Simple Keto Vegetarian Breakfast Recipe
Frittatas are one of my favorite keto breakfast recipes – eggs, veggies and cheese wrapped up in one dish. They are quick meal ideas that easily double for brunch or lunch. I really enjoy the cold leftovers.
Easy keto recipes make breakfast meal prep a breeze. With just five minutes of prep, you can put food in the oven and then move on with your day.
I used to struggle with frittatas because they were delicious but too eggy and light. It seemed like I could eat the whole thing and still be hungry.
Here’s the secret: You must treat them like keto omelettes – stuff them full of your favorite fillings!
There are many variations to try, so feel free to be creative with whatever you already have on hand. Like a Low-Carb Baked Omelette, baking a frittata is an excellent opportunity to use leftover veggies and herbs.
How to Make a Keto Frittata Recipe
Gather ten total ingredients and you’re halfway to making a spinach and feta frittata in just twenty minutes. That includes 5 minutes of prep time and 15 minutes for baking!
Ingredients
Eggs – Opt for free-range, pastured eggs or raise them yourself!
Heavy whipping cream – In addition to healthy fats, cream gives the omelette volume and an incredible texture.
Garlic, green onion, thyme – Fresh flavors to delight your taste buds.
Salt and pepper – Just a pinch of seasoning here!
Butter – Choose grass-fed butter, if you can
Spinach – Wilt it a little in the skillet before combining with the eggs. Substitute with any of your favorite leafy greens: Swiss chard, kale, sorrel, etc.
Feta cheese – If you don’t have feta, another soft crumbly cheese will substitute. Goat cheese or queso blanco are suitable alternatives.
Directions
First, begin by preheating the oven to 350°F (177°C).
Second, whisk the eggs, cream, and green onion together in a large bowl. Season with thyme, salt, and pepper.
Third, add butter to an oven-proof skillet over medium heat on the stovetop. Once it melts, sauté minced garlic for 1 minute, then add the spinach and stir until it begins to wilt.
Next, remove the spinach from heat and combine it with the eggs in a bowl.
Then, crumble the feta cheese with your hands and stir until combined.
If needed, add more butter to your pan, so nothing sticks. Pour the egg mixture into the skillet. Use a fork or spatula and move the spinach around until it’s distributed evenly throughout the frittata.
Finally, bake for 15-20 minutes until the top turns golden brown and the edges set.

What size pan is best for this 4-serving recipe? I’ve got a 9″ and a 12″ cast iron skillet and I don’t want it to bake too thin and end up an egg pizza. 😀
Great question Terri! I would go with the 9-inch skillet and will make a note in the recipe so it is more clear for others too. Thanks for asking!
