French Onion Soup You’ll Love for Holiday

French onion soup is one of those comforting, soul-warming dishes I can’t resist making when the days get a little cooler. The rich, slow-cooked onions melt into the savory broth, topped with golden, bubbly cheese and crisp bread that soaks up all that flavor.

What I enjoy most about this recipe is that it’s easy enough for a weeknight dinner but also elegant enough for a special meal with friends.

This classic soup pairs beautifully with a crisp green salad drizzled with vinaigrette or a fresh Caesar salad. It can also be enjoyed alongside a roasted chicken or seared steak for a heartier meal. For something a bit lighter, serve it with quiche Lorraine or a simple cheese board featuring brie, camembert, and some fresh fruit.

French onion soup also pairs wonderfully with drinks that highlight its rich, savory flavor. You can try dry red wine like Pinot Noir or Cabernet Sauvignon. For a non-alcoholic option, try sparkling apple cider or a cold iced tea with lemon.

And if you want to end the meal on a sweet note, follow with a small serving of crème brûlée or a scoop of vanilla gelato to round out the classic French experience.

Ingredients

• 4 large yellow onions, thinly sliced
• 3 tbsp unsalted butter
• 1 tbsp olive oil

• Salt and pepper to taste
• 1 baguette, sliced
• 1 1/2 cups shredded Gruyère or Swiss cheese

Instructions

Notes

• Caramelizing onions low and slow is the key to deep flavor — don’t rush it.
• You can substitute chicken or vegetable broth, but beef broth gives the most authentic taste.
• Gruyère melts best, but mozzarella or Swiss also work.
• If you don’t have broiler-safe bowls, melt the cheese on the bread separately and place it on top of the soup.
