I love potatoes. Really love them. All kinds of potatoes. Baked potatoes, potato skins, french fries. But mashed potatoes and twice baked potatoes are another level for me. Like allllll the way up here. But even better than good ole mashies? This parmesan garlic twice baked potato casserole.

I swear, these are the holy grail of potato goodness. Cheesy, flavorful, creamy, and totally perfect.

Now I can’t take all the credit for this idea. No, my grandma should get some of the credit. When I was growing up, my grandma made stuffed potatoes, which were her version of twice baked potatoes. She used to make them for me at least once a week. Because I loved them, and she loved feeding me.

I remember being a very little girl, probably not much older than Goose is now, and watching her make the stuffing for the potatoes. Because she was old school, she never wrote anything down. She made them totally based on taste and texture. That suited me just fine though because I got to be the official taste tester. She would hand me spoonfuls of the creamy potato filling and ask what they needed. More salt? More pepper? Milk? Butter? Cheese?

I took my job as taste tester very seriously, but they always needed more cheese. Always. And after she added more of the good grated Parmesan cheese to satisfy me, she’d whip them once more with a mixer and then give me the beater to lick.

This parmesan garlic twice baked potato casserole is a nod to her and those amazing stuffed potatoes. These are every bit as good as those stuffed potatoes and as traditional mashed potatoes but so much easier to make. There’s no potato peeling like there is with mashed potatoes, and there’s no stuffing the filling back into potato skins the way my grandma used to. At one point in time, I would have gladly stuffed the filling back in, but these days post Goose, I am all about shortcuts and time savers. Layering all the filling in a casserole dish and topping it with more cheese and butter seemed like a great alternative to me. Her method of doing by taste still works for me. I urge you, if you are going to make this recipe, to taste along the way and make adjustments as you go.

Tips for Making the Perfect Parmesan Garlic Twice Baked Potato Casserole

  • Use Idaho (aka Russet Potatoes or baking potatoes) or Yukon Gold potatoes for best results. Idaho potatoes have a higher starch content so they will be nice and fluffy when you mash them. Yukon Golds are more buttery.
  • Taste, taste, taste! You’ll notice I didn’t include a salt and pepper measurement. I find that because potato sizes vary you’ll need a little more seasoning sometimes. Sometimes you might need more liquid or more butter. Sometimes, you’ll be able to tell by looking at it, but mostly you’ll want to go by taste and mouthfeel.
  • Take the chill off your half and half or cream. Let it come to room temperature before adding it or at the very least warm it up for a few seconds prior to adding it to the potatoes. Adding cold liquid to the potatoes will increase the need for mixing.
  • Do not over mix. Over mixing your potatoes will make the texture sort of gluey. Just don’t do it.
  • If you want to make these for a holiday dinner and cut down on your prep, you can either bake your potatoes ahead of time (just warm them in the oven for a few minutes before you assemble the casserole) or you can use wrap the potatoes in plastic wrap and bake them in the microwave.

    I personally love family recipes. My grandma had a recipe for amazing Chop Suey. After all these years, I still can not recreate her recipe. Maybe it is due to only having it when she vacationed here, or we went to Ohio. Your Parmesan Garlic twice baked potato casserole might just be what I need to get my husband to try a twice baked potato again. I also love that you have the calorie configuration at the bottom of the recipe. That is a great idea for everyone watching their calories come the holiday season.

      Family recipes are the best aren't they? Isn't it funny how some things Grandma just makes best no matter how hard we try?
    • jfletcher
      Ohhhh I hear you on the potato weakness. Mmmmmm, I have never met a potato I didn't like.

    I'm a cheeaselover and i would loe to make this!!!! Parmesan is so much to love!!! Im excited to make this one.
    • jfletcher
      Thanks Nathalie! Doesn't cheese just make everything so much better? I hope you make it and love it.
    • jfletcher
      Mmmmm potatoes are everything. They are a great thing to crave while pregnant. I was all about carbs. But when I was pregnant, my potato craving was Cheddar Cheese pringles. For breakfast.

    Anyone tried freezing this uncooked and reheating? I'd like to make for Christmas and have frozen twice baked potatoes in the skins. Thoughts?
    • jfletcher
      I have not tried that. I'm thinking if you heat up the frozen twice baked potatoes and take them out of their skins it should work just fine. Let me know how it turns out! I'm curious!
  4. Jenna
    This looks so yummy! If I were to make this in advance, would I need to cook longer than 15-18 mins to heat all the way through?
    • jfletcher
      Probably. I'll be honest though, I've never made it ahead because I love it so much I always eat it like RIGHT NOW. I would up the time to maybe 25-30 minutes. Check it frequently though. It should be fine.
  5. Alison
    No where in your directions does it say when to add the 4 pressed garlic cloves. Please advise. Thank you
    • jfletcher
      Hi Alison! Thank you for pointing that out! I can't believe I missed it. You add the garlic in the second step when you are mashing the potatoes. The recipe is updated. I hope you make these. This dish is a favorite in our house. Happy cooking!

So, what do you think ?
