How To Make This Soup?

Let’s break this down step by step. Trust me, the process is rewarding and surprisingly simple.

Step 1: Caramelize the Onions

Heat the olive oil and plant-based butter in a large pot over medium heat. Add the sliced onions and sprinkle with sea salt. Stir often for about 30-40 minutes, or until the onions turn an amber color. Patience is essential here; don’t rush this step. You’re aiming for that beautifully caramelized texture and sweet flavor.

Step 2: Add Garlic and Sugar

Once your onions reach that golden hue, toss in the minced garlic and coconut sugar. Stir for a couple more minutes until fragrant. The sugar helps enhance the sweet notes of the soup.

Step 3: Deglaze the Pot

Pour in the red wine, scraping up any stuck bits from the bottom of the pot. This adds depth and complexity to the soup. Let the wine simmer for a few minutes until it reduces slightly.

Step 4: Add Broth and Spices

Stir in the vegetable broth, Worcestershire sauce, bay leaves, thyme, smoked paprika, and black pepper. Bring the mixture to a simmer, then reduce the heat to low. Allow it to gently simmer for 30 minutes.

Step 5: Make the Bread Toppings

While the soup simmers, preheat your oven to 400°F (200°C). Place the slices of French bread on a baking sheet. Toast them for about 10 minutes until golden brown, flipping halfway. If you’d like, cheese can be added to the slices for a melty topping.

Step 6: Serve the Soup

Once the soup is done, remove the bay leaves. Ladle the hot soup into bowls, place a slice of toasted bread on top, and sprinkle generously with Gruyère cheese. You can broil them for an extra touch—just a minute under the broiler until the cheese is bubbly and golden.

Tips for Success

  • Be Patient: Caramelizing onions takes time. Don’t rush it, or else the flavor won’t be as rich.
  • Quality Matters: Use great vegetable broth and cheese. These ingredients impact the overall taste.
  • Wine Selection: Opt for a dry, not overly sweet red wine for the best flavor.
  • Fresh Herbs: Fresh thyme and bay leaves provide better flavor than dried versions. Use fresh when possible.
  • Adjust to Taste: If the soup is too sweet, add a splash more vinegar or some lemon juice to brighten it.

How to Store the Leftovers?

If you’re lucky enough to have leftovers, they can easily be stored. Allow the soup to cool completely before transferring it to an airtight container. Store it in the refrigerator for up to 5 days. For longer storage, consider freezing it. Freeze in portions and allow it to thaw overnight when you’re ready to enjoy it again.

Recommended Side Dishes for Vegetarian French Onion Soup

Pairing sides can elevate your meal further. Here are some tasty suggestions:

1. Caesar Salad: A classic Caesar salad can add a crunchy, tangy contrast to the rich soup. Crisp romaine lettuce, creamy dressing, and croutons make for a delightful mix.

2. Quinoa Salad: A chilled quinoa salad with diced cucumbers, tomatoes, and a zesty lemon dressing brings freshness and texture that complements the soup.

3. Roasted Vegetables: Seasoned and roasted vegetables like asparagus, Brussels sprouts, or root veggies can provide beautiful flavors. Their caramelization brings out natural sweetness, just like in the soup.

4. Spinach and Artichoke Dip: Warm, cheesy, and savory, this dip is a fantastic appetizer. Pair it with pita chips, and it sets a fun tone for your meal.

Substitute Options for Ingredients

Sometimes an ingredient isn’t available. Here are some handy substitutes:

1. Onions: If you’re out of yellow onions, you can use sweet onions or even shallots for a different flavor profile.

2. Gruyère Cheese: If Gruyère is hard to find, Swiss cheese or provolone can work as alternatives. Both melt well and offer a similar creamy experience.

3. Red Wine: For those avoiding alcohol, consider using balsamic vinegar and water mixed in a 1:1 ratio for a similar flavor without the wine.

4. Vegetable Broth: Homemade vegetable broth is ideal, but in a pinch, you can use water with added herbs and spices for flavor.
