The last two weeks of our CSA boxed delivery and we get for the first time celeriac or better known as celery root. I have always seen them in the grocery store but never knew what to do with it so I never bothered to try them until now. It was suggested to try to make scalloped potatoes with added celeriac, so I gave it a shot. I initially used this recipe, as a base since I never made scalloped potatoes from scratch, but made some adjustments which is marked with an asterisk (*). Still needs work as you will see in my notes below, but it is a great start and will try again.
Ingredients:
3 tbs butter
1/4 cup flour
1/4 tsp dried minced garlic*
1/8 tsp dried thyme*
2 cups chicken broth or vegetarian equivalent
1 1/2 cups grated extra sharp cheddar cheese
1 lb boiling potatoes*
1 lb celeriac root peeled*
1/2 cup Italian seasoned bread crumbs*
Salt and Pepper to taste
Directions:
Preheat oven to 350 degrees F
In a heavy saucepan, melt butter over moderately low heat and whisk in flour to make a roux for about 2 – 3 minutes. Whisk in broth and bring to a boil. Whisk in garlic and thyme and simmer for about 2 more minutes, then whisk again until thickened. Remove from heat and whisk in cheese and any salt and pepper you wish to add, until cheese is fully melted.
Peel potatoes (optional) and celeriac (a must) and slice to about 1/8 inch thick. In a 2-quart shallow baking dish, butter or spray cooking oil and make a layer of potatoes and sauce, celeriac and sauce, and repeat until you have between 4 – 5 layers. Sprinkle bread crumbs on top and bake uncovered in the oven for 1 hour or until potatoes are tender.
Overall Impressions
Not sure if it was my oven, but 1 hour does not cut it, more like an hour and thirty minutes. The celeriac took longer to soften. Will try raising the temp to 375 and see if that helps. Also even with the extra sharp cheddar and added spices I found it somewhat bland. Will go for fresh minced garlic next time and add more thyme and a stronger cheese like parmesean or a vecchio asiago d’Allevo.
One thing I found with peeling celeriac is that like apples, it browns quickly. So I would recommend preparing at the last possible moment. But the flavor should not diminish.
