Ingredients

• 2 cups (peeled, cubed) butternut squash
• 2 cups (halved) Brussels sprouts
• 1.5 cups (cut into thick coins) carrots
• 1 large (cut into wedges) red onion
• 3 tablespoons (divided) olive oil
• 1 teaspoon salt
• 0.5 teaspoons black pepper
• 2 tablespoons (chopped, for garnish) fresh parsley
• 2 tablespoons (freshly squeezed) lemon juice
• 1 tablespoon Dijon mustard
• 1 teaspoon maple syrup
• 1 clove (minced) garlic

Directions

Step 1

Preheat your oven to 425°F (220°C) and line two large baking sheets with parchment paper.

Step 2

In a large mixing bowl, combine the butternut squash, Brussels sprouts, carrots, and red onion. Drizzle with 2 tablespoons of olive oil, then sprinkle with salt and black pepper. Toss to coat the vegetables evenly.

Step 3

Spread the vegetables out in a single layer on the prepared baking sheets, making sure not to overcrowd them.

Step 4

Roast the vegetables in the preheated oven for 30-35 minutes, flipping them halfway through, until they are tender and lightly caramelized.

Step 5

While the vegetables are roasting, prepare the vinaigrette. In a small bowl or jar, whisk together the remaining 1 tablespoon of olive oil, lemon juice, Dijon mustard, maple syrup, and minced garlic until well combined.

Step 6

Once the vegetables are cooked, transfer them to a serving platter or large bowl.

Step 7

Drizzle the lemon and mustard vinaigrette over the roasted vegetables, tossing gently to coat evenly.

Step 8

Garnish with chopped fresh parsley and adjust seasoning if needed. Serve warm or at room temperature and enjoy!
