Zucchini frittata – a healthy low carb keto frittata recipe

My husband is following a ketogenic diet and always looking for healthy keto breakfast recipes, low carb lunch ideas, and keto-friendly dinners. Eggs and zucchini contain a lot of protein and fibre and are very filling. Simon can wolf down vast amounts of food, and this low carb zucchini frittata kept him fed and satisfied for quite a while.

Another thing I love about this keto zucchini frittata, aside from it being delicious low carb, healthy and gluten-free, is that this is such a flexible meal idea that you serve at any time of day. Even with cutting the veggies, it only takes about 40 minutes to put a warm paleo zucchini frittata on the table.

What ingredients do I need to make zucchini frittata from scratch?

Here is the ingredients list you need to make this healthy vegetarian zucchini frittata:

Vegetables

Zucchini is one of my all-time favourite veggies, and there are so many ways to make low carb recipes with zucchini. If you’re looking for more low carb and keto-friendly dinner recipes, check out these ketogenic meatballs with zucchini noodles.

I also incorporated a bell pepper and a small onion into this healthy frittata recipe to round out the zucchini flavour.

Eggs

Eggs are a rich source of protein and an excellent paleo breakfast option to give you long-lasting energy for the day. I like to use fresh organic free-range eggs, free from GMOs.

Non-dairy milk

Next, we need dairy-free milk. Because my husband is gluten intolerant, I use gluten-free oatmilk. You can, of course, use other vegan milk alternatives such as coconut milk, soy milk, or rice milk.

Herbs

Traditional Italian herbs give this vegetable frittata recipe a delicious Mediterranean aroma. I used fresh oregano and thyme, but dried herbs work fine too, for example, this ready-made Italian seasoning.

Garlic

Adding garlic is optional, and it’s okay to skip. 1 finely minced garlic clove or 1/2 teaspoon garlic powder is enough to season this gluten-free keto zucchini frittata.

Sea salt and pepper

A bit of salt and black pepper add to the savoury flavour. I used finely ground sea salt, of course, kosher salt or table salt are excellent as well.

You also need a splash of olive oil for frying. This is a dairy-free frittata recipe, so I didn’t use any cheese. If you want you can add 1/2 a cup of shredded mozzarella, cheddar or grated parmesan to the egg-and-milk mixture.

How to make the best zucchini frittata

Are you ready to make healthy cast iron skillet vegetable frittata? The items below are helpful to make a delicious cast iron skillet frittata:

Cast iron skillet

A cast iron skillet is great for cooking my healthy baked frittata recipe. Because a cast iron skillet is ovenproof, you can use the skillet on the stovetop to sauté the vegetables and then simply place it in the oven to finish the frittata.

Jug and whisk

I like to whisk the eggs and non-dairy milk in a jug or bowl with a spout because it makes it easy to pour the mixture over the vegetables without creating a mess.

Mandolin slicer

Zucchini frittata is one of the easiest low carb zucchini recipes ever. To cook the frittata perfectly, cut the zucchini into thin slices. A mandolin slicer makes the process quick and easy.

Tips to make delicious keto zucchini frittata in the cast iron skillet

And here are 4 tips to make the best keto vegetarian frittata:

Precook the zucchini and pepper

Make sure the vegetables are cooked and seasoned before you add the eggs. Zucchini that are still raw won’t be fully cooked by the time the eggs are done.

Use a mix of healthy veggies

And your by no means limited to zucchini and bell peppers to make a healthy low carb keto frittata. Broccoli, carrots, potatoes, spinach, mushrooms are all vegetables, which you can use to cook a delicious vegetarian cast iron skillet frittata. Check out this baked pumpkin frittata if you’re looking for more healthy frittata recipes.

I found that 8 eggs to 2 1/2 – 3 cups vegetables is a good ratio to make a delicious frittata. Just make sure to cut the veggies into bite-sized pieces. And it’s best to precook potatoes as they often won’t fully cook.

Don’t overbake the zucchini frittata

Watch the frittata while it bakes in the oven, so it doesn’t dry out or burn. My family likes their frittata well cooked – no wobbly, undercooked centre. I also found that picky eaters usually prefer eggs to be well done. I prefer a 10 minute baking time, but the frittata is usually ready after 8 minutes. The centre of the frittata should be set and opaque.

Can you freeze frittata?

Yes! If you want to freeze this easy paleo zucchini frittata, simply slide the frittata from the pan onto a cutting board and cut it into wedges once it has cooled down. Then simply store the frittata in airtight containers in the freezer for up to two months.

Can you reheat frittata?

When you’re ready to eat, reheat the zucchini frittata in the microwave or a preheated oven until hot. If you have leftover frittata, I recommend using these glass meal prep containers. You can store, freeze, and then reheat leftovers all in the same container. Super practical!
