Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
Place the trimmed asparagus spears in a single layer on the prepared baking sheet. Ensure they are not overcrowded, as this will steam them rather than roast them.
Drizzle the olive oil over the asparagus. Add the minced garlic, Italian seasoning, salt, and pepper. Use your hands or tongs to toss the asparagus until it's evenly coated with the oil and seasonings.
Arrange the asparagus in a single layer on the baking sheet.
Roast in the preheated oven for 10-12 minutes, or until the asparagus is tender-crisp and slightly browned in spots. Cooking time will vary slightly depending on the thickness of your asparagus spears.
Remove the baking sheet from the oven. Drizzle the fresh lemon juice over the roasted asparagus and toss gently.
Serve immediately. Garnish with lemon zest, if desired, for an extra pop of citrusy flavor.
