Ingredients Needed

  • 1 medium head cauliflower (cut into bite-sized florets)
  • 3 tbsp (45ml) avocado oil
  • ½ tsp sea salt
  • ¼ tsp black pepper
  • 1 can (14oz / 400g) sauerkraut, drained
  • 1 cup (240ml) sugar-free thousand island dressing
  • 1 lb (450g) corned beef, chopped into bite-sized pieces
  • 8 oz (225g) Swiss cheese slices

How To Make Low Carb Reuben Casserole

  1. Preheat the oven: Set the oven to 400°F (200°C).
  2. Prepare the cauliflower: In a large bowl, toss the cauliflower with avocado oil, salt, and black pepper.
  3. Roast the cauliflower: Spread the cauliflower in a single layer on a baking sheet and roast for 25-30 minutes until tender and lightly browned.
  4. Assemble the casserole: Transfer the roasted cauliflower to a 9×13 inch (23x33cm) baking dish. Spread the drained sauerkraut on top, drizzle with thousand island dressing, then add the chopped corned beef. Cover with Swiss cheese slices.
  5. Bake: Place the dish in the oven for 10-15 minutes until heated through and the cheese is melted.

Recipe Tips

  • Roast the cauliflower well: Make sure the cauliflower is golden and slightly crispy before adding it to the casserole. This keeps it from getting soggy.
  • Drain the sauerkraut properly: Too much liquid will make the casserole watery. Squeeze out as much moisture as possible before adding it.
  • Use quality corned beef: Freshly sliced corned beef from the deli has better texture and flavor than pre-packaged versions.
  • Melt the cheese perfectly: For the best melt, use thin slices of Swiss cheese and cover the dish with foil if needed to prevent over-browning.
  • Let it rest before serving: Allow the casserole to sit for 5 minutes after baking. This helps the flavors blend and makes it easier to slice.

How To Store And Reheat Leftovers?

  • Refrigerate: First, let the leftover casserole cool to room temperature. Then, transfer it to an airtight container and store it in the fridge for up to 3 days.
  • Freeze: Allow the casserole to cool completely, then wrap it tightly or place it in a freezer-safe container. Freeze for up to 3 months. Thaw overnight in the fridge before reheating in the oven until warmed through.
  • Reheat: Preheat the oven to 350°F (175°C). Place the casserole in an oven-safe dish, cover with foil, and bake for 15-20 minutes until heated through.
