Preheat your oven to 375°F (190°C) and grease a large baking dish with a little olive oil.
In a large bowl, whisk together olive oil, minced garlic, chopped rosemary, thyme, sage, Dijon mustard, honey, salt, black pepper, paprika, lemon juice, and lemon zest until well combined.
Place the turkey breast inside the bowl with the marinade and ensure it is well coated. For optimal flavor, cover and marinate in the refrigerator for at least 1 hour, or up to overnight.
Remove the turkey from the marinade and place it in the prepared baking dish. Pour any remaining marinade over the turkey to enhance the flavor.
Roast the turkey in the preheated oven for about 50-60 minutes, or until the internal temperature reaches 165°F (75°C). Baste occasionally with the pan juices for added moisture.
Once cooked, remove the turkey from the oven and let it rest for 10-15 minutes covered with aluminum foil. This ensures the juices redistribute for a moist slice.
Slice the turkey breast into thick, juicy slices and arrange on a serving platter. Garnish with fresh parsley if desired.
