Step 1

Preheat the oven to 400 degrees F.

Step 2

Toss the bread cubes with 1 tablespoon oil and spread evenly in a single layer on a rimmed baking sheet. Bake until the cubes begin to turn light golden around the edges, 10 to 12 minutes (do not over-brown as the bread cubes will continue to brown when baked atop the sausage in the dish). Remove from the oven and set aside.

Step 3

Heat the remaining oil in a large nonstick skillet over medium-high heat. Add the onion and sausage. Break up the sausage with a wooden spoon and cook until the sausage has cooked through and the onion is soft, 8 to 10 minutes. Add the spinach and cook, stirring frequently, until wilted, about 2 minutes. Add the sun-dried tomatoes and basil.

Step 4

Season with 1/2 teaspoon salt and 1/4 teaspoon pepper. Spread the mixture evenly into a 13-by-9-by-2-inch glass baking dish or ceramic baking dish. Sprinkle the goat cheese on the mixture and arrange the bread cubes on top. Make 6 slight indentations in the mixture, spacing apart. Cover and chill. This can be prepared 2 hours ahead.

Step 5

Crack 1 egg into each indentation, making sure to keep the yolks intact. Sprinkle the eggs lightly with salt and freshly ground black pepper.

Step 6

Bake until the egg whites are set but yolks are still runny, about 15 minutes (or 18 minutes for a fully cooked yolk).
