Step‑by‑Step Instructions for Garlic Butter Sweet Potato Bake
Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). Grease a 9×13-inch baking dish with unsalted butter or nonstick spray to ensure the sweet potatoes don’t stick. This step sets the stage for your creamy Garlic Butter Sweet Potato Bake, creating a layer of richness from the start.
Step 2: Make the Garlic Butter Sauce
In a medium saucepan over medium-low heat, whisk cornstarch into heavy cream until smooth. Gradually add unsalted butter, minced garlic, fresh thyme, kosher salt, and black pepper. Stir this mixture continuously until warmed through but not boiling, allowing the flavors to meld beautifully, which will enhance your bake.
Step 3: Slice Sweet Potatoes
Thinly slice your orange-fleshed sweet potatoes into uniform 1/8-inch rounds. Ensuring consistent thickness will promote even cooking and a creamy texture. As you layer these slices in the prepared baking dish, imagine how each piece will soak up that luscious garlic butter sauce.
Step 4: Layer and Pour
Once the sweet potato slices are arranged in the baking dish, pour the hot garlic butter sauce evenly over them. Ensure every slice is enveloped in the flavorful mixture for maximum richness. Cover the dish tightly with aluminum foil and place it in the preheated oven. Bake for 30 minutes until the sweet potatoes are tender.
Step 5: Add Cheese and Brown
After 30 minutes, carefully remove the foil and sprinkle grated Parmesan cheese over the top of the sweet potatoes. Return the dish to the oven and bake uncovered for an additional 10 minutes. You’ll know it’s done when the cheese is golden and bubbly, creating a delightful crust on your Garlic Butter Sweet Potato Bake.
Step 6: Broil for Extra Crisp
For an added layer of deliciousness, broil the dish for 1-2 minutes, keeping a close eye to prevent burning. This quick step will create an irresistible, crispy topping that complements the creamy layers beneath, enhancing the overall texture of your bake.
Step 7: Rest Before Serving
Once out of the oven, allow the Garlic Butter Sweet Potato Bake to rest for about 10 minutes. This resting period thickens the sauce and makes serving easier, allowing the flavors to settle in for better enjoyment. Your comforting dish is now ready to impress!

Expert Tips for Garlic Butter Sweet Potato Bake
- Slice Evenly: Ensure sweet potatoes are cut into consistent 1/8-inch slices to allow for even cooking and a creamy texture throughout your Garlic Butter Sweet Potato Bake.
- Don’t Rush the Sauce: Allow the garlic butter sauce to heat gently over medium-low. Quick cooking can lead to burnt garlic flavors, compromising the dish’s richness.
- Layer Wisely: To enhance flavor, season each layer of sweet potatoes with a generous amount of salt and pepper, allowing the spices to penetrate the potatoes fully.
- Cover Initially: Always cover the dish with foil for the first 30 minutes of baking. This traps steam, ensuring the sweet potatoes cook tenderly before browning.
- Check for Doneness: Keep an eye on your bake as it cooks, especially in the final stages—golden cheese is the sign of perfection, but too much time can lead to burning.
