Preheat your oven to 350°F (175°C). Yes, we’re warming up the loaf, not the drama.
n a large bowl, mix ground beef, breadcrumbs, milk, egg, McCormick Meatloaf Seasoning, and optional onion or garlic. Don’t overwork it; we’re aiming for a tender loaf, not shoe leather.
Add ketchup or tomato sauce and combine just until evenly moistened. A few short folds beats overmixing any day
Shape the mixture into a loaf on a lightly greased sheet or in a loaf pan. Some people like a slight oval; your call.
Brush a little extra ketchup on top if you’re feeling fancy. Bake for 45–55 minutes, until the internal temp hits 160–165°F (71–74°C).
Let it rest 5–10 minutes before slicing. The juices settle, and you don’t burn your tongue on the first bite.
