Ingredients You’ll Need
For the Casserole Base:

- 2 cups chopped or shredded corned beef (leftover or deli-sliced)
- 1 (14 oz) can sauerkraut, drained and squeezed dry
- 1 ½ cups shredded Swiss cheese
- ½ cup Thousand Island dressing (plus extra for drizzling)
- ¼ cup chopped dill pickles (optional, for extra tang)
For the Egg Mixture (Binds Everything Together):
- 4 large eggs
- 1 cup milk (or half-and-half for richness)
- 1 tsp caraway seeds (optional, for authentic rye flavor)
- ½ tsp garlic powder
- ¼ tsp black pepper
For Topping:
- ½ cup additional shredded Swiss cheese
- 2 tbsp butter, melted
- ½ cup crushed rye crackers or breadcrumbs (for crunch)
Step-by-Step Instructions
1. Prep the Bread & Layers
- Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish.
- Spread rye bread cubes evenly in the dish.
- Layer on corned beef, sauerkraut, pickles (if using), and 1 ½ cups Swiss cheese.
- Drizzle with ½ cup Thousand Island dressing.
2. Make the Egg Mixture
- In a bowl, whisk together eggs, milk, caraway seeds, garlic powder, and pepper.
- Pour evenly over the casserole. Press down gently to help bread absorb liquid.
3. Add the Topping & Bake
- Sprinkle with remaining ½ cup Swiss cheese.
- Mix melted butter and crushed rye crackers, then scatter over the top.
- Bake for 35-40 minutes until golden and set in the center.
- Let cool 5 minutes, then drizzle with extra Thousand Island dressing.
Pro Tip: For extra crispiness, broil for the last 2-3 minutes (watch closely!).
