Preheat and Pierce: Heat your oven to 400°F. Poke the spaghetti squash with a fork about 10 times to help it cook evenly. Then, bake it in the oven for around an hour.
In a large skillet, melt 3 tablespoons of ghee over medium-high heat. Add 4 cloves of minced garlic and ¼ teaspoon of red pepper flakes. Cook for about 30 seconds until fragrant. Add 1 pound of shrimp and cook for 2-3 minutes per side. Sprinkle with 1 tablespoon of lemon juice, ½ teaspoon of lemon zest, and 2 tablespoons of chopped parsley.
Once the squash is roasted, let it cool. Then, cut it open, remove the seeds, and scrape out the strands with a fork. Top the squash with the garlic shrimp mixture.
