Equipment

  • Mixing bowl
  • Small Pan
  • Oven-Safe Dish

Ingredients
  

  • 2.5 cups chopped spinach If using frozen, make sure to thaw it completely and squeeze out as much water as you possibly can!
  • 0.5 lb medium sized raw shrimp Peeled and deveined
  • 8 oz crab lump crab meat or imitation crab
  • 0.25 cup cream cheese Softened
  • 0.25 cup sour cream
  • 1 tbsp mayonnaise
  • 1 tbsp green onion Chopped
  • 0.5 tsp Old Bay Seasoning
  • 0.25 tsp lemon pepper seasoning
  • 0.5 cup mozzarella cheese
  • 1 cup Muenster cheese divided: ½ cup for the dip, ½ cup for topping
  • 0.25 tsp pepper Freshly ground is always best!
  • 0.33 cup onion small diced
  • 1 tsp garlic paste or minced garlic
  • 1 tsp cooking oil

Instructions
 

  • Step 1: Preheat your oven to a cozy 375°F.
  • Step 2: In a medium to large mixing bowl, combine your chopped spinach (remember to squeeze out all that excess water if it was frozen!), the softened cream cheese, sour cream, mayonnaise, chopped green onions, Old Bay seasoning, lemon pepper seasoning, mozzarella cheese, and half a cup of your Muenster cheese. Don't forget a little sprinkle of pepper! Mix everything thoroughly until it’s all wonderfully combined and super creamy. Taste and adjust any seasonings if needed. Set this mixture aside.
  • Step 3: In a small pan, heat your cooking oil over medium heat. Add your diced onion and garlic paste (or minced garlic). Sauté these until they become translucent and beautifully soft – this usually only takes a few minutes.
  • Step 4: Add your medium-sized, peeled, and deveined shrimp to the pan with the onions and garlic. Cook them for just about one minute, or until they just begin to turn pink. Do not overcook them here, as they'll continue cooking in the oven later.
  • Step 5: As soon as those shrimp are just blushing pink, remove the pan from the heat to stop the cooking process.
  • Step 6: Carefully combine the cooked shrimp, onion, and garlic mixture with your prepared creamed spinach mixture. Give it a gentle stir to make sure the seafood is evenly distributed throughout the creamy base.
  • Step 7: Transfer your glorious seafood dip into an oven-safe dish (a shallow baking dish or even a cast iron skillet works wonderfully here). Then, sprinkle the remaining ½ cup of Muenster cheese all over the top.
  • Step 8: Pop your dish into the preheated oven and bake for 20 minutes. It's ready when the dip is heated through and the shrimp are perfectly cooked, and the edges might even be starting to bubble!
  • Step 9: For that ultimate golden, bubbly top, change your oven setting to broil. Broil the dip for just 30 seconds to 1 minute, keeping a very close eye on it, until the cheese is beautifully golden brown and actively bubbling. Once it's perfect, carefully remove it from the oven, let it cool for just a minute or two, and then serve immediately.

Notes

Tips for Success: If using frozen spinach, you must squeeze out every single drop of water after thawing to prevent a runny dip. When sautéing shrimp, only cook them until they just barely turn pink to prevent them from becoming tough. Freshly shredded cheese melts more smoothly. Always taste your dip mixture before baking and adjust seasonings to your preference.
Make Ahead: You can assemble the entire dip (steps 1-7) and cover it tightly, then refrigerate for up to 24 hours. Let it sit at room temperature for about 15-20 minutes before baking, and you might need to add an extra 5-10 minutes to the baking time.
Substitutions & Additions: Feel free to swap out some shrimp or crab for cooked lobster meat, bay scallops, or a flaky white fish. Add Parmesan, white cheddar, or Monterey Jack cheese. Stir in chopped artichoke hearts, finely diced red bell pepper, or sautéed mushrooms. For a kick, add cayenne pepper, hot sauce, or finely diced jalapeño.
Serving Suggestions: This dip is amazing with classic tortilla chips, crusty baguette slices, pita chips, celery sticks, carrot sticks, or bell pepper strips.
Storage: Store any leftover dip in an airtight container in the refrigerator for up to 3-4 days. Reheat gently in the microwave in short bursts, stirring occasionally, or in the oven at 300°F until warmed through (add a tiny splash of milk or cream if dry, and cover loosely with foil). Freezing is not recommended as the creamy base and seafood can sometimes separate or change texture.
