Reuben Cauliflower Casserole Recipe

Introduction

This Reuben Casserole brings all the flavors of the classic sandwich into a warm, comforting dish that’s perfect for any meal. Roasted cauliflower forms a tender base, layered with sauerkraut, tangy dressing, savory corned beef, and melted Swiss cheese for a hearty casserole everyone will enjoy.

Ingredients

• 1 head cauliflower, cut into bite-sized florets
• 3 tbsp avocado oil
• 1/2 tsp sea salt
• 1/4 tsp black pepper
• 1 (14-oz) can sauerkraut, drained
• 1 cup sugar-free thousand island dressing (or any kind you prefer)
• 1 lb corned beef, chopped into bite-size pieces
• 8 oz Swiss cheese slices (about 8 slices)

Instructions

1. Step 1: Preheat the oven to 400 degrees F (204 degrees C).
2. Step 2: In a large bowl, toss together the cauliflower, avocado oil, sea salt, and black pepper until evenly coated.
3. Step 3: Arrange the cauliflower in a single layer on a baking sheet and roast for 25-30 minutes, until tender and lightly browned.
4. Step 4: Keep the oven on. Transfer the roasted cauliflower to the bottom of a 9×13-inch baking dish. Layer the sauerkraut evenly over the cauliflower, then drizzle with thousand island dressing.
5. Step 5: Add the chopped corned beef over the dressing, then cover the top evenly with Swiss cheese slices.
6. Step 6: Place the casserole back in the oven for 10-15 minutes, until it’s heated through and the cheese has melted.

Tips & Variations

• For extra crispiness, broil the casserole for the last 2-3 minutes to brown the cheese on top.
• Substitute Greek yogurt mixed with ketchup and a bit of pickle juice for a homemade thousand island dressing.
• Try adding a layer of sautéed onions or pickles for additional flavor depth.
• Use leftover corned beef or substitute with pastrami if preferred.

Storage

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350 degrees F until warmed through, or microwave in short intervals to avoid sogginess. This casserole does not freeze well due to the texture of the sauerkraut and dressing.

Ingredients

Scale 1x2x3x

Vegetables

• 1 head Cauliflower (cut into bite-sized florets)

Oils and Seasonings

• 3 tbsp Avocado oil
• 1/2 tsp Sea salt
• 1/4 tsp Black pepper

Other Ingredients

• 1 14-oz can Sauerkraut (drained)
• 1 cup Sugar-free thousand island dressing (or any kind you want)
• 1 lb Corned beef (chopped into bite-size pieces)
• 8 oz Swiss cheese slices (8 slices; weight may vary depending on thickness)

Instructions

1. Preheat Oven: Preheat your oven to 400 degrees Fahrenheit (204 degrees Celsius) to prepare for roasting the cauliflower.
2. Toss Cauliflower: In a large bowl, combine the cauliflower florets with avocado oil, sea salt, and black pepper. Toss well to ensure the florets are evenly coated for roasting.
3. Roast Cauliflower: Spread the cauliflower in a single layer on a baking sheet. Roast it in the preheated oven for 25 to 30 minutes until the cauliflower is tender and lightly browned, which will bring out a nutty flavor and enhance texture.
4. Assemble Casserole: After roasting, keep the oven on. Transfer the roasted cauliflower evenly to the bottom of a 9×13-inch baking dish. Layer the drained sauerkraut over the cauliflower, then drizzle the sugar-free thousand island dressing on top. Add the chopped corned beef evenly, and finally cover the entire casserole with Swiss cheese slices.
5. Bake Casserole: Place the assembled casserole back in the oven and bake for an additional 10 to 15 minutes. This allows the flavors to meld, the casserole to heat through fully, and the cheese to melt and get bubbly, creating a golden topping.

Notes

• You can substitute avocado oil with olive oil if preferred.
• Drain the sauerkraut well to avoid excess moisture in the casserole.
• Use sugar-free thousand island dressing to reduce sugar content, but you can opt for regular dressing or homemade versions to suit your taste.
• If you like a crispier cheese topping, broil the casserole for 1-2 minutes at the end but watch carefully to prevent burning.
• This casserole is a low-carb alternative to the classic Reuben sandwich, ideal for keto-friendly meal plans.
