Creating Crispy Longhorn Brussels Sprouts is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 425°F (220°C).
2. Prepare Sprouts: Trim the ends of the Brussels sprouts and cut them in half.
3. Prepare Mixture: In a large bowl, combine olive oil, garlic powder, onion powder, paprika, salt, and pepper.
4. Toss Sprouts: Add the halved Brussels sprouts to the bowl and toss them until evenly coated with the oil and spice mixture.
5. Arrange on Tray: Spread the sprouts in a single layer on a baking sheet, cut side down. Make sure they are not overcrowded for maximum crispiness.
6. Roast: Place the baking sheet in the preheated oven and roast for 20-25 minutes until golden brown and crispy. Shake the pan halfway through for even cooking.
7. Add Toppings (Optional): If desired, sprinkle grated Parmesan cheese or chili flakes over the sprouts in the last 5 minutes of roasting for added flavor.
8. Serve: Remove from the oven and serve immediately while hot and crispy.

These steps will ensure you achieve the perfect balance of crispy outer layers and tender interiors, making every bite irresistible.
