Why I love this Chicken Skillet Recipe

I love skillet dinners because they don’t require a lot of pots and pans to get dinner on the table. This meal comes together quickly and is full of lots of hearty vegetables.

We are slowing down with summer produce for sure and starting to fill our grocery cards with all the delicious Fall Produce popping up in stores.

But, there is still some zucchini always hanging around this time of year, and what better way to use it up than in this Italian Chicken, Mushroom, and Zucchini Easy Chicken Skillet Recipe!

This recipe is a heartier zucchini recipe thanks to the rich garlicky herb tomato sauce and a side of pasta, so it is perfect for those summer/fall transition meals when the weather hasn’t quite decided what season it wants to be.

This Italian Chicken, Mushroom, and Zucchini Skillet has definitely popped up on our meal plan recently when I was in need of something quick and easy to prepare.

Italian is often my go-to cuisine when I want something easy. There are so many things you can do with tomatoes, olive oil, and your favorite Italian herbs.

Ingredients to Make Italian Chicken, Mushroom, and Zucchini Skillet

Most of the ingredients in this recipe are easy to keep on hand in your freezer and your pantry, making it the perfect easy chicken skillet dinner for busy days! You’ll need:

  • chicken breasts or tenderloins
  • olive oil
  • butter
  • onion
  • garlic
  • mushrooms
  • zucchini
  • sundried tomatoes
  • fire roasted diced tomatoes
  • Italian seasoning
  • salt and pepper
  • balsamic vinegar

Optional if I have it on hand, I like to garnish with fresh chopped basil and parsley for an extra bit of green and flavor.

How to Make this Easy Chicken Skillet Recipe 

Start by patting the chicken dry – this helps it brown well – and season with salt and pepper according to your taste preferences.

You’ll then brown the chicken on either side in butter and olive oil in a large cast iron skillet. After the chicken is browned, set it aside and use the same pan for cooking the veggies!

Using the same skillet makes clean up so much easier, and the flavor of the vegetables will get an extra boost from all the browned bits and juices left behind in the pan from the chicken..

Then, saute the onion, followed by the mushrooms, then garlic and zucchini (adding each to the pan one at a time). After the veggies are cooked, add the tomatoes and seasonings. Stir in the vinegar. Then, taste and add more salt and pepper if desired.

Put the chicken (and any juices – again FLAVOR!) back in the pan. Spoon the sauce over, and bake covered at 350 degrees in the oven until the chicken is cooked through (165 degrees F on a meat thermometer) and the saute is bubbling.

What Vegetables Can I substitute in this Italian Chicken Skillet Recipe?

You can always swap out other vegetables depending on your preferences or just to use up what you have on hand. Don’t like mushrooms? No problem! Leave them out and pick something else

For substitutes I recommend the following as the best choices:

  • bell peppers – red, yellow, or orange,
  • yellow summer squash
  • patty pan squash
  • cubed eggplant
  • green beans

I don’t really recommend leaving out the diced or sundried tomatoes, however because they comprise the sauce in this recipe and it would be dry if they were eliminated. In a pinch, you can use jarred marinara sauce (or the best homemade marinara sauce if you have it in the freezer).

Roasted potatoes would pair well, too, if you prefer. Another potato recipe we love is Smashed Potatoes with Parmesan Gremolata.

A loaf of homemade or store-bought Italian bread is also a great side and is perfect for mopping up all the tasty sauce from the dish. For homemade bread, I love this Rustic Rosemary Garlic Bread.

For a side salad, I recommend Italian Mixed Greens Salad with Prosciutto and Lemon Dijion Vinaigrette or the Classic Copycat Olive Garden Salad Recipe to serve with this Italian Chicken Skillet Dinner.

Can I make this Recipe Gluten-Free?

Yes! There are many great gluten-free pastas on the market these days! 

I happen to really like Trader Joes Organic Brown Rice and Quinoa Pasta. Jovial Gluten-Free Pasta also gets really good reviews.

You can also always leave the pasta out and substitute another side from the list above. As mentioned, spaghetti squash is a great low carb, gluten-free substitute for pasta!
