Lamb Ragu Bucatini

Melt butter in a large high-sided skillet over medium; add onion, and cook, stirring often, until softened but translucent, about 6 minutes. Add garlic, and cook, stirring constantly, until fragrant, about 1 minute. Add lamb, and cook, stirring often and breaking up meat using a wooden spoon, until lightly browned, 6 to 8 minutes. Add wine; reduce heat to medium-low, and simmer until reduced by half, 6 to 8 minutes. Add stock, and simmer until reduced by half, 6 to 8 minutes. Add tomatoes with juices, breaking up loosely using a wooden spoon; stir in fresh oregano, coriander, bay leaves, and 2 teaspoons of the Espelette pepper.

Reduce heat in skillet to medium-low; simmer until sauce thickens and becomes bubbly, about 20 minutes, stirring every few minutes to prevent burning. Add salt and additional Espelette pepper to taste. Remove and discard bay leaves.

While sauce simmers, bring a large pot of lightly salted water to a boil over medium-high. Add pasta, and cook according to package directions until al dente. Drain, reserving 1/2 cup cooking water; set aside until ready to use.

Stir together cheese, lemon zest, and dried oregano in a small bowl. Set aside.

Add cooked pasta, olives, reserved 1/2 cup cooking water, and remaining 2 teaspoons Espelette pepper to sauce in skillet, stirring constantly until sauce coats pasta. Divide evenly among 4 bowls, and top evenly with reserved cheese mixture.
