What to Do With Leftover French Toast Batter

One of my favorite memories from childhood is my dad making French toast. We didn’t eat it for breakfast; instead, we had breakfast for dinner.

None of us ever wanted to get up that early. Dad always got Texas toast from the day-old bread store to use in our French toast.

He’d serve it up with a sprinkle of powdered sugar, a dollop of whipped cream, some berries, and a side of bacon. Mmmm . . . that meal may not have been especially healthy, but it sure did taste good.

Dad cooked French toast until the bread and the custard mix were gone. Any leftover toast was breakfast the next day. 

Sometimes though, you may not have your custard mixture to bread ratio quite right, and you end up with leftover French toast batter.

We’ve rounded up some ideas for what you can do with the leftover batter rather than throwing it out.

You can store French toast batter in the fridge for up to 24 hours and use it the next day. You can make extra French toast slices and freeze them for a quick breakfast later.

Try making a sweet and savory Calvados omelet. Add the leftover custard mix to your ice cream base for French Toast ice cream. If you are out of bread, dip flour tortillas in it and make fake, but delicious, crepes.

Use some canned biscuit dough and make French toast monkey bread or other stale bread for French toast bread pudding.

You can also make some extra toast with a little less batter and use it for sandwiches with Nutella or fruit.

French Toast Batter Recipe

French toast batter or custard is a basic mix of eggs, milk, sugar, and cinnamon.

You can find many different ratios and add-ins for jazzing up your French toast and making it your own. Try this basic recipe:

  • 4 large eggs
  • 2/3 cup milk (or cream)
  • ¼ – ½  cup granulated sugar
  • 1/4 teaspoon salt
  • 1 teaspoon ground cinnamon
  • 1 -2 teaspoon vanilla extract (feeling brave? Use a tablespoon of good quality real vanilla)

Other popular add-ins for your French toast are nutmeg, brown sugar, flavored coffee creamer (we love salted caramel), or two tablespoons of Grand Marnier orange liqueur.

You can also use half-and-half or heavy cream instead of milk for a richer flavor. 

One trick to making the custard creamy and not eggy is to blend it thoroughly so the egg is smooth. One option is to run it through the blender to really break up the egg whites.

Another option is to use 6 egg yolks instead of 4 whole eggs. The yolks are creamier and stay blended with the milk or cream better.

Use the egg whites to make an egg-white omelet to eat with your French toast.

What Kinds of Bread Make Good French Toast?

Everyone has their favorite bread for making French toast. In general, you will want to use slightly stale bread that is cut into thick slices. Beyond that, the choice is yours.

Challa and brioche make nice french toast because they are lighter and fluffier than sandwich bread.

King’s Hawaiian Bread with its slightly sweet taste makes amazing French toast.

Stale white bread like Texas toast or Sara Lee White Artesano Bread are also excellent candidates. 

However, you should think outside the box. Use the last 2 slices of raisin bread in the bag or the leftover hamburger buns from the cookout.

I’ve actually had cinnamon rolls sliced so you can see the spiral battered and fried like french toast. (It was amazing – I didn’t eat for the rest of the day.) 

What’s the Difference Between Eggy Bread and French Toast?

Eggy bread and French bread are made by the same process, but the batter is different.

French toast is sweetened with sugar and also has cinnamon and vanilla. Eggy bread is savory with just eggs, milk, and butter. 

What to do With Leftover French Toast Batter

When you have leftover French toast batter, store it in an airtight container in the refrigerator and use it within 24 hours. You should whisk it thoroughly before using it again to make sure that the eggs are well incorporated.

Unfortunately, the batter mixture doesn’t freeze well.  If you won’t use the leftover batter the next day, your best bet is to make extra toast and freeze the cooked French toast as individual portions.

1. Refrigerate French Toast Egg Mixture Overnight and Make More French Toast the Next Day

What goes best with French toast? More French toast! Okay, maybe you need a short break between helpings. You can put the leftover batter in an airtight container and store it in the fridge for up to 24 hours.

You should use it or discard it within a day because as you dip bread in it, you have been introducing bacteria to the mix.

Give it a good whisk the next morning and have a couple of extra slices of toast before the mixture is all gone. 

2. Refrigerate Leftover Cooked French Toast

You have fed the whole family, and you have both French toast batter and a few slices of bread left. Go ahead and dip the toast and cook it.

Store leftover slices of French toast in an airtight container in the refrigerator for up to 48 hours. 

3. Freeze Leftover Cooked French Toast

Alternatively, freeze the slices individually for up to 3 months. They are easy to reheat in the microwave, toaster oven, or skillet in just a few minutes. you need to cook the toast before freezing it.

Trying to freeze dipped but unfrozen toast will most likely result in mush rather than toast when you reheat it later.

How to Properly Freeze French Toast

  • Cook the French toast.
  • Lay it out in a single layer on a parchment paper-lined baking sheet.
  • Place the whole baking sheet in the freezer and leave them until they are frozen hard (at least 2 hours).
  • Then, wrap the slices 2 at a time in parchment paper. 
  • Place the wrapped toast in a large zip-top bag or airtight container.
  • Store the toast for three months in the freezer.

4. Calvados Omelet

American Chef Gabrielle Hamilton uses the last bit of French toast batter to make a fascinating omelet. Take your leftover batter and whisk in a sprinkle of flour.

You may also want to add an additional egg or egg yolk if your batter is especially milky. Measure out 2 tablespoons of Calvados brandy, 2 tablespoons of butter, and 1 teaspoon of sugar.

Instructions

  1. Heat 1 tablespoon of butter in a nonstick skillet until the butter starts to foam. Pour in 2 – 3 ounces of batter and let it set for a moment without stirring it. 
  2. Use a rubber spatula to gently pull the mixture from the edges toward the center until all the batter has run into the pan and cooked. 
  3. When the omelet is golden brown on the bottom, flip it over. 
  4.  Pour in a tablespoon of room-temperature Calvados and light the alcohol. Remove the pan from the stove and let the flame burn out.
  5. Slide the omelet onto a plate, spread with butter, and sprinkle with sugar. 

5. French Toast Ice Cream

Homemade ice cream is a fantastic treat any time of year. You can use your leftover French toast custard base with a creamy ice cream custard base and make French toast ice cream.

  3. Reduce heat to low; continue cooking for 2 more minutes then remove from heat.
  4. Whisk the eggs (or just egg yolks) and leftover French toast batter in a small bowl. Quickly whisk in ½ -⅓ cup of the hot cream mixture. Whisk constantly so the eggs will heat up without curdling. 
  5. Return everything to that large saucepan and whisk vigorously for 2 more minutes.
  6. Pour the mixture into a large bowl and place it in a pan filled with ice water. Stir gently for 2 minutes. Place plastic wrap on top of the custard so that no air reaches the mixture.
  7. Refrigerate 6 hours or overnight.
  8. Add the cream and vanilla into the custard. Fill your ice cream machine according to the manufacturer’s instructions – usually about ⅔ full. Keep remaining custard in the fridge until ready to freeze.
  9. Top with maple syrup for some genuine French toast flavor.

6. Fake Crepes

Don’t you just love those thin slightly chewy golden crepes that you can fill with anything from sweet cream and berries to tomato sauce and a fried egg?

Me too!. Can I make them? So far? No. I just eat tortillas. Which is what we are going to use here.

Use your leftover French toast batter to make a Fake Tortilla Crepe. It’s French-Tex-Mex-American-Tired Mom Fusion if anyone asks. 

Dip flour tortillas in your leftover French toast batter and cook them up on a hot griddle or non-stick pan.

Toast one side for a few seconds until it starts to brown, then flip it over and let the other side brown.

Roll the tortilla crepe up and serve just like French toast with whipped cream and berries.

You could also try it like a sopapilla with cinnamon sugar and honey. Maybe try it like my brother-in-law’s crepes with Nutella.

This is a quick and easy way to use up some leftovers in the cabinet.

7. French Toast Monkey Bread

Monkey bread is made from little balls of dough rolled in cinnamon, sugar, and butter.

You layer the dough in a loaf pan and bake it like a loaf of bread. When it comes out of the oven all bubbly warm, you don’t need to slice it. Just pull off individual bites of bread. 

If you have some leftover french toast batter and a refrigerated can of biscuits, you can make a quick cheater version of Monkey bread. Here are the instructions:

  1. Pre-heat the oven to the temperature on the can of biscuits and coat the loaf pan or small round cake pan with non-cooking spray.
  2. Break the biscuits into bite-sized pieces and dip them into the leftover French batter.
  3. Layer the biscuit bites in the loaf pan.
  4. Melt 2 tablespoons of butter and pour over the monkey bread. 
  5. Until the biscuits are done through 15-20 minutes. (check by inserting a knife into the middle of the loaf)
  6. Serve with syrup or whipped cream.

8. French Toast Casserole

You can use your leftover French toast batter to make a personal size bread pudding or casserole.

Gather up 2-3 thick slices of stale bread, raisins (if you like them), and some brown sugar along with your French toast batter. You will also need a small baking dish like a ramekin. 

Instructions:

  1. Preheat the oven to 425 degrees. Cut the bread into 1-inch cubes.
  2. Layer them in your ramekin or small baking dish and sprinkle in the raisins. 
  3. Pour the French toast batter over the bread and press it gently to ensure that the liquid gets through all the bread. 
  4. Sprinkle a bit of brown sugar on top.
  5. Bake at 425 for 10 minutes then cover with foil and bake for another 10-15 minutes until firm all the way through.

9. Make a Fruity Toasted Sandwich

Maybe you just need a new way to eat your French toast. Try using it for sandwich bread. You will need to make sure that you use thick slices of bread so it doesn’t become too soggy. 

  1. Make the sandwich first, before you dip the bread in the mixture. Spread your toast with Nutella or peanut butter. Or, make a sandwich with whipped cream cheese and sliced strawberries or bananas.
  2. Next, dip the whole sandwich in the french toast batter and cook in a hot skillet or griddle. Try to soak a little less batter than you normally would so the bread crisps up a bit better.

10. Monte Cristo Sandwich

This may be the craziest way to use up leftover sandwich fixin’s in your fridge. It is also the tastiest way to do it.

You can find all kinds of recipes for a Monte Cristo sandwich, but at its essence, this is a grilled or fried ham, turkey, and cheese sandwich with sweetness in the bread and raspberry jam.

Ideally, you build the sandwich, dip it in batter, and deep fry it. However, that can be a challenge at home, so you might try cooking it on a griddle instead.

Ingredients:

  • Leftover French toast batter
  • Sliced bread (white bread, sourdough, King’s Hawaiian)
  • Deli sliced Ham and Turkey
  • Deli sliced cheese (Provolone, Swiss, Cheddar)
  • Dark Mustard (optional)
  • Raspberry Jam
  • Powdered Sugar 

Instructions:

  1. Build your sandwich with ham, turkey cheese, and mustard if you like it. Put a couple of long toothpicks through the sandwich to help it hold together as you move it. 
  2. Dip the sandwich in the leftover French toast batter.
  3. Toast it on a hot griddle until the bread is golden brown and the cheese is melted. Turn the sandwich over once to toast the bread on the other side.
  4. When it is done, cut it into triangles and sprinkle it with powdered sugar. Serve with raspberry jam to dip in. 

11. French Toast Parfait

It has layers! Use your leftovers from breakfast for dinner to make a little parfait for breakfast.

Then stack up some French toast with layers of whipped cream, fruit, fruit-blended yogurt, and even a little granola. Put it all in a mason jar for a portable breakfast.

Final Thoughts

If you don’t get your stale bread to French toast batter ratio correct and end up with extra batter, we have solutions for you.

Use some other kind of bread to make and freeze French toast for a later meal.

Make fake crepes for breakfast tomorrow with the leftover batter. Try out some monkey bread or bread pudding with the remaining batter.

You can even make a fully dipped sandwich like a Monte Cristo or a Nutella and banana sandwich on French toast.

Think out of the box and make an omelet or ice cream! Enjoy some of these tasty options, then go for a walk.
