Twice baked potatoes in casserole form!

Today’s recipe is one I tried last month knowing it would be great for fall and especially for a Thanksgiving side dish. It’s a Twice Baked Potato Casserole that was DELICIOUS!! If you have ever had Twice Baked Potatoes before then you can imagine how a casserole version would be so good.

The family agreed that this easy casserole dish is just as good or even better than twice baked potatoes. I agree it was great but still can’t decide which is better. I love that both are easy to make, but loved the simplicity of throwing it all in a dish as opposed into each potato skin. I also have a thing for red potatoes so this casserole is a new favorite.

As you could venture to guess, this casserole is called twice baked because the potatoes get baked twice. Baking them the first time allows them to be cooked all the way and to be cooked until soft. We have a feeling you will love this recipe as much as we do!

How to make Twice Baked Potato Casserole:

Potatoes: I like using red potatoes for this casserole because they keep their shape and texture a little better than russet potatoes. Another reason I like using red potatoes is that you do not need to peel them first. However, you can use russet potatoes if that’s what you have on hand or prefer. 

This is a great recipe to make when you have leftover baked potatoes. You can also use boiled potatoes, If you’re in a hurry you can even use cubed freezer potatoes. 

For this recipe, we cut them into 1 inch cubes after being baked. We also put together a mixture of sour cream, salt, pepper, bacon and cheese. Then this is layered in a 9×13 dish with the potatoes.

The casserole gets baked again allowing for the cream mixture to get heated through and the result is a cheesy, hearty potato casserole that everyone goes nuts for!

Change it Up + storing

Variations: There are several ways to change up this casserole. Here are a few ideas…

  • Replace or mix the bacon with ham cubes or sausage chunks.
  • Mix in veggies corn, broccoli florets or diced bell peppers would all add a delicious twist.
  • Sour cream: greek yogurt is a close substitute. You can also use an equal amount of heavy whipping cream  mixed with 1tbsp lemon/lime juice per cup used.
  • Add or subtract the amount of sour cream used to your liking. 

Leftovers: Divide leftovers into individual containers, keep in the fridge for 1-2 days. 

Reheat: If you are only reheating an individual portion you can use the microwave. Heat in 30 second increments until hot. For larger portions preheat the oven to 350°F for 20-30 minutes depending on the size until hot.

Ahead of time: You can make this ahead of time through step 4. Cover and store in the fridge for 1-2 days before baking a second time and serving. For longer storage be sure to use a freezer safe baking dish. Wrap with plastic wrap and again with foil, Store in the freezer for up to 2 months. Thaw overnight on the fridge before baking a second time.

  1. I made this tonight and I think 3 cups of sour cream was too much don’t get me wrong it wasn’t bad but the sour cream was overwhelming, I would just use less next time! Thanks for sharing!

    Is there a sub for sour cream and it can’t be yogurt either. I don’t like either and I am a super taster so I would taste it. Otherwise, I would love to make this. Could I just leave it out altogether?

    1. I think it would definitely turn out different. The sour cream makes it creamy. You can try substituting 3/4 c buttermilk with 1/4 c butter. If that doesn’t work, you can always google & find a substitute that you like. Hope that helps!!
