Trim the tip ends of the Brussels sprouts and slice them in half. For extra-large sprouts, quarter them. For super tiny ones, leave them in whole.
Rinse and soak them in a large bowl of room temperature water for 10 minutes to help make the centers more tender. After soaking, drain and pat them dry with a clean kitchen towel.
Transfer the sprouts to a large mixing bowl and toss with salt and olive oil.
Oven Method:
Spread the Brussels sprouts, cut-side down, in a single layer on a sheet pan. This helps the cut side brown more quickly.
Bake at 400°F (204°C) in a convection oven or 425°F (218°C) in a conventional oven for 25 to 30 minutes. Check after 25 minutes. The sprouts should be golden brown and crispy.
Air Fryer Method:
Spread the Brussels sprouts in a single layer, with small overlaps being okay. Air fry at 400°F (204°C) for 5 minutes. Shake the basket, then air fry for another 3-4 minutes. The sprouts should be crisp outside once cooked.
Sauce:
Meanwhile, prepare the sauce. In a measuring cup, combine the ingredients from sriracha to salt and stir well.
To emulsify the sauce, hold the whisk in one hand and slowly pour in the oil with the other hand while whisking continuously.
In a saucepan, melt 1 tbsp of butter over low heat, then add 4 tbsp of the honey sriracha sauce. Stir to combine for 1 minute and then turn off the heat.
Combine:
While the sprouts are hot from the oven or air fryer, transfer them to a large mixing bowl and pour over the honey sriracha sauce with butter. Toss well.
Transfer to a large serving plate and serve hot.
Notes
Soaking: Soaking Brussels sprouts makes the centers more tender and helps them cook evenly, ensuring a perfect balance of crispy outside and tender inside.
Pat Dry: After soaking, make sure to pat the sprouts dry so they can crisp up properly.
Why Use Butter: Adding a touch of melted butter to the honey sriracha sauce instantly boosts flavor, making the sprouts taste as rich as restaurant-quality dishes.
Don’t Overpack: Whether using an air fryer or oven, don’t overcrowd the basket or sheet pan—overpacking can cause the sprouts to turn soggy instead of crispy.
Storage: Store leftovers in the fridge for up to 4 days. To reheat and crisp up, air fry at 380°F (193°C) for 4 minutes or reheat on a stovetop until warmed through.
