What is a Zucchini Frittata?

The stand out reason why this recipe is a frittata and not a quiche is that it has no crust. Frittatas simply get made with no pastry or crust underneath.

There is a lot of similar recipes that people get confused by. Quiches and frittatas are are almost identical, omelettes are aligned closely as well.

Another option when making frittata is to have an ingredient with texture on top for a bit of variety. You might remember we did that in our Tater Tot Breakfast Frittata. That recipe is here if you want to check it out!

This Best Ever Zucchini Frittata is going to be your next all time favourite recipe. Frittatas are so easy to make and taste delicious. Oven baking them is a great way to cook them and the house will smell amazing as the eggs are bubbling away.

This vegetarian zucchini frittata recipe uses only 8 ingredients. You might already have most of them in your fridge and pantry already. It is a no fuss recipe to make when you don’t have a lot of time and want to get dinner in the oven in a hurry.

Our easy zucchini frittata recipe is similar to our Gluten Free Zucchini Slice with the main difference being that the zucchini is sliced for our frittata and not shredded.

How do you make Zucchini Frittata

Making a zucchini frittata is easy!

The trick is using thin slices of zucchini.

I recommend using either your food processor or mandolin instead of a knife, as not only is it faster, is is also the easiest way of slicing zucchini thinly.

Most food processors have a ‘slice’ blade on them, often it is as simple as turning the blade from one side to the other to find it.

How to make easy Zucchini Frittata

Keeping the ingredients and method for this recipe as simple steps will allow us to make an incredibly easy zucchini frittata.

The thing about it being easy, doesn’t mean it has to be boring though.

This recipe has 2 types of cheese and lots of flavour from the dried onion and garlic powder. The seasoning from the salt and pepper adds a nice little touch as well.

Step by step method to make Zucchini Frittata

The method to prepare our zucchini and egg mix for this recipe are very straightforward.

You might remember that when we did our Zucchini Parmesan Muffins we ensured we packed maximum flavour into the zucchini.

The reason why that is so important is because zucchini (also known as courgette) often has a reputation for being bland or watery.

We need to get some flavour into our zucchini as we are preparing it and it will fly off the table so quickly you will question whether you actually served it in the 1st place!

For our Zucchini Parmesan Muffins, we sliced and seasoned the zucchini in the same way we need to for this recipe.

In fact, we follow the exact same process to start with. Those steps are shown in the photo below:

The easy method to make zucchini frittata is:

  1. Preheat your oven (it will take a lot less time to cook if you do this) 
  2. Line a slice tray with baking paper
  3. Slice your zucchini
  4. Season zucchini with dried onion, garlic power, salt, pepper and parmesan
  5. Crack your eggs
  6. Use a fork to lightly whisk
  7. Stir to combine your eggs and cream
  8. Add cheese to the mix
  9. Continue to stir to combine
  10. Transfer your zucchini parmesan mix into the slice tray 
  11. Pour in egg mix
  12. Top with a little reserved seasoned zucchini parmesan
  13. Bake in oven

The perfect way to serve this frittata is with mustard yoghurt. Simply combine greek yoghurt and djion mustard for a sauce with zing!

Vegetarian Zucchini Frittata is all about the eggs!

Free range eggs are the best as they are fresh and so good to cook with.

We use 6 eggs, as we need the egg mix to allow our frittata to have a nice height to it for thick slices.

You can use a hand helder (immersion) beater to do these steps which will make for a very smooth egg mix. The steps are shown in the photos below.

Zucchini Frittata egg mix method

To cook our zucchini frittata one option is to use a cast iron skillet. That is a popular choice as most skillets are round and you will end up with an easy frittata you can cut into wedges.

I like to use my slice tray for this recipe as I find I enjoy changing it up every now and again so whilst the recipe tastes the same, the shape and size of your portions can be different.

If you use a skillet, spray it with oil and if you use a slice tray, line it with baking paper. This will prevent the eggs from sticking.

FAQs to cook your Zucchini Frittata

  1. Choose small or medium zucchini as opposed to large ones (less water)
  2. When adding the seasoning to the zucchini stir well to mix it through
  3. The frittata will take between 40 – 45 mins to cook
  4. Parmesan is a key ingredient for flavouring the dish
  5. This frittata freezes and reheats very well
  6. Once it is cooked, leave it to cool for a couple of minutes to make slicing easierZucchini Frittata steps 12 to 18 with text overlay

  • Food processor


Zucchini Frittata

  • 2 zucchini Note 1
  • 6 eggs
  • 1/4 cup parmesan cheese
  • 1 tssp dried onion Note 2
  • 1 tsp garlic powder
  • 1/2 cup cream
  • 1/3 cup cheese
  • 1 tsp salt
  • 1 tsp pepper

Mustard Yoghurt

  • 1/3 cup greek yoghurt
  • 2 tsp djion mustard
  • 1/2 tsp cracked pepper


Zucchini Frittata Method

  • Preheat oven to 200°c/400°F, gas 6
  • Cut of the top and bottom of your zucchini then use food processor to slice thinly Note 1
  • Season the sliced zucchini with dried onion, salt, pepper, garlic powder and parmesan cheese Note 2
  • Crack eggs into mixing jug, lightly whisk them, pour in your cream, stir together, add cheese and stir to mix together well
  • Line your slice tray with baking paper
  • Transfer the zucchini mix into your baking tray and reserve a little of it for the top of the frittata. Note 5
  • Pour egg mix into the tray to cover the seasoned zucchini, move tray back and forth slightly with both hands to even out egg mix.
  • Top egg mix with reserved zucchini and parmesan
  • Oven bake for 40 mins. Ensure no wobble in centre. If frittata is wobbly, cook for another 5-10 mins until fully set.
  • Allow to cool slightly before slicing
  • Serve in slices with mustard yoghurt.

Mustard Yoghurt

  • Combine yoghurt and mustard in a small bowl and stir to combine
  • Top with a little cracked pepper



  • Note 1 go for small to medium zucchini as these have less water content than large. Plus large ones won't fit in the shoot of the food processor. 
  • Note 2 these will be in the herbs and spices aisle at the supermarket, in packets. I love using these as they are SO easy to cook with.
  • Note 3 it doesn't really matter which order you season the zucchini, what is more important is that the seasoning and parmesan is really mixed well into the zucchini so it is thoroughly seasoned. 
  • Note 4 just the tip and base of it. Use either a food processor or mandolin to make really thin slices 
  • Note 5 it is easier to cut the slice when it is cooler as it is firmer. Otherwise it tends to slide everywhere if still hot. Allow to cool slightly and serve hot. 
  • Note 6 When you do this, layer the zucchini the way I have done in the photos.

I like that you specify to use thin slices. For some reason I love zucchini when it’s sliced thin, but not when it’s too thick. I think it’s the texture. It’s absolutely delicious with the eggs and cheese!

Adrianne September 13, 2019 - 7:26 pm

Cheers Alyssa for the feedback. Yes, I think thick is better for dishes where it be be cooked thoroughly before serving. Thanks – you!
