Keto Sheet Pan Stuffed Avocado Seafood Boats

There are some recipes that surprise you with how simple they are, yet they taste like something you’d order at a fancy coastal restaurant. That’s exactly how I felt when I first made these Keto Sheet Pan Stuffed Avocado Seafood Boats.

A close friend recommended this recipe to me a few months ago after she started following a low-carb lifestyle. She couldn’t stop talking about how creamy, satisfying, and flavorful it was. I’ll admit, I was a little skeptical at first. Avocados stuffed with seafood and baked on a sheet pan sounded interesting, but I wasn’t sure how my family would react.

Last weekend, I decided to give it a try for a casual family dinner. The combination of creamy avocado, tender shrimp, sweet crab meat, and melted cheese sounded too good to pass up. As the seafood mixture baked in the oven, the kitchen filled with an irresistible aroma. My family gathered around the kitchen asking what was cooking, and by the time dinner was served, everyone was excited to dig in.

The result was incredible. The avocados became warm and buttery, while the seafood filling turned rich, creamy, and cheesy. Everyone loved it, and there wasn’t a single stuffed avocado left on the tray. Since then, this has become one of my favorite recipes to make when I want something comforting but healthy. It’s perfect for weekends, special occasions, or even those stressful days when I need a meal that feels a little indulgent without completely derailing my goals.

If you’re looking for a keto-friendly meal that’s packed with healthy fats, protein, and flavor, these Stuffed Avocado Seafood Boats are definitely worth trying.

• 4 ounces (115g) lump crab meat
• ¼ cup mayonnaise
• 2 tablespoons cream cheese, softened
• 1 tablespoon fresh lemon juice
• 1 teaspoon Dijon mustard
• 1 garlic clove, finely minced
• ½ cup shredded mozzarella cheese
• 2 tablespoons grated Parmesan cheese
• 2 tablespoons fresh parsley, chopped
• Salt, to taste
• Black pepper, to taste
• ½ teaspoon paprika

Optional Toppings

Kitchen Equipment Needed

• Sheet pan
• Mixing bowl
• Spoon
• Knife
• Cutting board
• Measuring cups and spoons

Step-by-Step Instructions

Step 1: Prepare the Oven

Preheat your oven to 400°F (200°C).

Line a sheet pan with parchment paper or lightly grease it.

Step 2: Prepare the Avocados

Slice the avocados in half lengthwise and remove the pits.

Using a spoon, carefully scoop out a small amount of avocado flesh from the center of each half.

Don’t discard the removed avocado. Chop it finely and save it for the filling.

This creates extra room for the seafood mixture.

Step 3: Make the Seafood Filling

In a large mixing bowl, combine:

• Chopped shrimp
• Crab meat
• Reserved avocado
• Mayonnaise
• Cream cheese
• Lemon juice
• Dijon mustard
• Garlic
• Parsley
• Salt
• Pepper

Mix until fully combined.

Add half of the mozzarella cheese and stir again.

Step 4: Fill the Avocados

Place the avocado halves on the prepared sheet pan.

Divide the seafood mixture evenly among all avocado halves.

Gently press the filling into each avocado boat.

Step 5: Add the Cheese

Sprinkle the remaining mozzarella cheese over the top.

Finish with Parmesan cheese and paprika.

Step 6: Bake

Place the sheet pan in the oven.

Bake for 12–15 minutes.

The cheese should be melted, bubbly, and lightly golden.

Step 7: Garnish and Serve

Remove from the oven.

Top with fresh parsley, extra Parmesan, and a squeeze of lemon juice if desired.

Serve immediately while warm.

Chef’s Tips

Choose Perfect Avocados

Use ripe avocados that yield slightly when gently pressed.

Overripe avocados may become too soft during baking.

Use Fresh Seafood

Fresh shrimp and crab produce the best flavor.

However, high-quality frozen seafood works wonderfully too.

Make It Spicy

Add diced jalapeños or red pepper flakes to the filling.

Add Extra Protein

Mix in cooked lobster, scallops, or salmon for a seafood feast.

Don’t Overbake

Avocados are best when warmed through but not cooked excessively.

Variations

Cajun Seafood Boats

Add Cajun seasoning and a little hot sauce.

Garlic Butter Version

Mix melted garlic butter into the filling.

Mediterranean Style

Add feta cheese, olives, and fresh dill.

Bacon Seafood Boats

Top with crispy crumbled bacon before serving.

Storage Instructions

Refrigerator

Store leftovers in an airtight container for up to 2 days.

Freezer

Freezing is not recommended because avocados can become watery after thawing.

Reheating

Warm gently in the oven at 350°F (175°C) for 8–10 minutes.

Avoid microwaving if possible.
