French Onion Soup (simplified) Ingredients

For the Soup Base

  • Yellow onions – use sweet, large onions for natural caramelization and depth of flavor essential to French Onion Soup (simplified).
  • Butter – helps gently cook onions until golden and tender, adding richness without overpowering.
  • Garlic cloves – minced for a subtle aromatic boost that complements the onions perfectly.
  • Beef broth – provides a hearty, savory foundation; substitute with vegetable broth for a lighter vegetarian-friendly twist.
  • Dry white wine – adds bright acidity and complexity, but you can skip it if you prefer an alcohol-free option.
  • Salt and black pepper – balance the flavors and enhance the natural sweetness of the slow-cooked onions.

For Serving

  • French baguette slices – toasted to create a crunchy topping that soaks up the soup’s savory broth.
  • Gruyère cheese – melts beautifully into golden, bubbly perfection, elevating this simplified French Onion Soup to truly comforting elegance.

How to Make French Onion Soup

  1. For the Soup Base:

  2. Slice Onions: Peel and thinly slice 4 large yellow onions into even ribbons, ensuring uniform thickness so they caramelize beautifully and develop that deep, sweet flavor you crave.

  3. Melt Butter: Melt 2 tablespoons of butter in a heavy-bottomed pot over medium heat until it foams gently, creating a rich base that won’t scorch as the onions cook.

  4. Caramelize Onions: Add the sliced onions to the pot, stir to coat, then reduce heat to low and cook, stirring occasionally for 25–30 minutes until deeply golden and sweetly fragrant.

  5. Deglaze Pan: Pour in ½ cup of dry white wine, scraping up any browned bits on the pot’s bottom; cook for 2 minutes until the liquid reduces and flavors intensify.

  6. Simmer Soup: Stir in 6 cups of beef broth, bring the mixture to a gentle simmer, season with salt and pepper, and cook 10 minutes to meld all those rich, savory flavors.

For Serving:

  1. Toast Bread: Arrange baguette slices on a baking sheet, preheat the broiler, and toast for 1–2 minutes per side until each slice is lightly golden and crisp.
  2. Assemble & Broil: Ladle the hot soup into ovenproof bowls, top with toast, sprinkle generously with Gruyère, and broil 2–3 minutes until cheese is bubbly and golden brown.

Optional: Garnish with fresh thyme sprigs for a bright, herbal finish.

Expert Tips for French Onion Soup

  • Choose the right onions: Use large yellow onions for natural sweetness and ideal caramelization, key to mastering French Onion Soup.
  • Be patient caramelizing: Low and slow cooking prevents burning, transforming onions into a rich, golden base full of deep flavor.
  • Deglaze properly: Pour wine or broth while scraping the pot’s bottom to lift flavorful browned bits, enhancing every spoonful.
  • Season gradually: Add salt in stages to balance and intensify the soup’s natural sweetness without overpowering it.
  • Use sturdy bread: Toast baguette slices until crisp so they hold up under melted Gruyère without becoming soggy too fast.
  • Broil cheese carefully: Watch closely while broiling for bubbly, golden topping—too long can burn the Gruyère and spoil the rich finish.

Make Ahead Options

French Onion Soup (simplified) is perfect for meal prep! You can caramelize the onions up to 3 days in advance; just refrigerate them in an airtight container to maintain their sweet, rich flavor. For even easier meal planning, consider preparing the entire soup base (steps 2-6) upfront and storing it in the fridge for up to 3 days. When you’re ready to serve, simply reheat the soup on the stove, toast your baguette slices, and assemble with Gruyère just before broiling. This way, you’ll enjoy a comforting bowl of French Onion Soup with minimal effort, making busy weeknights feel special without sacrificing quality!

What to Serve with French Onion Soup (simplified)?

Bringing together the cozy warmth of your soup with delightful accompaniments creates a full-flavored meal experience.

  • Crusty French Baguette: Thick slices offer the perfect base for savory soup, soaking up rich broth while providing a satisfying crunch.

  • Mixed Green Salad: A light salad with vinaigrette refreshes the palate between spoonfuls of decadent soup, balancing flavors beautifully.

  • Roasted Asparagus: Tender, slightly crispy asparagus adds a touch of earthiness and a burst of color, enhancing the meal visually and nutritionally.

Pair your soup with a simple salad of mixed greens tossed in a light vinaigrette. The acidity counterbalances the richness of the onions, creating a well-rounded dining experience.

  • Savory Cheese Platter: A mix of cheeses, such as Brie and aged cheddar, offers a creamy contrast to the soup, inviting a bit of indulgence at the table.

  • Garlic Bruschetta: Toasted baguette topped with ripe tomatoes and basil makes for a refreshing appetizer, harmonizing with the flavors of your comforting bowl.

  • Red Wine: A glass of Merlot or Cabernet Sauvignon enhances the meal, echoing the broth’s rich flavors and elevating the overall experience.

How to Store and Freeze French Onion Soup

Fridge: Store leftover French Onion Soup in an airtight container in the fridge for up to 3 days. Allow it to cool completely before sealing to prevent condensation.

Freezer: Freeze the soup in individual portions in freezer-safe containers for up to 3 months. Leave a little space at the top for expansion as it freezes.

Reheating: Thaw frozen soup overnight in the fridge, then gently reheat on the stove over low heat until warm. Add a splash of broth or water if needed to adjust consistency.

Cheese Storage: If you’ve added Gruyère, consider storing it separately; cheese can become rubbery when frozen with the soup.
