Ingredients:

  • 1 lbs Waxy Potatoes (e.g., Yukon Gold or Maris Piper), scrubbed and quartered
  • 5 lbs Carrots, peeled and cut into 1-inch chunks
  • 6 lbs Broccoli Florets, bite-sized
  • 1 large Red Onion, cut into 8 thick wedges
  • 1 large Red Bell Pepper, chopped into 1-inch squares
  • 5 Tbsp Neutral Oil (e.g., Avocado or Light Olive Oil)
  • 2 tsp Fresh Rosemary, finely chopped
  • 1 tsp Fresh Thyme, leaves only
  • 4 large Garlic Cloves, smashed or minced
  • 1 Tbsp Kosher Salt (Flaky)
  • 1 tsp Freshly Ground Black Pepper
  • ½ medium Lemon (optional, for finishing)

Instructions:

  1. Preheat the oven to a scorching 425°F (220°C). Position the rack in the middle and line two large rimmed baking sheets with parchment paper.
  2. Chop all vegetables to approximately the same size (1 to 1.5 inches) for even cooking. Ensure the vegetables are dry—pat them down with a clean tea towel if they were recently washed.
  3. In a large mixing bowl, toss the 'hardy mix' (potatoes and carrots) with 3 Tbsp of oil, half of the salt, pepper, half of the herbs, and half of the garlic.
  4. Toss the remaining 'tender mix' (broccoli, onion, and pepper) separately with the remaining oil, seasoning, and herbs.
  5. Arrange the hardy mix on one baking sheet and the tender mix on the second. Crucially, ensure the vegetables are in a single layer with airspace between them to prevent steaming.
  6. Place the hardy mix tray in the oven first. Roast for 15 minutes.
  7. After the initial 15 minutes, add the tray with the tender mix to the oven.
  8. After another 15 minutes (30 minutes total cook time for the potatoes), carefully remove both trays. Use a spatula to scrape and turn the vegetables to expose new surfaces to the pan. Return to the oven.
  9. Roast for a final 5–10 minutes. The vegetables are ready when the potatoes are fork-tender and the broccoli/carrots have deeply caramelised, crispy edges.
  10. Remove from the oven. If desired, squeeze the juice of half a lemon over the hot vegetables. Taste and adjust seasoning with flaky sea salt. Serve immediately.
