    Now I’ll walk you through the detailed recipe with extra tips…

    Prepped ingredients for Egg and Sausage Christmas Breakfast Casserole Sip Bite Go
    1. Use butter to grease a 9×13 baking dish and set it aside.
    2. Add onion and butter to a large skillet pan on the stove on medium-high heat.

      Stir regularly for about 5 minutes, until the onion is translucent – you want it to be just starting to turn brown. 
    Browning pork sausage Sip Bite Go
    1. Push the cooked onion to one edge of the pan. Add pork sausage to the other half of the pan, breaking it up with a spatula so it begins to brown in crumbles.

      Regularly stir both the sausage and onions on their own sides of the pan for about 5-10 minutes, until the sausage is browned. In the final minute you can combine the sausage and onions together.

      Turn off the heat of the skillet and drain any excess oil from the pan if desired.
    2. Toss cooked onions and pork sausage with maple syrup. Your kitchen will smell so good right now!
