How to Make Longhorn French Onion Soup
Step 1: In a large pot or Dutch oven, melt butter over medium heat. Add thinly sliced onions and cook, stirring occasionally, for about 25-30 minutes until they are golden brown and caramelized.
Step 2: Stir in minced garlic and cook for another minute. Pour dry white wine to deglaze the pot, scraping up any browned bits from the bottom.
Step 3: Sprinkle flour over the onions and stir to coat. Cook for 1-2 minutes to remove the raw flour taste.
Step 4: Slowly add beef broth while stirring to prevent lumps. Mix in Worcestershire sauce, dried thyme, bay leaves, and season with salt and pepper to taste. Bring the soup to a simmer and cook for 20-25 minutes, allowing the flavors to meld.
Step 5: While the soup simmers, preheat your oven broiler. Place 6-8 baguette slices on a baking sheet and toast until golden brown. Ladle the soup into oven-safe bowls, place a toasted baguette slice on top of each bowl, and sprinkle with shredded Gruyère or Swiss cheese. Place the bowls under the broiler for 2-3 minutes or until the cheese is melted and bubbly.
Step 7: Enjoy
Carefully remove the bowls from the oven and serve immediately. Enjoy your rich and cheesy homemade Longhorn French Onion Soup!
Longhorn French Onion Soup Recipe Tips
- Choose the Right Onions: Yellow or sweet onions work best for caramelization.
- Patience with Caramelization: Take your time caramelizing the onions.
- Deglaze Like a Pro: Use dry white wine to deglaze the pot and scrape up all those flavorful brown bits.
- Use Quality Broth: Use a rich, low-sodium beef broth or stock for the best flavor.
- Thickening Tip: Sprinkle the flour evenly over the onions to avoid clumps.
- Cheese Choice: Gruyère is traditional, but Swiss, mozzarella, or a blend of cheeses can also work for the topping.
- Sturdy Bread: Use crusty baguette slices to avoid getting too soggy under the cheese.
- Seasoning Adjustments: Taste the soup before serving and adjust the salt and pepper as needed.
- Broiler Safety: Use oven-safe bowls for broiling, and keep a close eye to prevent the cheese from burning.
- Customize Garnishes: Add fresh thyme sprigs, a drizzle of balsamic glaze, or a pinch of grated Parmesan for a unique touch.
Storing
- Storing: Allow the soup to cool completely before transferring it to an airtight container. Store in the refrigerator for 3-4 days for the best flavor and freshness.
- Freezing: Freeze the soup (without the bread and cheese topping) in a freezer-safe container, leaving space for expansion. It can be stored in the freezer for up to 3 months.
- Reheating: Thaw frozen soup in the refrigerator overnight before reheating. Warm the soup on the stovetop over medium heat or in the microwave, then add the toasted bread and cheese topping before serving.
What To Serve With Longhorn French Onion Soup Recipe
When serving Longhorn French Onion Soup, you can pair it with a variety of sides that complement its rich, savory flavors. A classic choice is crusty bread or toasted baguette slices, perfect for soaking up the flavorful broth. For a lighter balance, serve the soup alongside a fresh mixed green salad with a tangy vinaigrette to cut through the richness. If you’re looking for something heartier, a grilled cheese sandwich or roasted vegetables add a comforting touch to the meal. For an indulgent side, try a creamy potato gratin or pair it with a juicy steak or roast beef for a more substantial, satisfying dinner. These accompaniments will elevate the French onion soup and create a delicious, well-rounded meal.
Longhorn French Onion Soup Recipe Faqs
Can I use a different type of cheese? While Gruyère and Swiss are traditional, you can experiment with other cheeses like provolone, mozzarella, or cheddar.
How do I make the soup less salty? To reduce the saltiness, use low-sodium beef broth and Worcestershire sauce. You can also adjust the seasoning by adding a pinch of sugar to balance the flavor.
Can I make the soup vegetarian? Yes! Substitute the beef broth with vegetable broth for a vegetarian version. The flavors will still be rich and satisfying.
Can I prepare the bread and cheese topping in advance? You can prepare the bread slices ahead of time by toasting them with butter and garlic. Store them in an airtight container and add the cheese when you’re ready to broil them over the soup.
How can I make the onions caramelize faster? Caramelizing onions can take time, but if you’re in a hurry, cook them over medium-high heat for a shorter period, stirring frequently. Just be careful not to burn them!
