Chicken Cordon Bleu Baked Frittata

2  cups cubed, cooked chicken
4 oz fresh spinach
1/4 cup chopped onion
3 cloves garlic, minced
1/3 cup finely shredded Gruyère
1/4 cup milk
10 eggs
3 oz thin sliced lean serrano ham, cut into 1/4-inch wide strips
freshly ground black pepper
olive oil


Preheat oven to 350.

Saute the onion and garlic until the onion is soft. Add the spinach and chicken and cook until the spinach is wilted.

In a medium bowl, beat together the eggs, milk, cheese salt, and pepper until fluffy*. Fold in the , vegetables/chicken mixture and ham.

Oil an 8×8-inch baking dish. Pour the mixture into the dish and bake for 40 minutes or until fully set in the middle. Allow to cool 5 minutes. Slice into 9 squares and serve.

*I love my egg beater for this task.

My thoughts:
I am so happy I discovered baked frittatas a few years back. I had been making frittatas the old fashioned way by starting them on the stove top but this way so much easier! It is sort of like strata but there no layers. Anyway, they are super easy and when you make them in an 8×8 inch baking dish they are the perfect size for dinner with leftovers (they reheat remarkably well in the microwave or oven)–so many baked egg dishes assume you are serving a huge crowd! 
For this baked frittata, I used some leftover cooked chicken (even better it, it was leftover Costco rotisserie chicken I had froze so bonus points for using up leftovers), some Gruyère and serrano ham (thanks Aldi for carrying this stuff on the regular and cheap*!) for a sort of riff on chicken cordon bleu but without the frying and some spinach tossed in so I got some veggies in. Super easy, super satisfy and best of all, super tasty. The cheese and serrano ham add a ton of flavor that really makes the dish. Serve it with a light vegetable dish or just with some crusty bread.

  1. So it would be ok if I made this on Christmas eve and refrigerated it, then reheated it on Christmas morning for brunch? What if I wanted to reheat it in the oven instead of microwave, is that possible?

  2. That should be fine. I always reheat it in the oven, Matt uses the microwave because he is at work and doesn’t have other options.

    You could just mix it together (and just put it in a ziplock if your baking dish doesn’t have a lid) and bake it the next day if you want. It takes about 20 minutes to reheat and 40 fully cook so if you have the oven space, that’s an option.

  3. That is if you don't mind bringing a bag of raw eggs with you! 🙂

  4. That's a great idea, I'll bring that baggie full of eggs! ☺

  5. Just make sure to either take the cooked chicken/onion/garlic/spinach separately or cool them completely before mixing into the raw egg the night before.

  6. I absolutely love this idea. Pinning.
