Savoury plant-based Swedish meatballs crafted from sautéed brown mushrooms, rolled oats, caramelized onions, and allspice, served in a velvety cream gravy with lingonberry jam.
Sauté minced mushrooms and onions in butter for 8 minutes until all moisture evaporates. Let cool.
Combine mushrooms, oats, eggs, cheese, allspice, white pepper, and salt. Mix thoroughly and chill 20 minutes to firm up.
Roll into small balls with damp hands. Fry in foaming butter over medium heat for 6-8 minutes until deeply golden.
Whisk flour into pan drippings, whisk in broth, cream, and soy sauce. Simmer 3 minutes. Pour over meatballs and serve with potatoes and lingonberries.
