Ingredients

– 8 large eggs, pasture-raised (bring to room temperature for fluffier texture)
– 1 cup low-fat milk (whole milk adds extra creaminess)
– ½ cup plain Greek yogurt (optional—makes it ultra-moist)
– 6 slices whole-wheat or sourdough bread, cut into 1″ cubes (day-old loaf works best)
– 1 lb lean breakfast sausage, cooked and crumbled (try turkey sausage for lighter twist)
– 1 bell pepper, diced (red for color, green for zing)
– 1 small yellow onion, finely chopped (white onion also works)
– 2 cups shredded cheddar cheese (sharp or mild—your choice)
– ¼ cup fresh parsley, chopped (adds a bright finish)
– ½ tsp garlic powder (or 2 cloves minced garlic)
– ½ tsp smoked paprika (for that cozy aroma)
– Salt and pepper to taste

Tips:
• Use whole-milk Greek yogurt if you want a richer bite.
• Cube the bread on a baking sheet and toast at 300°F for 5 minutes if it’s too soft.
• Choose a quality sausage like Jimmy Dean or Applegate to boost flavor.

Directions

1. Preheat your oven to 350°F and grease a 9×13-inch baking dish with a thin layer of butter or nonstick spray. This ensures easy release later.
2. In a large bowl, whisk together eggs, milk, Greek yogurt, garlic powder, smoked paprika, salt, and pepper until the mixture looks smooth and slightly frothy—this helps the custard set just right.
3. Scatter half of the bread cubes evenly in the prepared dish. Layer on the cooked sausage, diced bell pepper, and onion; sprinkle with half the shredded cheddar.
4. Pour the egg mixture over the layers, pressing gently with a spatula so the bread soaks up the custard. Toss in those air pockets to ensure even cooking.
5. Scatter the remaining bread cubes on top, then sprinkle with the rest of the cheese and chopped parsley—this final layer crisps up beautifully.
6. Cover the dish tightly with foil and refrigerate for at least 4 hours or up to overnight (make-ahead tip!). The longer it chills, the more cohesive the strata.
7. When you’re ready to bake, remove foil and place the dish on a middle rack. Bake for 35–40 minutes, then uncover and bake another 10 minutes until the cheese bubbles and the top turns golden brown.
8. Let the casserole rest for 5 minutes before slicing—this makes clean cuts and keeps juices in check. Serve warm with a dollop of salsa or a side of fruit.

Notes

During recipe testing, I found pressing the bread into the custard mix really makes each bite tender. If your bread is fresh, give it a quick toast so it holds up. For extra golden edges, switch your oven to broil for the last 2 minutes—watch it closely! I also like stirring in a tablespoon of Dijon mustard for a subtle tang, though it’s totally optional.
