Step-by-Step Instructions

Step 1: Prep the Oven & Ingredients

Preheat your oven to 350°F (175°C). This ensures even baking. Peel the sweet potatoes and cut them into 2-inch cubes so they cook evenly.

Step 2: Mix the Ingredients

In a large mixing bowl, combine:

• Cubed sweet potatoes
• Crushed pineapple (with juice)
• Brown sugar
• Melted butter

Stir well to evenly coat the sweet potatoes with the mixture.

Step 3: Assemble & Bake

Grease a casserole dish (9×9-inch or similar size) to prevent sticking. Pour the sweet potato-pineapple mixture into the dish and spread it evenly. Bake uncovered for 45-50 minutes until the sweet potatoes are fork-tender.

Step 4: Serve & Enjoy!

Remove from the oven and let it cool for 5 minutes. Serve warm as a delicious side dish.

Recipe Variations
