Heat oil in a pan, sauté onion and garlic. Then add the mushrooms, broth, tamari, and spices. Pour in the cream mixture (cornstarch + canned coconut milk). Taste and adjust seasonings.
For homemade fried onions, simply chop one onion, soak it in plant-based milk for about 30 minutes, then transfer it to a bowl with flour and fry in oil.
