Follow The Directions

01

Step

Preheat the oven to 450 degrees F (230 degrees C). (5 minutes)

02

Step

In a large bowl, combine the cauliflower florets, mushrooms, garlic, red onion, red bell pepper, and yellow bell pepper. Drizzle with olive oil and balsamic vinegar. Season generously with sea salt and freshly ground black pepper. Toss well to ensure all vegetables are evenly coated. (5 minutes)

03

Step

Transfer the mixture to a 2-quart baking dish, spreading the vegetables in a single layer for optimal roasting. (2 minutes)

04

Step

Roast in the preheated oven until the cauliflower is tender and slightly caramelized, approximately 30 minutes. Stir halfway through for even browning. (30 minutes)

05

Step

Remove from oven and serve immediately, garnished with fresh herbs if desired.

For a deeper flavor, consider adding a pinch of red pepper flakes or a sprinkle of dried oregano to the vegetable mixture before roasting.
Roasting time may vary slightly depending on the size of the cauliflower florets and the oven. Check for doneness by piercing a floret with a fork – it should be tender but not mushy.
This dish is also delicious served cold or at room temperature, making it a perfect addition to a buffet or potluck.
