Equipment

<ul class="equipment-main-list"><li class="equipment-single-item">25cm x 35cm (9x13-inch) baking dish</li><li class="equipment-single-item">Large skillet or sauté pan</li><li class="equipment-single-item">Wooden spoon or spatula</li></ul>

Directions

<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 200°C (400°F) and set aside your baking dish. Keep the tater tots frozen until ready to use - this ensures they'll maintain their shape and crisp up beautifully in the oven.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Heat olive oil in a large skillet over medium heat. Add the diced onion and cook for 4-5 minutes until translucent. Add the garlic and cook for another 30 seconds until fragrant, being careful not to let it brown or burn.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Add the mushrooms, carrots, and bell pepper to the skillet. Cook for 6-8 minutes, stirring occasionally, until the vegetables have softened and the mushrooms have released their moisture. The natural umami from properly sautéed mushrooms will add depth to your casserole's flavor profile.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Add the plant-based mince to the skillet and break it up with your wooden spoon. Cook for 3-4 minutes until it starts to brown. If using tofu instead, ensure you've pressed it well to remove excess moisture before crumbling – this allows it to absorb more flavor.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Stir in the tomato paste, soy sauce, smoked paprika, oregano, and thyme. Cook for 1-2 minutes to bloom the spices and develop their flavors. This step is crucial for building complexity in your casserole base.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Sprinkle the flour over the mixture and stir continuously for about 2 minutes. The flour will coat the vegetables and create a roux when we add liquid, which thickens our sauce beautifully without requiring dairy.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Gradually pour in the vegetable stock while stirring constantly to prevent lumps from forming. Once incorporated, add the plant-based milk and nutritional yeast, continuing to stir. Bring the mixture to a gentle simmer and cook for 3-4 minutes until it starts to thicken. The nutritional yeast adds a subtle cheesy flavor that enhances the creamy texture.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Stir in the frozen peas and corn – no need to thaw them first as they'll cook perfectly in the oven. Season the mixture with salt and pepper to taste. Remember that tater tots are already salted, so be mindful not to over-season your filling.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Transfer the filling mixture to your baking dish, spreading it evenly. Allow it to cool slightly for 5 minutes – this helps prevent the tater tots from sinking into the filling when you arrange them.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Arrange the frozen tater tots in neat rows on top of the filling, covering the entire surface. For the crispiest result, place them close together but not overlapping. This creates a beautiful golden crown for your casserole with maximum crunch.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>Bake in the preheated oven for 30-35 minutes, until the tater tots are golden brown and crispy, and the filling is bubbling around the edges. If the tots aren't browning enough, you can switch to the grill/broiler setting for the final 2-3 minutes, but watch carefully to prevent burning.</li><li class="MethodStepper"><h4 class="step-title">Step 12</h4>Remove from the oven and let the casserole rest for 5-10 minutes before serving. This resting period allows the filling to set slightly, making it easier to portion. Garnish with fresh chopped parsley if desired, and serve hot. The contrast between the crispy topping and creamy filling is what makes this dish so satisfying!</li></ol>

Can I make this tater tot bake ahead of time?

Yes! Prepare the filling up to 2 days ahead and store in the refrigerator. When ready to serve, bring the filling to room temperature, top with frozen tater tots, and bake as directed. For longer storage, freeze the unbaked casserole for up to 3 months and bake from frozen.

What can I use instead of plant-based mince in a vegan casserole?

Great alternatives include crumbled firm tofu, cooked lentils, finely chopped walnuts mixed with mushrooms, or commercial meat alternatives like Quorn or Beyond Meat crumbles. For a less processed option, try a mixture of chopped mushrooms, cooked quinoa and beans for texture and protein.

How do I ensure my tater tots stay crispy on top of a casserole?

For perfectly crispy tater tots, keep them frozen until ready to use, allow the filling to cool slightly before topping, arrange tots in a single layer without overlapping, and bake in a hot oven (200°C/400°F). For extra crispiness, use the grill/broiler setting for the final 2-3 minutes of cooking.
