3/4 cup swiss or gruyere cheese grated and divided
2tbsp chevre
Instructions
Lightly grease a 9x13 inch casserole or gratin dish.
Add the oil to a large nonstick skillet over medium high heat, and add in the onions and cook on a medium low heat until golden brown, about 30 minutes. Then stir in the garlic, sage, and rosemary. Cook until fragrant. Add in the kale and a pinch each of salt, pepper and nutmeg.
In another bowl, mix together the eggs, milk, mustard, apple, 1/4 cup of gruyere cheese and a pinch each of salt and pepper. Add in kale and onion mixture and combine.
Arrange the Promise gluten free sourdough bread into a casserole dish, and top with the milk and egg mixture. Finish with the remaining gruyere and chevre. Cover and refrigerate for 1 hour or up to overnight.
Preheat oven to 350 F.
Bake uncovered for 45-50 min or until golden brown.
Notes
I've made a lot of egg strata's in my day, and here's what I've learned.
Use day old bread if you can! It will soak up the egg better and not get soggy
Put the cheese into the casserole and on top!
Let the strata rest for 5-10 minutes before you cut and serve it.
I also like to cover and refrigerate for 1 hour or up to overnight. This is why this dish is sooooo amazing for entertaining - because all of the work can happen the day before! An hour before guests arrive, I preheat my oven and bake it off until golden brown and voila! Done.While we love to use gruyere in this recipe for its super melty consistency and nutty flavour, some vegetarians may wish to avoid this option as gruyere has rennet which technically makes it non-vegetarian. Swiss cheese, on the other hand, is a great fully vegetarian friendly option and is just as delicious!
