You need 1 ingredient. The key ingredients include: ["TOPPING & LOAF (Divided -1/3 for loaf, rest for topping)", "1/2 cup ketchup", "1/3 cup brown sugar", "1 tablespoon lemon juice", "1 teaspoon dry mustard", "MEATLOAF", "2 pounds lean ground beef", "3 slices bread, shredded *SUB", "1/4 cup diced onion", "1 egg, beaten", "1 cube beef bouillon, crumbled", "3 tablespoons lemon juice", "*SUB breadcrumbs or oats (3/4 or 1 cup) for bread", "HELPFUL TIPS AFTER READING ALL THE REVIEWS: The idea of putting 2 pieces of bread on the bottom of the pan before cooking to soak up the grease is GOD SEND! Works like a charm, and you can remove it when you slice everyone their piece. BUT I also take it out at the 1hr mark and drain the excess liquid. I double the sauce, but only to drizzle on top of everyone's slice. When I do double the topping, I add 1T lemon juice OR 1T balsamic vinegar for yummiest topping!", "Substitute bread for 3/4C oats & use green onions instead of onions if you've got picky eaters. Sometimes I dice green peppers too for more flavor.", "If you haven't tried ""Honey Roasted Red Potatoes"" I'd recommend. This meatloaf was liked by everyone over the two other top rated ones on this site!"].
