Preheat oven to 220C/200C fan-forced. Line a baking tray with baking paper.
Cut 3mm-thick slices along each potato, being careful not to cut the whole way through. Place on prepared tray. Drizzle with oil. Season with salt and pepper. Roast for 1 hour or until tender.
Combine bolognese and pesto in a bowl. Season with salt and pepper. Spoon onto the potatoes, pushing into the cuts. Sprinkle with cheese. Bake for a further 10 to 15 minutes or until bolognese is heated through and cheese is melted and golden.
Stand potatoes for 5 minutes. Sprinkle with basil. Serve with salad.
