Smoky Ale French Onion Soup with Caramelized Onions and Beer
This French onion soup the classic with Belgian wheat ale and smoked paprika, creating deeper complexity alongside traditional caramelized onions. The beer adds malty sweetness that complements the rich beef stock, while smoked paprika introduces subtle warmth. Perfect for cold evenings when you want comfort food with a twist. Topped with crispy baguette slices and bubbling gruyere cheese, this version stands apart with its smoky, malty undertones that enhance rather than mask the sweet onion base.

Tips

Use oven-safe bowls and place them on a metal baking sheet for easy handling under the broiler.
Let the soup stand after broiling to allow the cheese to set slightly and prevent burns.

Can caramelize onions up to 2 days ahead. Complete soup base can be made 1 day ahead, add cheese and broil when serving.

Common Mistakes

FAQ
Can I make this without alcohol?
Replace beer with additional beef stock plus 1 tablespoon worcestershire sauce for depth. The malty sweetness will be missing but still delicious.
What if I don't have oven-safe bowls?
Toast cheese-topped baguette slices separately under broiler, then float on top of soup in regular bowls just before serving.
How long will leftovers keep?
Refrigerate up to 3 days. The soup base keeps well but you'll want to add fresh cheese and baguette when reheating.
