Ingredients
For this brunch‑ready delight, the star is fresh Brussels sprouts, trimmed and halved for even cooking. A light coating of olive oil helps achieve that coveted crunch, while garlic, lemon zest, and Parmesan add depth. The glaze combines maple syrup, Dijon mustard, and apple cider vinegar for a sweet‑tangy finish that pairs beautifully with a pinch of spice.
Main Ingredients
- 1 ½ lb Brussels sprouts, trimmed and halved
- 2 Tbsp extra‑virgin olive oil
- 2 cloves garlic, minced
- 1 tsp lemon zest
- ¼ cup freshly grated Parmesan cheese
Sauce/Marinade
- 2 Tbsp pure maple syrup
- 1 Tbsp Dijon mustard
- 1 Tbsp apple cider vinegar
Seasonings & Garnish
- ½ tsp sea salt
- ¼ tsp freshly ground black pepper
- ¼ tsp smoked paprika
- ¼ tsp red‑pepper flakes (optional)
The olive oil creates a thin, even film that encourages browning while keeping the sprouts from drying out. Garlic and lemon zest introduce aromatic brightness that lifts the earthy flavor of Brussels sprouts. The maple‑Dijon glaze supplies a glossy coating that caramelizes during the final minutes of air‑frying, and the Parmesan adds a salty, umami finish. Together, these components produce a dish that’s crisp, flavorful, and nutritionally satisfying.
Step-by-Step Instructions
Preparing the Sprouts
Begin by rinsing the Brussels sprouts under cold water, then pat them completely dry with a clean kitchen towel. Halve each sprout lengthwise to ensure uniform cooking. Transfer to a large bowl, drizzle with olive oil, and toss with minced garlic, lemon zest, salt, pepper, smoked paprika, and red‑pepper flakes. The oil and seasonings should coat every surface for optimal flavor and crispness.
Air Frying the Sprouts
Preheat the air fryer to 375°F (190°C) for about three minutes. Spread the seasoned sprouts in a single layer inside the basket; avoid stacking to allow hot air to circulate. Cook for 12‑15 minutes, shaking the basket halfway through. You’ll know they’re ready when the edges turn golden‑brown and the stems are tender when pierced with a fork.
Tossing in the Maple‑Dijon Glaze
- Make the glaze. In a small saucepan over low heat, whisk together maple syrup, Dijon mustard, and apple cider vinegar. Heat just until the mixture bubbles lightly, then remove from heat.
- Combine with sprouts. Transfer the hot sprouts to a wide mixing bowl. Pour the warm glaze over them and toss gently until every piece is glossy and evenly coated.
- Finish the crunch. Return the glazed sprouts to the air fryer basket and air‑fry for an additional 2‑3 minutes. This short burst caramelizes the glaze, creating a sticky, crisp exterior.
Finishing & Serving
Once the glaze has set, remove the basket and immediately sprinkle the grated Parmesan over the hot sprouts; the residual heat will melt the cheese slightly, adding a savory sheen. Transfer to a serving platter, garnish with an extra pinch of lemon zest if desired, and serve while still warm. Pair with poached eggs, avocado toast, or a light yogurt dip for a complete brunch experience.
Tips & Tricks
Perfecting the Recipe
Dry the sprouts thoroughly. Moisture creates steam, which prevents browning. Pat them completely dry before adding oil and seasonings.
Don’t overcrowd the basket. A single layer ensures hot air circulates, giving each piece a uniform crunch.
Shake halfway. Giving the basket a good shake at the 7‑minute mark flips the sprouts, promoting even caramelization.
Use a light hand with oil. Too much oil can make the glaze soggy; two tablespoons is enough for a crisp finish.
Flavor Enhancements
Add a splash of fresh lemon juice just before serving for a bright pop. Sprinkle toasted pine nuts for extra crunch, or stir in a teaspoon of smoked sea salt for a deeper umami note. A drizzle of hot honey can introduce a subtle heat‑sweet contrast.
Common Mistakes to Avoid
Skipping the final glaze‑caramelization step leaves the sprouts glossy but not sticky, missing that signature crunch. Also, avoid using low‑quality maple syrup; its flavor intensity directly influences the final taste. Finally, don’t over‑cook—the sprouts should stay slightly firm in the center.
Pro Tips
Season while hot. Toss the sprouts with salt and pepper immediately after air‑frying; the heat helps the seasonings adhere.
Use a thermometer. If you’re adding a protein later, a quick read ensures it reaches safe internal temperature without over‑cooking the sprouts.
Batch cooking. For larger groups, cook in two batches and keep the first batch warm in a low oven (200°F) while the second finishes.
Finish with fresh herbs. A sprinkle of chopped parsley or chives adds color and a fresh aromatic lift right before serving.
Variations
Ingredient Swaps
Swap Brussels sprouts for cauliflower florets or sliced sweet potatoes for a different texture. Replace Parmesan with nutritional yeast for a vegan twist, or use almond butter in the glaze for a richer, nutty profile. Even a dash of balsamic reduction can substitute the apple cider vinegar for added depth.
Dietary Adjustments
To keep the dish gluten‑free, ensure the Dijon mustard is certified gluten‑free. For a fully vegan version, replace the Parmesan with vegan cheese or omit it entirely, and use maple syrup as the sole sweetener. Keto diners can halve the maple syrup and add a splash of liquid stevia instead.
Serving Suggestions
Pair these sprouts with poached eggs and a slice of whole‑grain toast for a classic brunch plate. They also shine alongside smoked salmon, avocado ribbons, or a dollop of Greek yogurt mixed with herbs. For a heartier meal, serve over quinoa or cauliflower rice and sprinkle with toasted seeds.
Storage Info
Leftover Storage
Allow the sprouts to cool to room temperature, then transfer them to an airtight container. Refrigerate for up to four days. For longer keeping, portion into freezer‑safe bags, squeeze out excess air, and freeze for up to three months. Thaw in the refrigerator overnight before reheating.
Reheating Instructions
Reheat in a preheated 350°F oven for 10‑12 minutes, uncovered, to restore crispness. If you’re short on time, a quick 2‑minute blast in the air fryer at 375°F works well. Add a drizzle of fresh glaze or a splash of broth if the sprouts look dry.
