01 - Pat the shrimp dry with paper towels and season lightly with salt and black pepper.
02 - Heat 1 tablespoon olive oil and 1 tablespoon butter in a large skillet over medium-high heat. Add the shrimp in a single layer and cook for 2 minutes per side, or until just opaque and pink. Remove shrimp to a plate and set aside.
03 - In the same skillet, add the remaining olive oil and butter. Sauté the shallot and garlic for 1–2 minutes until fragrant but not browned.
04 - Pour in the heavy cream, bring to a gentle simmer, and stir in the Parmesan cheese until melted. Season with salt, black pepper, and red pepper flakes if using.
05 - Add the zucchini noodles and toss gently in the sauce for 1–2 minutes, just until slightly tender but still crisp.
06 - Return the shrimp to the skillet and combine with the noodles and sauce. Cook for an additional minute to heat through. Remove from heat, garnish with fresh parsley, and serve immediately with lemon wedges.
