Description

Cheese potato and smoked sausage casserole combines hearty ingredients into a cozy baked dish. Every bite feels rich, filling, and perfect for feeding a hungry family.


Ingredients

Scale

Main Ingredients:

  • 4 large russet potatoes
  • 1 lb smoked sausage
  • 2 cups shredded cheddar cheese

Dairy and Seasoning Ingredients:

  • ½ cup sour cream
  • ¼ cup milk
  • 1 tablespoon butter

Aromatics and Spices:

  • 1 small onion
  • 1 teaspoon garlic powder
  • Salt
  • Pepper

Instructions

  1. Grab your russet potatoes and slice them into thin ¼-inch rounds. Peel the potatoes completely before cutting to ensure a smooth surface.
  2. Heat 1 tablespoon butter in a large skillet over medium heat at 350°F. Cut 1 lb smoked sausage into ½-inch diagonal slices.
  3. Dice 1 small onion into small, uniform pieces. Drop the sausage slices and onions into the skillet, cooking for exactly 6 minutes until sausage edges turn golden brown.
  4. Preheat your oven to 375°F. Coat a 9×13 inch baking dish with cooking spray to prevent sticking.
  5. Mix ½ cup sour cream, ¼ cup milk, 1 teaspoon garlic powder, salt, and pepper in a large mixing bowl until smooth and well combined.
  6. Add potato rounds and cooked sausage mixture to the creamy mixture. Stir gently to coat every slice evenly with the sauce.
  7. Transfer the entire mixture into the prepared baking dish, spreading it into an even layer using a spatula.
  8. Sprinkle 2 cups of shredded cheddar cheese across the top, ensuring complete coverage of the casserole surface.
  9. Cover the dish with aluminum foil and bake at 375°F for 40 minutes, creating a steamy environment for potato cooking.
  10. Remove the foil and continue baking for 15 additional minutes to achieve a crispy, golden cheese topping.
  11. Allow the casserole to rest for 5 minutes after removing from the oven, letting the cheese set and flavors meld together.

Notes

  • Potato thickness matters for even cooking, so slice rounds consistently around 1/4 inch thick to ensure uniform texture throughout the casserole.
  • For a lighter version, swap full-fat dairy with low-fat sour cream and milk, and use turkey sausage to reduce overall calories.
  • Fresh herbs like thyme or chives sprinkled on top can elevate the flavor and add a bright, fresh element to the rich casserole.
  • Allow the casserole to rest 5-10 minutes after baking to help it set and make serving easier without falling apart.
