  • 1 teaspoon Fresh thyme (Leaves only, roughly chopped)
  • 3 cloves Garlic cloves (Pealed and sliced)
  • 200 g Sprouting broccoli (Separate florets and finely chop stalks)
  • 2 tablespoons Plain flour (All‑purpose)
  • 1 litre Whole milk (Room temperature)
  • 150 g Cheddar cheese (Grated)
  • 30 g Parmesan cheese (Grated; can use vegetarian alternative)
  • 100 g Fresh spinach (Roughly chopped)
  • 450 g Dried macaroni (Any short pasta shape)
  • 20 g Flaked almonds (To sprinkle on top)
  • to taste Salt
  • to taste Black pepper

Instructions

  1. Prepare the vegetables

    Trim the root ends off the leeks, split them lengthwise, rinse well to remove grit and slice thinly. Separate broccoli florets and finely chop the stalks. Peel and slice the garlic cloves.

    Time: PT10M

  2. Sauté aromatics

    Place the casserole pan over medium heat, melt the butter, add the thyme leaves, sliced leeks, garlic and chopped broccoli stalks. Cook, stirring, until fragrant, about 5 minutes.

    Time: PT5M

    Temperature: medium

  3. Soften the vegetables

    Add the broccoli florets to the pan and continue cooking, stirring occasionally, for a further 15 minutes until all veg are tender but still retain colour.

    Time: PT15M

    Temperature: medium

  4. Create the roux

    Sprinkle the plain flour over the softened vegetables and stir for 2 minutes to cook out the raw flour taste.

    Time: PT2M

    Temperature: medium

  5. Add milk and thicken

    Gradually whisk in the litre of milk, ensuring no lumps form. Bring the mixture to a gentle simmer and cook 5‑7 minutes, stirring, until the sauce thickens and coats the back of a spoon.

    Time: PT7M

    Temperature: medium

  6. Incorporate cheeses

    Remove the pan from the heat and stir in the grated cheddar and parmesan until completely melted and smooth.

    Time: PT3M

  7. Add spinach

    Stir the chopped spinach into the hot sauce; it will wilt in the residual heat.

    Time: PT2M

  8. Blend to a silky green sauce

    Using the immersion hand blender, blend the sauce directly in the pan until it becomes a smooth, luminous green puree.

    Time: PT2M

  9. Par‑cook the macaroni

    Bring a large pot of salted water to a rolling boil. Add the dried macaroni and cook for 5 minutes – it should be very al‑dente as it will finish cooking in the oven.

    Time: PT5M

    Temperature: 100°C

  10. Combine pasta and sauce

    Drain the macaroni and transfer it to a large baking dish. Pour the green cheese sauce over the pasta, fold in the broccoli florets, and mix gently to coat evenly.

    Time: PT3M

  11. Add toppings

    Sprinkle the remaining grated parmesan and the flaked almonds evenly over the top of the dish.

    Time: PT1M

  12. Bake

    Place the baking dish in a pre‑heated oven at 180°C (350°F) and bake for 30 minutes, or until the top is golden and the sauce is bubbling.

    Time: PT30M

    Temperature: 180°C

  13. Rest and serve

    Remove from the oven, let the mac and cheese rest for 5 minutes before serving so the sauce sets slightly.

    Time: PT5M
