Crispy Brussels sprouts, salty bacon, and a glossy balsamic glaze hit that sweet-and-savory balance that works for weeknights and holidays alike. This air fryer version cooks fast, keeps the sprouts tender inside, and finishes with a sticky drizzle that clings to every leaf.
Why This Air Fryer Recipe Works
The air fryer blasts the sprouts with high, dry heat, which helps the cut sides brown quickly while the centers stay creamy. Cooking the bacon separately (or alongside in a smart way) keeps everything crisp instead of greasy.
A quick balsamic reduction gives you big flavor without a long simmer. You’ll add it at the end so it stays shiny and doesn’t burn.
High heat + halved sprouts = more surface area for browning
Bacon adds fat and salt without needing heavy sauces
Glaze finishes the dish with tangy sweetness that balances bitterness
Ingredients You’ll Need
Stick with fresh Brussels sprouts for the best texture. Frozen can work, but you’ll lose some crisp edges and may need extra cook time.
1 lb fresh Brussels sprouts, trimmed and halved (quarter large ones)
4 slices bacon, cooked until crisp and chopped
1 to 1 1/2 tbsp olive oil (use less if your bacon is very fatty)
3/4 tsp kosher salt, plus more to taste
1/4 tsp black pepper
1/2 tsp garlic powder (optional)
Pinch of red pepper flakes (optional)
For the balsamic glaze:
1/2 cup balsamic vinegar
1 1/2 tbsp brown sugar or honey
How to Make Air Fryer Brussels Sprouts with Balsamic Glaze and Bacon in the Air Fryer
1) Make the balsamic glaze.
Add balsamic vinegar and brown sugar (or honey) to a small saucepan. Simmer over medium-low, stirring occasionally, until reduced by about half and syrupy enough to coat a spoon, 6–10 minutes. Set aside to cool (it thickens as it sits).
2) Prep the Brussels sprouts.
Trim the stem ends, remove any loose outer leaves, and halve the sprouts. Dry them well with a towel; moisture is the enemy of browning.
3) Season.
Toss Brussels sprouts with olive oil, salt, pepper, and garlic powder if using. Don’t add the glaze yet.
4) Air fry.
Preheat the air fryer if your model requires it. Add sprouts in a single layer (a little overlap is fine). Air fry, shaking the basket halfway through, until deeply browned on the cut sides and tender inside.
5) Add bacon and glaze.
Transfer sprouts to a bowl. Toss with chopped crispy bacon, then drizzle with balsamic glaze and toss again. Start with a little glaze and add more to taste so the sprouts stay crisp instead of saucy.
Air Fryer Time and Temperature
Use this as a baseline and adjust for your air fryer’s size and how packed the basket is.
Temperature: 380°F
Time: 12–16 minutes total
Shake/toss: at 6–8 minutes
If you like extra char on the edges, bump to 400°F for the last 2 minutes. If your sprouts are very large, expect the full 16 minutes (or quarter them for faster cooking).
Tips for the Best Results
Dry sprouts brown better. After washing, give them a few minutes on a towel, then pat dry.
Cut-side contact matters: place as many halves cut-side down as you reasonably can.
Don’t crowd: cook in two batches if needed for crisp edges.
Add glaze after cooking: balsamic can burn in the air fryer and turn bitter.
Salt after tasting: bacon varies a lot in saltiness.
If the sprouts are browning too fast but still firm inside, lower the temp to 360°F and cook 2–4 minutes longer. Different air fryers run hot, especially smaller basket models.
Variations and Substitutions
Keep the same method and swap flavors based on what you have.
Swap bacon: use pancetta, diced ham, or turkey bacon (cook until crisp first).
Cheesy finish: add a sprinkle of shaved Parmesan after glazing.
Maple version: replace brown sugar with maple syrup in the glaze.
No refined sugar: use honey and reduce a little longer for a thicker glaze.
Extra tang: finish with a tiny squeeze of lemon right before serving.
What to Serve With It
These Brussels sprouts work as a side for chicken, pork, steak, or salmon. The sweet-tangy glaze also plays well with simple mains that aren’t heavily sauced.

Pork chops with a simple pan sauce
Holiday-style plates with stuffing and mashed potatoes
A grain bowl with quinoa, roasted sweet potato, and a soft-boiled egg
How do I make Brussels sprouts crispy in the air fryer?
Dry them well, toss with a light coat of oil, and avoid crowding the basket. Halving creates more flat surface area to brown, and shaking halfway through helps even crisping.
Can I cook the bacon in the air fryer too?
Yes. Air fry bacon slices at 380°F for about 7–10 minutes (depending on thickness), then chop and set aside. Cook the sprouts afterward so they don’t steam in bacon splatter, and toss bacon in at the end.
Can I use frozen Brussels sprouts?
You can, but they won’t get quite as crisp because they release more moisture. Air fry straight from frozen at 380°F for 16–20 minutes, shaking often, and expect softer edges.
Why is my balsamic glaze bitter?
Balsamic can turn bitter if it’s reduced too aggressively or cooked until very dark. Simmer gently and stop when it coats a spoon; it will thicken more as it cools.
Do I need to preheat my air fryer?
Some models benefit from a 3–5 minute preheat for better browning, especially with vegetables. If your air fryer heats quickly or you’re cooking small batches, you can usually skip it and just add 1–2 minutes to the total time as needed.
