Why This Recipe Works

This recipe works by blending the vibrant color of fresh spinach directly into the cheese sauce, ensuring every bite is packed with iron and flavor. By using the stalks of the broccoli in the base and reserving the florets for texture, you eliminate food waste while maximizing the sweet, nutty essence of the brassica family.

I personally recommend this method because it sneaks essential greens into a meal that even the pickiest eaters will adore. The addition of flaked almonds on top provides a much-needed crunch against the creamy pasta, balancing the texture perfectly for a sophisticated dining experience.

Step-by-Step Instructions

Preparation and Base

  1. Preheat your oven to 180ºC/350ºF/gas 4.
  2. Trim, halve, and wash the leek thoroughly to remove grit.
  3. Finely slice the leek, garlic, and broccoli stalks while setting the florets aside.
  4. Place the sliced vegetables and thyme in a large casserole pan with the butter.
  5. Cook over medium heat for 15 minutes until softened.

Building the Sauce

  1. Stir the flour into the vegetable mixture to create a roux.
  2. Pour in the milk slowly while whisking to prevent lumps.
  3. Simmer for 10 minutes until the sauce coats the back of a spoon.

Combining and Baking

  1. Cook the macaroni in boiling salted water for 5 minutes, then drain immediately.
  2. Grate the Parmesan and most of the Cheddar into the sauce and mix well.
  3. Whiz the sauce and spinach in a blender until smooth.
  4. Season with salt and pepper, then stir in the pasta and reserved florets.
  5. Transfer to a 25cm x 35cm baking dish, topping with remaining cheese and almonds.
  6. Bake for 30 minutes until golden and bubbling.

Chef Tips for Perfect Results

  • Always blanch your broccoli florets for two minutes if you prefer them slightly softer.
  • Use a high-speed blender to ensure the spinach provides a vibrant green hue without bits of leaf.
  • Grate your own cheese from a block to ensure it melts smoothly without anti-caking agents.
  • Toast your flaked almonds in a dry pan before sprinkling on top for a richer flavor profile.

Common Mistakes to Avoid

One common mistake is adding the milk too quickly, which creates flour clumps; avoid this by adding just a splash at a time. Another error is overcooking the pasta before baking; ensure you stop at the 5-minute mark to prevent the noodles from becoming mushy in the oven. Finally, season the sauce at the very end to match the saltiness contributed by the different cheeses.
