    🔄 Optional Add-Ins & Variations

    • Fully cooked chicken or bacon make great additions. Stir them in when adding the florets for extra protein and flavor.

    🥣 Why This Recipe Works

    This recipe uses broccoli stalks blended with onions and garlic to create a naturally creamy base without flour or thickeners. Roasting the broccoli florets brings out deep, caramelized flavors, while adding cheese gradually ensures a smooth, velvety texture. It’s a simple yet flavorful approach that keeps carbs low and taste high.

    🧊 Storage & Reheating

    Store leftover soup in an airtight container in the refrigerator for up to 4 days. To reheat, warm gently on the stove over low heat, stirring occasionally to keep the cheese smooth. Avoid boiling to prevent the cheese from separating. This soup also freezes well — thaw overnight in the fridge before reheating.

    🙋‍♀️ Common Questions

    Can I use vegetable broth instead of chicken stock?

    Yes! Vegetable broth works well if you want a vegetarian option or a lighter flavor.

    Can I make this soup dairy-free?

    You can try using dairy-free cheese and coconut cream, but the flavor and texture will differ from the original recipe.

    How can I thicken the soup without flour?

    This recipe relies on blending broccoli stalks for natural thickness. You can also add cauliflower or use a small amount of xanthan gum if needed.

    Can I prepare this soup ahead of time?

    Yes, it stores well in the fridge for up to 4 days and freezes nicely for longer storage.

    🥖 How This Recipe Compares to Traditional Biscuits

    Traditional biscuits use wheat flour, baking soda, and milk or buttermilk—adding carbs and gluten. This version mimics the texture and comfort of classic biscuits using just pork rinds, eggs, and cheese. You still get a golden, tender result—without grains, sugar, or carb spikes.
