• 1 cup fresh spinach, chopped: A mild, earthy green that blends beautifully with eggs.
• ½ cup diced bell peppers: Brings crunch and a pop of colorful sweetness.

• ½ cup shredded cheddar or mozzarella cheese: Melts to a golden, gooey topping with a lovely stretch.

How to Make Protein-Packed Sweet Potato Egg Casserole

Step 1: Preheat and Prepare the Sweet Potatoes

Start by heating your oven to 375°F (190°C) and giving a 9×13-inch baking dish a little grease so nothing sticks. Spread your diced sweet potatoes evenly in the dish and roast them for about 15 to 20 minutes until they are just tender. This roasting step enhances their natural sweetness and ensures they won’t be too firm inside the casserole.

Step 2: Whisk Together the Egg Mixture

While the sweet potatoes are roasting, grab a large bowl and whisk your eggs with milk, garlic powder, paprika, salt, and black pepper until well combined. Then fold in the chopped spinach, diced bell peppers, onions, and if you’re using them, the cooked chicken, turkey, or sausage. This mixture will create the flavorful, protein-rich base of your casserole.

Step 3: Combine and Assemble

Once the sweet potatoes are roasted, add them gently into your egg and vegetable mixture, stirring carefully so you maintain some texture without breaking them down completely. Pour everything back into your prepared baking dish and spread evenly. Finally, sprinkle the shredded cheese generously over the top, setting yourself up for that irresistible golden melt.

Step 4: Bake to Perfection

Place your dish in the oven and bake for 25 to 30 minutes. You’ll want the eggs fully set with no jiggle, and the cheese on top bubbling and turning a lovely golden brown. Once out of the oven, let it rest for about five minutes—this helps it firm up slightly and makes slicing a breeze.

Side Dishes

This casserole shines as a stand-alone dish but pairing it with a crisp green salad or fresh fruit salad can balance its richness wonderfully. For a cozy brunch, warm up some crusty bread or whole-grain toast alongside to soak up every last bite.

Make Ahead and Storage

Storing Leftovers

Leftover Protein-Packed Sweet Potato Egg Casserole keeps beautifully in an airtight container in the refrigerator for up to four days. Each time you reheat a slice, the flavors only get better, making it a fantastic option for meal prep or busy mornings.

Freezing

If you want to stash some away, this casserole freezes well. Wrap individual portions tightly or place the whole dish (once cooled) in a freezer-safe container. It can stay fresh for up to three months, ready to thaw and bake again when you need a protein-packed meal in a flash.

Reheating

For reheating, use the microwave for quick and easy bites or gently warm slices in the oven at 350°F (175°C) wrapped in foil to keep moisture locked in. Reheated casserole still retains that wonderful creamy texture and robust flavor that originally made you fall in love.

FAQs

Can I make this casserole vegan or dairy-free?

Absolutely! Simply swap the eggs for a flaxseed or chickpea flour mixture and use plant-based milk and dairy-free cheese. The casserole will still be flavorful and packed with protein, especially if you add plant protein alternatives like tofu or tempeh.

What protein options work best in the Protein-Packed Sweet Potato Egg Casserole?

Cooked chicken, turkey, and sausage are classic choices that enhance the dish’s hearty feel. You can also try crumbled bacon or even cooked lentils for a vegetarian twist. Each option adds its own character without overwhelming the cozy base.

Can I prepare this casserole the night before?

Yes, preparing everything the night before and assembling just before baking saves time in the morning. You can keep the egg mixture and roasted sweet potatoes covered separately in the fridge, then combine and bake when ready.

Is it possible to use regular potatoes instead of sweet potatoes?

While you can substitute regular potatoes, sweet potatoes provide a unique natural sweetness and moisture that balance the savory elements perfectly. If you do use regular potatoes, parboil or roast them well beforehand to ensure they cook thoroughly during baking.

How many servings does this recipe make?

This recipe serves approximately six people, making it ideal for family breakfasts or small gatherings. Leftovers store well, too, so you might find yourself enjoying it for several days after making it.
