For a keto version of classic Italian shrimp scampi, we wanted to find a good substitute for wheat-based pasta and retain all of the rich garlic and seafood flavors of the original recipe. As we have in other keto pasta recipes, we swapped in long strands of spiralized zucchini; their mild flavor allowed the shrimp and garlic to be the stars of the dish, and their texture closely resembled that of conventional pasta. For the sauce, we first infused our cooking oil with minced garlic, red pepper flakes, and thyme.
We stirred in clam juice to reinforce the seafood flavor before cooking the shrimp in the liquid and setting it aside. Reducing the sauce before whisking in butter gave it a classic, rich finish. The sauce was deliciously garlicky but the first time we stirred zucchini noodles directly into it, their moisture diluted the flavor of the sauce. So we roasted the spiralized zucchini first. Once our sauce was thick, we tossed the shrimp and roasted noodles into it to coat and serve. If possible, use smaller, in-season zucchini, which have thinner skins and fewer seeds. We prefer to spiralize our own zucchini, but you can substitute 2 pounds of store-bought spiralized zucchini, though they tend to be drier and less flavorful. Avoid buying large zucchini, which have thicker skins and more seeds.

- Using spiralizer, cut zucchini into ⅛-inch-thick noodles, then cut noodles into 12-inch lengths. (You should have 2 pounds zucchini noodles after spiralizing; reserve any extra noodles for another use.)
- Adjust oven rack to middle position and heat oven to 375 degrees. Toss zucchini noodles with 1 tablespoon oil and salt on rimmed baking sheet and spread into even layer. Roast until zucchini is tender, 20 to 25 minutes. Transfer zucchini to colander and shake to remove any excess liquid.
- Meanwhile, heat remaining 2 tablespoons oil, garlic, pepper flakes, and thyme in 12-inch nonstick skillet over medium heat, stirring occasionally, until garlic is fragrant and just beginning to brown at edges, 3 to 5 minutes. Add clam juice and bring to simmer. Add shrimp, cover, and cook, stirring occasionally, until just opaque, 3 to 5 minutes. Off heat, transfer shrimp to bowl using slotted spoon and cover to keep warm.
- Return sauce to simmer over medium-high heat and cook until reduced to ½ cup, about 5 minutes. Off heat, whisk in butter, 1 piece at a time, until combined. Whisk in lemon juice and parsley and season with salt and pepper to taste. Add shrimp and any accumulated juices and zucchini and gently toss to coat. Serve.
