Zucchini Gratin Trial: Gluten-free, Nut-free

July 26, 2013

I’ve been looking for ways to use zucchini other than in zucchini bread. So when I saw a few recipes for zucchini gratin, I decided to give it a try. I settled on the one from Our Best Bites to use as my base, since it didn’t call for any eggs.

The Changes

I used crushed GF Rice Krispies to make gluten-free crumbs. I also cooked with olive oil and coconut milk to limit the dairy. But I used real swiss cheese. Since Joseph can handle some baked milk and some cheese powder, I wanted to see how he did with baked cheese.

GF rice krispies, coconut milk, salt, pepper, garlic powder, olive oil, corn starch, nutmeg, onion, zucchini, swiss cheese

The Method

Cook the onion in oil until tender. Add zucchini, cover, and cook for 10 minutes. Add spices, then cook uncovered for about 5 more minutes. Realize that my pictures look nothing like Sara’s, and then that I completely missed reading that the recipe was supposed to be cooked over LOW heat.

Pour into an 8 x 8 pan. In a small bowl, crush GF Rice Krispies into crumbs, then add cheese. Sprinkle over zucchini, then bake at 400 degrees F for 20 minutes.

What I Thought

This side dish wasn’t that appetizing to look at. Hence why neither of my kids touched it. And while there was a slight bitter taste due to overcooking the ovens, overall the taste was good. My husband agreed, saying he would rather have something that looks awful and tastes good than looks good and tastes awful. So, I’d give this a shot again later.
