In a large mixing bowl, stir together the sour cream, mayonnaise, and Knorr Vegetable Recipe Mix until smooth and evenly seasoned with no dry pockets.
Add a hint of fresh lemon zest and a pinch of garlic powder, then mix again until the base smells bright and savory.
Prep and Add the Spinach
Cook frozen spinach according to package directions, then squeeze out excess water until it feels very dry.
Add the drained spinach into the mixing bowl with the creamy base.
Add Crunch and Freshness
Drain and dice the water chestnuts, then slice the green onions, and stir both into the mayo mixture. Keep the water chestnuts finely chopped so you get consistent crunch in every scoop.
Chill for Best Flavor
Mix everything really well until the dip looks cohesive and creamy, then cover the bowl tightly with plastic wrap and refrigerate for 2 hours before serving.
Notes
For the thickest texture and most developed flavor, chill overnight (12 to 24 hours). Store in an airtight container and enjoy within 3 to 4 days. Freezing is not recommended because sour cream and mayonnaise can separate.Nutrition information is estimated based on common ingredients and serving sizes and may vary.
