We all need a solid egg bake in our lives to fall back on, right? ย For me, my go-to lately has been my Crescent Roll Breakfast Casserole that I make over and over again with different veggies and meats each time, but I think that's all about to change with this new guy in town. ย The strata.
The almighty strata takes care of so many problems at the end of a work week/beginning of the weekend. ย For one: that loaf of bread you had every intention of making sandwiches with for lunch throughout the week. ย It's okay, take-out got the best of us, too. ย And second: all of those veggies you meant to eat. ย I'll admit - I'm a veggie lover and don't have a problem using up all the veggies in my fridge, but I have been known to have a carton or two of mushrooms and an unopened bag of spinach left by the end of the week every now and then. ย Sometimes meal plans just get thrown out the window for spur of the moment date nights or lazy frozen pizza nights, and that's ok. ย Strata to the rescue!
Stratas are also great because their heartiness and chunks of bread make them acceptable for breakfast, brunch, lunch, or dinner. ย This one is no exception. ย Do I have you sold on the resourcefulness of stratas yet?! ย They're just the best, I'm telling ya.
This Mushroom, Spinach, and Havarti Strata is one of my new favorites. ย While the ingredients are simple, the flavors work so well together. ย Fresh mushrooms and baby spinach are the star veggies, which are accompanied by chunks of hearty whole grain bread and creamy Havarti cheese. ย While I used Castello Dill Havarti, which was outstanding in this dish, you could use any kind of ย Havarti you like. ย But seriously, try the dill. ย I was skeptical but it works so well in this dish.
Ooooh I just remembered another great thing about stratas! ย They can be made in advance. ย As in, you make it the night before, so when you wake up on Saturday morning you simply pour yourself a cup (or four) of coffee, throw the strata in the oven, and lounge around until breakfast is ready. ย No scrambling to whip up the eggs or fry the bacon, you just let the oven do all of the work in the morning. ย The best.
