Sweet Potato Egg Casserole Ingredients
• Here’s everything you need!
For the Base
- Sweet Potatoes – A staple for natural sweetness and texture; choose orange-fleshed varieties for the best results.
- Onion – Adds savory depth; shallots work well, too, if you prefer a milder flavor.
- Green Pepper – Offers a slight crunch; feel free to substitute with your favorite bell pepper.
- Garlic – Enhances flavor and aroma; fresh garlic is preferred, but garlic powder can suffice in a pinch.
- Turkey Sausage – Provides heartiness and protein; swap for vegetarian sausage or omit for a meatless option.
For the Custard

Step‑by‑Step Instructions for Sweet Potato Egg Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This will ensure that your Sweet Potato Egg Casserole bakes evenly, creating a beautifully fluffy texture. While your oven warms up, gather all your ingredients and equipment, including a large mixing bowl, a sauté pan, and a greased 9×13-inch casserole dish.
Step 2: Prepare the Vegetables
Chop the sweet potatoes, onion, green pepper, and garlic into uniform pieces. Aim for ½-inch cubes for the sweet potatoes to ensure even cooking. After chopping, your veggies should look vibrant and fresh. Set the prepared vegetables aside as you get ready to sauté.
Step 3: Sauté the Vegetables
In your sauté pan, add a drizzle of avocado oil and heat over medium heat. Once hot, add the sweet potatoes, onion, green pepper, and garlic, sautéing for about 8-9 minutes. Stir frequently until the vegetables soften and become fragrant, with the sweet potatoes taking on a tender bite and a slight golden hue.
Step 4: Layer the Casserole
Carefully remove the sautéed vegetables from the pan and layer them evenly in your greased casserole dish. This creates a colorful base for your Sweet Potato Egg Casserole, ensuring every bite is packed with flavor. The vegetables should be spread out to form an even layer that fills the bottom of the dish.
Step 5: Cook the Sausage
In the same sauté pan, add your turkey sausage and cook over medium heat until it is fully browned, about 5-7 minutes. Break it apart with a spatula as it cooks. The sausage should be well-cooked with no pink remaining. Once done, drain any excess fat and stir it into the vegetable layer in the casserole dish.
Step 6: Whisk the Egg Mixture
In a large mixing bowl, whisk together the eggs, milk, thyme, salt, pepper, and shredded cheese until the mixture is smooth and well combined. You want to achieve a homogenous blend, where the yellow of the eggs is uniform with the milk and seasoning. This custard will bring delicious creaminess to your Sweet Potato Egg Casserole.
Step 7: Combine Layers
Pour the egg mixture over the layered vegetables and sausage in the casserole dish. Use a spatula to gently stir and combine the layers, ensuring that the egg mixture seeps into every nook and cranny. The top should look inviting and colorful, ready to be baked to perfection.
Step 8: Bake the Casserole
Place the casserole in your preheated oven and bake for 40-45 minutes. Keep an eye on it, covering with foil if the top begins to brown too quickly. The casserole is ready when the edges are set, and the center has a slight jiggle—just perfect for a comforting Sweet Potato Egg Casserole.
Step 9: Cool and Serve
After baking, remove the casserole from the oven and let it cool for 5-10 minutes before serving. This resting time helps the casserole set, making it easier to slice. The warm, inviting aroma will fill your kitchen, beckoning your family to the table for a hearty breakfast!

How to Store and Freeze Sweet Potato Egg Casserole
Fridge: Store leftovers in an airtight container for up to 4 days. This keeps the flavors fresh and ready for quick meals.
Freezer: Cut portions can be frozen for up to 3 months. Wrap them tightly in plastic wrap and foil before placing in a freezer-safe bag.
Reheating: For best results, reheat in the oven at 350°F (175°C) until warmed through. The microwave works too—just cover to keep moisture in!
Make-Ahead: Assemble your Sweet Potato Egg Casserole the night before, refrigerate, and bake in the morning for a hassle-free breakfast experience.
Expert Tips for Sweet Potato Egg Casserole
Uniform Cuts: Ensure sweet potatoes are cut into ½-inch cubes for even cooking; uneven sizes can lead to some pieces being under or overcooked.
Don’t Overcrowd: Avoid overcrowding the pan when sautéing vegetables to achieve proper browning instead of steaming—this affects the casserole’s overall texture.
Drain Excess Liquid: Be sure to drain any excess liquid from your cooked sausage and vegetables to prevent a watery Sweet Potato Egg Casserole.
Let It Rest: Allow the casserole to cool for 5-10 minutes after baking; this resting time helps it set for cleaner slices.
Adapt with Ease: Feel free to mix in your favorite veggies or swap proteins for variety; this recipe is designed to be flexible and fun!
