How to Make Loaded Hashbrown Casserole
STEP 1. Shred the potatoes. Use a box grater or food processor to shred the peeled potatoes.
STEP 2. Soak in salt water. Place the shredded potatoes in a large bowl, cover with cold water, and add 1 teaspoon of salt. Soak for 10 minutes to remove excess starch.
STEP 3. Drain and dry. Drain the potatoes thoroughly and squeeze them very dry using a clean kitchen towel. Transfer to a bowl and toss with the remaining salt and olive oil. Set aside.
STEP 4. Cook the vegetables. Heat olive oil in a large skillet over medium heat. Add the onion and cook until soft and translucent, about 3–4 minutes.
STEP 5. Add bell pepper. Stir in the red bell pepper and cook for another 3–4 minutes until just tender.
STEP 6. Add corn and garlic. Stir in corn and garlic and cook for 30 seconds until fragrant.
STEP 7. Add spinach. Mix in the spinach and cook briefly until just wilted, then remove from heat.
STEP 8. Make the sauce. In a saucepan over medium heat, melt vegan butter. Whisk in the flour and cook for about 1 minute. Gradually whisk in the plant milk, stirring until smooth and thickened, about 3–4 minutes.
STEP 9. Add remaining sauce ingredients. Lower the heat and whisk in the vegan cream cheese, nutritional yeast, Dijon mustard, salt, black pepper, and smoked paprika until fully smooth.
STEP 10. Preheat the oven. Preheat to 375°F (190°C) and lightly grease a 9×13 baking dish.
STEP 11. Combine ingredients. In a large bowl, mix shredded potatoes, cooked vegetables, and the creamy sauce until evenly coated.
STEP 12. Spread in baking dish. Evenly spread the mixture into the prepared baking dish.
STEP 13. Prepare the topping. In a small bowl, mix the vegan shredded cheese, panko breadcrumbs, and olive oil. Sprinkle this mixture evenly over the casserole.
STEP 14. Bake. Bake uncovered for 45–50 minutes until bubbling and deeply golden on top.
STEP 15. Broil for crispiness. For extra crispiness, briefly broil for 2–3 minutes, watching closely to prevent burning.
STEP 16. Let rest. Allow to cool for 10 minutes before slicing so it sets nicely.

Pro Tips
To achieve the best results with your loaded hashbrown casserole, consider the following tips. Use freshly grated potatoes for optimal texture and avoid overly watery potatoes. Make sure to squeeze out as much moisture as possible to achieve that coveted crispy layer. If you prefer a stronger flavor, feel free to use more garlic or add herbs like thyme or rosemary to the vegetable mixture. When preparing the creamy sauce, whisk continuously to avoid clumps and ensure a silky-smooth consistency. If you want an extra kick, a dash of cayenne or crushed red peppers can elevate the flavor. For a cheesier experience, you can mix different types of vegan cheese. Lastly, let the casserole sit before slicing for perfect serving portions that hold together nicely.
Common Mistakes to Avoid
To make your cooking experience smoother, keep an eye out for these common mistakes when preparing your loaded hashbrown casserole. Avoid skipping the soaking step for the potatoes as it helps remove excess starch, ensuring a crispier texture. Don’t forget to adequately dry the potatoes, which prevents a soggy bottom. When sautéing the vegetables, be cautious not to overcook them; they should remain slightly firm for the best texture. Additionally, carefully monitor your casserole as it bakes to prevent burning. If you notice the top browning too quickly, cover it with foil until the rest of the casserole is cooked. Finally, allowing the casserole to rest after baking is crucial as it helps it set, making it easier to slice. Avoid rushing this step for the best presentation and texture.
Variations
• Add cooked quinoa or lentils for added protein.
• Swap out the vegetables for your favorites, like mushrooms or zucchini.
• Use sweet potatoes in place of Russet for a sweet twist.
• Incorporate your favorite spices, such as cumin or chili powder, for added flavor.
• Serve with a side salad to round out the meal.
Serving Ideas
This dish shines when served alongside a fresh green salad for a well-rounded meal. Pair it with a side of avocado slices for added creaminess and nutrients. It also complements perfectly with homemade coleslaw for an extra crunch. Consider offering a dollop of dairy-free sour cream or guacamole on the side that will enhance the creamy goodness and offer a flavor boost. For a heartier experience, serve it with homemade bread rolls or a slice of crusty baguette. The casserole can stand alone or elevate various sides to create an inviting spread.
Meal Prep & Storage
This loaded hashbrown casserole is ideal for meal prep. You can assemble it one day ahead, cover it, and store it in the refrigerator until you’re ready to bake.
