Aubergine (or Eggplant) Memories: I remember as a kid, aubergines were a bit of a mystery vegetable to me. They looked so exotic with their deep, glossy purple skins, almost too beautiful to eat! Growing up, they were never a household staple, but as I got older and more adventurous in the kitchen, I found myself reaching for them more often. Turns out, they’re incredibly versatile and, dare I say, underrated! This gratin recipe is my way of celebrating the humble aubergine in all its hearty, savory glory.

Why Aubergine?

Aubergines (or eggplants, depending on where you’re from) have been part of the culinary world for thousands of years, particularly celebrated in Mediterranean and Asian cuisines. They’re part of the nightshade family, which includes tomatoes and peppers, and have a unique ability to absorb flavors and blend seamlessly into dishes. This makes them perfect for a gratin, where they can meld with the creamy layers of potatoes and herbs to create something truly magical.

Health Benefits: Aubergines are a low-calorie veggie, full of fiber, vitamins, and minerals, but the real magic lies in their antioxidant properties. They contain a unique antioxidant called nasunin, which is found in their purple skin and is known for helping protect brain cells. They’re also high in anthocyanins and chlorogenic acid, compounds that are thought to help reduce inflammation and protect against heart disease. So basically, they’re a delicious way to sneak in some health benefits!

Ingredients
  

  • 2 large aubergines thinly sliced
  • 4 medium potatoes thinly sliced
  • 2 tbsp olive oil
  • 1 large onion finely chopped
  • 3 cloves garlic minced
  • 2 cups unsweetened plant-based milk such as almond or soy milk
  • 1 cup vegetable broth
  • 3 tbsp all-purpose flour
  • 1 tsp dried thyme
  • 1 tsp dried rosemary
  • 1/4 tsp nutmeg
  • Salt and black pepper to taste
  • 1 cup vegan mozzarella shredded (optional)
  • 1/4 cup nutritional yeast optional
  • Fresh parsley chopped (for garnish)

Instructions
 

  • Preheat the Oven: Preheat your oven to 375°F (190°C).
  • Prepare the Vegetables: Thinly slice the aubergines and potatoes using a mandoline or a sharp knife. Set aside.
  • Make the Creamy Sauce: Heat the olive oil in a medium saucepan over medium heat. Add the chopped onion and garlic, and sauté until soft and translucent, about 5 minutes.
  • Stir in the flour and cook for another 1-2 minutes, stirring constantly, to create a roux.
  • Gradually whisk in the plant-based milk and vegetable broth until smooth. Bring the mixture to a simmer and cook until it thickens, about 5 minutes.
  • Add the dried thyme, dried rosemary, nutmeg, salt, and black pepper. Stir to combine.
  • Assemble the Gratin: Lightly grease a large baking dish with olive oil.
  • Arrange a layer of potato slices at the bottom of the dish, followed by a layer of aubergine slices.
  • Pour a portion of the creamy sauce over the layered vegetables.
  • Repeat the layering process, alternating between potatoes and aubergines, and pouring sauce in between layers, until all the vegetables and sauce are used.
  • If using, sprinkle shredded vegan mozzarella and nutritional yeast between the layers and on top.
  • Bake the Gratin: Cover the baking dish with aluminum foil and bake in the preheated oven for 45 minutes.
  • Remove the foil and bake for an additional 20-25 minutes, or until the top is golden brown and the vegetables are tender.
  • Serve: Allow the gratin to cool for a few minutes before serving.
  • Garnish with chopped fresh parsley.

A Personal Twist

I love to sprinkle a few red pepper flakes on top for a subtle heat that plays beautifully with the earthy aubergine and creamy potatoes. And if I’m feeling fancy, a little drizzle of balsamic reduction right before serving adds an unexpected pop of sweetness. It’s those little tweaks that make a recipe truly feel like your own!
