Best Vegetables for Roasting

  • Hearty Vegetables (Best Choice): This recipe uses hearty root vegetables (potatoes, carrots, parsnips, sweet potatoes) and Brussels sprouts. These are the best for roasting at 400°F as they become tender on the inside and caramelized on the outside.
  • Softer Vegetables: You can also add softer vegetables like bell peppers, zucchini, or broccoli, but they cook faster. Add them to the pan during the last 20 minutes of roasting.

Storage and Freezing Tips

  • To Store: Store leftover roasted vegetables in an airtight container in the refrigerator for 3-4 days.
  • To Reheat: For best results, spread vegetables on a baking sheet and reheat in a 400°F (200°C) oven or in an air fryer for 5-10 minutes until hot and re-crisped.
  • To Freeze: Yes, you can freeze roasted vegetables. After cooking, let them cool completely. Flash-freeze by placing them on a baking sheet in the freezer for about two hours. Once frozen, transfer the vegetables to an airtight container or freezer bag.

Ingredient Substitutions

Try any of these flavorful seasoning options to add variety to your roasted veggies:

For a tangy flavor, whisk 2 tablespoons of balsamic vinegar and 2 minced garlic cloves with the olive oil before tossing.

After roasting, toss the warm vegetables with 1/4 cup of fresh chopped parsley or basil for a burst of fresh flavor.
