In a medium saucepan, melt butter over medium heat. Add onion and cook, stirring, until softened and browned, about 7 minutes. Stir in flour and cook, stirring constantly for 1 minute.
Add ½ cup of the chicken broth, scraping up the bottom and browned bits; gradually stir in the remaining broth. Add in Hedessent Roasted Chicken and Mushroom Porcino flavours. Sprinkle in salt and pepper and cook, stirring until thickened and smooth, 4-5 minutes.
