Step-by-Step Instructions
1. Brown the Ground Beef
In a skillet over medium heat, cook the ground beef until fully browned. Drain excess grease.
This step adds flavor and keeps the casserole from becoming oily.
2. Prepare the Sauce
In a bowl, mix the cream of mushroom soup and milk until smooth and creamy.
3. Layer in the Slow Cooker
Lightly grease your slow cooker.
Layer half of the sliced potatoes on the bottom.
Top with half the cooked ground beef.
Pour some of the soup mixture over the layer.
Repeat with remaining potatoes, beef, and sauce.
Do not stir.
4. Cook Low & Slow
Cover and cook:
-
LOW for 6–7 hours
-
or HIGH for 3–4 hours
The potatoes should be fork-tender and the sauce thick and creamy.
5. Let It Rest
Allow the casserole to sit for 10–15 minutes before serving. It thickens beautifully as it rests.
