Sausage Breakfast Casserole Recipe
Grandma’s Kitchen & the Birth of a Breakfast Legend
Picture 8-year-old me, perched on a wobbly stool in Grandma’s kitchen, “supervising” her every move. (Spoiler: I was mostly sneaking cheese.) Her Sausage Breakfast Casserole was legendary—a Sunday ritual that brought our rowdy family together like clockwork. One time, I convinced her to let me crack the eggs… and let’s just say eggshells became an unexpected “crunchy topping.” We laughed so hard we forgot to care. Years later, when I moved into my first apartment, Grandma mailed me the recipe scribbled on a napkin with a post-it: “Don’t forget the mustard powder, kiddo.” Now, every time I bake this casserole, I swear I can hear her whispering, “Let it rest, or you’ll burn your tongue!” Some recipes aren’t just food—they’re time machines.
What You’ll Need (And Why It All Works)
- 1 lb breakfast sausage – Go spicy for a kick or mild for crowd-pleasing vibes. Vegetarian? Swap in plant-based crumbles!
- 6 large eggs – Farm-fresh if possible! They’re the glue holding this delicious mess together.
- 2 cups milk – Whole milk = extra creamy. Dairy-free? Almond or oat milk works too.
- 1 tsp salt – Enhances allll the flavors. Trust me, it’s not the same without it.
- ½ tsp black pepper – Freshly cracked if you’re feeling fancy.
- 1 tsp dry mustard – Grandma’s secret weapon! Adds depth without being “mustardy.”
- 6 cups cubed bread – Stale sourdough = MVP here. No stale bread? Toast fresh cubes for 10 mins first!
- 1 ½ cups shredded cheddar – Sharp cheddar rules, but Gouda or pepper jack are fun twists.
- Optional add-ins – Toss in diced bell peppers, mushrooms, or spinach for bonus nutrients (and color!).
Let’s Build Breakfast Magic: Step-by-Step
Step 1: Preheat that oven to 350°F (175°C). Grease your 9×13 dish like you’re frosting a cake—every corner matters! Chef hack: Use butter for extra flavor or cooking spray for ease.
Step 2: Brown the sausage in a skillet over medium heat. Break it into small crumbles—it’s oddly therapeutic, right? Drain the grease (but leave a tablespoon for flavor!). Pro tip: Deglaze the pan with a splash of milk later to grab those tasty browned bits!
Step 3: In a large bowl, whisk eggs, milk, salt, pepper, and mustard powder like you’re conducting an orchestra. Secret weapon: Add a dash of hot sauce here if you’re into subtle heat!
Step 4: Layer your bread cubes in the dish—press them down slightly so they soak up that custard goodness. Top with sausage and 1 cup of cheese. Repeat if you’re feeling extra.
Step 5: Pour the egg mixture evenly over everything. Use a fork to gently press any floating bread cubes into the liquid. No swimmers allowed!
Step 6: Cover with foil and refrigerate overnight (ideal for flavor fusion!) or bake immediately. Time-saver: Assemble this the night before while sipping wine—morning-you will send thank-you texts.
Step 7: Bake uncovered 40–45 minutes until the center is set and edges are golden. Let it rest 10 minutes—this is non-negotiable for perfect slices! Sprinkle remaining cheese on top during the last 5 minutes for a gooey finish.
Plating Like a Pro (Pajamas Optional)
Slide a spatula under a generous square, plate it with fresh fruit or crispy hash browns, and garnish with chopped chives or a drizzle of hot honey. Serve with a side of “How did you make this?!” compliments.
Mix It Up: 5 Delicious Twists

Confessions from My Kitchen
True story: I once forgot to grease the dish and spent 20 minutes chiseling out “casserole croutons.” Learn from my mistakes! Over the years, I’ve added hot sauce to the custard, tried bacon (controversial but delicious), and even baked it in muffin tins for grab-and-go bites. The beauty? This recipe is as flexible as your yoga instructor. Make it yours!
Your Questions, My Answers
Q: Can I freeze this casserole?
A: Absolutely! Bake it, cool completely, then freeze slices in airtight containers. Reheat at 350°F for 20–25 minutes.
Q: Why is my casserole soggy?
A: Likely culprits: fresh bread (use stale/toasted!) or overloading add-ins. Next time, squeeze moisture from veggies and press bread into the custard.
Q: Can I use turkey sausage?
A: 100% yes! Just add a tablespoon of olive oil to the skillet since turkey’s leaner.
Q: How long does it keep in the fridge?
A: Up to 4 days! Reheat in the oven for best texture (microwave works in a pinch).
