ingredients needed to make French toast including challah bread, eggs, spices, maple syrup, butternut squash


You’ll need a few ingredients to make this baked challah French toast:

Challah bread: This is the main ingredient of this baked French toast. Challah is an egg bread and is absolutely delicious.

If you’ve never tried challah bread, it’s one of the tastiest breads out there. I grew up eating it during the Jewish holidays with my family. It’s not exactly like French bread or brioche. Because it has a base of egg, I think it’s even tastier!

If you follow a gluten-free diet, you can substitute in gluten-free challah.

Eggs and egg whites: These help bind all the ingredients together and add protein to the breakfast.

Pureed butternut squash: I love baking with butternut squash, as it adds so many vitamins and minerals––as well as fiber.

The butternut squash puree adds so many vitamins and minerals to the dish––as well as filling fiber. I like to use a canned butternut squash to make the recipe even easier to whip together.

Milk: When you let the French toast sit overnight, the challah will sop up the milk. If you follow a dairy-free diet, you can sub the milk for unsweetened almond milk.

he egg-milk mixture is a must for getting creaminess in the French toast.

Vanilla extract, pumpkin pie spice, cinnamon, and nutmeg: What would a baked challah French toast be without lots of warming spices?

You’ll find that the brown-sugar-cinnamon mixture adds a delicious sweetness to the overnight French toast.

Pecans: These add crunch, as well as healthy fats, protein, and fiber.

Raisins: These add additional sweetness and cut down the use of sugar in the recipe. I love cooking with raisins because they add sop up the moisture of the liquid and they’re wonderfully chewy!

This recipe is on the healthier side of things because it contains less sugar and saturated fat than many French toast recipes out there.

Then, when you’re ready to bake your French toast, simply top it with more pecans, preheat the oven to 350° Fahrenheit, and bake for about 30 minutes!

To me, the overnight French toast is plenty sweet on its own. But if you’d like, you can drizzle it with pure maple syrup.

Recipe FAQ

Why is my French toast casserole soggy?

French toast casserole gets soggy when it has too much liquid or when it sits for too long––or both. To prevent it from getting soggy, do not use any milk or other liquid beyond what the recipe calls for and let it sit for no more than one night before baking.

Additionally, the right type of bread is key––it should be sturdy and spongy, so that the liquid can be better absorbed. Challah, brioche, and croissants are perfect for this.

It is also a good idea to use bread that is a little stale and cut into 1-inch cubes, which can help the French toast mixture absorb without the sogginess.

Is brioche or challah better for French toast?

This is a personal decision. Both taste amazing in French toast, and both are eggy yeast breads. However, bricohe has a richer taste.

Both types of bread are full of flavor and have a sturdiness to them that absorbs French toast mix well.

Challah does not contain any dairy. On the other hand, brioche is made with butter and tends to have a richer flavor. It is really up to you as far as what type of bread you use to make French toast!

What can I do with a loaf of challah?

In addition to making this baked challah French toast, you have so many options. You can cube the bread to make homemade croutons, or you can serve it with jam or honey.

What is challah bread good for?

Challah is a yeast bread that is made with eggs and oil instead of butter. It’s great for making sweet recipes and dishes like French toast and bread pudding.

It can also work for making sandwiches and bread-based casseroles (like this baked French toast!). Another option is to make the bread into homemade croutons, or serve the bread with jam or honey. 

How do you reheat French toast casserole?

To reheat French toast casserole, simply place the casserole dish in the oven at 350° Fahrenheit. Leave it in the oven until it’s warmed through, which will take up to 20 minutes.
