30 Minute Chicken Frittata with Spinach and Feta
This delicious and healthy recipe for chicken frittata with spinach and feta is a one-dish dinner that is ready in just 30 minutes, making it the perfect weeknight solution. Savor the combination of succulent chicken, tender spinach, creamy feta, and juicy tomatoes all baked into a fluffy, golden frittata.

I’ve written about my love for frittatas, how simple ingredients (often bits that you need to use up) bound together with eggs can become such a terrific, good-for-you, and just plain good meal.
We regularly rotate sausage and swiss chard (or spinach or kale), potato and caramelized onion, and salmon and vegetable (with a yummy creamy feta sauce!) frittatas through our menus and now this delicious chicken and spinach version.
It not only has cooked chicken and spinach (or chard, or kale..greens are interchangeable here!), but also can hold other seasonal vegetables you may have, in addition to feta cheese and a topping of fresh tomatoes.

Ingredients & Substitutions
These are the ingredients I used this time – see the variations below for ideas on how you can change up the basic recipe!
- Cooked chicken – this can come from either a slow cooked spiced whole chicken or a store bought rotisserie chicken.
- Spinach – you can use either fresh or frozen and both chard and kale make good substitutions.
- Feta – I prefer block feta as it seems moister and lasts longer in storage than crumbled feta. Any cheese can be substituted.
- Eggs – large eggs are used in this recipe.
- Onion – regular or sweet can be used, as well as shallots or sliced green onions.
- Garlic – I love the flavor this brings, but it’s not required.
- Tomatoes – it’s lovely to serve this with a sprinkling of chopped or halved small tomatoes, but it’s optional as well.
- Other ingredients – olive oil, salt, pepper, milk or water, and basil (or herb of choice).
- Optional seasonal vegetable – I used a small amount of fresh asparagus I had, but this is a great way to use up any small amount of vegetable you have.

How to Make Chicken Frittata with Spinach
In a 10-inch cast iron skillet (or oven-safe skillet) over medium heat cook onion, garlic, and any added vegetables 5-8 minutes. Add cooked chicken and spinach and set aside to wilt while mixing the eggs.
Mix together the eggs, water and seasonings and add 1/4 cup of the cheese.
Pour the eggs evenly over the top of contents of skillet. Do not stir. Cover and let the eggs set around the edges and somewhat in the middle.
TIP: Using a thin spatula, lift the edges and tip the pan so the liquid egg from the middle runs to the edge and under the cooked egg. Continue all the way around the edge until most of the egg is cooked (or use the spatula to break through the center a bit in places to allow the uncooked egg to flow through).
When most of the eggs are firm, with just some uncooked egg on top, put the pan under the broiler (TIP: cover the handle with foil if it is not metal) and let it broil 3-5 minutes or until all the egg is cooked and the top is browned.
Sprinkle the remaining cheese over the top along with optional garnishes, if using, and serve.

Variations
Like any frittata, the ingredients can be added to, changed up, and seasoned to become a totally different dish – which is why I’m such a fan of this dish. Here’s a list of variations to get you started:
- Chicken and kale with pepper jack cheese and addictive tomato chutney as a topping.
- Cooked pork and kale or spinach with gorgonzola and roasted garlic topping, served with spicy rhubarb chutney.
- Ground turkey or beef and spinach with sharp cheddar and sweet and spicy onion marmalade or caramelized onions.
- Shredded beef and kale with goat cheese and tomatoes.

Storage
Keep in airtight containers in the refrigerator for up to a week.
TIP: This is a great meal prep recipe – store the individual servings in separate containers for grab-and-go breakfasts and lunches all week.
I did mention how yummy this chicken frittata was, didn’t I? As in, scrape-the-lovely-cast-iron-skillet-clean good?
Side Note: Can I just say again that every time I cook eggs in my cast iron pan and they come out cleanly, I am amazed all over again? SO glad I kept trying and came to love cast iron!
So, have I convinced you that you need to add this (and other frittatas!) to your menu rotation yet, like the reader below?

Thanks for a great idea! We just this week started picking the first of our spinach and mustard greens, chard is farther behind. Yum – this will be one more dish to try and know that it will be cleaned up! I am sure that my husband will be saying we need more greens next year!
yum, this DOES sound good….and I’m stuffed from eating supper! Is that glutony??? LOL
I have a recipe for artichoke, bacon, and gruyere quiche that is to die for…
Ooo, that does sound wonderful, Sharon! (and I’m full, too, ha!).
I’ve been meaning to try my hand at cooking frittatas…now you’ve convinced me to go for it. This recipe looks delicious.
I hope you go for it, Sharon – they really are a great quick dinner to have in your repertoire!
