Squash and Kelp Pesto Pasta with Sweetcorn and Olives

Squash and Kelp Pesto Pasta with Sweetcorn and Olives

Feb 21, 2026Oliver Ford

Pesto doesn't have to mean basil. This homemade squash and kelp pesto is sweet, earthy, and deeply savoury, with Algee kelp powder blended right through it for a natural boost of iodine, magnesium, and iron. Tossed with pasta, sweetcorn, and olives, it makes a proper nutritious lunch that feels anything but boring. Simple ingredients, genuinely good.

Prep time: 5 mins  |  Cook time: 25 mins  |  Serves: 2

Algee product used: Kelp Powder

Ingredients

  • 200g pasta
  • 300g butternut squash, peeled and cubed
  • 1 garlic clove
  • 30g pine nuts or walnuts, toasted
  • 30g Parmesan or pecorino, grated, plus extra to serve
  • 3 tbsp olive oil, plus extra for roasting
  • Half a lemon, juiced
  • 100g sweetcorn (tinned or fresh)
  • 60g olives, pitted and roughly chopped
  • 1 tsp Algee kelp powder
  • Salt and black pepper

Method

  1. Preheat the oven to 200C. Toss the squash in olive oil, season, and roast for 20-25 minutes until soft and golden.
  2. Cook the pasta in well-salted boiling water according to packet instructions. Reserve a mugful of pasta water before draining.
  3. Add the roasted squash to a blender with the garlic, nuts, Parmesan, olive oil, and lemon juice. Blend until smooth. Stir in the Algee kelp powder, which adds a natural mineral depth that rounds out the sweetness of the squash. Season to taste.
  4. Toss the drained pasta with the pesto, adding a splash of pasta water to loosen to your preferred consistency. Fold through the sweetcorn and olives.
  5. Plate up with an extra grating of Parmesan and a pinch of Algee kelp powder on top. Serve straight away.

Notes

The kelp powder blends into the pesto seamlessly, adding iodine, magnesium, and iron without any fishiness. For a chunkier texture, mash the squash with a fork and stir the other ingredients through rather than blending. Leftovers keep well in the fridge for a day with a drizzle of olive oil on top.
