Cheesy Ground Beef and Potato Casserole

Cheesy ground beef and potato casserole was the very first dinner I ever made after moving into my own apartment. I had no clue what I was doing, but I remembered my mom layering sliced potatoes over a bubbling meat filling, and I figured I could pull off something similar. I browned the beef, added whatever spices I had on hand, and topped it with thinly sliced potatoes and cheese. It wasn’t perfect, but it was warm, hearty, and tasted like home. That first bite felt like a small win and I’ve been making it ever since.

Over the years, I’ve refined the recipe and made it my own. It’s now a comfort food staple in my kitchen easy to assemble, endlessly customizable, and always satisfying. Whether I’m cooking for a quiet night in or prepping for a crowd, this casserole never fails to hit the spot. The crispy edges of the potatoes, the savory meat filling, and the golden melted cheese on top create that irresistible combination of textures and flavors that keep everyone coming back for seconds.

Ingredients

Here’s what I use for this recipe. You can always make substitutions if you prefer!

• Ground beef – The hearty base of the casserole, full of rich flavor and protein.
• Onion – Adds savory sweetness and depth to the beef layer.
• Garlic – Brings a warm, aromatic kick to the meat mixture.
• Tomato paste – Gives the beef a concentrated, tangy flavor boost.
• Worcestershire sauce – Adds umami and complexity to the filling.
• Potatoes – Thinly sliced and layered on top, they bake into tender, golden perfection.
• Milk – Helps soften the potatoes while baking.
• Cheddar cheese – Melts beautifully over the top and adds sharp, creamy richness.
• Olive oil – Used for sautéing and brushing on the potatoes for a golden finish.
• Salt and pepper – Essential for seasoning each layer.
• Fresh parsley – Adds a fresh, colorful garnish just before serving.

Tools You’ll Need

• Skillet – Perfect for browning the ground beef and sautéing the aromatics.
• Casserole dish – Ideal for layering the beef and potato mixture and baking evenly.
• Sharp knife or mandoline – For slicing the potatoes thin and uniform.
• Cutting board – For prepping your ingredients easily and safely.
• Measuring cups and spoons – To keep ingredient portions consistent.
• Spatula or spoon – For mixing and layering the beef filling.
• Aluminum foil – Helps the casserole cook evenly without over-browning.
• Oven mitts – Always important for handling hot dishes safely.

Instructions

Step 1: Preheat the Oven

I start by preheating the oven to 375°F (190°C) while I prep the other ingredients.

Step 2: Cook the Ground Beef

In a large skillet, I heat a little olive oil and sauté chopped onion until softened. Then I add the ground beef, cooking until browned and crumbly. I stir in garlic, tomato paste, Worcestershire sauce, salt, and pepper, and let it simmer for a few minutes.

Step 3: Prep the Potatoes

Using a sharp knife or mandoline, I slice the potatoes thinly about 1/8-inch thick. I set them aside while the meat mixture finishes cooking.

Step 4: Assemble the Casserole

I spoon the beef mixture into the bottom of a greased casserole dish and spread it out evenly. Then I layer the sliced potatoes on top in overlapping rows for a nice visual effect.

Step 5: Add Milk and Cheese

I pour a bit of milk over the potatoes to help them soften during baking. Then I sprinkle a generous layer of shredded cheddar cheese over the top.

Step 6: Bake

I cover the dish with foil and bake for 35–40 minutes. Then I remove the foil and bake for an additional 10–15 minutes until the potatoes are fork-tender and the cheese is bubbly and golden.

Step 7: Garnish and Serve

Once it’s out of the oven, I let it sit for about 5 minutes before sprinkling chopped parsley on top and serving.

Tips

I always recommend slicing the potatoes as evenly as possible so they cook through at the same rate. If you want an extra cheesy version, you can add a second layer of cheese between the beef and potatoes. For added flavor, sometimes I mix a bit of cream or sour cream into the milk before pouring it over the top. And if you want to save time, partially cooking the potato slices before assembling can help speed up the bake time.

Ways to Serve

This cheesy ground beef and potato casserole works beautifully as a standalone meal, especially when served with a crisp green salad or steamed vegetables. It’s also a comforting side dish for larger spreads like holiday dinners or potlucks. I’ve even served it with a fried egg on top for a hearty breakfast twist the next morning. Its rich flavors and cozy texture make it a versatile dish that fits into just about any mealtime scenario.
