Why You'll Love This Recipe

The combination of tender sauerkraut, savory cubed corned beef, and a rich, melted Swiss cheese topping is nothing short of magical. The sauerkraut softens beautifully during cooking, losing its sharpness while keeping that signature tangy depth that pairs so perfectly with the salty, meaty corned beef. The cheese melts into every nook and cranny, creating a creamy, gooey layer on top that is absolutely irresistible.

Ingredients

• 2 cups cooked corned beef, cut into bite-sized cubes
• 2 cups sauerkraut, drained and lightly rinsed
• 1 can (10.5 oz) cream of mushroom soup
• 1/2 cup sour cream
• 1/2 cup mayonnaise
• 1 teaspoon Dijon mustard
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1/4 teaspoon black pepper
• 1 1/2 cups shredded Swiss cheese (or a blend of Swiss and Gruyère)
• Fresh chopped chives or parsley for garnish
• Crusty rolls or rye bread for serving

Method

1. Preheat your oven to 350°F (175°C) if baking, or set your slow cooker to the low setting if using a crockpot.
2. In a large mixing bowl, combine the cream of mushroom soup, sour cream, mayonnaise, Dijon mustard, garlic powder, onion powder, and black pepper. Stir until everything is well blended and smooth.
3. Add the drained sauerkraut to the creamy mixture and stir to coat it evenly.
4. Fold in the cubed corned beef gently so the pieces stay intact.
5. Transfer the mixture into a greased casserole dish or directly into your slow cooker insert.
6. Sprinkle the shredded Swiss cheese generously and evenly over the top of the mixture.
7. If baking in the oven, cover with foil and bake for 25 minutes, then remove the foil and bake for an additional 10 to 15 minutes until the cheese is melted, bubbly, and lightly golden on top.
8. If using a slow cooker, cook on low for 3 to 4 hours or on high for 1.5 to 2 hours, until everything is heated through and the cheese has fully melted.
9. Remove from heat and let it rest for 5 minutes before serving.
10. Garnish with freshly chopped chives or parsley and serve hot alongside crusty rolls or rye bread for scooping.

Tips for the Best Results

If you prefer a thicker, richer casserole, reduce the amount of sauerkraut liquid by pressing it firmly before adding it to the mix. For extra depth of flavor, try using a smoked corned beef or adding a splash of Worcestershire sauce to the creamy base. Gruyère cheese can be swapped in for a nuttier, more complex flavor profile. Leftovers reheat beautifully the next day and arguably taste even better once all the flavors have had time to meld together overnight.

Serving Suggestions

This casserole is a complete meal on its own, but it shines brightest when served alongside warm, crusty bread rolls for dipping and scooping up all that creamy, cheesy goodness. A simple green salad on the side adds a fresh contrast to the richness of the dish. For those who love a little heat, a drizzle of hot sauce or a dollop of spicy mustard on the side takes things to the next level.
