Preheat your oven to 350 degrees Fahrenheit. This is crucial for achieving that perfect bake. A hot oven will help the casserole puff up beautifully.
In an oven-proof frying pan, cook the sausage over medium heat. As it cooks, break it up into smaller pieces. You’re looking for a nice golden color. Once the pink is gone, scoop it out and set it aside.
Now, if you want to ensure nothing sticks, spray the pan with non-stick spray. This step isn’t mandatory, but it can save you from any sticky situations later.
Return the cooked sausage to the pan and sprinkle the cheddar cheese over the top. The cheese will melt beautifully during baking and create a delicious crust.
In a separate bowl, whisk together the eggs, biscuit mix, and milk. Make sure to beat slightly and add salt and pepper to taste.
Pour this mixture over the sausage and cheese in the pan. Ensure it’s evenly distributed so every bite is flavorful.
Place the pan in the preheated oven. Bake for 30 to 45 minutes, depending on your pan’s size. If using a skillet, expect it to be around 40 minutes. You’ll know it’s done when the center is firm and no longer jiggly.
Once baked, let it cool for a few minutes before slicing. This helps everything set and makes serving easier.
Serve warm, and watch your friends and family enjoy each bite!
