How to Make One Pot French Onion Soup

Inspired by classic French Onion Soup, this one pot pasta recipe begins with caramelized onions. While it may take a while to achieve that deep golden brown colour, the amazing savoury sweetness that it’s going to add to the pasta makes everything worth it so don’t rush the process. Low and slow will get the job done!

How to caramelise onions.

To caramelise the onions, thinly slice yellow onions and drop them into an oiled dutch oven or high walled pot. Place the skillet over medium heat and sprinkle with salt. Allow the onions to do their thing. They don’t need much intervention here. You don’t want the onions to burn so if at any point they appear dry or beginning to burn, just add in a splash of water and continue cooking. This process will take about 20 minutes and the onions will turn to a beautiful golden brown.

Once the onions have cooked down and become deeply caramelized, it is time to deglaze the pan. Deglaze the pan with a little white wine and use a wooden spoon to pull up any brown bits on the bottom of the pot.

Now we can add in the beef stock and thyme, increase the heat to high and bring the mixture to a boil. Once boil has been reached pour in the pasta, reduce to simmer, and cover the pot and allow it to simmer away until pasta is nice and soft.

While pasta is simmering you can prepare the toppings. Grate some gruyere cheese and toast some bread crumbs. When pasta is soft add in a 1/2 cup of cream and season to taste with thyme, salt, and black pepper. When serving the pasta top it with toasted bread crumbs and shredded gruyere.
