Let’s get cooking!

Steps

1. In a large saucepan, heat olive oil and butter over medium-low heat. Add sliced onions, salt, and pepper, stirring occasionally for about 30 minutes until the onions are deeply caramelized.
2. Introduce minced garlic to the pan and cook for an additional 2-3 minutes until fragrant. Pour in dry white wine, thyme, and bay leaves, allowing the mixture to cook for 5 minutes until the liquid reduces by half.
3. Add water, beef stock (or vegetable stock for a vegetarian option), Worcestershire sauce (or coconut aminos), and granulated erythritol to the onions. Let the mixture simmer on low to medium heat for 30 minutes without lid, ensuring too much liquid does not evaporate.
4. Remove bay leaves and adjust seasoning with extra salt and pepper as needed. Keep the soup warm for serving or store in an airtight container in the fridge for up to 5 days or freeze for up to 3 months.
5. Preheat your oven to 375°F (190°C). Prepare the Easy Keto Dough by dividing it into 8 equal portions and pressing them into discs that fit your soup bowls.
6. Place the dough discs on a parchment-lined baking sheet, pressing fresh thyme leaves or sprigs on top of each. Bake for 15 minutes until they are lightly golden. Cool before storing them in an airtight container in the refrigerator or freezer.
7. To serve, heat the soup if it has been cooled. Ladle the hot soup into ovenproof bowls, place a thyme crouton on top, and add a slice of cheese.
8. Broil the bowls for 2-3 minutes until the cheese is melted and slightly golden. Serve the soup hot.

FAQ

• Is French Onion Soup suitable for a keto diet?
• Yes, this version of French Onion Soup is adapted to be keto-friendly by reducing the carb content. It includes a breakdown of nutritional information for each component, and you can choose to omit the crouton topper to lower the carbs further, though it may not be as filling without it.
• Why is it referred to as French Onion Soup?
• The name “French Onion Soup” originates from its popularity in France, where onions were an affordable and abundant ingredient during tough times. It became a classic dish in Parisian restaurants in the 18th century, commonly served with toast and cheese.
• Can this soup be made vegetarian or vegan?
• While traditional French Onion Soup uses beef broth for its rich flavor, you can substitute it with chicken or vegetable broth for a vegetarian or vegan option. Keep in mind, using vegetable stock may slightly increase carb content. Additionally, replace Worcestershire sauce with coconut aminos for a plant-based flavor substitute.
• Is it possible to use different types of onions in this recipe?
• Absolutely, while yellow onions are traditionally used for their mellow flavor, you can substitute them with white or red onions without significantly altering the taste of the soup.
• Can I leave out the wine in this low-carb French Onion Soup?
• Yes, you can omit the wine. Substitute it with water and add a teaspoon of balsamic or red wine vinegar to replicate the subtle flavor that the wine imparts.
• What type of cheese is best for topping this low-carb onion soup?
• Traditional French cheeses like Comte, Gruyere, or Swiss are ideal for topping French Onion Soup. However, if these are unavailable, milder cheeses like mozzarella or muenster are good alternatives. Cheddar can be used if you prefer a more pronounced cheese flavor.

Tips

• Caramelizing Onions: Ensure you cook the onions slowly over low-medium heat until they reach a rich golden brown color. This step is crucial for developing the deep, sweet flavor that characterizes French Onion Soup.
• Versatile Toppers: The thyme-flavored croutons used in this recipe are versatile and can be made in batches. They can be stored in the freezer and used to garnish other dishes like soups and stews or even as a base for breakfast sandwiches.
• Wine Substitute: If you prefer not to use wine, replace the white wine with an equal amount of water and add a teaspoon of balsamic or red wine vinegar to replicate the flavor profile without the alcohol.
• Cheese Selection: While traditional French cheeses like Gruyere or Swiss are recommended, you can use mozzarella or muenster for a milder taste. Avoid strong-flavored cheeses like cheddar, which may overpower the soup.

Equipment

• Large saucepan
• Oven-proof bowls (for broiling the cheese on top)
• Large parchment-lined baking sheet
• Broiler or oven with broil function
• proof bowls, which are specific to serving French Onion Soup.
