Cheesy Chicken Veggie Sheet Pan Dinner
I can’t stop thinking about how juicy and tender the chicken comes out with that simple 20 minute milk marinate. Its so easy to add in to your prep because you start with the chicken, and while that’s marinating, you chop up your veggies and getting everything else ready.

We used chicken breasts, but you can also use boneless skinless thighs here too. Also customizable are the vegetables; eggplant, mushrooms, tomatoes, etc. can be subbed it. This is definitely a clean out your fridge type of meal.

Once you get the ingredients tossed all together and spread out on your baking sheet, make certain they don’t look dry to you, especially the vegetables! The beauty of this dish is that the breadcrumbs and pecorino coat the chicken and give it a nice texture. You can leave out the last step of mozzarella cheese if you’re not into that and this dish will still rock your socks off!

Delicious! My husband and 2 year old both asked for seconds!
Hi Whitney, I’m so glad you all loved the recipe!
Excellent! My family really enjoyed it! It was amazing how tender the chicken was from marinating it in the milk! I will use that great tip going forward in my other chicken dishes. Thank you for all your great recipes!!!
I’m a pitiful cook but for some reason your recipes make me look better at it!!!
So I made this and it was great. Not big on a lot of green peppers but I did add grape tomatoes and mushrooms and I used up what I had left of red peppers.
Awesome!!! Cheese it up!!! Even better!!!
Read your recipe every morning and have tried some. One gripe…. Too many frigging ads constantly having to “clean “ screens just to read.
This is so delicious and has so much flavor. I will definitely make this again.
So tasty and so quick to get in the oven! I did wonder if you were meant to drain the milk, I didn’t and it kept everything super moist, I had it several nights running!!
Do you drain the milk off? I didn’t, it’s so tasty and quick.
So good! I’m talking fire good! Even my brother, pickiest eater you’ve ever met!…ate it! I keep him on his toes by always trying new recipes every week. We’ve started a “Winner Winner Chicken Dinner” board on Pinterest of recipes to rotate. If he doesn’t like it, it doesn’t make it to the board. This one made And his rating, #1! Was also so easy to make!
Excellent, flavorful dish! My husband commented that he could definitely eat this once a week. I agree! The chicken was amazing!
Do you drain the chicken after marinating and before adding in with the veggies?
Love this recipe!! So super easy and delicious. Love that you can throw it all in together in a pan and it’s done! I’ve made a few of her things and they have all been delicious.
Hi Michele, that’s my favorite dinner too! I’m so glad you liked the recipe!
quickest dinner ever!! didn’t have any pecorino, marinaded the chicken, cut up my veggies added more italian (olives, marinated artichoke hearts and some capers), forgot the broccoli :(. cooked and then used shredded mozzarella for the finished. Perfect! thank you 👍
Amazing- this is a weekly meal !!
Absolutely delicious! I forgot the milk, so I didn’t marinate it. Also used fresh parm instead of pecorino, because that’s what I had. Used panko for the breadcrumbs. And didn’t do the mozzarella. I also forgot that at the store. Oops! It was still an amazing recipe that will be in our regular rotation.
This is my current favorite recipe! Came together in under 30 minutes.
I had frozen chicken breast tenders from TJs (thawed and marinated as directed), one yellow squash, an onion and a frozen bag of chopped broccoli. Fresh Parmesan instead of Pecorino.
I thawed and drained the broccoli and added it in the last 7 minutes. Everything else as written.
Very forgiving recipe and can’t wait to try other combinations.
The panko breadcrumbs aren’t necessary but they add a little something.
This dish is amazing. So easy, so versatile, and pretty healthy! Thanks so much for sharing! You are my go to on nights I have to cook!
