Begin by preparing the zucchini: Using a spiralizer, create zoodles from the zucchinis. Optionally, lightly sprinkle with salt and let sit while you prepare the shrimp; this helps to draw out excess moisture.
Heat a large skillet over medium heat and add 2 tablespoons of olive oil.
Once the oil is hot, add the minced garlic and sauté for about 1 minute until fragrant, being careful not to burn it.
Add the raw shrimp to the skillet, season with salt, pepper, and red pepper flakes (if using). Cook until they turn pink and opaque, about 2-3 minutes per side, then remove from the skillet and set aside.
In the same skillet, reduce heat to low and add the butter; allow it to melt. Once melted, stir in the lemon juice.
Add the zoodles to the skillet, tossing gently in the garlic butter sauce for about 2-3 minutes until just tender.
Return the cooked shrimp to the skillet and combine with the zoodles, cooking for an additional 1-2 minutes to warm through.
Adjust seasoning with more salt and pepper to taste if necessary.
Remove from heat and garnish with chopped fresh parsley before serving.
