Low Oxalate, Low Lectin)

This low histamine cauliflower mash with kale was inspired by a traditional Irish dish called colcannon. 

Are you following a low histamine diet AND looking for low oxalate and low lectin recipes, too? If so, this take on mashed potatoes might be just the thing. 

Colcannon is typically mashed potatoes mixed with a leafy green like cabbage or kale.  

It also uses ingredients like milk, butter, and onions (or leeks). 

In general, most colcannon recipes are low histamine. 

However, potatoes aren’t low lectin or low oxalate. And you might be holding off on dairy if you are in Phase 1 of the low histamine diet and haven’t done the Dairy Zoomer yet. 

This tasty and healthy side dish is great at any time of year. But it’s especially nice on cool nights when you want to warm up with comfort food.

Low Histamine Cauliflower Mash with Kale 

Before you change your diet on your own, please make sure you’re working with a healthcare practitioner who can help you with this. Never limit foods unnecessarily, and always have a licensed medical provider who is supervising your case.  

You might have heard of cauliflower mash or mashed cauliflower.  

Its lower carbohydrate content made it popular with the keto diet or generally with anyone watching their carb intake.  

Additionally, cauliflower is a great source of vitamins and other nutrients that support your body. 

Next, let’s get a quick overview of the benefits of the two main ingredients in this dish, cauliflower and kale.  

Cauliflower 

Cauliflower is a powerhouse of vitamin C.  

Just one cup of cauliflower has about 75% of the daily recommended value of vitamin C. For comparison, that’s almost as much vitamin C as one medium orange has.  

Oranges are known to be a rich source of vitamin c, but citrus can be a histamine liberator. So, consider adding cauliflower to your meal plans to get a boost of vitamin C. 

Vitamin C has benefits including: 

  • Needed for production of:
    • Collagen 
    • Amino acids used in energy production  
    • Some neurotransmitters 
  • Plays a role in protein metabolism 
  • Plays a role in wound healing 
  • Has antioxidant properties 
  • Aids in immune function  
  • Improves the absorption of nonheme iron 

You may be surprised that cauliflower is also a good plant-based source of vitamin B6.  

Many people think of meat when they think of ways to get B6 from their food. And it’s true that meat contains a good amount of B6! 

But plant-based foods can provide some B6, too. 

Regardless of how you get your B6, be sure you are getting enough.  

Some people have low diamine oxidase (DAO) levels because of nutritional deficiencies, including B6 deficiency. 

DAO is one of the histamine degrading enzymes your body produces. Very important, especially if you have Histamine Intolerance.

One cup of cauliflower has .184 mg of B6. That doesn’t look like much!  

However, the average recommended daily intake for B6 in women 51+ is about 1.5 mg.

That means that 1 cup of cauliflower is about 12% of your daily need. (RDA for women 19 to 50 is about 1.3 mg.)

Kale 

Colcannon typically uses either cabbage or kale.  

Although, when we asked around, a friend who’s been to Ireland frequently has even had colcannon without either! 

We looked at numerous recipes in cookbooks and online, too. Some have kale, some have cabbage, and some mention that you can add cabbage or kale but don’t give instructions for incorporating them. 

Very interesting indeed! 

We chose to use kale because it added both nutrients and interest to the dish. We chose kale over cabbage because it took less time to cook. (We tried it both ways. We’ll tell you more in the Top Tips section.) 

Admittedly, we chose kale because it was easier. Who doesn’t love an easy side dish? But kale has a lot to offer besides being easy to cook. 

Kale is often referred to as a super food. These are nutrient dense foods, typically vibrant in color. 

Kale is rich in vitamins like: 

All of these are important for the health of your body, especially if you are dealing with Histamine Intolerance or Mast Cell Activation Syndrome (MCAS). 

You already read just a few ways vitamin C and B6 can be beneficial. 

When it comes to Histamine Intolerance or MCAS, here’s a quick look at how these other vitamins can support you. 

Studies have shown that adequate iron can aid in decreased mast cell degranulation. 

Iron is also important for processes including: 

  • DNA synthesis (essential for proper functioning of cells) 
  • Hormone balance
  • Oxygen transport
  • Immune Function

Magnesium has been shown to be helpful with: 

  • Stabilizing mast cells
  • Reducing inflammation
  • Can boost DAO activity

Top Tips for Low Histamine Cauliflower Mash with Kale 

Cauliflower mash may have taken off in popularity due to being low carb. 

Another benefit is that cauliflower mash is easier to make than mashed potatoes. 

Think of the time and energy you save by not having to peel potatoes! 

Another way we simplified was using kale instead of cabbage. Truth told, we tried it both ways. 

You can use cabbage in this recipe. It’s low histamine, low oxalate, low lectin, low FODMAP and low salicylate! 

We chose to provide you with the kale recipe, though. That’s because one taster preferred the kale version because of the taste, and another preferred the kale because of the texture. Everyone is different! 

We liked it both ways, but as we said, we went with kale for the official recipe card because it was easier.  

If you want to use cabbage, here’s what to know. 

Using Cabbage Option (Low Salicylate Modifications) 

If you use cabbage, use your food processor to shred it. 

You’ll get consistent and thin pieces which help it cook to a tender state quicker than thickly cut pieces. 

Still, cabbage took longer to cook than kale. So, do plan a little extra time if you go this route. You’ll want the cabbage VERY tender.  

You can make this recipe low salicylate if you: 

  • Replace 2 Tablespoons of Olive Oil with 2 Tablespoons Ghee
  • Replace ½ cup + 2 Tablespoons Coconut Cream with ½ cup + 2 Tablespoons of Grass Fed Cream or Whole Milk  
  • Replace 2 cups Kale with 2 cups of Cabbage

Plain Cauliflower Mash 

If you want things simpler still, both in taste and preparation, you can make this cauliflower mash plain, meaning you can omit the kale.  

We would recommend keeping the onions and chives, though. Those elements added flavor that we think you’d miss if they are removed. 

Preparing the Cauliflower 

In our preparation, we steamed the cauliflower. 

You can boil the cauliflower if you don’t have a steamer basket.  

But the advantage of steaming is that veggies hold more of their nutrients. Water-soluble vitamins can leach into the boiling water that you discard. 

If you choose to steam the cauliflower, be sure to keep the water below the steamer basket. We filled the bottom of the pot until it was just shy of seeping through the holes in the basket.  

There will be water loss, but ours didn’t even come close to running dry. This is a concern to be aware of if you are steaming anything.

Just keep an eye on yours. Every pot, stove, and basket are different!

Ingredients
  

  • 1 Medium Cauliflower Head 2 pounds, chopped (about 8 cups)
  • 2 Tablespoons Kasandrino’s Olive Oil
  • 1 Tablespoon Fresh Garlic Cloves minced
  • ½ cup Let's Do Organic Coconut Cream plus 2 Tablespoons, divided
  • ½ cup Yellow Onion diced
  • 1 teaspoon Redmond Real Salt divided
  • 2 cups Organic Kale tightly packed and finely chopped
  • 1 teaspoon Fresh Organic Chives

* See notes for low salicylate option swaps

Instructions
 

  • Start by steaming the cauliflower. Add enough water to a large pot so that it comes ever so slightly below the holes in the steamer basket. Bring water to a boil. Add your cauliflower and cover. Steam about 20 minutes or until tender. (There will still be some tooth to it, but it should be fork tender.)
  • Meanwhile, in a small skillet over medium heat, add the olive oil, garlic, and salt and sauté until fragrant, about 1 minute.
  • Add the kale to the garlic and sauté until tender. About 2 minutes. Transfer to a bowl and set aside.
  • In the same skillet, add ½ cup of coconut cream, ½ teaspoon salt, and the onion. Cook over medium heat until onions are tender (about 6 minutes). Remove from heat and set aside.
  • When the cauliflower is tender, thoroughly drain the water and transfer the cauliflower to a food processor along with 2 Tablespoons of coconut cream and remaining ½ teaspoon of salt. Pulse slowly to avoid over-processing. You want a mashed potato-like consistency, not runny. There will be some texture to the cauliflower, it won’t be totally smooth like mashed potatoes.
  • Transfer the mashed cauliflower to a large bowl and stir in the garlic kale mixture as well as the onion mixture. Stir to combine.
  • Top with chives.

Notes

You can make this recipe without the kale for a simple cauliflower mash. 
Low Salicylate Option – you can make this recipe low salicylate if you:
  • Replace 2 Tablespoons of Olive Oil with 2 Tablespoons Ghee
  • Replace ½ cup + 2 Tablespoons Coconut Cream with ½ cup + 2 Tablespoons of Grass Fed Cream or Whole Milk  
  • Replace 2 cups Kale with 2 cups of Cabbage
