Key Ingredients & Substitutions
Frozen Diced Potatoes O’Brien: These are a mix of diced potatoes with green and red peppers, making them super convenient. If you don’t have this, you can use frozen hash browns or diced fresh potatoes sautéed with bell peppers.
Eggs: The main binding ingredient! I recommend using large eggs for the best results. You can replace them with egg substitutes if you’re watching cholesterol or need a vegan option, though the texture might change.
Cheddar Cheese: I chose sharp cheddar for its strong flavor. You could also try Monterey Jack, Colby, or even a dairy-free cheese if you’re looking for alternatives.
Bacon or Ham: These add a wonderful smoky taste. You can leave them out for a vegetarian option or use turkey bacon or sausage for a leaner choice!
What’s the Best Way to Ensure Your Eggs Are Fully Set?
Getting perfectly cooked eggs in your casserole is key. Here’s how to do it:
- Whisk your egg mixture well; this incorporates air and helps them puff up.
- Bake at the recommended temperature and check for doneness around the 35-minute mark. The eggs should look firm, not runny.
- Let the casserole rest after baking; this helps it set up and makes it easier to cut into squares.
Trust me; patience will ensure great texture and flavor in every bite!
Potatoes O’Brien Breakfast Casserole
Ingredients You’ll Need:
For the Casserole:
- 4 cups frozen diced potatoes O’Brien (with green and red peppers, thawed)
- 8 large eggs
- 1 cup milk
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1 cup shredded cheddar cheese, divided
- 1/2 cup chopped cooked bacon or ham (optional)
- 1 tablespoon chopped fresh parsley, for garnish (optional)
- Butter or cooking spray for greasing the baking dish
How Much Time Will You Need?
This delicious breakfast casserole takes about 15 minutes to prepare and 35-45 minutes to bake. You’ll have total hands-on time of around 15 minutes, followed by easy baking time in the oven. It’s a fantastic make-ahead dish too, so you can enjoy a leisurely morning!
Step-by-Step Instructions:
1. Prepare the Oven and Dish:
Start by preheating your oven to 350°F (175°C). Grab a 9×13-inch baking dish and grease it with butter or cooking spray to prevent sticking.
2. Layer the Potatoes:
Take the thawed diced potatoes O’Brien and spread them evenly in the bottom of your greased baking dish. This will be the base of your delicious casserole.
3. Make the Egg Mixture:
In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, garlic powder, and onion powder. Make sure it’s well combined; this will be the fluffy part of your casserole!
4. Combine the Layers:
Pour the egg mixture uniformly over the potatoes in the baking dish, allowing it to soak through the potatoes. This will help everything flavorfully come together.
5. Add Cheese and Meat:
Now sprinkle half of the shredded cheddar cheese over the egg and potato mixture. If you like, add the chopped cooked bacon or ham on top for a savory kick. Finally, top everything with the remaining cheddar cheese—this will give you that golden, bubbly finish!
6. Bake to Perfection:
Place your baking dish in the preheated oven and bake for 35-45 minutes. Keep an eye out! You want the eggs to be set and the cheese to be melted and bubbly.
7. Cool and Serve:
Once baked, remove the casserole from the oven and let it sit for about 5 minutes. This waiting time helps it set and makes it easier to cut. When you’re ready, garnish with chopped fresh parsley if you like and serve warm. Enjoy every bite of this cheesy goodness!
Bon appétit and enjoy your delightful Potatoes O’Brien Breakfast Casserole—perfect for any brunch gathering or a cozy breakfast at home!
Can I Use Fresh Potatoes Instead of Frozen?
Yes, you can! If using fresh potatoes, peel and dice them into small cubes, then cook them in a skillet with a bit of oil until they’re tender before layering in the baking dish. This will ensure they cook properly in the casserole.
Can I Make This Casserole the Night Before?
Absolutely! You can prepare the entire casserole up to the baking step, cover it well, and refrigerate overnight. In the morning, just pop it in the oven straight from the fridge; you may need to add a few extra minutes to the baking time.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, microwave individual portions or warm in the oven until heated through. It’s great for quick breakfast options!
Can I Add Other Veggies?
Definitely! Feel free to mix in other vegetables like spinach, mushrooms, or zucchini. Just make sure to sauté any fresh vegetables first to remove excess moisture before adding them to the casserole. This will keep your casserole from becoming soggy!
