French Onion Mac and Cheese


My husband is what I would like to call a “Mac ‘n Cheese purist.”

Some others might call him a kid…

He likes his macaroni and cheese plain. Sometimes he’ll crack some pepper on top and put some ketchup in there… (that’s actually pretty good too, when you’re in a pinch).

So the other day when I was creating this French Onion Mac and Cheese, he was “for sure not going to have any.”

Fine by me! That just means more for yours truly. :)

Well, wouldn’t you know it… once the French Onion Mac and Cheese was done, I served the kids regular mac (including him and his plain jane mac), I sat down with my creamy bowl of delicious flavors, he glanced down at his bowl of lifeless noodles, back to my appetizing bowl, and quickly asked for some French Onion topping.

Mmm. hmmm.

French Onion Mac and Cheese

The french onion soup that I always make is simple. Onions (duh), thyme, and beef broth. I took those same components and made a quick and delicious topping that bursts with flavor on top of a bed of mac and cheese.

The creamy mac is loaded with sweet caramelized onions that are infused with beef broth and fresh thyme (dried thyme works just as good too). Top it all off with some swiss cheese and a little sprinkle of crushed croutons. The croutons give it a delicious crunch to add some texture to this tasty dish.

French Onion Mac and Cheese
  • White Cheddar Macaroni and Cheese boxed dinner, prepared according to box directions
  • 1 tsp olive oil
  • 1 large onion (or two small ones), halved and sliced to make thin strips
  • dash of salt
  • 1 tsp fresh thyme (or dried)
  • 1 tbsp beef broth
  • ½ cup Swiss cheese, shredded
  • ¼ cup crushed croutons
  1. While the macaroni and cheese is boiling, heat the olive oil in a large skillet over medium high heat.
  2. Add the onion and salt and stir occasionally till the onions start to turn brown and caramelize.
  3. Add the beef broth and thyme, and cook until the broth is absorbed. Top your bowl of prepared mac and cheese with some of the onion mixture, sprinkle with a little swiss cheese and crushed croutons.
  4. Enjoy!


  1. Ooooh, love this!!

  2. I’m just a macaroni and cheesist…there is nothing pure about it! bring it on all of it! This looks awesome….

  3. This looks delicious! I bet it is incredible.

  4. Omg. Gotto make this, Mac and cheese is my favorite…maybe a dash of garlic would be perfect. Thanks for the idea!

  5. Not sure about this one–French Onion Soup doesn’t need anything else. Why serve it as one dish when it can be dinner 2 different nights?

    • I totally get what you mean, but when your kids are hungry, and you need a quick dinner- this is a great compromise. Kids get their mac ‘n cheese and you get the tasty upgrade! :) Think of it as adding something more to mac ‘n cheese, not the other way around. 😉

  6. I know that it is extremely tasty but every time I cook this dish I`m thinking about the number of calories it contains but any time when I`m trying to cook something else, much healthier, my husband says that it is not nourishing.

  7. Oh baby does that ever look good!!! What a fun topping for mac and cheese!!!

  8. French Onion soup is my husbands favorite soup, and he loves mac n’ cheese. I can only imagine how much he would LOVE this!

  9. I love french onion soup, so I know I’m going to have to try this french onion version!
