Preparation Tips

For a casserole that’s bursting with flavor, make sure to roast the sweet potatoes until they’re just tender—they’ll continue cooking in the oven. Browning the sausage well adds depth and richness, so don’t rush this step. When combining ingredients, ensure they’re well mixed so every bite includes a balance of meat, veggies, and sweet potatoes. Fresh herbs like parsley or thyme can brighten the overall flavor. Lastly, use freshly shredded cheese if possible—it melts more smoothly than pre-packaged shreds.

Ingredients for this Sweet Potato and Sausage Casserole

• 1 lb ground sausage (pork, turkey, or chicken)
• 2 large sweet potatoes, peeled and diced into 1/2-inch cubes
• 1 red bell pepper, chopped
• 1 green bell pepper, chopped
• 1 cup frozen peas (thawed)
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 1 1/2 cups shredded mozzarella or cheddar cheese
• 2 tbsp olive oil
• 1 tsp smoked paprika
• 1/2 tsp dried thyme
• Salt and black pepper to taste
• Fresh parsley for garnish (optional)

---

Step 1: Roast the Sweet Potatoes

Preheat your oven to 400°F (200°C). Toss diced sweet potatoes with 1 tbsp olive oil, smoked paprika, salt, and pepper. Spread them on a baking sheet in a single layer. Roast for 20-25 minutes until tender and slightly caramelized. Remove from oven and set aside.

---

Step 2: Cook the Sausage

In a large skillet over medium heat, add 1 tbsp olive oil. Cook the ground sausage, breaking it apart with a wooden spoon, until browned and fully cooked through (about 8-10 minutes). Remove sausage from skillet and set aside, leaving some of the rendered fat in the pan.

---

Step 3: Sauté the Vegetables

In the same skillet with leftover sausage fat, add chopped onion, bell peppers, and garlic. Sauté for about 5-7 minutes until softened and slightly golden. Season with dried thyme and a pinch of salt. Stir in the thawed peas, cook for another 1-2 minutes, then remove from heat.

---

Step 4: Combine the Ingredients

In a large mixing bowl, combine the roasted sweet potatoes, cooked sausage, and sautéed vegetables. Mix thoroughly so all components are evenly distributed. Taste and adjust seasoning with more salt and pepper if needed.

---

Step 5: Assemble the Casserole

Transfer the mixture into a greased 9×13-inch baking dish. Spread it out evenly and top with shredded cheese.

---

Step 6: Bake the Casserole

Lower the oven temperature to 375°F (190°C). Bake the assembled casserole uncovered for 15-20 minutes, or until the cheese is melted and bubbly. For a golden top, broil for an additional 2-3 minutes.

---

Step 7: Garnish and Serve

Let the casserole rest for 5 minutes before serving. Sprinkle freshly chopped parsley on top for color and freshness. Serve warm as a standalone dish or alongside a green salad.

Notes

This casserole is highly versatile. You can substitute the sausage with plant-based alternatives for a vegetarian version or use spicy sausage if you prefer a kick. Roasting the sweet potatoes separately before combining them with other ingredients is key—it enhances their flavor and prevents sogginess. If you’re short on time, you can prep the veggies and cook the sausage a day in advance.

Watch Out for These Mistakes While Cooking

• Skipping the roasting step for sweet potatoes: This leads to a mushy texture and less flavor.
• Overcooking the sausage: It can become dry and crumbly, affecting the overall mouthfeel.
• Under-seasoning: Make sure to season each component well to ensure a flavorful casserole.
• Overloading with cheese: While tempting, too much cheese can make the dish greasy.
• Using watery vegetables without sautéing: Veggies like zucchini or mushrooms should be cooked down first to avoid excess moisture.
