Golden Sweet Potato Egg Casserole
The morning I made this casserole, the kitchen filled with the scent of roasted sweet potatoes and sizzling turkey sausage long before the sun had fully risen. It was one of those quiet mornings when the house still felt sleepy, and I wanted to make something warm and nourishing to start the day on the right note.
I had some leftover sweet potatoes from the night before, a few eggs, and a green bell pepper just begging to be used. As I chopped the vegetables, the rhythm of cooking felt calm and steady the kind that wakes you up better than coffee.
When the casserole finally came out of the oven, its golden top shimmered with melted cheese, and the aroma had everyone wandering into the kitchen before I could even slice it. The first bite brought everything together: soft, naturally sweet potatoes, savory turkey sausage, and the subtle herby note of thyme.
This isn’t a fancy brunch dish that requires hours of prep or expensive ingredients it’s a wholesome, protein packed meal that fits perfectly into a busy morning or lazy weekend breakfast. Each bite feels balanced, satisfying, and comforting without being heavy.

Cooking Instructions
Step 1: Preheat Oven and Prepare the Baking Dish
Preheat your oven to 350°F (175°C). Grease your 9×13 inch baking dish with avocado oil or cooking spray.
Step 2: Cook the Vegetables
Cook for 8–9 minutes, stirring occasionally, until the vegetables begin to soften.
In the last 1–2 minutes, add minced garlic and sauté until fragrant. Transfer the mixture to the baking dish and spread evenly across the bottom.
Step 3: Cook the Sausage
Using the same pan, cook the turkey sausage over medium heat. Break it into small pieces as it browns.
Step 4: Prepare the Egg Mixture
In a large bowl, whisk together eggs, milk, dried thyme, salt, pepper, and mozzarella cheese. Whisk until smooth and well combined.
Step 5: Combine and Bake
Pour the egg mixture over the vegetables and sausage. Stir gently to distribute evenly. Bake in the preheated oven for 40–45 minutes, or until the center feels firm and set.
Step 6: Cool and Serve
Remove the casserole from the oven and let it rest for 15 minutes before slicing. This helps the flavors meld and makes cutting easier. Serve warm.
