Ingredients You’ll Need

A handful of simple ingredients will give you intensely crunchy, savory Brussels sprouts chips: fresh Brussels sprouts, a light coating of olive oil, garlic (powder or very finely minced), grated Parmesan, and coarse salt and freshly cracked black pepper. Gather these components to highlight texture, aroma, and the nutritional benefits of sprouts. Use the table below to visualize amounts and optional add-ins for creative flavor variations.
| Ingredient | Amount | Notes |
|---|---|---|
| Brussels sprouts | 1 lb | thinly sliced |
| Olive oil | 1–2 tbsp | light coating |
| Garlic | 1 tsp | powder or minced |
| Parmesan & salt | 1/3 cup + pinch | adds umami |
Measure precisely and taste as you go. Adjust quantities to suit your palate, experiment with citrus zest, smoked paprika, or chili flakes to push boundary while keeping balance.
Step-by-Step Air Fryer Method

When the air fryer’s preheated to 375°F (190°C), toss the thinly sliced sprouts with the olive oil, garlic, Parmesan, salt, and pepper until every piece has a light, even coating; you want them dry to the touch but glossy, not soggy.
Arrange in a single layer in the basket, leaving space for hot air circulation. Set timer for 8 minutes, shake basket halfway to promote crisping.
Use high-heat cooking techniques: brief bursts at 400°F for a final 1–2 minutes if you want extra blistering. Watch closely to avoid burning.
Taste a chip for balance, then adjust next batch by tweaking oil, garlic, or cheese for targeted flavor enhancement.
Cool slightly to firm texture before serving; they’ll snap when ready and release garlicky aroma immediately.
Serving Suggestions and Pairings
If you want to highlight their crisp, nutty, garlicky bite, serve the chips straight from the fryer so they snap and release aroma.
Arrange in a shallow bowl to show edges; sprinkle extra grated Parmesan and a squeeze of lemon to brighten. Offer inventive dipping sauces such as smoked paprika aioli, miso-yogurt with chives, or a honey-mustard vinaigrette to contrast salt and umami.
For beverage pairings, choose drinks that cut fat and echo flavors: dry sparkling wine, a bright saison beer, or a citrus-forward gin and tonic. You can also present a green tea infusion for a savory balance.
Plate cleanly, label sauces, and encourage guests to combine chips with different dips and sips to discover bold matches, audibly noting texture shifts between bites.
Storage and Reheating Tips
Since you’ll want to preserve that fresh snap and garlicky aroma for later, cool the chips completely on a wire rack so steam escapes and they don’t go soggy.
Once cooled, layer them in a single layer or separated by parchment in airtight storage containers; chilled, they’ll keep crisp for 2–3 days.
For longer storage, freeze flat on a tray, then transfer to a sealed container for up to a month.
When you’re ready, choose reheating methods that restore crunch: preheat the air fryer to 350°F and re-crisp for 2–4 minutes, or use a hot oven on a tray for 5–7 minutes.
Avoid microwaving; it makes them limp.
Finish with a quick sprinkle of grated Parmesan and a zest of lemon to revive aroma.
Conclusion
You’ll love how these air fryer garlic Parmesan Brussels sprouts chips crisp to golden edges and smell garlicky and nutty. When you pull them hot, let them rest a minute so the surface firms; this keeps crunch intact. Taste for seasoning, adding a pinch more salt or a squeeze of lemon to brighten umami. Serve immediately with your favorite dip and enjoy the contrast of buttery Parmesan, caramelized sweetness, and crunchy texture in every bite.
