Kitchen Tools Needed for This Oven Breakfast Casserole

Before getting started, gather the following tools:

• Large skillet
• Mixing bowls
• 9×13-inch baking dish
• Whisk
• Rubber spatula
• Aluminum foil (for covering if baking ahead)
• Airtight containers (for storing leftovers)

How to Make Crack Breakfast Casserole – Step-by-Step Instructions

1. Cook the sausage: In a large skillet, cook sausage over medium heat until browned and cooked through. Drain excess grease and set aside.
2. Prepare the hash browns: If using frozen hash browns, make sure they’re fully thawed. Pat dry with paper towels to remove excess moisture.
3. Mix the egg base: In a large mixing bowl, whisk together eggs, milk, garlic powder, onion powder, salt, and pepper. Beat until smooth.
4. Add the cream cheese: Mix in the softened cream cheese until well combined. Small lumps are fine — they’ll melt into the casserole during baking.
5. Assemble the casserole: In a greased 9×13-inch baking dish, layer hash browns evenly on the bottom. Top with the cooked sausage and shredded cheese. Pour the egg mixture over the top.
6. Bake: Preheat the oven to 350°F (175°C). Bake uncovered for 40–45 minutes, or until the center is set and the top is golden.
7. Cool and serve: Let sit for 5–10 minutes before slicing. Garnish with chopped green onions or herbs if desired.

Just like that, your crack breakfast casserole is hot, bubbly, and ready to serve.

Ham and Sausage Breakfast Casserole Variations

Want to level up your breakfast casserole game? Try these ideas:

• Add both ham and sausage for double the meaty flavor.

• Incorporate cooked sweet potatoes or roasted veggies for a nutrition boost.
• Top with crushed Ritz crackers or cornflakes before baking for a crispy finish.

Or take a sweeter turn by serving it alongside a batch of Pumpkin Cinnamon Rolls for a holiday-worthy brunch menu.

Common Mistakes to Avoid With Premade Breakfast Casseroles

• Not draining the sausage: Extra grease can cause the casserole to be soggy.
• Using cold hash browns: Always thaw and drain before assembling.
• Overbaking: This can dry out the eggs. Start checking for doneness at 40 minutes.
• Not seasoning enough: Eggs and potatoes need flavor — don’t skimp on the spices.

Avoiding these missteps ensures your premade breakfast casserole tastes fresh, even if it’s been chilled or frozen.

Serving Suggestions for This Fast Breakfast Casserole

Turn this dish into a complete breakfast spread with:

• Fresh fruit or yogurt parfaits
• A pot of coffee or herbal tea
• Pumpkin Baked Oatmeal or Brown Sugar Overnight Oats on the side
• Simple avocado toast
• Salsa or hot sauce for a spicy topping

It’s hearty enough to stand on its own, but versatile enough to serve with sweet or savory sides.
