Equipment
- Dutch oven or large pot
Ingredients
- 4 large yellow or sweet onions (5-6 medium), thinly sliced
- 2 cloves garlic, minced
- 2 tbsp olive oil
- 1 tbsp plant-based butter
- 2 tsp brown sugar
- 1 (14.9-ounce) can Guinness beer
- 4 cups low-sodium vegetable broth
- 1 tsp dried thyme (or 1 tbsp fresh thyme)
- ¾ tsp salt, adjust to taste
- ½ tsp black pepper
- 1 tbsp light soy sauce (or vegan Worcestershire sauce)
- 2 tbsp balsamic vinegar (start with 1 and add more if desired)
- Slices of plant-based white cheddar
- Crusty bread for dipping
Instructions
- Caramelize the Onions: Heat 2 tbsp olive oil and 1 tbsp butter in a large pot over medium-low heat. Add the sliced onions, cover, and cook for 8–10 minutes, until the onions start to become translucent.Remove the lid and continue cooking, stirring occasionally, for 40–50 minutes, or until the onions develop a deep golden-brown color. Once they begin to caramelize, stir in 2 tsp brown sugar and continue cooking, stirring occasionally.
- Add Seasonings & Deglaze with Guinness: Stir in the 2 cloves minced garlic, 1 tsp dried thyme, ¾ tsp salt, and ¼ tsp black pepper, cooking for 1 minute until fragrant.Pour in the 14.9-ounce can Guinness beer, scraping up any browned bits from the bottom of the pot. Let it simmer for 10 minutes until the alcohol cooks off and the liquid reduces slightly but does not fully evaporate.
- Add Broth & Simmer: Stir in 4 cups vegetable broth and bring the soup to a gentle simmer, cover with the lid slightly tilted, and let it cook for 20 minutes, stirring occasionally.
- Finish & Adjust Seasoning: Tste the soup and adjust salt and pepper as needed. Stir in the 1 tbsp soy sauce and 1 tbsp balsamic vinegar, then taste again and adjust if desired.
- Melt the Cheese: While the soup simmers, preheat the broiler. Ladle the soup into oven-safe bowls, top with 1–2 slices of vegan cheddar, and place under the broiler until the cheese is melted, bubbly, and golden.
- Serve & Enjoy: Remove from the oven and serve hot with crusty bread for dipping. Enjoy!
