French Onion Mac N’ Cheese

French Onion Macaroni and Cheese – Creamy homemade mac and cheese with caramelized onion, bacon, and topped with croutons.

Homemade macaroni and cheese is total comfort food for pretty much everyone!  Creamy, cheesy, and so good in pretty much any form.  Today I am combining it with my husbands all time favorite French Onion Soup for an over the top version that you are going to want to try immediately!

Caramelized onions are pretty much the best thing ever, so adding them makes perfect sense.  Pretty sure it is acceptable to add them to anything.  I also added a little bacon.  We all know that bacon makes everything better, so this seemed like a good idea.  Pasta, cheese, caramelized onions, and bacon; are you sold yet?  I made this for the ladies of cooking club this month, and they loved it.  Kind of seriously, over the top, gooey, deliciousness.

This is a baked mac and cheese recipe, so it takes a little longer to make, but it is totally worth it.  The croutons on top get extra crunchy and golden brown and all of the flavors just blend together in perfect harmony.

How to Make Baked Macaroni and Cheese

  1. Pasta – the first step is to boil the noodles. You want to make sure you under cook them because they will continue to cook in the oven and you do not want them to be mushy. 
  2. Sauce – the sauce starts by melting butter and sauteing garlic.  Then you add flour which will help thicken everything.  The milk gets mixed in until everything is smooth. I use skim milk, because that is what we have on hand all the time.  But you can use whatever you have.  Heavy cream or half and half would work and this would be even more decadent and delicious.  
  3. Cheese – stir in the cheeses until they are completely melted and you have a glorious cheese sauce.  I use a mix of 3 cheeses (Monterey Jack, Mozzarella, and Gruyere) to get the best flavor and creaminess that goes with French onion soup.
  4. Bake – everything gets mixed together and put in a casserole dish. Top with the croutons and then you bake until it is hot, bubbly, and the croutons are golden brown.

Homemade macaroni and cheese is pretty darn easy to make and so much better than anything from a box.  It does take more time, but just look at it. It is a totally different food than the stuff from a box, not even fair to compare them.  So if you love French onion soup and you love mac and cheese, this is a definite must!
