Cook the whole wheat linguine according to package directions until al dente, drain, and set aside.
Use a spiralizer to create zucchini noodles and pat them dry with a paper towel to remove excess moisture.
In a large skillet over medium-high heat, add the extra virgin olive oil and ghee until melted and shimmering.
Season the shrimp with sea salt and black pepper, then add them to the skillet in a single layer.
Sear the shrimp for 2 minutes per side until they are pink and opaque, then remove them from the pan and set aside.
In the same skillet, add the minced garlic and red pepper flakes, sautéing for 1 minute until the aroma is fragrant.
Stir in the lemon juice and lemon zest, scraping the bottom of the pan to release any browned bits.
Add the cooked linguine and zucchini noodles to the skillet, tossing for 1-2 minutes until the zucchini is slightly softened.
Return the shrimp to the pan, add the fresh parsley, and toss everything together to coat in the garlic butter sauce.
