Preheat oven to 375 degrees F. Coat a large sheet pan with nonstick cooking spray.
In large bowl, combine all meatloaf ingredients. Mix well to combine. Form mixture into a log (about 4-5 inches thick) on the sheet pan.
FOR THE POTATOES:
Toss the potatoes with olive oil. Spread around the sheet pan, surrounding the meatloaf. Sprinkle generously with salt and pepper.
Bake for 45 minutes.
FOR THE MEATLOAF GLAZE:
In a small bowl, mix all ingredients together for the sauce. Spread over meatloaf, then return to oven. Bake additional 15 minutes, until potatoes are tender.
Rest meatloaf 10 minutes before slicing. Cut meatloaf into slices and serve with potatoes.
