Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Trim the woody ends off the asparagus and place them on the baking sheet, tossing with half of the olive oil, sea salt, and black pepper.
In a shallow bowl, whisk together the almond flour, dried rosemary, dried thyme, and garlic powder to create the herb crust mixture.
Pat the lamb chops dry with a paper towel and brush both sides of each chop with a thin layer of Dijon mustard.
Press the mustard-coated lamb chops into the almond flour herb mixture until they are evenly encrusted on all sides.
Heat the remaining olive oil in a large oven-safe skillet over medium-high heat and sear the lamb chops for 2 minutes per side until a golden crust forms.
Transfer the skillet to the oven along with the asparagus tray; roast for 8 to 10 minutes or until the lamb reaches your preferred internal temperature.
Remove from the oven and squeeze the fresh lemon juice over the roasted asparagus before serving alongside the lamb.
