When zucchini flowers are in season, you need to stuff them! This is the perfect low-carb dish for summer.

These Italian-style zucchini flowers (aka courgette flowers) are deliciously crisp on the outside with a soft cheese filling. They are stuffed with creamy ricotta and goat's cheese flavored with fresh lemon zest and a generous handful of fresh mint.

Traditional fried zucchini flowers are either coated in flour or in a tempura-style batter and then they are deep-fried. To make my keto-approved batter I used whey protein powder combined with egg whites, water, salt and pepper, similar to this Low-Carb Fish and Chips recipe and then deep-fried them in avocado oil.

Recipe Tips

A little warning before you proceed. These can get a bit fiddly and it's easy to accidentally tear the flowers when you're stuffing them but they are totally worth the effort!

I used zucchini flowers as well as baby zucchini with flowers attached to them. Depending on the size of the flowers you will need to stuff them with different amounts of cheese filling. If you happen to have any leftover filling, you can use it as stuffing in halved and hollowed out zucchini and bake them in the oven.

I kept this keto recipe vegetarian by using cheese, herbs and eggs but you can use other fillings such as gluten-free sausage meat or Mexican chorizo.

The egg yolks will make the cheese filling a bit runny so it's good to refrigerate the stuffed zucchini flowers before frying. You could add some grated parmesan cheese or any hard cheese as that will thicken the filling and add amazing flavor.

Depending on the consistency of the batter, you'll get different thickness of the coating. If you prefer thinner coating, use a little more water to thin it down. I started with 1/4 cup (60 ml) of water and the batter was a bit too thick so I ended up using about 1/2 cup (120 ml) water which resulted in thinner, crispier coating.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

I have been trying to grow zucchini in my garden. I never knew that the flowers were edible! That's something new for me to try 😊
I tend to react to whey protein isolate in drinks (ie liquid sources) since I am lactose intolerant. I tend to do better with harder cheeses in moderate amounts. Would I have a better chance with the powdered whey protein isolate, or do just have bit the bullet and test it out. I've never bought it because of the price of a clean, soy free source.

First time I tried stuffed zucchini flowers was in Greece and have been making them ever since 😊 You can also just stuff and bake them (no coating needed). You could stuff them with some Mexican chorizo or some sausage meat and herbs and skip the coating or try using egg white protein powder. I have not tried using egg white protein powder though so I'm not 100% sure it will work.
