Instructions
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
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
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
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
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
Incorporate cheeses
Remove the pan from the heat and stir in the grated cheddar and parmesan until completely melted and smooth.
Time: PT3M
Add spinach
Stir the chopped spinach into the hot sauce; it will wilt in the residual heat.
Time: PT2M
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
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
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
Add toppings
Sprinkle the remaining grated parmesan and the flaked almonds evenly over the top of the dish.
Time: PT1M
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
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

Chef Tips from the Video

- Fresh thyme adds a bright note – don’t substitute with dried unless you increase the amount.
- Toast the almond flakes lightly in a dry pan before sprinkling for extra aroma.
Troubleshooting
Sauce is lumpy
Return the pan to low heat and whisk vigorously, or finish blending with the immersion blender.
Sauce is too thin
Simmer a few minutes longer to reduce, or whisk in a teaspoon of extra flour mixed with cold water.
Pasta is overcooked
Next time, reduce the initial boil to 4 minutes; the pasta will finish cooking in the oven.
Almonds burn during baking
Add the almonds during the last 10 minutes or toast them separately and sprinkle after baking.
