Longhorn Brussel Sprouts Recipe Air Fryer: Copycat Crispy Parmesan Bites

I’ve perfected this copycat version to deliver the same crispy, golden edges and bold flavor you love from the restaurant—right in your air fryer.

The secret is a simple yet precise seasoning blend and high heat that transforms brussel sprouts into addictive, bite-sized morsels. No deep frying required.

Each piece emerges with a shatteringly crispy exterior and tender center, coated in a savory parmesan crust. It’s the ideal balance of texture and taste.

Ready in under 20 minutes, this dish proves that restaurant-quality results are achievable at home with minimal effort.

Ingredients for Longhorn Brussel Sprouts Recipe Air Fryer

Crispy air-fried Brussels sprouts with bold savory flavor and a cheesy crust.

The Brussels sprouts are everything here. Look for firm, bright green heads—avoid any with yellowing leaves or soft spots. Trader Joe’s or Whole Foods usually have the best selection. Size matters: smaller sprouts cook faster and get crispier, so halve larger ones to match. The nutritional yeast is your parmesan substitute—Bragg or Bob’s Red Mill are reliable brands with that essential umami kick.

No nutritional yeast? Vegan parmesan shreds work in a pinch (check the label for dairy). Smoked paprika can be swapped for regular, but you’ll lose that signature depth. Maple syrup brings balance—agave or date syrup at one-to-one ratio keeps it vegan. If your sprouts aren’t crispy enough, cornstarch is non-negotiable. Skip it, and you’ll miss that shatteringly crisp texture the recipe promises.

Store unwashed sprouts in a perforated bag in the fridge for up to 5 days. Nutritional yeast keeps in a cool, dark place for 6-12 months. Leftovers? Re-crisp in the air fryer for 2-3 minutes—still delicious the next day.

Step-by-Step Instructions for Copycat Crispy Parmesan Bites

Here’s how to recreate that Longhorn magic at home with these crispy, cheesy bites.

Step 1: Prep the Brussels Sprouts for Maximum Crisp

Start by trimming the 1.5 lb Brussels Sprouts, removing any loose outer leaves and cutting them in half. This step is crucial for even cooking and ensures every piece gets that coveted crispy texture.

Toss the halved sprouts in a large bowl with the 2 tbsp Olive Oil, 1 tsp Garlic Powder, 1 tsp Onion Powder, 0.5 tsp Smoked Paprika, 1 tsp Sea Salt, and 0.5 tsp Black Pepper. These seasonings create the smoky, savory base that defines the Longhorn flavor.

Sprinkle the 1 tbsp Cornstarch over the sprouts and toss again to coat evenly. The cornstarch is the secret to achieving that extra crispy exterior, so don’t skip it.

Step 2: Air Fry to Golden Perfection

Preheat your air fryer to 380°F. This high heat is key for getting the sprouts crispy without burning them. Arrange the seasoned Brussels sprouts in a single layer in the air fryer basket, ensuring they don’t overlap.

Air fry for 12-15 minutes, shaking the basket halfway through the cooking time. You’ll know they’re ready when the edges turn deep golden brown and the sprouts are tender when pierced with a fork.

Watch closely during the last few minutes—air fryers can vary, and you want that perfect balance of crispy and tender.

Step 3: Toss in the Signature Cheesy Glaze

While the sprouts are still hot, transfer them to a large bowl. Immediately drizzle with the 1 tbsp Maple Syrup and 1 tbsp Lemon Juice. The heat from the sprouts will help the glaze cling beautifully.

Sprinkle the 0.5 cup Nutritional Yeast over the sprouts and toss gently to coat evenly. This ingredient is the star of the show, delivering that signature cheesy, parmesan-like flavor that makes these bites so addictive.

Let them sit for 2 minutes before serving. This allows the nutritional yeast to melt slightly and adhere to every crispy bite.

Step 4: Serve Immediately While Crispy

These copycat bites are best served fresh out of the air fryer when they’re at their crispiest. The contrast of the crispy exterior with the tender interior and the cheesy, smoky glaze is what makes them irresistible.

If you need to hold them for a few minutes, keep them in the air fryer basket at 200°F to maintain their texture. But trust me, they won’t last long once your guests get a taste of this Longhorn-inspired treat.

Storing and Reheating longhorn brussel sprouts recipe air fryer

Refrigerator Storage

Let your sprouts cool completely before storing in an airtight container. They’ll keep fresh in the fridge for up to 3 days, though the texture is best within 24 hours. I use glass containers to avoid any plastic aftertaste. ❄️

Freezer Storage

Freeze in a single layer on a baking sheet first to prevent sticking, then transfer to a freezer-safe bag. They’ll stay crispy for up to 1 month. Label your bag with the date—trust me, you’ll forget otherwise.

Air Fryer Reheating

Re-crisp leftovers by spreading in a single layer and air frying at 380°F for 3-4 minutes. Shake the basket halfway to ensure even heating. This method restores that shatteringly crisp texture almost perfectly.

Oven Reheating

Preheat your oven to 400°F and spread sprouts on a baking sheet. Reheat for 5-7 minutes, flipping halfway. It’s not as fast as the air fryer but works in a pinch.

Microwave Option

For a quick fix, microwave for 30-45 seconds on a paper towel-lined plate. They’ll soften, but a sprinkle of nutritional yeast after reheating helps revive the flavor. 🔥

Room Temperature Tip

If serving at a party, keep sprouts warm in the air fryer at 200°F for up to 30 minutes. They’ll stay crispy without overcooking—ideal for entertaining.
