The Most Delicious Dinner in 10 Minutes: Cheesy Ground Beef & Mashed Potato Casserole

Step 2: Prepare the Mashed Potato Layer

1. In a microwave-safe bowl or small saucepan, warm the mashed potatoes with milk, stirring until creamy and smooth.
2. Taste and adjust seasoning with a pinch of salt and pepper.

Step 3: Assemble the Casserole

1. In a small oven-safe dish or microwave-safe bowl, spread half of the mashed potatoes evenly across the bottom.
2. Layer the cooked ground beef on top of the potatoes.
3. Spread the remaining mashed potatoes over the beef layer.
4. Sprinkle shredded cheddar cheese generously on top.

Step 4: Melt the Cheese

• Microwave method (fastest): Microwave the casserole for 2–3 minutes until the cheese melts and becomes bubbly.
• Oven method: Preheat the oven to 375°F (190°C) and bake for 5–7 minutes, until the cheese is golden and bubbling.

Step 5: Serve and Enjoy

• Garnish with fresh parsley for a pop of color and freshness.
• Serve immediately while hot, perhaps with a side salad or steamed vegetables for a complete meal.

Tips for Maximum Flavor

• Add a splash of Worcestershire sauce or soy sauce to the beef for a deeper umami flavor.
• Mix in a handful of cooked peas or corn for extra veggies and sweetness.
• For a creamier casserole, stir in 2–3 tablespoons of sour cream into the mashed potatoes before layering.
