Ingredients
Strata Base
Egg Custard
Assembly
Instructions
Prepare Ingredients
- In a fine-mesh sieve, push out as much water as possible from the thawed spinach. Set aside.
- In a large skillet, melt the butter over medium heat and cook onion until it softens, about 4-5 minutes, stirring occasionally.
- Add the garlic and cook for 30 seconds. Stir in the drained spinach and crumbled bacon and set aside.
Make Custard
- Whisk the eggs until well combined in a large bowl.
- Add milk, heavy cream, Dijon mustard, salt, pepper, and nutmeg. Whisk until fully combined.
Assemble and Chill
- Spray a 9-by-13-inch baking dish with cooking spray.
- Layer a third of the bread cubes on the bottom of the pan and top with a third of the spinach mixture.
- Finish the layer with a third of the cheeses (Gruyere and Parmesan combined).
- Repeat the layers two more times in the same order.
- Pour the egg mixture all over the strata, distributing evenly.
- Cover with plastic wrap and refrigerate for at least 1 hour, preferably 8 hours or overnight.
Bake and Serve
- Remove the strata from the refrigerator 30 minutes to 1 hour before baking to promote even cooking.
- Heat the oven to 325 degrees.
- Bake the strata uncovered for 1 hour and 10 minutes.
- Allow the strata to stand 10-15 minutes before serving to set the custard.
Notes
- This strata can be assembled the night before, making it perfect for hosting brunch.
- Make sure to squeeze out as much water as possible from the thawed spinach to prevent a soggy strata.
- The strata can be baked immediately after assembly if you're short on time, though chilling overnight yields the best texture and flavor absorption.
