The instant pot french toast casserole recipe below turns day-old bread and a simple egg custard into a soft, spoonable breakfast bake with almost no hands-on work. You get the comfort of a weekend brunch dish on a weekday timeline because the pressure cooker holds a steady temperature and steams the custard instead of baking it dry. This version uses pantry staples, a 7-inch round pan that fits most 6-quart pots, and a quick broil at the end for a lightly browned top.
A casserole cooked under pressure stays moist in the center while the edges set into a tender, pudding-like layer. You won’t stand at the stove flipping slices, and you won’t heat the oven for an hour. The method scales down well for small households and cleans up in one insert plus one pan. Making this instant pot french toast casserole at home is surprisingly straightforward once you know the key steps.
Why You’ll Love These Instant Pot French Toast Casserole
- Ready in about 25 minutes of active and cook time combined, not counting the optional broil.
- Uses stale bread you might otherwise toss, so less food waste and a firmer bite.
- One pan inside the pot means fewer dishes than a sheet-pan or skillet version.
- Custard stays evenly moist because steam surrounds the pan instead of drying from the top.
- Naturally customizable with fruit, spice, or syrup swaps without changing the core method.
Ingredients You’ll Need
- 6 cups cubed day-old brioche or French bread (about 1/2-inch pieces)
- 4 large eggs
- 1 1/2 cups whole milk
- 1/3 cup granulated sugar
- 2 tablespoons melted unsalted butter
- 1 teaspoon vanilla extract
- 1 teaspoon ground cinnamon
- 1/4 teaspoon salt
- 1/2 cup fresh blueberries
- 2 tablespoons maple syrup, plus more for serving
- 1 cup water, for the Instant Pot base
Ingredient Substitutions
Whole milk: Replace with an equal amount of half-and-half for a richer, thicker custard. Half-and-half has more fat, so the bake sets a little firmer and tastes closer to a restaurant-style bread pudding. You may notice slightly slower steam release because the denser liquid holds heat longer, but cook time stays the same. The instant pot french toast casserole works well for weeknight cooking when time is limited.
Brioche or French bread: Use an equal volume of fresh milled flour bread if that is what you have on hand. Fresh bread absorbs custard faster and can turn mushy, so let the cubes sit in the mixture only 5 minutes before cooking rather than 10. Expect a softer, less structured bite and a slightly nutty flavor from the whole grain. Storing leftover instant pot french toast casserole correctly keeps it tasting good for days.
Blueberries: Swap with an equal measure of diced apples tossed in the cinnamon for a fall-style bake. Apples release less moisture than berries, so the custard stays thicker and the top browns a touch faster under the broiler. Cut pieces small so they soften fully during the short pressure time. For the best results with this instant pot french toast casserole, read through all the steps before starting.
Granulated sugar: Use an equal weight of brown sugar for deeper molasses notes and a darker finished top. Brown sugar draws a little more moisture, so the center may read as looser; add 1 extra tablespoon of bread cubes to balance it. The flavor shifts from clean sweet to caramel-like without any other change.
Step-by-Step Instructions
- Grease a 7-inch round metal pan with butter. Place the cubed bread in the pan and spread evenly so the custard can reach all pieces.
- Whisk the eggs, whole milk, granulated sugar, melted butter, vanilla, cinnamon, and salt in a bowl until smooth and no streaks remain.
- Pour the custard over the bread. Press the bread down gently so every cube is coated, then let it rest for 10 minutes at room temperature.
- Stir the blueberries and maple syrup into the soaked bread, distributing them without compacting the cubes too tightly.
- Pour 1 cup water into the Instant Pot liner. Set the trivet inside, then lower the pan onto it using a foil sling.
- Lock the lid, set valve to sealing, and cook on high pressure for 25 minutes until the center reaches just set edges with a slight jiggle.
- Let pressure release naturally for 10 minutes, then quick-release the rest. Lift the pan out and blot any condensation from the top with a paper towel.
- For a browned top, broil the pan 3 minutes on a middle rack until golden and crispy at the edges. Cool 5 minutes before slicing.
Pro Tips
Cut bread into uniform 1/2-inch cubes so the custard penetrates evenly and no large dry centers remain after pressure cooking. If pieces vary too much, the big ones stay tough while small ones turn to paste.
Use a foil sling made from a 20-inch strip folded twice so you can lower and lift the pan without tipping the raw custard. This prevents burns and keeps the layer level for even cooking.
Always let the sealed pot sit the full 10 minutes of natural release or the custard can collapse and weep liquid when you open it. A sudden drop in pressure pulls moisture out of the set eggs.
Check doneness by tapping the pan; it should feel firm at the rim and move as one piece, not slosh. For more on gentle heat control, see cooking techniques from Food Network.
Common Mistakes to Avoid
Using fresh soft bread without rest time leads to a soggy mass because it soaks too fast and loses shape under steam. Stick to day-old or lightly toasted cubes and the 10 minutes soak.
Skipping the trivet and water puts the pan directly on the hot base, where the bottom scorches before the center sets. The steam layer under the pan is what cooks it gently from all sides.
Opening the lid right after cook time without the natural release lets the custard sink and separate. The 10 minutes hold finishes the set off heat.
Serving Suggestions
Spoon the bake onto plates and pour warm maple syrup across the top for a classic sweet finish. A side of greek salad adds a crisp, acidic contrast that keeps the meal from feeling too heavy.
For brunch, pair with peach lemonade or hot coffee and a dusting of powdered sugar. The casserole also works as a base under sauteed apples if you want more fruit.
Storage and Reheating
Cool the casserole fully, then cover the pan or move slices to an airtight container and refrigerate for up to 3 days. Cooked egg custard should not sit out more than 2 hours total before chilling.
Reheat individual portions in a 350°F oven for 10 minutes or microwave 1 minute until steaming throughout. The dish does not freeze well because the custard weeps when thawed, so plan to eat it fresh from the fridge.
Recipe Variations
Berry Citrus Version
Replace blueberries with raspberries and add 1 teaspoon orange zest to the custard. The citrus brightens the sweet base and the softer berries melt into pockets, giving a tangier, lighter result than the plain bake.
Classic Stovetop Style
If you prefer sliced bread, follow the custard from this french toast method on the stove instead of the pot. You lose the hands-off casserole format but get a firmer, seared exterior with the same flavor profile.
Protein Boost Bake
Mix 1/2 cup cottage cheese into the custard before pouring for added body and a slightly savory note. This shifts the texture toward a crustless quiche and pairs well with the high protein casserole approach if you meal prep breakfasts.
Savory Herb Option
Drop the sugar and cinnamon, add 1/2 teaspoon dried thyme and 1/4 cup shredded cheese on top before broiling. The result is a breakfast strata-like dish that skips syrup and works with focaccia on the side.

Ingredients
Instructions
-
Grease and fill pan
Grease a 7-inch round metal pan with butter to prevent sticking. Place the cubed bread in the pan and spread it evenly so the custard can reach all pieces and cook uniformly.
-
Whisk custard mixture
Whisk the eggs, whole milk, granulated sugar, melted butter, vanilla, cinnamon, and salt in a bowl until smooth and no streaks remain. This creates a uniform custard that will coat the bread without clumps of spice or sugar.
-
Soak bread cubes
Pour the custard over the bread and press the bread down gently so every cube is coated. Let it rest for 10 minutes at room temperature so the day-old cubes absorb the liquid and soften at the edges.
-
Add fruit and syrup
Stir the blueberries and maple syrup into the soaked bread, distributing them without compacting the cubes too tightly. This keeps the bake airy while adding pockets of fruit and sweetness throughout.
-
Set up Instant Pot
Pour 1 cup water into the Instant Pot liner to create the steam base. Set the trivet inside, then lower the pan onto it using a foil sling so the pan stays level above the water.
-
Pressure cook casserole
Lock the lid, set valve to sealing, and cook on high pressure for 25 minutes until the center reaches just-set edges with a slight jiggle. The custard should feel firm at the rim and move as one piece when you tap the pan, not slosh.
-
Release and uncover
Let pressure release naturally for 10 minutes, then quick-release the rest to avoid collapsing the custard. Lift the pan out with the sling and blot any condensation from the top with a paper towel so the surface stays dry for broiling.
-
Broil and cool
For a browned top, broil the pan 3 minutes on a middle rack until golden and crispy at the edges. Cool 5 minutes before slicing so the set custard firms enough to lift clean portions from the pan.
