I realized that there were three zuchinni hiding in the bottom of my fridge as I was putting away groceries last night.
Here's what I did with them:
Preheat oven to 450
Slice the zuchinni into 1/4-inch slices
Chop two large cloves garlic
Chop a shallot
1 T butter and 1 T olive oil in a heated pan
Cook until the zuchinni are crisp-tender (four or five minutes)
I added a generous 1/4 c half-and-half (or cream or milk or whatever you have on hand) and let it heat through. Then added about 1/4 c parmesan and gave it a good stir to coat everything. Stir in 1/3 c panko bread crumb. Put the mixture into a small casserole dish.
Cover with an additional 1/3 c panko and 1/3 c parmesan. Bake until the top is toasty brown on top. About 10 minutes (I think I left mine closer to 15, but I like the crunch).
