Cauliflower White Bean Soup with Mustardy Croutons. in Steps

Step 1: Sauté the Aromatics
In a large pot, heat 1 tablespoon of olive oil over medium heat. Add the diced sweet onion and sauté until translucent, about 5 minutes. Then, stir in the minced garlic, dried thyme, and dried rosemary, cooking for another minute until fragrant.
Step 2: Add the Cauliflower and Beans
Add the cauliflower florets to the pot, followed by the drained and rinsed white beans. Stir to combine all the ingredients, allowing them to mingle for a couple of minutes.
Step 3: Pour in the Stock
Pour in 4 cups of vegetable or chicken stock, bringing the mixture to a gentle boil. Reduce the heat and let it simmer for about 20 minutes, or until the cauliflower is tender.
Step 4: Blend the Soup
Once the cauliflower is tender, use an immersion blender to puree the soup until smooth. Alternatively, you can carefully transfer the soup to a blender in batches. Blend until creamy and return the soup to the pot.
Step 5: Season to Taste
Taste the soup and season with kosher salt and pepper as needed. Keep it warm on low heat while you prepare the croutons.
Step 6: Make the Mustardy Croutons
Preheat your oven to 375°F (190°C). In a mixing bowl, combine the bread chunks with the melted butter and Dijon mustard. Toss until the bread is well coated. Spread the croutons in a single layer on a baking sheet and bake for about 10-15 minutes, or until golden and crispy.
Step 7: Serve and Garnish
Ladle the creamy cauliflower white bean soup into bowls. Top with a generous handful of mustardy croutons and garnish with fresh thyme. Serve hot and enjoy every comforting bite!

Things That Go Wrong

- Flavor is bland: Ensure to season adequately with salt and pepper, and consider adding a splash of lemon juice for brightness.
- Croutons are too hard: Keep an eye on them while baking, as oven temperatures can vary. Adjust baking time as necessary.
