How to Make Slow Cooker French Onion Soup
Making Slow Cooker French Onion Soup is like starting a cozy culinary journey, and I promise it’s worth every moment. To kick things off, grab those 6 lbs of onions and slice them up. Yes, it sounds like a mountain of onions, but trust me, they’ll shrink down to a sweet, caramelized goodness that’s the heart of this soup.
In a large skillet, melt 1/4 cup of butter over medium heat and start sautéing your onions. You want them to become soft, translucent, and take on a lovely caramel color. Depending on your skillet size, you may need to do this in three batches. It might feel like a lot of work, but the aroma will have you dreaming of French bistros.
Once your onions are nicely sautéed, it’s time to transfer them to your slow cooker. Here’s a little secret: deglaze that skillet with some of the 14 cups of beef stock, scraping up all those flavorful bits stuck to the bottom. This is where the magic really begins. Pour this deglazed goodness into the slow cooker along with the rest of the beef stock.
Add in 1/2 teaspoon of Worcestershire sauce, 1 bay leaf, and 1/4 teaspoon of thyme. Season with salt and pepper to taste, then cover and set your slow cooker to High for about 4 hours or Low for 6-8 hours. This is the perfect time to kick back and let the magic happen in your kitchen.
When the time’s up, and your home is filled with the warm, inviting scent of French onion soup, it’s time to serve. Don’t forget to remove the bay leaf before you dig in. For that classic finish, take 2 slices of toasted crusty bread and place them in your soup bowls.
Ladle the steaming soup over the bread, sprinkle with 2 tablespoons of grated Parmesan cheese, and then top with 1/4 cup of shredded Gruyère cheese. For the grand finale, pop those bowls under the broiler for a few minutes until the cheese is all melty and bubbly. The contrast of the hot, savory soup with the gooey cheese is pure heaven.
Who needs a fancy restaurant when you can have this at home? Enjoy the fruits of your labor, and remember, a little cheese never hurt anyone.
