Ingredients
1 tbsp. extra-virgin olive oil
12 oz. breakfast sausage, casings removed if necessary
6 tbsp. butter, plus more for baking dish, divided
4 celery stalks
4 medium leeks, finely chopped
1 sweet-tart apple, such as pink lady or granny smith, cored and chopped
kosher salt
Freshly ground black pepper
1/2 c. dry white wine
10 c. torn croissants (about 8 croissants), dried overnight
2 tbsp. freshly chopped sage
2 tbsp. freshly chopped thyme
2 large eggs
3 c. low-sodium chicken or vegetable broth
Preparation
Step 1Preheat oven to 350°. In a large skillet over medium-high heat, heat olive oil. Add sausage and cook, breaking up with a wooden spoon, until browned, 5 minutes. Transfer to a large bowl using a slotted spoon. Add 2 tablespoons butter to skillet along with celery, leeks, and apple. Season with salt and pepper and cook, stirring often, until tender, 6 to 8 minutes. Add wine and cook, stirring, until almost evaporated, 2 minutes. Transfer vegetable mixture to bowl with sausage and add croissant pieces, sage, and thyme and toss to combine.Step 2In a separate medium bowl, whisk together eggs and 2 cups broth. Pour over croissant mixture and toss until evenly moistened, adding more broth ¼ cup at a time until croissant pieces seem hydrated (you might not use it all).Step 3Butter a 3-quart baking dish and add stuffing. Dot with remaining 4 tablespoons butter and cover dish with foil. Bake until a knife inserted in the center of the stuffing comes out warm, 30 to 35 minutes. Increase heat to 425° and continue to bake until top is deeply golden, 10 to 15 minutes more. Let rest 10 minutes before serving.
