The ultimate keto comfort food.

Comfort food. The very words bring a smile to my face. While decadent desserts and fancy flavor laden treats definitly fall into that category. I am specifically refering to the warm-your-tummy, kiss-your-mummy, down-home, feel-good delectable dinner stuffs that typical southern cooking is famous for. 

Alas, it has been many moons since I was able to enjoy such culinary nostalgia with impunity. Food allergies and sensitivies have firmly placed most of the basic ingredients to found in southern cooks pantry in the off- limits category.  

Can keto comfort food really be allergen free?

So what is a hungry, determined and allergic country chef to do? Improvise! Keto-fy it! The ground rules for any tasty casserole is for there to be the perfect balance of taste and texture. Enough flavor to keep your taste buds excited, enough texture otherwise it would just be flavorful soup. Which isn’t a bad thing if that’s what you are going for, but we want a dish that you can eat with a fork here so we need substance. 

I am allergic to dairy so that means subbing the cheese out for a vegan alternative. I have tried a few different brands with this recipe and most do a passable job, but I keep coming back to Violife Just Like mozzarella shreds. It melts, it stretches, and it really does taste “just like” mozzarella.

If you happen to be one of those poor souls allergic to eggs, my suggestion for possible substitutions are, vegan mayo, vegan plain yogurt maybe along with some xanthan gum to help bind it together. Pre-made egg substitute such as Bob’s Red Mill Egg Replacer might work as well. I haven’t experimented with these options though.

Which bear-I mean pan, is best?

I opted to use my cast iron pan all the way through this recipe, from browning to baking. One pan to cook in, one pan to clean. Simplicity is beautiful. That being said, if you don’t happen to be the proud owner of one of these beauties, a glass casserole dish will do fine for the baking portion.

Just an aside here, if you don’t own a cast iron pan, consider investing in one. Yes, they are a bit more maintenance than your average stainless steel variety, but they will take your culinary game to the next level. They can do almost anything and as long as you take good care of it, you will have it for life. 

So back to the recipe attempt at hand. Will it work?! Can it succeed?! Will it…comfort? There’s only one way to find out. 

Browning the beef
Hmm…something yummy this way comes.

And the comfort food of the year award goes to…

Spoiler alert: It turned out amazing. It was thick, cheesy, meaty, tangy and salty. It hit the spot. Since making it the first time my hubby has declared it his all time favorite and has requested it be added to our regular dinner rotation, and since it is easy peasy as pie to make I happily oblige!

The yummy finale. Keto beef sauerkraut casserole.
Voila! Keto dairy free beef sauerkraut casserole in all it’s messy yummy glory!

If you are in need of some comfort food that also fits your dietary needs then I hope this ticks all your boxes. Happy cooking!
