Baked Eggplant with Tomatoes Mushrooms Walnuts and Capers

Introduction

You scoop out the eggplant, sauté the chopped flesh with mushrooms, tomatoes, onions, garlic, walnuts, capers, and tomato paste, then bake it back in the shells until the top is bubbling. The broiling step makes the shells tender before filling, which keeps the final texture soft without turning the stuffing to mush. This works as a vegetarian main for four or a substantial side dish.

Recipe Details

• Prep Time: 25 minutes
• Cook Time: 50 minutes
• Total Time: 1 hour 15 minutes
• Servings: 4

Ingredients

• 2 ea. (2 lb / 900 g) medium eggplants
• ¼ lb (113 g) button mushrooms, sliced
• ½ lb (225 g) tomatoes, chopped
• 1 cup (240 ml) chopped onions
• 4 large cloves garlic, minced
• 1 tsp salt or to taste
• ½ tsp cinnamon
• Freshly-ground black pepper to taste
• 2 tsp extra virgin olive oil
• ⅔ cup (80 g) walnuts
• 3 heaping tbsp capers, drained
• 1 can (6 oz / 170 g) tomato paste
• 2-3 small tomatoes, sliced

Instructions

1. Cut eggplants in half lengthwise, leaving a ¼-inch (0.5 cm) rind.
2. Scoop out flesh using a curved serrated grapefruit knife, and coarsely chop it.
3. Place chopped eggplant into a large, deep skillet or flat-bottomed wok.
4. Rub inside of eggplant shells with olive oil and set aside on a baking sheet.
5. Add mushrooms, tomatoes, onions, garlic, salt, cinnamon, pepper, and olive oil to skillet, and sauté 5 to 10 minutes until soft but still chunky.
6. Place eggplant shells under the broiler, and broil 3 inches (7.5 cm) from heat source for 8-12 minutes, until fork tender (be careful not to burn).
7. Remove from heat source and set aside.
8. Coarsely grind walnuts, add to skillet along with capers and tomato paste, and mix well.
9. Fill eggplant shells with sautéed mixture and top with tomato slices.
10. Sprinkle with salt and pepper.
11. Bake uncovered at 375°F for 25-35 minutes.

Variations

• Swap the button mushrooms for cremini mushrooms if you want a deeper, more savory flavor in the filling.
• Replace the walnuts with pecans for a slightly sweeter, softer crunch that blends more smoothly into the tomato mixture.
• Use chopped green olives instead of capers if you want the same salty bite with less sharp acidity.
• Add 1 cup of cooked lentils to the filling after step 8 if you want a more filling main dish with a denser texture.
• Replace the cinnamon with ½ teaspoon ground cumin for a more earthy, less sweet spice profile.

Tips for Success

• Leave the full ¼-inch rind when you scoop the eggplants so the shells hold their shape after broiling and baking.
• Stop the sauté in step 5 when the vegetables are soft but still chunky; if you cook it down too far, the filling can turn pasty.
• Watch the eggplant shells closely under the broiler, especially around the edges, since they can go from tender to scorched quickly.
• Grind the walnuts coarsely, not into a powder, so they add texture instead of disappearing into the tomato paste.
• Bake until the tomato slices on top look slightly collapsed and the filling is hot all the way through.

Storage and Reheating

Store leftovers in an airtight container in the fridge for up to 4 days. You can also freeze portions in a freezer-safe container for up to 2 months, but the eggplant will be softer after thawing.

Reheat in a 350°F oven, covered loosely with foil, for 15 to 20 minutes until heated through. For a single portion, the microwave works well in 2 to 3 minutes on medium power; stop once or twice so the center heats evenly.

FAQ

Can you make this ahead of time?

Yes. You can prepare the filling and broil the eggplant shells a day ahead, then assemble and bake when you need it.

Do you need to salt the eggplant before cooking?

No. The broiling and baking steps soften the eggplant well without pre-salting, and the filling has enough tomato paste and capers to keep the flavor concentrated.

What can you use instead of walnuts?

Pecans or almonds work well. Pecans give a softer, sweeter result, while almonds stay firmer and a bit drier.

How do you know the eggplant shells are ready for filling after broiling?

A fork should slide into the flesh with little resistance, but the shells should still hold their shape. If they look deeply browned at the edges, pull them before they dry out.
