Warm the vegetable stock in a small saucepan and keep it at a low simmer on the back burner.
Heat the olive oil and half the butter in a wide saute pan over medium heat. Add the shallot and cook for 3 minutes until soft and translucent.
Add the rice and toast for 2 minutes, stirring, until the edges look glassy.
Pour in the wine and stir until it's fully absorbed, about 1 minute.
Stir in three quarters of the diced strawberries, reserving the rest for later. Cook for 1 minute until they start to break down.
Add warm stock one ladle at a time, stirring often and waiting until each addition is absorbed before adding the next. This takes about 17 to 18 minutes total.
Taste the rice at 17 minutes. It should be al dente with a slight bite in the center, not chalky and not mushy.
Remove the pan from the heat. Stir in the remaining butter and the parmesan until the risotto turns glossy and loosens slightly, about 1 minute.
Fold in the reserved raw strawberries. Season with salt and black pepper, then plate immediately in shallow bowls.
