MRS. KOSTYRA'S MEATLOAF

Steps:

• Heat oven to 375 degrees. Line a rimmed baking sheet with parchment paper, then fit the sheet with a wire rack. Brush an 10-by-4 3/4-by-3-inch loaf pan with oil, and place on rack; set aside. Place bread in the bowl of a food processor fitted with the steel blade; pulse until fine crumbs form. Transfer to a medium bowl, and add ground beef.
• Place onion, garlic, celery, carrots, and parsley in the bowl of a food processor fitted with the steel blade; pulse until fine. Add to meat mixture, using hands to mix well. Add egg, 1/2 cup ketchup, 2 teaspoons dry mustard, salt, and pepper; use hands to combine thoroughly. Transfer to prepared loaf pan.
• Combine remaining 1/2 cup ketchup, remaining teaspoon dry mustard, and brown sugar in a bowl; stir until smooth.
• Brush mixture over meatloaf; place pan in oven, atop prepared wire rack set on parchment-lined baking sheet. Cook until a meat thermometer inserted in the center reads 160 degrees, about 90 minutes. If top gets too dark, cover with foil and continue baking.
