Peel the garlic and slice it very thinly. Pick the leaves from the rosemary sprigs and coarsely chop. Toss the garlic and rosemary with the gnocchi, cherry tomatoes, salt and black pepper directly in the baking dish. Drizzle with the olive oil and gently toss to combine. Spread into an even layer.
3 cloves garlic, 2 stalks rosemary, 1 pound potato gnocchi, 1 pint cherry tomatoes, 1/2 tsp flaky salt, 1/2 tsp ground black pepper, 2 Tbsp olive oil
Put the baking dish into the oven and cook, stirring halfway through, until the tomatoes have burst and are starting to brown, about 15 minutes for combi steam or 20-25 minutes for standard ovens.
Remove from the oven. Working quickly, add the spinach, cream and pesto to the pan. Gently toss through but don’t worry too much if it’s a little unevenly mixed.
2 cups baby spinach leaves, 3 Tbsp heavy cream, 3 Tbsp basil pesto
Return the pan to the oven for 2-3 minutes, until the spinach has wilted. Remove from the oven and toss again so the cream, pesto and roasted tomatoes form a creamy sauce. Sprinkle with grated parmesan cheese and red pepper flakes if desired. Serve hot.
2 oz Parmesan cheese, 1 tsp red pepper flakes
