1. Preheat your oven to 400°F (200°C).
2. Wash the cauliflower thoroughly and remove the outer leaves. Cut the cauliflower into florets, ensuring they are roughly uniform in size so they cook evenly.
3. In a large mixing bowl, toss the cauliflower florets with olive oil until they are evenly coated.
4. Season the cauliflower with salt, pepper, and any optional seasonings or spices you desire, such as garlic powder, paprika, or grated Parmesan cheese. Mix well to ensure the seasoning is evenly distributed.
5. Arrange the seasoned cauliflower florets in a single layer on a baking sheet lined with parchment paper or aluminum foil. Make sure there is some space between the florets to allow for even cooking.
6. Place the baking sheet in the preheated oven and bake for 20-30 minutes, or until the cauliflower is tender and golden brown on the edges. You can check for doneness by inserting a fork into the thickest part of a floret : it should pierce easily.
7. Once the cauliflower is cooked to your liking, remove it from the oven and transfer it to a serving dish. Squeeze some fresh lemon juice over the top for a bright, citrusy flavor, if desired.
8. Garnish with fresh herbs like parsley or thyme for added freshness and color.
9. Serve the baked cauliflower hot as a delicious side dish or as a main course. Enjoy!
