15 Cinnamon Roll French Toast Casseroles

A cinnamon roll french toast casserole takes everything good about a lazy Sunday breakfast and bakes it into one dish. Tinned cinnamon rolls are torn into pieces, soaked in a sweet egg custard overnight, then baked until puffed and golden, so all the fiddly dipping-and-frying of regular french toast is done for you. It's the kind of recipe that feeds a crowd off one tin of dough and a handful of storecupboard staples, and it always looks far more impressive than the effort it actually takes. Below are 15 ways to make it, plus the tips you need to get a custardy middle and a crisp, glazed top every time.

This is the version to start with: two tins of refrigerated cinnamon rolls, cut into quarters, tossed into a buttered dish and covered in a simple custard of eggs, milk and vanilla. The reserved icing from the tins is warmed slightly and drizzled over the top once the bake comes out of the oven, so it melts into every crevice. Give it a full 30 minutes at 175°C (350°F) so the centre sets without the edges drying out. It's the benchmark recipe every other variation on this list is riffing on.

For the fewest steps possible, skip cutting the rolls into small pieces and just quarter them roughly, then pour the custard straight over without whisking it separately in a bowl first. Use a single 240 ml (1 cup) measuring jug to mix the eggs and milk directly, which cuts down on washing up. This version leans on pre-made icing and a shop-bought cinnamon-sugar mix rather than anything homemade, so it's genuinely a 10-minute-prep bake. It's the one to reach for on a busy weekday when you still want a warm, sweet breakfast on the table.

Add warmth with extra ground cinnamon, a pinch of nutmeg and a splash of maple syrup stirred straight into the custard rather than just poured on afterwards. A layer of brown sugar and a knob of butter scattered over the top before baking helps form a slightly crisp, caramelised crust. This is the version for cold mornings, best served straight from the oven while it's still steaming. Pair it with a hot coffee and it does most of the comfort-food work on its own.

Strip the recipe back to just cinnamon rolls, eggs, milk and a spoon of vanilla, skipping any extra sugar since the rolls already bring plenty of sweetness. This keeps the bake from tipping into overly sweet territory, which matters if you're serving it alongside fruit or savoury sides like bacon. Bake uncovered at 175°C (350°F) for 25-30 minutes until just set in the centre. It's a good base recipe to adapt once you know how much extra sweetness or spice your household actually wants.

Swap half the milk for double cream (heavy cream) or use full-fat half-and-half to make the custard noticeably richer, and let the dish soak for at least 20 minutes before it goes in the oven so the cream has time to soften the dough right through. Cubes of cream cheese, about 115 g (4 oz), tucked between the cinnamon roll pieces melt into pockets of tang that balance the sweetness. The result is closer to a bread pudding than a dry bake, with a soft, almost custardy interior. Serve it warm with a spoon rather than a fork, since the middle stays wonderfully loose.

Pile on the extras here: chopped pecans, mini chocolate chips, a swirl of caramel sauce and a scattering of extra cinnamon-sugar all go over the top before baking. Add the nuts and chocolate about two-thirds of the way through cooking if you want them to stay slightly crisp rather than fully melting in. This is the showstopper version for a birthday brunch or a holiday morning when more toppings genuinely make it better. Finish with the reserved icing plus an extra drizzle of caramel once it's out of the oven.

This version combines the best tricks from the others: an overnight soak, a custard enriched with a splash of cream, a layer of brown sugar and butter for a crisp top, and a cream cheese glaze made by beating the reserved icing with 60 g (2 oz) of softened cream cheese and a little milk. Letting it rest overnight in the fridge is the single biggest factor in getting a bake that's custardy in the middle instead of dry. Bake it covered with foil for the first 15 minutes, then uncovered for the remainder so the top browns properly. It takes a little more planning than the others, but it's worth it for special occasions.

This one sounds unusual but works: a light scattering of mascarpone or cream cheese folded through the custard adds richness without making the dish taste savoury. Keep it to small dollops rather than a full layer, so you still taste mostly cinnamon and vanilla rather than cheese. It's a good option if you find standard versions a bit too sweet, since the cheese cuts through the sugar. Bake as normal and finish with a light dusting of icing sugar instead of a full glaze to keep the balance right.

Stretch a single tin of cinnamon rolls further by bulking the dish out with cubed day-old white bread or brioche ends, using roughly equal parts bread and cinnamon roll pieces. The custard and cinnamon-sugar flavour the plain bread so it tastes just as indulgent, while the tin of rolls still provides that signature swirl and icing. This is the version to make when you're feeding a crowd but only have one tube of dough in the fridge. It costs a fraction of the multi-tin versions and nobody will notice the difference once it's baked and glazed.

Scale up to three tins of cinnamon rolls and a 33 x 23 cm (13 x 9 in) dish, doubling the custard to roughly 8 eggs and 480 ml (2 cups) of milk so every piece is properly coated. Bake for closer to 35-40 minutes given the larger volume, checking that a knife inserted in the centre comes out clean. This version is built for holiday mornings, potlucks or any time you're feeding more than eight people. Keep the icing separate until serving time so it stays glossy rather than soaking in while the dish waits on the table.

Assemble the whole dish the night before, right up to pouring over the custard, then cover tightly with cling film and refrigerate for 8-12 hours before baking. Take it out of the fridge about 20 minutes before it goes in the oven so it isn't ice-cold, which can mean it needs an extra 5-10 minutes of baking time to set properly in the centre. This is the version built for Christmas morning or houseguests, since all the work happens the evening before. Wait to add the icing drizzle until just before serving so it doesn't turn cloudy or dry out overnight.

Keep this version simple and mild for younger palates: dial back any extra spice, skip nuts or anything with a bite, and use a lightly sweetened custard so the tinned icing does most of the sweet work. Cut the baked casserole into individual squares before serving, which makes portioning for kids far easier than scooping from the dish. A side of sliced banana or berries rounds it out without adding more sugar. It reheats well too, so leftover squares make an easy grab-and-go breakfast for school mornings.

Stir in 120 g (1/2 cup) of pumpkin purée and a teaspoon of mixed spice for an autumn version, or fold through 150 g (1 cup) of fresh or frozen cranberries and orange zest for a Christmas-morning take. Both additions go straight into the custard so the flavour runs through the whole bake, not just the top. A finishing dust of icing sugar and a few extra cranberries or a cinnamon stick make it look properly seasonal on the table. This is the one to swap in for pancakes on the big holiday mornings when you want something that can be prepped the night before.

For mornings with no overnight soak time, use a hot custard: warm the milk gently before whisking in the eggs, which helps it soak into the dough faster. Cut the cinnamon roll pieces smaller than usual, about 2.5 cm (1 in), so they absorb the custard within 10 minutes rather than needing hours. Bake at a slightly higher 190°C (375°F) for 20-22 minutes to compensate for the shorter soak. It won't be quite as custardy as the overnight versions, but it gets a warm, glazed bake on the table in well under an hour.

Skip the tinned dough entirely and make a simple enriched cinnamon roll dough from scratch, roll and cut it, then let the individual rolls prove before tearing them into pieces for the bake. It takes considerably longer, closer to 3 hours including proving time, but gives a lighter, more brioche-like texture than tinned dough. Make your own glaze too, whisking 100 g (3/4 cup) icing sugar with a tablespoon of milk and a little vanilla. This is the weekend project version for when you want full control over the dough and the sweetness.

Let the assembled dish sit for at least 20-30 minutes before baking, even if you're not doing a full overnight soak, so the custard has time to soak into the dough rather than pooling at the bottom. Check for doneness with a knife inserted near the centre; it should come out clean or with just a few moist crumbs, not wet batter. If the top is browning too fast before the centre sets, loosely tent it with foil for the last 10 minutes. Always use cold eggs and milk if soaking overnight, but bring the dish closer to room temperature before it goes in a hot oven so it bakes evenly.

Serve warm, ideally within 15 minutes of coming out of the oven, with the reserved icing or a cream cheese glaze drizzled over just before it hits the table. A side of crispy bacon or breakfast sausage balances the sweetness nicely, and fresh berries or sliced banana add a bit of freshness. For a proper brunch spread, add a pot of coffee and a jug of maple syrup on the side so everyone can adjust to taste. Leftover squares also work well folded into a packed lunch or eaten cold as a sweet snack.

Store leftovers covered in the fridge for up to 3-4 days once fully cooled. Reheat individual portions in the microwave for 30-45 seconds, or warm a larger amount in the oven at 160°C (325°F) covered with foil for 10-15 minutes to stop it drying out. To freeze, bake and cool completely, then wrap tightly in cling film and foil for up to 2 months, thawing overnight in the fridge before reheating. Hold off adding fresh icing or glaze until after reheating, since it can turn watery if frozen or chilled with the casserole.
