Ingredients

For the Crispy Brussel Sprouts:

450 g Brussel sprouts, trimmed and halved
2 tablespoons olive oil
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon paprika
Salt, to taste
Black pepper, to taste

For the Dijon Aioli:

1/2 cup mayonnaise
1 tablespoon Dijon mustard
1 teaspoon lemon juice (fresh if possible)
1 small garlic clove, minced or grated
1/2 teaspoon honey (optional, for balance)
Pinch of salt
Pinch of black pepper

Required Kitchen Tools

To make Crispy Brussel Sprouts With Dijon Aioli, the following tools will be helpful:

Baking sheet or air fryer basket
Mixing bowl
Small bowl for the aioli
Silicone spatula or spoon
Sharp knife and cutting board
Parchment paper (optional for easier cleanup)

Step-by-Step Instructions

Step 1: Prepare the Brussel Sprouts

Begin by washing and thoroughly drying the Brussel sprouts. Moisture prevents them from crisping, so pat them dry with a clean kitchen towel. Trim off the ends and cut each sprout in half. Removing loose outer leaves is optional but helps achieve a more uniform crisp.

Step 2: Season the Brussel Sprouts

Place the halved sprouts into a large mixing bowl. Drizzle them with olive oil, making sure each piece is evenly coated. Add garlic powder, onion powder, paprika, salt, and black pepper. Toss thoroughly until all the seasonings cling to the vegetables.

Step 3: Arrange on a Baking Sheet

Preheat your oven to 220°C (425°F). Line a baking sheet with parchment paper if desired. Spread the Brussel sprouts cut-side down in a single, uncrowded layer. Avoid overlapping, as this leads to steaming rather than crisping.

If using an air fryer, spread them in the basket in a single layer and cook in batches depending on the size of your appliance.

Step 4: Roast or Air Fry

Oven method:

Roast the Brussel sprouts for 20–25 minutes, flipping them halfway through. They should develop deep caramelized edges and a golden brown center.

Air fryer method:

Air fry at 195°C (385°F) for 13–15 minutes, shaking the basket halfway to promote crisping.

Step 5: Prepare the Dijon Aioli

While the Brussel sprouts cook, make the sauce. In a small bowl, whisk together the mayonnaise, Dijon mustard, lemon juice, minced garlic, honey (optional), and a pinch of salt and pepper. Mix until creamy and smooth. Taste and adjust the acidity or mustard intensity as needed.

The aioli should be velvety, tangy, slightly garlicky, and balanced.

Step 6: Serve

Transfer the hot, crisp Brussel sprouts onto a serving platter and pair them with the Dijon aioli. Serve immediately for the best texture and flavor.

Helpful Tips for Perfect Crispy Brussel Sprouts

1. Dry the Brussel Sprouts Very Well

Any excess moisture prevents browning. Pat them dry thoroughly before seasoning.

2. Use High Heat

High roasting temperatures (above 200°C / 400°F) help develop deep caramelization, ensuring a crispy exterior and tender interior.

3. Place Cut-Side Down

Putting the flat side against the baking sheet maximizes the golden-brown sear.

4. Do Not Overcrowd

Crowded sprouts steam instead of crisp. Use two trays if needed.

5. Add a Drizzle of Balsamic

For a gourmet twist, drizzle a teaspoon of balsamic vinegar or glaze after roasting.

6. Customize the Seasoning

Try adding smoked paprika, chili flakes, Parmesan, or lemon zest.

7. Make the Aioli Ahead

The Dijon aioli tastes even better after chilling for 30 minutes, giving flavors time to develop.

Why This Recipe Works So Well

Crispy Brussel Sprouts With Dijon Aioli deliver an ideal balance of textures and flavors. The sprouts become beautifully crisp thanks to high-heat roasting and a light coating of oil. Their natural nuttiness is enhanced with simple spices that deepen during caramelization. Meanwhile, the Dijon aioli provides brightness, acidity, creaminess, and a hint of garlic.

This contrast makes the dish feel complete and satisfying, even with minimal ingredients. It is equally suitable for casual meals and elegant gatherings.
