Combine half and half, chicken broth, Worcestershire sauce, dried parsley, dried basil, mustard powder, dried thyme, and ground sage in a medium measuring cup with a spout. Set aside.

Measure out remaining ingredients before beginning. Plan to start boiling pasta water when mushrooms are nearly finished cooking.
03 -
Heat olive oil in a deep 12-inch skillet over medium-high heat. Add half the mushrooms, allowing them to brown undisturbed on each side for 3-4 minutes. Leave space between pieces to promote frying rather than steaming. Add more olive oil if needed. Remove when golden brown and set aside. Repeat with remaining mushrooms.

Turn off heat and allow pan to cool slightly. Add white wine to the same skillet and set heat to medium. Use a silicone spatula to scrape fond from bottom of the pan. Simmer until liquid reduces by half, about 4 minutes.
05 -
Melt butter in the skillet and add minced garlic. Cook for 2 minutes. Stir in flour and cook for 1-2 minutes, stirring continuously.
06 -
Reduce heat to medium-low. Gradually add the prepared sauce mixture in small splashes, stirring continuously. Bring to a gentle boil, then reduce to a simmer.

While sauce simmers, cook ravioli according to package instructions. Set a timer to avoid overcooking. Drain once cooked.

Reduce heat to low and stir in Asiago and Parmesan cheese until combined. Add the reserved mushrooms back to the sauce.

Either plate the ravioli and spoon sauce over top, or add ravioli directly to the skillet and carefully combine. Garnish with fresh parsley.
