Step‑by‑Step Instructions for Creamy Garlic Butter Sweet Potato Bake

Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven warms up, take a 9×13-inch baking dish and lightly grease it with butter or non-stick spray. This prevents the delicious layers of your Creamy Garlic Butter Sweet Potato Bake from sticking, ensuring that every slice comes out perfectly.

Step 2: Prepare the Cream Mixture
In a medium saucepan over medium-low heat, whisk together cornstarch and heavy cream until smooth. Add in the butter, minced garlic, fresh thyme, kosher salt, and black pepper. Stir gently until the butter melts and the mixture is well combined, avoiding boiling. Once everything is incorporated, set the saucepan aside to keep warm.

Step 3: Slice the Sweet Potatoes
Next, peel and slice your sweet potatoes into thin rounds, approximately 1/8 inch thick. This ensures they bake evenly and become tender. As you layer the sweet potatoes in the greased baking dish, sprinkle each layer generously with salt and pepper for balanced flavor throughout your Creamy Garlic Butter Sweet Potato Bake.

Step 4: Layer the Potatoes
Begin layering the sliced sweet potatoes tightly in the prepared baking dish, forming even, overlapping layers. Ensure that each layer is seasoned with salt and pepper. Once all sweet potato slices are in, it should look vibrant and colorful. This foundation is key to creating that comforting dish everyone will love.

Step 5: Add the Cream Sauce
Carefully pour the warm cream mixture over the layered sweet potatoes. Make sure to cover them evenly, helping each slice to soak up that garlicky goodness. Use a spatula to gently press down on the top layer to ensure all potatoes are submerged in the sauce, allowing for maximum flavor during baking.

Step 6: First Bake
Place the baking dish uncovered in the preheated oven and bake for about 30 minutes. The sweet potatoes will begin to soften, and the sauce will start bubbling. Keep an eye on the dish; the simmering edges are a sign that it’s doing beautifully.

Step 7: Add Cheese Topping
After 30 minutes, remove the dish from the oven and sprinkle a generous layer of Parmesan cheese on top. This will create a deliciously golden crust as it bakes. Place the dish back into the oven for an additional 10 minutes, allowing the cheese to melt and crisp up to perfection.

Step 8: Broil for Extra Crispiness
To achieve an extra crispy topping, switch your oven to broil and cook for an additional 1-2 minutes. Keep a close watch during this step to prevent burning. The cheese should turn a lovely golden brown, adding that irresistible texture to your Creamy Garlic Butter Sweet Potato Bake.

Step 9: Let It Rest
Finally, remove the dish from the oven and let it rest for about 10 minutes before serving. This resting time allows the flavors to settle and the sauce to thicken slightly, making for a perfect texture. Cut into servings and enjoy this comforting dish that’s sure to delight!
