Preheat oven to 350℉ or 180℃ (convection setting).
Cut the day old bread into thin slices, then soak in water and allow to sit for 5 minutes. Now wring out the bread and put in a large bowl.
200 grams stale bread
Small dice the onions. Over medium heat, melt 1 tablespoon of butter in a large skillet and add the onions. Cook until translucent, about 5 to 10 minutes.
4 yellow onions, 1 Tablespoons butter
Small dice the pickles.
2 large pickles
Add pickles and cooked onions above ingredients into the bowl with the bread. Also add ground meat, eggs, chopped parsley, lemon juice, mustard, and season with salt, cayenne pepper and black pepper. Knead together.
750 grams ground beef, 1 Tablespoon dijon mustard, 1 handful fresh parsley, 2 Tablespoon lemon juice, 2 eggs, 1 ½ teaspoons salt, 1 teaspoon black pepper, ¼ teaspoon cayenne pepper
Melt the remaining butter and use some of it to brush on the inside of a loaf pan. Now add in the meatloaf mixture and shape into a loaf, forming a slight ridge between the meatloaf and the pan.
3 Tablespoons butter
Bake on the bottom rack for about 60 minutes (possibly less time depending on your oven and the pan you use).
Brush butter on top of the meatloaf every 15 minutes until it's done baking.
The internal temperature of the meatloaf should be 160℉ or 71℃ when fully cooked.
Let rest for 10 minutes after baking before slicing.
In the meantime, make the sauce, heat 1 tablespoon of butter in a small pot and sauté the onion for a couple of minutes. Then add in the tomato paste and sauté for 5 minutes. Whisk in the broth and beer and allow to simmer for 5 minutes. Season with salt, pepper, sugar and apple cider vinegar.
1 Tablespoon butter, 2 Tablespoons yellow onion, 2 Tablespoons tomato paste, 100 milliliters broth, 240 milliliters dark beer, 1 Tablespoon dijon mustard, sugar, apple cider vinegar
