Come closer. This isn’t your run-of-the-mill French toast casserole. This one’s got a little twist, zucchini bread. And not just any zucchini bread, but keto zucchini bread, all tucked into a warm, soft, slightly crispy-on-top French toast bake that doesn’t mess with your carbs. This is the kind of thing you prep the night before and look forward to waking up for. The kind of thing that makes sticking to a low carb breakfast feel less like a chore and more like something you’re glad you started doing.

You know those moments when you want something sweet for breakfast, but you’re trying to stay on track? This right here hits that balance. Soft, lightly sweet bread soaked in creamy eggs, spiced just enough, baked golden. And yeah, it’s low carb. No weird textures. No “okay but it tastes keto” disappointment.

Let’s get right into the kitchen. I’ll walk you through it like you’re right here beside me. We’re not rushing this. We’re making it count.

What We’re Making

We’re starting with a loaf of keto zucchini bread. It’s spiced like a hug, think cinnamon, a little nutmeg, a touch of vanilla. From there, we’ll turn that bread into a French toast casserole. This bakes up like bread pudding meets French toast, soft inside, golden on top. You can do it as an overnight bake or make it fresh in the morning. Either way, you’re winning.

What You Need For Keto Zucchini Bread French Toast Casserole

For the Zucchini Bread:

• 1 cup almond flour

• 1/4 cup coconut flour

• 1 tsp baking powder

• 1/2 tsp baking soda

• 1 tsp cinnamon

• Pinch of nutmeg

• 1/4 tsp salt

• 3 large eggs

• 1/4 cup melted butter or coconut oil

• 1/3 cup granulated erythritol (like Swerve or Monkfruit)

• 1 tsp vanilla extract

• 1 cup grated zucchini (squeeze out extra moisture)

For the French Toast Casserole:

• 6 slices of the zucchini bread (thick-cut is best)

• 3 large eggs

• 1/2 cup heavy cream

• 1/4 cup unsweetened almond milk

• 1 tsp vanilla extract

• 1 tsp cinnamon

• 1 tbsp granulated erythritol

• Butter for greasing the dish

Let’s Bake That Bread

You can’t rush a good base. And our base? That’s the zucchini bread. You could use any keto bread, sure, but using one that already has flavor baked into it makes all the difference. You want your French toast to taste like something, not just egg-soaked fluff.

• Preheat your oven to 350°F (175°C).

• Grease a small loaf pan (8×4 works great) and line it with parchment paper.

• Mix all the dry ingredients in one bowl.

• In another, whisk your eggs, butter, vanilla, and sweetener. Stir in the grated zucchini.

• Combine wet and dry, don’t overmix. Spoon it into your pan.

• Bake for 45-50 minutes or until a toothpick comes out clean.

• Let it cool completely before slicing. You can make this the day before.

Turning That Bread into French Toast Casserole

Here’s where the magic happens. Think of this as the keto stuffed french toast version you didn’t know you needed. You could even sneak in some cream cheese between layers if you’re feeling fancy.

If You’re Making It Fresh:

• Cut 6 thick slices of your cooled zucchini bread.

• In a bowl, whisk eggs, heavy cream, almond milk, vanilla, cinnamon, and sweetener.

• Lightly grease a small baking dish (an 8×8 is perfect).

• Lay your bread slices in the dish. You can cube them or lay them flat. Pour the egg mix all over.

• Let it soak for 10-15 minutes, pressing the bread down a bit to soak it up.

• Bake at 350°F for 30-35 minutes until golden on top and set in the middle.

For an Overnight Version:

1. Follow the same steps, but cover and chill overnight.

2. In the morning, let it sit at room temp for 20 minutes while the oven heats up, then bake.

This version makes mornings easier. Like, actually easy. You wake up, turn on the oven, sip your coffee, and boom—low carb breakfast bread recipes just made your morning.

Keto Toppings That Taste Good

Skip the syrup aisle. You’ve got better options.

• A dusting of powdered erythritol

• A spoonful of whipped cream

• Fresh berries (if you’re keeping net carbs in check)

• Chopped pecans or walnuts for crunch

• A dollop of keto cream cheese frosting (yes, really)

Why This Works When You’re Losing Weight

Because it’s satisfying. You’re not just chewing through another bland keto bread french toast. You’re eating something with body, warmth, flavor—and it keeps you full. That’s what makes it easier to stick with eating low carb without falling into old habits.

It checks the boxes:

• No added sugar

• Grain-free

• Feels like dessert, works for breakfast

It’s not just breakfast low carb style. It’s a breakfast that feels like a treat without messing with your day.

Want More Ideas?

You can flip this into different low carb dessert tricks too. You’ve already made the base. Now imagine mini versions of this as keto french toast muffins, same idea, just baked in muffin tins. They’re great for portion control and freezing.

Or turn this into stuffed French toast. Cut that zucchini bread, spread a bit of sweetened cream cheese inside, sandwich it, soak it, bake it. Boom—keto stuffed french toast without the fuss.
