Anything with caramelized onions has my name written all over it! This recipe is absolutely amazing! So full of flavor & probably one of my new favorites.

I saw the recipe on Pinterest. I knew I wanted to change it up a tad because it just didn’t seem quite “onion-y” enough to be like a french onion soup in pasta form, so I adjusted it to my likings.

This doesn’t make a lot, just enough for 4 people, so if you want to use a whole 16oz box of penne, double the sauce & use a 9×13″ baking dish, but put this on your make soon list because it is that good!

French Onion Pasta

French Onion Pasta


  • 1 Tbsp extra virgin olive oil
  • 1 large sweet onion, julienned
  • 1/2 tsp kosher salt
  • *1/2 tsp sugar, optional
  • 2 cloves garlic, minced
  • 2 Tbsp flour
  • 1 packet onion soup mix
  • 2 cups chicken stock or beef stock
  • 1 cup half & half
  • 1/2 cup shredded mozzarella cheese
  • 2 cups whole wheat penne pasta


  1. In a large non-stick pot or skillet, heat oil & add onion. Cook on medium-low heat for 10 minutes. Add kosher salt & sugar if desired, stir & continue cooking, uncovered, for another 20 minutes (30 minutes total) stirring every five to ten minutes. You will want to caramelize the onions LOW & SLOW. If they look dry at all, add a tablespoon or two of water occasionally. If the onions start to stick to your pan, add a little more olive oil.
  2. After onions have reached a nice golden brown, add the minced garlic & stir until fragrant, about 30 seconds. Add flour & onion soup mix to the onion mixture.
  3. Start boiling water in a separate pot for the noodles. To the pot of onions: whisk in chicken stock slowly to prevent the flour from clumping. Keep heat on medium & wait for the mixture to bubble.
  4. Add half & half, & let simmer while noodles cook according to directions on the package. (Mine said 10-12 minutes.) Don't let the mixture reach a rolling boil, just a light simmer. You don't want to evaporate all that yummy sauce you are making.
  5. Once the noodles are cooked & drained, add them to the sauce mixture. The sauce should be thick enough to coat a spoon. Stir the noodles in the sauce & place in a 7x11" baking dish.
  6. Sprinkle cheese over the top of the noodles. Heat cheese under the broiler in your oven until browned & bubbling. Serve & enjoy!
