Ingredients
  

  • For the Parmesan Asparagus:
  • 1 lb 450g Fresh Asparagus (woody ends trimmed)
  • 2 tbsp Extra Virgin Olive Oil
  • 1/2 cup Parmesan Cheese freshly grated
  • 1 tsp Garlic Powder
  • 1/2 tsp Sea Salt
  • 1/4 tsp Black Pepper
  • 1/2 tsp Lemon Zest for garnish
  • For the Lemon Aioli:
  • 1/2 cup Mayonnaise or plain Greek Yogurt for a lighter version
  • 1 tbsp Fresh Lemon Juice
  • 1 tsp Lemon Zest
  • 1 small Garlic Clove minced or grated
  • Pinch of Salt

Method
 

  1. Preheat and Prep: Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper or a silicone mat for easy cleanup.
  2. Season the Asparagus: Place the trimmed asparagus spears on the baking sheet. Drizzle with olive oil and sprinkle with garlic powder, salt, and pepper. Toss with your hands to ensure every spear is evenly coated.
  3. Add the Cheese: Spread the asparagus in a single layer, ensuring they aren't crowded. Sprinkle the freshly grated parmesan cheese over the top of the spears.
  4. Roast: Bake for 12–15 minutes. Thin spears will take less time; thicker spears may need the full 15 minutes. The asparagus should be tender-crisp and the cheese should be golden and bubbly.
  5. Make the Aioli: While the asparagus roasts, whisk together the mayonnaise (or yogurt), lemon juice, lemon zest, minced garlic, and salt in a small bowl. Cover and refrigerate until ready to serve.
  6. Serve: Transfer the warm asparagus to a serving platter. Sprinkle with fresh lemon zest and serve immediately with the chilled lemon aioli on the side.

Notes

  • Dry for Crunch: Always pat the asparagus completely dry with a paper towel before oiling to prevent steaming and ensure a crispy crust.
  • Fresh is Best: Use freshly grated Parmesan from a block; pre-shredded cheese contains anti-clumping agents that prevent proper melting.
  • Avoid Overcrowding: Spread spears in a single layer with space between them so they roast rather than soften.
  • Aioli Hack: If the garlic flavor is too sharp, let the aioli sit in the fridge for 30 minutes to mellow out.
  • Reheating: Use an air fryer or oven at 350°F (175°C) for 3 minutes to restore the cheese's crispiness; avoid the microwave.
