Ingredients about Homemade Garlic Butter Sweet Potato Bake
To make your Homemade Garlic Butter Sweet Potato Bake, gather the following ingredients:
- 1 tsp cornstarch
- 1 1/2 cups heavy cream
- 1/2 cup (1 stick) butter
- 5 cloves garlic, finely minced
- 1 tbsp chopped fresh thyme
- Kosher salt, to taste
- Freshly cracked black pepper, to taste
- 3 lb sweet potatoes, peeled and sliced thin (about 1/8-inch thick)
- 1/3 cup fresh parmesan cheese, grated
How to Make Homemade Garlic Butter Sweet Potato Bake Directions
Creating this delicious dish begins with some simple prep work. First, you’ll want to preheat your oven to 375°F (190°C). While your oven is heating, grab a large saucepan and melt the butter over medium heat. Add in your finely minced garlic and sauté for about a minute—be careful not to let it brown, as this can lead to a bitter taste. Once the garlic is fragrant, sprinkle in cornstarch and stir to form a roux.
Slowly pour in the heavy cream, continuously stirring to combine everything smoothly. As the mixture thickens, season it generously with kosher salt, freshly cracked black pepper, and fresh thyme. Allow this mixture to simmer for a couple of minutes before removing it from the heat.
Now it’s time for the star of the show: the sweet potatoes! Using a mandoline or a sharp knife, slice your sweet potatoes into 1/8-inch thick rounds. This slicing method ensures that every piece cooks evenly, giving you that perfect creamy texture.
In a large baking dish, start layering the sliced sweet potatoes. Pour a portion of the creamy garlic butter mixture over the top, ensuring each layer is evenly coated. Repeat this process until you have used all your sweet potatoes, finishing off with a final layer of the creamy mixture. To add a touch of elegance, sprinkle the grated parmesan cheese generously over the top.
Cover the baking dish with aluminum foil and bake for about 45 minutes. This will allow the sweet potatoes to absorb all that delicious flavor and soften beautifully. For the last 15 minutes of baking, remove the foil to let the top crisp up and turn golden brown. When it’s out of the oven, allow it to cool slightly before serving to let the flavors meld perfectly.
How to Serve Homemade Garlic Butter Sweet Potato Bake
Serving your Homemade Garlic Butter Sweet Potato Bake is simple and delightful. First, use a sharp knife to cut the bake into even squares or rectangles, allowing each serving to maintain its shape. You can serve it as a side dish alongside roasted vegetables, grilled chicken, or a fresh salad to create a well-rounded meal.
For a lovely presentation, consider garnishing the dish with a sprinkle of fresh thyme or additional grated parmesan cheese just before serving. This will elevate not only the flavor but also the look of the dish. As a bonus, keep in mind that its warm, inviting aroma will have everyone gathering around the table in no time.
Expert Tips: Homemade Garlic Butter Sweet Potato Bake
To ensure your Homemade Garlic Butter Sweet Potato Bake turns out perfectly every time, follow these expert tips. First, make sure your sweet potatoes are uniformly sliced for even cooking. Using the mandoline will give you consistency and speed in preparation.
It’s also crucial to monitor the cooking time; the dish should be tender and creamy, but keep an eye to ensure it doesn’t become overly soft. If you prefer a crispier topping, you can broil the bake for a couple of minutes at the end—just be sure to watch it closely as things can go from golden to burnt in no time!
Lastly, remember to season each layer of sweet potatoes with salt and pepper to really enhance the flavors. Taste the garlic cream sauce and adjust seasonings as needed to suit your palate. This attention to detail will elevate your dish to a gourmet level.
How to Store Homemade Garlic Butter Sweet Potato Bake
If you happen to have leftovers—a rare occurrence indeed—you can easily store your Homemade Garlic Butter Sweet Potato Bake. Allow it to cool completely before transferring it to an airtight container. If you intend to enjoy the leftovers within a few days, simply refrigerate it. It will keep well for about 3 to 4 days.
For longer storage, consider freezing the bake. Just make sure it’s entirely cool, then wrap it tightly with plastic wrap and foil before placing it in the freezer. It should remain good for about 2 to 3 months. When you’re ready for a quick meal, simply thaw it in the refrigerator overnight and reheat it in the oven until heated through.
Variation of Homemade Garlic Butter Sweet Potato Bake
The beauty of this Homemade Garlic Butter Sweet Potato Bake is its versatility. There are several delicious variations you can explore to give it a personal touch. For a bit of a kick, consider adding a pinch of cayenne pepper or red pepper flakes to the garlic butter sauce. This added heat will create a delightful contrast with the sweetness of the potatoes.
If you’re a cheese lover, experiment with different types of cheese. Gruyère or cheddar can be great alternatives to parmesan, adding a unique flavor profile. You might also consider adding layers of thinly sliced onions or even sautéed mushrooms between layers for an earthy twist.
For those who want to include a bit of freshness, try layering in some spinach or kale. This adds not only nutrition but a vibrant color that enhances the dish’s visual appeal. Feel free to play with these ideas, as the essence of this recipe lies in its adaptability to your personal tastes!
