Is Mustard Gluten-Free?

Most mustard varieties are gluten-free, as they are typically made from mustard seeds, vinegar, and spices. However, it’s essential to check the label, as some brands may add ingredients or flavorings that contain gluten. I use this brand of mustard.

The Crispy Sage and Onion Topping

Crispy sage and onion topping brings exceptional flavor and crunch to cauliflower soup. You can serve it by drizzling the infused oil along with the crispy bits, or drain the fried onions and sage on paper towel for a lighter option.

Common mistakes to avoid when making Cheesy Cauliflower Soup:

• Overcooking the Cauliflower: Cooking it too long can make the soup mushy. Aim for tender but not falling apart.
• Not Seasoning Early: Waiting until the end to add salt and pepper can lead to flavorless cauliflower. Season the broth while cooking.
• Blending Too Quickly: If you blend while the soup is too hot, it can splatter. Allow it to cool slightly before blending, or use an immersion blender.
• Using Low-Quality Cheese: Pre-shredded cheese can lead to a grainy texture due to anti-caking agents. Freshly grated cheese melts better.
• Skipping the Cream: If you want a creamy texture, don’t skip the heavy cream. Alternatively, use a blend of cream and milk for a lighter option.
• Boiling soup after adding cream: High heat can cause the fat in the cream to separate from the liquid, resulting in a curdled appearance and texture. Gently heat the soup after adding cream and cheese, keeping it at a simmer rather than a boil.
• Ignoring Texture: If you prefer a chunkier soup, blend only part of the mixture and leave some cauliflower intact.
• Not Tasting as You Go: Always taste during the cooking process to adjust flavors, especially after adding cheese. 

Storing

Allow the soup to cool to room temperature before storing to prevent condensation, then store in the fridge for 3-4 days. 

If you want to keep it longer, freeze the soup in portion-sized containers. It can last for about 2 months in the freezer.

When reheating, do so gently on the stovetop or microwave. You may need to add a splash of water, broth, or cream if the soup is too thick.
