Key Ingredients and Notes

How to Make Bisquick Sausage Egg Bake:
With simple ingredients, this recipe can be made in less than 1 hour. As always, the printable recipe card is below.
- The first step to make this easy cheesy bisquick breakfast casserole is to preheat the oven to 350 degrees Fahrenheit.
- Then you grease a 9×13 baking dish with butter or oil. I like to just use nonstick cooking spray. Then set this aside.
- In a large skillet add olive oil (or vegetable oil), chopped onions, and bacon bits over medium heat. Cook for 2-3 minutes until the onions are softened and the bacon bits are warm.
- Add the ground pork sausage, onion powder, salt and black pepper to the skillet. With a wooden spoon, separate the sausage and mix. Then cook 4-5 minutes, stirring occasionally.
The sausage may still have some pink color, but this is okay, it will finish cooking in the oven. - The rest of this recipe takes 4 simple steps. The first is to pour the sausage mixture into the prepared baking dish and set aside.
- In a large bowl mix together the following ingredients: Bisquick, milk, large eggs, and cheese. I like to use Colby Jack or cheddar cheese, but you can use your preferred type of shredded cheese.
- Gently pour egg mixture over the sausage crumbles. Sometimes I like to sprinkle a bit of mozzarella cheese over the top before baking.
- Bake in the preheated oven for a bake time of 28-30 minutes, or until the cheese is nice and golden brown to your liking.
Did You Know?
Shredded block cheese melts better when baking in the oven, verses pre-bought bags of shredded cheese. Well, now you know!
TIP: If the edges are starting to brown too fast, cover your casserole with aluminum foil to finish the cooking. It’s always best to check half-way through cooking and adjust accordingly.
When this bisquick breakfast casserole recipe is done, allow to cool while you get out the plates and utensils. Serve and enjoy!

Recipe Tips & Tricks
Optional Add-Ins
- One of the beautiful things about this perfect breakfast casserole recipe is the options for additions and substitutions. Add green onions, mushrooms or chopped bell pepper to the skillet.
- Swap the milk for cream, or add in a small amount of sour cream to help keep this savory breakfast casserole moist, especially for reheating.

What to Serve with Breakfast Casserole
I like to serve this savoury Bisquick Breakfast Casserole with a contrasting sweet side. Fruit salad, fruit yogurt or sliced fresh fruit (like oranges, berries, or melon) are good options.
Like all egg dishes, you can’t go wrong with more protein as well. Links of sausage and strips of bacon are a suggestion. You can also serve this with scones, muffins, banana bread or baking powder biscuits.
Toast with strawberry chia seed jam, hash browns, and tater tots makes wonderful sides for this best breakfast casserole recipe as well.
