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. Additionally, it’s 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 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. 🌶 🥦 🥕

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.
  • In this recipe I used broccoli, cauliflower, thin baby carrots, red bell pepper, onions, and mushrooms. 
  • When roasting vegetables, I usually don’t even bother with measuring; I just layer every veggie I can find on top of a sheet pan lined with parchment paper.
  • Then, I take a little olive oil and drizzle it all over. Next, I add salt, black pepper, garlic powder, and Italian seasoning over the veggies.
  • Using my hands, I mix up everything together until all the veggies are coated with oil and seasonings.
  • Finally, I transfer the vegetables to the oven for about 17 to 20 minutes at high heat, or until crisp-tender and lightly browned. 

That’s pretty much IT. It is healthy and tasty, and you only need a handful of simple ingredients to make the best side dish. Add your favorite protein, and it’s an easy way to make this a delicious full course!

Tips For Perfectly Roasted Vegetables

  • Do not overlap the veggies. You want one single layer of vegetables. I advise using a large sheet pan – 12 x 16 is a good size. 
  • Stir the veggies halfway through cooking. 
  • Use your favorite seasonings and spices, toss in fresh herbs and chili powder, and adjust the amounts to your preference.
  • 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 like a SOFT tender veg. Thus, since majority rules… we end up with crisp-tender vegetables. 😉 
  • Before serving, add grated parmesan cheese and fresh chopped parsley. A drizzle of balsamic vinegar is also a delicious idea.

Recipe Variations and Vegetable Swaps

  • 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.
  • 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 dice them 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 Vegetables Leftovers

  • 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.
