Holly’s Recipe Highlights
- Flavor: Rich and comforting, this casserole combines creamy, buttery potatoes with sharp cheddar and smoky bacon for big flavor in every bite.
- Skill Level: Just slice the potatoes in half, bake, scoop, top, and bake again. So easy!
- Tools: A potato masher is a handy tool for getting perfectly mashed potatoes.
- Serving Suggestions: Leftover baked potatoes inspired me to make this recipe. And so, like all baked potatoes, it pairs so well with meatloaf, grilled steaks, and most holiday meals.
What You’ll Need
- Potato Base: Russet potatoes are ideal because they mash easily and create a light, fluffy texture. Yellow or red potatoes work too, and stay nice and creamy when cooked. For extra richness, mash the warm potatoes with butter, cream cheese, and sour cream.
- Mix-Ins: This is where all the loaded potato flavor comes in. Use sharp cheddar for a bolder flavor or mild cheddar for a creamier dish, and shred your own so it melts smoothly. Cook the bacon until crisp, then crumble some into the potatoes and save a little for the top. Stir in green onions, herbs, and your favorite seasonings for more flavor and a bit of color in every scoop.
- Toppings: Finish with more cheese, crispy bacon, and a sprinkle of green onions for a classic loaded potato look.
- Variations: Swap the cheddar for pepper jack for a spicy twist. Stir in roasted garlic, cooked ham, or leftover chicken to make it a meal.

This dish is requested at all my barbeques!!
Can make these ahead of time and then reheat in the crockpot
I think it should work just fine, Amber! I would suggest about 2-2 ½ hours on low, stirring after an hour (add the cheese topping after stirring). Once they’re heated through, you can turn them to warm if they’re ready early. You’ll want to make sure that you use a smaller slow cooker (4qt) so it’s not too thin and they don’t dry out.
perfect recipe.
Is this something that can be created a week or two in advanced and frozen until ready for use?
Absolutely, I make them ahead of time and freeze, you can bake right from frozen. I do approximately 350°F for about 45-55 minutes.
I’ve made this exactly as written, quite a few times and always get compliments. Thank you for another great recipe!
If I make this 2 days before I cook it, how long are the leftovers good for? We love this recipe and so I make it quite often but always cook it the same day.
Hi Jessica, I would recommend only storing leftovers for an additional day before freezing them.
Delicious! I made too much (well I could eat the whole pan but…) – can I freeze the leftovers? Please say yes
So glad you loved it Nancy! The leftovers can be frozen. I would recommend thawing in the fridge overnight.
I wanna make this for Christmas dinner. would you know how much potatoes by weight/grams or pounds maybe? thanks so much
Hi Esther, this recipe uses about 3 ½-4 lbs. Enjoy the recipe!
