Begin by spiralizing the zucchini to create zucchini noodles (zoodles). Set aside.
In a large skillet, heat 2 tablespoons of olive oil and 1 tablespoon of butter over medium heat.
Once the oil and butter are sizzling, add minced garlic and red pepper flakes to the skillet. Sauté for about 1 minute until the garlic is fragrant but not burned.
Add the shrimp to the skillet, seasoning with salt and pepper. Cook for about 2-3 minutes on each side until the shrimp turn pink and opaque. Remove the shrimp from the skillet and set aside.
In the same skillet, add the spiralized zucchini noodles and toss them in the remaining 1 tablespoon of olive oil. Sauté the zoodles for about 2-3 minutes, just until they are slightly tender but not mushy.
Return the shrimp to the skillet with the zucchini, and add the lemon juice and lemon zest. Toss everything together and cook for an additional minute to heat through.
Taste and adjust seasoning with more salt, pepper, or red pepper flakes if desired.
Remove from heat and garnish with fresh chopped parsley before serving.
Notes
Serve in bowls garnished with lemon wedges and extra parsley.
