Why We Love Roasting Our Vegetables

  1. Roasting is simple - toss the vegetables in oil and seasoning, then let the oven do the work.
  2. Once vegetables are in the oven, you have time for other things to do, making it a very convenient cooking method.
  3. Roasting results in a nice combination of tender interiors and slightly crispy exteriors, adding a delightful contrast in texture.
  4. Roasted vegetables look great with their bright colors and caramelized edges.
  5. Roasted vegetables can be made in large batches and used for meal prep, making the next few lunches or dinner easy to pull together.

  • Preheat the oven to 400 degrees F or 204 degrees C.
  • Wash and dry vegetables.
  • Cut veggies into even-sized pieces.
  • Toss vegetables with olive oil. Make sure each piece is lightly coated with oil, not drenched.

  7. Oven mitt

Our favorite salt for roasting veggies is from Oryx. Oryx refillable salt grinder is excellent salt for roasting vegetables. The salt is from the Kalahari Desert and has a clean taste. It's free from additives and anti-caking agents.

Why Should I Use Parchment Paper?

Using parchment paper for roasting vegetables simplifies the cooking process.

Parchment paper prevents sticking and helps improve the overall quality of your roasted vegetables. It's a handy kitchen tool that can make your cooking experience more convenient and enjoyable.

Do I Need Organic Vegetables?

You can roast organic vegetables using the same method as conventional ones. If you have the option and budget permits, opt for organic varieties.

I enjoy farmers' markets for their fresh produce. Whole Foods Market is also an excellent source of high-quality organic produce.

The Best Veggies for Roasting

The best vegetables for roasting are the freshest ones. They should be free from dents, black spots, soft spots, or signs of decay.

The firmness or water content of the vegetables you're roasting will determine how to slice and dice them.

  • Root vegetables: white potatoes, sweet potatoes, parsnips, carrots, radishes, and beets are all good vegetables to roast.
  • Long vegetables: asparagus, green beans.
  • Squash: Butternut squash, spaghetti squash, delicata, honeynut, kabocha, acorn squash, etc.
  • Peppers: Bell peppers or chili peppers, i.e. jalapeno, serrano, poblano, etc.
  • Alliums: Garlic, white, yellow, red onion, or scallions. shallots, leeks, chives.
  • Cruciferous vegetables: broccoli, cabbage, cauliflower, turnips, Brussels sprouts, bok choy.
  • Leafy vegetables: purple cabbage, green cabbage, kale.

Seasonings for Roasted Vegetables

These are the recipes we regularly enjoy at home, most of them prepared with simple seasonings like salt and pepper. Occasionally we add whole or smashed cloves of garlic for extra flavor.

In the last 10 minutes of roasting, you can add a sprinkling of cheese. Parmesan, Romano and cheddar are all great options.

Experiment with seasonings by incorporating chili powder and cayenne, along with garlic powder, or even a little cinnamon. To add freshness and flavor, try adding fresh herbs. Chopped cilantro and parsley work well after you take it out of the oven.

I even add homemade blackened seasoning before roasting vegetables sometimes. It adds spice and a little smoky flavor to the food.

  2. Uniform Cuts: Cut vegetables into similar-sized pieces for consistent cooking times.
  3. Seasoning: Season vegetables with salt and pepper, and experiment with additional flavors like fresh herbs, garlic, and honey.

Roasting vegetables at 400°F is our magic number! This temp unlocks crispy perfection with golden caramelization outside and juicy goodness within.

Achieving perfectly roasted vegetables can be the game-changer you need. Roasting your veggies at 400 degrees F hits the sweet spot, ensuring delicious dishes without scorching temps.
