Instructions

Get Prepped
1

Preheat your oven to 220°C/200°C fan/gas mark 7. Bring a large saucepan of water with 1/2 tsp salt to the boil for the potatoes.

Peel and slice the sweet potato and white potatoes into 1cm thick rounds. 

Once boiling, add both types of potato to the water and simmer until just tender, 8-12 mins.

In the meantime, peel and grate the garlic (or use a garlic press). Halve the tomatoes. 

Sauce Things Up
2

In a small bowl, combine the breadcrumbs with the oil for the breadcrumbs (see pantry for amount). Season with salt and pepper. Set aside. 

Heat a drizzle of oil in a large frying pan on medium heat.

Once hot, add half the garlic and cook until fragrant, 1 min. 

Stir in the creme fraiche, veg stock paste, grated hard Italian style cheese and water for the sauce (see pantry for amount). Bring to the boil, then remove from the heat.

Hey Pesto
3

Stir the pesto through the sauce, then taste and season with salt and pepper if needed.  

Once ready, drain the potatoes in a colander and place them in layers in an appropriately sized ovenproof dish. Pour over the creamy pesto sauce.

Sprinkle the crumbs evenly over the creamy potatoes. 

Tomato Time
4

Lay the tomato halves onto one side of a large baking tray, cut-side up.

Spread the tomatoes with the remaining garlic, then season with salt and pepper. 

Cook the Gratin
5

Pop the gratin on the other side of the baking tray.

Bake on the top shelf of your oven until the gratin is golden brown and bubbling and the tomatoes have softened, 15-20 mins.

Serve
6

When everything's ready, share the gratin between your plates. 

Serve the roasted tomatoes and salad alongside, drizzling the balsamic glaze over the salad leaves to finish.

Enjoy!

Review summary

Updated on Feb 2026
  • Flavour: The creamy pesto sauce was praised for being fantastic and indulgent, though some found the overall dish a bit bland.
  • Ease of prep: Several reviewers noted the dish was easy to prepare, but many found the cooking time insufficient for properly tender potatoes.
  • Suggestions: Consider adding more vegetables or protein to make it a more complete meal; some enjoyed it with chicken or fish.
  • Portions: Many felt this worked better as a side dish than a main course due to its potato-heavy composition.
  • Texture: For improved texture, try adding crushed cashews on top or incorporating additional vegetables into the gratin.
