Preheat oven to 350 degrees F (175 degrees C). Stir the ground beef, crushed French fried onions, cheddar cheese, and onion soup mix in a large bowl until well combined. Whisk the eggs, ketchup, and steak sauce in a separate bowl until smooth. Mix the egg mixture into the meat until evenly combined.
Press into a 9x5 inch loaf pan.
Bake in preheated oven until the meatloaf reaches 160 degrees F (71 degrees C) and is no longer pink in the center, 45 to 60 minutes.
