Preheat the oven to 375°F. Line a baking sheet with parchment paper and set aside.
Slice the top and bottom off of 3 zucchinis. Slice each zucchini in half lengthwise then scoop out the inside pulp with a spoon leaving a bit for stability. Chop the zucchini pulp into small bite-size chunks.
Heat a frying pan over medium high heat. Add 1 Tbsp olive oil, ½ cup chopped onion, and 4 minced garlic cloves. Saute for 1-2 minutes, until onion turns translucent.
Add the chopped zucchini pulp and cook another 1-2 minutes until softened.
Add the cooked zucchini mixture to a strainer to remove any excess liquid. To remove even more moisture you can squeeze it through a kitchen towel (optional).
Now add the cooked zucchini mixture, 6 oz crab meat, ½ cup shredded mozzarella, ½ cup feta cheese, 1 beaten egg, 1 Tbsp all purpose flour, 1 Tbsp chopped parsley, 1 Tbsp chopped fresh dill, ½ tsp salt and ¼ tsp ground black pepper to a large bowl. Mix everything together.
Scoop the mixture onto the sliced zucchini. Top with the last half of shredded mozzarella, and more fresh dill. Season with salt and pepper.
Bake for 30 minutes, until the tops begin to slightly turn golden brown. Remove from heat and let sit 5 minutes before serving.
Recipe Notes:
Zucchini produces a lot of excess liquid once cooked. I prefer to add it to a strainer and then blot it with paper towel to remove as much as possible.
Use a spoon to scoop out the zucchini flesh. Scoop out as much as you can to make the skin about ½” thick.
If you have extra filling, save leftovers for lunch in a wrap or sandwich. Extra filling can be sauteed and stored in the fridge.
Add a bit of extra mozzarella, fresh dill and ground pepper on top just before baking. The cheese will turn golden brown as you bake.
Leftovers can be stored in an airtight container in the fridge for 3-4 days. Reheat in the oven or in microwave until warmed through.
