Ingredients List

This Simple Breakfast Casserole with Hash Browns and Bacon comes together with straightforward, comforting ingredients you likely have on hand or can easily grab. The beauty is in how they all bake together into something greater than the sum of its parts.

• 1 (30 oz) bag frozen shredded hash browns, thawed
• 12 large eggs
• 1 cup whole milk
• 1 lb bacon, cooked until crisp and crumbled
• 2 cups shredded sharp cheddar cheese, divided
• 1 cup shredded Monterey Jack cheese
• 1 medium yellow onion, diced
• 1 red bell pepper, diced
• 3 green onions, thinly sliced (white and green parts separated)
• 1 teaspoon garlic powder
• 1 teaspoon smoked paprika
• 1/2 teaspoon black pepper
• 1/2 teaspoon salt (adjust to taste, as bacon adds saltiness)
• Cooking spray or butter for greasing

Smart Swaps & Notes:

• Hash Browns: A bag of frozen diced potatoes works just as well for a different texture. For a from-scratch touch, you can shred your own russet potatoes, but be sure to rinse and thoroughly dry them to remove excess starch.
• Bacon: This is where you can personalize your Simple Breakfast Casserole. Swap the bacon for 1 lb of breakfast sausage (mild or spicy) browned and drained. For a Sausage Breakfast Casserole Recipes variation, it’s a direct and delicious swap.
• Cheese: Use what you love! A Colby-Jack blend is fantastic. For a kick, swap a cup of the cheddar for pepper Jack. For a dairy-free version, use your favorite plant-based shreds and milk.
• Veggies: Feel free to add in 8 oz of sliced mushrooms sautéed with the onion, or a handful of fresh spinach stirred into the egg mixture.

Timing

One of the best things about this Pre Made Breakfast Casserole is how the timing works in your favor.

• Prep Time: 20 minutes (mostly chopping and mixing)
• Cook Time: 55-65 minutes
• Total Time: About 1 hour 20 minutes
• Make-Ahead Bonus: You can assemble the entire casserole the night before, cover, and refrigerate. Just add 5-10 minutes to the bake time the next morning. This makes it about 100% less stressful for a special morning.

Step-by-Step Instructions

Follow these simple steps for a perfectly set, golden-brown Simple Breakfast Casserole with Hash Browns and Bacon every single time.

1. Prep and Preheat. Grease a 9×13 inch baking dish generously with butter or cooking spray. Preheat your oven to 375°F (190°C). This ensures a hot, even cooking environment for your Hashbrown Casserole base.
2. Build the Base. In a large bowl, combine the thawed hash browns, the cooked and crumbled bacon (reserve a small handful for topping if you like), 1 1/2 cups of the cheddar cheese, the Monterey Jack cheese, diced yellow onion, red bell pepper, and the white parts of the green onions. Toss everything together until evenly distributed. Transfer this mixture to your prepared baking dish and press it down into a fairly even layer. This creates the flavorful foundation.
3. Whisk the Custard. In that same large bowl (fewer dishes!), whisk the eggs, milk, garlic powder, smoked paprika, black pepper, and salt until completely smooth and uniform. The goal is a homogenous, pale yellow mixture. This custard is what binds our Simple Breakfast Casserole with Hash Browns and Bacon together.
4. Pour and Top. Slowly and evenly pour the egg custard over the hash brown mixture in the baking dish. Use a fork to gently poke and lift the hash browns in a few spots to help the egg mixture seep down into every nook and cranny. Top with the remaining 1/2 cup of cheddar cheese and the reserved bacon bits (if using).
5. Bake to Perfection. Place the casserole in the preheated oven and bake for 55 to 65 minutes. You’re looking for the edges to be golden brown and puffed, and the center to be completely set. A knife inserted into the center should come out clean. If the top is browning too quickly, you can tent it loosely with foil for the last 10-15 minutes of baking.
6. Rest and Serve. This is a crucial step! Let the casserole rest on a cooling rack for 10-15 minutes before slicing. This allows the eggs to fully set, making for clean slices that hold their shape. Garnish with the green parts of the sliced green onions.

Healthier Alternatives for the Recipe

You can easily tweak this Simple Breakfast Casserole with Hash Browns and Bacon to fit different dietary needs without sacrificing flavor.

• Lower-Carb/Gluten-Free: Replace the hash browns with 4 cups of riced cauliflower (thawed and squeezed very dry). The texture will be different but still delicious. All other ingredients are naturally gluten-free.
• Lighter/Dairy-Free: Use 2% milk or unsweetened almond milk. Swap the cheeses for a dairy-free shred blend. You can also reduce the cheese by 1 cup overall for a lighter version.
• Higher-Protein: Add 1 cup of small-curd cottage cheese to the egg mixture when whisking. It melts into the custard, adding creaminess and a protein boost without a strong flavor.

• Bread Basket: Buttery biscuits, flaky croissants, or slices of toasted artisan bread are perfect for sopping up any delicious bits.

Common Mistakes to Avoid

A few small tips can guarantee your Simple Breakfast Casserole with Hash Browns and Bacon turns out perfect.

1. Not Thawing the Hash Browns: Using frozen hash browns straight from the freezer will make your bake time much longer and can result in a watery casserole. Take the time to thaw them—overnight in the fridge or spread on a tray at room temp for an hour.
2. Skipping the Rest Time: Cutting into the casserole right out of the oven is tempting, but it will be soupy and fall apart. Letting it rest for 10-15 minutes allows the egg proteins to fully set, giving you those beautiful, clean slices.
3. Underseasoning the Custard: The hash browns and bacon need help from the egg mixture. Don’t be shy with the garlic powder, paprika, and pepper. Taste your custard mix (a tiny sip!) before pouring—it should be well-seasoned.
4. Overbaking: An overbaked casserole can become dry and rubbery. Start checking at 55 minutes. The center should be just set, with no liquid jiggle, but it will continue to cook slightly as it rests.

Storing Tips for the Recipe

This Simple Breakfast Casserole with Hash Browns and Bacon is a meal prep dream.

• Refrigerating Leftovers: Cool completely, then cover tightly with plastic wrap or transfer slices to an airtight container. It will keep in the fridge for 3-4 days.
• Freezing: For a true Pre Made Breakfast Casserole option, you can freeze it baked or unbaked. Baked: Cool completely, wrap the whole dish or individual portions tightly in plastic wrap and then foil. Freeze for up to 2 months. Unbaked: Assemble but do not bake. Wrap tightly and freeze. Thaw overnight in the refrigerator before baking as directed, adding a few extra minutes as needed.
• Reheating: Reheat individual slices in the microwave for 60-90 seconds until hot. For larger portions, cover with foil and reheat in a 350°F oven for 15-20 minutes, or until warmed through. This helps retain the best texture.
