Many recipes for Loaded Potato Casserole call for instant mashed potatoes, but I like to use my Easy Mashed Potatoes. They are so quick to make, they will be done by the time the meatloaf layer is done cooking. If you still want to use instant mashed potatoes, I’ve included a quick recipe below to give them lots of flavor.

This is a great one pan meal (after it has been prepped) that travels well so you can take it for potlucks, or make ahead of time for an easy meal for the babysitter to pop in the oven. We like to serve it with Dinner Rolls and a side of Green Beans for well-rounded meal during the week.

Can you make this ahead of time?

Follow the recipe as usual but do not broil. Cover tightly with plastic wrap and foil before storing in the refrigerator for up to 3 days. To serve, remove plastic wrap and cover again with foil. Bake at 350 degrees for 10 minutes or until warm. Switch to broil for 3 to 5 minutes to brown cheese.



Can you make Loaded Potato Meatloaf Casserole in a Slow Cooker?

Start by baking meatloaf layer as usual, or cook ingredients (except for egg) in a skillet like a Sloppy Joes. Transfer cooked meat to the slow cooker. Mix 1/2 bacon and fried onions with mashed potatoes. Spread potatoes over meat, then cover and cook on low for 5-6 hours. Sprinkle remaining bacon and onions on top, then cheese. Cover and cook 5-10 minutes until cheese is melted.

    • Ground Meat: Substitute ground turkey, chicken, pork, or even lamb for for a different flavor. Using ground lamb would make this a simple, delicious Easter Dinner.
    • Veggies: Add a layer of cooked frozen veggies like corn or peas and carrots, over the meatloaf layer. Or add a layer of sautéed mushrooms, onions, or bell peppers. 
    • Southwestern: Season your ground beef with Taco Seasoning. Stir in a can of drained green chiles either into your meat or your mashed potatoes and top with Monterey Jack cheese. Serve with sour cream and Salsa.
    • Potatoes: Instead of Idaho potatoes, try using Mashed Sweet Potatoes or mashing other favorites like Yukon Gold or Red Skin potatoes.
    • Low Carb: Make a Keto Loaded Potato Meatloaf Casserole with a quick and easy mashed cauliflower. Microwave 1 large bag of frozen cauliflower in a large bowl until hot. Add 8 ounces softened cream cheese and blend until mashed potato consistency.



  • Serve: This casserole will stay good at room temperature for up to 2 hours.
  • Store: Wrap tightly or transfer to an airtight container before storing for up to 3 days in the refrigerator. 
  • Freeze: Cool the casserole completely before freezing in a sealed container. Allow to thaw overnight in the fridge before reheating.
