How to Make Loaded Hashbrown Casserole

Phase 1 – Prep

STEP 1. Shred the potatoes. Use a box grater or food processor to shred the peeled potatoes.

STEP 2. Soak the potatoes. 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 the potatoes. Drain the potatoes 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.

Phase 2 – Cook

STEP 4. Sauté the vegetables. Heat olive oil in a large skillet over medium heat. Add the diced onion and cook for 3–4 minutes until soft.

STEP 5. Add the bell pepper. Stir in the diced red bell pepper and cook for another 3–4 minutes until tender.

STEP 6. Incorporate garlic and corn. Add the corn and minced garlic, cooking for about 30 seconds until fragrant.

STEP 7. Add the spinach. Stir in the chopped baby spinach and cook briefly until just wilted. Remove from heat.

STEP 8. Make the creamy sauce. In a saucepan, melt the vegan butter over medium heat. Whisk in the flour and cook for about 1 minute.

STEP 9. Add plant milk and cream cheese. Gradually whisk in the plant milk, stirring constantly until thickened. Then lower heat and whisk in vegan cream cheese, nutritional yeast, Dijon mustard, salt, black pepper, and smoked paprika until smooth.

Phase 3 – Serve

STEP 10. Preheat the oven. Set your oven to 375°F (190°C). Lightly grease a 9×13 baking dish.

STEP 11. Combine the ingredients. In a large bowl, mix the shredded potatoes, cooked vegetables, and creamy sauce until evenly coated. Spread the mixture into the prepared dish.

STEP 12. Add the topping. In a small bowl, mix vegan shredded cheese, panko breadcrumbs, and olive oil. Sprinkle over the casserole.

STEP 13. Bake the casserole. Bake uncovered for 45–50 minutes until bubbling and golden on top. For extra crispiness, broil for 2–3 minutes at the end.

STEP 14. Rest before serving. Let the casserole rest for 10 minutes before slicing to allow it to set.

Why This Recipe Works

The charm of this Loaded Hashbrown Casserole lies in its textural contrasts. The crispy top, thanks to the panko and cheese, complements the creamy interior beautifully.

The even heat distribution in the oven ensures each bite is equally delicious, making every slice a crowd-pleaser.
