I used to think Brussels sprouts were the enemy. For years, I avoided them like the plague, remembering those mushy, bitter versions from childhood dinners.
Then one day, I tossed some in my air fryer with a drizzle of balsamic vinegar, and everything changed. The Air Fryer Balsamic Brussels Sprouts Recipe I’m sharing today transformed this once-hated vegetable into something I actually crave.
The outside gets wonderfully crispy while the inside stays tender, and that balsamic glaze adds just the right touch of sweetness to balance the natural earthiness. Now I make these at least twice a week, and even my kids ask for seconds.

Ingredients
Getting the right ingredients makes all the difference in how your Brussels sprouts turn out. I’ve tested this recipe with different types of balsamic vinegar, and quality really matters.
Here’s what you’ll need:
- 1½ pounds (680g) fresh Brussels sprouts: Look for firm, bright green sprouts with tightly packed leaves
- 2 tablespoons (30ml) extra virgin olive oil: The better quality oil you use, the better they’ll taste
- 3 tablespoons (45ml) balsamic vinegar: Aged balsamic works beautifully here
- 2 cloves garlic, minced: Fresh is best for maximum flavor
- 1 teaspoon (5g) honey: Balances the acidity and helps with caramelization
- ½ teaspoon (3g) sea salt: I prefer flaky sea salt for finishing
- ¼ teaspoon (1g) black pepper: Freshly ground makes a difference
- ¼ teaspoon (1g) red pepper flakes (optional): Adds a nice kick if you like heat
- 2 tablespoons (15g) parmesan cheese, freshly grated (optional): For serving

Kitchen Equipment Needed
Having the right tools makes this recipe even easier. The air fryer does most of the work, but a few good quality items help you get the best results.
Essential equipment:
- Air fryer (5-quart or larger capacity): I use mine for almost every meal now
- Sharp chef’s knife: For trimming and halving the Brussels sprouts cleanly
- Cutting board: A stable surface makes prep safer and faster
- Large mixing bowl: For tossing everything together evenly
- Measuring spoons and cups: Accuracy matters for the balsamic glaze
- Kitchen tongs: Perfect for tossing the sprouts halfway through cooking
- Small saucepan: For reducing the balsamic glaze to perfection
Recommended Products for This Recipe
I’ve spent years testing different products for recipes like this, and these are the ones that genuinely make a difference. They’re not just convenient; they actually improve your results.
1. Aged Balsamic Vinegar of Modena
The quality of your balsamic vinegar dramatically affects the final taste. Cheap balsamic can be too sharp and thin, while a good aged variety has natural sweetness and body that coats the Brussels sprouts perfectly. I keep a bottle specifically for recipes like this where balsamic is the star.
2. COSORI Air Fryer 5.8QT
This air fryer changed my cooking life. The large basket means you can cook all the Brussels sprouts in one batch without overcrowding, which is crucial for getting that crispy exterior. The temperature control is precise, and it heats up incredibly fast.
3. Parmigiano Reggiano Cheese Wheel
Real Parmigiano Reggiano transforms this dish from good to extraordinary. The nutty, complex flavor of authentic parmesan melts slightly over the hot Brussels sprouts and adds an umami depth that pre-grated cheese just can’t match. Grate it fresh right before serving.
4. Maldon Sea Salt Flakes
I finish almost every dish with Maldon salt now. The light, flaky crystals add little bursts of saltiness without making the dish too salty overall. Sprinkled on right before serving, it gives these Brussels sprouts a professional restaurant quality.

Step-by-Step Instructions: How to Make Air Fryer Balsamic Brussels Sprouts
I’ve walked dozens of people through this recipe, and these detailed steps ensure perfect results every single time. Even if you’ve never used an air fryer before, you’ll find this surprisingly straightforward.
1. Prepare the Brussels Sprouts
Getting the Brussels sprouts ready properly is half the battle for achieving that perfect texture.
- Rinse the Brussels sprouts under cold water and pat them completely dry with paper towels or a clean kitchen towel (excess moisture prevents crisping)
- Trim off the brown stem ends using a sharp knife, cutting about ¼ inch (6mm) from the bottom
- Remove any yellowed or damaged outer leaves by peeling them away with your fingers
- Cut each Brussels sprout in half lengthwise from top to bottom (this creates flat surfaces that get wonderfully crispy)
- If you have any particularly large sprouts (bigger than a golf ball), cut them into quarters so everything cooks evenly
- Place all the trimmed and halved sprouts into a large mixing bowl
2. Create the Balsamic Marinade
The marinade is where all the flavor magic happens, so take your time mixing this properly.
- In a small bowl, whisk together 2 tablespoons (30ml) of the balsamic vinegar with the olive oil until well combined
- Add the minced garlic, honey, salt, black pepper, and red pepper flakes (if using) to the balsamic mixture
- Whisk everything together vigorously for about 30 seconds until the honey is fully dissolved and the marinade looks emulsified
- Taste the marinade and adjust seasonings if needed (remember, the flavors will concentrate as it cooks)
3. Coat the Brussels Sprouts
Even coating is crucial for getting consistent browning and flavor in every bite.
- Pour the balsamic marinade over the Brussels sprouts in the large mixing bowl
- Using your hands or tongs, toss the sprouts thoroughly for about 1-2 minutes, making sure every piece is evenly coated
- Let the sprouts sit in the marinade for 5 minutes while you preheat the air fryer (this allows them to absorb more flavor)
- Toss them one more time just before cooking
4. Preheat and Load the Air Fryer
Preheating creates that immediate sear that locks in flavor and starts the crisping process.
- Preheat your air fryer to 375°F (190°C) for 3-5 minutes (most models have a preheat function)
- Arrange the marinated Brussels sprouts in the air fryer basket in a single layer with the cut sides facing down (this is important for maximum crispiness)
- Make sure the sprouts aren’t touching too much or overlapping (air circulation is key, so work in batches if necessary)
- If you need to cook in batches, keep the first batch warm in a 200°F (95°C) oven while cooking the rest
5. Air Fry to Perfection
The cooking process requires a little attention, but it’s worth it for those perfectly crispy results.
- Cook the Brussels sprouts at 375°F (190°C) for 8 minutes without opening the air fryer
- After 8 minutes, carefully open the basket and shake it vigorously or use tongs to flip each sprout over
- Continue cooking for another 7-10 minutes, checking at the 7-minute mark (cooking time varies based on sprout size and your specific air fryer model)
- The sprouts are done when the edges are deeply browned and crispy, and a fork easily pierces through the center
- If they need more time, continue cooking in 2-minute increments until you achieve your desired level of crispiness
6. Prepare the Balsamic Glaze
While the Brussels sprouts cook, you’ll make a quick reduction that takes the flavor to the next level.
- Pour the remaining 1 tablespoon (15ml) of balsamic vinegar into a small saucepan
- Bring it to a gentle simmer over medium heat
- Let it reduce for 3-5 minutes, stirring occasionally, until it thickens enough to coat the back of a spoon
- Remove from heat and set aside (it will continue to thicken as it cools)
- If it gets too thick, you can thin it with a few drops of water
7. Finish and Serve
The final touches transform these from good to absolutely incredible.
- Transfer the crispy Brussels sprouts to a serving dish immediately while they’re still hot
- Drizzle the reduced balsamic glaze over the top using a spoon in a back-and-forth motion
- If using, sprinkle the freshly grated parmesan cheese over the hot sprouts (it will melt slightly from the residual heat)
- Add an extra pinch of flaky sea salt and a crack of fresh black pepper if desired
- Serve immediately while they’re at their crispiest and most flavorful

Tips for The Best Air Fryer Balsamic Brussels Sprouts
I’ve made these Brussels sprouts more times than I can count, and these tips come from actual mistakes and discoveries along the way. They’ll help you avoid the pitfalls I encountered and create perfect results every time.
Pro tips from my kitchen:
- Size matters for even cooking: Try to select Brussels sprouts that are roughly the same size, about 1-1.5 inches (2.5-4cm) in diameter
- Don’t skip the drying step: Wet Brussels sprouts will steam instead of crisp, no matter how good your air fryer is
- Cut side down is non-negotiable: Those flat surfaces against the basket create the most delicious caramelization
- Avoid overcrowding at all costs: Air needs to circulate around each sprout; crowding creates soggy vegetables
- Shake or flip halfway through: This ensures even browning on all sides and prevents burning
- Watch them closely near the end: Brussels sprouts can go from perfect to burnt in just 2-3 minutes
- The smaller outer leaves will char: This is actually good; those crispy little bits add incredible flavor and texture
- Fresh is always better: Older Brussels sprouts can taste bitter; choose firm, bright green ones
- Temperature variations exist: Every air fryer is slightly different, so adjust time and temp as needed for your model
- Let them cool slightly before serving: They’ll actually get crispier as they sit for 2-3 minutes
- Taste and adjust: Always taste one before serving and add more salt, pepper, or balsamic if needed

Storage and Reheating
I’m always amazed at how well these Brussels sprouts keep, which makes them perfect for meal prep or making ahead for gatherings. The trick is storing and reheating them properly to maintain that crispy texture.
Storage guidelines:
- Room temperature: Brussels sprouts should not sit out for more than 2 hours after cooking
- Refrigerator storage: Store cooled Brussels sprouts in an airtight container for up to 4 days
- Freezing: While possible, I don’t recommend freezing these as they lose their crispy texture when thawed
- Separate the glaze: If meal prepping, store the balsamic glaze separately and add it just before serving
- Layer with paper towels: Place paper towels between layers of stored Brussels sprouts to absorb excess moisture
Reheating methods:
- Air fryer (best method): Reheat at 350°F (175°C) for 3-5 minutes until crispy and warmed through
- Oven method: Spread on a baking sheet and reheat at 400°F (200°C) for 5-7 minutes
- Stovetop: Heat in a dry skillet over medium-high heat for 3-4 minutes, tossing frequently
- Microwave (not recommended): This makes them soggy, but if you must, use 30-second intervals with a paper towel underneath
- From frozen: If you did freeze them, thaw overnight in the fridge first, then use the air fryer or oven method

Health Benefits of Key Ingredients
Beyond just tasting incredible, this recipe is packed with ingredients that genuinely support your health. I love knowing that something this delicious is also doing good things for my body.
Key health benefits:
- Brussels Sprouts: These tiny powerhouses are loaded with vitamin K for bone health, vitamin C for immune support, and fiber for digestive health. They contain powerful antioxidants called kaempferol and glucosinolates that research suggests may have anti-cancer properties. The high fiber content also helps regulate blood sugar levels and promotes feelings of fullness.
- Balsamic Vinegar: Contains antioxidants called polyphenols that combat cell damage and may improve heart health. The acetic acid in balsamic vinegar can help improve digestion and may assist in blood sugar regulation. It’s also virtually calorie-free while adding tremendous flavor.
- Olive Oil: Rich in heart-healthy monounsaturated fats and anti-inflammatory compounds. Extra virgin olive oil contains oleocanthal, which has anti-inflammatory properties similar to ibuprofen. It may help reduce the risk of heart disease and stroke.
- Garlic: Known for its immune-boosting properties and compounds that may help lower blood pressure and cholesterol. Garlic contains allicin, a sulfur compound that forms when garlic is crushed or chopped, which has powerful medicinal properties.
- Honey: Provides trace amounts of vitamins and minerals, plus antioxidants. Raw honey has antibacterial and anti-inflammatory properties. While it’s still a form of sugar, the small amount used here adds flavor without excessive sweetness.

FAQs About Air Fryer Balsamic Brussels Sprouts
1. How do I prevent my Brussels sprouts from being bitter?
The key to avoiding bitterness is selecting fresh, young Brussels sprouts that are firm and bright green. Older sprouts develop more bitter compounds.
Additionally, the caramelization that happens in the air fryer and the sweetness from the balsamic vinegar and honey work together to balance any natural bitterness. Make sure you’re cooking them until they’re properly browned and crispy, as the Maillard reaction that creates browning also reduces bitterness.
2. Can I use frozen Brussels sprouts instead of fresh?
While fresh Brussels sprouts give the best texture and flavor, you can use frozen in a pinch. The challenge is that frozen sprouts contain more moisture, which makes getting them crispy much harder.
If using frozen, thaw them completely first, then pat them extremely dry with paper towels. You may need to increase the cooking time by 5-7 minutes and shake the basket more frequently.
3. Why are my Brussels sprouts not getting crispy?
The most common culprits are overcrowding the air fryer basket or not drying the sprouts well enough before cooking. Each sprout needs space for hot air to circulate around it.
Also check that you’re placing them cut-side down initially, as this creates maximum contact with the hot basket. Make sure your air fryer is properly preheated to 375°F before adding the sprouts.
4. Can I make these ahead for a dinner party?
Absolutely! You can prep the Brussels sprouts up to the point of cooking several hours ahead.
Trim, halve, and marinate them, then cover and refrigerate until you’re ready to cook. For best results, cook them as close to serving time as possible since they’re crispiest fresh from the air fryer, though they can be reheated successfully using the methods I mentioned in the storage section.
5. What should I do if I don’t have an air fryer?
You can achieve similar results using your oven’s convection setting. Preheat your oven to 425°F (220°C) and arrange the marinated Brussels sprouts on a baking sheet in a single layer, cut-side down.
Roast for 20-25 minutes, flipping halfway through, until they’re browned and crispy. The texture won’t be quite as crispy as air frying, but they’ll still be delicious with that wonderful balsamic flavor.
