Upside-Down Beef Cottage Pie

While the tomatoes are roasting, peel the potato and cut into 2cm chunks. Finely chop the brown onion (see ingredients list). Finely chop the garlic (or use a garlic press). Grate the carrot (unpeeled).

Add the potato to the saucepan of boiling water and cook until easily pierced with a knife, 10-15 minutes. Drain and return to the saucepan. Add the butter, milk and salt and mash with a potato masher or fork until smooth. Cover with a lid to keep warm.

In a large frying pan, heat a good drizzle of olive oil over a medium-high heat. Add the onion and cook, stirring, until softened, 3-4 minutes. Increase the heat to high, add the beef mince and cook, breaking up with a spoon, until browned, 4-5 minutes. Add the garlic and Italian herbs (see ingredients list) and cook until fragrant, 1 minute.

Add the carrot to the frying pan and cook, stirring, until softened, 3-5 minutes. Add the diced tomatoes and beef stock. Stir until well combined. Reduce the heat to medium and simmer until thickened slightly, 4-5 minutes. Stir through the baby spinach leaves until wilted, 1 minute. Season to taste with salt and pepper. While the sauce is simmering, pick and thinly slice the basil leaves. TIP: Seasoning is key in this dish! Taste and add more salt or pepper if you like.
