Ingredients for the Perfect Sweet Potato Casserole Recipe

Selecting and Preparing Sweet Potato Casserole Recipe
The foundation of any outstanding sweet potato casserole begins with choosing the right sweet potatoes. Look for medium to large specimens with smooth, unblemished skin and a deep orange color. For best results, select potatoes that are similar in size to ensure even cooking time.
When preparing your sweet potatoes, you have two main cooking options:
- Baking: Wrap potatoes in foil and bake at 400°F for about an hour
- Boiling: Cut into large chunks and boil for 20-25 minutes
Both methods work well, though baking tends to concentrate the flavors and reduce moisture content. Whatever method you choose, ensure the potatoes are fork-tender before mashing. This step is crucial for achieving that perfect, creamy texture that makes this dish so irresistible.

- Butter (½ cup, melted)

- Eggs (2 large)
- Provide structure
- Create a soufflé-like texture
- Help bind ingredients together
- Milk or cream (½ cup)

Step-by-Step Sweet Potato Casserole Recipe Instructions
Preparation and Base Assembly
Let’s walk through creating the perfect sweet potato casserole, starting with the essential prep work. First, preheat your oven to 375°F and grease a 9×13 inch baking dish. Next, begin with your cooked and cooled sweet potatoes – you’ll need about 4 pounds to serve 10-12 people.
