Prepare Spinach - Place frozen spinach in a bowl and defrost at medium power for about 2 minutes. Stir to distribute any heat. The leaves should be thawed but still slightly icy and not warmed up. Use your hands to squeeze the excess water from the defrosted spinach.
Combine Ingredients - In a medium bowl, mix together drained spinach, sour cream, mayonnaise, water chestnuts, green onions, dill, garlic powder, onion powder, salt, bell pepper, and carrots until combined.
To Serve - The dip pairs well with sliced baguettes, pita chips, crackers, or vegetables.
