Bring the olive oil to medium heat in a large fry pan. Add the garlic and cook for 1 to 2 minutes, stirring occasionally. Add the tomatoes to the pan and cook for 4 minutes or until soft and jammy.
Add the cream, chicken stock, orzo and a generous amount of salt and pepper and stir. Bring to a boil, then reduce the heat to low and cook on a low simmer for 5 to 8 minutes, or until the orzo is plump and cooked and 80% of the liquid has been absorbed. Add a little more chicken stock if needed.
Take off the heat and stir through the basil, lemon juice and zest, and Pecorino Romano.
Serve immediately with Burrata, chilli flakes and an extra sprinkling of basil leaves.
