Step 1

Preheat a large saute pan over medium heat. Add the onion and mushrooms. Stirring occasionally, cook until dry and softened, about 10 minutes.

Step 2

Add the garlic and thyme to the pan, stir, and cook for about 30 seconds. Sprinkle the flour into the pan, stir and cook for about 1 minute or until lightly browned.

Step 3

Add the broth and milk, and whisk to dissolve the flour. Return to a low simmer, and cook for about 5 minutes or until thickened. Add pepper to taste.

Step 4

Stir in the tamari, and reduce heat. Taste and adjust seasoning as desired. Serve immediately, or allow gravy to cool, then refrigerate until ready to re-heat and serve.
