Ingredients
Scale
Main Ingredients
- 4 cups yellow potatoes, diced into small, even cubes
- 1 cup red bell pepper, chopped
- 1 cup green bell pepper, chopped
- 1 medium onion, chopped
- 6 large eggs
- 1 ½ cups sharp cheddar cheese, shredded
- Salt, to taste
- Black pepper, to taste
- 2 tablespoons olive oil or butter
Optional Ingredients
- 1 teaspoon paprika or smoked paprika (optional)
- Cooked bacon, sausage, or ham (for meat lovers)
- Mushrooms, spinach, or zucchini (for vegetarian variation)
- Plant-based cheese alternative (for dairy-free option)
- Diced jalapeños or hot sauce (to spice it up)
- Mozzarella or pepper jack cheese (for cheese variations)
Instructions
- Prep the vegetables and potatoes: Dice the yellow potatoes into small, even cubes for consistent cooking. Chop the red and green bell peppers and onion. Sauté the potatoes, peppers, and onion in olive oil or butter over medium heat until the potatoes are crisp on the outside and tender inside, and the peppers and onions have softened.
- Beat the eggs and season: In a bowl, whisk together the eggs with salt, pepper, and optional paprika or smoked paprika. This egg mixture will bind all the ingredients together with a creamy texture.
- Combine ingredients in a baking dish: Transfer the sautéed potatoes, peppers, and onions into a greased casserole dish. Pour the beaten eggs evenly over the mixture. Sprinkle shredded sharp cheddar cheese on top to form a golden, melty crust when baked.
- Bake until golden and set: Bake the casserole at 375°F (190°C) for 25-30 minutes or until the eggs are fully set and cheese is bubbling and lightly browned. Let cool for 5-10 minutes before slicing to help the casserole firm up and make serving easier.
Notes
- Cut potatoes uniformly to ensure even cooking and crispiness.
- Use a non-stick skillet to prevent vegetables from sticking and burning.
- Whisk eggs gently to avoid tough or rubbery texture in the casserole.
- Parboil or microwave potatoes before sautéing for faster cooking and softer interiors.
- Let the casserole rest before slicing to achieve clean, neat pieces.
