Honey-Mustard Air Fryer Brussels Sprouts

Honey-Mustard Air Fryer Brussels Sprouts ; If you love crispy Brussels sprouts with a sweet-tangy finish, this recipe will be your new weeknight side. I’ve tested this twice in both a Ninja and a Cosori air fryer, and the best texture hit at 380°F (193°C) with a quick shake midway and a final glaze to caramelize. You’ll get crackly leaves, tender centers, and that signature honey-Dijon gloss—without heating the whole kitchen.

Ingredients

• 1 ½ lbs Brussels sprouts (680 g), trimmed and halved (quarter extra-large)
• 2 tbsp olive oil (30 ml)
• ¾ tsp kosher salt, plus more to taste
• ½ tsp black pepper
• 1 tbsp lemon juice (15 ml)
• 2 tbsp honey (30 ml) (see swaps for vegan option)

Swaps & Notes (dairy-free, gluten-free, no alcohol/pork)

Tip: For even cooking, aim for similar sprout sizes. Quarter any that are over 1.5 inches wide.

Step-by-Step Instructions

• Prep the sprouts: Trim stem ends, remove ragged outer leaves, and halve (quarter larger ones). Pat very dry.

• Season: In a large bowl, toss sprouts with olive oil, salt, and pepper until glossy.

• Air fry (first cook): Add to basket in a mostly single layer (a little overlap is fine). Cook at 380°F (193°C) for 8 minutes, then shake or stir.

• Make the glaze: Whisk honey, Dijon, lemon juice, garlic, and red pepper flakes. Pour half into a small bowl for finishing.

• Glaze & finish: Toss hot sprouts with the remaining glaze, return to air fryer 2–5 minutes more (until charry edges and sticky-caramelized). Toss with reserved glaze and lemon zest; season to taste.

Pro Tips & Variations

• Dry = Crispy: Moisture is the enemy of browning. After rinsing, spread sprouts on a towel for a few minutes before seasoning.
• Don’t overcrowd: If your basket is small, cook in two batches for better airflow.
• Size matters: Smaller halves cook faster; check at 10–11 minutes total. Larger quarters may need 15–16.
• Extra-crispy finish: After the final glaze, bump to 400°F (204°C) for the last 1 minute.
• Savory twist: Add 1 tsp soy or tamari to the glaze for umami (keeps it gluten-free if using tamari).
• Maple-mustard: Make it vegan by swapping in maple syrup; add a tiny pinch of salt to balance.
• Kid-friendly: Skip red pepper flakes; finish with a dusting of grated Parmesan or dairy-free parm.

Serving Suggestions

• Pile alongside roast chicken, grilled salmon, or a veggie-packed grain bowl.
• Add to a warm farro salad with dried cranberries, toasted almonds, and feta (or dairy-free feta).
• Serve with a quick Greek yogurt (or coconut yogurt) dip: yogurt + Dijon + lemon + pinch of salt.

Storage & Reheating

• Fridge: Store in an airtight container 3–4 days.
• Reheat (best): Air fryer 350°F (177°C) for 3–5 minutes until re-crisped.
• Microwave: 45–60 seconds; texture will soften.
• Freeze: Up to 2 months (texture softer after thawing). Reheat in air fryer to revive.

Food safety: Cool to room temp within 2 hours; refrigerate promptly.

Quick Storage Time Table

Troubleshooting

• Charred outside, firm inside: Pieces are too large. Quarter big sprouts, lower temp to 370°F (188°C) and add 2–3 minutes.
• Soggy sprouts: Basket overcrowded or not dried well. Cook in batches and pat dry next time.
• Bitter taste: Overcooked or old sprouts. Pick firm, bright green sprouts; finish with a squeeze of lemon to balance.
• Glaze burned: Add glaze after an initial cook, then finish briefly. Honey burns if applied too early.
