Shrimp Scampi Zoodles

Preheat oven to 400 degrees F. Insert flat end of one zucchini into a spiralizer and turn to make noodles; repeat with remaining zucchini. Cut the noodles to 7" lengths and place in a colander, sprinkle with 1 tablespoon salt and gently mix to coated noodles. Set aside and let noodles drain over a dish. In a medium bowl season shrimp with salt and pepper. Place shrimp in an even layer on a rimmed sheet pan. Roast for 8 minutes. In a large skillet set over medium heat add 2 tablespoons olive oil, garlic, onions, 1/2 teaspoon salt, 1/4 teaspoon pepper, and red pepper flakes; cook until softened, 2 minutes. Heat to medium-high; add wine, lemon zest, and lemon juice and simmer until sauce has reduced, 3 to 4 minutes. Drain zucchini noodles and pat dry with paper towels. Add to sauce and toss until warmed through. Reduce heat to low and stir cold butter into the sauce; add cooked shrimp. Toss with parsley and garnish with lemon wheels. Serve immediately.
