Enjoy a good casserole but not so much the carbs and gluten? Are you looking for a casserole recipe that is gluten-free and keto-friendly? It’s no secret I’m a recipe creator and, honestly, I think I’ve outdone myself. This simple Air Fryer Keto Reuben Casserole is so tasty and easy to make that you’ll never realize that it’s actually a healthier alternative to your favorite casserole dishes!

While I’m ecstatic over the fact that this recipe is soy-free, what I really enjoy about it is that it takes literally just 5 ingredients to make happen. The fewer ingredients, the more likely I am to actually make a recipe. Anyone else like that? 
(If you’re new to the Air Fryer world, check out this post teaching you all about this magic gadget!) 
While the Reuben is a classic dish that is popular especially around St. Patty’s Day, it’s a super simple dish to create any time of year. My husband and my boys are huge fans of this dish. It has become quite the staple recipe in our home and I must agree with them!
Just as I’ve done with all my recipes, I like to research the history of a dish. I find that I am more inclined to honor the traditions of that region as I continue creating recipes inspired by various cultures around the world. Call me weird, but I guess that’s how I’m wired. Either way, I enjoy passing my research onto you! 

Is a Reuben Irish?

Makes sense, right? Since we make Corned Beef around this time of year, it only makes sense that this is an Irish dish, right? Well, it’s not Irish. It was actually invented here in the United States by a German immigrant, Arnold Reuben. He sold the hot sandwiches from his deli in New York City and it didn’t take long before the classic sandwich spread across the United States and the rest of the world.  

What is the difference between corned beef and pastrami?

A lot of people actually think that the two types of meat are the same, but there are pretty big differences between them. Even though they are both cured and have quite a few ingredients to them, the big difference is that corned beef is boiled while the pastrami meat is smoked. And if you eat the two together, you’ll notice a huge difference in how they taste. 

What part of the cow is corned beef?

Corned beef comes from the brisket, which is a relatively inexpensive cut of meat. This is probably why it was popular among the poor and the immigrants.   

Do they eat corned beef in Ireland?

Can you believe that Corned Beef is actually something that we’ve Americanized? While we consider it to be a traditional Irish dish, it’s actually not. In fact, true Irish meals are made with lamb and bacon. 

However, now that tourism is popular around the world, you just might be able to go to Ireland and order corned beef as your main meal.

Can you eat corned beef cold?

Of course! In fact, this is probably one of my favorite leftover meals! The key is to make certain that it’s cooked properly first and brought to the proper internal temperature to ensure that it’s done.

Then, the next day when you’re ready for lunch, all you have to do is pull it out of the fridge and dig in! 

What temperature do you cook corned beef to?

Even though the Air Fryer is doing all the cooking for this recipe, it’s still important to get the right internal temperature for your corned beef. To be on the safe side, corned beef should be cooked internally to 145 degrees. 

The easiest way to make certain that the internal temperature is correct is to use a meat thermometer. 

Can you freeze cooked corned beef?

You can! This is just another reason why I really like this recipe! If you happen to have any leftover, just simply store it properly in freezer bags or air-tight storage containers and save it for later. You can easily reheat it in your oven or Air Fryer and have the same delicious meal one more time. 

If you freeze the entire casserole once cooked, just know that the texture and taste might be a little bit different once unthawed. Personally, I don’t recommend freezing it for that specific reason – texture and taste. But, it’s also an option if you decide to keep it for next week’s meal plan.  

Enough of this chit-chat. Let’s dig into the recipe, shall we?

Since this Reuben recipe is simple and easy to make, there really isn’t a lot of meal prepping ahead of time. The biggest concern you’ll have is making certain that you have all your ingredients on hand to get started.
