Ingredients

  • 1 small head purple cauliflower
  • 1 small head orange cauliflower (or orange bell pepper, if unavailable)
  • 1 small head green cauliflower (or Romanesco broccoli as a substitute)
  • 1 small head white cauliflower
  • 3 tbsp extra virgin olive oil
  • 2 cloves garlic, minced
  • 1 tsp smoked paprika
  • 1 tsp ground cumin
  • ½ tsp turmeric powder
  • Salt and freshly ground black pepper to taste
  • 2 tbsp freshly chopped parsley
  • 1 tbsp lemon juice
  • Optional: ¼ cup toasted pine nuts or slivered almonds for garnish

Equipment

  • Baking sheet or roasting pan
  • Large mixing bowl
  • Sharp knife and cutting board
  • Measuring spoons
  • Garlic press or mortar and pestle (optional)
  • Oven mitts
  • Spatula or tongs
  • Serving platter or bowl

Instructions

  1. Preheat your oven to 425°F (220°C). Line your baking sheet with parchment paper or lightly grease it with olive oil to prevent sticking.
  2. Prepare the cauliflower: Rinse each cauliflower head under cold water and pat dry. Cut the cauliflower into bite-sized florets, keeping the colors separate to preserve their vibrancy.
  3. Make the seasoning blend: In a large mixing bowl, combine the extra virgin olive oil, minced garlic, smoked paprika, ground cumin, turmeric, salt, and pepper. Stir until well mixed.
  4. Toss the cauliflower: Add the florets of all colors into the bowl with the seasoning blend. Gently toss until all florets are evenly coated with the oil and spices.
  5. Arrange on baking sheet: Spread the seasoned florets out in a single layer on your baking sheet, ensuring they have space to roast rather than steam.
  6. Roast the cauliflower: Place the baking sheet in the preheated oven and roast for 20-25 minutes, turning the florets halfway through to ensure even browning.
  7. Check for doneness: The cauliflower should be tender when pierced with a fork and have caramelized edges. If desired, you can roast a few extra minutes for added crispness.
  8. Finish and garnish: Remove the cauliflower from the oven. Drizzle with fresh lemon juice and sprinkle with chopped parsley. Add toasted pine nuts or slivered almonds for a delightful crunch.
  9. Serve warm: Transfer the roasted rainbow cauliflower to a serving platter and enjoy immediately as a side dish or part of a larger meal.

Tips & Variations

“To keep the colors bright, avoid boiling the cauliflower before roasting. Roasting raw florets locks in both flavor and color!”

  • Make it vegan-friendly: This recipe is naturally vegan, but be sure to check any garnish or additional toppings for animal products.
  • Spice it up: Add a pinch of cayenne pepper or chili flakes to the seasoning blend if you like a little heat.
  • Try different herbs: Swap parsley for fresh thyme, rosemary, or dill to change the flavor profile.
  • Add cheese: For a richer taste, sprinkle crumbled feta or grated Parmesan before serving.
  • Use frozen cauliflower: If fresh rainbow cauliflower is hard to find, you can use frozen mixed cauliflower; just adjust roasting time accordingly.
  • Serving as a salad: Toss the roasted cauliflower with cooked quinoa, chickpeas, and a tahini dressing for a colorful grain bowl.
