Preparation Phase & Tools to Use

Creating this casserole doesn’t require a complex toolkit, but having the right equipment makes the process smoother and the result even better:

• Large Skillet: Crucial for browning the sausage and sautéing any veggies. A good sear builds deep flavor.
• Sharp Chef’s Knife: You’ll want clean, even cuts on your sweet potatoes so they cook uniformly.
• Cutting Board: Opt for a large one to safely handle all your prep work.
• Mixing Bowl: For tossing together your ingredients before assembling the casserole.
• 9×13″ Baking Dish: This size works well for evenly cooking the casserole and getting those golden edges.
• Aluminum Foil: Helpful for covering the dish if the top browns too quickly during baking.

Each of these tools contributes to a well-executed dish that’s as pleasing to look at as it is to eat.

How To Make the Sweet Potato and Sausage Casserole

Step 1: Roast the Sweet Potatoes

Preheat your oven to 400°F. Toss cubed sweet potatoes in olive oil, salt, and pepper. Spread them on a baking sheet and roast for 25-30 minutes until tender and lightly caramelized.

Step 2: Cook the Sausage

While the potatoes roast, heat a large skillet over medium heat. Cook the ground sausage until browned and crumbled. Drain excess grease if needed.

Step 3: Combine Ingredients

In a mixing bowl, combine the roasted sweet potatoes, cooked sausage, diced bell peppers, and half the green onions. Toss gently to mix.

Step 4: Assemble the Casserole

Transfer the mixture into a greased 9×13″ baking dish. Sprinkle shredded cheese evenly over the top.

Step 5: Bake

Lower the oven temperature to 375°F. Bake uncovered for 20 minutes, or until cheese is melted and bubbly.

Step 6: Garnish and Serve

Remove from the oven and top with the remaining green onions for a fresh finish. Let rest for 5 minutes before serving.
