Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 15 minutes
• Total Time: 30 minutes
• Servings: 4
• Dietary Type: Low-Carb

Ingredients

• 1 lb sliced deli corned beef (Boar’s Head recommended for quality)
• 4-6 ounces Swiss cheese
• 16 ounces sauerkraut
• 4 tablespoons low-carb thousand island dressing (check labels for sugar content)
• 4 tablespoons sugar-free mayonnaise
• 1 tablespoon dill relish (or 1 tablespoon Splenda-sweetened relish)

Equipment Needed

• Large casserole dish
• Mixing bowl

Instructions

1. Preheat your oven to 350°F (175°C). Spray a large casserole dish with non-stick cooking spray (like PAM). This will prevent the casserole from sticking and make cleanup easier.
2. Begin layering the sliced corned beef in the prepared casserole dish. Avoid creating a solid, uniform layer. Instead, scrunch the slices up a bit and distribute them unevenly across the bottom of the dish. This ensures even cooking and prevents the corned beef from becoming tough. Thinly sliced corned beef works best here; chipped corned beef is not recommended as it can become dry during baking.
3. Drain the sauerkraut, removing about half of its juice. If you prefer a sweeter sauerkraut, thoroughly rinse the canned or jarred sauerkraut to remove the brine, then replace it with a bit of cool water. Before adding the sauerkraut to the casserole dish, toss it with 1/2 teaspoon of Brown Sugar Twin or Splenda (optional).
4. Spread the drained sauerkraut evenly over the layer of corned beef. Make sure the sauerkraut is distributed so that it doesn’t clump in one area.
5. Top the sauerkraut with a layer of Swiss cheese. The amount of cheese you use will depend on your personal preference. Ensure the sauerkraut layer is well covered to get a good cheesy melt.
6. Bake in the preheated oven for 15 minutes, or until the cheese is melted and bubbly, but not overly liquid. Monitor the casserole closely to prevent the cheese from burning.
7. While the casserole is baking, prepare the dressing. In a separate mixing bowl, combine the low-carb thousand island dressing, sugar-free mayonnaise, and dill relish (or Splenda-sweetened relish). Mix well until all ingredients are thoroughly combined.
8. Remove the casserole dish from the oven. Let it rest for a minute or two before slicing.
9. Slice the casserole into 4 serving-size squares. Top each serving with a dollop of the dressing mixture. Serve immediately and enjoy!

Expert Tips & Tricks

• Corned Beef Selection: Opt for high-quality corned beef, like Boar’s Head, for the best flavor and texture. Thinner slices work best in this casserole.
• Sauerkraut Sweetness: Adjust the sweetness of the sauerkraut to your liking. If you prefer a less sweet flavor, skip the artificial sweetener.
• Cheese Control: Keep a close eye on the cheese during baking. You want it melted and bubbly, but not burnt or overly liquid.
• Make-Ahead Option: You can assemble the casserole ahead of time and store it in the refrigerator until you’re ready to bake it. This is a great option for busy weeknights.
• Dressing Adjustment: Customize the dressing to your taste by adding a dash of hot sauce or a pinch of smoked paprika.
• Even Browning: If your oven tends to brown unevenly, rotate the casserole dish halfway through baking.

Serving & Storage Suggestions

Serve the Low-Carb Reuben Casserole immediately while it’s hot and the cheese is melted. A side of steamed green beans or a crisp salad complements the rich flavors of the casserole.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, microwave individual portions until heated through. You can also reheat the casserole in the oven at 350°F (175°C) for about 10-15 minutes, or until warmed. Freezing is not recommended, as the sauerkraut and cheese can change texture upon thawing.
