An air fryer cooks by rapidly circulating hot air around food, producing a roasted, crispy exterior in less time than an oven and with far less oil than deep frying.

Ingredients for Broccoli & Cauliflower Air Fryer Recipe

Fresh broccoli – crowns or pre‑chopped florets

Fresh cauliflower – whole head or pre‑chopped florets

Butter – butter, ghee, or a dairy‑free alternative

Garlic – fresh minced garlic or garlic powder

Chili flakes – for a touch of heat

Paprika – sweet or smoked, to taste

Salt – to season

Parmesan cheese – freshly grated or shaved, reserve a tablespoon for garnish

How to make air fryer broccoli and cauliflower

Step 1

Wash and cut the broccoli and cauliflower into bite‑sized, uniform pieces. Smaller, evenly sized florets ensure the vegetables cook through without burning on the outside. Place the florets in the air fryer basket in a single layer; work in batches if needed.

Step 2

Mince the garlic finely. Add the garlic and small chunks of butter to the florets. Season with salt, chili flakes, and paprika, and sprinkle most of the Parmesan over the vegetables, saving about a tablespoon for garnish. Toss gently to coat all pieces evenly.

Step 3

Air fry at 360°F (about 180°C) for approximately 20 minutes, shaking or tossing the basket every 5 minutes so the florets brown evenly. Cooking time may vary by air fryer model and the size of your pieces, so check periodically. When done, sprinkle the reserved Parmesan over top and serve immediately.

How to select the best broccoli and cauliflower for air frying

Choose broccoli with firm stems, crisp leaves, and tight, dark‑green florets. Select cauliflower heads that are firm and compact, pale and free of dark spots. Avoid any heads that feel soft or show discoloration.

How to prepare broccoli and cauliflower for air frying

Trim about an inch off the broccoli stem. Don’t discard the stalk—peel away the tougher outer layer with a paring knife and slice the tender inner stalk into bite‑sized pieces. Remove leaves and cut florets into uniform pieces.

For cauliflower, remove leaves and quarter the head. Remove the core from each quarter and break into florets with your hands or a knife, cutting into similar‑sized pieces.

Rinse the prepared vegetables in a colander or soak briefly to remove debris, then pat dry with a clean towel or paper towels to minimize excess moisture. Only wash produce just before using, since broccoli and cauliflower can develop mold if stored wet.

Tip: A simple rinse solution of three parts water to one part vinegar helps clean produce—soak for about five minutes, then rinse and dry.

Pro tips for air frying cauliflower and broccoli

Keep florets uniform in size for even cooking. Arrange vegetables in a single layer and toss the basket every 5–6 minutes. Monitor closely toward the end of cooking to prevent burning.

How long to air fry broccoli and cauliflower

Plan on about 20 minutes at 360°F, shaking the basket every 5 minutes so all sides brown evenly. Adjust time based on your air fryer and the size of the florets.

What to serve with air‑fried cauliflower & broccoli

• Marinated grilled chicken
• Keto bunless hamburger
• Steak
• Salmon fillets
• Seasoned pork chops
• Scrambled eggs
• Use as a filling for lettuce wraps to make it a main dish

Variations to air‑fried cauliflower & broccoli

• Swap chili flakes for black pepper, cayenne, or ground red pepper. Drizzle Sriracha at serving if you prefer.
• Try sweet or smoked paprika for different flavor profiles.
• Add freshly squeezed lemon juice or lemon zest before serving for brightness.
• Garnish with chopped parsley or a pinch of onion powder.
• For dairy‑free options, replace butter with avocado oil, olive oil, coconut oil, or ghee.

How to store leftovers

Refrigerate leftovers in an airtight container, resealable bag, or wrapped tightly in foil for 3–5 days.

To freeze, arrange a single layer of cooled florets on a parchment‑lined baking sheet and flash‑freeze for 1–2 hours. Transfer the frozen pieces to a freezer‑safe container or bag. Freezing them individually prevents clumping and makes reheating easier.

How to reheat roasted broccoli and cauliflower

Reheat in the air fryer for 2–3 minutes at a similar temperature, shaking halfway through to restore crispness. Avoid reheating in the microwave, which makes the vegetables soggy.
