A unique way to using up all those homegrown zucchini's is by making this yummy cheesy zucchini bake casserole.
Slice Ingredients:
Using a mandolin or this food processor slice zucchini and set aside. Next, slice onion as thin as possible and set aside. And lastly, mince garlic using this awesome garlic mincer (you can thank me later. LOL) and set aside.
Sauté Onions and Garlic
Place butter in a large skillet. Turn heat to medium and add onions. Cook and stir until onions soften. Then add minced garlic and continue cooking for about 1 more minute. Remove pan from heat. Add flour to mixture and stir to combine. Then stir in milk. Add Gruyere cheese and allow to rest.
Prepare Casserole Dish
Place half of the sliced zucchini into a 9×13 casserole dish. Pour half of the onion mixture on top and sprinkle with half of the parmesan cheese. Add the remainder of the sliced zucchini on top and cover with remainder of the onion mixture and parmesan cheese.
Bake
Place zucchini filled casserole dish in a 400 degree Fahrenheit preheated oven and bake for 30 minutes. Carefully remove from oven and allow to rest for 5 minutes. If the casserole dish has a watery look, gently tilt pan on one corner and spoon out any excess liquid. Serve warm and enjoy!
