What’s So Special About Costco French Onion Soup?

These little bowls of goodness are pre-made but pack all the flavors you’d expect from a restaurant-quality dish. The rich, savory broth is loaded with caramelized onions and topped with melted cheese—just like you’d get at a fancy bistro.
The kicker? All the hard work (like chopping onions or making a broth from scratch) is already done for you. It’s literally heat, serve, and enjoy. Perfect for busy weeknights, lazy weekends, or when you’re just in the mood for something warm and comforting without the hassle.
Why Is French Onion Soup So Popular?
French onion soup has been around forever (well, since the 18th century, but who’s counting?). Its appeal lies in its simple yet flavorful ingredients:
- Caramelized onions: Sweet, savory, and oh-so-tender.
- Beef broth: Rich and hearty, it’s the backbone of the soup.
- Cheesy topping: Gruyere or Swiss cheese, bubbling and golden, brings it all together.
- Bread: Usually a baguette slice, toasted and placed on top to soak up all that goodness.
Costco’s version absolutely takes all of these elements. They seem to have bottled the magic of a classic French recipe and made it accessible for everyday life.
How to Cook Costco French Onion Soup
Let’s be real—one of the best things about Costco French onion soup is how easy it is to prepare. No slicing, no dicing, no hours of simmering. Here’s how you can get it ready:
- Oven Method
If you want that perfectly melted, golden-brown cheese, this is the way to go.
- Preheat your oven to 400°F.
- Place the frozen soup in a heat-safe bowl or ramekin.
- Pop it into the oven for about 40 minutes.
- When it’s done, the cheese will be bubbly, and the soup will smell like heaven.
2. Microwave Method
In a hurry? The microwave has your back.
- Place the frozen soup in a microwave-safe bowl.
- Heat on high for about 5 minutes, stir, then heat for another 3-4 minutes.
- It won’t give you that crispy cheese layer, but it’s still darn delicious.
Pro Tips for Serving Costco French Onion Soup
Now, if you’re anything like me, you’ll want to make this soup feel a little extra. Even though Costco’s version is fantastic on its own, you can jazz it up with these simple ideas:
- Upgrade Your Bread
The soup already has a cheesy bread layer, but adding a fresh, toasty slice of baguette on the side? Game changer. Slice it thin, toast it, and maybe even rub a little garlic on top for that bistro vibe.
- Add Fresh Herbs
A sprinkle of fresh thyme or parsley on top can brighten up the flavors and make it look fancy. (Bonus: it smells amazing.)
- Serve with a Side Salad
Pair your soup with a light salad for a full meal. A simple arugula or mixed greens salad with vinaigrette balances the richness of the soup perfectly.
- Pair with Wine
French onion soup and a glass of wine? Yes, please. A dry white wine like Sauvignon Blanc or a light red like Pinot Noir works beautifully.

Pro tip: This soup is seasonal, so it’s more commonly stocked during the fall and winter months. If you’re having trouble finding it, you can ask your local Costco when they’ll restock.

Can You Make It Even Better?
Sure, Costco’s version is pretty darn close to perfect, but if you’re feeling ambitious, you can give it a personal twist.
- Extra Cheese: Add more Gruyere, Parmesan, or even mozzarella on top. Because there’s no such thing as too much cheese, right?
- Spice It Up: A pinch of cayenne or a drizzle of hot sauce can give it a little kick.
