How to Make Garlic Roasted Brussels Sprouts with Lemon Mustard Parsley Dressing (Step-by-Step)
Follow these simple steps to create a dish that will impress your guests.
Step 1: Preheat Your Oven
Set the oven to 400°F (200°C) and enjoy the warmth it brings to your kitchen during the cold December days.
Step 2: Prepare the Brussels Sprouts
In a large bowl, combine the halved Brussels sprouts with sliced garlic, olive oil, salt, and pepper. As you mix, savor the earthy aroma of fresh Brussels sprouts and garlic mingling together.
Step 3: Roast the Sprouts
Spread the mixture evenly on a rimmed baking sheet. Bake for about 25-30 minutes, tossing halfway through, until the Brussels sprouts are golden and crispy, with a slight jiggle and perfectly charred exterior.
Step 4: Make the Dressing
While the sprouts roast, whisk together the fresh lemon juice, Dijon mustard, and chopped parsley in a small bowl. Taste it - the citrus tang and creamy mustard create a vibrant dressing that enhances the flavors of the Brussels sprouts.
Step 5: Serve
Drizzle the Lemon Mustard Parsley Dressing generously over the warm Brussels sprouts as soon as they come out of the oven. Experience the spectacular combination of hot, roasted vegetables and zesty dressing.

Common Mistakes to Avoid
- Overcrowding the pan: If the Brussels sprouts are too close together, they won't roast properly, resulting in a soggy texture instead of that satisfyingly crispy finish.
- Using old Brussels sprouts: Freshness matters! Always opt for firm, vibrant green Brussels sprouts for the best taste and texture.
- Skipping the seasoning: Be generous with salt and pepper; under-seasoning can lead to bland results, and we want those flavors to shine.
Tips and Tricks for Success
- For an extra flavor boost, try adding a sprinkle of red pepper flakes before roasting for a spicy kick.
- This dish is incredibly versatile and pairs wonderfully with holiday mains like turkey or glazed ham.
- You can make the dressing ahead of time; just store it in an airtight container in the refrigerator for up to a week.
Variations
- Substitute Brussels sprouts with green beans or asparagus for a different vegetable option.
- Use apple cider vinegar instead of lemon juice for a different flavor profile in the dressing.
- Add bacon or pancetta for a savory twist on the classic recipe.
How to Serve
- Drizzle the Lemon Mustard Parsley Dressing over the roasted Brussels sprouts right before serving.
- Pair with roasted meats, such as turkey or ham, for a festive meal.
- Serve as a warm side dish at holiday gatherings or family dinners.

Make Ahead and Storage
- Make Ahead: Prepare the dressing ahead of time and store it in an airtight container in the refrigerator for up to a week.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.
- Reheating: Reheat in the oven briefly to re-crisp before serving.
- Freezing: Not recommended for best texture and flavor.
