Breakfast Casserole Supreme: The Ultimate Crowd-Pleaser

My grandmother, Nana Rose, was a master of effortless entertaining, and her breakfast casseroles were legendary. I remember waking up to the savory aroma wafting from the kitchen on holidays, a comforting scent that promised a day filled with family, laughter, and delicious food. Nana Rose’s secret was simplicity and generosity; she always made sure there was enough for everyone, and her recipes were unfussy, designed to bring people together rather than stress out the cook. This Breakfast Casserole Supreme is my tribute to her, adapted from her original recipe, but with a few modern touches.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 50 minutes
• Total Time: 1 hour 10 minutes
• Servings: 12
• Yield: 1 9×13 inch casserole
• Dietary Type: Variable (can be modified for gluten-free)

Ingredients

• 1/4 cup margarine
• 1 small sweet onion, chopped
• 1 small green pepper, chopped
• 2-3 medium tomatoes, chopped
• 1 (24 ounce) bag frozen hash brown potatoes
• 12 eggs, beaten
• 1/2 lb cooked crumbled bacon or 1/2-1 lb sausage, cooked
• 3 cups cheddar cheese, shredded

Equipment Needed

• 9″ x 13″ baking pan
• Large mixing bowl
• Skillet or frying pan (if cooking sausage or bacon)
• Whisk
• Spatula

Instructions

1. Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius).
2. Melt the margarine and pour it into the bottom of your 9″ x 13″ baking pan. Ensure the entire bottom is coated lightly. This will prevent sticking and add a subtle richness to the bottom of the casserole.
3. Spread the frozen hash brown potatoes evenly across the bottom of the pan. It’s perfectly fine to use them straight from the freezer; they will thaw as the casserole bakes.
4. Sprinkle the chopped sweet onion and green pepper evenly over the potatoes.
5. Distribute the chopped tomatoes over the onions and peppers.
6. Season the potato and vegetable layer with salt and pepper to your liking. Don’t be shy; this layer needs proper seasoning!
7. Sprinkle the cooked crumbled bacon or cooked sausage evenly over the vegetables. If using sausage, make sure it’s thoroughly cooked and drained of any excess grease.
8. Note: At this point, you can either proceed with the recipe or cover the casserole tightly and refrigerate it overnight. This is a great make-ahead option for busy mornings.
9. Pour the beaten eggs evenly over the potato, vegetable, and meat layers. Make sure the eggs distribute throughout the entire casserole.
10. Bake in the preheated oven for 45 minutes.
11. Remove the casserole from the oven and sprinkle the shredded cheddar cheese evenly over the top.
12. Return the casserole to the oven and bake for another 5-10 minutes, or until the cheese is melted, hot, and bubbly.
13. Remove the casserole from the oven and let it rest for approximately 5 minutes before cutting. This allows the casserole to set slightly, making it easier to serve.
14. Cut the casserole into 2.5″-3″ squares and serve with a spatula. Enjoy!

Expert Tips & Tricks

• Even Cooking: To ensure even cooking, especially if your oven tends to have hot spots, rotate the casserole halfway through the baking time.
• Cheese Distribution: To prevent the cheese from browning too quickly, you can tent the casserole with foil during the last 5-10 minutes of baking.
• Flavor Boost: For an extra layer of flavor, consider adding a dash of hot sauce or a sprinkle of red pepper flakes to the egg mixture.
• Vegetable Prep: If you prefer softer vegetables, you can sauté the onions and peppers in a little olive oil before adding them to the casserole.
• Make-Ahead Magic: When making this casserole ahead of time, be sure to cover it tightly with plastic wrap before refrigerating it. This will prevent the potatoes from drying out and the eggs from absorbing any unwanted flavors from the refrigerator.

Serving & Storage Suggestions

Serve the Breakfast Casserole Supreme warm, directly from the oven. It pairs perfectly with a side of fresh fruit, a dollop of sour cream or salsa, and a cup of hot coffee or juice.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, simply microwave individual portions or bake the entire casserole in a preheated oven at 350 degrees Fahrenheit (175 degrees Celsius) until heated through.

While it’s safe to leave the casserole out at room temperature for up to two hours, prompt refrigeration is recommended to maintain its quality and safety. Freezing is also an option; cut the casserole into individual portions, wrap them tightly in plastic wrap, and then place them in a freezer-safe bag or container. Frozen casserole can last for up to 2-3 months. Thaw in the refrigerator overnight before reheating.

FAQs (Frequently Asked Questions)

Q: Can I use fresh potatoes instead of frozen hash browns?
A: Yes, you can. Peel and dice the potatoes into small pieces, then boil them until they are slightly tender before adding them to the casserole.

Q: Can I add milk or cream to the egg mixture?
A: While the recipe doesn’t call for it, you can add about 1/2 cup of milk or cream to the egg mixture for a slightly richer and creamier texture.

Q: How do I prevent the bottom of the casserole from sticking?
A: Be sure to grease the baking pan thoroughly with margarine or cooking spray. Alternatively, you can line the bottom of the pan with parchment paper.

Q: Can I use different types of cheese?
A: Absolutely! Feel free to experiment with different cheeses, such as mozzarella, pepper jack, or a blend of your favorites.

Q: How do I know when the casserole is done?
A: The casserole is done when the eggs are set and no longer jiggly in the center. You can also insert a knife into the center; if it comes out clean, the casserole is ready.
