  1. i lived in london for 4 years – and the rain and fog are not as bad as people claim them to be. i actually loved it there – and i am proud to say i didn’t own an umbrella for the vast majority of my sojourn over there 😉

  2. Shanna, you know my love of London! The fist day I moved there, it seemed as though I was in a monsoon! However, soon after, most of the rainy days that followed were very light and manageable, but I did enjoy staying indoors and cooking up tasty meals. To be honest, I think the rain this weekend was worse! So thank you for giving me a new recipe to try! I’m sure there will be tons of snowy days in a few months – and I’ll be constantly checking your blog for updates!

  3. Thanks for the comments, guys! Since you’ve both lived there, you know it better than I would–Amy, SO impressed you didn’t own an umbrella.

    Carrie, I’m loving your blog, too! 🙂

    • I made this dish for our church group and it was a big hit! Thank you for this delicious recipe, I will definitely be making it again!

  4. That rain last weekend was pretty crazy, but I love the excuse to cuddle up on the couch and stay inside. We had a friend in town, though, so it was bad timing to be so wet! I think I like it better when it’s cold and snowy… although the cold and snow here lasts longer than I like. I don’t know what climate would actually keep me happy 😉

    This egg bake sounds tasty. I need to do brunch with friends soon… it would be so fun! I hope your internet is fixed by now!

  5. I am so with you about loving staying home on the couch. There’s nothing cozier than a rainy day at home! As far as snow–is it just me, or were the last two winters unending? I haven’t quite recovered from all our snowstorms last year (or the driving in them). Thankfully we’ve still got fall to enjoy. 🙂

    • Absolutely! Refrigerating overnight allows the egg mixture to soak into the bread. Most strata-type recipes like this one recommend refrigerating for anywhere from 1 to 24 hours before baking, but you could put the casserole in the oven right away if you wish to. We recommend a minimum of 30 minutes. Note that the texture of the finished product may be slightly different and you may need to reduce the baking time slightly since the ingredients and dish may not be as cold when you place them in the oven.

      • Allison, you stated “Refrigerating overnight allows the egg mixture to soak into the bread”, but bread is not listed in your ingredients or instructions. Please clarify – how much bread? What kind of bread? Whole slices or cut up? Thank you!

        • I’m so sorry for the confusion, Janie – I was thinking of this recipe. You are correct that there is no bread in this overnight egg bake, and soaking overnight is not actually required. Some versions of a recipe like this one also include about 1/2 cup of flour mixed in, which can benefit from a little soaking. But in this case, the “overnight” is more of a suggestion, for make-ahead convenience. It isn’t required.

          Reply
    • Sorry Kira- I was thinking of a different recipe, as noted below. Soaking overnight is not required to make this, though it can be prepped in advance.

  6. Thank you very much for this excellent dish! I made it with thick cut bacon which I had baked. I’ve made several overnight egg casseroles but the flavors & texture of this is the best! My husband & father in law agreed!! I will make it for a brunch gathering.
