Cook, stirring often, for 10 to 12 minutes or until starting to soften. Reduce heat to low. Cook, stirring occasionally, for 15 to 20 minutes or until onions are golden brown and caramelized. Using slotted spoon, remove onions from skillet.
- In same skillet set over medium heat, melt remaining butter. Cook garlic, stirring, for 30 to 60 seconds or until softened. Sprinkle with flour. Cook for 1 to 2 minutes or until smooth. While whisking, slowly pour in cream and milk; bring to a boil. Reduce heat to low. Cook, stirring occasionally, for 3 to 5 minutes or until slightly thickened. Stir in in chives, thyme, mustard powder, paprika, nutmeg, remaining salt and remaining pepper.
