How To Make Rainbow Roasted Vegetables

PRO TIP  This recipe is so easy to whip up and put in the oven, especially if you prep and chop ingredients ahead of time! 

Remember to preheat oven to 415 degrees F and line a large rimmed baking sheet with foil and spritz with non-stick spray.

PREP VEGETABLES  In a large bowl combine the diced sweet potato and cauliflower and toss with 1 tbsp olive oil, ½ tsp salt and ¼ tsp black pepper. Toss to coat and then spread into an even layer on the baking sheet. Roast for 10 minutes. Stir the potatoes and cauliflower and then push to one side of the pan. 

These veggies need a bit longer to roast than the others to ensure a tender roast! 

PREP QUICK ROASTING VEGGIES  Combine the remaining vegetables in the same large bowl and toss with 1 tbsp olive oil, ½ tsp salt, ¼ tsp black pepper, ½ tsp garlic powder, ½ tsp onion powder and ½ tsp Italian seasoning.

MIX TOGETHER  Add the seasoned vegetables to the pan with the sweet potato and cauliflower, making sure to give all the vegetables plenty of room, allowing them to roast evenly. Continue roasting for an additional 15 to 20 minutes, stirring the vegetables again halfway through, until they are tender.

GARNISH  After all of the veggies are finished baking, remove from the oven and garnish with the freshly chopped parsley. Enjoy! 

Can I Roast Frozen Vegetables?

The short answer is NO, you should not roast frozen vegetables.

When vegetables are frozen and then defrosted, they tend to lose a lot of moisture in the process. You’ll end up with a less than desirable texture. 

Your best bet is to use fresh veggies when roasting. 

Tips and Variations

Here are a few tips along with my favorite ways to switch up the recipe to customize it the way my family likes it. 

• If you have all the ingredients prepped in the fridge before you make it, it comes together SO quickly. Prep ahead! 
• Want spicy? Add a few sprinkles of red pepper flakes to kick up the spice level! 
• Add lemon  or serve with lemon wedges for a little pop of flavor right before serving. 

What is the Difference Between Roasting and Baking Vegetables? 

It depends on the foods being cooked and the temperature it’s being cooked at. 

Roasting requires higher baking temperatures for the duration of the cooking process. 
Baking  happens at a lower temperature for a longer amount of time, usually about 375 F or below.
