I just made a batch of this to put in the freezer, and it turned out great, so figured I’d post the “recipe” here. Recipe within quotes, because I never use the same amount of ingredients and often add or remove ingredients. Farfar = Grandpa in Swedish, hence the name of it, because Dad gave me his basic ingredients and I added to that.
What you need:
Yellow Onion
Ground Beef
Beef Bouillon
Heavy Cream
Flour
Soy Sauce
Ketchup
Garlic (Fresh)
Oregano
Start by dicing the onion and throw it in a small pan. Saute meat in a large pan until fully cooked. Add diced onions and mix together. Add chopped garlic. Lower to medium to high heat and add the heavy cream. Then add beef bouillon, soy sauce and ketchup (more than you think, this is what gets the sauce a dark brown to red color) and stir. Let it cook for a bit, then add some flour to thicken the sauce. I have no idea how much, I just wing it. Once the sauce is somewhat thick, top it off with Oregano and let it sit on low heat for a while. It should look something like this when done:

Yum.
Quick & easy, serve with spaghetti and a side salad.
