Can you believe Thanksgiving is only a week away?! It’s crazy! And it’s time to start planning out your meal if you haven’t already.

Last week I shared one of my Thanksgiving essentials – Cheesy Hash Brown Casserole. Today I share with you another true essential. Sweet Potato Casserole with marshmallows. No nuts here, my friends. I like it sweet, remember? Without this, my Thanksgiving feast is pretty much over.

For the past few years I’ve been working on perfecting these sweet potatoes. They truly are my favorite and they must be just the right combo of enough sweetness, marshmallows and the right consistency. Not too runny. I could eat these for every meal, every day. Even for dessert.

So if you don’t already have a recipe you love, or even if you do, these would be some good ones to try. Seriously. I practically lick the spot on the plate where these were. Just to get every last bite (or lick).

4. Bake at 350 degrees for 18-20 minutes.

    My daughter made this for a “Friendsgiving” get together. We didn’t have a lot of time so we looked for a recipe using canned sweet potatoes. It was a BIG hit. Delicious! Just the right amount of nutmeg and cinnamon. 5 stars!

    Hi, love to make this but can’t get canned sweet potatoes in the uk. How many uncooked sweet potatoes would I need, and do I just bake them first? With anticipation!!!

    1. Life, Love and Sugar

      Hi Samantha! I’ve never used regular sweet potatoes for this recipe, so it’s hard to say. I googled for you and the answer I found is 3 large sweet potatoes. I’m not sure how accurate it is, but you could try it. And yes, you’d want to bake them until tender first.

    Looks so yummy!! Sweet potato casserole is delicious…but I think green bean casserole has to be my all time favorite Thanksgiving food group lol, with LOTS of extra french fried onions. I like to add a little bit of sugar as well to add a sweet note to it as well 🙂

      Green Bean Casserole is another requirement of mine. I usually add a little worchestire sauce and hot sauce though to give it a little kick. I’ve never thought to add sugar and make it sweet before. What a great idea!

        I add worcestershire sauce to mine too!! The hot sauce sounds good! I love spicy things almost as much as I love sweet things!
