1 ½ lb breakfast sausage, casings removed Spicy Italian or smoked turkey work well as alternatives.

4 cups fresh spinach, roughly chopped If using frozen, thaw and squeeze out excess water.

1 ½ cups shredded sharp cheddar Gruyère or mozzarella can replace for different melt.

6 large eggs Room‑temperature eggs blend more smoothly.

1 ½ cups whole milk Half‑and‑half or oat milk can be used for richer custard.

¼ cup heavy cream Adds silkiness; optional for lower‑fat version.

1 tsp kosher salt Adjust if sausage is already seasoned.

½ tsp freshly ground black pepper Adds subtle heat; optional.

Instructions

Prepare the Base

Preheat oven to 350°F (175°C). Grease a 9‑x‑13‑inch baking dish. Spread the cubed sourdough evenly across the bottom, creating a uniform layer that will soak up the custard.

Pro Tip: If you like extra crunch, toast the bread cubes lightly before layering.

Cook Sausage & Spinach

In a large skillet over medium heat, crumble the sausage and cook until browned, about 6‑8 minutes. Add the spinach, stirring until wilted, then season with salt and pepper. Transfer the mixture over the bread cubes.

Pro Tip: Drain excess fat before adding spinach to avoid soggy layers.

Add Cheese

Sprinkle the shredded cheddar evenly over the sausage‑spinach layer. The cheese will melt into a golden crust and add a rich, savory depth to every bite.

Whisk Custard

In a bowl, whisk together eggs, milk, cream, salt, and pepper until fully combined. Pour the custard evenly over the assembled layers, allowing it to seep into the bread for a moist interior.

Bake to Perfection

Cover the dish with foil and bake for 25 minutes. Remove foil and continue baking 15‑20 minutes, or until the top is golden and a knife inserted in the center comes out clean. Let rest 10 minutes before slicing.

Expert Tips

Tip #1: Use Day‑Old Bread

Stale sourdough absorbs the custard without turning mushy, giving the strata a light, airy texture.

Tip #2: Cool the Custard

A few minutes of chilling prevents the custard from cooking too quickly when it hits the hot pan.

Tip #3: Add a Crunch Topping

Mix breadcrumbs with a drizzle of melted butter and a pinch of paprika; sprinkle before the final bake.

Tip #4: Serve Warm

The strata holds its shape best when sliced within an hour of baking; reheat gently if needed.
