Ingredients
• 1 medium broccoli, 300 g / 10.6 oz
• 1/2 medium cauliflower, 300 g / 10.6 oz
• 2 tablespoons ghee or other healthy cooking fat, 30 g / 1.1 oz

Instructions
1. Prepare the slow cooker and sauté the aromatics. Set a 5- to 6-quart (4.7- to 5.7-L) slow cooker to your desired setting. Cut the broccoli and cauliflower into florets; peel and roughly chop the broccoli stalks. Heat ghee in a skillet over medium-high heat. Add the chopped onion and cook for 5-8 minutes until lightly browned. Stir in the minced garlic, sliced leek, and celery, and cook for another 1-2 minutes until fragrant.2. Combine and cook. Transfer the sautéed vegetables to the slow cooker. Add the cauliflower, broccoli pieces, vegetable stock, and water. Cover and cook on high for 2-3 hours or on low for 4-6 hours, until the vegetables are very tender.3. Blend to creamy perfection. Slowly pour the heavy cream into the soup while stirring. Add the shredded Cheddar cheese and chopped parsley, reserving some of each for garnish. Use an immersion blender to process the soup directly in the slow cooker until it reaches your desired consistency, from chunky to silky smooth.4. Season and serve. Season generously with salt and pepper to taste. Ladle the hot soup into bowls and garnish with the reserved Cheddar cheese and fresh parsley before serving. Store leftovers in an airtight container in the refrigerator for up to 5 days.

Pro Tips
• For the smoothest soup, use a block of sharp Cheddar and shred it yourself. Pre-shredded cheeses contain anti-caking agents that can result in a grainy texture.
• If using a standard blender instead of an immersion blender, work in batches and never fill it more than halfway. Remove the center cap from the lid and cover the opening with a folded kitchen towel to allow steam to escape safely.
• For perfect reheating, gently warm the soup on the stovetop over low heat. Avoid boiling, as high heat can cause the cream and cheese to separate.
