How to Prepare Eggplant

Wash the eggplant and trim off the stem. The skin is edible, although you can peel it if you prefer a softer texture. Slice the eggplant according to how you plan to use it, keeping the pieces as even as possible so they cook at the same rate.

Eggplant Lasagna Sheets

Cut the eggplant lengthwise into slices about 1/4 inch thick. Lightly sprinkle the slices with salt and let them sit for about 20–30 minutes. Pat away the released moisture with paper towels or a clean kitchen towel before cooking.

Brush the slices lightly with olive oil and roast at 400°F for about 15–20 minutes, turning once, until tender and flexible. Use the cooked slices in place of lasagna noodles, layering them with sauce, cheese, meat, or other fillings.

Eggplant Noodles or Strips

Cut eggplant into long, thin strips for use in skillet dishes or as a substitute for wider pasta noodles. Sauté the strips in a small amount of olive oil over medium-high heat until tender and lightly browned. Avoid overcrowding the skillet, which can cause the eggplant to steam and become overly soft.

Using Eggplant as a Pasta Substitute

Eggplant works especially well in lasagna, casseroles, baked pasta-style dishes, and recipes with tomato, meat, or cheese-based sauces. Its mild flavor absorbs sauces and seasonings well.

Eggplant does not have the firm or chewy texture of traditional pasta. It becomes soft and tender as it cooks and can release considerable moisture, so removing excess water before assembling baked dishes helps prevent a watery result.

Quick Tip: Pre-cook eggplant slices before using them in lasagna or casseroles. Putting raw eggplant directly into a layered dish can release excess moisture as it bakes and leave the finished dish watery.
