How To Make Rutabaga Gratin

For gratin dishes, potatoes are more commonly used but for this unique recipe, we substituted with rutabaga for a different kind of flavor.

Preparation: 20 minutes
Cooking: 50 minutes
Total: 1 hour 10 minutes

  1. Preheat oven to 375 degrees F.

  2. Peel and cube rutabaga. Place in a pot of cold water and bring to a boil. Simmer 10 to 15 minutes or just until tender. Do not overcook, they will cook more in the oven. Drain well.

  3. Meanwhile, cook onion in butter on medium-low heat until translucent, about 5 minutes. Add flour and thyme, cook 2 to 3 minutes.

  4. Add milk a little bit at a time stirring until smooth after each addition. It will seem thick at first but will smooth out with each addition.

  5. Cook over medium heat until thick and bubbly. Remove from heat and stir in cheeses until melted. Season with salt & pepper to taste.

  6. Toss sauce with rutabaga and transfer to a 2-quart baking dish. Bake uncovered for 35 to 40 minutes or until lightly browned.
