In a medium bowl, toss the shrimp with olive oil, chili powder, cumin, garlic powder, salt, and pepper. Ensure the shrimp are evenly coated.
Heat a large skillet over medium-high heat. Add the seasoned shrimp and cook for 2-3 minutes per side, or until pink and cooked through.
While the shrimp cooks, prepare the lime crema. In a small bowl, whisk together the sour cream, lime juice, minced garlic, and a pinch of salt until smooth.
Warm the tortillas according to package directions.
Assemble the tacos by filling each warm tortilla with a portion of the cooked shrimp. Drizzle with lime crema and top with shredded cabbage, red onion, and cilantro.
Serve immediately with lime wedges on the side.
Notes
These shrimp tacos are perfect for a quick weeknight meal or a casual gathering. Adjust the spice level by adding more or less chili powder.
