How to make oven baked chicken and veggies?
In a small bowl, mix garlic, parsley, olive oil, and dry spice blend including salt.
On a large baking sheet add onion and diced vegetables like carrot, bell peppers, and zucchini. Also, add chicken pieces. Then mix the chicken and vegetables with prepared garlic, oil and herb mixture to coat them evenly. Spread them on to the sheet in a single layer.
Bake veggies and chicken in the preheated oven until well done. Once the cooking is done, garnish with more fresh parsley and serve warm. Find instructions in detail below.

Helpful tips!
- Buying chicken - buy organic, hormone-free, pasture-raised chicken whenever possible. Here I used boneless and skinless chicken thighs. However, you can also use breast pieces if you prefer. Boneless chicken takes less time to cook compared to bone-in.
- Use a sharp knife for cutting the chicken. It will take less time and effort to cut the chicken into your desired size.
- Cut all the vegetables to roughly the same in size. These veggies will then cook evenly.
- Use a large baking sheet (I use 12 X 17" size) for this recipe. It will make your life easier to spread out the chicken and vegetables evenly in a single layer.

Ingredients
- 6 small chicken thighs boneless and skinless cut into bite-size pieces
- 3 medium carrot peeled
- 1 red and yellow pepper each
- 3 medium zucchini
- 1 large onion
- 2-3 tablespoon chopped fresh parsley
- 2 large garlic cloves finely chopped
- 1 teaspoon Italian seasonings mix
- ½ teaspoon red chili flakes
- 1 ½ tablespoon olive oil
- 1 tablespoon lime juice
- Salt and pepper
Instructions
- Preheat the oven to 400F.
- In a small mixing bowl combine parsley, garlic, Italian seasoning mix, chili flakes, oil, lime juice, salt, and pepper. Mix well and keep it aside.
- Cut carrots, peppers, zucchini, and onion into roughly 1” pieces. Spread them on a baking sheet pan. Also, add chicken pieces to the pan.
- Then add the garlic and herbs mixture. Using hand mix thoroughly to coat the chicken and vegetables.

- Finally, garnish with some fresh parsley and serve warm.
Notes
- Disclaimer: Vegetables in this recipe won't be crunchy--they will be tender. Vegetables will be perfectly ready in the first 20-25 min of cooking. However, in order to evaporate the water from the chicken completely, and get the roasted color and texture, it takes 30-35 min in total. That's the reason your veggies would get slightly overcooked. However, it doesn't affect the deliciousness of this dish.
- You can also use chicken breasts instead of chicken thighs. It may take less time to cook compared to thighs.
- You can skip the red chili flakes if you don't prefer it.
- We always purchase organic chicken. And about 6 small pieces of chicken thighs roughly weighs 1 ½ lb. You can keep a note of this when deciding how many chicken thighs you would use in this recipe.

Can someone recommend an oven temp? I’m so confused why there’s a full recipe without a temperature to cook it at!
Hi, I apologize for missing the key piece of info. The oven temp is 400F.
Ellie Dubelu says
The similar salmon dish says preheat oven to 400. But notes if you use chicken breast cook time a little less. These recipes seems fresh, inspiring, tasty...but most do not list oven temp. It is annoying to guess ad be wrong.
The oven temperature should be 400F. Sorry for missing this info.

What oven temp do you recommend? I have made this numerous times & LOVE the seasonings suggested & the overall dish. But I guess & use a different oven temp every time.
