01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or foil and place a wire rack atop if available.
02 - Divide asparagus into 8 bundles, each containing 3 spears.
03 - Drizzle asparagus with olive oil and toss to coat. Evenly sprinkle with black pepper, garlic powder, and smoked paprika if using.
04 - Wrap each bundle tightly with one slice of beef bacon, starting just below the tips and spiraling downward to secure. Position bundles seam-side down on the prepared rack or baking sheet.
05 - Roast bundles for 18 to 20 minutes, until beef bacon is crisp and asparagus is tender.
06 - Transfer bundles to a serving platter. Garnish with chopped parsley and serve with lemon wedges if desired.
