How to Make French Onion Soup with Comté Grilled Cheese
Step 1: Prepare the Onions
- Peel and slice all of the onions.
- Place a large saucepan over medium heat. Add 2 tablespoons of olive oil along with a good pinch of salt.

- Cook for an additional 5 minutes, stirring continuously until fragrant.
Step 3: Create the Broth

- Pick thyme leaves off their stems and add them to the pan; simmer for another 10 minutes.
Step 4: Adjust Seasoning
- Taste your soup and add salt as needed, being cautious since your stock might already contain salt.
Step 5: Prepare Baguette Slices
- Slice your baguette into rounds.
- Divide the soup into oven-proof bowls.
- Add a few slices of baguette to each bowl and grate over some Comté cheese.
Step 6: Grill and Serve

- Use Quality Stock: Opt for high-quality beef stock for a richer taste. Homemade stock can elevate the dish further.

Common Mistakes to Avoid
Making French Onion Soup with Comté Grilled Cheese can be simple, but there are a few common pitfalls to watch out for.
- Using low-quality onions: Always choose sweet, high-quality onions for the best flavor. Yellow or Vidalia onions are perfect for caramelizing and will enhance your soup significantly.
- Skipping the caramelization step: Properly caramelized onions are key. Take your time and cook the onions until they’re deeply golden; rushing this step can lead to a bland soup.
- Not seasoning adequately: Taste as you go! Adding salt and pepper at the right moments is crucial. Your broth might vary in saltiness, so adjust accordingly.
- Overcrowding the cheese on toast: While it’s tempting to pile on cheese, a modest amount allows for better melting and enhances texture. Aim for a balanced layer that melts without overpowering.
- Ignoring the broiling step: Broiling is essential for achieving that crispy, bubbly cheese top. Don’t skip this step if you want that classic finishing touch!
- Not using oven-proof bowls: Ensure your bowls can withstand high heat when broiling. Using non-oven-safe containers can ruin your dish and create a mess.
