Is ham keto?

So let’s first discuss ham, and whether or not it’s appropriate for the keto diet. The truth is that it depends.

Ham is a cut of pork from the thigh, and it’s usually cured for longer shelf life and preservation. It may or may not be smoked as well. So it really depends on how your ham is treated before you purchase it.

Many commercial hams are cured with a brine of salt and sugar, amongst other additives. Which means that some hams can have up to 4 or 5 grams of carbs per serving, even without the sugary glazes.

It’s important to be a label reader and choose ham with the least amount of carbs. Some can even have 0g, if they are cured with salt brine or simply smoked.

Ham and Cauliflower Casserole Inspiration

My husband’s brother sent us a gorgeous heritage breed ham from Zingerman’s for Easter. Of course, the very first thing I did was flip it over to look at the nutritional information. Phew, only 1g carbs per serving!

I am not a huge ham lover, but this was among the best I’ve ever had. Rich and flavorful, and no sugary sweetness. But as always with ham, it was far too much for one dinner.

We’ve all been picking at it daily, often eating it for breakfast with an egg on top. But I wanted to do something else more interesting with the leftovers. I saw this Ham and Hashbrown casserole on Salty Side Dish, and thought I could do something similar with cauliflower.

How to make Keto Ham Cauliflower Casserole

This is a super easy keto side dish that takes only 6 ingredients. It’s full of flavor and even my kids loved it. Big win!

Shred or coarsely chop the cauliflower

You could make this keto cauliflower casserole with cauliflower rice. But I wanted more texture than that. So I popped the florets in my food processor and pulsed it until coarsely chopped.

You could also use the shredding blade of a food processor. Or you could simply use a sharp knife and chop them by hand.

Dice the ham

You want to get bits of ham in every bite so dicing it works best. The pieces should be no more than ¼ inch to ½ inch in size (small dice).

Grate the cheese

You can use pre-shredded cheese but grating an 8 ounce block of cheddar is easy. And this way, you can be sure that there are no added starches or fillers.

Use a thickener

Unlike hashbrowns, cauliflower releases a lot of water during baking. So I recommend sprinkling in some glucomannan powder before baking. The liquids will thicken up more as the casserole begins to cool.

It’s the same trick I use for Keto Rhubarb Crisp!

If you can’t find glucomannan, xanthan gum may also work. Neither is required, but the casserole will be a little watery when it comes out of the oven.

Bake until bubbly

The casserole is done when the filling is bubbly, the cheese is browned, and the cauliflower is fork tender.

Let stand

This casserole is super hot straight out of the oven. I recommend letting it sit for 10 or 15 minutes before serving. This also gives the filling a chance to thicken up a bit.

That’s it, friends! This keto cauliflower casserole was a surprise hit in my house, with my middle child even coming back for seconds. That says a lot!
