How to Make Fireman’s Breakfast Casserole
Step 1: Preheat and Prepare
First things first, preheat your oven to 350°F (175°C). While that’s warming up, grab a 9×13-inch baking dish and grease it with butter or nonstick spray. This step is crucial to ensure your Fireman’s Breakfast Casserole comes out easily and doesn’t stick. Trust me, no one wants a casserole disaster!
Step 2: Cook the Sausage and Vegetables
In a large skillet over medium heat, cook the breakfast sausage until it’s browned and crumbly. This usually takes about 5-7 minutes. Once the sausage is cooked, toss in the finely chopped onion and bell pepper. Sauté them together until the veggies are softened, about another 5 minutes. The aroma will be irresistible, and your kitchen will feel like a cozy diner!
Step 3: Layer the Hash Browns and Cheese
Now, let’s build our masterpiece! Spread the thawed hash browns evenly across the bottom of your greased baking dish. This crispy layer is the foundation of your Fireman’s Breakfast Casserole. Next, sprinkle half of the shredded cheddar cheese over the hash browns. This cheesy goodness will melt into the layers, creating a delightful surprise!
Step 4: Whisk the Egg Mixture
In a large bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, black pepper, and paprika until smooth. This mixture is what binds everything together, creating that fluffy texture we all love. Make sure it’s well combined; you want every bite to be packed with flavor!
Step 5: Assemble and Bake
Pour the egg mixture evenly over the sausage and hash brown layers in the baking dish. Don’t be shy; make sure it covers everything! Finally, sprinkle the remaining cheddar cheese on top. Bake uncovered for 40-45 minutes, or until the center is set and the top is golden and bubbly. Your kitchen will smell heavenly, and you’ll be counting down the minutes until you can dig in!

Tips for Success
- Prep the night before: Assemble the casserole and refrigerate it overnight. Just add 10 extra minutes to the baking time!
- Use fresh ingredients: Fresh eggs and quality sausage make a noticeable difference in flavor.
- Don’t skip the resting time: Let the casserole sit for 10 minutes after baking. This helps it set and makes cutting easier.
- Experiment with spices: Feel free to add your favorite herbs or spices for a personal touch!
Equipment Needed
- 9×13-inch baking dish: A standard size for casseroles. If you don’t have one, a similar-sized dish will work.
- Large skillet: Essential for cooking the sausage and veggies. A nonstick pan is a great alternative.
- Mixing bowl: For whisking the egg mixture. Any large bowl will do!
- Whisk: To combine the ingredients smoothly. A fork can work in a pinch.
