Directions

  1. 1Add onions into a pan with butter & a pinch of salt, then cook over a medium heat for 30-40 mins until dark, golden & caramelised.
  2. 2Add stock & thyme, turn heat to medium-high, cook for another 10 minutes until most of the stock has been absorbed and evaporated. Set aside until ready to use.
  3. 3Slice 1 small baguette into discs, add into a bowl with olive oil, thyme & salt, then mix together until evenly coated. Lay bread out onto a baking tray & cook in the oven for 5-10 mins until golden & crisp. Remove from oven, place into blender & blitz into coarse breadcrumbs.
  4. 4Melt butter in a pan over a medium heat then mix in the flour until combined. Cook for a few mins to remove floury taste, then gradually whisk in all the milk, taking your time to ensure no lumps form.
  5. 5Once the milk is mixed in, bubble sauce for a few mins, constantly stirring so bottom doesn’t burn.
  6. 6Remove bechamel from the heat, add in 2/3rds of caramelised onions, cheeses, mustard, nutmeg & salt & pepper to taste. Set sauce aside until ready to use.
  7. 7Bring a large pot of water to a boil, season with salt then add in the dried pasta. Cook for 8-10 mins, until just al dente. Reserve some of the pasta water then strain pasta.
  8. 8Place pasta in large pan, pour over sauce & mix. If sauce too thick, add splash of pasta water & mix. Smooth it out, top with breadcrumbs & remaining caramelised onions.
  9. 9Place under grill for 5 mins to toast breadcrumbs a little more, remove from the oven & serve.
