Creamy Pesto Pasta Bake

This creamy pesto pasta bake is a simple meal to make when you want something delicious that will please the whole family!

I love pesto pasta, and often make my One Pot Cheesy Pesto and Spinach Pasta, but this recipe is perfect when you have a little more time and want a meal that everyone’s going to love.

The creamy bechamel sauce mixed with the pesto, basil and peas makes a seriously yummy pairing for the pasta – and the mozzarella topping is just the cherry on top!

Creamy Pesto Pasta Bake – The Ingredients

  • Penne pasta – macaroni would also be great here!
  • Butter, plain flour, milk – these simple ingredients make your white sauce. You can use salted or unsalted butter. Semi-skimmed or whole milk is best.
  • Pesto – simple green pesto is perfect. You can make your own, if you like.
  • Basil – optional, but it brings a fresh flavour to the dish.
  • Peas – use frozen peas.
  • Mozzarella – you can either use a ball of mozzarella or grated mozzarella- whichever is easier for you to get hold of. I used grated.

Top Tips

  1. Get ahead

    You can make the pesto pasta bake in advance. Make up to the point where you would put it in the oven, then refrigerate for up to a week. Cook until golden brown when you’re ready to eat. If you do this, cook the pasta for one minute less so that it doesn’t go soggy.

  2. Making the white sauce

    My fail safe way is to melt the butter, whisk in the flour then gradually add the milk, whisking all the time. Bring to a gentle simmer, by which time it should have thickened.

  3. Additions

    You could add some cooked chicken, spinach or courgette slices.
