Step 1

Slice the bread. Use a serrated knife to cut the loaf of bread into 1 1/4-inch-thick slices. Cut each slice into 3/4-inch wide sticks.

Step 2

Heat the oven and coat 2 baking sheets with butter. Arrange 2 racks to divide the oven into thirds and heat to 375°F. Generously coat 2 rimmed baking sheets with 2 tablespoons of butter each.

Step 3

Make the French toast custard. Place the cream, eggs, sugar, cinnamon, and salt in an 8x8-inch baking dish and whisk until completely and thoroughly combined.

Step 4

Coat the bread sticks in the custard. Working with 1 bread stick at a time, dip and roll it in the custard, swipe off the excess custard back into the baking dish with two fingers, then place the coated stick on a prepared baking sheet. Repeat with the remaining bread sticks, leaving about 1/2 inch between each stick.

Step 5

Bake the French toast sticks. Bake the French toast sticks until golden-brown, using tongs to flip them halfway through, about 10 minutes total.

Step 6

Cool the French toast sticks. Immediately transfer them to a cooling rack so they remain crisp. Cool completely before freezing.

Step 7

Freeze the French toast sticks. Transfer the completely cooled French toast sticks to a gallon-sized zip-top bag, seal, and place in the freezer. It isn't important to individually freeze the sticks first, but they must be completely cool before going into the freezer.

Step 8

Reheat the French toast sticks from frozen. Once frozen, the French toast sticks can be reheated directly from the freezer. Arrange in a single layer on a baking sheet and bake in a 350°F oven or toaster oven for 5 minutes, flipping once about halfway through baking. Alternatively, you can microwave the French toast sticks for 2 minutes on high, but they will not be as crisp coming out of the microwave as they would from the oven.
