Raise your hand if you can get down with a crazy delicious sheet pan chicken dinner that is easy to make and BURSTING with flavor! 🙋🏼
I know it’s cliche to talk about how busy we are, but seriously you guys, life has been more than a little busy lately. Like so busy I’m not even sure how I manage to remember to brush my teeth and put deodorant on in the morning 😂
Between traveling abroad for a big work trip, taking care of family stuff, blogging, and generally just trying to keep it all together I have (sadly) not had a lot of extra time to cook.
So we’ve been keeping our weeknight dinners pretty simple – lots of big salads paired with clean proteins and… SHEET PAN DINNERS. Um I’m not sure where the heck I’ve been on this but I’m 100% jumping on this band wagon and I can now say that I FULLY UNDERSTAND the hype.
I mean… One pan to clean? Less than an hour to make? Hands off delicious dinners that have the perfect protein to veggie ratio?
COUNT ME IN.
This healthy mediterranean sheet pan chicken and vegetable dinner has been pretty regular in the rotation and nobody’s mad about it. I mentioned it in my last “What I Ate this Week” post and we’re still loving on it. It’s super flavorful, easy to make, has interesting flavors // colors, and makes excellent leftovers. AKA it’s checking all the boxes and looking super fly at the same time 😉
Ingredients
This sheet pan chicken dinner is made up of four main components:
- Chicken: I use boneless + skinless chicken thighs, but you could use whatever type of chicken you like. Just keep in mind that cooking times will vary with different cuts and whether your chicken is boneless or with the bone.
- Vegetables: potatoes, onion, and broccolini are the veggie stars of this dish.
- Spice mix: for that yummy flavor!
- Garnishes: pickled red onions, olives, herbs, and feta cheese. The feta cheese is optional and the dish is just as delicious without it if you’re dairy free. The garnishes really add a nice brightness to the finished dish.
The spice mix is a really basic blend of dried spices that most likely you already have on hand that adds a ton of depth and flavor to the dish.
It is made with:
- Cumin
- Onion powder
- Garlic powder
- Paprika
- Chili flakes
- Salt + pepper
How to make this healthy mediterranean sheet pan chicken and vegetable dinner
- Start by mixing the spice mix together. Then toss the chicken, potatoes, and onions together with all of the spice mix and some avocado oil.
- Arrange potatoes and onions in a single layer on a lined baking sheet and top with chicken thighs. Move to the oven and set a timer for 30 minutes.
- While chicken and potatoes cook prepare the garnishes and broccolini.
- Quick pickle the red onions in a red wine vinegar, water, and salt mixture. Note on the pickled red onions: Often quick pickled red onions are made with some type of sugar also, but I left out the sugar so that this recipe can be Whole30 compliant and paleo! You won’t miss the sugar at all. Leaving it out actually gives them a little extra zippy-ness that I LOVE!
- In a separate bowl toss trimmed broccolini with avocado oil and salt and set aside.
- After 30 minutes check chicken and potatoes. The chicken should be cooked all the way through and the potatoes should be tender and starting to brown. If they need more time leave them in the oven to continue to cook, checking every 5 minutes or so until done.
- Once chicken is all the way cooked and potatoes are tender and crispy, remove the sheet pan from the oven and tuck the seasoned broccolini into empty spaces on the tray. Be careful not to overlap the individual pieces of broccolini too much so they cook evenly.
- Turn the oven onto high broil, and cook the broccolini until it is bright green and just starting to char.
- Serve topped with all the yummy garnishes – chopped parsley, pickled red onions, olives, and crumbled feta cheese if using!
Is this sheet pan chicken and vegetable dinner healthy?
Yes! This mediterranean sheet pan chicken dinner is made with clean and wholesome ingredients that you will feel good about serving yourself and your family.
It is 100% gluten free, paleo friendly, and Whole30 compliant (if you leave out the feta cheese).
Dietary modifications
This healthy mediterranean sheet pan chicken and vegetable dinner is 100% gluten free.
To make it:
Paleo and Whole30 compliant: Leave out the feta cheese as a garnish
Vegetarian and vegan: Swap the chicken for a plant based protein like tofu. If using a plant based protein: It likely will not need as long in the oven as the chicken. To modify the recipe for this swap, roast the baby potatoes and onions on their own until nearly finished cooking. Add the tofu and cook until starting to crisp up and brown, and then proceed with the rest of the recipe as written!
Other swaps + modifications: The chicken can be swapped for any other type of protein that you want to use. Skirt steak, pork chops, pork tenderloin, sausage, shrimp, scallops, or fish, would all be delicious choices. Just adjust the cooking time as needed depending on the protein you choose.
Notes on the recipe
- This sheet pan chicken recipe is made with chicken thighs, roasted baby potatoes, caramelized onions, and broccolini, but you can easily substitute other vegetables and proteins.
- The best baking pan sheet for this recipe is a three quarter size tray measuring 15 x 21.
- You can use any type of olives you like, but my favorite are the buttery and rich castelvetrano olives. If you’ve never tried them before you MUST. Even non olive loving peeps can get behind these mild and buttery olives. You can buy them jarred, but most olive bars usually stock them as well.
- If you want to try a dairy free feta cheese for this recipe I recommend this plant based option!
