A quick and easy method to roast frozen mixed vegetables with garlic-infused olive oil, resulting in crispy, flavorful veggies perfect for weeknight dinners.

Ingredients

Scale
  • 4 cups (about 600g) frozen mixed vegetables (broccoli, cauliflower, carrots, green beans)
  • 3 tablespoons garlic-infused olive oil (or plain olive oil plus 2 minced garlic cloves)
  • 1 teaspoon sea salt
  • ½ teaspoon freshly ground black pepper
  • ¼ teaspoon red pepper flakes (optional)
  • Zest of ½ lemon (optional)

Instructions

  1. Preheat your oven to 425°F (220°C) and allow it to heat fully for 10-15 minutes.
  2. Prepare a rimmed baking sheet by lining it with parchment paper or lightly greasing it.
  3. In a large mixing bowl, toss 4 cups of frozen mixed vegetables with 3 tablespoons of garlic-infused olive oil until well coated.
  4. Add 1 teaspoon sea salt, ½ teaspoon freshly ground black pepper, and optional ¼ teaspoon red pepper flakes. Toss again to distribute seasonings evenly.
  5. Spread the vegetables out evenly in a single layer on the baking sheet to avoid steaming.
  6. Roast for 20 minutes on the center rack, flipping the vegetables halfway through after 10 minutes using a spatula or tongs.
  7. Check for doneness; edges should be golden and crispy, insides tender. Roast an additional 5 minutes if a crispier texture is desired, watching closely to avoid burning.
  8. Remove from oven and sprinkle the zest of half a lemon over the vegetables.
  9. Serve immediately while hot and crispy.

Notes

Do not thaw the vegetables before roasting to avoid sogginess. Flip the vegetables halfway through roasting for even browning. If veggies release excess water, pat dry before tossing with oil. For a lower-fat version, use light olive oil but flavor will be less rich. Can be roasted in a cast iron skillet for extra crispiness. Reheat leftovers in the oven at 400°F for 5-7 minutes to regain crispness; avoid microwaving.
