Adapt it for your goals.
Vegan
Replace butter with plant-based butter and use unsweetened oat or soy milk in the mash. The lentil filling is already vegan-friendly, making this a simple swap for a fully plant-based meal.
gluten freeGluten-free
Substitute the all-purpose flour with a gluten-free all-purpose blend or cornstarch slurry (1 tbsp cornstarch mixed with 2 tbsp cold water). The texture will remain thick and glossy.
low oilLow-oil
Sauté the vegetables in a splash of vegetable broth instead of olive oil. Reduce the butter in the mashed potatoes to 1 tbsp or replace with unsweetened applesauce for fewer calories.
cheesy toppingCheesy-topping
Stir ½ cup grated sharp cheddar into the mashed potatoes before spreading or sprinkle it on top during the last 5 minutes of baking for a golden, cheesy crust.
