What Is French Onion Soup?
French onion soup is a classic soup made with thinly sliced onions that are slowly caramelized until deeply golden and sweet. The onions are simmered with broth, wine, and seasonings, then traditionally topped with bread and melted cheese.
This version uses Roots Farm Fresh Sweet Potato Toasts instead of traditional bread for a sweet and savory topping that pairs beautifully with the caramelized onions and Gruyere cheese.

Ingredients
French Onion Soup
• 8 Roots Farm Fresh Sweet Potato Toasts
• 3 large yellow onions, thinly sliced
• 4 cups vegetable or beef stock
• 1 cup Gruyere cheese, freshly grated
• ½ cup dry white wine
• 1 tablespoon all-purpose flour
• 3 tablespoons butter
• Splash of dry sherry
• Sea salt and black pepper, to taste
Optional Toppings
• Fresh thyme
• Extra Gruyere cheese
• Cracked black pepper
• Fresh parsley
• Drizzle of olive oil or avocado oil
Instructions
Step 1: Slice the Onions
Slice the onions into very thin rings using a mandoline slicer, if available.
Thin, even slices help the onions caramelize more evenly.
Step 2: Caramelize the Onions
Preheat a Dutch oven with butter over medium-low heat.
Add the sliced onions and a pinch of sea salt.
Cook, stirring occasionally, until the onions are deeply caramelized, about 45 minutes.
Step 3: Cook the Sweet Potato Toasts
While the onions caramelize, cook Roots Farm Fresh Sweet Potato Toasts according to package directions.
Set aside until ready to assemble the soup.
Step 4: Deglaze the Pot
Once the onions are deeply caramelized, add the dry white wine and a splash of dry sherry.
Bring to a boil and cook until the liquid reduces by about half.
Step 5: Add the Flour and Stock
Add the flour and stir until it is fully dispersed into the onions with no clumps remaining.
Pour in the vegetable or beef stock and bring the soup to a boil.
Boil for 5 minutes, then season with sea salt and black pepper to taste.
Step 6: Assemble the Soup
Place an oven rack in the top third of the oven and turn the oven to broil.
Transfer the soup into four oven-safe ramekins.
Place the cooked sweet potato toasts over the soup and sprinkle with freshly grated Gruyere cheese.
Step 7: Broil and Serve
Place the ramekins on a baking sheet.
Broil for 3 to 4 minutes, or until the cheese is melted, bubbling, and golden brown.
Watch closely to avoid burning. Serve warm.
