Air Fryer Parmesan Roasted Cauliflower is a wonderfully crispy and flavorful veggie snack or side dish. The cauliflower gets perfectly roasted in the air fryer, with a golden, crunchy coating of Parmesan cheese that adds a cheesy punch to every bite. It’s light, tasty, and easy to whip up when you want something a little special without a lot of fuss.
I love making this when I want a quick side that feels a bit fancy but is actually super simple. The air fryer crisps everything up so nicely, and the Parmesan adds just the right amount of saltiness and richness without needing extra oil or heavy sauces. I usually toss the cauliflower with a bit of garlic powder and pepper before popping it in the air fryer—that’s my go-to flavor boost.
This dish is great served alongside grilled chicken or as a snack on its own with a squeeze of lemon for a little zing. It’s one of those things you can keep coming back to because it’s both healthy and satisfying. Plus, it’s a sneaky way to get more veggies on the table since everyone loves the crispy, cheesy crunch!
Key Ingredients & Substitutions
Cauliflower: Fresh cauliflower works best here for that perfect crispness. Try to pick firm, white heads without dark spots. If you can’t find fresh, frozen florets can work—just thaw and pat dry well before cooking.
Parmesan Cheese: This gives the dish its cheesy crunch. You can swap with Pecorino Romano for a sharper taste or nutritional yeast for a dairy-free, vegan option.
Olive Oil: Olive oil helps the cauliflower roast evenly and crisp up. Avocado oil or melted coconut oil are great alternatives if you need a different flavor or higher smoke point.
Garlic Powder & Paprika: These spices add warmth and a little kick. Smoked paprika gives a deeper smoky flavor, but feel free to skip or swap with chili powder for heat.
How Do I Get the Cauliflower Crispy in the Air Fryer?
Getting that crispy outside with tender inside is all about space, oil, and timing.
- Cut the florets evenly, about 1-2 inches, so they cook uniformly.
- Toss them with enough oil to coat but not soak—this helps the cheese stick and crisps the surface.
- Don’t overcrowd the air fryer basket. Give each piece room to let hot air circulate for crispiness.
- Shake or stir halfway through cooking to avoid burning and to brown all sides evenly.
- Watch closely near the end—once edges are golden brown, it’s done!
Equipment You’ll Need
- Air fryer – I love it because it makes cauliflower crispy without extra oil and is quick to heat up.
- Mixing bowl – for tossing the cauliflower evenly with oil and seasonings.
- Measuring spoons and cups – to keep the seasonings just right.
- Spatula or tongs – to transfer and toss the cauliflower safely and easily.
Flavor Variations & Add-Ins
- Spice it up with chili powder or cayenne pepper for some heat; perfect if you like a little kick.
- Use Italian herbs or Italian seasoning instead of paprika for a herby flavor.
- Add a squeeze of lemon or a splash of balsamic vinegar after cooking for extra brightness.
- For more cheesiness, sprinkle shredded mozzarella or cheddar on top just before serving.

How Much Time Will You Need?
This recipe takes about 5 minutes to prep and about 12-15 minutes to cook in the air fryer. So, in under 20 minutes, you’ll have a delicious and crispy Parmesan roasted cauliflower ready to serve!
Step-by-Step Instructions:
1. Preheat and Prepare:
Start by preheating your air fryer to 400°F (200°C). While it heats up, wash and cut your cauliflower into bite-sized florets.
2. Season the Cauliflower:
In a large bowl, toss the cauliflower florets with olive oil, making sure every piece gets a nice coating. Next, sprinkle in the Parmesan cheese, garlic powder, paprika if you’re using it, and season with salt and black pepper. Mix everything well so the cauliflower is evenly coated with the flavors.
3. Air Fry:
Place the cauliflower in a single layer inside your air fryer basket. Don’t overcrowd the basket to help the florets crisp up nicely. Cook for 12 to 15 minutes, shaking the basket gently halfway through to ensure even roasting. Look for golden brown, crispy edges as your cue that it’s done.
4. Serve and Enjoy:
Once cooked, transfer the cauliflower to a plate. If you like, sprinkle some fresh chopped parsley on top. Serve immediately with lemon wedges on the side – a little squeeze of lemon juice brightens up the cheesy, roasted flavors perfectly. Enjoy!
Can I Use Frozen Cauliflower Florets?
Yes, you can use frozen cauliflower, but be sure to thaw them completely and pat dry to remove excess moisture. This helps achieve a crispy texture in the air fryer.
How Should I Store Leftovers?
Store any leftover cauliflower in an airtight container in the refrigerator for up to 3 days. Reheat in the air fryer or oven to regain crispiness.
Can I Substitute Parmesan Cheese?
Absolutely! You can use Pecorino Romano for a sharper flavor or nutritional yeast if you want a dairy-free option, though the texture and taste will vary slightly.
What Should I Serve with This Dish?
This crispy Parmesan cauliflower pairs well with grilled chicken, fish, or as a tasty snack. Adding a squeeze of lemon juice right before serving enhances the flavor beautifully.
