Potato, Sausage and Broccoli Breakfast Casserole

The Ultimate Weekend Breakfast That'll Feed a Crowd

Alright, let me tell you about the breakfast casserole that changed everything. I used to think breakfast casseroles were just for holidays you know, the thing your aunt brings to Easter brunch that's good but kind of basic. Then I created this Potato, Sausage and Broccoli Breakfast Casserole, and folks? It's anything but basic.

This is the breakfast that dreams are made of. Savory Italian sausage, crispy golden potatoes, tender broccoli, and sharp cheddar cheese all baked together in a fluffy, creamy egg custard. It's hearty, it's satisfying, and it feeds a crowd. My family goes absolutely nuts for this every time I make it.

The first time I made this, I was just trying to use up some leftover sausage and a potato that was about to go bad. I threw in some broccoli, some cheese, and some eggs, and suddenly I had created breakfast magic. My kids asked for seconds (and thirds). My wife said it was the best breakfast casserole she'd ever had. Even my picky father-in-law went back for more.

The best part? It comes together in about 55 minutes, most of which is hands-off baking time. Perfect for lazy weekends, holiday mornings, or any time you want to impress without the stress. You can even prep it the night before and just pop it in the oven!

So grab your sausage, your potatoes, and your cheese. Let's make the best breakfast casserole of your life!

What You'll Need to Do

Alright, my friends. This casserole is so good, you'll want to make it every weekend. Let's get cooking!

Step 1: Fire up that oven. Preheat to 350°F. Grab your 8x8-inch baking dish and give it a good spray with non-stick cooking spray. Don't skip this we want easy cleanup!

Step 2: Brown that sausage. Set a large skillet over medium heat and add your Italian sausage. Cook for about 3-4 minutes, breaking it up with a wooden spoon as it cooks. You want it slightly browned and crumbly.

Step 3: Add the veggies. Toss in the diced onion and potato. Season with a good pinch of salt and a crack of black pepper. Cook for about 6-7 minutes, stirring occasionally, until the onion is soft and the potatoes are beautifully golden brown. Your kitchen will smell AMAZING.

Step 4: Whisk the egg mixture. In a small bowl, whisk together the eggs and whole milk. Season with salt and pepper. Stir in ½ cup of the shredded cheddar cheese and mix until combined.

Step 5: Assemble the casserole. Transfer that gorgeous sausage-potato mixture into your prepared baking dish. Stir in the diced broccoli and spread everything into an even layer. Pour the egg mixture evenly over the top. Sprinkle the remaining ¼ cup of cheese across the top.

Step 6: Bake to perfection. Pop that dish in the oven and bake for 25-30 minutes, until the casserole is set and the top is golden and bubbly. A knife inserted in the center should come out clean.

Step 7: Garnish and serve. Remove from the oven and let it rest for about 5 minutes. Sprinkle with fresh chives. Slice it up and serve warm. Watch it disappear!

Some Helpful Tips

• Brown the sausage well – That browned flavor adds so much depth.
• Don't rush the potatoes – Let them get golden and crispy.
• Dice potatoes evenly – Uniform pieces = even cooking.
• Use room temperature eggs – They incorporate better into the custard.
• Don't overbake – The casserole should be just set in the center.
• Let it rest – Gives the casserole time to set up before serving.
• Fresh chives at the end – Adds bright, fresh flavor.
• Season each layer – Salt and pepper at each step for maximum flavor.

Some Budget-Friendly Tips

Feeding a crowd on a budget? Here's how I save:

• Buy sausage in bulk – Bulk Italian sausage is cheaper than links.
• Use potatoes – One of the cheapest, most filling ingredients.
• Buy cheese in blocks – Shred your own it's cheaper and melts better.
• Use frozen broccoli – Often cheaper than fresh and works great.
• Make a double batch – Extra casserole = extra meals.
• Use what you have – Any onion, any potato, any cheese works.
• Watch for sales – Buy sausage and cheese when on sale.
• Substitute sausage – Ground pork with Italian seasoning is cheaper.

Some Serving Ideas

This casserole is a meal on its own, but here are some pairing ideas:

• As is – Perfect on its own with a side of fruit.
• With toast – Sourdough or whole grain toast on the side.
• Fresh fruit – Berries or melon balance the savory.
• Side salad – A simple green salad with vinaigrette.
• Hot sauce – A dash of hot sauce adds a nice kick.
• With avocado – Creamy avocado on the side.
• For dinner – Serve with a side salad and crusty bread.
• Brunch spread – Part of a larger brunch with pastries and juice.

Some Storage and Reheating Tips

• Refrigerate – Store in an airtight container for up to 4 days.
• Freeze – Freezes well for up to 3 months. Let cool completely first.
• Reheat – Microwave individual portions or reheat in a 350°F oven for 15-20 minutes.
• Make ahead – Assemble the night before, refrigerate, and bake in the morning (add 10 minutes).
