Prep the zucchini: Spiralize the zucchini into zoodles.
If you don’t have a spiralizer, use a julienne peeler or buy pre-spiralized. Spread on a tray, sprinkle lightly with salt, and let them sit for 10–15 minutes to draw out moisture. Pat dry with paper towels.
Pat the shrimp dry: Moisture is the enemy of a good sear.
Blot the shrimp with paper towels and season with salt and pepper.
Heat the pan: Set a large skillet over medium-high heat. Add 1 tablespoon olive oil and 1 tablespoon butter.
Cook the shrimp: Add shrimp in a single layer. Cook 1–2 minutes per side, just until pink and opaque.
Transfer to a plate. Don’t overcook—shrimp will finish in the sauce later.
Build the sauce: Lower heat to medium. Add the remaining olive oil and 2 tablespoons butter.
Stir in garlic and red pepper flakes. Cook 30–60 seconds until fragrant, not browned.
Deglaze: Pour in the white wine (or broth). Scrape the pan to release any browned bits.
Simmer 1–2 minutes to reduce slightly.
Add lemon: Stir in lemon zest and 2 tablespoons lemon juice. Taste and adjust—add more lemon if you like it brighter.
Toss in shrimp: Return shrimp to the pan with any juices. Warm through for 30 seconds.
Cook the zoodles: Add the zoodles and toss with tongs.
Cook 1–3 minutes, just until tender-crisp. Do not overcook or they’ll release too much water.
Finish: Remove from heat. Stir in parsley and Parmesan. Taste and adjust salt, pepper, and lemon.
Serve immediately: Plate with extra Parmesan, parsley, and a drizzle of olive oil if you like.
Add a few lemon wedges on the side.
