Stuffed Zucchini (Zapallitos Rellenos): A Taste of Uruguay

The scent of my abuela’s kitchen always held a certain magic, a symphony of aromas that transported me back to summer afternoons in Montevideo. While her asado was legendary, it was her zapallitos rellenos that truly stole my heart. Each bite of those tender zucchini boats, brimming with savory breadcrumbs and herbs, felt like a warm hug from home, a reminder of family gatherings and shared laughter around a sun-drenched table. This recipe is my humble attempt to recreate that magic, to bring a little piece of Uruguay to your kitchen.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 55 minutes
• Total Time: 1 hour 15 minutes
• Servings: 4-6
• Dietary Type: Vegetarian

Ingredients

• 2-3 medium zucchini (courgettes)
• 2 tablespoons olive oil
• ½ medium onion, finely chopped
• ¾ cup breadcrumbs, preferably fresh
• ½ cup milk
• 1 egg, beaten
• Salt and pepper, to taste
• ¼ cup breadcrumbs, preferably fresh
• 2 tablespoons butter, melted

Equipment Needed

• Baking sheet
• Large skillet
• Mixing bowl
• Knife
• Spoon

Instructions

1. Begin by preparing the zucchini. Preheat your oven to 375 degrees F (190 degrees C). Place the whole zucchini on a baking sheet and bake for 30 minutes, until they are slightly soft but not mushy. This par-baking ensures they’re tender in the final dish. Remove from the oven and set aside to cool slightly.
2. While the zucchini are baking, prepare the filling. Heat the olive oil in a skillet over moderate heat. Add the finely chopped onion and sauté until golden brown and softened, about 5-7 minutes. This step is crucial for developing a deep, savory flavor base for the filling.
3. In a mixing bowl, combine ¾ cup of the breadcrumbs, the milk, the beaten egg, the cooked onion, salt, and pepper. Stir well to combine all the ingredients thoroughly. The mixture should be moist but not soggy. Adjust seasoning as needed.
4. Once the zucchini are cool enough to handle, slice them in half lengthwise. Using a spoon, carefully scoop out the pulp from each half, leaving a shell about ¼ inch thick. Be gentle to avoid tearing the zucchini.
5. Chop the scooped-out zucchini pulp coarsely and add it to the breadcrumb mixture in the bowl. Stir to incorporate the pulp evenly throughout the filling. This adds moisture and more zucchini flavor to the filling.
6. Now, fill each zucchini shell generously with the breadcrumb mixture, mounding it slightly. Ensure that each zucchini boat is packed with the savory filling.
7. Prepare the topping. In a small bowl, combine the remaining ¼ cup of breadcrumbs with the melted butter. Mix until the breadcrumbs are evenly coated with butter.
8. Sprinkle the breadcrumb topping evenly over the filled zucchini. This will create a golden-brown, crispy crust during the final bake.
9. Return the filled zucchini to the preheated 375 degree F (190 degrees C) oven and bake for an additional 25 minutes, or until the topping is golden brown and the filling is heated through. The filling should be firm to the touch.
10. Remove from oven and let sit for 5 minutes before serving.

Expert Tips & Tricks

• Breadcrumb Perfection: Using fresh breadcrumbs, especially those made from crusty bread, gives the filling a wonderful texture and flavor. If you don’t have fresh breadcrumbs, you can lightly toast store-bought breadcrumbs in a dry skillet to enhance their flavor.
• Onion Caramelization: Take your time when sautéing the onion. Allowing it to slowly caramelize adds a depth of sweetness and complexity to the filling.
• Pulp Moisture: If your zucchini pulp seems particularly watery after chopping, you can squeeze out some of the excess moisture using a clean kitchen towel. This will prevent the filling from becoming too soggy.
• Egg Substitute: If you are looking for a vegetarian alternative, you can use a flax egg. Mix 1 tablespoon of ground flaxseed with 3 tablespoons of water and let it sit for 5 minutes to thicken before adding it to the breadcrumb mixture.
• Spice it Up: Feel free to add a pinch of red pepper flakes to the filling for a touch of heat, or some grated Parmesan cheese for extra flavor.

Serving & Storage Suggestions

Zapallitos rellenos are best served warm, straight from the oven. They make a fantastic vegetarian main course, or a delicious side dish to grilled meats or fish. Garnish with a sprinkle of fresh parsley or a dollop of sour cream for an extra touch of flavor.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, bake in a preheated 350 degree F (175 degrees C) oven until warmed through, or microwave until heated. The topping may lose some of its crispness upon reheating.

Freezing is not recommended, as the zucchini can become watery upon thawing.
