Pro Tips

• Don’t Overcrowd the Basket: For the best crispy, golden-brown results, arrange the fennel in a single layer. Cook in batches if necessary to ensure hot air can circulate properly.
• Uniform Slicing: Cut fennel wedges to a uniform thickness (about 1/2 inch) to ensure they cook evenly and achieve the perfect tender-crisp texture.
• Toast the Seeds: For a deeper, nuttier flavor, toast the sunflower seeds in a dry pan for 2 minutes until fragrant before sprinkling them over the finished dish.
• Save the Fronds: Don’t discard the feathery fennel fronds! Chop them up and use them as a fresh, herb-like garnish for a pop of color and mild anise flavor.

FAQ

Q: What does air fryer roasted fennel taste like
A: When roasted in the air fryer, fennel becomes tender and sweet with a delicious caramelized flavor. The strong licorice or anise taste mellows significantly, making it appealing even to those who don’t typically enjoy raw fennel. The edges get delightfully crispy, adding a wonderful texture.

Q: How do I get my fennel crispy in the air fryer
A: The key to crispy fennel is to avoid overcrowding the air fryer basket. Arrange the fennel wedges in a single layer to allow hot air to circulate freely. If needed, cook in batches. Slicing the wedges to a uniform 1/2-inch thickness also ensures they cook evenly and achieve the perfect tender-crisp texture.

Q: What can I serve with this keto fennel side dish
A: This versatile low-carb side dish pairs wonderfully with a variety of main courses. It’s an excellent accompaniment to roasted chicken, grilled fish like salmon, seared steak, or pork chops. Its unique flavor complements almost any protein.

Q: Can I use the whole fennel bulb for this recipe
A: Yes, you can use most of the fennel. This recipe uses the bulb, cut into wedges. You should also save the feathery fronds! They can be chopped and used as a fresh, herb-like garnish to add a pop of color and mild anise flavor to the finished dish.
