French Onion Soup. Crocks filled with sweet caramelized onion, rich, sherry-kissed stock, topped with a crusty baguette and reams of melty gruyere. This is one of life’s true pleasures. But to make it — and make it well, you need beef stock, made from scratch right? The kind of stock that comes from slow-roasting beef bones and simmering for days. While it’s not difficult, it requires time that most of us don’t have. But it doesn’t have to be that way. Not anymore. In a kind of serendipity, I’ve discovered Kettle and Fire real beef bone broth.
It’s made from grass-fed beef bones, and is slow simmered for more than 20 hours. This broth is paleo friendly and gluten-free, and it’s made from the same ingredients you would use in your own kitchen, if you had the time (check out the video, above). And it’s exactly what I needed for this French Onion Soup.
While French Onion Soup may seem like an indulgence with a cheese-laden crouton crowning the bowl, you may not know that the bone broth in this soup is incredibly nutritious.
Real bone broth is made from parts of the animal we typically throw away (bones, marrow, joints) and it’s slow-simmered for 12-24 hours. Animal bones contain collagen and the long cooking process breaks down the collagen into a more digestible form — gelatin. It’s the gelatin that contains many amino acids like glutamine which helps repair your gut lining, detox your liver, and reduce joint inflammation.
Trouble is, you don’t get those benefits with the canned beef broth in the grocery store. I checked and one of the more popular brands – doesn’t even contain beef bones… much less carrots, onions, etc. and it has way to much sodium. The difference is huge!!!

French onion soup starts with onions, thinly sliced and simmered in a heavy pot until they give up their liquid and start to turn a golden color. After they’ve caramelized, I add dry white wine 🙂 and simmer until nearly all the liquid has evaporated. Then come the bay leaves, thyme and the broth.
The soup simmers for another 15 or so minutes and while it’s cooking, I grate the gruyere and toast the sliced baguette rounds. A little dry sherry added to each of the bowls, gives the soup its familiar flavor.
Top with crispy baguette slices and a generous sprinkle of shredded gruyere – then it’s into the oven for the last few minutes. This has got to be one of my all time favorite soups. I love the part crispy, part gooey, and part soup-laden bread, the stretchy cheese, tender onions and savory broth. If you’ve never made it yourself, what are you waiting for?

Homemade French Onion Soup
- 3 tablespoon unsalted butter
- 3 large sweet onions about 2 pounds peeled and thinly sliced
- 2 teaspoons vegetable or canola oil
- 3/4 teaspoon kosher salt
- 1/4 teaspoon black pepper
- 1 cup white wine
- 4 cups Kettle and Fire Beef Bone Broth
- 8 sprigs thyme
- 2 bay leaves
- 1 baguette sliced into 1/2" rounds - depending on the circumference of the bread use 1 or 2 slices per serving
- 1 garlic clove
- 2 teaspoons sherry
- 4 ounces grated gruyere cheese
In a large dutch oven over medium heat, melt the butter and oil together. Add the sliced onions and cook for 15 minutes until softened, stirring occasionally. Stir in the salt and pepper. Place the lid askew on the pot and continue to cook for an additional 45-50 minutes, stirring occasionally until they onions are caramelized. Moderate the heat if the onions are browning too quickly.
Add the wine and simmer until most of the liquid has evaporated, about 10-15 minutes. Tie the thyme with a kitchen string into a tight bundle. Add the thyme, bay leaves and broth. Simmer for 15 minutes.
Meanwhile preheat the oven to 400°. Slice the baguette into rounds and place on a baking sheet. Bake the bread for about 4-5 minutes, then flip the slices and cook for an additional 3-4 minutes, until toasts are crisp and lightly browned. Turn up the oven to broil.
Remove the thyme and bay leaves and discard. Add half a teaspoon of sherry each to 4 ovenproof crocks or bowls. Ladle the soup into the bowls and place on a baking sheet. Rest 1-2 toasts on top of each bowl of soup and sprinkle each with the gruyere.
Broil for 2-5 minutes until the cheese is melty and the edges of the bread are crisp. Serve.
