Ingredients

• 2 cups shredded leftover pot roast (the more tender, the better—no one likes a chew-fest)
• 1 cup sour cream (full-fat for the win, because we’re not here to skimp)

Guess what? Your fridge is about to become the unsung hero of your week with this Leftover Pot Roast and Potato Casserole. It’s the ultimate ‘second act’ for your leftovers, turning them into a dish that’ll have everyone asking for seconds.

Ingredients

• 2 cups shredded leftover pot roast (because who has time to cook from scratch?)
• 3 cups diced potatoes (I’m team Yukon Gold for their buttery texture)
• 1 cup shredded cheddar cheese (sharp cheddar, because mild is just a suggestion of cheese)
• 1/2 cup sour cream (full-fat, because we’re not here to skimp)

3. In a large bowl, mix the shredded pot roast, sautéed potatoes, sour cream, milk, garlic powder, salt, and pepper until everything is well combined (tip: this is where you taste and adjust the seasoning, because you’re the boss of your casserole).
4. Transfer the mixture to a greased baking dish and sprinkle the shredded cheddar cheese on top (tip: for an extra crispy top, broil for the last 2 minutes of baking).
5. Bake for 20-25 minutes, or until the cheese is bubbly and slightly golden (visual cue: when it looks too good to wait, it’s probably ready).

When it comes out of the oven, this casserole is a glorious mess of creamy, cheesy, beefy goodness. Serve it with a side of green salad to pretend you’re being healthy, or just dive in with a fork—no judgment here.
