How To Make Protein-Packed Sweet Potato Egg Casserole

Follow these easy steps to prepare your fantastic Protein-Packed Sweet Potato Egg Casserole.

  1. Prep Vegetables: Start by dicing your sweet potatoes into small, even cubes. Also, dice the red bell pepper and chop the onion. This ensures everything cooks evenly.
  2. Sauté Sweet Potatoes: Heat a drizzle of oil in a large skillet over medium-high heat. Add the cubed sweet potatoes, cover with a lid, and cook for about 8 minutes. Stir them occasionally until they are tender-crisp.
  3. Add Other Veggies: Incorporate the diced onion and red bell pepper into the skillet with the sweet potatoes. Season with a pinch of salt and black pepper. Cook for another 3 minutes until all the vegetables are tender.
  4. Transfer Vegetables: Carefully spoon the cooked vegetable mixture from the skillet into your 9×13-inch casserole dish. Spread them out evenly across the bottom.
  5. Brown Sausage: Add the ground sausage to the same skillet (no need to clean it). Cook over medium-high heat for about 5 minutes, crumbling the sausage with a spoon as it cooks. Ensure it is fully browned.
  6. Drain Fat (Optional): If your sausage has rendered a lot of fat, you can drain the excess from the skillet for a lighter casserole. Use a spoon or tilt the pan.
  7. Combine Sausage: Transfer the browned sausage directly into the casserole dish with the vegetables. Distribute it evenly over the sweet potato and pepper mixture.
  8. Prepare Egg Mixture: In a medium bowl, whisk together the 8 eggs, 1/3 cup almond milk, 1 teaspoon thyme, 1 teaspoon salt, and 1/2 teaspoon black pepper until well combined and slightly frothy.
  9. Pour & Mix: Pour the whisked egg mixture evenly over the sausage and vegetable layers in the casserole dish. Gently stir the ingredients in the dish to ensure the egg mixture coats everything thoroughly.
  10. Bake Covered: Cover the casserole dish tightly with aluminum foil. Place it in a preheated 375°F (190°C) oven and bake for 20 minutes.
  11. Bake Uncovered: Remove the aluminum foil from the casserole dish. Continue baking for an additional 15 minutes, or until the top of the potatoes begins to brown and the eggs are set.
  12. Rest & Serve: Take the casserole out of the oven and let it rest for 5 minutes before slicing. Garnish with fresh green onions if desired, then serve this delicious Protein-Packed Sweet Potato Egg Casserole warm.

Pro Tips for the Best Results

Achieve perfect results every time with these helpful hints for your Protein-Packed Sweet Potato Egg Casserole.

  • Even Cubing: Cut sweet potatoes into uniform, small cubes. This ensures they cook evenly and become tender at the same time as the other vegetables.
  • Don’t Overcook Eggs: Watch the baking time carefully. Overcooked eggs can become rubbery; they are done when they are set but still slightly moist.
  • Seasoning Layers: Season the vegetables, sausage, and egg mixture separately. This builds layers of flavor throughout the casserole, enhancing the overall taste.
  • Pre-cooking Sweet Potatoes: Partially cooking the sweet potatoes on the stovetop ensures they are tender when the casserole finishes baking. Don’t skip this step!
  • Casserole Dish Size: A 9×13-inch dish is ideal for this recipe. Using a dish that is too small can lead to overflow, while a dish too large might result in a dry casserole.

  • Provide a selection of toppings like sliced avocado, a dash of hot sauce, or a sprinkle of fresh cilantro for added flavor.

Make Ahead & Storage

This casserole is fantastic for meal prepping and busy mornings.

  • Overnight Prep: Prepare and cook the sweet potatoes, bell pepper, onion, and sausage the night before. Store these cooked ingredients separately in the refrigerator. In the morning, combine them in the casserole dish, pour the whisked egg mixture over, and bake. Do not add the eggs until just before baking.
  • Refrigeration: Store any leftover cooked casserole in an airtight container in the refrigerator for up to 3-4 days. Reheat individual portions in the microwave or oven.

Freezing Instructions

You can easily freeze this delicious casserole for future quick meals.

  • Unbaked: You can prepare the casserole up to the point of adding the eggs. Cover the dish tightly with plastic wrap and then foil. Freeze for up to 1 month. Thaw overnight in the fridge before adding eggs and baking as directed.
  • Baked: Allow the baked casserole to cool completely. You can freeze it whole or cut it into individual portions. Wrap tightly in plastic wrap and then foil, or place portions in freezer-safe containers. Freeze for up to 2-3 months.
  • Thawing & Reheating: Thaw frozen baked portions in the refrigerator overnight. Reheat in the microwave until warm or in a preheated oven at 350°F (175°C) until heated through.

Variations

Customize your sweet potato egg casserole with these delicious twists!

  • Cheesy Option: Sprinkle 1 cup of shredded cheddar or Monterey Jack cheese over the casserole before the final uncovered bake.
  • Spicy Kick: Add 1-2 diced jalapeños (seeds removed for less heat) to the vegetable mix or a pinch of red pepper flakes to the egg mixture.
  • Herb Boost: Stir in 2 tablespoons of fresh chopped parsley or chives with the egg mixture for a vibrant, fresh flavor.

Hi there, I’m chef living in New York City. Every morning, I wake up to the sounds of my little one’s laughter and the comforting routine of preparing breakfast for my family my husband, our child, and my beloved mother, who’s become both my rock and my inspiration since my father passed away. As the only daughter left in our family, I feel a deep responsibility to carry on his memory whenever I step into the kitchen.
