Warm the broth in a saucepan and keep it at a low simmer.
In a large pot, cook the diced onion in the oil and 1 tbsp butter 4 minutes, then add the ham and garlic for 2 minutes.
Add the rice and stir 1-2 minutes until the edges look translucent.
Add the broth a ladle at a time, stirring often and waiting until each addition is mostly absorbed, 18-20 minutes total, until creamy and just tender.
Stir in the peas for the last 3 minutes.
Off the heat, stir in the parmesan, remaining butter and the lemon zest; season to taste and serve right away.
