How to Make Easy Oven-Baked Chicken Breasts with Roasted Vegetables Recipe
Step 1: Prep Your Oven and Chicken
Start by heating your oven to 400°F (200°C). Meanwhile, trim any excess fat from your chicken breasts and pat them dry with paper towels—this step helps the marinade stick better and ensures a nice crust forms during baking.
Step 2: Make a Simple, Flavorful Marinade
In a mixing bowl, whisk together the olive oil, garlic powder, onion powder, salt, and black pepper. This straightforward marinade infuses the chicken with layers of flavor while keeping it incredibly juicy.
Step 3: Let the Chicken Soak up the Goodness
Coat your chicken breasts thoroughly with the marinade. Let them sit for 10-15 minutes — this little resting period means the flavors get time to mingle and soak deep, which really makes a difference on the palate.
Step 4: Prepare Your Roasted Vegetables
Chop your mixed vegetables into bite-sized pieces. This keeps them cooking evenly alongside the chicken and makes every forkful a delightful combination of textures and tastes.
Step 5: Layer It All in Your Casserole Pan
Spread the chopped vegetables evenly in the bottom of your casserole pan, then nestle the marinated chicken breasts right on top. This method ensures the veggies roast in the chicken juices, soaking up extra flavor as everything cooks together.
Step 6: Add Fresh Herbs and Bake
If you’re using herbs, sprinkle them over the chicken and vegetables for a fresh hint of garden goodness. Cover the pan with foil and bake for 25-30 minutes. The foil keeps the chicken moist and helps the vegetables soften beautifully.
Step 7: Check and Finish Cooking
After baking, use a meat thermometer to check the chicken’s internal temperature; it should reach at least 165°F (75°C) for safe eating. If it’s a bit shy, pop the pan back into the oven uncovered for another 5-10 minutes to brown and finish cooking.
Step 8: Rest Before Serving
Let your casserole rest for 5-10 minutes after coming out of the oven—this resting time locks in the juices, making the chicken tender and flavorful when sliced.
Step 9: Serve and Enjoy
Slice the chicken breasts and serve them alongside those perfectly roasted vegetables. The combination is unbeatable, a comforting and colorful plate you’ll love coming back to again and again.
How to Serve Easy Oven-Baked Chicken Breasts with Roasted Vegetables Recipe

Garnishes
A sprinkle of freshly chopped parsley or thyme right before serving can add a pop of color and a bright, herbal note that enhances the flavors beautifully. You can even add a light drizzle of extra virgin olive oil or a squeeze of lemon for a refreshing finish.
Side Dishes
This Easy Oven-Baked Chicken Breasts with Roasted Vegetables Recipe stands well on its own but pairs wonderfully with a simple side like creamy mashed potatoes, fluffy rice, or even a crisp green salad. These sides offer complementary textures and round out the meal perfectly.
Creative Ways to Present
For a bit of flair, try serving the sliced chicken on a bed of the roasted vegetables in shallow bowls, drizzled with a light balsamic glaze or your favorite sauce. It’s an easy way to make this comforting dish feel even more special, whether for a family dinner or casual entertaining.
Make Ahead and Storage
Storing Leftovers
Leftover chicken and vegetables can be stored in an airtight container in the refrigerator for up to 3 days. Keep the sauce or pan juices together to help retain moisture and flavor when reheating.
Freezing
You can freeze portions of this dish for up to 2 months. Make sure to cool it completely before transferring to freezer-safe containers or bags. Thaw overnight in the fridge for best results before reheating.
Reheating
Reheat leftovers gently in the oven or microwave until warmed through. To avoid drying out the chicken, cover with foil or a microwave-safe lid, and consider adding a splash of water or broth to keep the veggies moist.
FAQs
Can I use bone-in chicken breasts for this recipe?
While bone-in chicken can work, it will require longer cooking time to ensure the meat is fully cooked and tender. The recipe is optimized for boneless, skinless breasts for even cooking and convenience.
What vegetables work best with this Easy Oven-Baked Chicken Breasts with Roasted Vegetables Recipe?
Bell peppers, zucchini, and carrots are fantastic choices because they roast evenly and complement the chicken’s flavors. You can also experiment with broccoli, cherry tomatoes, or green beans based on your preference and seasonality.
Do I need to marinate the chicken beforehand?
Marinating for 10-15 minutes is recommended to infuse flavor, but if you’re pressed for time, you can generously season the chicken right before baking. The dish will still be tasty, though a short marinade enhances the depth of taste.
Can I make this recipe gluten-free?
Absolutely! All the ingredients used are naturally gluten-free, but double-check spice blends and any packaged items to ensure they don’t contain gluten additives.
How do I know when the chicken is perfectly cooked?
The most reliable method is using a meat thermometer to check for an internal temperature of at least 165°F (75°C). This ensures that the chicken is safe to eat and remains juicy and tender.
