Ensure shrimp is thawed and patted dry to sauté properly without steaming., Cook shrimp just until opaque to maintain tenderness and juiciness., Whisk cream and cream cheese over medium heat until smooth and bubbling to avoid lumps., Adjust sauce thickness by adding water or cream as needed., Use a cast iron or heavy skillet for even heat and better flavor., Stir spinach often during cooking to prevent clumping and ensure even wilting., For make-ahead meals, prepare sauce first; add shrimp and spinach freshly before serving for best texture., Variations include serving over pasta, zucchini noodles, or rice; substituting half the spinach with baby kale or Swiss chard; using fresh garlic instead of garlic powder; swapping cream cheese with mascarpone, ricotta, or coconut cream; and adding lemon juice, red pepper flakes, or Parmesan cheese to enhance flavor., Store leftovers in an airtight container in the fridge for up to 2-3 days; reheat gently on low heat with splash of water or cream to maintain sauce consistency., Avoid freezing the fully cooked dish as cream sauces may break and shrimp texture may degrade. Freeze raw shrimp and sauce separately if prepping ahead.
