The Complete Shopping Rundown
- 8 slices bread, cubed — gotta pick one that soaks up the egg but don’t get soggy.
- 6 large eggs — the binder that makes everything come together, gotta be fresh.
- 2 cups milk — adds creaminess, don’t skimp here, whole milk works best.
- 1 cup shredded Gruyère cheese — cheese is key here, kinda nutty and melts so good.
- 1 cup cooked ham, diced — adds salty bites you’re gonna love all through the casserole.
- 4 tablespoons Dijon mustard — for a touch of zing, don’t be shy with this one.
- Salt to taste — just a pinch because ham’s salty already.
- Black pepper to taste — fresh ground is best for a little kick.
- 2 tablespoons butter, melted — this tops it off nice and golden on the crust.

Walking Through Every Single Move
- First, greasing your baking dish is important so nothing sticks and it’s easier to clean after.
- Then, preheat the oven to 350°F. This ain’t your pressure cooker part yet but gotta get the oven ready for the finish.
- In a big bowl, whisk together eggs, milk, Dijon mustard, salt, and pepper. This mix is the heartbeat of your casserole.
- Next, layer cubed bread evenly in the greased dish so every bite gets some egg and crust love.
- Sprinkle diced ham over the bread. Make sure it’s spread out so no spot is forgotten.
- Then toss on the shredded Gruyère cheese over the ham, that melted cheese gonna tie it all together.
- Pour the egg mixture slowly over the layered bread, ham, and cheese so everything soaks in good.
- Lastly, drizzle the melted butter on top for that golden crust. Bake for 30 mins until it’s set and brown. You can use your pressure cooker for steaming first if you want a quicker tender start before crisping.
Time Savers That Actually Work
- Use day-old bread so it soaks up egg better without falling apart.
- Grab pre-cooked ham from the deli, saves prep time and still fresh.
- Whisk eggs and milk in a big measuring cup to pour easy and mess-free.
- Prep your ingredients night before, so morning’s no rush at all.
- If you’re low on time, cook in pressure cooker with quick release to speed up the tender part, then finish in oven for crisp crust.

Your Leftover Strategy Guide
- Wrap leftovers tightly with plastic or foil then pop in the fridge for up to 3 days. It keeps moisture in and stops fridge smells sneaking in.
- For longer storage, freeze single portions in airtight containers. They thaw well in the fridge overnight, ready to reheat.
- Reheat in microwave covered with a damp paper towel or use your pressure cooker’s steam function to get that soft, moist texture back.
- If reheating in oven, cover with foil first to keep it from drying, then uncover at the end to crisp up the top layer again.
Your Most Asked Questions Answered
- Can I use other cheese besides Gruyère? Sure thing, Swiss or even mozzarella works but Gruyère melts and flavors best for this recipe.
- What bread is best? A slightly stale French bread or brioche cubes soak up the egg custard great without turning mushy.
- Can I prep this the night before? Absolutely! Assemble in your dish, cover well, and refrigerate overnight. Bake fresh in the morning.
- How do I know when it’s done? The casserole is set when the middle is firm and the edges are golden brown. A toothpick test works too, no wet spots means good.
- Can I skip the oven? You can do the pressure cooker part with slow release for tenderness but browning needs the oven or a broiler to get that crust.
- What if I don’t have Dijon mustard? Just use a little yellow mustard or skip it, but Dijon adds that little zing you gonna miss.
