Egg & Sausage Casserole

Inspired by a Midwestern Tater Tot dish, this filling breakfast casserole is packed with lean protein and vegetables. If you can’t find sweet potato Tater Tots, then use a large bag of frozen sweet potato or regular hash browns in their place. It’s the perfect dish when you have extra company in town and are looking to feed a big group, while still keeping things light.

Egg & Sausage Casserole

Ingredients

• Cooking spray
• 8 large eggs
• 1 cup (244g) low-fat milk
• 1/2 cup (123g) plain nonfat Greek yogurt
• 1/2 tsp salt
• 1/2 tsp black pepper
• 1 tbsp olive oil
• 2 large garlic cloves, thinly sliced
• 1 pint (500g) cherry tomatoes
• 1 16-oz. (450g) bags frozen kale or spinach, thawed
• 14 oz. (350g) cooked chicken breakfast sausage, chopped
• 1 20-oz. (567g) bag sweet potato Tater Tots
• 1/2 cup (50g) grated gruyere or shredded Parmesan cheese

Directions

Preheat the oven to 400°F (204°C). Arrange the Tater Tots in a single layer on a rimmed baking sheet and bake for 15 minutes, until lightly golden. Remove from the oven and reduce the oven temperature to 350°F (177°C). Grease a 9-by-13-inch baking dish.

While the Tater Tots bake, whisk together the eggs, milk, yogurt, salt, and black pepper in a large bowl until smooth.

Heat the olive oil in a large nonstick skillet over medium heat. Add the tomatoes and cook over medium-low heat, stirring occasionally, until the tomatoes begin to burst, about 10 minutes. Add the garlic and cook until fragrant, about 1 minute.

Squeeze as much liquid as possible out of the thawed kale. Spread the kale in a single layer in the bottom of the prepared baking dish. Top with the breakfast sausage, tomatoes, and par-baked Tater Tots. Pour the egg mixture over the top and sprinkle with the cheese. Use a spatula to gently press the layers down so the egg mixture soaks through. Bake for about 50 minutes, or until the eggs are just set and the top is beginning to brown. Let cool for 10 minutes before serving.

MAKE AHEAD: Assemble the casserole through the layering step, cover tightly with foil, and refrigerate overnight. When ready to bake, remove the foil and proceed with the recipe as directed.
