Most breakfast casseroles fail because they're either too wet, too dry, or under-seasoned.
This one works because:
- vegetables are cooked first (no watery casserole)
- bread is stale (absorbs custard properly)
- custard is seasoned (not bland)
- it rests before baking (even texture)
It's simple, forgiving, and perfect for holidays like Easter brunch.
Ingredients
Base
6 cups chopped vegetables
(onion, peppers, mushrooms, asparagus — whatever you have)
butter
Lucky Cajun Black Label seasoning
Optional Add-Ins
bacon
ham
smoked salmon
Bread Layer
6 cups stale baguette or white bread, cubed
Custard
12 eggs
3 tablespoons Dijon mustard
¼ cup sour cream
1 tablespoon Lucky Cajun Black Label seasoning
1 cup milk
1 cup heavy cream
Cheese
any cheese you have on hand (shredded)
Instructions
Step 1 – Cook the Vegetables
In a large pan, melt butter and cook your chopped vegetables until softened.
Season with Lucky Cajun Black Label.
You're looking for cooked and flavorful — not raw, not watery.
If using bacon or ham, cook and add it here.
Step 2 – Build the Custard
In a large bowl whisk together:
eggs
Dijon mustard
sour cream
Lucky Cajun Black Label
Once smooth, whisk in:
milk
heavy cream
Step 3 – Assemble
In a casserole dish, layer:
bread
vegetables
cheese
Repeat if needed.
Pour the custard evenly over the top.
Press everything down lightly so the bread absorbs the liquid.
Let it sit for 30 minutes so the custard soaks in.
Top with more cheese.
Step 4 – Bake
Bake at 350°F:
30 minutes covered
Then uncover and bake another 15–20 minutes until set and golden.
If using a deeper casserole dish, add a few extra minutes as needed.
Step 5 – Rest (Don't Skip This)
Let the casserole rest for 15 minutes before slicing.
This is what sets the structure and keeps it from falling apart.

It's built to adapt.
Common Mistakes (And Fixes)
Why is my casserole watery?
Vegetables weren't cooked first. Always cook them down before assembling.
Why is the center undercooked?
The casserole didn't rest long enough before baking or wasn't baked long enough.
Can I make this ahead of time?
Yes. Assemble it the night before, refrigerate, and bake the next day.
