Ingredients

• 4 large onions, sliced
• 2 tablespoons butter
• 1 teaspoon sugar
• 2 quarts beef broth, no sodium added

• 2 sprigs fresh thyme
• 1½ teaspoons salt
• Pepper to taste
• Sliced bread of choice (or croutons)
• 8 ounces Gruyere cheese, sliced (can substitute with Swiss)

Preparation Method

To kick off your slow cooker French onion soup, gather your ingredients and prepare your slow cooker. You’ll want to take a large, sturdy onion and slice it into thin rings. The way you slice the onion is crucial because you want it to caramelize evenly. Opt for larger onions as they are generally sweeter and offer a more robust flavor.

Next, move on to the butter. In a skillet over medium heat, melt the butter until it's bubbly and slightly foaming. This will create a beautiful base for the onions. Then, add your sliced onions to the pot, mixing them well so they're all coated in that rich, melting butter. The magic ingredient here is sugar. By adding just a teaspoon, you will encourage the caramelization process to happen more quickly and beautifully.

Cover the slow cooker and set it to high. Allow the onions to cook for about seven hours, stirring occasionally if time allows. You will know your onions are ready when they have turned profound shades of golden-brown, releasing all their sweet, savory flavor into the air.

Once your onions have caramelized beautifully, it’s time to add in the rest of the ingredients. Carefully pour in your beef broth, making sure to scrape up any flavorful bits stuck to the side of the slow cooker. Follow that with the sherry—a key ingredient that adds depth and enhances the entire flavor profile. Toss in the thyme sprigs and stir, allowing all those delicious elements to mingle together.

Season the soup with salt and add pepper. If you prefer a bit of spice, feel free to add red pepper flakes or a dash of hot sauce to suit your taste.

Now, cover the slow cooker again and continue to let it work its magic for one more hour. As the flavors meld together, your home will envelop in a fragrant aroma that’s sure to make everyone’s mouth water in anticipation.

When the hour of waiting is over and the soup smells divine, it’s time to think about serving. Using ladles, carefully scoop out the warm soup into ovenproof mugs or bowls. The classic French way calls for a hearty slice of bread atop each serving, so select your favorite crusty loaf and layer it generously across the mug’s surface.

Now comes the golden finale—topping off your soup with slices of Gruyere cheese. This cheese is a classic choice, as it melts beautifully and creates that iconic stretchy effect. If you can’t find Gruyere, Swiss cheese is a splendid substitute, providing that same luxurious melt.

Once you’ve made all your preparations, pop the mugs under the broiler in your oven for just a few minutes. Keep a close eye on them—you want the cheese to bubble and brown but not burn to the smoking point. This final touch imparts a restaurant-quality finish and elevates your soup to the next level.

Tips and Conclusion

If you truly want to impress your guests, let the soup cook for an additional fifteen minutes with the cheese on top in the broiler. It will melt into a gooey delight that everyone will swoon over when they take their first spoonful.
