A dear patient of mine gifted me a HUGE zucchini this year and I thought I would try something new. This recipe for Grain Free Zucchini Walnut Brownies (GAPS, Paleo) brings the words, healthy treat to a whole new level!

Grain Free Zucchini Walnut Brownies

I’ve seen brownies made with zucchini and I never thought much of it. However, working with grain free flours always requires something that imparts moisture. Zucchini is certainly good for that, so I gave it a try and you would never guess there was a vegetable in these deeply satisfying treats!

Zucchini has a lot of water in it but it also has some good nutrients.

The zucchini or courgette is a summer squash and is a hybrid of the cucumber. Along with certain other squashes, it belongs to the species Cucurbita pepo. Zucchini can be dark or light green. A relative, the golden zucchini, is a deep yellow or orange color.

Zucchini is known as a vegetable, which means it is usually cooked and presented as a savory side dish. However, the zucchini is actually an immature fruit, being the swollen ovary of the zucchini flower.

Nutrition in Zucchini

Zucchini is a good source of  Vitamin A, thiamin, niacin, phosphorus and copper, and a very good source of dietary fiber, Vitamin C, Vitamin K, riboflavin, Vitamin B6, folate, magnesium, potassium and manganese.

The omega 3 to 6 ratio is almost 2 to 1, which is excellent.

Walnuts are also high in omega 3 fats.

Whether you consider zucchini to be a fruit or a vegetable, these zucchini brownies are healthy and grain free!
