Raw ingredients for making classic French onion soup including yellow onions, butter, olive oil, sugar, salt, pepper, beef broth, red wine, balsamic vinegar, bay leaf, baguette, Gruyere cheese and thyme sprigs
  • 3 pounds Yellow Onions, thinly sliced: This is the heart and soul of our classic French onion soup. Don’t skimp on the onions! Yellow onions are the way to go, they caramelize beautifully and provide that signature sweet flavor.
  • 4 tablespoons unsalted Butter: Adds richness and helps the onions caramelize perfectly for our classic French onion soup.
  • 2 tablespoons Olive Oil: Prevents the butter from burning and adds another layer of flavor.
  • 1 teaspoon Sugar: This is our game-changer for classic French onion soup. It helps the onions caramelize faster and brings out their natural sweetness.
  • 1 teaspoon Kosher Salt: Seasoning is key!
  • ½ teaspoon Black Pepper: Adds a little spice!
  • 8 cups Beef Broth: This is where that deep, savory flavor comes from. Splurge on good quality beef broth for this classic French onion soup – trust me, you’ll taste the difference. You can find the best ingredients for this classic French onion soup at your local butcher or specialty grocery store.
  • 1 cup Dry Red Wine (such as Merlot or Cabernet Sauvignon): Adds depth and complexity. If you don’t have red wine on hand, you can substitute with beef broth.
  • 2 tablespoons Balsamic Vinegar: Adds a touch of tanginess that balances the sweetness.
  • 1 Bay Leaf: Infuses the broth with a subtle, aromatic flavor.
  • 1 French Baguette, sliced into ½-inch thick rounds: We need that crusty bread for topping.
  • 8 ounces Gruyere Cheese, shredded: The king of cheese for classic French onion soup. It melts beautifully and has a nutty, slightly sweet flavor that complements the soup perfectly.
  • Fresh Thyme Sprigs (optional, for garnish): Adds a touch of elegance.

Here’s the classic French onion soup game-changer that will blow your mind: balsamic vinegar! It’s my secret weapon for adding that extra zing that takes this soup from good to freakin’ phenomenal. Trust me on this one, amigas! It’s also a budget-friendly alternative that still delivers!

STEP-BY-STEP INSTRUCTIONS:

Alright, flavor adventurers, let’s get down to business! These steps are your roadmap to classic French onion soup glory. Don’t stress – your soup is going to be incredible! I have so much faith in you!

  1. Caramelize the Onions (45-60 minutes): In a large, heavy-bottomed pot or Dutch oven, melt the butter and olive oil over medium heat. Add the sliced onions, sugar, salt, and pepper. Stir to coat the onions evenly. Reduce the heat to low and cook, stirring occasionally, until the onions are deeply caramelized and a rich, golden-brown color. This will take about 45-60 minutes. Be patient! This is the most important step for a deeply-flavored classic French onion soup. Pro tip for classic French onion soup perfection: don’t rush the caramelization process. Low and slow is the key. Your classic French onion soup should look like it came straight out of a food magazine!
  2. Deglaze the Pot (5 minutes): Once the onions are caramelized, pour in the red wine and balsamic vinegar. Bring to a simmer and scrape the bottom of the pot to loosen any browned bits. Cook for 5 minutes, allowing the alcohol to evaporate. This is where your classic French onion soup transforms into pure magic.
  3. Add Broth and Simmer (30 minutes): Pour in the beef broth and add the bay leaf. Bring to a simmer, then reduce the heat to low and cover. Simmer for at least 30 minutes, or up to an hour, to allow the flavors to meld. In my kitchen, this classic French onion soup takes exactly 45 minutes to reach peak flavor perfection.
  4. Prepare the Bread (10 minutes): While the soup is simmering, preheat your oven’s broiler. Arrange the baguette slices on a baking sheet and broil for 2-3 minutes per side, or until lightly toasted. Keep a close eye on them – they can burn quickly!
  5. Assemble the Soup (5 minutes): Remove the bay leaf from the soup. Ladle the soup into oven-safe bowls or crocks. Top each bowl with a few toasted baguette slices and a generous amount of shredded Gruyere cheese. Don’t skimp on the cheese! This is where most people mess up their classic French onion soup – but not you!
  6. Broil Until Golden (2-3 minutes): Place the bowls under the broiler and broil for 2-3 minutes, or until the cheese is melted, bubbly, and golden brown. Watch closely to prevent burning! Your classic French onion soup should smell absolutely divine at this point!
  7. Garnish and Serve (Immediately): Remove the bowls from the oven and garnish with fresh thyme sprigs (optional). Serve immediately and prepare for the flavor explosion! While your classic French onion soup is working its magic, grab your camera – this is Instagram gold!

Here’s a technique secret: add a splash of sherry vinegar at the end for an extra layer of complexity to your classic French onion soup. You won’t regret it!

Q: What’s the secret to getting perfectly caramelized onions for my classic French onion soup?

A: Patience, amiga! Low and slow is the key. Don’t rush the caramelization process. Stir the onions occasionally to prevent them from burning, and add a little water if they start to stick to the bottom of the pot. I like to deglaze as they go for even caramelization!
