Ingredients

2 pounds russet potatoes peeled & diced, see note
1 pound lean ground beef
1 medium onion chopped
4 cloves garlic minced
1 cup frozen mixed vegetables
Salt & pepper to taste, see note
1 (10.5 ounce) can condensed cream of mushroom soup
1 cup milk 2% recommended
1/2 cup sour cream
1 tablespoon Worcestershire sauce
1 teaspoon Italian seasoning
2 cups shredded cheddar cheese divided

Instructions

Preheat your oven to 400F and move the rack to the middle position.
Add the potatoes to a greased 9x13 casserole dish.
Add the beef and onions to a skillet and cook, breaking the meat up with your spoon as you go along, until browned (about 8-10 minutes). Drain excess fat if needed.
To the skillet, add in the garlic and frozen mixed vegetables and cook for another 2-3 minutes, stirring often. Season with some salt & pepper and transfer the mixture to the casserole dish.
In a medium prep bowl, mix the cream of mushroom soup, milk, sour cream, Worcestershire sauce, Italian seasoning, and half of the cheddar cheese together.
Pour the sauce mixture over top of the beef and potatoes, then stir and arrange it in an even layer.
Cover the casserole tightly with foil and bake for 45 minutes.
Take the foil off, sprinkle the remaining cheese on top, and bake uncovered for another 10-15 minutes or until the cheese has melted and the potatoes are tender.
Let it sit for 5-10 minutes prior to serving, then season with extra salt & pepper as needed.

Notes

Aim for the potatoes to be cut into approx. 1/3" cubes. If they're bigger than 1/2", you will need to bake the casserole for longer so they cook through.
This recipe is quite kid friendly as written. You can kick up the flavor a bit by subbing the salt & pepper for Tony's seasoning. Seasoning salt works great too. Or try serving with some hot sauce!
