Step 1

Preheat oven to 350°F and adjust rack to middle position.

Step 2

Heat the butter over medium heat in a large skillet. Add carrot, celery and bell pepper and saute for 5-7 minutes, until soft. Make a well in the center of the pan and add the salt and thyme and stir until fragrant (about 30 seconds), then stir into the vegetables. Remove the pan from heat, let the mixture cool for about 10 minutes.

Step 3

Place the eggs and liver in the bowl of a food processor or blender and blend until smooth. Place the ground beef, almond flour, and egg mixture in a large bowl. Add the cooled vegetables and stir until combined. Pour the mixture into a 9×11-inch baking dish and form into a large loaf. Arrange the bacon in a criss-cross pattern on top and using a pastry brush, brush with maple syrup or ketchup (if using). Pour 3/4 cup of water on the bottom of the pan (the loaf will be surrounded by water. This keeps the meatloaf moist). Bake for 1 1/2 hours until golden brown. Let meatloaf rest for 10 minutes before serving.
