Bisquick Breakfast Casserole is a modern hero in plainclothes. It’s Saturday morning, the rooster has crowed, and your family has begun to prowl around the kitchen like ravenous zombies from the latest thriller. We’ve all been there. Bellies are growling, but you can only seem to locate a few random ingredients:  frozen hash browns, eggs, veggies, milk, and … Bisquick? Bisquick Breakfast Casserole, to the rescue!

This marvelous dish is so simple to whip together, and it will keep those stomachs from grumbling until the next regularly scheduled mealtime. It does take a solid 45 minutes to bake, however, so it’s best to get a head start on the zombies! Once they have had their fill, though, all they will remember is the gooey cheese, savory pork sausage, and flavorful veggies, and any tardiness will be forgiven and forgotten.

What Ingredients Do You Need To Make Bisquick Breakfast Casserole?

Some people make Bisquick breakfast casserole without hashbrowns, but I love the extra texture that they provide! If you really can’t abide hashbrowns, you could make your breakfast casserole with bread slices instead. Breakfast casserole with biscuits lining the bottom of the tray is another common alternative.

In addition to 3 cups of frozen hashbrowns, my recipe calls for 24 ounces of bulk pork sausage (flavored ground pork that typically comes in a cylindrical tube), and 4 large eggs. You will also need half a cup of chopped onion, a cup of freshly chopped red bell pepper, a couple of cups of grated sharp cheddar, some Bisquick, milk, salt, and pepper.  

How To Make Bisquick Breakfast Casserole?

Here’s how to make a breakfast casserole: cook the sausage, onions, and pepper in a skillet, then mix them with cheese and hashbrowns in a baking dish. Pour the Bisquick, milk, egg, and seasoning blend over top, then bake the casserole until it sets! For an added bonus, melt some extra cheese on top. Now you have a delicious Bisquick breakfast quiche!

Recipe Notes For Bisquick Breakfast Casserole:

Meat variations: If pork sausage isn’t a favorite, you can also make this Bisquick breakfast casserole bacon style, or try your Bisquick breakfast casserole with ham instead. For those who are vegetarian, vegan, or have protein restrictions, Bisquick egg casserole no meat is another possibility.  

Bisquick: What is it, anyway? We know it’s a convenience baking mix, with ingredients along the lines of flour, salt, and baking soda, but where did it come from? General Mills has the abbreviated story here. Bisquick is the brainchild of an innovative chef who worked a San Francisco bound train in 1930.

How To Make Ahead Of Time: Good news: this recipe doubles as a Bisquick make-ahead breakfast casserole! It keeps in the fridge for 3 – 4 days and in the freezer for 2 – 3 months, according to the FDA.

How To Freeze Bisquick Breakfast Casserole:For best results, use an airtight, freezer safe container. You might want to use an aluminum baking dish and lid so the casserole doesn’t hold your good dishes hostage for months. Let the casserole cool down from baking temperatures (on the counter for under two hours, then in the fridge), label it, and pop it in the freezer! Thaw in the refrigerator overnight before you plan to serve. I recommend reheating in the oven to preserve the dish’s texture.

What To Serve With Bisquick Breakfast Casserole: Breakfast casseroles go great with something slightly sweet, like fruit salad or yogurt parfait! A simple plate of sliced watermelon, apples, or oranges will also do the trick.
