Potato and Yam Gratin

Recently I found myself with a “hodge-podge” of ingredients in the kitchen…and I was feeling adventurous, so I created a new side dish that was actually quite tasty!

 

Here are the ingredients I used…

 

1 large white potato, peeled and sliced

2 medium sweet potatoes peeled and sliced

1 medium onion, peeled and sliced

1/4 cup heavy cream

2 T. butter

2 T. flour

1/2 cup vegetable broth (made from one Knorr Vegetable Bouillon cube)

fresh thyme

fresh flat-leaf parsley

salt and pepper

1/2 C. Parmesan cheese-divided

2 T. bread crumbs

1 T. Extra Virgin Olive oil

 

Spray oven proof dish with cooking spray

Place a layer of sweet potatoes in the dish

Add a layer of sliced onion

Add salt and pepper

Add layer of white potatoes

Sprinkle layers with fresh herbs (use any kinds you like…or dried may be substituted)

Dot with butter

Repeat layers until finished

Combine bouillon cube and water in coffee cup and microwave until liquid is hot.  Stir to combine.  Stir in flour and whisk well.  

Add cream to the cup and stir.

Pour over potato layers.

 

In separate bowl combine 1/4 C. Parmesan cheese, bread crumbs and olive oil.  Sprinkle mixture over casserole.  Then sprinkle the remaining grated Parmesan cheese over all and add more herbs if desired.

 

Preheat oven to 400 degrees.  Bake, covered, for 45 minutes.  Uncover and continue baking at least 15 minutes more or until potatoes are tender.  Remove from oven and let stand for about 15 minutes to firm up before serving.
