In a food processor, combine shallot, garlic, mushrooms, and sage leaves. Pulse until finely chopped.
In a large skillet, melt 3 tablespoons butter over medium heat. Continue to cook until it begins to turn golden and smell nutty (about 3 minutes).
Add the mushroom mixture along with the thyme sprigs, salt, pepper, parsley, coriander, nutmeg, and paprika.
Sauté for 10–15 minutes, stirring occasionally, until most of the liquid has evaporated and the mushrooms begin to brown.
Remove and discard the thyme sprigs.
Stir in maple syrup, cooked farro, and pumpkin seeds. Cook for another 1–2 minutes, just to combine.
