Sweet Potatoes
Sausage
Yellow Onion
Olive Oil
Garlic
Fresh Rosemary or Thyme

Shredded Cheese (like mozzarella or cheddar)

Sweet Potatoes are the hearty base of the casserole and bring a natural sweetness and creamy texture once roasted. Sausage adds protein and deep, savory flavor that balances the sweetness. Yellow Onion provides a subtle caramelized bite. Olive Oil helps everything roast evenly, while Garlic infuses the whole dish with aromatic warmth. Fresh Rosemary or Thyme enhances the rustic character, and Salt and Pepper tie it all together. Lastly, a sprinkle of Shredded Cheese brings melty goodness right at the end.

How To Make the Sweet Potato and Sausage Casserole

Step 1: Prep and Roast the Sweet Potatoes

Peel and dice the sweet potatoes into bite-sized cubes. Toss them with olive oil, salt, pepper, and a bit of chopped rosemary. Spread on a baking sheet and roast at 400°F for about 25 minutes until fork-tender and lightly caramelized.

Step 2: Cook the Sausage and Onions

While the potatoes are roasting, slice or crumble the sausage and cook it in a skillet over medium heat until browned and cooked through. Add the diced onion and garlic, cooking until the onion is soft and golden.

Step 3: Combine and Assemble

In a large casserole dish, mix the roasted sweet potatoes with the sausage mixture. Stir everything to distribute evenly. Top with shredded cheese.

Step 4: Bake Until Bubbly

Place the casserole in the oven at 375°F for 15–20 minutes, or until the cheese is fully melted and the top is slightly golden.

Step 5: Let It Rest and Serve

Let the casserole rest for 5 minutes before serving. This helps everything settle and makes scooping easier.
