BAKING DISH OF ZUCCHINI AU GRATIN

INGREDIENTS TO MAKE IT

HOW DO YOU MAKE IT?

Clean, slice, and salt your zucchini. Place the zucchini slices in a colander, sprinkle generously with salt (3/4 teaspoon salt is a good amount), and drain over the sink for 45 minutes. (Doing this prevents a watery casserole!) Pat dry with a paper towel. Preheat the oven to 400 degrees F. Once the moisture is removed arrange the zucchini in a greased 9×13 baking dish.

CLEANED AND ARRANGED ZUCCHINI

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.

PRO COOKING TIPS:

  • If you allowed the zucchini to rest and your dish was still too watery. Next time saute or grill the zucchini this will add flavor and remove the moisture.
  • You can add Italian Seasoning (about 1 teaspoon) if you want more flavor.
  • You can use any cheese you want. It’s up to you. I used a blend of white cheddar and parmesan.
  • Shredded zucchini can change things up.
  • Add a crunchy topping, use panko bread crumbs if you want, or crushed pork rinds for a low-carb alternative.

HOW TO REHEAT AND STORE LEFTOVERS?

Cover leftovers in an airtight container and store them in the refrigerator for up to 3 days. To reheat use the microwave or 350-degree F oven until warm.

CAN YOU FREEZE ZUCCHINI AU GRATIN?

I would avoid freezing this zucchini au gratin recipe, the zucchini will be mushy and the dairy will begin to separate. I don’t think it would look appetizing once defrosted.
