Preheat oven to 400°F. Line a large baking pan with parchment paper. Drizzle or brush it with 1 tablespoon of olive oil.
Slice fennel into ½-1/4 thick rounds. Carefully, place fennel slices on a prepared pan. Drizzle with the remaining oil. Season the tops with salt, pepper and garlic powder. Flip the slices, and season the other side as well. Sprinkle with some fresh thyme leaves and grated Parmesan cheese on top.
Bake for about 20 minutes or until the fennel is tender and the cheese is golden brown. Remove from the oven and enjoy.
Notes
You can store roasted fennel in the fridge for up to 3 days.Reheat it in the microwave or oven.You can easily make it vegan, but adding more seasonings and skipping the cheese. You can also use the nutritional yeast instead of cheese.If you like more anise flavor, save the green fronds and use them to garnish the dish before serving.
