Variations

This recipe is flexible, allowing you to customize it to suit your tastes or what you have on hand. Here are some fun variations:

  • Swap the broth: Use vegetable broth instead of beef broth for a lighter version that still packs flavor.
  • Add some greens: Toss in some fresh spinach or kale towards the end of cooking for added nutrients and color.

  • Cheese alternatives: If you prefer different cheeses, feel free to experiment with Swiss or mozzarella for unique flavors.

How to Make French Onion Soup Recipe

Step 1: Cook Onions

Start by bringing your large Dutch Oven to medium-high heat. Add the butter and olive oil together until melted. This mixture will help sauté your shallots and onions beautifully. Cook them on medium heat until they soften—about 15 minutes. Then increase the heat slightly and let them caramelize for another 30 minutes. Stir frequently; we want those sweet flavors to develop nicely.

Step 2: Deglaze Pan

Once your onions look jam-like and fragrant, it’s time to deglaze the pan! Pour in the white grape juice while scraping up any tasty bits stuck at the bottom. This step adds depth to your soup’s flavor profile! Mix in the minced garlic, stirring it through so that its aroma fills your kitchen.

Step 3: Finish Soup

Now add the flour into your pot and stir well—this will help thicken your soup later on. Gradually pour in the broth, about 1/4 cup at a time while stirring constantly. Incorporate all those savory components: Beef Broth Concentrate, Worcestershire sauce, balsamic vinegar, soy sauce, lemon zest, pepper, salt, and your herb bundle. Cover it up and let everything simmer for 20-30 minutes so those flavors meld beautifully!

Step 4: Baguettes

While your soup simmers away happily, preheat your oven to 450°F (230°C). Place those sliced baguettes on a baking sheet and brush them lightly with olive oil. Pop them into the oven until they turn golden brown—keep an eye on them; it won’t take long!

Step 5: Taste + Adjust

Don’t forget to give your soup a taste! Add more salt if needed to adjust for seasoning—it should be just right before serving.

Step 6: Broil

Ladle your sumptuous soup into bowls—either four small ones or two big ones if you’re extra hungry! Place two baguette slices atop each bowl then generously cover with shredded gruyere and parmesan cheese. Broil them until bubbly and golden—you’ll want to watch closely here!

Step 7: Serve

Once out of the oven, allow them to cool slightly before serving. Garnish with freshly chopped parsley and cracked black pepper—and then dig into this delightful dish! Your heart will thank you!

  • Use Quality Onions: Vidalia onions are sweet and reduce beautifully during cooking, enhancing the overall flavor of your soup. Their natural sweetness will shine through when caramelized.

  • Take Your Time with Caramelization: Don’t rush the cooking process! Allowing the onions to slowly caramelize brings out their full flavor profile. Patience is key here—your reward will be a rich, deep color and taste.

  • Deglaze Properly: Scraping up those flavorful brown bits from the bottom of the pan is essential. This adds depth to your soup; using a splash of white grape juice helps lift these bits and infuses extra flavor.

  • Adjust Seasoning Gradually: Taste as you go! Adding salt, pepper, or acidity at different stages allows you to find that perfect balance without overpowering the dish.

  • Broil Until Golden: When melting the cheese on top, keep an eye on it while broiling. You want it bubbly and golden but not burnt. This step creates that delicious crust that will have everyone reaching for more!

Garnishes

  • Fresh Herbs: A sprinkle of freshly chopped parsley or chives adds a pop of color and freshness that contrasts beautifully with the rich soup.

Side Dishes

  • Mixed Green Salad: A light salad with seasonal greens dressed in a simple vinaigrette offers a refreshing contrast to the hearty soup.
  • Roasted Vegetables: Roasted carrots, Brussels sprouts, or squash add warmth and depth while complementing the flavors of your French Onion Soup.
  • Cheesy Garlic Bread: Similar to baguette slices but with an added kick of garlic and cheese, this side pairs perfectly for dipping into your bowl.
