Keto Overnight French Toast  Casserole

I really love this simple low carb brunch casserole because everything can be done the day before. In the morning you can just pop it in the oven for 30 minutes or so and enjoy it with sausage and/or bacon.

And it’s so much easier than making individual French Toasts!

Special bonus: I discovered that cold leftovers taste like Pecan Pie!

Things You Will Need to Make This Low Carb French Toast Casserole

  • 4-5 Chaffles or slices of Low Carb Bread (I made it with Chaffles)
  • Eggs
  • Heavy Cream
  • Cinnamon
  • Pecans
  • Sweetener. For the casserole base you will want an erythritol blend like this So Nourished sweetener. For the candied pecan topping I recommend a brown sugar replacement like Sukrin Gold.

You will also need these tools:

  • Glass pie plate or casserole dish (9 in plate or 9×13 pan)
  • Mixing bowl
  • Waffle Iron (if you are using chaffles instead of bread)

Overnight French Toast Casserole Tips and Tricks

  • Assemble your casserole the night before to let the chaffles or bread soak up the liquid.
  • Check out the graphic below to visually see how to make chaffles. (or you can use low carb bread! but the chaffles are excellent!)
  • You can also get more details here about how to make a basic chaffle.
  • Remember you will need 4 chaffles so double the amounts in the graphic below since it shows instructions for making 2 Chaffles!

  1. Just found….more….it is after 3 p.m.
    I have been searching since I ended my last letter to you!🇨🇦 Am not sure yet…. But I believe this site sells VAPE smoking supplies…. And flavourings are part of it. Who cares what their business is…. Sell me the flavourings I seek!

    The Lorann flavours on this site seem to be half the price when compared to the Gourmet Warehouse!

    They do have a Lorann Buttery Sweet Dough flavour. Four ounces $8.99
    I don’t know… what kind of dough might that be? Like a Challah egg bread?
    Certainly worth the $8.99‼️‼️‼️Sounds delicious to me!

    They also sell a Corn Bread Flavouring for $2.99‼️‼️‼️

    So, then I searched a sweeping broad request of…. FRUIT FLAVOURINGS….
    two very interesting things came up amongst all the abundance of fruit.
    One) sweet cookie flavour AND Two) Pie crust flavour
    If these flavours are added to the PSMF recipe used as a pie crust… that, “right now tastes essentially like nothing” Janet, Greta ……. Then we could really bake a spectacular PSMF pie, that tastes more “pie-like!”

    And they sell a couple of brands of Black Currant! Yeah!
    And several varieties of apple flavour plus apple pie!

    And they have free shipping over $99! They are Canadian.
    Any thoughts?
    As aforementioned…. This is where to shop.

    Perhaps down the road….the only US flavour I would want is the FRESH BAKED BREAD flavour, if I am not so pleased with this Sweet Bread Dough. That would save a lot of money!

    Have I overwhelmed you?
    Hope not!

    1. Sorry, I am very behind in everything! Thanks for all the detailed info! I have not been happy with the drops I have been trying lately, seems no matter how many I add, just not getting the flavor I want. I am sticking to seasonings instead. Let me know if you have better luck with yours and how much you are adding to get some flavor!

  2. Good morning,
    Oh, the idea of this sounds simply delicious.
    Yeah, me, who finally purchased a stand mixer and the ingredients to bake a PSMF loaf of bread. I will bake a loaf today. Just received my 1 kg of cream of Tartar from Everyone seems to run out of Cream of Tartar and here the 2 ounce bottle is $8.99🇨🇦💵 so, the 1 kg box looked reasonable at $42.00.

    Am I reading this correctly? This makes 12 servings, which is 1/3 egg per person?
    How small is a serving? One bite?

    Also, may I ask what size of baking dish did you use? 6×4 perhaps?
    I am amazed that so many women post recipes and never include pan sizes.
    Nor do they include cup volumes that are a serving size for soup. Sigh. It makes everything so hard. Anyway. This is something I will try as soon as I bake bread!

    There is so little info about PSMF on line. I wish there was more!
    Thanks for all your hard work.

    Toronto, Canada🇨🇦

    1. It’s a casserole pan so 9×13 pan would be about right. This recipe is quite rich and would probably be eaten along side other brunch items. Feel free to have more than 1/12th of the pan though!
      Also since it sounds like you are doing PSMF, you might want to check out the one I did on yourtube, you can actually see how I did it and I used PSMF bread instead of chaffles!

      1. Thank you, I will. It sounds like your casserole’s ingredients are very shallow.

        I am still trying to figure out the protocols of this diet! Maria Emmerich’s PSMF book does not come out until late December.

        I have found a flavouring / extract called “fresh baked bread flavoring”🍞 from in California, 🇺🇸and I have been wondering if it would improve the taste of the PSMF bread. I was on a journey seeking “sweet corn flavouring,” too.🌽 And they offer that, too….. Wendy, from Loving it on keto, makes cornbread from leftover yolks. Right now, for the first time, I am using carton egg whites, but they are as expensive as real eggs.
        So, I will stick to fresh eggs and benefit from the yolks too.

        Plus, a dear childhood memory for me is Black Currant jam. My grand mother had several bushes in her yard, and every year would make Black Currant jam. I was the only grand child she ever shared her jam with. So, I am thinking of making my own jelly. Keto of course. This company sells Black Currant Oil.
        This company does indeed want all my money, to be sure.

        It also offers specially formulated ice cream flavourings so that the flavours do not lessen during freezing and over time.

        I will go big on my order. To offset shipping, taxes, duty, and the collection of these by the shipping company. I will save up. But, that bread flavouring has me dreaming! I bet it would work when baking a regular keto bread recipe using almond flour that requires a flavour boost. Those loaves are bland.

        Thanks for reading,
        Time for my morning coffee,☕️
        Stay safe😷

        1. ok, just want you to know that these French Toast casseroles are not PSMF friendly because PSMF is low carb but also low fat! Have you read my article about PSMF? That would be a great place for you to start and it will point you to Maria’s calculator to figure out your PSMF macros.
          The flavorings sound great and of course you are always free to flavor up any recipes as much as you want! I wish there was a place here in Canada to get these things!

          1. Thank you for the referral to your PSMF info.
            Here is info for you…

            I am searching the world for flavours. Here is what I found in Canada!🇨🇦

            One good source in Canada is 🇨🇦Michaels, you know the hobby shop. They sell a small unique selection of Lorann flavourings.

            Next, there is 🇨🇦…. They sell very concentrated flavours at very reasonable prices. The bottles read…. “One ounce flavours one gallon!” But the staff told me that many bakers experiment by using a few drops. From this supplier I bought the following flavours, grapefruit, blood orange, peanut butter, apricot, watermelon, mango, chocolate, toasted marshmallow. These flavours are not run of the mill. I have not used any yet. I will soon.

            And, on the west coast, there is… the gourmet warehouse🇨🇦 that fill in other flavours. Quite frankly, I would rather shop Canadian too.

            But those Sweet corn and Fresh baked bread flavours from 🇺🇸
   are simply calling me! And look at their bottle sizes, and prices. Imagine transforming the PSMF basic bread to a bread that tastes yeasty and buttery!?!? Yum? It will revolutionize this way of eating,

            I first baked the original 2013 Wonder bread recipe. It turned out too dry. It had the consistency of styrofoam and tasted like it, too. I never baked it again. But intrepid YouTube bakers, just like you, have improved it immensely along the way. I just thought I could add to the flavour!

            I have created a delicious bread maker keto bread recipe 2 gr carbs a slice. But I will leave it for occasional eating. Only 1.25 cups of almond flour and 2 eggs, too. Great texture, especially the next day!

            But now, I am falling in love with PSMF bread. I just want to truly enjoy eating it every day in every way.
            Here is another question for you, please.
            I also bake a Keto Black Russian Pumpernickel Bread, inspired by my late friend Maya, who was Russian, and passed from Leukaemia.
            It uses instant coffee, cocoa powder and caraway seeds to create that distinctive flavour and aroma. I am wondering if I can turn the egg white bread into Pumpernickel? Any thoughts? You are the expert!

            Any way, thanks for the encouragement on flavouring the PSMF bread. I know at some point, I will bite the bullet and buy that 🇺🇸flavouring. Look up the Fresh baked bread flavour… and how the prices jump per size of bottle. Wish I was living close to you…. We could share!

            And I have just purchased 1kg Cream of Tartar from Amazon Canada…$42.00. It never goes bad as long as the container is well closed! Better than $8.99 for 2 ounces at my local discount grocer!

            Wonderful speaking with you!
            Support is so very welcomed,
            Gladys 🇨🇦
