Instant Pot Recipes

I got an Instant Pot and I admit I am addicted to it. I think next to my slow cooker, Instant Pot recipes are now my new favorites to whip up in the kitchen. Why? Because it is a fix and forget it.

Easy Recipes

One reason I might be in love with my Instant Pot is that I have a need for easy recipes. Since I got back from my much-needed vacation, I realized I need to simplify my life. A frittata recipe made in the slow cooker is exactly what I need for easy recipes.

Feta Cheese Frittata

I am a lover of feta cheese. So I was very inspired to make a feta cheese frittata after I finally got to make an omelet with lemon and feta for the Persian man I adore so much.


When we had this feta egg dish, and I do have to say he loved it, I knew I had to do some type of brunch recipe that features feta. A frittata came to mind.

I wanted more than just feta cheese in my Instant Pot frittata. What else could I add to make this a yummy frittata? How about my other favorite, mushrooms.


I have never made a frittata. I made quiches, but never a frittata. So I had to do a bit of research to find a mushroom frittata.

In my research, I found this mushroom and spinach frittata recipe from the New York Times. It sounded perfect. I knew  I could modify that spinach frittata recipe and make an Instant Pot recipe with feta.
