• 1 tablespoon Worcestershire sauce – Adds a unique umami depth to the overall profile of the Costco onion soup.
• 1 teaspoon thyme – Fresh or dried thyme complements the savory flavors of the soup; use a bit more if you love it!
• Salt and pepper to taste – Season generously to bring out the flavors of all the ingredients.
• 1 cup grated Gruyère cheese – Gruyère is the classic choice for its meltability and nutty flavor, essential for that cheesy crust on top.
• 1 cup crusty bread, toasted and cut into cubes – A baguette or sourdough works great; toasting adds texture and prevents sogginess.

3. Step-by-Step Instructions

Step 1: Caramelize the Onions

Begin by heating the butter in a large pot or Dutch oven over medium heat. Once melted, add the sliced onions. Stir occasionally for about 30-45 minutes, or until they are golden brown and deeply caramelized. The key to great hearty frozen onion soup is patient caramelization; don’t rush this process! The onions should be sweet and almost jam-like in consistency. If they start to burn, reduce the heat and add a splash of water to deglaze the pot.

Step 2: Prepare the Broth

Once your onions are perfectly caramelized, add the beef broth into the pot. Stir in the Worcestershire sauce, thyme, salt, and pepper. Bring the mixture to a gentle boil, then lower the heat and let it simmer for at least 20-30 minutes, or even longer if you have the time. The longer simmering time allows the flavors to meld together beautifully, developing the characteristic depth you’d expect from a delicious bowl of frozen French onion soup. Consider adding a bay leaf for extra flavor while simmering, remembering to remove it before serving.

Step 3: Create the Soup Base

After simmering, taste and adjust the seasoning as needed. Take the pot off the heat. At this stage, you can either serve immediately or let the soup cool down completely before freezing. For convenience, transfer the soup into freezer-safe containers, leaving some headspace to allow for expansion. Label each container with the date and contents if you decide to make a batch for later! This ensures you always have a comforting bowl of Costco onion soup-inspired goodness ready to go.

Step 4: Serve with a Cheesy Twist

To enjoy, preheat your oven to broil. If frozen, thaw the soup overnight in the refrigerator. Ladle soup into oven-safe bowls or ramekins, top each with toasted bread cubes (or a slice of baguette), and sprinkle generously with Gruyère cheese. Place the bowls under the broiler for a few minutes, keeping a close eye on them, until the cheese is bubbly, melted, and golden brown. Serve your hearty frozen onion soup hot, garnished with fresh thyme, if desired. Pair it with more toasted bread or a fresh green salad — a perfect combination to complement the rich flavors. This is a great answer to the question of what to eat with French onion soup.

4. Storage Tips

To ensure the freshness of your frozen French onion soup, store in airtight containers in the freezer for up to 3 months. For optimal quality, use within this timeframe. Thaw overnight in the refrigerator before reheating. When reheating, you can do so on the stovetop over medium heat, stirring occasionally, or in the microwave. This allows you to enjoy the comforting flavors at a moment’s notice! Always ensure the soup is heated thoroughly before serving.

5. Serving Suggestions

This recipe pairs beautifully with a side of crusty baguette, perfect for soaking up all that delicious broth. It also complements a light, mixed greens salad drizzled with balsamic vinaigrette to cut through the richness. For a heartier meal, serve it alongside a grilled cheese sandwich made with sharp cheddar or provolone, offering a comforting contrast to the savory soup. Or, for a fusion twist, consider serving it alongside our Sushi Siam’s Flavorful Fusion for an unexpected culinary adventure!

6. Frequently Asked Questions

What is Costco French onion soup?

Costco French onion soup refers to the convenient, ready-made soups found at Costco, often praised for their robust flavors and substantial portions. These pre-made options have made it a popular choice for busy individuals seeking a quick and easy warm meal during colder months. Many people try to replicate its taste at home.

How can I enhance the flavor of my onion soup?

For an enhanced flavor in your homemade Costco French onion soup alternative, consider adding a splash of dry white wine or sherry while caramelizing the onions.
