Hamburg Steak with Demi-Glace Sauce
Japanese Hamburg Steak (Hambāgu) differs from its American counterpart—it is a standalone main dish, typically served with a rich demi-glace sauce and side dishes. The secret to its tender, juicy texture lies in the addition of breadcrumbs and milk, as well as extremely finely processed onions. Your Geedel vegetable chopper is perfect for handling both of these crucial tasks.
Ingredients:
For the hamburg patties:
- 400g mixed beef and pork mince
- 1 onion
- ½ cup breadcrumbs
- ¼ cup milk
- 1 egg
- Salt, black pepper, nutmeg powder
For the demi-glace sauce:
- ¼ onion
- 1 carrot
- 1 celery stalk
- 2 cups beef stock
- 2 tbsp tomato paste
- 2 tbsp soy sauce
- 1 tbsp Worcestershire sauce
- 1 tbsp butter (for finishing)
Instructions:
1. Prepare fine onion paste (key step):
Cut one onion into chunks. Attach the chopping blade to the Geedel food chopper, add the onion chunks, and turn the handle continuously until the onion reaches a very fine, almost paste-like consistency. Sauté in a little oil until transparent and caramelized, then allow to cool completely.

2. Mix the meat patty mixture:
Replace the chopping blade with the mixing paddle. Add the minced meat, cooled onion paste, breadcrumbs, milk, egg, and seasonings to the container. Secure the lid and turn the handle steadily at a low speed until all ingredients are evenly and smoothly combined and the mixture becomes sticky.
3. Cook the patties and prepare the sauce:
Divide the meat mixture into two portions and shape into oval patties. In a frying pan, cook over medium heat until both sides are browned. Add a little water, cover, and steam-fry until fully cooked inside. Remove and keep warm.
Make the sauce: Cut ¼ onion, carrot, and celery into chunks, then quickly chop using the chopping blade in the food chopper. Sauté in the remaining pan oil until fragrant, then add tomato paste, beef stock, soy sauce, and Worcestershire sauce. Bring to a boil and simmer until the sauce thickens. Remove from heat and stir in the butter.
4. Serve:
Plate the hamburg steaks, drizzle with the warm demi-glace sauce, and serve with rice and vegetables.
Summary:
The success of this Japanese yōshoku dish heavily relies on the fineness of the onion and the even mixing of the meat. The Geedel manual vegetable chopper easily meets these core requirements—its low-speed mixing function also prevents overworking the meat, keeping it tender and juicy. It is the ideal tool for recreating this soft, flavorful taste of home-style Japanese cooking.
