Ingredients

• 1 large head of cauliflower, cut into florets
• 1 medium yellow onion, chopped
• 3 cloves garlic, minced
• 3 cups vegetable broth or chicken broth (ensure it’s from a trusted source)
• 1 cup unsweetened almond milk (or any plant-based milk)
• 2 tablespoons olive oil
• 1 teaspoon ground cumin
• 1/2 teaspoon smoked paprika
• Salt and freshly ground black pepper, to taste
• 1 tablespoon fresh lemon juice
• 4 slices bread (white or whole wheat, ensure no non-permissible ingredients)
• 1 cup shredded mozzarella cheese (or a -certified cheese)
• Butter or olive oil for grilling the sandwiches
• Fresh parsley or chives for garnish (optional)

How To Make Cauliflower Bisque with Grilled Cheese Croutons

Step 1: Roast the Cauliflower

Preheat your oven to 400°F (200°C). Toss the cauliflower florets with 1 tablespoon olive oil, cumin, smoked paprika, salt, and pepper. Spread them out on a baking sheet in a single layer and roast for 25-30 minutes, or until the cauliflower is tender and slightly caramelized. Roasting adds depth and sweetness to the bisque.

Step 2: Sauté Onions and Garlic

While the cauliflower roasts, heat the remaining 1 tablespoon of olive oil in a large pot over medium heat. Add the chopped onions and cook until translucent, about 5-7 minutes. Add the minced garlic and cook for another 1-2 minutes until fragrant, being careful not to burn it.

Step 3: Simmer the Soup

Add the roasted cauliflower to the pot along with the vegetable broth. Bring to a simmer and cook for 10 minutes, allowing all the flavors to meld together.

Step 4: Blend Until Smooth

Using an immersion blender, carefully puree the soup until completely smooth. Alternatively, transfer the soup in batches to a blender and puree until silky. Return the soup to the pot if you used a blender.

Step 5: Add Creaminess and Brightness

Stir in the almond milk and lemon juice. Adjust seasoning with more salt and pepper if needed. Warm the soup gently over low heat, but do not boil.

Step 6: Prepare Grilled Cheese Croutons

Butter one side of each bread slice. Place two slices, buttered side down, on a skillet over medium heat. Sprinkle shredded mozzarella evenly on top, then place the other slice of bread on top, buttered side up. Grill until golden and cheese is melted, about 3-4 minutes per side. Remove and let cool slightly.

Step 7: Cut and Serve

Cut the grilled cheese sandwiches into small, bite-sized cubes to create croutons. Ladle the warm bisque into bowls, top with grilled cheese croutons, and garnish with fresh parsley or chives if desired.

Expert Tips

• Roasting is key: Don’t skip roasting the cauliflower—it adds a wonderful nutty flavor that boiling alone can’t achieve.
• Use an immersion blender: This makes pureeing easier and safer, especially with hot liquids.
• Choose good-quality bread: The grilled cheese croutons are a highlight, so pick bread that crisps up nicely without falling apart.
• Melt the cheese thoroughly: Cover the skillet briefly with a lid while grilling the sandwiches to help the cheese melt evenly.
• Adjust consistency: If the bisque feels too thick, add a splash more broth or almond milk until you reach your desired texture.
• Make ahead: The soup can be made a day in advance and reheated gently before serving.

Variations and Customizations

• Add herbs: Stir in fresh thyme or rosemary during cooking for an herbal note.
• Spice it up: Add a pinch of cayenne or red pepper flakes to give the bisque a subtle kick.
• Use different cheeses: Try cheddar, provolone, or a blend of -certified cheeses for varied flavor profiles in your grilled cheese croutons.
• Make it vegan: Use vegan cheese and plant-based butter for the grilled cheese. Ensure broth is vegetable-based.
• Add potatoes: For extra creaminess, add a peeled and chopped potato to the broth while simmering the soup.
• Top with crunchy nuts: Toasted pine nuts or slivered almonds sprinkled on top add a lovely crunch.

How to Store Leftovers

Store any leftover bisque in an airtight container in the refrigerator for up to 3 days. When reheating, warm gently on the stove over low heat, stirring occasionally. Avoid boiling to maintain the soup’s creamy texture. Keep grilled cheese croutons separate and reheat in a toaster oven or skillet to retain their crispiness. If storing grilled cheese croutons is not ideal, consider making them fresh just before serving.

FAQ

Can I use frozen cauliflower for this recipe?

Yes, frozen cauliflower works well and is a convenient option. Thaw and drain excess water before roasting to avoid sogginess.

What can I substitute for almond milk?

You can use any unsweetened plant-based milk such as oat, soy, or coconut milk. Regular dairy milk also works if preferred.

How do I make the soup creamier without adding cream?

Roasting the cauliflower and adding a potato or blending the soup thoroughly results in a naturally creamy texture without heavy cream.

Can I prepare the grilled cheese croutons ahead of time?

It’s best to prepare them fresh for optimal texture. However, you can make them in advance and reheat briefly in a skillet or oven to restore crispiness.
