The first chill of autumn always seems to invite the smell of something baking in my kitchen. A few weeks ago, I woke early to the soft sound of rain on the window. My husband was still asleep, the house was quiet, and I felt that familiar urge to cook something warm and comforting.
I wandered into the kitchen, opened the fridge, and saw a basket of sweet potatoes from our neighbor’s garden sitting on the counter. They were a deep orange, freshly dug, and still carried a hint of earthiness. That’s when the idea for a hearty Sweet Potato Egg Casserole came to mind—simple, wholesome, and full of the flavors we love.
By the time my husband came down, the oven was working its magic. The smell of roasted sweet potatoes, thyme, and turkey sausage filled every corner of the house. I brewed some coffee, set the table, and we sat by the window watching the rain fall while sharing a meal that felt like a warm hug.

Key Ingredients
- 2 tablespoons avocado oil
- ½ large yellow onion, chopped
- 1 green bell pepper, chopped
- 5 cups cubed sweet potatoes
- 3 garlic cloves, minced
- 1 pound turkey sausage
- 10 eggs
- ½ cup milk (plant-based milk works too)
- 1 teaspoon dried thyme
- 1 teaspoon salt
- ½ teaspoon pepper
- ½ cup grated mozzarella cheese
Tools Needed
- 9×13-inch casserole dish
- Dutch oven or large skillet
- Mixing bowls
- Whisk
- Wooden spoon or spatula
Cooking Instructions
Step 1: Preheat Oven and Prepare the Baking Dish
Preheat your oven to 350°F (175°C). Grease a 9×13-inch casserole dish with a bit of avocado oil or butter. While the oven heats, chop your onion, green bell pepper, and sweet potatoes into bite-sized cubes so they cook evenly.
Step 2: Cook the Vegetables
In a Dutch oven or large skillet, heat the avocado oil over medium heat. Add the onion, bell pepper, and sweet potatoes. Cook for about 8–9 minutes, stirring occasionally, until the vegetables start to soften and the sweet potatoes get a light golden edge. In the last minute of cooking, add minced garlic and sauté until fragrant. Transfer everything into the prepared casserole dish, spreading it evenly across the bottom.
Step 3: Cook the Sausage
Using the same pan, add the turkey sausage and cook over medium heat. Break it up with your spoon as it cooks until it’s browned and no longer pink. Drain any excess grease, then scatter the cooked sausage over the vegetables in the casserole dish. Stir gently to combine.
Step 4: Prepare the Egg Mixture
In a mixing bowl, whisk together the eggs, milk, dried thyme, salt, pepper, and shredded mozzarella. Whisk until smooth and fully combined. The thyme adds a gentle earthiness that pairs beautifully with the sweetness of the potatoes.
Step 5: Combine and Bake
Pour the egg mixture evenly over the vegetables and sausage. Use a spoon to gently stir, making sure everything is evenly coated. Bake in the preheated oven for 40–45 minutes, or until the center feels firm to the touch and the top turns golden. If the top browns too quickly, tent it lightly with foil halfway through baking.
Step 6: Cool and Serve
Remove from the oven and let the casserole rest for about 15 minutes before slicing. This helps the layers set and makes serving easier. Slice into squares and enjoy warm.

Mistakes to Avoid & Solutions
Undercooked Sweet Potatoes: Make sure they’re softened before baking. If they’re too firm, they’ll stay crunchy in the final dish.
Watery Casserole: Don’t add extra milk or overmix the eggs—stick to the measurements. If your veggies release a lot of liquid, drain them before combining.
Dry Texture: Overbaking can cause this. Check for doneness around 40 minutes; the center should be just set, not rubbery.

FAQs
1. Can I make this casserole ahead of time?
Yes. Assemble everything the night before, cover tightly, and refrigerate. Bake it fresh in the morning.
2. Can I use regular sausage instead of turkey?
Absolutely. Pork or chicken sausage works fine—just drain any excess fat.
3. Can I skip the cheese?
Yes, but the cheese adds creaminess and helps bind the casserole. Try dairy-free cheese if preferred.
4. Can I add spinach or kale?
Definitely. Stir in a handful of chopped greens when you add the sausage for extra color and nutrition.
5. What’s the best way to tell when it’s done?
The center should be set and slightly puffed. Insert a knife—if it comes out clean, it’s ready.
Tips & Tricks
Cut the sweet potatoes into small, even cubes for quicker, uniform cooking.
Lightly toast your spices before adding them to bring out deeper flavors.
Sprinkle a little extra mozzarella on top before baking for a golden crust.
Letting it cool slightly before serving helps the flavors meld beautifully.
For added crunch, top with crushed almonds or roasted seeds after baking.
Recipe Variations
Veggie Lover’s Version: Replace the sausage with mushrooms, spinach, and zucchini. Add ¼ teaspoon smoked paprika for depth.
Spicy Southwest Casserole: Use chorizo instead of turkey sausage, and add ½ teaspoon chili powder and a sprinkle of cheddar instead of mozzarella.
Mediterranean Twist: Substitute mozzarella with feta cheese and toss in diced tomatoes, olives, and spinach.
Dairy-Free Option: Use plant-based milk and vegan cheese. The texture stays light and fluffy.
Mini Muffin Casseroles: Pour the mixture into greased muffin tins and bake for 25 minutes—perfect for grab-and-go breakfasts.
