French Onion Chicken Macaroni and Cheese is all the flavor of French Onion Soup with cheesy noodles and chicken. The ultimate comfort food! Try my French Onion Deviled Eggs (yes, really!) for another recipe with a French Onion taste.
I have been on a French Onion kick lately. It had been a while since my Homemade Onion Soup Mix, but lately, I have expanded to making French Onion Dip, French Onion Deviled Eggs, Skillet Onion Dip, and my French Onion Zucchini Bake. I told you, there have been a lot of French Onion dishes around here! I must confess, French Onion Chicken Macaroni and Cheese has to be my favorite! Macaroni and Cheese has really grown up, as I like to say. The variations that are possible with cheesy noodles are endless and fun! Best of all, this dish is satisfying and filling enough to be a meal!
To be honest, I was originally not going to add chicken to this recipe. However, I thought it could use a little more substance, even though it is delicious both ways! By adding the chicken, it is more of a full meal, with the protein keeping your hunger at bay for longer!
There are three parts to making the French Onion Chicken Macaroni and Cheese Recipe. First, it’s all about caramelizing onions, followed by the macaroni and cheese and the topping. Make sure you have the following ingredients on hand to complete the recipe.
Caramelized Onions Ingredients
Macaroni and Cheese Ingredients
Preheat the oven to 350°F.
The first step in this recipe that needs attention is the process of carmelizing the onions. Caramelizing onions is an amazing way to pull out the naturally sweet flavor of a very simple ingredient. Yellow onions have a natural sweetness that explodes when you slow cook them in butter or oil. The trick here is to take your time. Heat a skillet to medium-high heat before you add the oil, butter, and onions. Cover the onions, and cook on low for 25-30 minutes. After the onions have softened, increase the heat to medium and cook the onions until they are a golden brown. Remove the onions from the heat, cover them, and set aside until you add them to the macaroni later.
After the onions have been caramelized, begin to put together the ingredients to add to your cooked noodles. By the way, have you preheated the oven to 350° yet? You will need the oven at the end to bake the French Onion Chicken Macaroni and Cheese. Take out your saucepan and start heating up and mixing all the cheeses, chicken, and spices together. There are a couple of times where you will be taking the pan on and off the heat, so be aware of that.
Start by heating the butter over medium heat. Add the flour and whisk for a couple of minutes. Alright, it’s time to remove the pan from the heat for the first time. Gradually pour in the warm milk and beef stock, whisking constantly. Place the pan back on the heat and keep whisking! After 3-5 minutes, add the salt, garlic powder, ground mustard, and cayenne pepper and stir to combine. Remove from the heat for the second and final time. This is the point where you add the cheeses and caramelized onions. Pour this mixture over your cooked pasta, stirring until the cheese has melted. Finally, add the shredded rotisserie chicken and mix everything together. Do NOT put the saucepan over heat, thinking it will help melt the cheese! Keep reading to understand this demand…
I am on a mission to make sure no one has grainy homemade mac n cheese ever again… and in my research discovered this awesome tip. Do NOT put the pan back over the heat to melt the cheese. The ingredients in the pan are already hot enough to do the job of melting the cheeses. If you get cheese too hot that is when you will end up with a grainy texture. After you have stirred in the cheese, pour the mixture over the cooked noodles, and watch the melting commence!
To put the finishing touches on your French Onion Chicken Macaroni and Cheese, it’s time to add the topping. Simply layer the top of the macaroni and cheese with shredded Gruyere cheese. Bake it in the oven for 12-15 minutes, or until the cheese is golden brown. Before serving, add salt and pepper to taste, as well as a bit of fresh thyme for an added, subtle, taste. Serve this with my homemade breadsticks and garlic roasted asparagus for a complete meal!
