Sauté the Mushrooms:
Add sliced mushrooms to the same pan
Cook 3-4 minutes until golden and caramelized
They should release their moisture and look beautifully browned
Season lightly with salt and pepper
Add Aromatics:
Add minced garlic to mushrooms
Cook 30 seconds until fragrant (don't let it burn!)
Stir constantly during this step
Deglaze with Wine:
Remove pan from heat momentarily
Pour in ¾ cup Marsala wine carefully (it will sizzle!)
Return to heat and scrape up brown bits with wooden spoon
This fond adds incredible depth to your sauce
Build the Sauce:
Add 1 cup chicken broth
Bring to a gentle simmer
Cook 5-7 minutes until sauce reduces by about half
It should coat the back of a spoon lightly
Finish with Butter:
Remove from heat
Swirl in remaining 2 tablespoons butter
This creates that glossy, restaurant-quality finish
