Step-by-Step Instructions
Preheat oven: Start by preheating your oven to 375°F (190°C). Grease a 9×13 inch baking dish with olive oil or cooking spray to prevent sticking.
Cook sweet potatoes: In a pan, cook the diced sweet potatoes over medium heat for about 10-15 minutes until they’re tender. Stir occasionally to avoid sticking.
Make the egg mixture: In a large bowl, whisk together the eggs, milk, salt, black pepper, garlic powder, and thyme if you’re using it.
Combine ingredients: Add the tender sweet potatoes, shredded cheese, and diced onion to the egg mixture. Stir gently until everything is well combined.
Pour and spread: Transfer the mixture to the greased baking dish and spread it evenly.
Bake: Place the casserole in the oven and bake for 25-30 minutes, or until the center is set and the top is golden brown.
Cool and serve: Once baked, allow the casserole to cool for a few minutes before slicing into portions. Enjoy your cozy breakfast!
Best Ways to Enjoy It
This casserole is versatile in how you can enjoy it. Serve it warm right out of the oven and consider pairing it with:
- A fresh side salad for added crunch and nutrition.
- Toasted slices of whole grain bread to soak up the flavors.
- A dollop of Greek yogurt or sour cream for a creamy touch.
- Fresh herbs or avocado slices for a twist.
Storage and Reheating Tips
To keep your leftovers fresh, store any uneaten casserole in an airtight container in the fridge. It will last for about 3-4 days. When you’re ready to enjoy it again, simply reheat individual portions in the microwave or warm it up in the oven at 350°F (175°C) until heated through.
Helpful Cooking Tips
- Cook time is key: Ensure that the sweet potatoes are adequately tender before mixing them with the eggs. This prevents any crunchiness in the final dish.
- Eggs make a difference: Use room temperature eggs for a fluffier texture.
- Greasing matters: Don’t skimp on greasing the baking dish; it helps ensure easy serving.
