- 4 ounces cremini (baby bella) mushrooms (sliced, about 1½ cups): Provides a meaty texture; feel free to switch to portobello or button mushrooms.
- 1¼ cups yellow squash (sliced about ½” thick): Contributes a mild taste, making it versatile; zucchini works well too.
- 1¼ cups zucchini (sliced about ½” thick): Adds moisture and tenderness; if unavailable, use other summer squashes.
- 1 cup green pepper (cut into 1″ pieces): Imparts a fresh, slightly bitter flavor; red or yellow bell peppers can be used for sweetness.
- 1 cup red pepper (cut into 1″ pieces): Brightens the dish with its vibrant color and adds light sweetness; you can even mix colors.

How to Make Roasted Vegetables | Easy Oven-Baked Side Dish
- Preheat the Oven: Begin by preheating your oven to 375°F. This step is crucial for ensuring that your vegetables roast evenly.
- Prepare the Sheet Pans: Line 2 sheet pans with parchment paper. This makes cleanup a breeze and prevents the veggies from sticking.
- Toss the Vegetables: In a large bowl, toss all the chopped vegetables—carrots, asparagus, mushrooms, yellow squash, zucchini, green pepper, red pepper, and yellow pepper—with 3½ tablespoons of extra virgin olive oil, 1½ teaspoons kosher salt, and ¼ teaspoon black pepper. Ensure every veggie piece is beautifully coated.
- Arrange on Pans: Spread the seasoned vegetables onto the lined sheet pans in a single layer. Avoid overcrowding; this helps them roast rather than steam.
- Initial Roasting: Place the pans in the preheated oven and roast for about 15 minutes. You’ll start to smell those delicious aromas wafting through your kitchen.
- Stir and Add Tomatoes: Take them out after 15 minutes. Give the veggies a good stir, then add 1 cup of whole grape tomatoes, re-spreading everything evenly across the pan.
- Finish Roasting: Return the pans to the oven, rotating them for even cooking. Roast for another 15 minutes or until the vegetables are tender and lightly caramelized, adjusting time to your preferred doneness.
- Garnish and Serve: Once ready, serve immediately and, if desired, sprinkle with minced fresh parsley for a pop of color and freshness.
Storing & Reheating
To store any leftover roasted vegetables, place them in an airtight container and refrigerate for up to 5 days. If you prefer freezing, you can store them in a freezer-safe container or bag for up to 3 months. To reheat, simply pop them back in a preheated 375°F oven for about 10 minutes, or until warmed through, keeping in mind that the vegetables may lose some crispiness during reheating. A quick spritz of olive oil can help refresh their flavor.
Chef’s Helpful Tips
- Make sure all vegetables are cut to a similar size for even cooking.
- For extra flavor, toss in some minced garlic with the vegetables before roasting.
- If you enjoy a bit of crunch, you might want to roast the tomatoes separately, adding them towards the end.
- Customize your seasoning by incorporating herbs like rosemary or thyme for an added aromatic touch.
- Leftover roasted vegetables are fantastic in wraps or as a colorful topping for pizzas.

Recipe FAQs
Can I use frozen vegetables instead of fresh?
Yes! Frozen vegetables can be roasted, but they often contain more moisture, making them softer. Be sure to spread them out well and roast a bit longer to achieve the desired crispness.
How do I know when the roasted vegetables are done?
Your roasted vegetables should be tender and have a slightly caramelized, golden brown color on the edges. If you’re unsure, a fork should easily pierce through them without much resistance.
Is there a way to make this dish ahead of time?
Absolutely! You can pre-chop your vegetables a day in advance and store them in the fridge. Just toss them with the oil, salt, and pepper right before roasting for the best flavor and texture.
Can I add other vegetables or seasonings?
Go for it! This basic recipe is flexible. Feel free to add root vegetables like sweet potatoes or beets, and experiment with different herbs and spices to find your favorite combination.
