Tips, Tricks & FAQs
Heck no! I soaked this vegetarian strata recipe for less than five minutes – and those buttery croissants soaked up all the moisture!
I would say the most would be overnight – otherwise the bread will get too sogged and have no texture. I would not bake it until you’re serving – the eggs can get rubbery on a reheat. It’s much better fresh!
Meh – I wouldn’t probably. I’ve never been one to like cold eggs.
Your best bet is to stick the center with a knife (gently) and see if there’s any liquid in the center. If there’s still liquid, bake 5 min longer.
Yes – I would bake at 350 for 35-40 minutes. Checking to be sure the top doesn’t get too brown.
Store any leftovers in airtight containers and reheat in the microwave. The steam will help rejuvenate those eggs.

Variations for Vegetable Strata
- Alt Bread – No croissants? Just use any thick sliced hearty bread or even biscuits.
- Veggies – You can pop any veggies in this strata – just be sure they’re lightly sauteed. Mushrooms, bell peppers, onions, asparagus and broccoli would all be delicious.
- Cheeses – Because I was going for caprese – I used tomato/basil/mozz – but you could easily swap with sharp cheddar cheese, Swiss, colby jack, feta, goat or gruyere cheese. Thinking about Parmesan cheese? I would just sprinkle some on top! You want a melty cheese in the strata.
- Herbs – I used fresh basil – but you could also add garlic or fresh thyme for more herbaceous flavor!
- Meat – Yes – this is a vegetarian strata – but maybe you have some meat eaters – you could add bacon, ham or sausage to half of the strata and just mark it off with an asparagus
