Jump to Recipe Print Recipe
Sabich is one of Israel’s most beloved street foods – traditionally a pita sandwich stuffed with fried eggplant, hard-boiled eggs, Israeli salad, and tahini. This recipe transforms those classic flavors into an elegant, low-carb meal by using meaty portobello mushrooms as edible bowls. Perfect for weeknight dinners or impressive enough for guests, these stuffed mushrooms deliver all the satisfying textures and Middle Eastern flavors of the original while being completely kosher and vegetarian. Using a reliable toaster oven means you can make this dish without heating up your entire kitchen, and everything cooks on a single pan for easy cleanup. The combination of roasted eggplant, creamy eggs, and nutty tahini creates a protein-rich meal that’s both nutritious and deeply satisfying. What makes this recipe particularly practical is how forgiving it is – the vegetables roast together on one toaster oven baking sheet, and you can easily adjust the toppings based on what you have on hand. The portobello mushrooms become tender and slightly crispy at the edges, creating the perfect vessel for the vibrant Israeli-inspired toppings.

Ingredients Method Notes

Ingredients
  

Mushrooms and Eggplant
  • 4 large portobello mushroom caps stems removed
  • 1 medium eggplant cut into 1/2-inch cubes
  • 3 tablespoons olive oil divided
  • 1 teaspoon salt divided
  • 1/2 teaspoon black pepper
Filling and Toppings
  • 2 large hard-boiled eggs peeled and chopped
  • 1/2 cup cucumber diced small
  • 1/2 cup tomato diced small
  • 2 tablespoons fresh parsley chopped
  • 1/4 cup tahini
  • 2 tablespoons lemon juice
  • 2-3 tablespoons water to thin tahini
  • 1 clove garlic minced

Method
 

  1. Preheat your toaster oven to 400°F (200°C). Line a toaster oven baking sheet with parchment paper or lightly grease it.
  2. Toss the cubed eggplant with 2 tablespoons olive oil and 1/2 teaspoon salt. Spread on half of the prepared baking sheet. Brush the portobello mushroom caps with remaining 1 tablespoon olive oil on both sides and season with remaining 1/2 teaspoon salt and black pepper. Place gill-side up on the other half of the baking sheet.
  3. Roast in the toaster oven for 20-25 minutes, flipping the mushrooms halfway through. The eggplant should be golden and tender, and the mushrooms should be softened with slightly crispy edges.
  4. While the vegetables roast, prepare the tahini sauce by whisking together tahini, lemon juice, minced garlic, and water until smooth and pourable. Season with a pinch of salt to taste.
  5. Make the Israeli salad by combining diced cucumber, tomato, and parsley in a small bowl. Season lightly with salt.
  6. Once the mushrooms and eggplant are done, fill each mushroom cap with roasted eggplant, top with chopped hard-boiled egg and Israeli salad.
  7. Drizzle generously with tahini sauce and serve immediately while warm.

Notes

You can prepare the hard-boiled eggs and tahini sauce ahead of time. For extra flavor, add a sprinkle of amba (pickled mango sauce) or schug (Yemenite hot sauce) on top. The mushrooms can be served as a main dish or cut in half for appetizers. Store any leftover components separately in the refrigerator for up to 2 days.

What temperature do you cook stuffed portobello mushrooms in a toaster oven?

Cook stuffed portobello mushrooms in a toaster oven at 400°F for best results. Roast the mushrooms for approximately 15-20 minutes until they are tender and the edges are slightly crispy, ensuring the filling is heated through completely.

How do you prevent stuffed portobello mushrooms from getting watery?

Remove the mushroom gills with a spoon before stuffing to significantly reduce excess moisture during cooking. You can also pre-roast the portobello caps for 5-7 minutes at 400°F and pat them dry with paper towels before adding the filling.

Can you make sabich stuffed portobello mushrooms ahead of time?

You can prep the components up to 24 hours in advance by roasting the eggplant and hard-boiling the eggs, storing them separately in airtight containers in the refrigerator. Assemble and stuff the mushrooms just before toaster oven cooking to prevent soggy results, then bake fresh for 15-20 minutes at 400°F.

What is sabich and what are the traditional ingredients?

Sabich is a popular Israeli street food sandwich traditionally made with fried eggplant, hard-boiled eggs, Israeli salad, and tahini sauce, typically served in a pita. This dish originated in the Iraqi Jewish community and is now one of Israel’s most beloved vegetarian street foods.

How long do leftover stuffed portobello mushrooms last in the refrigerator?

Leftover stuffed portobello mushrooms keep well in an airtight container in the refrigerator for up to 3 days. Reheat them in your toaster oven at 350°F for 8-10 minutes to restore their texture, though fresh toppings like Israeli salad and tahini should be added after reheating.
