Introduction
This Easy Sweet Potato Egg Casserole is a comforting, hearty dish perfect for breakfast, brunch, or even a light dinner. Packed with savory turkey sausage, tender sweet potatoes, and a cheesy egg mixture, it’s a flavorful and nutritious meal the whole family will enjoy.

Ingredients
- 3 garlic cloves, minced
- 1 lb uncooked turkey sausage
- 5 cups sweet potatoes, cubed (1-inch cubes)
- 1 green bell pepper, diced
- 1/2 large yellow onion, finely diced
- 2 tbsp avocado oil (or olive oil)
- 1/2 cup milk (whole milk recommended)
- 10 large eggs
- 1/2 cup grated mozzarella cheese (Sargento brand recommended)
- 1 tsp salt
- 1 tsp dried thyme
- 1/2 tsp pepper
Instructions
- Step 1: Preheat your oven to 350°F (175°C). Prepare your vegetables by chopping the sweet potatoes, bell pepper, onion, and mincing the garlic. Grease a 9×13-inch casserole dish to prevent sticking.
- Step 2: Heat avocado oil in a Dutch oven or large saucepan over medium heat. Add the diced onion, green bell pepper, and cubed sweet potatoes. Cook for 8-9 minutes, stirring occasionally, until the vegetables start to soften. In the last 1-2 minutes, add the minced garlic and sauté briefly. Remove the vegetables from the pan and spread evenly across the casserole dish.
- Step 3: In the same pan, add the turkey sausage. Cook thoroughly, breaking it into small pieces as it cooks. Once done, combine the cooked sausage with the vegetables in the casserole dish and mix well.
- Step 4: In a mixing bowl, whisk together the eggs, milk, dried thyme, salt, pepper, and grated mozzarella cheese until smooth and well combined.
- Step 5: Pour the egg mixture evenly over the sausage and vegetable mixture in the casserole dish. Stir gently to distribute the egg mixture evenly. Bake in the preheated oven for 40-45 minutes, or until the center feels firm. If the top browns too quickly, cover loosely with foil halfway through baking.
- Step 6: Remove the casserole from the oven and let it cool for about 15 minutes before serving. This resting time helps the flavors settle and makes it easier to slice.
Tips & Variations
- For extra flavor, add a pinch of smoked paprika or cayenne pepper to the egg mixture.
- Swap turkey sausage for chicken or pork sausage, or use a plant-based sausage for a vegetarian version.
- Feel free to add chopped spinach or kale to the vegetable mix for more greens.
- Use cheddar cheese instead of mozzarella for a sharper taste.
Storage

This casserole also freezes well—wrap tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.

FAQs
Can I make this casserole ahead of time?
Yes, you can prepare the casserole a day in advance. Assemble it and keep it covered in the refrigerator, then bake it fresh when ready to serve.
Can I use regular potatoes instead of sweet potatoes?
Yes, regular potatoes can be used, but the flavor and texture will be different. Sweet potatoes provide a natural sweetness that complements the sausage and eggs nicely.

Ingredients
For the Base:
- 3 garlic cloves (minced)
- 1 lb uncooked turkey sausage
- 5 cups cubed sweet potatoes (1-inch cubes)
- 1 green bell pepper (diced)
- 1/2 large yellow onion (finely diced)
- 2 tbsp avocado oil (or olive oil)
For the Egg Mixture:
- 1/2 cup milk (whole milk for richness)
- 10 large eggs
- 1/2 cup grated mozzarella cheese (Sargento brand recommended)
- 1 tsp salt
- 1 tsp dried thyme
- 1/2 tsp pepper
Instructions
- Preheat Oven and Prepare the Baking Dish: Preheat your oven to 350°F (175°C). While it heats, chop all vegetables and grease a 9×13-inch casserole dish to prevent sticking during baking.
- Cook the Vegetables: Heat avocado oil in a Dutch oven or large saucepan. Add the diced onion, green pepper, and sweet potatoes and cook for about 8-9 minutes, stirring occasionally until the vegetables begin to soften. Add minced garlic in the last 1-2 minutes and sauté. Remove from heat and spread evenly in the prepared casserole dish.
- Cook the Sausage: Using the same pan, sauté the turkey sausage until completely cooked, breaking it into small pieces as it cooks. Add the cooked sausage to the vegetables in the casserole dish and stir to combine.
- Prepare the Egg Mixture: In a separate bowl, whisk together the eggs, whole milk, grated mozzarella cheese, salt, dried thyme, and pepper until smooth and well combined.
- Combine and Bake: Pour the egg mixture evenly over the sausage and vegetable mixture in the casserole dish. Gently stir to distribute the eggs throughout. Bake in the preheated oven for 40-45 minutes or until the center is firm and set. If the top browns too quickly, cover loosely with foil to prevent burning.
- Cool and Serve: Remove the casserole from the oven and let it cool for about 15 minutes for easier slicing and to allow flavors to meld before serving.
Notes
- Use whole milk for a richer, creamier casserole; you can substitute with milk alternatives if desired.
- Cover the casserole with foil if the top starts browning too fast during baking.
- Allowing the casserole to rest after baking makes slicing easier and helps flavors develop.
- This recipe can be prepared the night before and refrigerated; bake just before serving.
- For extra flavor, consider adding herbs like parsley or smoked paprika to the egg mixture.
