Return empty skillet to stovetop and reduce heat to medium-low. Add 3 tablespoons ghee and warm ghee until melted, swirling and tilting pan occasionally to distribute ghee across entire skillet.
When ghee has melted, sprinkle 3 tablespoons arrowroot powder into skillet, then vigorously whisk arrowroot into melted ghee until fully combined.
Once combined, slowly pour 2 cups compliant beef broth into skillet in small increments, whisking constantly to incorporate beef broth into arrowroot roux. Continue until all beef broth has been added and mixture has become thin and smooth.
Increase heat under skillet to medium and continue whisking mixture until slightly thickened.
Once mixture has thickened, remove skillet from heat and let cool slightly. Slowly pour 1 cup unsweetened, full-fat coconut cream into skillet and whisk to incorporate fully.
Return skillet to heat. Add 1 teaspoon compliant Dijon mustard, 1 teaspoon salt, 1 teaspoon freshly cracked black pepper, and 1 dash coconut aminos (if desired). Whisk mixture until all ingredienst are fully incorporated, then reduce heat under skillet to medium-low.
Simmer mixture 3 to 5 minutes, stirring occasionally, until gravy has thickened to desired consistency.
When satisfied with consistency, return meatballs to skillet. Coat meatballs with gravy on all sides and simmer just until meatballs are heated through.
