Make Ahead Breakfast Casserole: Step-by-Step Guide

Ready to get cooking? Follow these steps to create your own Make Ahead Breakfast Casserole:

Step 1: Preheat Your Oven

Begin by preheating your oven to 350°F (175°C). This ensures that your casserole will cook evenly.

Step 2: Brown the Sausage

In a large skillet over medium heat, add the pork breakfast sausage. Cook until browned, breaking it up with a spatula as it cooks. This should take about 5-7 minutes.

Step 3: Add Vegetables

Once the sausage is fully cooked, add the chopped red onion and diced fennel bulb to the skillet. Season with a pinch of the kosher salt. Sauté for another 5 minutes until the vegetables are softened.

Step 4: Incorporate the Spinach

Stir in the fresh baby spinach, cooking just until it wilts. This will take about 2 minutes. Remove the skillet from heat and allow the mixture to cool slightly.

Step 5: Whisk Eggs and Milk

In a large mixing bowl, whisk together the eggs, milk, the remaining kosher salt, and ground black pepper until well combined and frothy.

Step 6: Combine Mixtures

Gently fold the sausage and vegetable mixture into the egg mixture. Make sure everything is evenly distributed.

Step 7: Prepare the Baking Dish

Grease your baking dish with a little olive oil or cooking spray to prevent sticking. Pour the casserole mixture into the prepared dish, spreading it out evenly.

Step 8: Bake

Place the dish in the preheated oven and bake for 30-35 minutes, or until the eggs are set and the top is lightly golden. A knife inserted in the center should come out clean.

Step 9: Cool and Serve

Once done, remove the casserole from the oven and let it cool for a few minutes. Slice into squares and serve warm. This dish is perfect on its own, but you can also pair it with fresh fruit or a light salad for a complete breakfast experience.

Seasonal Spins

One of the best things about this Make Ahead Breakfast Casserole is its versatility. Here are some ideas to change things up with seasonal ingredients:

• Summer: Use zucchini, bell peppers, and fresh basil to celebrate the bounty of summer produce.

Insider Tips
