Spiralize the zucchini and pat the noodles dry with a clean towel — dry noodles stay firm instead of going watery.
Heat 1 tbsp olive oil in a large skillet over medium-high heat. Season the shrimp with salt and pepper, then cook 2 minutes per side until pink and opaque. Remove to a plate.
Lower the heat to medium. Add the remaining olive oil and the butter, then the garlic and red pepper flakes. Cook 30 seconds until fragrant — do not let the garlic brown.
Add the zucchini noodles and toss for 2 minutes, just until warmed through and slightly softened.
Return the shrimp to the pan, squeeze in the lemon juice, and toss everything together.
Serve straight away, topped with parmesan and fresh parsley.
Notes
Pat zucchini noodles dry before cooking. Do not overcook the shrimp. Best eaten fresh; leftovers keep 1 day refrigerated.
