👩🍳 How to Make Canned Sweet Potato Casserole (Step-by-Step Instructions with Detailed Photos)
Step 1. Preheat the Oven
Preheat your oven to 350 degrees Fahrenheit.
Step 2. Prepare the Sweet Potatoes
Drain any liquid that is inside the canned sweet potatoes. Then put the sweet potatoes (two 15-ounce cans) into a large mixing bowl.
Step 3. Mash the Sweet Potatoes
Mash the sweet potatoes that are in the large bowl with a potato masher until blended.
Tip: If you want the sweet potatoes to be more on the creamy side, you can use an electric hand mixer or stand mixer instead. We used a potato masher this time. A fork will work too, but it’s a little extra work on the wrists.
Step 4. Beat the Eggs
In a small bowl, beat 3 eggs with a fork.
Step 5. Add the Eggs to the Sweet Potatoes
Add the beaten eggs to the large bowl with the mashed sweet potatoes.
Step 6. Mix the Beaten Eggs and Sweet Potatoes
Use a hand mixer, stand mixer, spatula, potato masher, or spoon to mix the beaten eggs with the mashed sweet potatoes until well blended.
Step 7. Melt the Butter
In a small microwave-safe bowl, melt 1/4 cup of unsalted butter in the microwave for about 20 seconds.
Step 8. Add the Evaporated Milk, Lemon Juice, Cinnamon, and Light Brown Sugar
In the bowl with the sweet potato mixture, add the melted butter together with 1/2 of evaporated milk, 1 tablespoon of lemon juice, 1 teaspoon of ground cinnamon, and 1/2 cup of light brown sugar.
Step 9. Mix the Sweet Potato Mixture
Use an electric mixer on low speed to thoroughly blend the added ingredients to the sweet potato filling until thoroughly blended.
Note: You can mix it until smooth, or leave a few little lumps in it to give it a bit of texture, whatever you prefer.
Step 10. Pour the Sweet Potato Mixture into a Baking Pan
Pour the sweet potato mixture into an 8×8-inch square non-stick baking dish. If you use a glass dish it is a good idea to spray the pan with cooking spray or use a pastry brush to brush a couple of tablespoons of butter (melted) on the bottom and sides of the baking dish first before pouring in the sweet potato mixture. The butter gives an extra buttery taste to the bottom of the sweet potatoes. It also helps the sweet potato casserole not stick to the bottom of the pan.
Step 11. Bake the Sweet Potatoes
Put the sweet potatoes in the oven at 350 degrees Fahrenheit. Bake for about 30 minutes or until a toothpick inserted in the middle comes out clean.
Step 12. Toss on the Mini Marshmallows
After 30 minutes, remove the baking pan from the oven. Set it on an oven mitt or hot plate, or just on the stove. Evenly spread 3 cups of mini marshmallows across the top of the baked sweet potatoes.
Step 13. Put the Sweet Potatoes Back into the Oven
After you have the mini marshmallows on top of the sweet potatoes, put the pan back into the oven. Bake for another 10 minutes or until the topping ingredients (the marshmallows) is a light golden brown color.
Step 14. Put the Sweet Potato Casserole Under the Broiler for One Minute
When the 10 minutes of baking time is up, take the casserole out of the oven. Then set the oven to broil. Place the pan under the broiler. Broil the sweet potato casserole for one minute until the marshmallows turn a light brown color. You can skip this step if you think the marshmallows are browned enough.
Very Important: One minute isn’t very long under the broiler, but the broiler is a powerful heat source. So while the sweet potatoes are under the broiler, keep an extra eye on them the whole time. Do not leave the sweet potato casserole and go into the other room. You may need to remove them before the minute is up.
Step 15. Let the Sweet Potatoes Cool Just a Bit
Remove the sweet potato casserole from the oven. Then let it cool at room temperature for a few minutes before serving. It comes out of the oven very hot.
🌟 Recipe Variations
Here are a few sweet potato casserole recipe suggestions you may want to try.
- For a pecan topping and some pecans in the sweet potato mixture, add one-half cup of chopped pecans to the sweet potato mixture and then one-half cup on top of the mini marshmallows before baking.
- Some canned sweet potatoes in the grocery store have canned yams written on the label. These are perfectly fine to use for this recipe.
- You can use fresh sweet potatoes for this recipe. That would involve peeling them (or leaving the peels on), cutting them into chunks, and then boiling them in a large pot of water until fork tender (being able to stick a fork into the sweet potato with ease).
- Or you can bake them, which is much easier to do. Poke a few holes in each sweet potato with a fork, bake them in the oven for 40 to 45 minutes at 400 degrees Fahrenheit (depending on the size), and then remove the skins after baking. The skins come off very easily after baking. You can bake the sweet potatoes ahead of time, like the day before if you prefer to do so. If you do, store them in a container covered with plastic wrap (or a lid if the container you use has one) in the refrigerator until the next day when you are ready to start making this recipe.
- You can add about 1 teaspoon of vanilla extract, 1/2 teaspoon salt, and 1/4 teaspoon of ground nutmeg if you prefer.
Yes, you can freeze this unbaked sweet potato casserole (without the marshmallow topping on it) or leftover sweet potato casserole that has already been baked. If it has already been baked, let it cool, then put it in a freezer-safe airtight container or you can use a double layer of aluminum foil if you know it’s not going to be in the freezer very long.
Otherwise, sweet potato casserole can be in the freezer for about 4 to 6 months if stored properly and also depending on your freezer. Some older freezers can be harsh on frozen foods. If you do the double layer of aluminum foil, take it out of the freezer the night before and let it thaw in the refrigerator. The next day, pop it in the oven, leaving the aluminum foil on it, and bake it until it is nice and hot. Be aware that the longer any food is in the freezer, it will lose its quality, and texture and taste can be compromised.
Cover the sweet potato casserole with a lid or aluminum foil and store it in the refrigerator for 3 to 4 days. After that, eat it or put it in the freezer to serve at another time.
💡 Final Thoughts
