This easy homemade vegetarian lasagna combines a savory eggplant caponata, chopped kale, low FODMAP tomato sauce, and gluten-free no-boil lasagna noodles for a comforting, pantry-friendly meal. It’s hearty and satisfying, with options for vegan or dairy-free substitutions.
For a while I made eggplant caponata almost weekly and found ways to fold it into many dishes. Somehow I never thought to use it in a low FODMAP lasagna while developing vegetarian recipes for my cookbook, and I’ve been missing out ever since. After hearing from many of you on Instagram asking for vegetarian low FODMAP dinner ideas, this lasagna felt like the obvious next recipe to share.
I often use mushrooms or eggplant as a meat substitute in low FODMAP bolognese-style sauces. For this lasagna, eggplant caponata provides depth and a meaty texture without animal protein. The caponata’s sweet-and-sour notes—thanks to a splash of balsamic and a few golden raisins—add an unexpected but delightful contrast in each bite.
To keep the lasagna low FODMAP, I reduced the cheese and increased the vegetables. Frozen chopped kale is a convenient option because it’s already pre-chopped and melts seamlessly into the filling; fresh kale works fine too. For lactose-sensitive diets, small portions of certain cheeses are typically tolerated—this recipe uses modest amounts of mozzarella so the dish stays within low FODMAP guidelines when divided into multiple servings.
I used an almond-based ricotta when available, but it’s optional—this lasagna works well without it. If you prefer a fully dairy-free or vegan version, use lactose-free or plant-based cheeses, avoiding cashew-based products if you’re strictly following low FODMAP recommendations. A little fresh mozzarella torn on top looks beautiful, combined with a small amount of shredded part-skim mozzarella for melt and texture.
Most gluten-free pastas are low FODMAP provided they aren’t legume-based; rice, corn, oat, or quinoa noodles are safe choices. I like no-boil gluten-free lasagna sheets from the freezer section for convenience. If using regular dried or pre-cooked noodles, follow package instructions and adjust baking time or liquid as needed.
Another important adaptation is the tomato sauce: many store-bought sauces contain onions and garlic. Choose a certified low FODMAP tomato sauce or one labeled without garlic and onion. That makes assembling this lasagna straightforward and worry-free.
I hope this vegetarian low FODMAP lasagna brings a little comfort to your meal rotation. If you’re unsure about the raisins in the caponata, feel free to omit them—though they are a traditional element in Sicilian caponata and do add a nice sweet-tart note. Serve the lasagna with a simple green salad and a low FODMAP dressing for a complete meal.
With health and hedonism,

Low FODMAP Vegetarian Eggplant-Kale Lasagna
print recipe
The eggplant-kale caponata delivers a rich, savory base that stands in for meat sauces, while golden raisins and balsamic provide a classic sweet-and-sour counterpoint.
Ingredients
- 2 tablespoons olive oil
- 1 medium eggplant about 3/4 pound, diced
- 1/2 teaspoon sea salt
- ½ teaspoon red chili flakes
- 1 medium vine or Roma tomato diced
- 8 ounces frozen chopped kale or 1 bunch fresh finely chopped
- 2 cups low FODMAP tomato sauce 16 ounces
- 2 tablespoons golden raisins
- 1 tablespoon balsamic vinegar
- ¼ cup torn basil leaves divided
- 9 ounces gluten-free no-boil lasagna noodles about 6 sheets
- 8 ounces plant-based ricotta (optional)
- 5 ounces shredded mozzarella I used a combination of part-skim and fresh
Instructions
-
Preheat the oven to 350°F (175°C).
-
In a large skillet, heat the olive oil. Sauté the diced eggplant over medium-high heat until it begins to soften, about 8 minutes. Add the sea salt and red pepper flakes. Stir in the diced tomato, scraping up any browned bits, and cook until the tomato softens, about 3 minutes. Add the chopped kale and continue to sauté until very wilted and most of the liquid has evaporated, about 4 more minutes.
-
Remove from heat and stir in the golden raisins, balsamic vinegar, and half of the torn basil.
-
Spread 1/2 cup of the tomato sauce in the bottom of a 9 x 13-inch casserole dish. Arrange a first layer of noodles so they overlap slightly. Spread half the ricotta (if using) over the noodles, then half the eggplant mixture, followed by another 1/2 cup sauce and 1/4 cup shredded mozzarella. Repeat the layers once more.
-
Finish with a final layer of noodles, the remaining tomato sauce, the rest of the shredded mozzarella and the remaining basil leaves.
-
Bake for 30–40 minutes, or until the noodles are tender and the top is beginning to brown.
-
Allow the lasagna to rest for 5 minutes before slicing and serving.
