I’m recommending this Feta Cheese Frittata with Avocado for everyone who wants to make a special breakfast for Valentine’s Day! And this recipe is perfect for everyone who loves Feta cheese and avocado, but if you don’t have exactly the ingredients I used you can improvise the recipe with a different kind of cheese, or even different vegetables and still make a frittata that will be very tasty.

The recipe has some historical significance for me because I first posted it years ago just a few days before I retired from teaching elementary school and became a full time blogger! My photos from way back then were pretty sad, and when I decided to update the photos I made this a regular frittata that serves six! And we loved it when we tested the new-and-improved recipe; I hope you enjoy!

What is a Frittata?

A frittata is a type of Italian omelet that’s not turned or folded but is browned under the broiler to finish the cooking. It’s the type of dish you can happily enjoy for breakfast, lunch, or dinner, and the ingredient combinations are endless.

Can you make an avocado frittata without Feta cheese?

If you don’t have Feta or don’t want to use it, this recipe would be dreamy with Queso Fresca or Cotija, or one of the other crumbly Mexican cheeses. But if you don’t have any special cheese like that, it would still be delicious with simple grated Mozzarella or even the Three Cheese Mexican Blend that’s sold everywhere.

How low in carbs is this Feta Cheese Frittata with Avocado?

This tasty frittata with two of my favorite ingredients has only 3 net carbs and 12 grans of protein per serving.

What else could you use in a Feta Cheese Frittata?

If you’d like to make a frittata with Feta cheese but don’t have avocado (or aren’t a fan), I would love this recipe with Feta and bacon! Feta would also be delicious paired with red bell pepper, zucchini, or cherry tomatoes.

This easy Feta Cheese Frittata with Avocado is delicious for a quick breakfast, and if you're lucky you may have leftovers to eat another day.

Ingredients

• 1 T olive oil
• 6 green onions
• 8 eggs
• 2 T half and half (see notes)
• 1 tsp. Spike Seasoning (optional but recommended)
• fresh ground black pepper to taste
• 1 large avocado, diced into pieces about 1/2 inch across
• 3/4 cup crumbled Feta cheese (see notes)

Instructions

1. Slice 6 green onions, keeping the dark green part and the lighter and white parts separate.
2. Crumble desired amount of Feta and dice up one large avocado.
3. Beat eggs with a little half and half and some Spike Seasoning (affiliate link) or another all-purpose seasoning and pepper.
4. Saute white part of the green onions over medium heat in a bit of olive oil, using a 10 or 12 inch frying pan that has a lid.
5. Pour the beaten eggs over the green onion and immediately turn heat to low.
6. Start to preheat the broiler at this point.
7. When the eggs have started to barely look set around the edges (about 2-3 minutes) spoon the avocado pieces over the eggs, making sure they are well distributed in the pan.
8. Cook for 1-2 minutes, then crumble the feta over the top of the avocado and cook 2-3 minutes more.
9. Then cover pan and cook until the frittata is starting to brown on the bottom and barely set on top, about 8 minutes covered.

11. Sprinkle with green parts of the green onion.
12. Serve hot and enjoy!

Notes

Use milk, cream, or half and half in the eggs, whichever you prefer. If you don't have Spike Seasoning (affiliate link), use any all-purpose seasoning that's good with eggs. I love Feta Cheese, but use more or less Feta to taste.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Feta Cheese Frittata with Avocado is a great breakfast for low-carb and Keto diets. Avocados are considered a “good fat” for the original South Beach Diet, but are limited to 1/3 avocado per day and you’d probably have to use less cheese to make this South Beach Diet approved.
