Air Fryer Brussels Sprouts with Bacon (Crispy + Maple Glaze)

There is a particular kind of holiday stress that only the Thanksgiving cook fully understands: the turkey needs the oven for four hours, the casserole needs it for forty-five minutes, the rolls need a blast of heat right before dinner, and somewhere in there you are supposed to get vegetables on the table too. This is where the air fryer earns its keep. These air fryer Brussels sprouts with bacon cook to a deep, crackly caramelization in about twenty minutes, entirely outside the oven, while the big dishes do their thing. They arrive at the table shattering-crisp at the edges, tender in the middle, and glistening with a maple-Dijon glaze that turns even the committed sprout skeptics into converts.

The reason this recipe works so well is the air fryer's superpower: fast, circulating heat that wicks moisture off the surface of the sprouts almost as quickly as it builds it up. A Brussels sprout is essentially a tiny cabbage, and cabbage loves to steam — which is exactly why oven-roasted sprouts sometimes turn out soft and soggy. Halving the sprouts and setting them cut-side down in the air fryer basket exposes the flat face to direct, concentrated heat, and that is where the magic happens. The natural sugars caramelize, the outer leaves crisp like chips, and the centers cook through to a sweet, creamy bite. No flipping army of sheet pans, no parboiling, no complicated prep.

Then comes the bacon. Chopping the bacon into small pieces and scattering it over the sprouts means the fat renders directly onto the vegetables as they cook, basting them in smoky pork fat while the bacon itself crisps to little chewy-crunchy nuggets. The finishing move is a glaze of pure maple syrup whisked with Dijon mustard — just enough to lacquer the sprouts without drowning them. The maple brings a warm, woodsy sweetness, the Dijon brings a sharp tang that keeps the whole dish from tasting one-note, and a pinch of red pepper flakes adds a background warmth. Smoky, sweet, tangy, crisp, and ready in about thirty-five minutes start to finish, this is the side dish that lets your oven breathe on the biggest cooking day of the year.

Ingredients

For the sprouts and bacon

• 1 1/2 pounds (about 680 g) fresh Brussels sprouts
• 4 slices (about 4 ounces / 115 g) thick-cut bacon, cut into 1/2-inch pieces
• 2 tablespoons olive oil
• 1 teaspoon kosher salt
• 1/2 teaspoon freshly ground black pepper
• 1/2 teaspoon garlic powder

For the maple-Dijon glaze

• 3 tablespoons pure maple syrup
• 1 tablespoon Dijon mustard
• 1/4 teaspoon red pepper flakes (optional, adjust to taste)
• Flaky sea salt, for finishing (optional)

Why these ingredients matter

Fresh Brussels sprouts, all roughly the same size. Even cooking depends on even sizing, so pick sprouts that are about 1 to 1 1/2 inches across. Oversized ones can be quartered; tiny ones can go in whole. Look for tight, bright-green heads with no yellowing — loose outer leaves crisp beautifully, but yellowing leaves taste bitter and should be trimmed away.

Thick-cut bacon. Thinner bacon crisps too fast and can scorch before the sprouts are done, while thick-cut bacon renders at roughly the same pace as the sprouts caramelize. Chopping it into small pieces maximizes the crispy surface area and lets the fat distribute evenly over every sprout.

Olive oil. The oil is insurance: it coats the cut faces so they brown evenly and helps the seasoning stick. You do not need much, because the bacon renders additional fat into the basket — too much oil is actually the enemy of crispness here.

Kosher salt, black pepper, and garlic powder. Seasoning before cooking means the flavor is built into the caramelized crust rather than sitting on top of it. Garlic powder is used instead of fresh garlic because fresh garlic burns at air-fryer temperatures; the powder distributes evenly and toasts into the coating.

Pure maple syrup. This is the backbone of the glaze, and it must be pure — pancake syrup is mostly corn syrup with maple flavoring and will make the glaze taste flat and cloying. The real thing brings complex, woodsy sweetness that pairs naturally with bacon's smoke.

Dijon mustard. Dijon is the glaze's counterweight. Its sharp, winey tang cuts through the maple's sweetness and the bacon's richness, so the finished sprouts taste balanced rather than candy-like. A grainy whole-grain mustard also works if that is what you have.

Red pepper flakes. Optional but recommended — a quarter teaspoon adds a gentle background warmth that makes the sweet-salty-smoky combination taste more dimensional. Increase it to half a teaspoon if your crowd likes heat.

Instructions

1. Prep the sprouts. Rinse the Brussels sprouts and pat them very dry — surface moisture is the number one enemy of crispness. Trim the woody stem end from each sprout and peel away any yellowed or damaged outer leaves. Halve each sprout through the stem end; leave very small sprouts whole and quarter any that are much larger than 1 1/2 inches, so everything is roughly the same size.
2. Season and toss. Place the halved sprouts in a large bowl. Drizzle with the olive oil, then sprinkle over the kosher salt, black pepper, and garlic powder. Toss thoroughly with your hands or a wooden spoon until every piece is evenly coated with oil and seasoning, making sure some oil gets onto the cut faces where the browning will happen.
3. Preheat the air fryer. Set the air fryer to 380 degrees F (193 degrees C) and let it preheat for 3 to 5 minutes. A hot basket jump-starts browning the moment the sprouts go in, instead of letting them sit and steam while the basket warms up.

4. Load the basket. Spread the seasoned sprouts in the air fryer basket in a single layer, cut-side down as much as possible. Scatter the chopped bacon evenly over and around the sprouts. Work in two batches if your air fryer is small — crowding the basket traps steam and produces soft sprouts instead of crisp ones.
5. Air fry the first round. Cook at 380 degrees F (193 degrees C) for 10 minutes. After 10 minutes, shake the basket well to redistribute everything, flipping some of the sprouts onto their other faces. The bacon should be starting to render and the sprouts should be taking on golden edges.

6. Finish cooking. Cook for 8 to 10 minutes more, shaking once halfway through, until the sprouts are deeply golden with charred, crispy outer leaves and tender centers, and the bacon is browned and crisp. A total of 18 to 20 minutes is typical; smaller sprouts may finish a minute or two sooner.
7. Whisk the glaze. While the sprouts finish, whisk the maple syrup, Dijon mustard, and red pepper flakes (if using) in a small bowl until smooth and glossy. Do not glaze the sprouts in the air fryer — the sugars would burn under the high direct heat.

8. Glaze and toss. Transfer the hot sprouts and bacon to a serving bowl and drizzle the maple-Dijon glaze over everything. Toss gently but thoroughly so the glaze lacquers the sprouts without breaking up the crispy leaves. Work while they are still hot so the glaze melts into a thin, even coating.
9. Serve immediately. Sprinkle with a pinch of flaky sea salt if you like, and serve hot. These are at their absolute best in the first 15 to 20 minutes out of the air fryer, when the edges are still crackling.

Variations

• Balsamic finish. Swap the maple-Dijon glaze for a drizzle of good balsamic reduction after cooking. It brings the same sweet-tangy contrast with a deeper, darker caramel note — excellent for Christmas dinner.
• Spicy honey version. Replace the maple syrup with honey and double the red pepper flakes for a hot-honey twist. The glaze gets slightly thicker and glossier, and the heat level is unmistakably bolder.
• Parmesan crust. Skip the glaze and toss the hot sprouts with 1/4 cup of finely grated Parmesan right out of the basket. The cheese melts onto the crispy leaves and adds a salty, umami finish.
• Pancetta swap. Replace the bacon with an equal amount of diced pancetta for a slightly less smoky, more pork-forward flavor. Pancetta renders a little faster, so check the basket a couple of minutes early.
• Bacon-free vegetarian. Omit the bacon and increase the olive oil to 3 tablespoons. The sprouts still caramelize beautifully, and the maple-Dijon glaze carries the dish — finish with toasted pecans for the crunch the bacon would have provided.

Storage

Cooked Brussels sprouts keep in an airtight container in the refrigerator for up to 4 days. The bacon and glaze hold fine, but the sprouts will lose their crisp edges as they sit — that is simply the nature of a fried vegetable. Reheat them in the air fryer at 375 degrees F (190 degrees C) for 4 to 5 minutes, shaking once, to bring back a surprising amount of the original crunch. The microwave will warm them but leaves them soft, so save that for leftovers you are folding into another dish.

For the freezer, spread cooled sprouts in a single layer on a parchment-lined sheet pan and freeze until solid, about 2 hours, then transfer to a freezer bag for up to 2 months. Reheat directly from frozen in the air fryer at 380 degrees F (193 degrees C) for 8 to 10 minutes. The texture will not be quite as crisp as fresh, but the flavor holds up well — they make an excellent quick side on a busy weeknight.

To get ahead for Thanksgiving, halve and season the sprouts up to 1 day before and refrigerate them covered in the bowl; whisk the glaze and store it in a sealed jar at room temperature. On the day, load and air fry in batches as directed, glazing each batch while hot. The whole active cooking window is about 20 minutes per batch, which slots neatly into the time the turkey is resting.
