Eggplant Lasagna Boats with mushrooms, spinach, and a secret ingredient to boost protein. This stuffed eggplant lasagna recipe is vegetarian, low carb, and nutrient-packed.

Why You’ll Love this Eggplant Lasagna Recipe

Not only is this stuffed eggplant recipe way simpler than making actual lasagna, it’s also more nutritious.

It features a trifecta of veggies, protein-packed cottage cheese (YES, cottage cheese–more on that later), and lycopene-rich tomato rich.

If you’re following a low carb lifestyle, this recipe is especially well-suited for you. While you have the option to add meat, I find it plenty satiating as is.

Give this recipe a try for the ultimate low carb eggplant lasagna experience. And, if you have leftovers, it reheats exceptionally well the next day.

The Ingredients

• Eggplant: You need two medium globe eggplants for this recipe. Alternatively, you can use three smaller ones, however they need to be the globe variety. (Unfortunately, Japanese eggplants are too slender to sufficiently stuff.)
• Mushrooms: I love using sliced baby bella mushrooms for meaty texture and a blast of umami. Alternatively, you can use shiitake, white button, or chopped portobello mushroom caps.
• Spinach: Use baby spinach or lacinato kale for a mega nutrient boost. This greens will cook down a LOT, so feel free to add a few extra handfuls to bulk up the filling.
• Tomato Sauce: You can use either homemade or store-bought marinara sauce for this recipe. My personal go-to is Rao’s, which tastes the freshest of any jarred variety I’ve tried.
• Cottage Cheese: I know this seems like a wildcard ingredient, however cottage cheese is an excellent substitute for ricotta. It’s rich in protein, and overall offers a better nutrient profile. My go-to brand is Good Culture, which has gut-healthy probiotics, too!
• Garlic: For an aromatic boost.
• Mozzarella: I strongly suggest buying a block of organic mozzarella and shredding it yourself. The pre-shredded stuff normally has additives that can affect meltability.

Step-by-Step Instructions

Step 1: Roast Eggplant. Slice the eggplants in half lengthwise, and brush the flesh with olive oil. Place eggplants halves, flesh side-down, on a rimmed baking sheet or 9×13″ pan. Bake for 20 to 25 minutes, until flesh softens.

Let stand at room temperature until cool enough to handle.

Step 2: Sauté Vegetables. Heat oil in a large skillet over medium heat. Once hot, add mushrooms and onion, and cook until soft, about 5 to 7 minutes.

Next, add chili flakes, garlic, spinach, salt, and pepper; cook 2 more minutes, until spinach wilts.

Step 3: Scoop Out Eggplant Flesh, leaving about a 1/2-inch-thick border around skin to create a boat.

Step 4: Add Eggplant to Pan with mushrooms, and mix to combine. Next, add 1 1/4 cups marinara sauce to the filling, and stir to combine.

Step 5: Stuff Eggplant. Pour remaining 1/2 cup marinara sauce into the bottom of a 13×9 inch pan.

Place the eggplant halves in the pan, and spoon the filling evenly into each. Spoon dollops of cottage cheese into eggplant, and scatter mozzarella overtop.

Step 6: Bake Lasagna Boats until the cheese melts, about 10 to 15 minutes. Broil for the final 2 to 3 minutes.

Serving Suggestions:

This low carb eggplant lasagna is mighty delicious on its own, however also plays with other dishes.

• To keep dinner low carb/keto-friendly, serve my Sautéed Broccoli or Cucumber Sesame Salad on the side.
• For a protein boost, serve these eggplant boats alongside Pan-Seared White Fish or my 5-Ingredient Maple-Mustard Salmon. You also can’t go wrong with some Chickpea Meatballs, which are a meal prep staple over here.
• If you’re not going the low-carb route, this dish is excellent with some homemade garlic bread. I usually make it myself using sourdough bread, grass-fed butter, and some freshly grated Parmesan cheese.

How to Store and Reheat:

• I do not recommend freezing cooked eggplant. Unfortunately, it become watery when thawed and doesn’t hold up well in the freezer.
• You can, however prep this recipe ahead and store it in the refrigerator!
• To Prepare Ahead: Roast the eggplant and prepare the filling up to 1 day in advance. Store each component separately in the refrigerator. Assemble the Eggplant Lasagna Boats just before baking or up to four hours in advance and refrigerate.
• Cooked Eggplant Lasagna Boats can be stored in the refrigerator for up to four days.
• To Reheat: Warm gently in the microwave or covered in a 300ºF oven, until heated through.

Eggplant Health Benefits:

Eggplants are part of the nightshades family, which have gained somewhat of a bad rap the last few years. This group of veggies contain trace amounts of the toxin solanine, which is responsible for their bitter taste. However, in order to notice any negative GI effects, one would need to consume a very large amount.

For this reason, eggplant certainly should not be avoided simply because it is a nightshade. Plus, eggplants are packed with an array of good-for-you nutrients. In addition to being rich in fiber, they also offer manganese (essential for normal growth), folate, potassium, plus vitamins K and C.

When shopping for eggplant, choose ones with shiny skin and a green stem, which are signs of freshness.
