Slow Cooker French Onion Soup is a classic comfort food, ideal for those days when you want a warm, rich, and flavorful meal with minimal effort. The slow cooker does most of the work, caramelizing the onions slowly to draw out their natural sweetness and melding the flavors together perfectly. Here’s how to make it.
Ingredients:
- 5-6 large yellow onions, thinly sliced
- 3 tablespoons unsalted butter, melted
- 1 tablespoon olive oil
- 2 cloves garlic, minced
- 8 cups beef broth (or a mix of beef and chicken broth for a lighter version)
- 1/2 cup dry white wine (optional)
- 2 bay leaves
- 1 teaspoon dried thyme (or 2 teaspoons fresh thyme leaves)
- Salt and freshly ground black pepper, to taste
- 1 baguette, sliced and toasted
- 1 1/2 cups grated Gruyère cheese (or Swiss cheese as a substitute)
- 1/2 cup grated Parmesan cheese
