Creating Crispy Brussels Sprouts with Dijon Aioli is straightforward if you follow these simple steps:

1. Preheat the Oven: Set your oven to 425°F (220°C).

2. Prepare Brussels Sprouts: Trim the stems and slice the Brussels sprouts in half. Rinse and pat dry.

3. Toss with Oil and Seasonings: In a large bowl, combine the Brussels sprouts with olive oil, garlic powder, paprika, salt, and pepper. Toss until they are well coated.

4. Spread on Baking Sheet: Arrange the Brussels sprouts in a single layer on a baking sheet lined with parchment paper.

5. Roast in Oven: Place the baking sheet in the preheated oven and roast for 25-30 minutes, or until they are golden brown and crispy, tossing them halfway through for even cooking.

6. Prepare Dijon Aioli: In a small bowl, mix mayonnaise, Dijon mustard, minced garlic, lemon juice, salt, and pepper until smooth and well blended.

7. Serve: Once the Brussels sprouts are done, remove them from the oven. Serve immediately with the Dijon aioli on the side for dipping.
