Ingredients You’ll Need
Here’s a breakdown of the key ingredients for this vegan potato leek gratin:
* **Potatoes:** Yukon Gold potatoes are ideal for this recipe. Their creamy texture and slightly sweet flavor complement the leeks perfectly. Russet potatoes can also be used, but they may require a bit more cooking time.
* **Leeks:** Leeks are the star of the show, adding a delicate oniony flavor that is both sweet and savory. Make sure to clean them thoroughly, as they tend to trap dirt between their layers.
* **Raw Cashews:** These form the base of our creamy vegan sauce. Soaking them in hot water softens them, making them easier to blend into a smooth and luscious cream.
* **Vegetable Broth:** Adds depth of flavor to the cashew cream sauce. Use a good quality vegetable broth for the best results.
* **Nutritional Yeast:** This deactivated yeast adds a cheesy, umami flavor to the sauce. It’s a key ingredient in many vegan cheese recipes.
* **Plant-Based Milk:** Unsweetened and unflavored plant-based milk, such as almond milk, soy milk, or oat milk, adds richness to the sauce. Make sure it’s unsweetened to avoid altering the flavor profile of the gratin.
* **Lemon Juice:** A touch of lemon juice brightens the sauce and balances the richness.
* **Garlic:** Adds a pungent and aromatic flavor to the sauce.
* **Olive Oil:** Used for sautéing the leeks and coating the baking dish.
* **Nutmeg:** A pinch of nutmeg adds a warm and comforting aroma to the gratin.
* **Salt and Pepper:** To taste, of course!
* **Optional Toppings:** Breadcrumbs, fresh herbs (such as thyme or parsley), or vegan parmesan cheese can be added for extra flavor and texture.

Step-by-Step Instructions
Let’s get cooking! Here’s a detailed guide to making this delicious vegan potato leek gratin:
**1. Prepare the Potatoes and Leeks:**
* Wash and scrub the potatoes thoroughly. Using a mandoline slicer or a sharp knife, thinly slice the potatoes to about 1/8 inch thickness. Place the sliced potatoes in a large bowl and set aside.
* Cut off the dark green tops of the leeks, leaving only the white and light green parts. Slice the leeks thinly and wash them thoroughly to remove any dirt or grit. Leeks tend to trap dirt between their layers, so it’s important to rinse them well. You can do this by placing the sliced leeks in a bowl of cold water and swishing them around. The dirt will sink to the bottom. Lift the leeks out of the water and drain them in a colander.
**2. Make the Cashew Cream Sauce:**
* Drain the soaked cashews and place them in a high-speed blender. Add the vegetable broth, nutritional yeast, plant-based milk, lemon juice, garlic, salt, and pepper.
* Blend on high speed until the mixture is completely smooth and creamy. This may take a few minutes, depending on the strength of your blender. If the sauce is too thick, add a little more plant-based milk until it reaches your desired consistency.
* Taste the sauce and adjust the seasoning as needed. You may want to add more salt, pepper, or nutritional yeast to taste.
**3. Sauté the Leeks:**
* Heat the olive oil in a large skillet or sauté pan over medium heat.
* Add the sliced leeks to the skillet and sauté them for about 5-7 minutes, or until they are softened and slightly translucent. Be careful not to brown them too much. You want them to be tender and sweet.
* Season the leeks with a pinch of salt and pepper.
**4. Assemble the Gratin:**
* Preheat your oven to 375°F (190°C).
* Lightly grease a 9×13 inch baking dish with olive oil or cooking spray.
* Pour a thin layer of the cashew cream sauce into the bottom of the baking dish.
* Arrange a layer of potato slices over the sauce, overlapping them slightly. Make sure the potatoes cover the entire bottom of the dish.
* Sprinkle a layer of sautéed leeks over the potatoes.
* Pour another layer of cashew cream sauce over the leeks, ensuring that the potatoes and leeks are well coated.
* Repeat these layers until all of the potatoes and leeks are used, finishing with a layer of cashew cream sauce on top.
**5. Bake the Gratin:**
* Cover the baking dish with aluminum foil.
* Bake for 45 minutes.
* Remove the foil and bake for another 15-20 minutes, or until the top is golden brown and the potatoes are tender. You can test the potatoes for tenderness by inserting a fork into the center of the gratin. If the fork slides in easily, the potatoes are done.
* If you’re using breadcrumbs, sprinkle them over the top of the gratin during the last 10 minutes of baking. This will give them a chance to toast and become golden brown.
**6. Let it Rest:**
* Remove the gratin from the oven and let it rest for at least 10-15 minutes before serving. This will allow the sauce to thicken slightly and the flavors to meld together.
**7. Serve and Enjoy:**
* Garnish with fresh herbs (such as thyme or parsley) and vegan parmesan cheese, if desired.
* Serve the vegan potato leek gratin warm as a main course or side dish.
Tips and Variations
Here are some helpful tips and variations to customize this vegan potato leek gratin to your liking:
* **Use a Mandoline:** A mandoline slicer will help you slice the potatoes and leeks quickly and evenly. This is especially helpful if you’re making a large batch of gratin.
* **Soak the Cashews:** Soaking the cashews is essential for creating a smooth and creamy sauce. If you’re short on time, you can boil the cashews for 15 minutes instead of soaking them for 30 minutes.
* **Don’t Overcook the Leeks:** Be careful not to overcook the leeks, as they can become bitter. You want them to be tender and slightly translucent.
* **Adjust the Seasoning:** Taste the cashew cream sauce and adjust the seasoning to your liking. You may want to add more salt, pepper, nutritional yeast, or lemon juice.
* **Add Different Vegetables:** Feel free to add other vegetables to the gratin, such as carrots, celery, or mushrooms. Simply sauté them along with the leeks.
* **Spice it Up:** Add a pinch of red pepper flakes to the cashew cream sauce for a touch of heat.
* **Make it Cheesy:** Add more nutritional yeast to the cashew cream sauce for a more pronounced cheesy flavor. You can also add vegan cheese shreds to the gratin.
* **Add Herbs:** Experiment with different herbs, such as thyme, rosemary, or sage, to add a unique flavor to the gratin.
* **Make it Gluten-Free:** Ensure the plant-based milk you use is gluten-free to make the entire dish gluten-free.
