When we host Shabbat dinner, we always have leftover challah. Since I don’t like sweets in the morning, I created this everything bagel savory challah strata with lox for Shabbat mornings instead. Besides being able to assemble this the night before, the best thing about this recipe is that you can customize it to any amount of challah you have left! —Kristin Eriko Posner
challah, cut into 1" cubes (don't pack measuring cups, just loosely fill them)
eggs (about 8 eggs)
shredded mozzarella cheese, handful reserved for later
lox, cut into roughly 1" squares, be sure to separate the pieces so they're not all stuck together from chopping
thinly sliced green onions
chopped dill, handful reserved for later
grated parmesan cheese
everything bagel mix
In This Recipe
For the pickled red onion: Thinly slice 1/4 of a red onion. Place it in a bowl with 1/2 teaspoon salt, 1 tablespoon of honey and 1/2 cup vinegar (white wine, rice and apple cider all work- anything light in color). Let it pickle while you prepare the rest of the strata.
Butter the baking dish and set the oven to 350°.
Fill the baking dish with the cubed challah.
Place milk and eggs in a large mixing bowl and whisk until well incorporated.
Add mozzarella cheese, reserving a handful for later.
Add lox, green onions, and chopped dill, reserving a handful for later. Sprinkle in salt and pepper. Stir again.
Pour this mixture evenly over the cubed challah. You may need to push the challah down into the liquid to make sure most of the pieces are soaked through. Fluff it back up so the top layer looks nice and there are no holes where the challah was pushed down.
Cover the strata in foil and bake for 20 minutes.
Remove the foil and sprinkle the strata with remaining mozzarella, grated parmesan cheese, and everything bagel mix. Bake for another 20 minutes. Check on it often to make sure the cheese isn’t burning (it should be golden brown). To test for doneness, remove the pan from the oven and give it a shake- if it doesn’t jiggle, it’s done.
Sprinkle with remaining dill and pickled red onions. Let it rest for five minutes and serve while warm.
You can prepare everything up until step 8 the night before. Simply remove it from the fridge 30 minutes before baking.
