Step‑by‑Step Instructions for Sweet Potato and Sausage Casserole
Step 1: Preheat Oven
Begin by preheating your oven to 375°F (190°C). This ensures a hot environment for a beautifully cooked Sweet Potato and Sausage Casserole. Preparing your oven first helps streamline the cooking process and allows the casserole to bake evenly when it’s ready to go in.
Step 2: Brown the Sausage
In a large skillet over medium heat, add the Italian sausage, breaking it up as it cooks. Brown the sausage for about 5–7 minutes until fully cooked, stirring occasionally until it reaches a rich, golden color and no longer pink. This step infuses the dish with a savory flavor base that’s simply irresistible.
Step 3: Sauté Onion and Garlic
Next, add the chopped onion and minced garlic to the skillet with the sausage. Cook them together for 3–4 minutes until the onion is translucent and softened, stirring frequently to prevent burning. The aroma from the sautéing garlic will enhance your kitchen’s atmosphere and pave the way for the comforting layers ahead.
Step 4: Add Sweet Potatoes and Seasoning
Now, stir in the diced sweet potatoes, along with smoked paprika, salt, and pepper. Cook this mixture for an additional 5 minutes, stirring occasionally to combine the flavors. The sweet potatoes should start to soften, filling your kitchen with a lovely, seasonal scent that previews the deliciousness to come.
Step 5: Simmer with Broth
Pour in the chicken broth and bring the mixture to a gentle simmer. Cover the skillet and let it cook for about 10 minutes, until the sweet potatoes are just tender. This step allows the flavors to meld beautifully while the sweet potatoes absorb the savory broth, creating a harmonious base for your casserole.
Step 6: Transfer to Baking Dish
Carefully transfer the sausage and sweet potato mixture to a greased 9×13-inch baking dish. Spread the filling evenly across the dish, showcasing the vibrant colors. This is where your Sweet Potato and Sausage Casserole really comes together for a cozy family meal.
Step 7: Top with Cheese
Sprinkle a generous layer of shredded cheddar cheese over the top of the casserole. This cheesy crown will melt and form a lovely golden crust as it bakes, elevating the dish’s comforting appeal. Ensure even coverage for that gooey, melty goodness we all love.
Step 8: Bake Covered and Uncovered
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 25 minutes, then remove the foil and bake for another 15 minutes. Watch for the cheese to bubble and turn golden, creating that mouthwatering crust that makes this Sweet Potato and Sausage Casserole so inviting.
Step 9: Let Rest Before Serving
Finally, pull the casserole from the oven and let it rest for about 10 minutes before serving. This resting period helps the flavors meld beautifully and makes cutting into the casserole easier. Serve warm and enjoy the cozy, hearty flavors that epitomize fall!

Sweet Potato and Sausage Casserole Recipe FAQs
What type of sweet potatoes should I use?
Absolutely! When selecting sweet potatoes, look for firm, smooth ones without dark spots or soft spots. The smaller, younger tubers tend to be sweeter and cook more quickly. If you’re looking for alternatives, butternut squash or regular potatoes can work beautifully; just remember to adjust the cooking time as needed.
How should I store leftovers from the casserole?
Ensure your delicious Sweet Potato and Sausage Casserole cools completely before transferring it to an airtight container. You can store it in the fridge for up to 3 days. If you’re like me and love meal prepping, you can also freeze portions in airtight containers for up to 3 months for easy future meals.
Can I freeze the casserole?
Very much! To freeze, allow the casserole to cool down and portion it into airtight containers or sturdy freezer bags. Be sure to label each with the date, so you know when to enjoy it. When you’re ready to eat, thaw it overnight in the fridge, then reheat in the oven at 350°F (175°C) until warmed through, about 20 minutes.
What if my casserole seems too watery?
No worries! If you find that your casserole looks watery once you remove the foil during baking, cook it uncovered for an additional 5 to 10 minutes. This will help evaporate excess moisture and allow the cheese to crisp up beautifully, giving you that perfect texture.
Are there any dietary considerations I should keep in mind?
Absolutely! For those with allergies, be aware that this casserole contains dairy from the cheese and can be made gluten-free by choosing suitable sausage and broth. If you’re looking for a vegetarian or vegan option, feel free to substitute the sausage with lentils or plant-based sausage and use vegetable broth; just ensure your spices maintain their robust flavor.
Can I add other vegetables to the casserole?
The more the merrier! You can definitely get creative by adding seasonal veggies like bell peppers, kale, or even zucchini. I recommend sautéing any additional vegetables briefly before mixing them in so they’ll cook nicely and keep their texture in the casserole.
