How to Make the Best Garlic Parmesan Roasted Vegetables Recipe

Some days I feel like when I open my fridge I have bits and pieces of ingredients that aren’t necessarily enough when cooked alone but they form a delicious paring with other ingredients. That’s precisely how this mixed vegetable medley along with my Vegetable Beef Soup have evolved into some of our most favorite clean out the fridge dishes.

  • Ingredients you’ll need to make homemade Garlic Parmesan Roasted Vegetables: Fresh cauliflower florets, broccoli florets, baby carrots, red onion, olive oil, grated Parmesan cheese, garlic salt, red pepper flakes, dry Italian seasoning, melted butter and chopped fresh Italian parsley for garnishing.
  • Kitchen gadgets you’ll need: A colander to wash the vegetables, a sharp knife and chopping board, two standard sheet pans or an extra large baking pan, a mixing bowl, measuring cups and spoons and a Parmesan cheese grater.
  • You can clean and prep all of the vegetables in advance and pack them into Ziploc bags then store in the refrigerator. Doing so will have them ready to toss with olive oil and Parmesan cheese just before roasting.
  • It’s important to evenly toss the vegetables with the seasonings before arranging in a single layer on the baking pan.
  • When arranging the vegetables on the pan, allow room for air to circulate. You don’t want to stack them or they’ll steam. They should be in a single layer so that each vegetable comes into contact with the pan.
  • You can line the sheet pan with aluminum foil sprayed with cooking spray for easy clean-up.
  • For this vegetable medley you have the opportunity to personalize it to your taste using what you have on hand.
  • Parsnips would be a great addition as well as any variety of colorful bell peppers, fresh mushrooms or blanched red potatoes. I always love any dish that fills-up my family and saves grocery money, too.
  • Store leftover roasted vegetables chilled in the refrigerator for up to 3-4 days. Reheat in the microwave.

  1. I’m making it now – it is baking as we speak. I had the cauliflower, broccoli and carrots but no idea on what I could do with them to accompany roasted chicken thighs. Steaming is so boring. So I had all the stuff and I’m jazzed ! Thx ! I have no doubt it going be perfect.

    I’ve made a version of this many times (mine doesn’t have butter, red pepper flakes, or Italian seasoning… though Italian seasoning sounds yummy) and is Delicious over couscous (or quinoa seasoned with butter, salt, pepper). It’s so easy, give it a try!!

  3. 5 stars
