Pro Tips

• Grate Your Own Cheese: Pre-shredded cheese contains anti-caking agents that prevent smooth melting. For the gooiest, meltiest results, always grate a block of cheddar yourself.
• Pat Cauliflower Dry: After washing, pat the florets completely dry. Removing excess water is key to preventing a watery sauce and achieving a rich, velvety consistency.
• Watch for Browning: Air fryers cook intensely from the top. If the cheese gets too dark too fast, loosely cover the pan with foil for the remaining cook time.
• Let It Rest: The sauce will seem thin right out of the air fryer. Let the dish rest for 3-5 minutes before serving; this allows the sauce to cool and thicken perfectly.

FAQ

Q: Can I use pre-shredded cheese for this recipe
A: For the best results, it’s recommended to grate your own cheese from a block. Pre-shredded cheese contains anti-caking agents that can prevent it from melting smoothly, resulting in a less gooey and creamy texture.

Q: Why is my cauliflower bake watery
A: A watery sauce is often caused by excess moisture from the cauliflower. To prevent this, make sure to pat the cauliflower florets completely dry with a paper towel after washing them and before adding them to the pan.

Q: What should I do if the cheese on top browns too quickly
A: Air fryers cook intensely from the top. If you notice the cheese getting too dark before the cauliflower is tender, you can loosely cover the baking pan with a piece of aluminum foil for the remainder of the cooking time.
