Keto Cauliflower Mash Cottage Pie


keto cottage pie


The latest craze for mashed potatoes is to substitute it for Keto cauliflower mash and I’m telling you that it is so good we no longer buy potatoes.

Pair your cauliflowe mash with miced beef, chicken, lamb or turkey along with spices and you’ve got yourself one heck of a keto recipe.

What is cauliflower mash?

Cauliflower mash is a buttery, creamy and delicious side-dish comparable to mashed potatoes that even picky eaters can’t even tell the difference.

Another substitute for potaotes in the keto world is radishes. If you haven’t tried our Keto Radish Potato Salad, it’s a must especially for summer bbq’s and picnics.

Since cauliflower has reduced in price from over $6 a head to a reasonable $2.99 each it’s worth creating keto recipes with it.

I know some people also use frozen cauliflower which you may even find cheaper in the frozen section at the grocery store.

One of my favourite cauliflower recipes is my baked cauliflower with cheese as a side dish to roast beef or any other protein.

How To Make Keto Cauliflower Mash

Creating cauliflower mash is very easy so don’t let any of the many names fool you as they are all the same thing:

  • Smashed cauliflower
  • Mashed cauliflower
  • Cauliflower puree
  • Cauliflower mashed potatoes (there is nothing potato about this recipe but some people need to call it mashed potatoes to help describe what it is that you will be eating).

How to Prepare Cauliflower

How long should you boil the cauliflower?

I make sure to chop my cauliflower into small florets so they cook faster and it’s easier to mash as well. 

The key is to keeping the cooking time down to around 20 minutes is to boil it on high heat but be cautious it doesn’t boil over.

I use the wooden stick method and set it across the pot to keep it from boiling over. It really does work, try it.

Here’s a quick tip for you:

I used to go a bit mad trying to cut into a cauliflower but I no longer fear this round bouquet of florets because I simply smash the cauliflower on the cutting board.

Each time I hit it more and more of the cauliflower falls apart which makes for a simple chop fest.

To get the cauliflower started:

I fill a pot of salted water and add the cauliflower to the cold water and then bring it to a boil.

Once the cauliflower is fork tender I drain the water and put the pot back on the hotplate while it’s still has heat to dry up some moisture.

Cauliflower is naturally watery so it will be tough to get rid of all the moisture but it helps to make a thicker cauliflower mash.

What is fennel?

Several cultivars of Florence fennel are also known by several other names, notably the Italian name finocchio.

In North American supermarkets, it is often mislabeled as “anise”.

What are fennel greens?

These are the greens at the top of the fennel that look like dill and can be used in cooking and even to make flavoured tea.

I used the greens as flavouring in the cauliflower mash and sliced some of the fennel bulb to use in place of traditional celery.

How can you use fennel greens?

The bulb, foliage, and seeds of the fennel plant are used in many of the culinary traditions of the world. The small flowers of wild fennel (known as fennel “pollen”) are the most potent form of fennel, but also the most expensive.

Dried fennel seed is an aromatic, anise-flavored spice, brown or green in color when fresh, slowly turning a dull grey as the seed ages. For cooking, green seeds are optimal. The leaves are delicately flavored and similar in shape to those of dill.

The bulb is a crisp vegetable that can be sautéed, stewed, braised, grilled, or eaten raw. Young tender leaves are used for garnishes, as a salad, to add flavor to salads, to flavor sauces to be served with puddings, and also in soups and fish sauce.

Fennel seeds are sometimes confused with those of anise, which are similar in taste and appearance, though smaller.

Fennel is also used as a flavoring in some natural toothpastes. The seeds are used in cookery and sweet desserts. (source) Wikipedia- Fennel where you can read more about fennel and it’s uses.

Keto Cauliflower Mash Cottage Pie Tips

To the boiled cauliflower I add a pinch of salt, fresh cracked black pepper, 2 tablespoons of butter, 2 tablespoons of cream cheese, 1/2 cup of fennel greens (the leafy greens at the top of the fennel if your store did not cut them off) and a swish of cream and then I mash.

Keto Cauliflower mash is simply delicious and perfect for this cauliflower mash cottage pie recipe.

Once the mash is done it’s time to get going on the cottage pie mince filling which is also very easy to make.

In a skillet add a tablespoon or two of butter to melt on medium heat. Once melted add the minced onions, radishes and fennel.

You can add chopped mushrooms or any other vegetables you like as long as they are low carb or fall with-in your macros for the day.

If you’re not worried about low carb add whatever vegetables you like.

If you think that radishes sound disgusting in the cauliflower mash cottage pie don’t be.

They taste just like boiled potatoes once the cottage pie is cooked and ready to eat. Even I was skeptical but it’s true…you’ll see!

Once the vegetables are coated in butter and starting to cook up a bit I add in a tablespoon of tomato puree, 1/2 cup of beef broth, 1 cup of fennel greens chopped, all spices and one pound of Angus minced beef.

Once this cooks up you will be ready to put your cauliflower mash cottage pie together.

I used a 9×11 white baking dish which I sprayed with cooking spray and added in the cottage pie mixture to the bottom of the dish.

I then topped it with cauliflower mash and 3 strips of thick slicked cooked bacon to boost the flavour.

Wrap the Keto cauliflower mash cottage pie in tin foil then bake in the oven for 1 hour at 350 degrees.

Remove from the oven and top with a cup of mozzarella and old cheddar cheese but you can use your favourite cheeses.

Put the backing dish back into the oven on broil for 5 minutes until the top is golden brown and bubbly.

I like to let the cauliflower mash cottage pie sit for at least 30 minutes so it can cool down which makes it easier to cut and serve.

If you serve it straight from the oven you’ll never get a perfect piece and it will just be a mushy mess again because of the moisture content.

I’d still eat it but it’s not that appealing when serving this to guests but totally fine.

How to make homemade keto beef gravy

The cauliflower will give off lots of moisture so you will have lots of gravy broth underneath once you take the first piece out.

If you want to make homemade keto gravy just throw two beef bouillon cubes or 2-3 tablespoons of your favourite beef bone broth cubes or powder in 1.5 cups of water and bring to a boil.

In a snall bowl add 1 teaspoon of xanthan gum to hot water and stir to get any lumps out.

Add the xanthan gum mixture to the beef broth and stir until it thickens followed by salt, pepper and any other spices.

Voila, you have keto beef gravy.

That’s how easy it is to make cauliflower mash cottage pie for dinner with a simple keto beef gravy.

It takes about 1.5 hours from start to finish so you can easily make this after work and still have it on the table for dinner.
