Prep the Dates: Use a paring knife to make a slit lengthwise in each Medjool date. Remove the pit and set the dates aside on a parchment-lined baking sheet.
Mix the Filling: In a mixing bowl, combine the ground lamb, minced onion, garlic, and fresh herbs.
Season: Add the cumin, cinnamon, saffron, salt, and pepper to the lamb mixture. Mix thoroughly by hand until spices are evenly distributed.
Stuff: Stuff each date generously with the lamb mixture (roughly 1-2 teaspoons per date).
Bake: Bake at 350°F (175°C) for 15–20 minutes until the lamb is fully cooked through and the dates are slightly caramelized.
Garnish: Remove from the oven and immediately press slivered almonds into the warm lamb. Serve warm.
