Getting a vegetable on the table that the whole family actually eats shouldn’t require an hour of work. These air fryer honey mustard Brussels sprouts come together in about twenty minutes, and the air fryer does most of the heavy lifting while you sort out the rest of dinner. I’ve been making this for over 4 years, and it never disappoints.

Why You’ll Love This Air Fryer Honey Mustard Brussels Sprouts

• One basket, one bowl, done. The sprouts cook in the air fryer while the honey mustard glaze takes thirty seconds to stir together in the same bowl you tossed them in.
• Genuinely fast on a weeknight. No oven preheating, no thirty-minute roast, no hovering. You can walk away and set the table.
• The glaze clings instead of pooling. Because the sprouts go in dry-ish and get tossed in the honey mustard after crisping, the coating stays where it belongs rather than burning on the base of the basket.
• Make-ahead friendly. You can trim and halve the sprouts up to three days ahead and keep the glaze mixed in a jar in the fridge, which turns this into a five-minute assembly job.
• Flexible. The same glaze works on cauliflower florets, broccoli, carrots or a mix, so you can use whatever is wilting in the vegetable drawer.

Ingredients You’ll Need

• 700 g Brussels sprouts, trimmed and halved lengthways
• 2 tbsp olive oil
• ½ tsp fine sea salt
• ¼ tsp freshly ground black pepper
• 3 tbsp runny honey
• 2 tbsp Dijon mustard
• 1 tbsp wholegrain mustard
• 1 tbsp apple cider vinegar
• 1 tsp lemon juice
• 1 small garlic clove, finely grated
• ¼ tsp smoked paprika
• 1 tbsp chicken stock (or vegetable stock), optional, for loosening
• 1 tbsp toasted sesame seeds, to finish
• 1 spring onion, thinly sliced, to finish
• Pinch of chilli flakes, optional

Tip: Buy sprouts that are all roughly the same size — about the diameter of a two-pound coin. If your bag has a few giants mixed in, quarter those so everything finishes cooking at the same moment. Uneven sizes are the single most common reason people end up with charred outsides and raw middles.

How to Make Air Fryer Honey Mustard Brussels Sprouts

1. Trim and halve. Cut the dry base off each sprout, then halve it lengthways through the core. The core is what holds the leaves together — if you slice it off completely, you’ll end up with loose leaves that blow around the basket and scorch. Pull away any outer leaves that look yellowed or limp.
2. Dry them properly. Tip the halved sprouts into a clean tea towel and pat them dry, then leave them for two minutes. They should feel matte, not slick. Wet surfaces steam rather than crisp, and steam is the enemy of browning.
3. Toss with oil and seasoning. In a large mixing bowl, combine the sprouts, olive oil, salt and pepper. Use your hands and get into the layers so the oil reaches between the leaves, not just the outside. They should look glossy but not dripping.
4. Air fry in a single layer. Tip into the air fryer basket and shake into one even layer, cut sides facing up where you can manage it. Cook at 190°C for 12–14 minutes, shaking the basket firmly at the halfway mark. You’re listening for a light rustle as they tumble, and looking for deep golden edges with a few dark, crisp outer leaves.
5. Check for doneness. At the 12-minute mark, spear the thickest piece with a knife. It should slide in with almost no resistance, and the outside should be blistered and caramelised at the edges. If the centres still feel firm, give them another 2–3 minutes.
6. Mix the glaze while they cook. In a small bowl, whisk the honey, both mustards, vinegar, lemon juice, grated garlic and smoked paprika until smooth and glossy. It should ribbon off the whisk. Add the stock a teaspoon at a time if it feels too thick to coat.
7. Toss immediately. Tip the hot sprouts straight into the glaze bowl and toss with a wooden spoon. Do this the second they come out of the basket — hot sprouts absorb the glaze, cold ones just wear it. The smell at this point is sharp mustard, sweet honey and toasted garlic all at once.
8. Finish and serve. Scatter over the sesame seeds, spring onion and chilli flakes if using, then taste one. Adjust with a pinch more salt or a squeeze of lemon, and get them to the table while the edges are still crisp.

Tips From My Kitchen

• Don’t crowd the basket. If your air fryer is on the smaller side, cook the sprouts in two batches. Piled-up sprouts trap moisture between each other and come out soft and grey rather than crisp and browned. It adds five minutes but changes the whole result.
• Keep the glaze off during cooking. Honey burns quickly at air fryer temperatures. Adding it before cooking gives you blackened, bitter edges and a sticky basket. Glaze after, always.
• Halve, don’t shred. Shaved sprouts sound appealing but the loose leaves fly up into the heating element and scorch. Halves give you a crisp exterior and a tender middle, which is what you actually want.
• Prep ahead for the week. Trim and halve a double batch on Sunday, dry them thoroughly, and store in a lidded container lined with kitchen paper. They’ll keep for three days. Mix the glaze in a jar at the same time and it’ll hold for a week — just give it a stir before using.
• Reheat gently, not aggressively. Leftovers go back in the air fryer at 160°C for 4 minutes. Higher than that and the honey in the glaze catches and turns bitter. They won’t be quite as crisp as fresh, but they’re still very good.
• Taste the glaze before it hits the sprouts. Honey varies wildly in sweetness and Dijon varies in heat. Dip a finger in and adjust — more lemon if it’s cloying, more mustard if it’s flat. This takes ten seconds and saves a whole batch.
• Save the loose leaves. The ones that fall off during trimming make excellent crispy bits. Toss them in with the rest, but check the basket at the 8-minute mark because they’ll be done first.

Equipment You’ll Need

• Large frying pan or skillet
• Sharp knife and cutting board
• Mixing bowls
• Wooden spoon or spatula

What to Serve With Air Fryer Honey Mustard Brussels Sprouts

• Roast chicken thighs or a simple grilled chicken breast
• Pan-seared salmon fillets with lemon
• Warm flatbreads and a bowl of hummus for a lighter dinner
• Buttered noodles or plain rice to soak up the extra glaze
• A crisp green salad with a sharp vinaigrette to balance the sweetness

If you’re building out a fuller weeknight menu, our butter steak recipe pairs beautifully with these sprouts, and the ground beef and rice skillet is another one-pan option that keeps cleanup to a minimum. For anyone cooking with halal ingredients in mind, both work exactly as written. And if you’d like a slower, oven-based version of this vegetable, my roasted Brussels sprouts recipe is worth a look.

Notes

Dry the sprouts thoroughly before oiling — wet surfaces steam instead of crisping. Keep the cores intact so the leaves hold together in the air fryer. Toss the sprouts in the glaze the moment they leave the basket so they absorb it. Add stock a teaspoon at a time if the glaze is too thick to coat.

I’d love to know how these turn out in your kitchen — whether you went heavier on the Dijon, added a little chilli heat, or swapped in cauliflower because that’s what was in the fridge. My husband, who’s usually picky about anything green, asked for seconds the first time I made these, so I have a feeling they’ll win over your table too. Leave a comment below and tell me what you served them with.
