Buttermilk French toast step-by-step
Here are the steps needed to make a successful buttermilk French toast. Full instructions are located in the recipe card.
In a shallow bowl, add the eggs, buttermilk, salt, vanilla, and cinnamon.
Whisk thoroughly to combine.
Dip the bread into the egg mixture, coating both sides. Do not let it get too saturated.

When the butter starts to sizzle, add the bread.
Cook until golden brown on one side. Flip and repeat on the other side.
📝Top tip for French toast success
Dip only one slice of bread at a time. That way you can control how saturated the bread gets. Don't forget to allow some of the excess egg mixture to drip off.
Substitutions and variations
- Buttermilk: Although there are numerous substitutions for buttermilk, I wouldn't go out of your way to make one here. The whole point is to use up that pesky leftover buttermilk. If you just want to make a delicious French toast, use milk or half and half in place of the buttermilk.
- Spices: You can customize the spices to suit your taste. Nutmeg, allspice, or even pumpkin pie spice can be used instead of or in addition to the cinnamon.
- Bread- Instead of sliced bread, get creative and use croissants, English muffins or even dinner rolls.
What to serve with French toast
Whether you are team maple syrup or team butter and maple syrup, here are a few more suggestions to make your French toast stand out.
- Maple syrup: This is a classic topping for French toast. Sweet and simple!
- Fresh fruit: Sliced strawberries, blueberries, bananas, raspberries, or any other favorite fruit can be a great addition.
- Whipped cream: A dollop of whipped cream can make your French toast feel more indulgent.
- Powdered sugar: One of my personal favorites.
- Nuts: Chopped nuts like almonds, pecans, or walnuts add some great texture.
- Yogurt: Top with Greek or flavored yogurt.
- Whipped butter: Flavored butter, like my sweet strawberry butter, is a perfect match.
- Compote or jam: Sweet and fruity jam, like this blueberry or strawberry one, is a match made in heaven. Try melting it slightly and pouring it like syrup.
Storage
French toast is best eaten right away, but you can store cooked French toast in the fridge for 3-4 days. To reheat, gently warm in the microwave or pan-fry on the stove until warmed through.
To freeze, simply place cooled slices on a baking sheet and place them in the freezer. Once frozen, you can remove them to a freezer-safe bag for easier storage. To reheat, place in the oven at 350°F for 8-10 minutes until heated through.
FAQ
When eggs are added to very cold buttermilk, you may see some curdling or thickening. Be sure to bring your buttermilk to room temperature, so that the eggs will dissolve when whisked.
A couple of things may contribute to soggy French toast. First, choose a good thick bread. Challah, brioche, Texas toast, or a thick white bread work best. If the bread is too thin, it will absorb all the buttermilk and egg custard too soon, causing your French toast to be soggy. Second, make sure you only coat each slice of bread in the buttermilk mixture at a time, allowing the excess to drip off. You want both sides of the bread to be wet, but not saturated.

OMG I will never make french toast another way! I have been making french toast for 25 years but when my daughter asked for it for breakfast this morning, I noticed that leftover buttermilk in the fridge and thought hmm.... I stumbled across your recipe and man, was it perfect! My kids devoured it! I've always used regular milk and it's so thin but the buttermilk created almost a custard to dip the bread in. It was incredible! The only thing I didn't have on hand was thick bread so I had to use white sandwich bread but I will be sure to get some and try this again soon!
