Introduction

The Hamburger Potato Casserole is a timeless staple of the “one-pan” culinary tradition. Historically, these dishes gained popularity for their ability to stretch a small amount of meat into a filling, nutrient-dense meal for a large family. From a culinary perspective, this dish is a study in convection cooking. By layering thinly sliced potatoes with seasoned ground beef and a creamy binder, we create a self-steaming environment where the moisture from the vegetables and the fats from the beef emulsify into a rich, gravy-like sauce.

The addition of green chili and garlic powder provides a modern lift to the traditional flavor profile, cutting through the richness of the cheddar cheese and cream of mushroom soup. This casserole is the ultimate “emergency meal”—simple to prep, incredibly satisfying, and even better the next day when the flavors have had time to fully marry. Whether you’re feeding kids or looking for a cozy winter dinner, this recipe delivers a nostalgic “hug in a bowl.”

Ingredients

Consistency in potato slicing is the most important factor for even cooking. Using a mandoline or a very sharp chef’s knife is recommended.

• 1/2 pound Ground Beef: Lean (90/10) works best to prevent the casserole from becoming oily.
• 4 large Russet Potatoes: Thinly sliced (about 1/8 inch thick). Russets are preferred for their high starch content.
• 1 medium Onion: Chopped (yellow or white onions provide the best sweetness).
• 2 cups Shredded Cheddar Cheese: Freshly shredded for a superior melt.
• 1 can (10.75 oz) Cream of Mushroom Soup: The savory “glue” of the dish.
• 3/4 cup Milk: To thin the soup and help steam the potatoes.
• 1 tsp Garlic Powder: For aromatic depth.
• 1 tsp Green Chili (Optional): For a subtle, smoky warmth.
• 2 tablespoons Olive Oil: For sautéing the aromatics.
• Salt and Pepper: To taste.
• Fresh Parsley: Chopped for a bright, herbal garnish.
