Peel and cube the potatoes, then place them in a large pot of salted water. Bring the water to a boil and cook until the potatoes are soft, which takes about 15 minutes. Drain the potatoes and mash them with butter, milk, garlic powder, salt, and pepper until smooth.
While the potatoes are cooking, prepare the breaded chicken tenders according to package instructions. You can bake them in the oven or fry them in a pan for that extra crispiness.
Cook the sweet corn on the stovetop or microwave until heated through. At the same time, prepare the brown gravy by whisking it over low heat until smooth and warm.
Start with a generous scoop of mashed potatoes as your base. Layer the crispy chicken tenders on top, followed by corn and shredded cheddar cheese. Drizzle the brown gravy generously over everything.
Your chicken mashed potato bowls are ready! Serve hot and enjoy the cozy, savory flavors.
