Key Ingredients & Substitutions
Potatoes: Use russet or Yukon Gold potatoes; they hold up well and get crispy. You can also swap for frozen diced potatoes for convenience. Just adjust the cooking time slightly!
Bell Peppers: The mix of green and red gives color and flavor. If you prefer, you can substitute with yellow or orange peppers. For a spicier kick, try using jalapeños!
Cheddar Cheese: Shredded sharp cheddar adds great flavor. If you want a milder taste, use Monterey Jack or mozzarella instead. Vegan cheese is also a good alternative if you’re looking for a dairy-free option.
Bacon: While bacon adds heartiness, feel free to use turkey bacon or omit it completely for a vegetarian option. You could also replace it with sautéed mushrooms for extra flavor.
Green Onions: These add freshness and crunch. If you don’t have them, chopped chives work nicely, or a dash of onion powder can be used in a pinch!
How Do You Get Perfectly Cooked Casserole Eggs?
Cooking the eggs just right is key. To achieve that fluffy texture, whisk eggs thoroughly before mixing them with the other ingredients. The milk adds creaminess, so don’t skip it.
- Ensure the skillet is at medium heat for sautéing; you want soft potatoes, not burnt ones!
- Take care not to overcrowd the casserole dish; this will ensure even cooking.
- Let it cool for a few minutes after baking to allow the eggs to set fully, making it easier to slice.
Following these tips will help ensure your casserole is a crowd-pleaser every time! Enjoy your delicious breakfast dish!
How to Make Potatoes O’Brien Breakfast Casserole
Ingredients You’ll Need:
For the Casserole:
- 4 cups diced potatoes (about 3 medium potatoes)
- 1/2 cup diced green bell pepper
- 1/2 cup diced red bell pepper
- 8 large eggs
- 1 cup shredded cheddar cheese
- 1/2 cup cooked and crumbled bacon (plus extra for topping)
- 1/2 cup chopped green onions (plus extra for garnish)
- 1/4 cup milk
- Salt and pepper, to taste
- 2 tablespoons butter or oil for sautéing
How Much Time Will You Need?
This tasty breakfast casserole will take you about 15 minutes to prep and 25-30 minutes to bake. So, in total, you’re looking at around 45 minutes before you can enjoy this delicious meal!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). While it’s heating up, lightly grease a medium-sized casserole dish to keep the casserole from sticking.
2. Sauté the Potatoes:
In a large skillet, heat up the butter or oil over medium heat. Once hot, add the diced potatoes. Sauté them for about 10-12 minutes, stirring occasionally, until they’re golden and crispy. We want them to be tender but not mushy!
3. Add the Peppers:
Next, toss in the diced green and red bell peppers. Cook this mixture for an additional 3-4 minutes, or until the peppers have softened. Once done, remove the skillet from the heat and set it aside.
4. Whisk the Eggs:
In a large bowl, whisk together the eggs, milk, salt, and pepper until everything is well combined. This will be the base of your casserole!
5. Combine Everything:
Gently fold in the sautéed potatoes and peppers, along with the cooked bacon, 1/2 cup of shredded cheddar cheese, and chopped green onions. Make sure everything is evenly mixed.
6. Pour into Casserole Dish:
Pour the potato mixture into the greased casserole dish and spread it out evenly. This ensures that it cooks uniformly.
7. Add the Toppings:
Now, sprinkle the remaining cheddar cheese and some extra bacon pieces on top for that delicious finishing touch.
8. Bake:
Place the casserole in the preheated oven and bake for 25-30 minutes. You’ll know it’s done when the eggs are set and the top is beautifully golden brown.
9. Let it Cool:
Once removed from the oven, let the casserole cool for a few minutes. This will help it hold together better when you serve it.
10. Serve and Enjoy:
Before serving, sprinkle some extra chopped green onions on top to add freshness. Now, dig in and enjoy your homemade Potatoes O’Brien Breakfast Casserole!
Can I Use Frozen Diced Potatoes?
Yes, frozen diced potatoes are a convenient option! Just ensure to thaw and drain them before using to avoid excess moisture in the casserole. You may need to reduce the sautéing time slightly as they will soften quickly.
How Long Does This Casserole Last in the Fridge?
Your Potatoes O’Brien Breakfast Casserole will last in the refrigerator for up to 3 days when stored in an airtight container. To reheat, simply warm it in the microwave or oven until heated through.
Can I Make This Casserole Overnight?
Absolutely! You can prepare the casserole the night before and keep it covered in the refrigerator. Just bake it the next morning; it may take a few extra minutes in the oven since it will be cold from the fridge.
What Can I Add for Extra Flavor?
For an extra burst of flavor, consider adding spices like paprika or smoked paprika, garlic powder, or even a dash of hot sauce to the egg mixture. Fresh herbs like parsley or cilantro can also enhance the taste!
