French Onion Ale Soup: Deep, Rich, and Bathed in Beer and Cheese

This French Onion Ale Soup takes the classic bistro favorite and gives it a bold, malty twist with the addition of ale.

Caramelized onions simmered in beef broth and beer form a savory, slightly sweet base, topped with crusty bread and molten cheese.

It’s everything you want from comfort food: warm, gooey, toasty, and full of flavor.

Ingredients

For the Soup:

  • 4 large yellow onions, thinly sliced
  • 3 tbsp butter
  • 1 tbsp olive oil
  • 1 tsp salt
  • ½ tsp sugar (helps caramelize)
  • 2 garlic cloves, minced
  • 1 tbsp all-purpose flour
  • 12 oz ale (brown ale, amber ale, or Belgian dubbel work best)
  • 4 cups beef broth
  • 1 tbsp Worcestershire sauce
  • 1 tsp fresh thyme (or ½ tsp dried)
  • Salt and pepper to taste

For Topping:

  • Baguette slices, toasted
  • 1½ cups shredded Gruyère (or Swiss, provolone, or mozzarella)

Beer Tip: Use a malty ale for a sweet-savory base. Avoid hoppy IPAs — too bitter for the slow, caramel sweetness of the onions.

Instructions

Step 1: Caramelize the Onions

In a large Dutch oven or soup pot, melt butter with olive oil over medium-low heat.
Add onions, salt, and sugar.

Cook slowly for 35–45 minutes, stirring occasionally, until deeply golden and soft.

Don’t rush this step — the rich flavor of the soup comes from these caramelized onions.

Step 2: Add Garlic, Flour & Ale

  • Add garlic and cook 1 minute more.
  • Stir in flour and cook for another 1–2 minutes to thicken slightly.
  • Pour in the beer, scraping up any browned bits. Simmer 5 minutes.

Step 3: Add Broth & Simmer

  • Stir in beef broth, Worcestershire sauce, thyme, and pepper.
  • Bring to a simmer and cook uncovered for 20–25 minutes.
  • Taste and adjust seasoning.

Step 4: Assemble & Broil

Preheat broiler. Ladle soup into oven-safe bowls. Top each with a toasted baguette slice and a generous handful of shredded cheese.

Place under the broiler for 2–4 minutes, until bubbly and browned.

No broiler? Melt cheese with a kitchen torch or toast separately and place on top.

Serving Suggestions

  • Pair With:
    • Brown ale or Belgian dubbel
    • Crisp side salad with vinaigrette
    • Beer bread or a sharp mustard dipping sauce
  • Make It a Meal:
    • Serve with a grilled cheese, steak sandwich, or smoked sausage platter

Final Thoughts

French Onion Ale Soup is cozy, crave-worthy, and totally next-level with the depth that only a good ale can bring.

It’s the kind of soup that simmers slow and hits hard — rich, cheesy, and perfect for cold nights, beer lovers, and anyone who thinks soup should be hearty enough to count as a meal.

Cheers to comfort in a crock! 🧅🍺🧀
