Cheesy Potato and Ground Beef Casserole Step-by-step instructions

Before you start

Before beginning the assembly, ensure the work surface is clean and organized. Peel all of the potatoes and slice them into uniform, thin rounds. If using a mandoline, take care when handling the blade. Prepare the ground beef by browning it in a skillet until fully cooked, then drain the grease thoroughly.

Have the cheese measured and the cherry tomatoes halved so that the layering process can proceed without interruption. Having all components ready at room temperature before you start the layering process is crucial for maintaining the rhythm of the preparation.

Instructions

Browning the beef

1. 1Prepare the beef
   Heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it into crumbles with a spatula, until browned and cooked through. Ensure the internal temperature reaches 160°F (71°C) to guarantee safety. Drain any excess grease from the pan and set the meat aside.
   Look for The beef should be fully browned with no pink remaining.
   Safe temperature 160°F (71°C) internal temperature (ground meat)
   Tip Use a lean ground beef blend to minimize the amount of fat that needs to be drained.

The ground beef should be deeply browned and fragrant, with all pink color completely gone from the center of the meat crumbles. The texture will be slightly crisp from the heat of the skillet, and the fat rendered during the process should be mostly removed. Once the beef reaches a safe internal temperature of 160°F (71°C), it is ready to be incorporated into the casserole layers.

Assembling the layers

2. 2Layer the casserole
   Preheat your oven to 375°F (190°C). In a 9x13 inch baking dish, begin by arranging a layer of the thinly sliced potatoes on the bottom. Add a layer of the cooked ground beef over the potatoes. Repeat the layers until all ingredients are used, finishing with a final layer of potatoes.
   Look for Create uniform layers to ensure even cooking throughout the dish.
   Tip Slice potatoes very thinly to ensure they become tender within the baking time.

At the end of this phase, the baking dish should be neatly filled with alternating layers of potatoes and ground beef. The surface should look uniform, with the potatoes neatly overlapping to create a solid base. Ensure that the layers are distributed evenly across the bottom of the dish to prevent any spots from being too dry or too crowded during the baking process.

Baking to perfection

3. 3Bake and serve
   Cover the dish with foil and bake for 30 minutes. Remove the foil, add the cherry tomatoes and shredded cheese on top, and return to the oven for an additional 15 minutes or until the cheese is melted and bubbly. Let the dish rest for 10 minutes before serving to allow the layers to settle.
   Look for The cheese should be golden brown and bubbling at the edges.
   Tip Letting the casserole rest is essential for clean serving portions.

The final casserole should have a vibrant, golden-brown cheese topping that bubbles slightly around the edges. When you insert a fork, it should slide through the potato layers without any resistance, indicating they are perfectly tender.

The cherry tomatoes will be slightly softened, releasing their juices into the layers below, and the entire dish will be aromatic and ready to rest before serving.

Common mistakes

A common mistake is slicing the potatoes too thickly, which prevents them from cooking through in the allotted time. Ensure your slices are approximately 1/8 inch thick. Another error is failing to drain the ground beef properly, which can lead to a greasy casserole where the flavors become muddled.

Additionally, skipping the resting period can cause the casserole to fall apart when you try to scoop it onto plates. Finally, ensure the oven is fully preheated before putting the dish in to ensure consistent cooking temperatures from the start.

How to tell it’s done

The casserole is done when the potatoes are fork-tender throughout, which you can test by inserting a knife into the center of the dish. The cheese should be completely melted and golden brown, bubbling at the edges of the baking dish.

Because the ground beef was pre-cooked to 160°F (71°C), the main indicator of doneness is the texture of the potatoes and the appearance of the cheese topping. Always allow the dish to rest for 10 minutes to ensure the structure is stable enough to serve.
