caramelized onion and spinach breakfast strata

we’re all about the breakfast bakes right now apparently. mostly because i’ve been looking for more recipes that i can bake up at the beginning of the week and we can heat it up for multiple days. breakfast is one of the hardest meals for me, and it makes things so much easier when you have two toddlers to cook for in the morning, especially since ryan just left on a month long training. #militarylife. i love this caramelized onion and spinach strata because it’s easily customizable, you can add whatever you have on hand… next time ryan suggested i add potatoes and i’m definitely going to try that. eggs have so much nutrition, and it’s a fun way to get veggies in at the morning meal, as well as helping me use up yesterdays stale sourdough, which i always feel like gets wasted. homemade bread goes stale so fast because there are no preservatives, and casseroles are an amazing way to use that up. you can use whatever bread you have laying around! i find a crusty leftover loaf of bread works really well with this recipe though, because it stands up to the egg mixture and retains some chewiness rather than becoming all soggy in the casserole. hope you enjoy this yummy strata as much as we did! 🙂

ingredients

9 large eggs
1 1/2 cups milk
1/4-1/2 cup heavy cream
1 yellow onion, thinly sliced
1-2 cloves of garlic, minced
2 cups fresh baby spinach, chopped or just ripped into pieces
half a loaf of crusty bread, cut into 1 inch cubes (about 2-2 1/2 cups)
1 cup shredded cheese of choice
1/2 teaspoon salt
freshly ground black pepper to taste (about 1/2 teaspoon, but adjust based on your preferences)
1/2 teaspoon smoked paprika
1 tablespoon butter
1 tablespoon olive oil
cooking spray or extra butter to coat baking dish

instructions

preheat your oven to 350 degrees. slice the onion thinly, add the butter and olive oil to a non-stick skillet over medium-low heat. sauté the onions until they start to caramelize and brown, about 7-10 minutes. add the minced garlic and cook for one more minute, then take off the heat to cool slightly. honestly, you could caramelize these fully and it would add a more complex flavor, but i was being lazy and just got a little dark brown color on them knowing they would cook all the way through in the oven. while the onions are cooling, slice up your bread into 1 inch cubes, and set aside. whisk together the eggs, milk, heavy cream, shredded cheese, salt, pepper, smoked paprika and cheese. fold in the spinach and onion/garlic mixture and the bread cubes. spread evenly into a 9×13 baking dish that’s been sprayed with cooking spray or lined with butter. bake for 45-50 minutes, or until the bread is a golden brown, and it’s completely set in the middle. then enjoy for breakfast, brunch, lunch, or dinner!
