Keto Reuben Skillet

Ingredients

Main Skillet:

1 tbsp butter or avocado oil
1/2 small onion, thinly sliced
1/2 lb sliced corned beef (deli style or leftover, chopped)
1 cup sauerkraut, drained
1 cup shredded Swiss cheese
1/2 tsp caraway seeds (optional, for rye-like flavor)
Keto Russian Dressing:
1/4 cup mayonnaise
1 tbsp sugar-free ketchup
1 tsp horseradish (prepared, not creamy)
1/2 tsp Worcestershire sauce
1/4 tsp paprika
Salt and pepper to taste

Instructions

Step 1: Sauté the Onions
Start by heating the butter or oil in a large skillet over medium heat. Add the sliced onion and cook for 5–6 minutes, stirring occasionally, until soft and slightly caramelized.
Step 2: Add Corned Beef and Sauerkraut
Next, add the chopped corned beef and drained sauerkraut to the skillet. Stir to combine and heat through for about 3–4 minutes. If using, sprinkle in the caraway seeds for extra flavor.
Step 3: Prepare the Dressing
While the skillet heats, mix all the dressing ingredients in a small bowl. Taste and adjust seasoning as needed.
Step 4: Add Cheese and Melt
Sprinkle the shredded Swiss cheese evenly over the skillet mixture. Cover the skillet and reduce heat to low. Let the cheese melt for about 2–3 minutes, or until bubbly.
Step 5: Serve
Once the cheese is melted, drizzle the Russian dressing over the top or serve it on the side. Garnish with chopped parsley or dill pickles if desired.

Tips and Variations

Add a Crust
For extra texture, layer a low-carb tortilla or cheese wrap on the bottom of the skillet and crisp it before adding the other ingredients.

Use Pastrami
Switch out corned beef for pastrami if you prefer a smoky flavor.

Make it Spicy
Add a dash of hot sauce or a spoonful of chopped pickled jalapeños to the dressing.

Add Pickles
Chopped dill pickles stirred into the skillet add a classic Reuben crunch.

Eggs on Top
For a breakfast twist, top the skillet with a fried egg.

Why It’s Great for Keto
This skillet avoids all high-carb bread while preserving every ounce of flavor. The corned beef provides protein, the cheese and dressing add healthy fats, and sauerkraut brings tanginess and probiotics. There’s no sugar, no gluten, and no grains—just real ingredients that keep you full and satisfied.

Unlike traditional Reubens, this version keeps your carb count low while still delivering the same hearty, deli-style comfort.

Serve it over a bed of shredded lettuce or cauliflower rice.
Add roasted radishes or keto “rye” crackers on the side.
Turn it into wraps using low-carb tortillas.
Pair with a dill pickle spear or a side of coleslaw for a deli-style plate.
