Ingredients

• 1 lb asparagus spears
• 1 medium red onion
• 2 tbsp olive oil
• 2 large garlic cloves
• 0.5 tsp salt
• 0.25 tsp black pepper
• 1 tbsp balsamic vinegar
• 0.25 cup parmesan cheese (optional)

Directions

Step 1

Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper or lightly grease it with olive oil.

Step 2

Trim the woody ends off the asparagus spears, about 1-2 inches from the bottom, and discard them.

Step 3

Peel and slice the red onion into thin wedges.

Step 4

Peel and finely chop the garlic cloves.

Step 5

Place the asparagus spears and red onion slices on the prepared baking sheet.

Step 6

Drizzle the olive oil evenly over the vegetables and sprinkle with chopped garlic, salt, and black pepper. Toss gently to ensure everything is well-coated.

Step 7

Spread the vegetables out in a single layer on the baking sheet to allow for even roasting.

Step 8

Roast in the oven for 15 minutes, then remove the sheet and drizzle the balsamic vinegar evenly over the vegetables.

Step 9

Return to the oven and roast for an additional 5 minutes, or until the asparagus is tender and the onions are slightly caramelized.

Step 10

Optional: Sprinkle grated parmesan cheese over the vegetables immediately after removing them from the oven for a savory finishing touch.

Step 11

Serve warm as a side dish with your favorite main course.
