Baked Eggplant

Pin it

Introduction

This baked eggplant is a vegetable-forward dish built on sautéed mushrooms, tomatoes, walnuts, and capers, finished under the broiler and baked until tender. The filling is savory and textured, with cinnamon adding warmth without sweetness, and it works as a meatless main course or a substantial side. You’ll scoop out the eggplant flesh, cook it down with aromatics, then return the mixture to the shells and bake.

Recipe Details

• Prep Time: 20 minutes
• Cook Time: 50 minutes
• Total Time: 70 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

Spiced variation: Add ¼ tsp cumin and a pinch of cayenne pepper to the sautéed mixture for a warmer, slightly spiced profile that complements the cinnamon.

Nut swap: Substitute sunflower seeds or pine nuts for the walnuts if you prefer a milder flavor or have a nut allergy; use the same weight and coarsely grind them the same way.

Add fresh herbs: Stir 2 tablespoons of chopped fresh parsley or mint into the filling just before stuffing the shells for brightness and color.

Lighter filling: Reduce the walnuts to ⅓ cup and increase the mushrooms to ½ lb for a less dense, more vegetable-forward filling.

Cheese topping: Sprinkle 3-4 tablespoons of grated Parmesan or crumbled feta over the tomato slices before baking for a savory, salty finish.

Tips for Success

Don’t remove too much eggplant flesh: Leave a sturdy ¼-inch rind so the shells hold their shape during broiling and baking. A grapefruit knife works best because its curve follows the contour of the eggplant.

Watch the broiler closely: Eggplant shells can go from tender to charred quickly under direct heat. Check them at 8 minutes; if the skin is browning too fast but the flesh isn’t fork-tender, move the rack down slightly and broil longer.

Sauté until soft but chunky: Cooking the filling for only 5–10 minutes keeps the texture interesting. If you cook it longer, the vegetables will break down into a paste, which is fine if you prefer, but the recipe is designed for a coarser consistency.

Taste and adjust salt: Capers are very salty, so add them to the filling and taste before adding extra salt to the dish.

Make ahead: You can prepare and fill the eggplant shells up to 4 hours ahead, cover them, and refrigerate. Add 5–10 minutes to the baking time if baking from cold.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. The shells soften as they cool but remain intact. Reheat on a baking sheet at 350°F for 12–15 minutes, covered with foil to prevent drying, or microwave a single portion covered for 2–3 minutes. This dish does not freeze well; the eggplant becomes mushy and the texture breaks down when thawed.

FAQ

Can I use Italian eggplants or smaller Japanese eggplants instead of medium ones?

Yes, but adjust your quantity. Aim for about 2 lb total weight. Smaller eggplants will cook faster under the broiler (check at 5–6 minutes), so watch them closely.

What if I don’t have a grapefruit knife?

A sturdy teaspoon or a small serrated knife works, though it takes a bit more effort. The goal is to hollow the eggplant without puncturing the skin, so move slowly and carefully around the flesh.

Can I substitute the capers?

Capers provide a salty, briny bite. If you don’t have them, skip them and increase the salt to ½ tsp more, or use 2 tablespoons of chopped green olives for a similar effect.

Why does my filling look dry after sautéing?

The vegetables release moisture as they cook, but eggplant and mushrooms can absorb it quickly. If the mixture seems too dry before adding the walnuts and tomato paste, add 2–3 tablespoons of water or vegetable broth to loosen it slightly.
