Cauli Mac & Cheese with Garlic Butter Breadcrumbs

Steps

1. Bring a medium pot of hot salted tap water to the boil (with a lid).
2. Chop cauliflower. Add pasta and cauliflower to pot of boiling water and cook for 8-10 minutes, until just tender. Reserve 1/4 cup pasta water, then drain well. Return pasta and cauliflower to pot with spinach and oil.
3. Mince garlic. Heat butter in a large fry-pan on medium heat. Add garlic, breadcrumbs and a pinch of salt and cook, stirring for 3-4 minutes, until golden. Transfer to a small bowl and wipe pan clean. Reserve pan.
4. Thinly slice leek and grate cheese. Return pan to medium heat with oil and cook leek for 7-8 minutes, stirring, until tender. Add to pot with cooked and drained pasta. Keep pan on heat and reduce to low-medium.
5. Melt butter in pan, add classic spice blend and flour and cook, stirring constantly, for 1-2 minutes, until golden and fragrant. Gradually whisk in milk and 1/4 cup of reserved pasta water, until smooth. Bring to a gentle simmer and cook for about 2 minutes, until thickened. Stir frequently.
6. When sauce has thickened, stir in cheese and season to taste with salt and pepper. If sauce is too thick, add a splash more milk. Pour into pot with cooked pasta and stir to combine.
7. Cauli pasta sprinkled with breadcrumbs.
