Ingredient Notes
Made with sautéed marinated artichoke hearts, onion and garlic with eggs, cream and loads of cheese. This is a perfect low carb keto breakfast.
- Artichoke Hearts: a jar marinated artichokes, strained and patted dry to remove moisture.
- Onion and Garlic: I like to sauté the onions and garlic with the artichokes to get them nice and soft for the frittata.
- Eggs: would this even be a frittata without eggs, that being said I am sure there are some vegan frittata recipes.
- Cheddar: a marble cheddar was used but you can use any melty cheese you prefer.
- Parmesan: used to coat the bottom of the casserole dish and also used to top the frittata to give it that sweet yet salty nutty flavour.
- Cream: giving a creamy texture to this frittata
- Nutmeg: adding that warm, nutty and slightly sweet taste with citrusy undertones.
Steps by step instructions
How to make Keto Artichoke and Onion Frittata?
STEP 1: In a skillet over medium heat sauté the onions and garlic with 1 tablespoon of olive oil. Drain the can of marinated artichokes and then pat dry with paper towel. Add to the frying pan and continue to sauté until soft, then set aside.
Preheat the oven to 350°F
Generously grease a 9"x13" casserole dish with butter and then evenly sprinkle a ¼ cup of grated parmesan over the butter. (save the remaining parmesan for topping the frittata later). Transfer the artichoke mixture to the casserole and spread out evenly.
STEP 2: In a large bowl whisk together the eggs, cream, shredded cheddar, oregano and nutmeg. I grated the cheddar on the diagonal to create short shreds, this makes it easier to whisk together.
Whisk for about 1 minute until the egg mixture is a frothy on top.
Gently pour egg mixture over the artichoke mixture in the casserole dish, spread out evenly if needed.
STEP 3: Bake at 350°F for 30 minutes, remove from oven and sprinkle the top with the remaining parmesan and place back in the oven for another 6 minutes. The frittata should be slightly golden on top.
Remove from oven and allow to slightly cool before cutting into squares. Gently remove each slice and enjoy. Top with chopped parsley and freshly cracked black pepper (optional).
Recipe tips
Top Tip: strain the marinated artichokes and pat dry, otherwise there will be too much moisture and make the frittata watery.
Tip: shred the cheddar on the diagonal and continue to maneuver and angle the cheddar so it makes short shreds. This make it easier to whisk in with the egg mixture.
- Serving: serve with a side green leafy salad or these cauliflower bites
- Storage: store covered in plastic wrap in the fridge for up to 4 days. Frittata can be eaten cold or allow to come to room temperature. Warm up in the microwave or oven.
Recipe variations
Variations of this keto breakfast frittata are endless, here are just a few of my favourite ways to have them.

- Pizza - Top the meat lovers frittata with low carb tomato sauce, pepperoni and fresh basil for a pizza frittata
