Ingredients You'll Need

• Brussel sprouts- fresh ones work best.
• Salt- just a pinch for the brussels.
• Oil- for frying.
• Butter- unsalted butter.
• Chili rub- or Calabrian chili powder.
• Sea salt- for the sauce.
• Honey- for the delicious coating on the sprouts.
• Sugar- for more sweetness.

How To Make Longhorn Brussel Sprouts

Step 1: Prep The Brussel Sprouts

Before you get started, give the brussel sprouts a good wash and set them aside. Then, get the water boiling. Fill a saucepan with water and make sure to salt it generously. Additionally, to speed up the boiling process, cover the pot with a lid to trap the heat.

Step 2: Blanch The Brussel Sprouts

Put the sprouts in the water and blanch them for 4 minutes. Blanching the vegetables in boiling water will help retain as much of their nutritional value as possible. Also, the brussel sprouts don't need to be fully cooked at this stage, so don't worry if they still seem a little underdone. Once blanched, drain them well and set aside while you prepare the seasoning.

Step 3: Make The Seasoning

It's time to get some flavor going! In a small bowl, combine the chili rub, sea salt, honey, and sugar to form a well-blended paste, and set it aside for later use.

Step 4: Fry and Season The Sprouts

To cook the brussels, the first thing you'll want to do is coat a frying pan in a thin layer of oil and bring it to medium-high heat. Once hot, flash-fry the Brussels sprouts until they're golden and crispy. This will only take a few minutes. As soon as they're nice and crispy, you can drain off any excess oil and transfer the Brussels sprouts to a large bowl.

Now it's time to make the sauce. Melt the butter in the microwave and pour it into the bowl of seasoning. Mix to combine, then pour it over the sprouts and give them a good toss to coat them evenly before serving. 

Expert Tips

• Clean your sprouts well: Rinse the Brussels sprouts thoroughly and trim the ends to remove any dirt or tough outer leaves before cooking.
• Toss them while cooking: Stir or shake the pan a few times while the sprouts roast or sauté to ensure even browning and crispiness on all sides.
• Coat with the chili butter blend immediately: Transfer the hot, crispy sprouts straight into the bowl with the melted butter and chili seasoning. Toss thoroughly so every sprout gets evenly coated.
• Finish with Parmesan for extra flavor: Sprinkle freshly grated Parmesan cheese over the Brussels sprouts just before serving for a savory, restaurant-style finish.
• Use the air fryer for extra crispiness: If you're using an air fryer, cook the Brussels at 375°F for 12–15 minutes, shaking halfway through. It gives them a perfect crispy edge without deep frying.
• Don’t overcrowd the pan or air fryer: Give the Brussels space to breathe—if they’re too close together, they’ll steam instead of crisp.
• Roasting in the oven? Use high heat: Set your oven to 425°F and roast the Brussels for 20–25 minutes, flipping once. The high temperature helps develop that deep, caramelized flavor.

FAQS About This Longhorn Brussel Sprouts Recipe

What makes LongHorn Brussels sprouts so crispy?

The key is high heat and proper spacing. Whether you’re roasting or air-frying, ensure the sprouts aren’t crowded and are cut-side down for maximum caramelization. A quick toss in a seasoned butter blend after cooking adds flavor and gloss.

Can I make these in the air fryer?

Yes! Air fry at 375°F for 12–15 minutes, shaking halfway through. This method makes the sprouts extra crispy with less oil and faster cooking time.

What’s in the LongHorn Brussels sprouts sauce?

The signature flavor comes from a buttery chili seasoning blend, often including red pepper flakes, garlic, and a touch of sweetness. This recipe recreates that bold, slightly spicy finish with pantry-friendly ingredients.

Can I use frozen Brussels sprouts?

Fresh sprouts work best for crispiness, but you can use frozen in a pinch. Thaw and pat them dry thoroughly before cooking, and expect a softer texture.

How do I store and reheat leftovers?

Store leftover Brussels sprouts in an airtight container in the fridge for up to 3 days. Reheat in the air fryer or oven at 375°F for 5–7 minutes to bring back the crispiness. Avoid microwaving—they’ll get soggy.
