How to Make Twice Baked Mashed Potatoes

Wash and peel russet potatoes. Dice potatoes into small chunks and store in cold water to keep them from turning brown. Place potatoes in a large stock pot and cover with cold water.

Bring water to a boil, then reduce heat to medium low. Cover pot and cook potatoes until soft...about 15-20 minutes. When tender, drain potatoes in a colander and place in a large mixing bowl filled with cold water.

Recipe FAQS

Why are these called Twice Baked Mashed Potatoes?

Some recipes call for baking the potatoes and scooping out the pulp which is another way to make this casserole. But the easy way is to boil and mash potatoes, mix with delicious ingredients, then bake to the perfect consistency. So basically, the casserole is being cooked TWICE, which explains how it got its name.

Can the eggs be omitted?

Yes, if you are allergic to eggs or can't eat them, they can be omitted from this casserole. I like adding eggs because it makes the casserole rise and be more fluffy. However, it tastes great with or without eggs.

Do I have to peel the skins?

I've made this casserole both ways and I prefer it to be smooth and creamy. But if you love the taste of potato skins, feel free to leave them on and enjoy! Prep will definitely be faster without having to peel the skins.

Can this casserole be made ahead?

Absolutely! This mashed potato casserole is perfect for making ahead, which saves time and space if you're planning a holiday meal. Just assemble as directed and cover with a lid or wrap with aluminum foil. Keep in the refrigerator up to 2 days before baking.

Storage and Freezing

LEFTOVERS: store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or in a 350ºF oven until heated throughout. 

FREEZING: since there is a high content of cream in this recipe, it doesn't freeze well. It tends to separate after it thaws and doesn't hold its original shape.
