How to Make Vegan Tater Tot Casserole

Preheat the Oven: Start by preheating your oven to 375°F (190°C). Lightly grease a 9 × 13 inch baking dish for perfect non-stick results.
Sauté Veggies: In a large skillet, heat 1 tablespoon olive oil over medium heat. Add the finely diced yellow onion and celery, sautéing for 5–7 minutes until soft and lightly golden. Toss in 3 cloves of minced garlic and cook for about 30 seconds, just until fragrant.
Season the Mixture: Stir in 1/2 teaspoon ground cumin, 1/2 teaspoon smoked paprika, 1/2 teaspoon dried thyme, 1/4 teaspoon black pepper, and 3/4 teaspoon salt. Incorporate 1 cup of cooked brown or green lentils and 1/2 cup corn kernels, cooking for another 2–3 minutes to ensure it’s all well-seasoned and heated through.
Spread the Base: Transfer the lentil mixture into the prepared baking dish, spreading it out evenly and pressing it down slightly to create a compact layer.
Cook the Mushrooms: In the same skillet, add 2 tablespoons vegan butter and melt it over medium heat. Toss in 8 ounces finely chopped cremini mushrooms, cooking for 6–8 minutes until they release moisture and start to brown.
Thicken the Sauce: Sprinkle 2 tablespoons flour over the mushrooms, stirring well. Cook this for 1 minute to remove raw flour flavor.
Create Creaminess: Gradually pour in 1 1/4 cups unsweetened plant milk while stirring constantly. Bring it to a gentle simmer and cook for 4–6 minutes until the mixture thickens and becomes creamy.
Season the Sauce: Add in 1/2 teaspoon salt, 1/4 teaspoon black pepper, 1/2 teaspoon garlic powder, 1/2 teaspoon Dijon mustard, 1-2 teaspoons apple cider vinegar, and 1 tablespoon nutritional yeast. Taste and adjust seasoning as needed, then remove from heat.
Combine Everything: Pour the warm mushroom sauce evenly over the lentil layer, spreading it gently to cover it completely.
Cheese It Up: Sprinkle 1 1/2 cups shredded vegan cheddar cheese evenly across the top.
Tater Top: Arrange 5-6 cups of homemade vegan tater tots in a single layer on top of the cheese. To ensure they crisp up nicely, lightly spray with oil or drizzle 1–2 teaspoons of neutral oil over the top.
Bake Away: Bake uncovered for 40–45 minutes, observing as the casserole becomes bubbling around the edges and the tater tots turn a lovely golden brown.
Make It Crispier: If you desire extra crispiness, broil for 2–3 minutes at the end, keeping a close eye to avoid burning.
Rest and Serve: Let the casserole rest for 10 minutes before serving; this step allows flavors to meld beautifully.

Storing & Reheating

To store leftover Vegan Tater Tot Casserole, keep it in an airtight container at room temperature for up to 2 hours after cooking. If you have remaining portions, refrigerate in a sealed container for up to 5 days. For longer storage, it freezes well for up to 3 months. When you’re ready to enjoy it again, simply reheat in the oven at 350°F (175°C) for about 20-25 minutes until warmed through. Be mindful that the texture may slightly change, but giving it a quick crisp under the broiler for a couple of minutes can revive its original allure.

Ensure your lentils are perfectly cooked and not mushy before adding them to the casserole, as you want them to provide texture.
For an even creamier sauce, consider using a combination of plant milk and vegan sour cream.

Experiment with different vegetables like bell peppers or zucchini to change up the flavor profile.
