This Turkey Strata Breakfast Bake Dish feels like pure comfort in a pan. It is warm, hearty, and just right for a slow morning or a busy holiday brunch. I love how it turns simple leftovers into something that feels special enough for guests, yet easy enough for a regular weekend.
At the heart of this turkey strata are 8 cups day-old sourdough bread, 2 cups leftover cooked turkey, 1 1/2 cups shredded Gruyere or sharp cheddar cheese, 1 cup fresh spinach, 1/2 cup red bell pepper, and 1/4 cup green onion. Then, the custard brings everything together with 8 large eggs, 2 1/2 cups whole milk, 1 tsp Dijon mustard, fine sea salt, black pepper, and a little ground nutmeg. Finally, fresh parsley adds a bright, fresh finish. The flavor is savory, rich, and gently tangy, with a soft, creamy center and a golden top.
The method is simple, too. First, layer the bread, turkey, vegetables, and cheese in a greased 9×13-inch baking dish. After that, whisk the eggs and milk with the seasonings, pour the custard over the top, and let it chill overnight so the bread soaks up every bit. Then, bake until puffed and golden. Because the prep is mostly layering and whisking, this breakfast bake feels easy even when life is busy.
This is a wonderful dish for chilly mornings, holiday breakfasts, and weekend brunches. It also works well for potlucks, since it travels nicely and serves a crowd with very little fuss.

Why You’ll Love This Turkey Strata Breakfast Bake Dish

- It is hearty enough for breakfast, brunch, or even a light dinner.
- The overnight chill saves time in the morning, which is a big help for guests or holidays.

Turkey Tips
For the best turkey strata, use cooked turkey that is moist, not dry. Leftover roast turkey, Thanksgiving turkey, or even store-bought cooked turkey all work well. If the turkey seems a little dry, the custard will help soften it as the dish chills and bakes. Also, shred or dice it into bite-size pieces so it spreads evenly through the layers. That way, every slice of turkey strata gets a good balance of bread, cheese, and turkey.
Options for Substitutions
- Use ciabatta, brioche, or French bread instead of sourdough if that is what you have on hand.
- Swap the turkey for cooked chicken, ham, or even crumbled breakfast sausage.
- Use Swiss, mozzarella, or white cheddar in place of Gruyere or sharp cheddar.
- Replace the spinach with kale, Swiss chard, or cooked broccoli florets.
- Use yellow onion instead of green onion for a deeper, sweeter flavor.
- Try half-and-half or whole milk plus a splash of cream if you want a richer custard.
Watch Out for These Mistakes
One common mistake is using bread that is too fresh. Soft, fresh bread can turn mushy fast, so day-old sourdough works much better. It holds its shape, yet it still soaks up the custard well. If your bread is very fresh, leave the cubes out for a few hours first, or toast them lightly.
Another issue is skipping the overnight chill. This step matters because the bread needs time to absorb the egg mixture fully. If you rush it, the turkey strata can bake unevenly, and you may end up with dry spots in the middle. So, if possible, let it rest for at least 6 hours, and overnight is even better.
Seasoning matters, too. Since bread and eggs are mild, the salt, pepper, Dijon mustard, and nutmeg help build flavor. If you underseason the custard, the finished dish may taste flat. On the other hand, do not add too much salt, especially if your cheese or turkey is already salty.
Also, be careful not to overbake it. The top should be golden and puffed, but the center should not look wet or shaky. Once the knife comes out clean, pull it from the oven and let it rest. That short rest helps the turkey strata set, so each slice comes out neat.

What to Serve With Turkey Strata Breakfast Bake Dish?
This turkey strata breakfast bake pairs nicely with fresh fruit, a simple green salad, or roasted breakfast potatoes. If you want a fuller brunch, add crispy bacon, a bowl of yogurt, or a light fruit salad on the side. For drinks, coffee, tea, or fresh orange juice all fit well. Since the strata is rich and savory, a bright side helps balance the plate.
Storage Instructions
Store: Place leftovers in an airtight container and refrigerate for up to 4 days. Let the dish cool first before storing.
Freeze: For longer storage, wrap individual portions tightly and freeze for up to 2 months. Thaw overnight in the refrigerator for the best texture.
Reheat: For the microwave, warm single portions for 1 to 2 minutes until heated through. For the stovetop, place a portion in a covered skillet over low heat with a tiny splash of water, then warm gently. You can also cover the dish with foil and reheat in a 325°F oven for 15 to 20 minutes.

Ingredients
- 8 cups day-old sourdough bread, cut into 1-inch cubes
- 2 cups leftover cooked turkey, shredded or diced
- 1 1/2 cups shredded Gruyere or sharp cheddar cheese, divided
- 1 cup fresh spinach, roughly chopped
- 1/2 cup red bell pepper, diced
- 1/4 cup green onion, sliced
- 8 large eggs
- 2 1/2 cups whole milk
- 1 tsp Dijon mustard
- 1/2 tsp fine sea salt
- 1/4 tsp freshly ground black pepper
- 1/4 tsp ground nutmeg
- 2 tbsp fresh parsley, chopped

Step-by-Step Instructions
Step 1: Prep the Baking Dish and First Layer
Grease a 9×13-inch baking dish well. Then spread half of the cubed sourdough bread evenly across the bottom. This first layer gives the turkey strata a solid base and helps the custard soak in evenly.
Step 2: Add the Turkey, Vegetables, and Cheese
Scatter half of the shredded turkey over the bread. Next, add 1/2 cup of cheese, then layer on the spinach, red bell pepper, and green onion. Try to spread everything out evenly so each bite has a nice mix of flavors.
Step 3: Build the Second Layer
Top with the remaining bread cubes, followed by the rest of the turkey and another 1/2 cup of cheese. Save the final 1/2 cup of cheese for the top right before baking. This helps the turkey strata bake with a rich, golden crust.
Step 4: Make the Custard
In a large bowl, whisk together the eggs, milk, Dijon mustard, salt, pepper, and nutmeg until smooth. Then pour the mixture evenly over the layered bread. Press down gently with a spatula so the bread starts to soak up the custard.
Step 5: Chill Overnight
Cover the dish tightly and refrigerate overnight, or for at least 6 hours. This resting time is important because it gives the bread time to absorb the liquid fully. As a result, the turkey strata bakes up tender and cohesive instead of dry in the middle.
Step 6: Bake and Finish
The next day, let the dish sit at room temperature for 20 minutes while the oven heats to 350°F. Remove the cover, sprinkle the remaining cheese over the top, and bake uncovered for 45 to 50 minutes. When it is deeply golden and the center is set, let it rest for 10 minutes. Finally, garnish with parsley and serve warm.

This Turkey Strata Breakfast Bake Dish is a cozy, dependable recipe that turns leftover turkey into a satisfying meal. With sourdough bread, cheese, vegetables, and a rich egg custard, it delivers comfort in every bite. Plus, the make-ahead step makes mornings much easier.
