Step-by-Step Instructions
Step 1: Preheat oven to 350°F. Grease a 9x13 inch pan. Cook sausage in a skillet, breaking it up as it browns (a mix and chop kitchen tool works great!). Drain and set aside. Sauté onions and peppers in the same skillet until softened. Return sausage to the pan and combine. Let the mixture cool while you prepare the eggs.
Step 2: In a bowl, whisk together eggs, sour cream, and milk until well combined. Add the sausage mixture and stir. Mix in most of the cheese, reserving about ½ cup.
Baking Instructions
Step 3: Pour into prepared dish, top with remaining cheese, and bake 40-45 minutes until set. Let cool slightly before serving.

Recipe FAQ's

A runny center in your breakfast casserole is likely due to too much liquid in the egg mixture or underbaking. Make sure you have the proper ratio of bread, eggs, and milk to ensure the casserole sets properly. Reduce liquids next time and ensure the center is fully set by using a knife or toothpick to check for doneness.
Whether you bake a casserole covered or uncovered depends on the specific recipe and desired outcome. Covering helps with even cooking and moisture retention, while uncovering allows for browning and crisping.

So yummy!! I'm not a huge sausage fan so we did 1 lb sausage and 1lb hash browns. I also added a ranch packet for extra flavor. Just an FYI it took more like 50 minutes in the oven after refridgerating overnight. It was easy and delicious!

I'm glad you were able to make the recipe your own. Did you allow the casserole to come to room temperature before baking? Also, it might have taken longer for you because you added hashbrowns, which the recipe does not call for. Thank you for leaving a 5-star review!
