Want to try something a little different for St. Patrick’s Day this year? This low carb casserole has all of the flavors of a classic Reuben sandwich, in a hot delicious main dish casserole.
Layers of cooked cabbage, corned beef, sliced dill pickles, and sauerkraut are covered in melted Swiss cheese, then topped with a creamy Russian dressing. (The pickles are optional, but I love the extra tangy-ness and crunch.)
Bake in a large casserole dish or 9×13” pan for a delicious low carb meal.
Serve hot and drizzle with homemade creamy Russian dressing to serve. I like to kick up the spiciness of the dressing by adding extra Sriracha.
I cook my corned beef in an Instant Pot (70 minutes on high pressure), until tender enough to shred. You can also use leftover cooked corned beef and reduced amounts of the other ingredients to make a smaller sized casserole.
Corned Beef Reuben Casserole with Creamy Russian Dressing
2 Tbs butter
½ head of cabbage, shredded
1 onion, halved and sliced
1 tsp salt
27 oz can or pouch of sauerkraut (see recipe before draining)

Preheat oven to 400°F. Spray a 9×13” baking dish with olive oil spray.

Drain liquid from sauerkraut, reserving 2 Tbs of the liquid to make the Russian dressing. Dice or thinly slice dill pickles.
