Step 1
Preheat the oven to 180ºC. Spray a frying pan with low-calorie cooking spray, and set on a low heat. Add the leeks and garlic, and gently fry for 5 minutes — until just softened.
Step 2
Add the sprouts to an ovenproof dish. In a bowl, combine the spreadable cheese, milk, 40g Cheddar, Dijon mustard, and garlic granules. Season to taste with salt and pepper. Mix until smooth.
Step 3
Add the leeks to the sprouts, and mix. Pour over the cheese sauce, then mix further to coat. Cook in the oven for 20 minutes.
Step 4
In a small bowl, combine the breadcrumbs, thyme, and remaining Cheddar cheese. Season to taste with salt and pepper.
Step 5
Sprinkle the breadcrumbs evenly over the sprouts and return to the oven for 10 minutes, until golden brown.

Can I just check that it’s 500ml of milk? The picture shows a paste once the cream cheese, cheese and milk etc are combined?? 500ml of milk did not make a paste!!
Its in the oven using the ingredients as stated so fingers crossed 😂
