This Strawberry French Toast Casserole is everything you want on a slow weekend morning, sweet, golden, and smelling like vanilla from the moment it goes into the oven.
Fresh strawberries soak into pillowy challah bread overnight (or in just a few minutes if you’re pressed for time), and the whole thing bakes up into something that looks like you spent hours on it.
Spoiler: you didn’t.
The custard is simple, eggs, whole milk, a splash of half and half, brown sugar, vanilla, and a pinch of cinnamon.
That’s really all it takes to turn a loaf of bread and a pint of berries into the prettiest dish on the brunch table.
It’s a make-ahead dream, great for feeding a crowd, and genuinely one of those recipes people ask about long after the meal is over.

Recommended Products for This Recipe
These are a few products I genuinely reach for when making this casserole, they make the process easier and the results better.
1. Le Creuset Stoneware Baking Dish
This dish distributes heat so evenly that your casserole bakes through perfectly without any dry edges or soggy center.
The glazed interior also makes it much easier to serve and clean up. It’s worth every penny if you bake often.
2. Nielsen-Massey Madagascar Bourbon Pure Vanilla Extract
The custard in this recipe only has a handful of ingredients, so the quality of your vanilla extract really matters.
This one has a deep, floral flavor that makes the custard taste noticeably richer. A little goes a long way.
3. OXO Good Grips 3-Piece Mixing Bowl Set
Having a large enough mixing bowl makes whisking the custard so much easier, you need room to really whip those eggs and milk together.
This set is durable, easy to clean, and the non-slip base keeps everything stable on the counter.
4. Microplane Spice Grater (for fresh cinnamon)
If you want to use a whole cinnamon stick and grate it fresh, this microplane makes it effortless.
Freshly grated cinnamon has a more vibrant, complex flavor than pre-ground, and it’s a small upgrade that makes a real difference in the custard.
Step-by-Step Instructions: How to Make Strawberry French Toast Casserole
1. Prepare Your Baking Dish and Bread
- Preheat your oven to 350°F (175°C). Set the rack to the middle position so the casserole bakes evenly from top to bottom.
- Lightly grease your 9×13-inch baking dish with cooking spray or a thin layer of softened butter. Make sure you coat the sides too, not just the bottom.
- Take your challah loaf and cut it into roughly 1-inch cubes. You don’t need to be perfectly precise — uneven pieces actually give the finished casserole more texture. You should end up with about 10 to 12 cups of cubed bread.
- If your challah is very fresh and soft, you can use it as-is. If it’s slightly stale (1 to 2 days old), even better — drier bread soaks up the custard more effectively without becoming mushy.
- Spread the bread cubes evenly across the prepared baking dish, filling it in a single loose layer. It’s okay if the cubes pile up slightly — they will compress as the custard soaks in.
2. Prepare the Fresh Strawberries
- Rinse your strawberries under cold water and pat them dry with paper towels. Wet berries can dilute the custard, so take a moment to dry them well.
- Remove the green tops (hulling) by cutting off a thin slice from the top of each berry with a sharp paring knife. You can also use a strawberry huller if you have one.
- Slice the strawberries into roughly ¼-inch-thick rounds or halves, depending on the size of your berries. Smaller berries can be halved; larger ones slice nicely into coins.
- Scatter the sliced strawberries evenly over the bread cubes in the baking dish. Try to tuck some pieces in between the bread cubes so berries end up throughout the casserole, not just on top.
- Gently press a few pieces of bread down around the strawberries so everything sits together snugly in the pan.
3. Make the Custard Mixture
- Crack all 6 eggs into your large mixing bowl. Check for any shell fragments and remove them if needed.
- Add the 1¾ cups whole milk and ½ cup half and half to the bowl with the eggs. Whole milk gives the custard body and richness, while the half and half adds extra creaminess.
- Add the ¼ cup of packed brown sugar. Brown sugar gives a slightly caramel-like sweetness that white sugar doesn’t quite replicate.
- Pour in the 1½ teaspoons of vanilla extract and sprinkle in the ½ teaspoon of cinnamon.
- Whisk everything together vigorously for about 60 seconds until the mixture is smooth, the sugar has dissolved, and you see a slight foam on top. There should be no streaks of egg white remaining.
- Taste the custard at this point — it should smell fragrant and taste lightly sweet. You can add a tiny pinch more cinnamon if you want a stronger spice flavor.
4. Pour the Custard Over the Bread
- Slowly and evenly pour the custard mixture over the bread and strawberry mixture in the baking dish. Pour it in a back-and-forth motion across the pan so every area gets covered.
- Once all the custard is poured in, use the back of a spoon or your hands (clean, of course) to gently press the bread cubes down into the custard. You want the bread to start absorbing the liquid right away.
- Make sure no bread cubes are sitting completely on top, dry and untouched. Every piece should have some custard contact.
- At this point, you have two options: bake immediately or soak overnight.
- For the overnight method: Cover the dish tightly with plastic wrap and refrigerate for at least 4 hours, or ideally overnight. This gives the bread maximum time to soak up all the custard, resulting in a richer, more cohesive casserole.
- For the quick method: Let the assembled casserole sit uncovered at room temperature for 20 to 30 minutes before baking. This gives the bread enough time to absorb the custard and ensures an even bake.
5. Bake the Casserole
- If you refrigerated the casserole overnight, remove it from the fridge and let it sit on the counter for 15 to 20 minutes before baking. This takes the chill off the dish and helps it bake more evenly.
- Place the baking dish on the middle rack of your preheated 350°F oven.
- Bake uncovered for 45 to 50 minutes. The casserole is done when the top is golden brown, the custard is set (no longer jiggly in the center), and the edges are just beginning to pull away from the sides of the pan.
- If the top is getting too golden before the center is set, loosely tent the dish with a piece of aluminum foil for the last 10 minutes of baking. Remove the foil for the final 5 minutes to crisp back up the top.
- To check for doneness, insert a knife or toothpick into the center of the casserole. It should come out clean, with no wet custard clinging to it.
- Remove from the oven and let the casserole rest for 10 minutes before serving. This allows it to set fully so it slices and scoops cleanly.

Tips for The Best Strawberry French Toast Casserole
A few small details really do make a big difference with this casserole. The most important one: use day-old challah if you can.
Slightly dried-out bread absorbs the custard much better than super-fresh bread, which can turn soggy instead of custardy.
- Use day-old challah. Fresh bread is too moist. Letting it sit out uncovered for a few hours (or overnight) firms it up and lets it soak the custard without turning mushy.
- Don’t skip the rest before baking. Even the quick 20-minute room-temperature soak makes a noticeable difference in texture.
- Pack the brown sugar. Loosely measured brown sugar will give you less sweetness than the recipe intends. Pack it firmly into the measuring cup.
- Use whole milk, not low-fat. The fat in whole milk is what gives the custard its creamy, rich texture. Low-fat milk will produce a thinner, less satisfying result.
- Add toppings before baking. A light sprinkle of extra brown sugar over the top before it goes in the oven creates a beautiful caramelized crust.
- Don’t overbake. Pull it out as soon as the center is set. Overbaking dries out the custard and makes the strawberries taste less fresh.
- Tent with foil if needed. If the top is browning too fast, a loose foil tent for the last 10 minutes keeps it from getting too dark while the center finishes cooking.
Serving Suggestions
This casserole is a complete showstopper on its own, but a few simple additions can make it feel even more special at the table.
A drizzle of warm maple syrup and a dusting of powdered sugar are the classic finishing touches, but fresh whipped cream takes it completely over the top.
- Serve warm with a generous dusting of powdered sugar and a drizzle of maple syrup
- Add a dollop of lightly sweetened whipped cream or a scoop of vanilla ice cream for dessert-level indulgence
- Fresh sliced strawberries on top right before serving brightens everything up and makes it look stunning
- Pair it with crispy bacon or breakfast sausage to balance the sweetness with something savory
- Serve alongside a glass of fresh-squeezed orange juice or a tall pitcher of Strawberry Basil Lemonade for the ultimate brunch spread
- A Fruit and Yogurt Parfait makes a refreshing, lighter side that pairs beautifully with the richness of the casserole
Variations of Strawberry French Toast Casserole
Once you’ve made this once, you’ll want to riff on it. The base recipe is incredibly flexible, and a few swaps can make it feel like a brand-new dish every time.
- Mixed Berry Casserole: Swap out some or all of the strawberries for blueberries, raspberries, or blackberries. A mixed berry version is especially colorful and beautiful.
- Strawberry Cream Cheese Version: Drop small spoonfuls of softened cream cheese (sweetened with a little sugar and vanilla) between the bread cubes before pouring over the custard. It creates little pockets of richness throughout.
- Nutella Swirl: Warm a few tablespoons of Nutella until pourable and drizzle it over the assembled casserole before baking for a chocolate-strawberry twist.
- Brioche Bread Swap: Can’t find challah? Brioche works just as well and gives a similarly rich, buttery result. Regular French bread works in a pinch but produces a slightly less custardy texture.
- Lemon Zest Addition: Add the zest of one lemon to the custard mixture for a bright, citrusy note that works beautifully with fresh strawberries.
- Streusel Topping: Mix together 3 tablespoons each of flour, brown sugar, and cold butter until crumbly, then sprinkle it over the top before baking for a crisp, crumble-like crust.

Storage and Reheating
This casserole stores well and reheats beautifully, which makes it perfect for making ahead of a busy morning.
It keeps its texture better than most egg-based bakes, especially when stored and reheated properly.
- Refrigerator: Cover leftover casserole tightly with plastic wrap or transfer to an airtight container. Store in the fridge for up to 3 days.
- Freezer: Cut the cooled casserole into individual portions, wrap each piece tightly in plastic wrap, and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
- Oven reheating (best method): Cover the casserole loosely with foil and reheat in a 325°F oven for 15 to 20 minutes until heated through. This keeps the texture close to freshly baked.
- Microwave reheating: Individual portions can be microwaved on medium power for 60 to 90 seconds. Cover with a damp paper towel to prevent drying out.
- Do not refreeze once thawed. Refreeze only if the casserole was originally frozen before baking.

Health Benefits of Key Ingredients
This is a treat, no question, but the ingredients in this casserole bring some real nutritional value to the table alongside the indulgence.
From fiber-rich berries to protein-packed eggs, there’s more going on here than just great flavor.
- Strawberries are loaded with vitamin C, manganese, and antioxidants. They’re also a good source of dietary fiber, which supports digestive health.
- Eggs are one of the most complete sources of protein available. They also provide choline, which is important for brain health, and essential fat-soluble vitamins including A, D, E, and K.
- Whole milk provides calcium and vitamin D, both of which are crucial for bone health. It also contains high-quality protein and healthy fats that help you feel satisfied.
- Challah bread contains eggs and oil in the dough, which gives it a slightly higher protein and fat content than plain white bread. It also provides carbohydrates for sustained energy.
- Cinnamon has well-documented anti-inflammatory properties and may help support healthy blood sugar levels when consumed regularly as part of a balanced diet.
- Brown sugar contains trace amounts of minerals like calcium, potassium, and iron, unlike white sugar which is completely stripped of these during processing.

FAQs About Strawberry French Toast Casserole
1. Can I use frozen strawberries instead of fresh?
You can, but fresh strawberries give far better results. Frozen berries release a lot of liquid as they thaw, which can make the casserole soggy and dilute the custard.
If frozen is all you have, thaw them completely first, drain off the excess liquid, and pat them dry before using.
2. Can I assemble this casserole the night before?
Absolutely. That’s actually the recommended method. Assembling the night before and refrigerating gives the challah plenty of time to absorb all the custard, resulting in a much richer and more cohesive bake.
Just remember to take it out of the fridge 15 to 20 minutes before baking so it’s not stone cold when it goes into the oven.
3. What can I use instead of challah bread?
Brioche is the best substitute, it has a similar richness and egg-enriched texture that works beautifully for French toast casseroles.
Texas toast or thick-cut French bread are decent alternatives, though the result will be slightly less rich.
Avoid thin sandwich bread, as it tends to break down completely and turn the casserole paste-like instead of custardy.
4. How do I know when the casserole is done baking?
The casserole is done when the top is golden brown and the center no longer jiggles when you gently shake the pan.
A knife inserted into the center should come out clean with no wet custard.
The internal temperature should reach around 160°F if you want to be precise — a simple instant-read thermometer makes this check very easy.
5. Can I add a topping before baking?
Yes, and it’s highly recommended. A simple sprinkle of brown sugar over the top before baking creates a gorgeous, lightly caramelized crust.
You can also make a quick streusel by mixing equal parts flour, brown sugar, and cold butter until crumbly and scattering it over the top, it bakes up into a beautiful crisp layer that contrasts perfectly with the soft custard beneath.

Notes
- Use day-old challah: Slightly stale bread absorbs the custard much better than fresh, resulting in a richer, custardy texture rather than a soggy one.
- Overnight soak: Assembling the night before and refrigerating is the recommended method — it produces a noticeably more cohesive, flavorful casserole. Take it out of the fridge 15–20 minutes before baking.
- Bread substitution: Brioche is the best swap for challah. Texas toast or thick-cut French bread work in a pinch, but avoid thin sandwich bread.
- Frozen strawberries: If using frozen, thaw completely, drain all excess liquid, and pat dry before using to prevent a watery casserole.
- Add a crisp topping: Sprinkle extra brown sugar over the top before baking for a caramelized crust, or mix equal parts flour, brown sugar, and cold butter for a quick streusel topping.
- Check for doneness: A knife inserted into the center should come out clean, or an instant-read thermometer should read 160°F. Tent loosely with foil during the last 10 minutes if the top browns too quickly.
- Storage: Cover and refrigerate leftovers for up to 3 days. Reheat covered in a 325°F oven for 15–20 minutes, or microwave individual portions on medium power for 60–90 seconds.
- Freezing: Slice cooled leftovers into portions, wrap tightly in plastic wrap, and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
- Cream cheese variation: Drop small spoonfuls of sweetened cream cheese between the bread cubes before adding the custard for rich, creamy pockets throughout the casserole.
- Lemon zest upgrade: Add the zest of one lemon to the custard for a bright citrusy note that pairs beautifully with the fresh strawberries.
