Prep Time 15 minutes
Cook Time 45 minutes
Total Time 1 hour
Servings: 8 servings
Course: Side Dish
Cuisine: American
Calories: 465

Ingredients
  

  • 3 lbs sweet potatoes sliced
  • 4 Tbsp unsalted butter
  • 4 garlic cloves minced
  • 1 Tbsp all-purpose flour
  • 1/3 cup parmesan cheese
  • 1 cup whole milk
  • 1 cup heavy whipping cream
  • 1 tsp sea salt
  • ¼ tsp ground black pepper
  • 2 cups Colby Jack cheese shredded

Equipment

  • mandoline slicer
  • medium saucepan
  • whisk
  • 9×13-inch casserole dish
  • aluminum foil

Method
 

  1. First, peel and finely slice your sweet potatoes into very thin rounds. Aim for about 1/8 inch thickness for even cooking.
  2. In a medium saucepan, melt the unsalted butter over medium heat. Add the minced garlic and sauté until it becomes fragrant, about 1 minute. Whisk in the all-purpose flour until it forms a smooth paste, cooking for another minute to remove any raw flour taste.
  3. Gradually whisk in the Parmesan cheese, whole milk, and heavy whipping cream into the flour mixture. Add the sea salt and ground black pepper. Bring the mixture to a soft boil, stirring constantly, then immediately remove it from the heat. Allow the cream sauce to cool for about 10-15 minutes. Once cooled, stir in the shredded Colby Jack cheese until well combined. This is key for our creamy scalloped sweet potatoes.
  4. Lightly grease a 9×13-inch casserole dish. Arrange the thinly sliced sweet potatoes in neat, overlapping rows in the dish. Pour the cheese mixture evenly over the sweet potato slices, ensuring all are covered.
  5. Cover the casserole dish tightly with aluminum foil. Bake in a preheated oven at 400°F (200°C) for 30-35 minutes. After this time, remove the foil and bake for an additional 8-10 minutes, or until the top is golden brown and bubbly. A knife should slide easily through the tender scalloped sweet potatoes. Serve warm and enjoy!

Understanding Sweet Potatoes: More Than Just a Side Dish

The term “scalloped” refers to dishes where ingredients are baked in a sauce, often with a gratin-like crust. This usually involves thinly sliced items, creating beautiful, even layers. Our scalloped sweet potatoes are a beautiful example, showcasing creamy layers rather than a crumbly topping. Unlike traditional sweet potato casserole, this version focuses on tender, saucy slices, offering a sophisticated balance of savory depth and subtle sweetness. It challenges the idea that all sweet potato dishes must lean heavily on sugar.

Crafting Your Perfect Sweet Potatoes: Step-by-Step

  1. Prepare the Sweet Potatoes: First, peel and finely slice your sweet potatoes into very thin rounds. Aim for about 1/8 inch thickness for even cooking.
  2. Start the Roux: In a medium saucepan, melt the unsalted butter over medium heat. Add the minced garlic and sauté until it becomes fragrant, about 1 minute. Whisk in the all-purpose flour until it forms a smooth paste, cooking for another minute to remove any raw flour taste.
  3. Make the Cream Sauce: Gradually whisk in the Parmesan cheese, whole milk, and heavy whipping cream into the flour mixture. Add the sea salt and ground black pepper. Bring the mixture to a soft boil, stirring constantly, then immediately remove it from the heat. Allow the cream sauce to cool for about 10-15 minutes. Once cooled, stir in the shredded Colby Jack cheese until well combined. This is key for our creamy scalloped sweet potatoes.
  4. Assemble the Dish: Lightly grease a 9×13-inch casserole dish. Arrange the thinly sliced sweet potatoes in neat, overlapping rows in the dish. Pour the cheese mixture evenly over the sweet potato slices, ensuring all are covered.
  5. Bake to Perfection: Cover the casserole dish tightly with aluminum foil. Bake in a preheated oven at 400°F (200°C) for 30-35 minutes. After this time, remove the foil and bake for an additional 8-10 minutes, or until the top is golden brown and bubbly. A knife should slide easily through the tender scalloped sweet potatoes.

Expert Tips for Flawless Scalloped Sweet Potatoes

Achieving perfectly creamy and tender scalloped sweet potatoes is easier with a few insider tips.

  • Slicing Sweet Potatoes: Uniform, thin slices (around 1/8 inch) are crucial for even cooking. A mandoline slicer makes this task quick and consistent. If using a knife, take your time for similar results.
  • The Cream Sauce: Allowing the cream sauce to cool slightly before adding the shredded cheese prevents clumping. This ensures a beautifully smooth, even texture throughout your dish.
  • Doneness Test: Insert a sharp knife into the center. It should slide through the potatoes easily when fully cooked. Look for bubbly sauce and golden-brown edges.
  • Baking Dish Choice: A 9×13-inch casserole dish is ideal. Deeper dishes may require slightly longer baking times to ensure the center cooks through.

Prep Ahead & Store: Your Sweet Potatoes, Made Easy

You can easily prepare these scalloped sweet potatoes in advance. Assemble the entire dish, cover it tightly, and refrigerate unbaked for up to 2 days. Add 10-15 minutes to the baking time if starting from cold. Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven at 300°F or microwave small portions until warmed through. Freezing is not recommended as the sauce can separate.

For a simpler meal, they complement a pan-seared steak or even a hearty lentil loaf. Their balanced flavor makes them a wonderful companion to nearly any main course.

The Wholesome Goodness of Scalloped Sweet Potatoes

Sweet potatoes are truly a nutritional powerhouse, making our scalloped sweet potatoes a healthy and delicious choice. They are packed with Vitamin A, crucial for vision and immune function, and a good source of Vitamin C for skin health and antioxidants. Compared to traditional white potatoes, sweet potatoes offer a higher amount of beta-carotene, giving them their vibrant orange hue. They also provide dietary fiber, contributing to digestive health.

Frequently Asked Questions

  • Why is my sauce watery/not thickening? This often happens if there wasn’t enough flour in the roux or the sauce didn’t simmer long enough. Ensure your roux cooks for a full minute, and the sauce comes to a soft boil.
  • My potatoes are still hard after baking, what happened? Slices that are too thick or insufficient baking time are common culprits. Make sure your sweet potato slices are thin and uniform for even cooking.
  • Can I use other types of potatoes? While you can use other potatoes like Yukon Golds, sweet potatoes offer a unique flavor and nutritional profile perfect for this creamy dish.
  • How do I choose the best sweet potatoes for this recipe? Look for firm, blemish-free sweet potatoes. Varieties like Garnet or Jewel are excellent choices for their texture and vibrant color in scalloped sweet potatoes.
  • Are these Scalloped Sweet Potatoes overly sweet? No, this recipe balances the sweet potato’s natural sugars with savory elements like garlic and Parmesan, resulting in a perfectly harmonious, not cloyingly sweet, flavor.
