what is a strata?
A strata is simply a casserole made predominantly out of eggs and bread, where you can add any veggies, meats, nuts, fruit or other goodies inside. It’s easy to pull off (with whatever you have on hand), and it’s also an inexpensive meal you can enjoy any time of day.
What do i need to make this Vegetarian Apple Caramelized Onion Gluten Free Strata
The best part of making this vegetarian strata is that there really are no rules. For this cold weather, I like the comfort food combination of apples, caramelized onions and chevre, but you can totally throw in whatever you want. Here’s my current love list:
- Baby kale
- Dijon mustard
- Gluten free sourdough bread
- Gruyere cheese
Again, if you don’t have or don’t like some of these ingredients, don’t worry about them! Swap in whatever you have on hand.
how do i make an egg breakfast casserole entertaining worthy
It’s all in the details. I start by caramelizing the onion, then adding in the garlic, sage, and rosemary. Then I wilt down the kale and a pinch each of salt, pepper and nutmeg. In another bowl, mix together the eggs, milk, mustard, apple, some gruyere cheese and a pinch each of salt and pepper.
I arrange my diced bread into a casserole dish and top it off with the egg mixture before I finish with the remaining gruyere and chevre.
Now, I 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!
Finally, an hour before guests arrive, I preheat my oven and bake it off until golden brown.
can i make this strata casserole not gluten free?
The only ingredient with gluten in this vegetarian strata is the bread, so if you don’t have any gluten free guests you’re entertaining, then definitely use regular sourdough bread. I also really do love the flavour of sourdough but if you have another tasty bread at your house, go with that.
tips for perfecting this Vegetarian Apple Caramelized Onion Gluten Free Strata
I’ve made a lot of stratas 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.
can i add other ingredients to this gluten free strata?
Totally! You can addd whatever veggies or cheese you want, and if you don’t want it to be vegetarian, you can also add in some breakfast sausage, bacon or leftover chicken.
could this baked egg casserole be made ahead of time for entertaining?
I recommend prepping it the day before and then baking it off an hour before guests arrive. However, you can bake it the day before or at home and then transport it to another hosts’ home. Just reheat it at 250 F for 20 minutes until warm.
