Uruguayan Stuffed Zucchini (Zapallitos Rellenos): A Taste of Home

The scent of sauteed onions and warm breadcrumbs always transports me back to my Abuela Elena’s kitchen in Montevideo. I remember sitting at her worn wooden table, watching her deftly scoop out the zucchini pulp with a grapefruit spoon, her hands moving with the practiced grace of someone who had made this dish countless times. These zapallitos rellenos weren’t just a meal; they were a symbol of family, comfort, and the vibrant flavors of Uruguay. The aroma alone was enough to make my mouth water in anticipation. Each bite was a little piece of home, wherever I was.

Recipe Overview

• Prep Time: 25 minutes
• Cook Time: 55 minutes
• Total Time: 1 hour 20 minutes
• Servings: 4-6
• Yield: 4-6 zucchini halves
• Dietary Type: Vegetarian (easily adaptable to gluten-free and dairy-free)

Ingredients

• 2-3 medium zucchini
• 2 tablespoons olive oil
• ½ medium onion, finely chopped
• ¾ cup breadcrumbs, preferably fresh
• ½ cup milk
• 1 egg, beaten
• Salt & freshly ground black pepper
• For the topping:
  • ¼ cup breadcrumbs, preferably fresh
  • 2 tablespoons butter, melted

Equipment Needed

• Baking sheet
• Skillet
• Mixing bowl
• Knife
• Spoon or melon baller for scooping zucchini

Instructions

1. Start by preheating your oven to 375°F (190°C). This ensures the zucchini will bake evenly.
2. Wash the zucchini thoroughly and place them on a baking sheet. Bake for 30 minutes, or until they are soft but not mushy. Test their doneness by gently piercing them with a fork. If the fork slides in easily, they’re ready.
3. Remove the zucchini from the oven and set aside to cool slightly. Allowing them to cool makes them easier to handle.
4. While the zucchini are cooling, heat the olive oil in a skillet over moderate heat. Add the finely chopped onion and sauté until golden brown, about 5-7 minutes. Stir frequently to prevent burning. Caramelizing the onions adds depth of flavor to the filling.
5. In a mixing bowl, combine the breadcrumbs, milk, egg, cooked onion, salt, and pepper. Stir well to combine. The mixture should be moist but not soggy. Adjust the amount of milk if needed.
6. Once the zucchini are cool enough to handle, slice them in half lengthwise.
7. Using a spoon or melon baller, carefully scoop out the pulp from each zucchini half, leaving a shell about ¼ inch thick. Be gentle to avoid breaking the zucchini.
8. Chop the scooped-out zucchini pulp coarsely and add it to the breadcrumb mixture. Stir to combine thoroughly.
9. Generously fill each zucchini shell with the breadcrumb mixture. Pack it in firmly.
10. For the topping, combine the remaining breadcrumbs and melted butter in a small bowl. Mix until the breadcrumbs are evenly coated with butter.
11. Sprinkle the breadcrumb topping evenly over the filled zucchini halves. This will create a golden-brown and crispy crust.
12. Bake in the preheated 375°F (190°C) oven until the topping is golden brown and the zucchini is heated through, about 25 minutes. Keep an eye on the topping to prevent it from burning. If it starts to brown too quickly, cover the zucchini loosely with foil.
13. Remove from the oven and let cool for a few minutes before serving.

Expert Tips & Tricks

• Breadcrumb Perfection: Using fresh breadcrumbs, especially homemade, will result in a lighter and more flavorful filling. If you don’t have fresh breadcrumbs, you can pulse stale bread in a food processor until finely ground.
• Flavor Boost: Consider adding a pinch of nutmeg or a dash of dried oregano to the breadcrumb mixture for an extra layer of flavor.
• Preventing Soggy Zucchini: To avoid a soggy filling, make sure to squeeze out any excess moisture from the chopped zucchini pulp before adding it to the breadcrumb mixture.
• Cheese Please: For a richer flavor, sprinkle some grated Parmesan or Gruyere cheese on top of the breadcrumb topping before baking.
• Make-Ahead Magic: You can prepare the stuffed zucchini ahead of time and store them in the refrigerator for up to 24 hours before baking. Just add the breadcrumb topping right before baking to prevent it from getting soggy.

Serving & Storage Suggestions

These stuffed zucchini are delicious served warm as a main course or side dish. They pair perfectly with a simple salad or a side of rice. For a complete Uruguayan meal, serve them alongside some grilled asado.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat them in the oven at 350°F (175°C) until heated through, or microwave them in short intervals. They can also be frozen for longer storage. Wrap them individually in plastic wrap and then place them in a freezer bag. Thaw them overnight in the refrigerator before reheating.
