It’s a comforting side that will win over everyone at your table, vegans and non-vegans alike!

We’re thrilled to share one of the most remarkable potato dishes you’ll ever encounter. While we developed this recipe with “Vegan Scalloped Potatoes” in mind to cater to plant-based diets, its rich flavors and irresistible textures make it universally appealing. It’s the kind of dish that makes you forget it’s vegan and gluten-free, focusing solely on the pure joy of eating.

Fun fact: Our initial idea was to infuse the creamy sauce with pesto, but that experiment took an unexpected turn, resulting in an entirely black dish!

Ingredients for the Ultimate Vegan Scalloped Potatoes

Crafting this incredible dish requires a thoughtful selection of plant-based ingredients that come together to create a symphony of flavors and textures. Here’s what you’ll need:

For the Creamy Potato Base:

• Vegan Butter: Approximately 3 tablespoons. Choose a high-quality vegan butter (like Earth Balance) for the best flavor and richness in your sauce.
• Gluten-Free Flour: About 3 tablespoons. This acts as the thickener for our creamy sauce. If you don’t require the recipe to be gluten-free, regular all-purpose flour works perfectly.
• Shallot: 1 small, finely chopped. Shallots offer a delicate, sweet onion flavor that forms a crucial aromatic base for the sauce, providing more nuance than a regular onion.
• Vegetable Broth: 1 1/2 cups. Opt for a low-sodium, high-quality vegetable broth to control the seasoning and ensure a rich savory depth.
• Unsweetened Almond Milk: 1 1/2 cups. Plain, unsweetened almond milk is our go-to for its neutral flavor and creamy texture, making it an excellent dairy-free alternative. Feel free to use other unsweetened non-dairy milks like cashew or oat milk if preferred.
• Salt: 1 teaspoon. Essential for seasoning both the sauce and the potatoes. Adjust to your taste preferences.
• Black Pepper: 1/4 teaspoon. Freshly ground black pepper adds a subtle warmth and aroma.
• Potatoes: 3-4 medium-sized. The choice of potato is key! Yukon Golds are fantastic for their buttery texture and ability to hold their shape, while Russets offer a classic fluffy scalloped potato experience. Aim for firm, unblemished potatoes.

For the Crispy Pesto Topping:

• Vegan Butter: 2 tablespoons. Again, a good quality vegan butter is important for developing a rich, golden-brown crust.
• Gluten-Free Breadcrumbs: 1/2 cup. These create the delightful crunch. If gluten isn’t an issue, regular breadcrumbs are fine. Panko breadcrumbs also work wonderfully for extra crispiness.
• Minced Garlic: 1 clove. Freshly minced garlic provides a pungent, aromatic kick that is central to pesto’s flavor profile.
• Chopped Walnuts: 1/4 cup. Walnuts add a fantastic nutty flavor and additional texture to the topping, contributing to the “pesto” feel.
• Chopped Basil: 2 tablespoons. Fresh basil is non-negotiable for that bright, herbaceous pesto essence. Chop it just before adding to preserve its vibrant flavor.
• Pinch of Salt: To enhance the flavors of the topping.

Step-by-Step Guide: How to Make These Vegan Scalloped Potatoes

Creating this magnificent dish is a rewarding process. Follow these detailed instructions for perfectly creamy potatoes with a dazzling crispy topping:

1. Prepare Your Oven and Sauce Base: Begin by preheating your oven to 400 degrees Fahrenheit (200 degrees Celsius). While the oven heats, place a large pot or saucepan over medium heat. Add the vegan butter and the finely chopped shallots to the pot. Sauté the shallots for about 2 minutes, until they are softened and fragrant.
2. Build the Creamy Sauce: Sprinkle the gluten-free flour over the softened shallots and stir continuously for about 1 minute until a thick paste (roux) forms. This helps cook out the raw flour taste. Gradually whisk in the vegetable broth and unsweetened almond milk, ensuring there are no lumps. Season the sauce with 1 teaspoon of salt and 1/4 teaspoon of black pepper. Continue to cook, stirring occasionally, for 10-15 minutes, or until the sauce has thickened to a consistency similar to gravy. It should coat the back of a spoon. Remove from heat.
3. Slice and Layer the Potatoes: While the sauce is thickening, prepare your potatoes. Using a mandolin slicer or a very sharp knife, carefully slice the potatoes into thin, even rounds, approximately 1/8 inch thick. Uniform slices are crucial for even cooking. Spread about half of the prepared creamy sauce evenly over the bottom of a 10-inch oven-safe baking dish. Arrange a single layer of sliced potatoes over the sauce, slightly overlapping them. Repeat this layering process, alternating between sauce and potatoes, until all the potatoes and sauce are used, ensuring the final layer is sauce.
4. Initial Baking (Covered): Cover the baking dish tightly with aluminum foil. This traps steam, allowing the potatoes to cook through and become tender without drying out. Place the covered dish into the preheated oven and bake for 30-40 minutes, or until the potatoes are fork-tender. You can test for doneness by gently piercing a potato slice with a fork through the foil.
5. Prepare the Crispy Pesto Topping: While the potatoes are baking, it’s time to make our signature crispy topping. In a small saucepan, melt the 2 tablespoons of vegan butter over medium-low heat. Add the gluten-free breadcrumbs, minced garlic, chopped walnuts, and a pinch of salt. Cook, stirring frequently, for 2-3 minutes, until the breadcrumbs are golden brown and fragrant. Be careful not to burn the garlic. Remove the saucepan from the heat.
6. Add Basil and Final Bake (Uncovered): Once the potatoes are tender, carefully remove the baking dish from the oven and discard the foil. Stir the fresh chopped basil into the crispy breadcrumb mixture. Evenly spread this aromatic pesto topping over the tender scalloped potatoes. Return the dish to the oven, uncovered, for an additional 5 minutes. This final bake allows the topping to become perfectly golden and extra crispy.
7. Serve and Enjoy: Remove the finished scalloped potatoes from the oven. For the best flavor and texture, allow them to cool slightly for a few minutes before serving warm.

Expert Tips for Perfectly Vegan & Gluten-Free Scalloped Potatoes

Achieving the perfect balance of creamy and crispy is easier with a few insider tips:

• Potato Selection is Key: For the best results, choose waxy or all-purpose potatoes like Yukon Gold, Red Bliss, or even Russets. Waxy potatoes hold their shape well and provide a creamy texture, while Russets can offer a fluffier, more traditional scalloped potato feel.
• Slice Evenly for Consistent Cooking: This cannot be stressed enough! Whether using a mandolin or a sharp chef’s knife, aim for uniformly thin slices (about 1/8 inch). Inconsistent thickness will lead to some potatoes being undercooked and others overly soft.
• Don’t Rush the Sauce: Allow the creamy sauce to thicken properly, stirring occasionally. A well-thickened sauce will cling beautifully to the potato slices and prevent the dish from being watery. If it’s too thin, simmer it for a few more minutes.
• Flavor Boosters: For an extra layer of savory depth in your sauce, consider adding a tablespoon of nutritional yeast. This can impart a subtle “cheesy” flavor without any dairy. A tiny dash of Dijon mustard can also brighten the sauce.
• The Pesto Topping’s Secret: The balance of garlic, basil, and walnuts in the crispy topping is what makes it so distinctive. Don’t skimp on fresh basil; its vibrant flavor is essential. If you don’t have walnuts, pecans or even sunflower seeds could be a good substitute for crunch.
• Make Ahead Option: You can assemble the scalloped potatoes (without the crispy topping) up to one day in advance. Store covered in the refrigerator. When ready to bake, add an extra 10-15 minutes to the covered baking time, then proceed with the topping and final uncovered bake. Prepare the topping fresh just before the final bake for maximum crispiness.

Serving Suggestions and Storage

Serving:

These Vegan Scalloped Potatoes with Crispy Pesto Breadcrumbs are a versatile and impressive side dish. They pair wonderfully with a variety of main courses, from roasted vegetables and lentil loafs to grilled plant-based proteins.

Storage:

Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. To reheat, gently warm in the oven at 300°F (150°C) until heated through, or in a microwave. If reheating in the oven, you can cover it with foil to prevent drying out, or uncover for the last few minutes to try and crisp up the topping again.
