Instructions
Grease a 9x13 inch baking dish with butter or cooking spray, including the sides and corners. Cut the sourdough bread into 1-inch cubes and spread them in an even layer in the prepared dish.
Heat a large skillet over medium heat, add the Italian sausage (casings removed), and cook for 7–9 minutes, breaking it into crumbles, until browned and cooked through. Transfer to a paper towel-lined plate to drain.
In the same skillet with remaining drippings, sauté the diced red bell pepper over medium heat for 3–4 minutes until just softened. Remove from heat and set aside.
In a large mixing bowl, whisk together the 8 eggs and 2 cups of whole milk until smooth. Add the dried thyme, salt, pepper, and chopped parsley and whisk to combine.
Scatter the cooked sausage and sautéed bell pepper evenly over the bread cubes, then sprinkle 1 cup of the shredded cheddar on top. Slowly pour the egg custard evenly over everything, then gently press the bread down to help it absorb the liquid.
Cover the dish tightly with foil or plastic wrap and refrigerate for at least 8 hours, or overnight. This soaking time is essential for a rich, custardy texture.
Remove the strata from the refrigerator 30 minutes before baking and let it come to room temperature. Preheat the oven to 350°F (175°C) with the rack in the center position.
Place the foil-covered dish in the preheated oven and bake for 35–40 minutes until the custard begins to set and the edges look cooked.
Remove the foil, sprinkle the reserved ½ cup of cheddar cheese evenly over the top, and return to the oven uncovered for 15–20 more minutes until the cheese is golden and a knife inserted in the center comes out clean.
Let the strata rest for 10–15 minutes before cutting to allow the custard to fully set. Slice into portions and serve warm directly from the dish.
Notes
Use day-old or slightly stale sourdough for the best texture — fresh bread can turn mushy after soaking overnight.
The overnight soak is highly recommended. One hour minimum will work in a pinch, but 8 hours gives you the richest, most cohesive result.
Always remove the strata from the fridge 30 minutes before baking so it cooks evenly from edge to center.
Drain the browned sausage on paper towels before adding to the dish — excess grease will make the strata heavy and greasy.
Reserve ½ cup of cheese to add halfway through baking for a beautifully golden, melted topping rather than a fully buried cheese layer.
Let the strata rest at least 10–15 minutes after baking before slicing — cutting too soon will result in loose, runny portions.
Swap Italian sausage for crumbled bacon, diced ham, turkey sausage, or chorizo for a different flavor profile.
Try Gruyere, fontina, or pepper jack in place of cheddar for variety — a blend of two cheeses works especially well.
Leftovers keep refrigerated for up to 4 days. Reheat in a 325°F oven covered with foil for 15–20 minutes, or microwave individual slices on medium power for 1–2 minutes.
To freeze, bake the strata first, cool completely, then wrap individual portions tightly and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
