1 tablespoon butter
1/4 cup minced onion
2 cloves garlic, minced
1 1/2 teaspoons salt
1 1/2 teaspoons freshly ground black pepper
2 pounds extra-lean ground beef
3 slices bread, toasted and crumbled
7 buttery round crackers, crushed
1 egg, lightly beaten
3 1/2 tablespoons sour cream
1 1/2 tablespoons Worcestershire sauce
1 (15 ounce) can tomato sauce, divided
1/4 cup milk (optional)
3 tablespoons ketchup
Preheat oven to 350 degrees F (175 degrees C).
Melt the butter in a skillet over medium heat, and cook the onion and garlic 5 minutes, until onion is tender. Remove from heat, and season with salt and pepper.
In a large bowl, mix the onion and garlic, beef, crumbled bread, crushed crackers, egg, sour cream, Worcestershire sauce, and 1/2 can tomato sauce. Gradually stir in the milk 1 teaspoon at a time until mixture is moist, but not soggy. Transfer the mixture to a 5×9 inch loaf pan.
Bake uncovered in the preheated oven 40 minutes. Increase oven temperature to 400 degrees F (200 degrees C), and continue baking 15 minutes, to an internal temperature of 160 degrees F (70 degrees C).
In a small bowl, mix the remaining tomato sauce and ketchup. Pour over the top of the meatloaf, and continue baking 10 minutes.
