Eggplant Lasagna Boats (Vegetarian, Low Carb)

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. (Or, alternatively, you can add quinoa for an additional vegetarian protein source.)

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

Recipe Ingredients:

• Eggplant: You need two medium to large size 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!
• 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 the Eggplant

Preheat oven to 425ºF. 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 9x13" pan. Bake for 20 to 25 minutes, until flesh softens. Let stand at room temperature until cool enough to handle.

Step 2: Sauté the Vegetables

Heat 2 Tbsp. of oil in a large skillet over medium heat. Once hot, add mushrooms and onion, and cook until softened, about 5 to 6 minutes. Next, add chili flakes, garlic, spinach, salt, and pepper; cook 2 more minutes, until spinach wilts.

Step 3: Scoop out Eggplant Flesh

Once the eggplant is cool enough to handle, use a spoon to hollow out eggplants, leaving about a ½-inch-thick border around skin to create a boat.

Transfer eggplant flesh to the pan with mushrooms, and mix to combine. (If needed, use a wooden spoon to break up pieces of eggplant.) Next, add 1 ¼ cups marinara sauce to the filling, and stir to combine.

Step 4: Stuff the Eggplant

Pour remaining ½ cup marinara sauce into the bottom of a 13x9 inch pan. Next, place the eggplant halves in the pan, and spoon the filling evenly into each. Spoon dollops of cottage cheese into stuffed eggplant, and scatter mozzarella overtop.

Step 5: Bake Eggplant Lasagna Boats

Place the pan back in the oven and bake for another 10 minutes, until the cheese melts. If desired, turn the broiler to high during the final 1 to 2 minutes. Finally, scatter fresh basil overtop and serve!

What are the Benefits of Eating Eggplant?

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.
