FREQUENTLY ASKED QUESTIONS:  Can I cook this longer than 4-5 hours? Yes. Cooking it longer will mean the chicken will get extra tender and will pretty much fall apart when you go to take it out. It won’t be like you see in my pictures below. As long as you don’t mind that, then go for it. You can shred it then put it back into the crock pot to allow it all to be flavored by the juices and serve over mashed potatoes or noodles or rice. It also helps if you have a digital crock pot that lets you cook it for so many hours then it switches over to a keep warm setting. I really recommend those for those of you who need to pop this in the slow cooker before heading into work. Can I make this creamier? Yes, for a creamier flavor profile and texture, mix in a dollop of sour cream or cream cheese before serving for added richness. Or a splash of heavy cream. What can I add for some heat? I know a lot of people always like to add a bit of spice. Try adding a pinch of red pepper flakes for a hint of heat. What to serve with Crock Pot French Onion Chicken? Here are some of my favorite things to serve with this chicken:Side Salad: Fresh greens with a light vinaigrette.Crusty Bread: Some kind of crusty sourdough, sliced French bread or Garlic Bread is perfect for soaking up the flavorful broth.Roasted or Steamed Vegetables: Such as carrots, broccoli, or asparagus.

You don’t want an overly salty dish. You can always add more but you can’t take away. Dijon mustard– I would say if you don’t have dijon mustard then just leave it out. Regular yellow mustard would be too strong a flavor for this recipe.  shredded Swiss cheese– if you want to swap this out, you can use provolone or mozzarella cheese instead. Additionally, Gruyère cheese, which has a similar flavor profile can also be used. parsley– this is an optional ingredient, but I like to use it for color.
