Ingredients

• 500 g Brussels sprouts
• 3 tbsp Olive oil
• 1 tsp Salt
• 0.5 tsp Black pepper
• 1 large Yellow onion
• 2 tbsp Unsalted butter
• 2 cloves Garlic
• 2 tbsp Dijon mustard
• 100 ml Heavy cream
• 50 ml Chicken or vegetable stock
• 1 tsp Honey

Directions

Step 1

Preheat your oven to 200°C (400°F).

Step 2

Trim the stems off the Brussels sprouts and remove any discolored outer leaves. Slice larger sprouts in half for even cooking.

Step 3

In a large bowl, toss the Brussels sprouts with 2 tablespoons of olive oil, salt, and black pepper. Spread them evenly on a baking sheet lined with parchment paper.

Step 4

Roast the Brussels sprouts in the preheated oven for 18-20 minutes, flipping them halfway through, until they are golden and tender.

Step 5

While the sprouts roast, finely chop the yellow onion and mince the garlic cloves.

Step 6

Heat 1 tablespoon of olive oil and 2 tablespoons of unsalted butter in a large skillet over medium heat.

Step 7

Add the chopped onion to the skillet and sauté for 5-7 minutes, stirring occasionally, until softened and lightly caramelized.

Step 8

Add the minced garlic to the skillet and cook for an additional minute, until fragrant.

Step 9

Stir in the Dijon mustard, heavy cream, chicken or vegetable stock, and honey. Simmer on low heat for 3-4 minutes, allowing the sauce to thicken slightly.

Step 10

Taste the sauce and adjust seasoning with additional salt or pepper, if needed.

Step 11

Once the Brussels sprouts are done roasting, transfer them to the skillet with the sauce. Toss to coat the sprouts evenly in the onion mustard sauce.

Step 12

Serve warm as a side dish or enjoy as a light vegetarian main course.
