• 1 cup baby spinach, chopped

• 1 teaspoon garlic powder
• ½ teaspoon smoked paprika
• Salt and pepper to taste
• Non-stick spray or olive oil for greasing

Ingredient Notes and Variations

• Sweet Potatoes: These form the hearty base of this casserole. Shred them fresh or use pre-shredded sweet potatoes from the store.
• Veggies: Bell pepper, zucchini, spinach, and onion add fiber and nutrients. You can swap in broccoli, mushrooms, or whatever’s in season.
• Eggs: The ultimate protein booster. This recipe uses 6, but you can add more for extra protein like in our keto sausage breakfast casserole.
• Milk: Any milk works — almond, oat, or regular dairy.

Kitchen Equipment You’ll Need

• 9×9 or 9×13-inch baking dish
• Large mixing bowl
• Skillet
• Grater (for shredding sweet potatoes)
• Whisk or fork
• Measuring cups and spoons
• Non-stick spray or parchment paper

Step-by-Step Preparation: How to Make Protein-Packed Sweet Potato Egg Casserole

Step 1: Preheat your oven to 375°F (190°C). Lightly grease a baking dish with non-stick spray or olive oil.

Step 2: In a large skillet, heat olive oil over medium heat. Add red onion, bell pepper, and zucchini. Sauté for 5–6 minutes until veggies are slightly softened.

Step 3: Stir in the chopped spinach and cook for 1–2 more minutes until wilted. Remove from heat and let cool slightly.

Step 4: In a large mixing bowl, combine shredded sweet potatoes, sautéed veggies, garlic powder, paprika, salt, and pepper. Mix well.

Step 5: In a separate bowl, whisk together eggs and milk. If using cheese, stir it into the egg mixture.

Step 6: Add the egg mixture into the sweet potato-veggie blend and stir until evenly combined.

Step 7: Pour everything into your greased baking dish and smooth the top with a spatula.

Step 8: Bake uncovered for 35–40 minutes or until the center is set and edges are golden. Let rest 5–10 minutes before slicing.

Step 9: Serve warm, topped with herbs, avocado slices, or a drizzle of hot sauce if desired.

Pro Tips for the Best Sweet Potato Egg Casserole

• Shred your sweet potatoes finely so they cook evenly and bind well with the eggs.
• Sauté the veggies first to remove moisture and enhance flavor.
• Use parchment paper for easy cleanup and non-stick results.
• Want more crunch? Top with crushed almonds or pumpkin seeds before baking.
• Turn it into a portable option by baking in muffin tins like these mini frittata cups.

Common Mistakes to Avoid

• Using raw dense veggies – always sauté or pre-cook harder vegetables before mixing.
• Not draining excess liquid – wet veggies or watery cheese can make the casserole soggy.
• Skipping seasoning – don’t forget salt, pepper, and spices for balanced flavor.
• Overbaking – it can dry out the eggs. Check for doneness around the 35-minute mark.
