Ingredients

3 Zucchini (cleaned and sliced thin)
Salt
1 Onion (small)(minced)
2 Cloves Garlic (minced)
2 Tbsp Butter
1 Tbsp Flour
½ Tsp Thyme
½ Cup Heavy Cream
4 oz Cream Cheese
½ Cup Parmesan Cheese

Instructions

Clean, slice, and salt your zucchini. Arrange on a paper towel and let the zucchini sweat out the excess moisture for 30 minutes. Blot with a paper towel to absorb the water.
Preheat the oven to 400 degrees F.
Once the moisture is removed arrange the zucchini in a greased 9x13 baking dish.
Prepare the sauce: In a small saucepan saute the minced onion, garlic, and thyme in butter.
Add one tablespoon of flour to create a roux and slowly add the heavy cream and cream cheese. Whisk to combine.
Add 1/2 the cheddar cheese to the sauce.
Pour the sauce over the zucchini and toss to combine.
Place in the oven for 20 minutes. Once the zucchini is tender add the second half of the cheddar cheese and return to the oven for an additional 10-15 minutes until the Zucchini Au Gratin is golden brown on top.
Serve immediately with your favorite protein. Enjoy!
