Mediterranean roasted vegetables are one of those recipes that look like you put in way more effort than you actually did. Zucchini, cherry tomatoes, yellow pepper, and red onion roast in the oven with olive oil, Italian seasoning, and a little salt and pepper until they're tender, caramelized, and full of flavor. Everything comes together on one pan in about 30 minutes, which makes this one of my most-used weeknight side dishes.
I'm a big fan of simple, flavorful roasted veggies. Roasting enhances their natural sweetness, and they pair beautifully with pan-seared pork loin steaks for an easy protein-forward dinner, or served alongside pasta al forno when you're leaning into comfort food. Leftovers are a bonus; reheat them with Yukon Gold mashed potatoes for an easy weeknight side combo.
The beauty of this recipe is its versatility-it works year-round! In the summer, I love roasting zucchini, onions, and tomatoes, while in winter, I swap in hearty veggies like squash, carrots, and Brussels sprouts. Customize the flavor with your go-to seasonings or herbs to suit your taste. The method stays the same just roast, season, and enjoy!

Ingredients and Substitutions
- Vegetables. I used a combination of cherry tomatoes, zucchini, yellow bell pepper, and red onion. The sweet flavors in the bell pepper and cherry tomatoes balance the earthy zucchini and the stronger flavors in the onion. You can also mix in other veggies like beets, broccoli, cabbage, carrots, sweet potatoes, eggplant, mushrooms or Brussels sprouts.
- Garlic. Roasting garlic is optional, but highly recommended! Simply add a head of garlic to the tray and allow it to roast with the rest of the vegetables. Once cool enough to handle or at room temperature, squeeze the garlic out of the bulb and add it to the vegetables.
- Italian seasoning. A simple pre-mixed blend works great. If you don't have any, use a mix of dried basil, oregano, and thyme, or swap in fresh herbs if you prefer.

How to Roast Vegetables
Step 1
Preheat the oven. Drizzle the chopped vegetables with olive oil, sea salt, pepper, and Italian Seasoning, and toss to combine. Transfer to a prepared baking sheet and spread them across the pan in a single layer. Add the garlic, if using.
Step 2
Roast for 20-25 minutes, or until the vegetables are softened.
Sarah's Top Tips for Roasted Vegetables
- Cut the vegetables to a similar size. This is going to help them cook through evenly.
- Cut the top off the garlic bulb to allow the olive oil to drizzle down inside the garlic bulb. This will help caramelize the garlic cloves and increase the flavor.
- Don't skip the high heat. Roasting at 425°F is what gives you that caramelized, slightly golden finish on the edges. Lower temperatures tend to make vegetables soft and lose their color. High heat is what makes these taste so good.
- Don't crowd the pan. I personally love roasting on my Pampered Chef Stone Bar Pan because the stoneware pulls moisture away for a better crisp. If you don't have a stone, Nordic Ware sheet pans work beautifully, too.
- Add the garlic. The optional garlic head, roasted alongside the vegetables, is one of my favorite tricks for adding more flavor to the whole pan without any extra work. The cloves get completely soft and sweet, and you can squeeze them out and mix them right into the vegetables before serving.
Why Your Roasted Vegetables Aren't Charring
This usually comes down to two things: an overcrowded pan or not enough heat. Make sure you're using a large pan with the vegetables spread in a single layer, and don't go below 400°F. Excess moisture on the vegetables can also cause steaming. Pat them dry if they seem very wet before tossing with olive oil.
Serving Suggestions
These roasted vegetables make an easy side for chicken dinners. Try them with grilled Mediterranean chicke for a classic pairing, or serve alongside air fryer lemon pepper chicken thighs for a zesty, quick dinner option. When you're craving something extra cozy, they're great next to honey garlic chicken thighs for a sweet-savory contrast.
These veggies are also a natural fit alongside my one-pan balsamic caprese chicken - the tomatoes in both recipes complement each other perfectly.
Storage & Reheating
Fridge: Store leftover roasted vegetables in an airtight container in the refrigerator for up to 4 days.
Reheat: Reheat in a 375°F oven for about 10 minutes until warmed through, or warm them in a skillet over medium heat with a small drizzle of olive oil. You can also microwave them in 30-second intervals, though the oven or stovetop keeps the texture better.
Make ahead: Chop the vegetables and toss them with olive oil and seasoning up to 1 day ahead. Keep them covered in the fridge until you're ready to roast. This is a great way to cut down on dinner prep on busy weeknights since the hard part is already done.

Absolutely delicious Sarah, it will be made often
Ana says
I made it for 35 people and I was told several times those veggies were delicious! I have to agree. Delicious, healthy and very easy to make with a large baking pan. I used foil on my pans so, no mess either (I was baking other things at the same time, I had to simplify. I felt like I was playing Tetris in my oven.) Just make sure nothing is crowded on the pan so it won't steam the veggies, particularly the zucchini. I found the bottom oven tray was the best position for that charred look and flavor, just watch it closely. It will definitely be a regular in my house! Thank you!!

Thanks very much!
Wendy says
This is an easy vegetable dish to prepare. I double the recipe so I have these veggies every day. Sometime I put them in scrambled eggs or just on the side of any meal I am preparing. Have made this receipe 5 times.
Sarah Hill says
Ooh I love that you put these in eggs, that sounds so good! So happy to hear you love the recipe.
Gloria says
We're going to try roasting with convection the next time because the dish was sort of watery. However, tasted great!
Sarah Hill says
Hi Gloria, glad you enjoyed it! Let me know how it goes with the convection oven. Sometimes the tomatoes and/or zucchini can get a little watery from the salt so maybe thats what happened here.

Delicious and easy to execute!
