Ingredients
  

For the Cheesy Mashed Potatoes
  • 1.5 lbs russet potatoes, peeled and cut into evenly-sliced chunks Medium-large for even cooking.
  • 4 tablespoons butter For flavor and creaminess.
  • 1/4 cup half & half To achieve a smooth texture.
  • 3/4 teaspoon kosher salt For seasoning the potatoes.
  • 1/4 teaspoon ground black pepper For seasoning the potatoes.
  • 1/2 cup shredded medium cheddar cheese Stirred into the mash.
For the Meat & Veggie Filling
  • 2 tablespoons vegetable oil For cooking the meat and vegetables.
  • 1 cup chopped yellow onion For flavor base.
  • 2 cloves garlic, pressed or minced For additional flavor.
  • 1.5 lbs ground round (ground beef) For a rich meaty flavor.
  • 1 teaspoon kosher salt For seasoning the meat.
  • 1/2 teaspoon ground black pepper For seasoning the meat.
  • 2 tablespoons all-purpose flour To help thicken the sauce.
  • 2 teaspoons tomato paste For depth of flavor.
  • 1/2 cup Guinness stout beer For the signature stout flavor.
  • 1/2 cup beef broth Can substitute with chicken broth.
  • 2 teaspoons Worcestershire sauce For added umami.
  • 1 teaspoon dried rosemary For aromatic flavor.
  • 1 teaspoon dried thyme For aromatic flavor.
  • 2 cups frozen mixed vegetables (corn, peas, carrots, green beans) For convenience and texture.

Method
 

Preparation of Mashed Potatoes
  1. Place the peeled and chopped russets in a pot of salted cold water and bring to a boil. Cook until tender, about 15–18 minutes, then drain very well.
  2. Return to the hot pot to evaporate surface moisture. Mash with butter and warm half & half, season with kosher salt and black pepper, then stir in the shredded cheddar until smooth and glossy.
Making Meat & Veggie Filling
  1. Heat vegetable oil in a large skillet over medium-high heat. Add chopped onion and cook until translucent and starting to brown.
  2. Add garlic and cook briefly, then add ground round and season with salt and pepper.
  3. Brown the meat in chunks until well caramelized, then sprinkle flour over the mixture and stir to eliminate raw flour taste.
  4. Fold in tomato paste, deglaze with Guinness, scraping browned bits, then add beef broth, Worcestershire sauce, dried rosemary, and thyme.
  5. Simmer until the sauce reduces and thickens, then stir in the frozen mixed vegetables just to heat through.
Assemble & Bake
  1. Preheat your oven to 400°F (200°C). Spoon the meat and veggie filling into an ovenproof dish in an even layer.
  2. Dollop and spread the cheesy mashed potatoes over the top; roughen the surface with a fork for extra crisping.
  3. Bake until the top is golden and edges are bubbling, about 20–25 minutes; if you want extra browning, broil for 2–3 minutes watching closely.

Notes

For the best texture, avoid overworking the potatoes when mashing. You can prepare the filling ahead and store it before assembling. When freezing, it's best to do so before baking.
