It's easy to make and assemble ahead of time, and it's ready in just over an hour!

Strata is the ultimate savory make-ahead breakfast for slow mornings, simple gatherings, and special occasions. It's a no-fuss dish you can prepare the night before so all you have to do is pop it in the oven while you're making your coffee.

Unlike most strata recipes which tend to be heavy, we've lightened this one up with less bread, lots of veggies, and feta cheese (but we also just really love feta)!

If you have leftover ingredients from an Italian meal, you can make this strata in minutes. Day-old bread, spinach, cheese, and cherry tomatoes are what we use, but the recipe is really versatile. You can sub the cherry tomatoes for red peppers, thinly sliced zucchini, olives, or sun-dried tomatoes, and pretty much any cheese and bread will work.

Most people serve strata for breakfast or brunch, but just like quiche, this cheesy vegetarian casserole tastes great for dinner, too. Leftovers can be easily warmed up for an easy (and enviable) office lunch the next day!

What to serve with spinach strata

This tomato spinach strata is hearting and filling and can be served on its own or alongside other breakfast foods like fresh fruit, roast potatoes, sweet or savory pastries, or salad.

Strata doesn't need to be reserved for breakfast and brunch, though. Serve it with a salad and some grilled sausage (or veggie sausage) and you've got yourself an easy and delicious dinner.

Spinach tomato strata ingredients

You don't need many ingredients to make this Mediterranean spinach strata, and you can definitely switch up the ingredients to use what you have in your fridge. Here's everything you need to make this it:

  • Olive oil – for sautéing.
  • Onion + garlic – these aromatics give this strata a delicious base of flavor.
  • Spinach – we use a generous amount of spinach because we like our greens! It also always surprises us how much spinach wilts down when it's cooked. You can also use kale, chard, collards, or other greens.
  • Eggs – the eggs mix with the yogurt to make a creamy custard that soaks into the bread and brings this savory breakfast together.
  • Sea salt – for seasoning.
  • Yogurt – yogurt makes this strata taste rich and creamy while keeping it light and healthy.
  • Feta + parmesan – feta is salty and tangy, and parmesan is bold and nutty. They make a great mix!
  • Cubed bread – any kind of crusty bread works, and it's ok if it's a bit stale.
  • Cherry tomatoes – we use cherry tomatoes, but you can use another small tomato variety or just chopped tomatoes.

  • Bake in the preheated oven for 40-45 minutes, or until the eggs have set. Note: there will be some moisture at the edges of the dish. This is because of the tomatoes. Once the strata rests for a few minutes the moisture will disappear. Let the spinach strata rest for 10 minutes before you dig in.
