Traditionally, Chicken Marsala is made with a thin chicken cutlet cooked in Marsala wine and mushrooms but we amped up our Chicken Marsala by stuffing it with cheesy caramelized onions and then add some sun dried tomatoes and spinach to the finishing touch.

This recipe was one the the first dishes I cooked for Terry on our date night. He didn’t believe me that chicken breast could be moist and flavourful and I was about to prove him wrong. I always love a good challenge in the kitchen, don’t you?

The great thing about this recipe is I wanted to make it an interactive date, so I had to make it simple (but flavourful!). Terry had never cooked a single thing in his life, unless you count boiling water and burning toast cooking 😉 so I thought it would be a fun thing to do together to show him the kitchen isn’t such a intimidating scary place. I urge you to do the same, especially for a date night. It a fun activity that cuts the tension and nervousness a bit because you both are focused on the tasks in the kitchen and conversations and laughs will be had. Guaranteed.

The end result? A flavourful ‘fancy looking’ dish to enjoy and lots of laughs and memories.

Did I complete the challenge? BOOYAH! you bet I did! This is one of the rare dishes he still remembers to this day the most. 🙂



All ingredients can be found at your local grocery store.

You can substitute the cheeses with your cheese of choice. However, to get the gooey cheesiness, you should put a bit of mozzarella in it.


You can keep this recipe traditional as well and omit the sun dried tomatoes and spinach. However, I found the sun dried tomatoes gave it a nice umami kick and the spinach? It gives it a nice colour and some extra silky texture to the sauce.



There are two ways to flatten the chicken. You can:

  1. The Easy Way – Place the chicken between two pieces of saran wrap and go at it with a mallet, frying pan or rolling pin. I personally don’t prefer this method because I find it takes a lot longer because the chicken slides around inside the saran wrap when I’m trying to hit it since it’s has a dome shape thickness to it.
  2. The Quick Way – Butterfly the chicken first, then give it a few whacks with a mallet, frying pan or rolling pin. This is my preferred method as it’s quick!


What is ‘butterflying’?

Butterflying is essentially, cutting something across (but not all the way through) and opening it up like a book to give you a bigger and thinner surface area to work with. Think of it as opening up a book, the 2 sides of the pages gives you a bigger surface area once it’s opened up. In this case, the wings of a butterfly is why it’s called butterflying.


First step, safety first. Put your hand on the chicken and make sure your hand is above the line where you will be cutting across sideways. Putting your hands this way prevents you from nicking or cutting off your fingers 🙂 Unless you’re into that kinda thing.

Once you have your hand in the right place, look at the middle point on the side of the chicken. Place your knife there and slowly cut side ways while peeling back the chicken so you can see what you’re doing. Do not cut all the way through, you want a small piece of meat still intact at the end. Cut about 80% across. As a guideline to keeping my cuts somewhat straight, I use my cutting board and keep my knife parallel to it.

When you are about 80% through, open it up! It’s kinda looks like pages of a book or ‘butterfly’ wings. You see why we didn’t cut all the way through? we wanted 1 solid piece. *High five!* You just butterflied a chicken! If you cut too high or too low and made holes, no biggy it happens! A few more times doing this and you’ll get the hang of it.

Next, put the chicken between 2 pieces of saran wrap and whack it! You can use a bowl, a mallet, or my personal fave – a frying pan. Get out your frustration! Careful not to go too nuts, you want to somewhat keep the flattening even and not too thin.

Tip #1: Don’t skip the saran wrap step. When you are trying to flatten out chicken, the saran helps in 2 ways. It makes it easier to flatten because the meat has a more slippery surface to spread and it makes it easier to peel off to use. Bonus? Keeps chicken bits from flying everywhere as well. A good shield!

Once the meat has been somewhat flattened, add your cheese and caramelized onions. (You will need to caramelize the onions ahead of time)

To keep the chicken stuffing from falling out during our flipping step in the frying pan we can use toothpicks to hold them it in place. Just don’t forget to take them out, they aren’t fun to eat. 🙂


Tip #2: Refrain from using minty toothpicks. 🙂 Don’t ask me how I know this. haha


Then we will dredge the chicken in flour. We don’t want to go overboard here, the key is  putting flour on it and then tapping the excess flour off. Why? We are using the flour as an aid for browning the chicken. Too much flour and it will just burn and fall off the chicken.

Then we fry it up in the frying pan with oil, butter on medium high heat for 4 minutes a side. The goal here is to get some browning on the chicken. It’ll look something like the image below. When you get to that point on both sides, take it off the pan and set it aside.

This part is quick:

  • Add some more oil or butter to a medium heat pan, add the mushrooms and cook it until it is brown and the water has evaporated
  • Add Marsala wine in and cook it for a few seconds to remove the alcohol
  • Add in the sun dried tomatoes, garlic and chicken stock and add the chicken back in and cook it for another 5-10 minutes to get the sauce all mixed in with the chicken.
  • Lastly, this step is optional but add in the corn starch mix to thicken up the sauce. I personally prefer a thick sauce but if you prefer it runnier then omit this step.
  • Don’t forget to remove the toothpicks before serving! 🙂

  1. That is one fine looking plate. I really like the addition of sundried tomatoes and the spinach strewn overtop. A really striking plate. And refraining from using minty toothpicks. Those are words to live by!

    1. Yes, I only have mint toothpicks in the house. I don’t even know where they came from! I don’t use toothpicks. I personally love sundried tomatoes, they are like bursts of flavour with every bite! I decided to experiment with it and voila, the Frankenstein of Chicken Marsala! lol 🙂

    1. I love caramelized onions in everything too haha! You can probably even stuff these with…anything really! I love keeping dishes simple as long as it doesn’t sacrifice flavour. One of the goals of the blog is to keep a database of recipes for myself that were successful so that one day, Terry (who doesn’t cook) could start making me meals from my blog. Yes, I realize this might just be a dream. haha

  2. Yum! Your chicken marsala looks divine, and I love the step-by-step instructions and photos. There are way too many recipes out there that don’t do chicken breast any favors, this is one that proves you can have juicy, delicious chicken breast for dinner, thank you!

    1. I’m so glad you liked the step by step instructions! When I first learned how to stuff a chicken, the internet was not around and it seemed like such an intimidating task! I’m so glad we can now easily learn new things! Yes, chicken breast this recipe floored Terry and proved him wrong about dry chicken breast, it was fun to see and even more fun to make.

    1. Trust me, I am the same way as you haha. Dark meat is my fave, especially bone in, but I had to prove Terry wrong haha if done right, chicken breast can also be good as well! But dark meat all the way in my books.

  3. A lot my fav date nights with Scott involves us cooking or baking in the kitchen. It is a lot of fun, but we tend to make double the mess somehow! Mint toothpicks adds the hint of mint flavour! ha ha! Just kidding! Lovely dish as always! I really like the addition of sun dried tomatoes and cheese! 🙂

    1. Haha that sounds so cute! Double the mess is okay! As long as you’re not on clean up duty 😛 …it really does add a hint of mint o_O Thanks Marie!

    1. Thanks so much Alyssa! I am so happy that you find the step by steps useful. 🙂 chicken with tomatoes and cheese – not good eats. haha! 🙂
