Ingredients

• 500 grams Brussels sprouts
• 1 large Yellow onion
• 2 tablespoons Olive oil
• 1 teaspoon Salt
• 0.5 teaspoons Black pepper
• 3 large Egg yolks
• 115 grams Unsalted butter
• 1 tablespoon Freshly squeezed lemon juice
• 1 tablespoon Water
• 0.25 teaspoons Cayenne pepper

Directions

Step 1

Preheat your oven to 200°C (400°F).

Step 2

Trim the ends of the Brussels sprouts and remove any discolored outer leaves. Slice them in half lengthwise.

Step 3

Peel the onion and slice it into thin rings.

Step 4

Place the Brussels sprouts and onion slices on a baking sheet. Drizzle with olive oil, and sprinkle with salt and black pepper. Toss to coat evenly.

Step 5

Spread the vegetables in a single layer on the baking sheet and roast in the oven for 20-25 minutes, flipping them midway, until the Brussels sprouts are tender and caramelized, and the onions are golden brown.

Step 6

While the vegetables are roasting, prepare the hollandaise sauce. Begin by melting the butter in a small saucepan over low heat. Once melted, set aside to cool slightly.

Step 7

In a heatproof bowl, whisk together the egg yolks, water, and lemon juice until well combined.

Step 8

Place the bowl over a pot of simmering water, making sure the bottom of the bowl does not touch the water. Whisk constantly until the mixture thickens and doubles in volume, about 3-4 minutes.

Step 9

Remove the bowl from the heat and slowly drizzle in the melted butter, whisking continuously to emulsify. Season with a pinch of cayenne pepper and additional salt if desired.

Step 10

Once the Brussels sprouts and onions are done roasting, transfer them to a serving dish.

Step 11

Drizzle the hollandaise sauce over the warm vegetables, or serve it on the side as a dipping sauce.

Step 12

Serve immediately and enjoy the rich, buttery flavor of the dish!
