Using a spiralizer or julienne peeler, create noodles from the summer squash.
Spread them on a layer of paper towels, sprinkle lightly with salt, and let them sit for 20-30 minutes to draw out excess moisture.
Pat dry with more paper towels.
In a large skillet or pan, melt the butter over medium heat.
Add the minced garlic and red pepper flakes, and cook for about 30-60 seconds until fragrant, being careful not to burn the garlic.
Pour in the chicken broth and lemon juice, bringing the mixture to a gentle simmer.
Add the shrimp in a single layer and cook for 2-3 minutes, flipping once, until they are pink and opaque.
Season with salt and pepper to taste.
Add the prepared summer squash noodles and fresh parsley to the skillet.
Toss gently for 1-2 minutes to heat the noodles through and coat everything in the sauce.
Serve immediately, garnished with extra parsley or a sprinkle of Parmesan cheese if desired.
Don't skip salting the zucchini noodles. This crucial step prevents a watery sauce and ensures your 'zoodles' have the perfect al dente texture.
Add halved cherry tomatoes or a handful of fresh spinach along with the shrimp for extra nutrients and a pop of color.
