Mediterranean Chicken with Portobello Mushrooms, Green Beans, and Mini Heirloom Tomatoes


Last week, I made a dish for dinner that we loved. I decided to make it again tonight and blog the recipe for you all. When I made this dish last week, I used only two portobellos, however, I did decide to use a lot more portobello mushrooms tonight. They are big, but they do cook down. I used two last week, and it just wasn’t enough. Today, I chose to use 7 portobellos, which was the perfect amount.

I started with thin sliced boneless, skinless chicken breasts that I seasoned and marinated in fresh squeezed lemon juice, minced garlic, kosher salt, pepper, red pepper flakes, Herbs de Provence and lemon zest. First, I zested two lemons and set the zest aside. Then, I squeezed the juice of those lemons over the chicken and spread four cloves of minced garlic over the top. In a small dish, I mixed together kosher salt, pepper, Herbs de Provence and red pepper flakes. I sprinkled that over the top of the chicken, covered the dish and placed it in the refrigerator for 2 hours to marinate.

I pulled the dish out of the fridge about 30 minutes before baking. I used the time that the chicken was coming to room temperature to prepare my portobellos and cut my green beans. When you are using a portobello mushroom, make sure to remove the gills on the underside. This is easy enough to do with a spoon.

I then cut the mushroom tops in strips and then in half. I placed them on half of a baking sheet, adding my beans to the other half. I then added the tomatoes to the top of the mix, sprinkled olive oil over the pan, sprinkled kosher salt and pepper over and mixed everything together with my hands.


Just look at the vibrant colors of the beans and mini heirloom tomatoes! This looks so healthy to me, which is just what I like … a meal that is healthy, but also satisfies.

I placed the chicken on a rack on a large baking sheet and then placed both sheet pans into a preheated 400 degree oven for 30 minutes.

I let the chicken sit on a cutting board for about 10 minutes to rest before cutting it.

I did cook quinoa to add just about a quarter cup to the bottom of the dish. On top of the quinoa, I placed a nice serving of the beans, mushrooms and tomatoes, topped with sliced chicken. For garnish and to finish the dish off, I added fresh basil and a sprinkle of feta cheese. Dennis told me that this is his new favorite chicken dish!

    Hi Kris – this looks great!
    Why do you remove the gills from the portobello? What happens if you don’t? I’ve never done that…

    1. Thank you, Jen! I read once that they can be woody and fibrous so it’s best to remove them. After I read that, I’ve always scraped them out. I was just looking at an article that says the gills can be used to flavor stock. That being said, I read that the gills will turn a sauce a brown, scuzzy, murky color – ick. 🙂 I think you’d love this dish, Jen!
