The Best Oven Roasted Vegetables

Enjoy a delicious and easily prepared recipe for oven roasted vegetables ready in just 20 minutes! This perfect side dish pairs wonderfully with meat, fish, or rice, offering a healthy and tasty addition to any meal. It’s also an ideal option for meal prep: roast several large sheet pans of veggies on Sunday night and then conveniently reheat them for quick and nutritious lunches or dinners throughout the week!

This awesome roasted vegetables recipe has been my go-to dish lately because I can’t pass up a Farmer’s Market if my life depended on it. I see a veggie/fruit/pumpkin stand, and I STOP! I just hop out of the car, take everything they’ve got on display, and continue on my journey.

I live in Indiana, friends. Farmer’s Markets last a whole, what, like, 3 months around here?! So, I just take full advantage. 🌶 🥦 🥕

Ingredients You’ll Need

For these delicious oven roasted veggies, we’re using basic ingredients that pack a punch of flavor. This Italian seasoned recipe combines the perfect blend of fresh vegetables and simple seasonings.

  • Broccoli florets & cauliflower florets: Broccoli and cauliflower are the perfect oven roasted veggies when you’re looking for a satisfying, tender crunch.
  • Baby portobello mushrooms: Brings an umami flavor that deepens the overall taste of the dish. Substitute with cremini mushrooms.
  • Baby carrots: Add a natural sweetness and vibrant color. You can use sliced regular carrots.
  • Red bell pepper: Contributes a sweet flavor and a crisp tender texture. You can also use yellow, orange, or green bell pepper.
  • Yellow onion: Red or white onion are good alternatives.
  • Olive oil: Helps to coat the vegetables for even roasting. I also like to use avocado oil sometimes or even vegetable oil.
  • Salt and pepper: Enhances the natural flavors of the vegetables.
  • Italian Seasoning: Provides a blend of herbs that adds flavor, but you can use any of your favorite dried seasonings. Herbes de Provence is a good one here.
  • Garlic powder: I mostly use fresh garlic in my cooking, but in this roasted vegetables recipe, I think it’s best to go with garlic powder.
  • Grated parmesan cheese: Optional garnish that adds a salty, nutty flavor and enhances the dish’s overall taste.
  • Chopped fresh parsley: I use parsley for a simple garnish to add freshness and a touch of color. Fresh basil or cilantro would also work.

How To Make Oven Roasted Vegetables

Roasting vegetables is an easy and very simple, almost hands-off skill. Vegetables are nutritious food to feed yourself and your family, and roasting them is one way to make those veggies wanted, demanded, and loved by picky eaters. The hot oven brings out the natural sugars in vegetables, resulting in a sweet and fantastic depth of flavor. Besides, this is the best way to clean out that vegetable tray in your fridge.

Broccoli florets, cauliflower florets, baby carrots, red peppers, onions, and mushrooms are arranged on a sheet pan.
  1. Prepare the Vegetables: In this recipe, I used broccoli, cauliflower, thin baby carrots, red bell pepper, onions, and mushrooms. When roasting vegetables, I usually don’t bother with measuring; I just layer every veggie I can find on top of a sheet pan lined with parchment paper.
  2. Season the Vegetables: Drizzle a little olive oil over the veggies, then add salt, black pepper, garlic powder, and Italian seasoning.
  3. Mix and Coat: Using my hands, I mix everything together until all the veggies are coated with oil and seasonings.
  4. Roast in the Oven: Transfer the vegetables to the oven and roast at 425˚F for about 17 to 20 minutes, or until they are crisp-tender and lightly browned.

That’s pretty much it! This roasted veggies in oven recipe is healthy and tasty, and requires only a handful of simple ingredients to create the perfect side dish. Add your favorite protein, and you’ve got an easy and delicious full course meal!

Tips For Perfectly Roasted Vegetables

Whether you’re looking for a quick side dish or a healthy snack, these roast veggies will become a staple in your kitchen. To ensure perfect results every time, check out these simple yet effective tips to take your vegetables to the next level.

  • Even cooking. When oven roasting, do not overlap the veggies. You want one single layer of vegetables so they cook evenly, and so they roast and not steam. I advise using a large sheet pan – 12 x 16 is a good size. 
  • Stir midway. Stir the veggies halfway through cooking. 
  • Season to taste. Use your favorite seasonings and spices, toss in fresh herbs and chili powder, and adjust the amounts to your preference.
  • Check for doneness. Continue roasting until the vegetables are easily pierced with a fork or knife and they are showing crispy, charred bits at the edges. I like my veggies crisp-tender. The other three in this household love a soft tender veg. Thus, since majority rules… we end up with crisp-tender vegetables. 😉 
  • Final touches. Before serving, add grated parmesan cheese and fresh chopped parsley. A drizzle of balsamic vinegar is also a delicious idea.

Variations and Vegetable Swaps

  • Vegetable options. You can use different vegetables than what is listed as long as the vegetable/s can cook in around 15-20 minutes at 425˚F. For example, you can use asparagus, green beans, halved small Brussels sprouts, quartered red onion, or sliced zucchini.
  • Root vegetables. I recommend avoiding sweet potatoes or other root vegetables as they generally require a longer cooking time. However, if you prefer to include them, simply cut the vegetables into smaller pieces. This adjustment will help them roast more quickly, allowing them to cook in roughly the same timeframe as the other vegetables.

Storing Leftover Roasted Veggies

Store completely cooled vegetables in an airtight container, and keep in the fridge for up to 4 days. To keep the vegetables firm and crisp, reheat them in a preheated 450˚F oven for 5 minutes.

Frequently Asked Questions

What temperature is best for roasting vegetables?

The best temperature for roasting vegetables is 425°F. This allows the vegetables to caramelize nicely while becoming tender and flavorful.

Do you roast vegetables in the oven covered or uncovered?

Roast vegetables in the oven uncovered. This helps them achieve a nice browning and keeps them crisp rather than becoming steamed.

Should I use foil or parchment paper?

You can roast vegetables using foil or parchment paper. Both options prevent the veggies from sticking to the baking sheet and make cleanup easier.

    Very good. Did not use bell peppers but everything else the same. Cooked mushrooms separate. Brocolli cooked faster than other vegetables so removed them from the pan early. Will make again

    1. Katerina says:

      Glad to hear you enjoyed it! Adjusting for the different cooking times of the veggies sounds like a great idea. Thanks for sharing your tips, and happy cooking! 😊🍽️

  2. Denise says:

    Awesome, easy and low calorie

    1. Katerina says:

      Thank YOU! I am very glad you enjoyed it! 🙂

  3. Erica says:

    I am making these tonight! I am going to add squash and zucchini. I have 1 of each in the frig that needs to be cooked. I’m pairing mine with rice pilaf and roasted chicken.:)

  4. Jenn says:

    Absolutely delicious! You have alleviated my fear of screwing up the roasted veggies lol!!

  5. Lisa says:

    The recipe itself was super tasty, but the instructions said it takes 17 – 20 minutes to roast. I followed the instructions to a tee and it took over an hour for the veggies to get tender. I planned my whole meal around this and was super late and behind due to how long it took the veggies to actually cook.

    1. Katerina says:

      Thank you for trying the recipe and for your feedback. I’m sorry to hear that the cooking time didn’t align with your expectations. It’s quite unusual for the vegetables to take an hour to roast at 425°F. Could I ask about the type and size of the cut vegetables you used? Did you separate the cauliflower and broccoli into florets and cut up the peppers, carrots, etc., as per the recipe? Thanks again for your input!

      In the construction world where I work, we call this “operator error”.When a worker is provided with a bulldozer (recipe) to use but doesn’t follow safe operating procedures,the accident (unsatisfactory results) is on the “operator” of bulldozer not the bulldozer.

      1. Jeff d says:

        My Jan 13th 2024 comment was a response to Lis Dec 12th 2024 comment.Not that anyone cares,lol

        1. Katerina says:

          I care!! 🙃 And thank you! 🙏

  6. Jan La Grange says:

    May I pls ask what brand of Italian seasoning you use? I’ve tried a couple that were hit and miss and I’m sure you’d know better than I! Looking forward to making this. Love your site!!


    Can you make this ahead of time and reheat it it microwave?

    1. Katerina says:

      Yes. Let the veggies cool to room temperature and then store them in an airtight container and keep them in the fridge. To keep the vegetables firm and crisp, reheat them in a preheated oven at 450˚F for 5 minutes.
