Low Carb Parmesan Radish Gratin

I dislike raw radishes, but LOVE roasted and cooked radishes! In the keto world, radishes and turnips make great substitutes for potatoes in soups and other recipes. The first time I saw a casserole recipe similar to this, it was created for potatoes and contained several high carb ingredients, such as flour and whole milk. I thought it would be worth a try to make a few ingredient substitutions and make it low carb—the result was wonderful! You can make this delicious side dish with red or daikon radishes (or maybe even turnips) and I think you’ll be quite pleased too.

Low Carb Parmesan Radish Gratin

Makes twelve 1/2 cup servings

8 oz. Parmesan cheese

2 slices cooked bacon, crumbled

1 green onion, thinly sliced

1 tablespoon snipped fresh chives

1/2 tablespoon fresh chopped thyme (or use 1 teaspoon dried)

1/2 tablespoon fresh chopped rosemary (or use 1 teaspoon dried)

2 tablespoons unsalted butter, cut into small cubes

6 cups thinly sliced radishes (about 2 lbs, leaves removed)

Salt and pepper

6 tablespoons coconut or almond milk

6 tablespoons heavy cream

1/2 teaspoon xanthan gum

Snipped fresh rosemary and thyme for garnish (optional)

1. Preheat the oven to 325 degrees F and grease a 1.5 quart casserole dish; set aside. Using a wide vegetable peeler, shave the Parmesan cheese (about 2 cups) or use pre-shaved Parmesan; set aside.

2. In a small bowl, combine the crumbled bacon, green onion and chives. Stir to combine. In the prepared baking dish, arrange 1/2 of the radishes to cover the bottom of the dish. Sprinkle with 1/2 teaspoon salt and pepper, half of the bacon mixture and half of the herbs. Top with 1/2 of the Parmesan and dot with half of the butter cubes. Repeat layers.

3. In a medium bowl, whisk together the coconut or almond milk, heavy cream and xanthan gum until the xanthan gum is incorporated and dissolved (you can use a stick blender to make this easier). Pour the cream mixture evenly over the radishes.

4. Bake, covered for 1.5 hours. (If using foil to cover, spray the underside with non-stick cooking spray.) Increase oven temperature to 400 degrees F. Bake, uncovered for 15-20 minutes more or until the radishes are tender and the top is golden brown.
