Step‑by‑Step Instructions for Cheesy Sweet Potato Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This temperature ensures that your Cheesy Sweet Potato Casserole will bake perfectly, allowing the cheese to melt beautifully while creating a deliciously bubbly top. Make sure your oven is fully heated before placing the casserole inside for the best results.
Step 2: Prepare the Sweet Potatoes
Peel and chop the sweet potatoes into even chunks for uniform cooking. Place them in a large pot, cover with water, and bring to a gentle boil over medium heat. Allow the sweet potatoes to cook for about 15-20 minutes, or until they are tender enough to pierce easily with a fork.
Step 3: Mash the Sweet Potatoes
Once tender, drain the sweet potatoes and return them to the pot. Add milk, butter, salt, and pepper, then mash the mixture until smooth and creamy. This step is crucial as it creates the luscious base for your casserole. Aim for a velvety texture without over-mixing to avoid a gummy consistency.
Step 4: Assemble the Casserole
Spread the mashed sweet potato mixture evenly in a greased baking dish, smoothing the top with a spatula. This layer serves as the foundation of your Cheesy Sweet Potato Casserole, providing both flavor and texture. Make sure it is evenly distributed to ensure even baking.
Step 5: Add the Cheese
Generously sprinkle shredded cheddar cheese over the sweet potato layer, ensuring every corner is covered for maximum cheesiness. The cheese will melt into the casserole as it bakes, adding a rich flavor and gooey texture that complements the sweet potatoes beautifully.
Step 6: Bake to Perfection
Place the assembled casserole in the preheated oven and bake for 20-25 minutes. Keep an eye on it as it cooks; you’re looking for the cheese to be melted, bubbly, and just lightly browned on top. This golden crust indicates that your Cheesy Sweet Potato Casserole is ready to come out and be enjoyed.
Step 7: Let it Rest
Once out of the oven, let the casserole sit for about 5 minutes before serving. This resting time allows the flavors to meld together and makes it easier to serve. Your Cheesy Sweet Potato Casserole will be warm and inviting, ready to be a comforting addition to your meal!

Cheesy Sweet Potato Casserole Recipe FAQs
How do I choose sweet potatoes for my casserole?
Absolutely! Look for sweet potatoes that are firm, with smooth skin free of dark spots or blemishes. Ideally, select those that are a uniform size for even cooking. When cooking with butternut squash as a substitute, choose one that feels heavy for its size and has a rich orange color.

To keep your leftovers fresh, transfer them into an airtight container and refrigerate. They should last for up to 3 days. If you want to keep them longer, you can freeze the casserole wrapped tightly in plastic wrap and aluminum foil for up to 3 months!
Can I freeze the Cheesy Sweet Potato Casserole?
Yes! To freeze, first let the casserole cool completely. Then, wrap it tightly with plastic wrap, followed by aluminum foil for an airtight seal. When you’re ready to eat, thaw it overnight in the fridge and bake at 350°F (175°C) for 25-30 minutes until warmed through. This way, you can enjoy that cheesy goodness any time.
What if my casserole turns out too gummy?
If your Cheesy Sweet Potato Casserole has a gummy texture, don’t worry—this can happen if you over-mix the sweet potatoes.

When adding butter and milk, mix gently until just incorporated to keep that creaminess without the gumminess!
Is this recipe suitable for vegetarians?
Very! This Cheesy Sweet Potato Casserole is vegetarian-friendly as it contains no meat.
