Can You Have Ketchup On Keto?
Most ketchup is loaded with sugar and is not keto-friendly. There are sugar-free versions, but many of them contain sucralose, which isn't considered a clean ingredient and may lead to sugar cravings in some.
I prefer to make homemade ketchup, but I keep Primal Kitchen on hand for those times when I am short on time.

How to Make Keto Reuben Casserole
This is a visual walkthrough for those that like pictures. See the recipe card below for the complete recipe with measurements.
First, start by preheating your oven and spraying your casserole dish with cooking spray. I like avocado oil, but any oil works here.
Next, combine the mayonnaise, cream cheese, ketchup, horseradish, and smoked paprika in a bowl. Season to taste with salt and pepper.
After that, chop the corned beef and layer half of it on the bottom of the prepped dish. Top with half of the well-drained sauerkraut, chopped pickles, and caraway seeds.
Drizzle with half of the sauce and top with half of the cheese.
Repeat the layers ending with the cheese. Bake for 25 minutes. Turn the heat to broil and cook until the top is browned and bubbling.
