Ingredients: High Protein French Onion Chicken Soup

Here’s what you’ll need to create this delicious and nourishing soup:
- * 4 cups sweet onion, thinly sliced (from 4 medium/large)
- * 2 cups shallot, thinly sliced (from about 4)
- * 1 teaspoon kosher salt
- * 1 2/3 tablespoons extra virgin olive oil
- * 2 tablespoons all-purpose flour, or gluten-free flour
- * ¼ cup light white wine, such as Pinot Grigio (see note below)
- * ¼ cup sherry vinegar
- * 4 fresh thyme sprigs
- * 2 dried bay leaves
- * 8 cups chicken bone broth, I used Swanson Chicken Bone Broth
- * 1 pound boneless skinless chicken thighs, or chicken breast
- 6 slices baguette, or sourdough bread, 1/2 ounces each toasted
- * 12 thin slices Gruyere cheese, or Swiss cheese, 6 ounces total
Step-by-Step Instructions
- 1. Caramelize the Onions & Shallots: In a large, heavy-bottomed pot or Dutch oven, heat the olive oil over medium heat. Add the sliced sweet onions and shallots, along with the kosher salt. Cook, stirring frequently, for 45-60 minutes, or until the onions are deeply caramelized and a rich, golden brown color. Chef Tip: Patience is key here! Don’t rush the caramelization process, as this is where the majority of the flavor comes from.
- 2. Deglaze & Build Flavor: Once the onions are caramelized, sprinkle in the flour and cook for 1-2 minutes, stirring constantly. This will help thicken the soup. Slowly pour in the white wine and sherry vinegar, scraping up any browned bits from the bottom of the pot.
- 3. Add Aromatics & Broth: Add the thyme sprigs and bay leaves to the pot. Pour in the chicken bone broth and bring to a simmer.
- 4. Cook the Chicken: Add the chicken thighs (or breast) to the simmering broth. Cook for 15-20 minutes, or until the chicken is cooked through and easily shreds. Remove the chicken from the pot and shred it with two forks.
- 5. Combine & Simmer: Return the shredded chicken to the pot. Remove the thyme sprigs and bay leaves. Taste and adjust seasoning as needed. Simmer for another 10-15 minutes to allow the flavors to meld.
- 6. Broil the Soup: Preheat your broiler. Ladle the soup into oven-safe bowls. Top each bowl with a slice of toasted baguette and 2 slices of Gruyere (or Swiss) cheese. Place the bowls under the broiler for 2-3 minutes, or until the cheese is melted and bubbly. Chef Tip: Watch carefully under the broiler to prevent burning!
- 7. Serve Immediately: Let cool slightly before serving and enjoying this comforting High Protein French Onion Chicken Soup.

Why This Recipe Works & Expert Tips
This High Protein French Onion Chicken Soup works because it builds upon the foundation of a classic French Onion Soup – the deeply caramelized onions – and adds a substantial protein boost with the chicken. Using chicken bone broth not only enhances the flavor but also provides additional collagen and nutrients.
The key to a truly exceptional soup is the slow caramelization of the onions. This process develops their natural sugars, creating a rich, sweet, and savory base. Don’t be tempted to speed it up by increasing the heat; low and slow is the way to go.
This is truly easy comfort food for family dinners that everyone will enjoy. For a richer flavor, consider using a combination of sweet onions (like Vidalia) and yellow onions.
Storage, Freezing, and Reheating Tips
Leftover healthy chicken soup can be stored in an airtight container in the refrigerator for up to 3 days. For longer storage, you can freeze the soup (without the bread and cheese) for up to 2 months.
To reheat, thaw the soup completely if frozen. Heat gently on the stovetop over medium heat, stirring occasionally, until warmed through. If you want to add the bread and cheese, do so after the soup is heated and broil as directed in the recipe.
Freezing may slightly alter the texture of the onions, but the flavor will remain delicious.
People Also Ask: High Protein French Onion Chicken Soup

How do you make high protein French onion chicken soup?
This High Protein French Onion Chicken Soup starts with slowly caramelizing sweet onions and shallots to create a rich, flavorful base. Chicken bone broth is added for depth and nutrients, along with chicken thighs (or breast) for a protein boost. The soup is simmered until the chicken is tender, then topped with toasted baguette slices and melted Gruyere cheese before being broiled to golden perfection.
It’s a comforting and satisfying meal that’s surprisingly easy to make, offering a healthier twist on a classic.
What makes this soup high in protein?
The addition of 1 pound of chicken to the traditional French Onion Soup recipe is what significantly increases the protein content. Using chicken bone broth also contributes a small amount of protein, but the chicken itself is the star when it comes to boosting the nutritional value.
This makes it a more substantial and filling meal, perfect for those looking to increase their protein intake. This protein soup is a great alternative to traditional soups that may be lacking in this essential nutrient.
Is this a traditional French onion soup recipe?
While inspired by the classic French onion soup, this recipe incorporates a key addition – chicken! Traditional French Onion Soup typically doesn’t include meat. We’ve also opted for chicken bone broth for added health benefits, which isn’t always used in traditional recipes.
However, the core technique of slowly caramelizing onions and using a rich broth remains true to the original. It’s a delicious adaptation that honors the spirit of the classic while offering a modern, protein-packed twist.
Can I use different cheeses?
Absolutely! While Gruyere is the traditional cheese used in French Onion Soup, you can certainly substitute it with other cheeses that melt well and have a similar nutty flavor. Swiss cheese is a great alternative, as is provolone or even a blend of mozzarella and Parmesan. Experiment to find your favorite combination! Just ensure the cheese is thinly sliced to melt evenly under the broiler.
Conclusion: High Protein French Onion Chicken Soup
I hope you’ll give this High Protein French Onion Chicken Soup a try! It’s a wonderful way to enjoy a classic flavor with a healthy and satisfying boost. Don’t be intimidated by the onion caramelization – it’s a labor of love that truly pays off.
