FAQs About Heart Healthy Eggplant Lasagna

Salting eggplant serves two purposes: it draws out excess water, which prevents the lasagna from becoming soggy, and it helps reduce some of the eggplant's natural bitterness.

Besides salting, you can reduce bitterness by choosing smaller, younger eggplants with smooth, shiny skin, as they tend to be less bitter than larger, older ones.

Absolutely. To incorporate ground turkey, simply brown one pound of lean ground turkey with your favorite Italian seasonings and layer it with the tomato sauce. This will add extra protein but will make the dish non-vegetarian.

Let the lasagna cool completely, then cover it tightly with plastic wrap and aluminum foil. It can be frozen for up to 3 months. To reheat, thaw it in the refrigerator overnight and bake at 350°F (175°C) until hot and bubbly, about 30-40 minutes.

How to Keep Eggplant From Getting Soggy

  • Draw out Moisture: The most important step is to remove excess water from the eggplant. Baking the slices before assembly is a great way to do this.
  • Salting (Optional but Recommended): For extra insurance, you can salt your eggplant slices and let them "sweat" in a colander for 30-60 minutes. Be sure to pat them completely dry with a paper towel before baking.
  • Slice Thinly: Slicing the eggplant into 1/8-inch slices helps it cook evenly and release moisture more effectively.

Serving & Storage Tips

  • Serving: Let the lasagna rest for at least 15 minutes after baking. This helps it set for cleaner slices. Serve with a simple green salad.
  • Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days.
  • Freezing: Freeze the cooled lasagna, tightly covered, for up to 3 months. Thaw in the refrigerator overnight before reheating.
  • Reheating: Bake uncovered at 350°F (175°C) for 20-30 minutes or until heated through.

Ingredient Substitutions

  • For Creamier Texture: Substitute part-skim ricotta with low-fat cottage cheese. Blend it briefly for a smoother consistency if desired.
  • To Add More Protein: Brown 1 pound of lean ground turkey or chicken and add it to the layers with the tomato sauce.
  • For a Different Format: Create eggplant roll-ups by spreading the cheese mixture on each baked eggplant slice, rolling it up, and placing it seam-side down in the baking dish before topping with sauce.
