What to do with zucchini?

It's that time of the year again, when you ask yourself, "What am I going to do with all this zucchini?"

Whether you grow it yourself, or have lovely neighbors, friends, or family that share their bounty with you, you'll need great zucchini recipes to use it in. 

When it comes to zucchini, I like both sweet zucchini recipes like this popular recipe for Chocolate Chip Zucchini Muffins  and savory zucchini recipes like this Amish recipe for Zucchini Casserole

Zucchini squash is a mild flavored vegetable that pairs nicely with tomatoes in Italian flavored dishes. It can even stand in for pasta in dishes like Greek Zucchini Ribbon Salad and makes a great side dish, snack or appetizer like these Zucchini Carrot Fritters.

Because it's such a versatile vegetable, zucchini is one of my favorite ingredients to work with.

Zucchini Appetizer Recipe 

This recipe for Zucchini Appetizer is an old one. I've been making this recipe for over 20 years now and it's still one of my very favorite ways to enjoy garden fresh zucchini.

This zucchini appetizer consists of zucchini, sweet onion, seasonings, eggs, cheese, oil, and Bisquick Pancake and Baking Mix and is baked until golden brown. The combination of Bisquck and eggs, makes the squares sort of quiche like with a very delicate flavor.

I have to confess, I've never been a huge fan of Bisquick. I've made this recipe both with Bisquick and without Bisquick, and I have to say, I like the Bisquick version better. That's not to say that you can't make this recipe without Bisquick, because you can. I've provided a substitute in the NOTES section of the recipe card. I'm just saying I like how it comes out better with the Bisquick. Not sure why.

I also switch back and forth (depending on what I have on hand) between using dried oregano and dried marjoram in this recipe. Marjoram is a milder cousin to oregano, with similar flavor profiles. If you aren't a fan of oregano, give marjoram a try.

These zucchini bites bake up nice and light. They make a lovely first course paired with your favorite glass of wine. They also make a wonderful healthy snack, that's light on calories. I've even been known to eat one or two squares for a quick, grab and go breakfast!
