Gather the ingredients

You can find the list of the ingredients and their quantities in the recipe card below.
I recommend looking for smaller bulbs of fennel as they tend to be more tender and sweeter.
You will also need freshly Grated Parmesan, olive oil, salt, black pepper, garlic powder and some thyme.
How to make roasted fennel with Parmesan cheese

Step 1. Wash, trim the roots, fronds , stalks, and remove the outer layer of the fennel bulb.
Quick note: I remove the core only if the fennel bulb is large. Small ones have tender cores.
Step 2. Slice the fennel bulb thinly into rings, similar to how would you do it with the onion.
Step 3. Drizzle olive oil on a pan lined with some parchment paper. Place thin fennel slices on top. Drizzle them with more oil on top. Season each fennel slice with salt, pepper, garlic powder, and some fresh thyme leaves. Flip the slices, and season the other side as well. Sprinkle each fennel slice generously with grated Parmesan cheese.
Step 4. Roast fennel at 400 f degrees for about 20 minutes or until it is tender and the cheese on top is golden brown.
Recipe tip
Cut the fennel into ½ to ¼ inch thick slices and use a generous amount of oil to prevent drying out, ensuring it comes out tender inside with caramelized edges.
Frequently asked questions
Yes, the whole fennel is edible, including the bulb, stalks, and green fronds. The green, feather-like fronds are great for salads or garnishing. Some people prefer to cut out the fennel core, but I only do this if the bulb is large. Otherwise, I leave the core in because it becomes tender when cooked.
Yes, you can follow the same recipe directions and air fry fennel at 375 for about 8 minutes or until tender and the cheese is golden brown.
Roasted fennel with Parmesan cheese tastes best when freshly made. The recipe is very easy and quick, and if you need to prepare it ahead of time, I recommend slicing the fennel half an hour in advance and keeping it in the fridge in an airtight container until ready to cook.
