Ingredients You’ll Need

This recipe uses simple ingredients that you probably already have in your keto kitchen. Here’s what you need:

Main Ingredients:

• 8 oz cream cheese (softened) – This makes the casserole super creamy.
• 1 cup shredded mozzarella cheese – Melts beautifully and adds a mild flavor.
• ½ cup shredded cheddar cheese – Adds a bit of sharpness.
• ½ cup sour cream – Gives the dish extra richness.
• 2 tbsp mayonnaise – Helps create that signature rangoon taste.
• 1 tsp Worcestershire sauce – Adds a deep, savory flavor.
• 1 tsp soy sauce (or coconut aminos for lower carbs) – Brings in a bit of umami.
• 1 tsp garlic powder – A must-have for that classic flavor.
• ½ tsp onion powder – Enhances the flavor without the carbs of real onions.
• ½ tsp salt – Adjust to taste.
• ½ tsp black pepper – Adds a little kick.
• 1 tbsp green onions (chopped, for garnish) – Optional, but highly recommended.
• 1 lb lump crab meat or canned crab (drained well) – Fresh crab gives the best taste, but canned works too.

Optional Keto-Friendly Toppings:

• ½ cup crushed pork rinds – If you want some crunch on top.
• 1 tbsp melted butter – Helps crisp up the topping.

Step-by-Step Instructions

Making this casserole is as easy as mixing everything together and baking. Follow these simple steps:

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). Grease a 9×9-inch baking dish with butter or non-stick spray.

Step 2: Mix the Creamy Base

In a large mixing bowl, combine the softened cream cheese, sour cream, mayonnaise, Worcestershire sauce, soy sauce, garlic powder, onion powder, salt, and pepper. Stir until everything is well combined and smooth.

Step 3: Add the Cheese and Crab

Gently fold in the shredded mozzarella, shredded cheddar, and crab meat. Try not to overmix, so the crab stays in nice chunks.

Step 4: Transfer to Baking Dish

Spread the mixture evenly into the prepared baking dish.

Step 5: Add a Crunchy Topping (Optional)

If you want some extra texture, mix the crushed pork rinds with melted butter and sprinkle them on top before baking.

Step 6: Bake

Bake uncovered for 20-25 minutes, or until the casserole is hot and bubbly with a lightly golden top.

Step 7: Garnish and Serve

Remove from the oven and let it sit for 5 minutes before serving. Sprinkle with chopped green onions for extra flavor and color.

What to Serve with Keto Crab Rangoon Casserole

This casserole is delicious on its own, but if you want to make a full meal out of it, here are some ideas:

• Steamed or roasted veggies – Broccoli, cauliflower, or green beans go great with this dish.
• Keto crackers or cheese crisps – Use them to scoop up that creamy goodness.
• A simple side salad – A fresh green salad with a light dressing balances out the richness.

Tips for the Best Keto Crab Rangoon Casserole

1. Use Real Crab for the Best Flavor

While canned crab works fine, lump crab meat gives the best taste and texture. If you’re using canned, make sure to drain it well to avoid a watery casserole.

2. Don’t Skip the Cream Cheese

The cream cheese is the star of the show. It gives the casserole its creamy, slightly tangy base, just like the filling in traditional crab rangoons.

3. Adjust the Seasonings to Your Taste

Some people like a little extra garlic, while others prefer a touch of spice. Feel free to add a pinch of cayenne pepper or red pepper flakes if you want some heat.

4. Make It Ahead for Easy Meal Prep

This casserole stores well in the fridge for up to 4 days. Just reheat in the oven at 350°F (175°C) for about 10 minutes or until warm.

5. Freezing Tips

You can freeze this dish before or after baking. If freezing before, just cover tightly with foil and bake when ready. If freezing after, reheat in the oven to keep the texture nice and creamy.

Variations & Add-Ins

Want to switch things up? Here are some fun ways to customize your casserole:

1. Spicy Kick

• Add ½ tsp crushed red pepper flakes or a few dashes of hot sauce to the mix.

2. Extra Cheesy

• Mix in a little parmesan cheese for an extra cheesy bite.

3. Asian-Inspired Twist

• Add a teaspoon of sesame oil and a splash of rice vinegar to bring out more traditional rangoon flavors.

4. More Crunch

• Instead of pork rinds, try topping with shredded parmesan for a crispy, cheesy crust.
