Garlic Butter Sweet Potato Bake Ingredients
For the Bake
• Sweet Potatoes – The foundation of this dish; choose firm, orange-fleshed varieties for maximum sweetness.
• Garlic – Minced for an aromatic punch; fresh garlic enhances the buttery flavor brilliantly.
• Butter – Use unsalted for better control over seasoning; it forms the rich base of your garlic sauce.
• Heavy Cream – Creates a wonderfully creamy texture; substitute with half-and-half for a lighter option.
• Thyme – Adds a fragrant herbal note that complements the garlic; feel free to swap for rosemary or oregano.
• Kosher Salt & Black Pepper – Essential for flavor enhancement; season each layer of sweet potatoes for a well-rounded taste.
• Parmesan Cheese – Adds a golden, bubbly topping that elevates the dish; cheddar can be a delightful alternative.
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). While the oven warms, grab a 9×13 inch baking dish and lightly grease it with butter or non-stick spray to prevent sticking. This ensures your Garlic Butter Sweet Potato Bake will come out smoothly after baking, making every serving a delight.
Step 2: Whisk the Sauce
In a medium saucepan, combine heavy cream with a sprinkle of cornstarch over medium-low heat. Whisk the mixture continuously until it’s warm and begins to thicken slightly, about 3-5 minutes. Then, add in the butter, minced garlic, thyme, kosher salt, and black pepper. Stir until the butter melts and the garlic becomes fragrant, taking care not to let it boil.
Step 3: Slice the Sweet Potatoes
Wash and peel the sweet potatoes before slicing them into thin, even pieces, aiming for about 1/8-inch thickness. A mandoline slicer works perfectly for this task, ensuring uniformity that allows the sweet potatoes to cook evenly. Layer these beautiful slices evenly across the bottom of your greased baking dish to form a solid base for your dish.
Step 4: Pour the Sauce
Once your sauce is ready, pour it generously over the layered sweet potatoes. Use a spatula to gently coat the slices, making sure each piece is enveloped in that rich garlic butter cream. This step is crucial for achieving a flavorful Garlic Butter Sweet Potato Bake, so ensure all potatoes are well-covered.
Step 5: Initial Baking
Cover the baking dish tightly with aluminum foil to trap the steam. Place it in the preheated oven and bake for about 30 minutes. This initial covered baking phase softens the sweet potatoes, allowing them to become tender and absorb the flavors of the garlic butter sauce beautifully.
Step 6: Add Cheese and Finish Baking
After 30 minutes, carefully remove the foil and sprinkle the grated Parmesan cheese evenly over the top of the bake. Return the dish to the oven for an additional 10 minutes, allowing the cheese to melt and turn golden and bubbly. For an extra crisp layer, broil for 1-2 minutes, watching closely to avoid burning.
Step 7: Rest and Serve
Once achieved the desired golden-brown topping, carefully remove the Garlic Butter Sweet Potato Bake from the oven. Let it rest for about 10 minutes before slicing to enhance the presentation and make serving easier. This resting time allows the layers to set, creating a more cohesive dish that’s sure to impress your guests.

Storage Tips for Garlic Butter Sweet Potato Bake
Fridge: Store leftovers in an airtight container for up to 4 days. The garlic butter sauce may thicken but will maintain its comforting flavor when reheated.
Freezer: Portion out the bake and freeze for up to 3 months. Wrap tightly in plastic wrap and aluminum foil to prevent freezer burn, ensuring your Garlic Butter Sweet Potato Bake stays delicious.
Reheating: To reheat, cover with foil and bake in a 350°F (175°C) oven for 15-20 minutes or microwave portions, adding a splash of cream to restore creaminess if desired.
