Oven Roasted Vegetables

Oven Roasted Vegetables are a family favorite! This vegetable medley of zucchini, mushrooms, tomatoes, onions is simple, quick & delicious. 

Mmmm,  roasted vegetables. Roasting vegetables is one of the best ways to bring out a whole new flavor profile. A rich, deep earthy flavor that you just don’t get with raw vegetables.

Oven Roasted Vegetables are such a great compliment to any meal and they are pretty darn good for you too. One of the best things about roasted veggies is that you can pick and choose what kinds of vegetables you like, apply the same technique and you will get very yummy results. For this recipe, I roasted crimini mushrooms, zucchini, tomatoes, onions and a little garlic.

Not only are roasted vegetables quick, easy and delicious but aren’t they also pretty gorgeous? Just look at all of those colors! 

Ingredients you’ll need: 

Like I mentioned above, you can use a different medley of vegetables but for this recipe, I used one of my favorite combos. 

Oven roasted vegetable ingredients.
  • CRIMINI MUSHROOMS: Sometimes also called baby bella,  I prefer crimini mushrooms to white button mushrooms because they tend to be more flavorful. 
  • ZUCCHINI: You’ll need just one of two zucchini depending on the size. I used 2 medium sized zucchini.
  • CHERRY TOMATOES: You could also use grape tomatoes or any other bite size tomato and get the same result. 
  • RED ONION: Roasting red onion turns this bitter, pungent vegetable into a mild sweet addition to these vegetables. Plus the color is pretty too! 
  • GARLIC: I love adding garlic to roasted vegetables. It gets a mildly sweet garlicky flavor. I used 5 cloves in this recipe but you could certainly use more or a little less. 
  • OLIVE OIL: Because we are roasting at a low temperature, you can use olive oil and not risk 
  • SALT AND PEPPER: We want the flavor of each of the vegetables to shine so we don’t need a bunch of seasonings to make them delicious. A little salt and pepper is all you need! 
  • PARSLEY: For a pop of bright green color and a bit of freshness!

Step by Step Photos and Instructions: 

Roasting vegetables in the oven is probably one of the easiest side dishes you can make! One of the biggest keys is to make sure that each vegetable is roughly the same size. This helps them cook a bit more evenly.

All of the vegetables in this recipe have a pretty high water content, so I like to turn on the broiler for a few minutes to allow some of the water to evaporate and give the vegetables a bit of char. 

  • Step #1: Preheat oven to 325 degrees F. 
  • Step #2: In a large bowl combine all of the veggies.  Add minced garlic. Drizzle with olive oil and season with salt and pepper. Toss to coat completely. 
  • Step #3: Spread veggies out in a single layer on a baking sheet. Bake in preheated oven for 20 – 25 minutes. Use a turner/spatula to turn over the veggies. Turn on the broiler and broil for 3 – 5 minutes or until most of the water evaporates and the veggies start to get charred in places. Sprinkle with parsley and serve immediately. 

Storage and Leftovers: 

Oven Roasted Vegetables are best eaten the day that they are made. They will lose a quite a bit of their texture if they are reheated.

Don’t you just love how colorful these are and how easy they come together? This makes Oven Roasted Veggies the perfect vegetable side dish for even the busiest of weeknights. These would be great with Lemon Pepper Chicken and Garlic Rice.

Here are some other favorite vegetable side dishes:

Southern Style Green Beans with Bacon are slow cooked green beans perfect for your Sunday dinner.

These Smashed Brussels Sprouts will make a brussels sprouts lover out of just about anyone!

Sautéed Broccoli is a classic, easy vegetable side dish.

Ingredients:

  • 10 large crimini mushrooms quartered
  • 2 medium zucchini halved lengthwise and then sliced
  • 5 cloves garlic minced
  • 15 cherry tomatoes halved
  • 1/2 red onion chopped (not to small,try to keep them the same size as the other veggies)
  • 2 tablespoons extra virgin olive oil
  • 1 teaspoon kosher salt
  • 1/2 teaspoon black pepper

Instructions
 

  • Preheat oven to 325 degrees.
  • Toss veggies with garlic, salt, pepper and extra virgin olive oil.
  • Roast on a baking sheet. Turn after 15 minutes. Turn on the broiler and cook 3 - 5 minutes or until the liquid evaporates and the vegetables start to char in places. Sprinkle with parsley and serve immediately.

Notes

All of the vegetables in this medley have a high water content, turning on the broiler at the end will help get rid of some of the excess water and give the vegetables a bit of a char. So I highly recommend that step!

    Hi Deseree,

    I’ve been reading your blog for about a year or so and have been drooling over everything that you make. I finally made something- the oven roasted vegetables and they were DELICIOUS. So simple and so good. My boyfriend and I devoured them. I made this w/ the lemon pepper chicken from your site and it was a great meal. I hope you have a great New Years and thank you for your blog!

      Hi Carolyn,
      Thank you for following the blog for so long! I am happy to hear that the vegetables and chicken that you made were a great meal. I’ve never made the two together but it seems like it would be a winning combination. I hope you have a great New Year’s too! :)
