Step 1

Pre-heat oven to 425 degrees. Halve, peal and thinly slice onion. Mince a few slices until you have about 2 tbsp.

Step 2

In a large bowl, combine beef, panko, garlic powder, stock concentrate, minced onion, ketchup, salt and pepper. Form beef mix into two 1 inch tall loaves. Place on baking sheet. Brush tops with a small amount of ketchup. Roast on middle rack until cooked, 15-20 minutes.

Step 3

While meatloaf cooks, heat a drizzle of oil in a large pan/skillet over medium-high heat. Add sliced onion and cook, stirring occasionally, until browned and softened, 8-10 minutes. Add 1 tsp sugar and a splash of water. Cook, adding more water as necessary until onion is caramelized and jammy, 2-3 minutes. Season with salt and pepper. Turn off heat and transfer onion to small bowl.

Step 4

Toast bread until golden brown. While broad toasts, combine horseradish sauce, mayonnaise, and half the mustard.

Step 5

Lay toasted bread out on a cutting board. Spread half the bread slices with caramelized onion; spread remaining bread slices with sauce. Cut each meatloaf crosswise into four slices, fan out slices over bread topped with caramelized onion. Close sandwiches and cut in half.
