Equipment You’ll Need
- Medium skillet
- Mixing bowls
- Spatula and whisk
- Baking dish (8×8 or similar)
- Oven preheated to 375°F (190°C)
Step-by-Step Instructions
Step 1: Cook the Spinach
- Heat olive oil in a skillet over medium heat.
- Add minced garlic and sauté for about one minute until fragrant.
- Stir in the chopped spinach and cook until wilted, about 2–3 minutes.
- Drain any excess moisture and set aside to cool slightly.
Step 2: Make the Creamy Base
- In a mixing bowl, beat the cream cheese until smooth.
- Add mayonnaise, sour cream, Dijon mustard, lemon juice, and seasonings.
- Whisk until well blended into a creamy, thick mixture.
Step 3: Incorporate Seafood and Spinach
- Fold in the chopped shrimp and crab meat.
- Stir in the cooked spinach until evenly distributed throughout the dip.
Step 4: Add Cheese
- Mix in the mozzarella, Parmesan, and cheddar (if using).
- Combine well so the cheese is spread throughout the mixture.
Step 5: Assemble the Dip
- Transfer mixture to a lightly greased baking dish.
- Smooth out the top and sprinkle with extra mozzarella.
Step 6: Bake
- Bake at 375°F (190°C) for 25–30 minutes.

Step 7: Serve Hot
- Remove from the oven and garnish with chopped parsley.
- Serve immediately with chips, bread, or vegetable sticks.
Tips for Success
- Drain Spinach Thoroughly – Any extra water will make the dip runny.
- Use Freshly Shredded Cheese – Pre-shredded cheese often has anti-caking agents that prevent smooth melting.
- Chop Seafood Small – Smaller pieces distribute evenly and are easier to scoop.
- Add Heat if Desired – A dash of cayenne pepper or crushed red pepper flakes can give it a spicy twist.
- Broil at the End – For an extra bubbly top, place under the broiler for 2–3 minutes before serving.
Flavor Variations
- Seafood Choices – Swap shrimp and crab for scallops, lobster, or a seafood medley.
- Cheese Mix – Try Gruyère, Monterey Jack, or fontina for a different flavor profile.
- Spicy Version – Add diced jalapeños, hot sauce, or pepper jack cheese.
- Extra Creamy – Mix in a splash of heavy cream or more sour cream.
- Lighter Option – Use Greek yogurt instead of sour cream and reduced-fat cream cheese.

- With tortilla chips or pita chips for classic dipping.
- Spread on toasted baguette slices for a more elegant appetizer.
