⅛ Cup Bread Crumbs, ¼ Teaspoon Salt, ⅛ Teaspoon Black Pepper Ground, ½ Teaspoon Onion Powder, ½ Teaspoon Garlic Powder, ½ Teaspoon Paprika, ¼ Teaspoon Dill Seeds, ¼ Teaspoon Coriander Seeds Ground, ½ Egg
Combine the burger mass so that it is well mixed.
Shape into equal-sized balls. Place them on a clean surface and gently press down to shape circle burger patties.
Prep fresh produce
Dice onion, chop garlic, and slice mushrooms.
1 Onion, 1 Piece Garlic Clove, 8 Ounce Mushroom
Keep all the ingredients separate at the side nearby.
To cook the dish
Heat up a skillet with 1 tablespoon olive oil and wait for it to get hot enough. Keep over a medium to high heat setting.
3 Tablespoon Olive Oil
Place hamburger beef patties into the pan and keep the same heat setting.
Cook meat on both sides until cooked through. Reduce to a medium heat setting if it's too hot.
Take the meat from the pan and keep it aside but keep the pan hot, on a slow flame. Add 2 tablespoon olive oil.
3 Tablespoon Olive Oil
Stir all-purpose-flour into the oil. This is your roux now. It should be smooth without lumps.
2 Tablespoon All-purpose Flour
Stir onion into the skillet and sauté until it has softened a bit. Keep over a medium heat setting.
1 Onion
Stir in chopped garlic and cook and mix for a minute or two. Be careful that the garlic doesn't burn on, keep on a slower heat setting.
1 Piece Garlic Clove
Increase the heat again and add the sliced mushrooms. Mix and sauté. The mushrooms will reduce considerably.
8 Ounce Mushroom
Season with black pepper, salt, and grated nutmeg.
¼ Teaspoon Black Pepper Ground, ½ Teaspoon Salt, pinch Nutmeg
Pour in beef stock and add the dijon mustard. Mix it all and keep it over a medium heat setting.
1 Cup Beef Stock, 1 Tablespoon Dijon Mustard
Stir cook and watch the sauce thicken. Cook until you are satisfied with the consistency.
Place meat slices back into the pan into the sauce. Serve up.

Notes
In the US get a pack of 8-ounce button mushrooms (which makes about 226 grams). In the rest of the world, the packs tend to be 200 or 250 grams, so use a pack of 200 or 250 in that case.
The steak ingredient quantity can be doubled too, prep 4 patties for this dish and freeze the other 4. The process images in the post and the video show the meat quantity for 8 patties.
You can use ready-made steaks in this recipe instead of homemade ones.
The leaner the ground beef the less flavorful the meat. Try getting ground beef with at least 20-25% fats. (Mine is lean in the video and pictures because that's what we get...)
It's optional to add the dill seeds and ground coriander seeds. Skip them if they are hard to get by. Add them if you want some great flavors in your burger meat.
