Preheat the oven to 425 f / 220 c.

Place the diced onion, garlic, red pepper, halved cherry tomatoes and gnocchi on a sheet pan.

Give it a mix to combine everything then drizzle over the olive oil and sprinkle over the salt and red pepper flakes. Stir well to coat the gnocchi in the oil.

Place the pan in the oven and bake for 30 to 40 minutes, stirring once at the halfway mark.

The gnocchi should be soft on the inside and golden brown on the outside and feel crispy when you run a knife over it. Some of the cherry tomatoes will be beginning to char but take it out of the oven if you think they are starting to burn.

Give it another mix to coat the gnocchi in the tomato juices and serve.
