One-Pan Keto Shrimp and Asparagus

Heat avocado oil and butter together in a skillet over medium heat. Add garlic and cook until lightly browned, 1 to 3 minutes. Place shrimp into one side of the pan; season with salt and red pepper flakes. Add asparagus to the other side of the pan and season with salt and black pepper. Flip shrimp after about 2 minutes and roll asparagus over. Squeeze lemon juice on top of shrimp and continue cooking about 3 minutes more. Gently sprinkle Parmesan cheese over shrimp. Transfer to a plate and pour pan juices over shrimp.
