You either like or love it or not. There doesn’t seem to be an in between.

Cooking liver and onions is really simple with this recipe. Of course, I love to fry my liver, too, but this recipe is a lot less ‘messy’ and for sure, easier clean up. 

Liver with Onions

I grew up loving liver. Yes, crispy chicken livers as well as liver, onions and gravy. And, if you haven’t tried my crispy chicken livers, well then what in Sam Hill are you waiting for!! 


When I was younger, Mom prepared healthy nutritious and thrifty meals, and liver was one of those ‘inexpensive’ meats that filled the bill.

Little did I know as a kid that liver is a superfood and it can be really exquisitely chic as Tuscan Liver Pate which I learned to make in cooking school in Florence Italy! 

Liver and Onions with Gravy

My version of liver is without the gravy, and it’s more on the ‘healthier’ side of preparation.

But, there are times when I walk back into those wonderful childhood memories with the liver, onions and gravy.

Here’s to peace and knowing that there are other liver lovers out there!
