The pressure builds and you start counting down minutes until you eat. You can practically smell that sizzle from the bacon and sausage in the air. It’s that kinda morning when you wanna skip the fuss and get straight to the good stuff.

You spot the layers of bread soaking up the egg mixture and know this casserole’s gonna be rich and tender. The float valve just lifted a bit so you know the broth depth inside is enough to keep things moist but not soggy. The valve hiss when you release pressure later is gonna be sweet relief.
As you wait for the natural release to finish, you sense that cozy warmth filling your kitchen. You recall how easy it was to toss everything together last night before bed. This overnight method kinda makes mornings feel like a treat instead of a rushed mess.

- The broth depth inside lets the casserole steam evenly without drying out.
- Natural release helps the eggs set perfectly, no rubbery edges here.
- You’ll hear the valve hiss which tells you the pressure’s releasing, so don’t rush removing the lid.
- Float valve shows when it’s safe to peek inside making the timing easier to trust.

- The quick pressure build ups mean you ain’t spending forever waiting around.
All the Pieces for This Meal
- 6 large eggs - your base for that custardy texture.
- 2 cups whole milk - gives creaminess and helps everything bind.
- 1 teaspoon mustard - just enough twist to brighten the taste.
- 1 teaspoon salt - brings out all those flavors.
- ½ teaspoon freshly cracked pepper - for that little punch.
- 6 slices white bread, cubed - soaking up all the yum.
- 1 ½ cups shredded cheddar cheese, with extra for topping - sharp and melty.
- 16 oz breakfast sausage, cooked and drained - hearty and seasoned.
- 8 oz bacon, cooked and chopped - adds that smoky, crispy goodness.

Your Complete Cooking Timeline
First, you gotta preheat your oven to 350°F (175°C). This is to get it ready for that final bake which seals all the flavors. You’ll finish things in the oven after the pressure cooker step for that nice golden top.
Next, whisk together eggs, milk, mustard, salt, and pepper in a large bowl. It’s kinda fun watching it blend into this silky mixture that’ll soak into everything.
In a greased 9x13 inch baking dish, layer the cubed bread evenly so every bite has a good base. Then sprinkle the cooked sausage and chopped bacon all over the bread layer. You want those meaty bits spread out so every forkful sings.
Sprinkle the shredded cheddar on top of the meat layer, then pour the egg mixture evenly over the whole thing. Cover tightly with plastic wrap and refrigerate overnight. This is the easiest part cause you just walk away and trust it.
In the morning, pull the casserole out and let it sit at room temperature 15 minutes. That helps it warm just enough before cooking so you don’t get weird spots that are too cold.
Remove the plastic wrap and throw some more cheese on top if you wanna — extra cheesy mornings are the best mornings. Then pop it in the oven uncovered for 45-50 minutes till it’s set and golden brown.
Once it’s out, let it cool a few before slicing. This rest step is key to hold everything together.
Time Savers That Actually Work
- Cook the bacon and sausage the night before when you make the casserole prep. Saves time in the morning so you ain’t rushing.
- Use pre-shredded cheddar if you don’t wanna pull out the grater. It works real good and saves clean up.
- Pre-cube your bread the night before too so assembly is a breeze when you’re tired.

That First Bite Moment
When you finally take that first bite, the warm custardy eggs greet your taste buds soft and comforting. They’re packed with bacon and sausage flavor that makes your mouth sing.
You notice the cheddar cheese melted into gooey pockets, adding a sharp richness to every forkful. The bread soaked up the egg goodness so it's tender but with a slight chew.
Each bite is kinda like a cozy morning hug that gets you ready to tackle the day. You’re gonna wanna make this one regular around here.
Making It Last All Week Long
Store leftovers in an airtight container in the fridge. It stays good up to 4 days so you can keep enjoying those flavors.
To reheat, zap a serving in the microwave for about 1-2 minutes till hot. It’s quick and keeps it moist.
Alternatively, reheat in the oven at 350°F for 10-15 mins covered with foil if you want it warm and a little crisp.
If you wanna freeze, cut into portions and wrap tightly with plastic wrap and foil. Freeze for up to 2 months. Thaw overnight in the fridge before reheating.
Common Questions and Real Answers

- Can I prep this all same day? Absolutely. Just give it a little time to soak before baking so it doesn't turn out dry.
- What’s the broth depth mean here? It’s the liquid level that makes sure the casserole is steamed nice and tender inside your pressure cooker.
