01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - Arrange trimmed asparagus in a single layer on the lined baking sheet. Drizzle with olive oil, season with sea salt and black pepper, and toss to coat evenly.
03 - Roast the asparagus for 10 to 13 minutes, until tender and lightly caramelized.
04 - While asparagus roasts, melt unsalted butter in a small skillet over medium heat. Add sliced almonds and toast, stirring, until golden brown, about 2 to 3 minutes.
05 - Add minced garlic and lemon zest to the skillet; cook for 30 seconds until fragrant. Remove from heat and stir in fresh parsley and Parmesan cheese.
06 - Transfer roasted asparagus to a platter. Top generously with lemon almond crumble. Serve immediately with lemon wedges on the side.
