This is a family favorite recipe and I make it for dinner, or brinner as the boys call it, a lot. Breakfast casseroles are super convenient to make for tailgating if you have an early game and, of course, for Christmas morning, weekends, or when you have overnight guests!

I have two goals with it comes to cooking and eating. I want something easy to prepare and I want to eat with my family.

Overnight Breakfast Sausage Casserole makes a time-saving breakfast or dinner. You can simply make it 6 to 8 hours ahead of time, then bake when you’re ready.

One of the ingredients that also help in the meal prep of this casserole recipe is using Bacon Bits. instead of cooking and crumbling bacon. Although, you can totally do that if you prefer. Real bacon bits cuts down on the prep time.

I do find that prepared bacon bits are a little saltier than cooking bacon myself. With this in mind, you may want to hold off adding salt to the casserole. Each person can add it, if needed.

Any ‘day old’ bread will work for this recipe. I used old hotdog buns. As well, I ‘eyeball’ the amount and put a layer in a 7×11-inch casserole dish.

eat with my family

As I mentioned above easy meals and eating with my family are important to me. I’m a big advocate of eating meals together as a family and my goal to eat at least 4 meals a week together. It’s been relatively easy so far for us to do that. I know as the boys get older, it’ll become more difficult. It’s important, as studies have should, so I encourage you to eat family meals together… and of course, make this casserole for a meal!

Family meals eaten at home have been proven to benefit the health and wellness of children and adolescents, to fight obesity, substance abuse and to make families stronger – creating a positive impact on our communities and our nation as a whole

  1. I am hoping to make this and freeze it for my postpartum season. Is that recommended? If so, do I bake it first or freeze it first?

    1. I would bake it then freeze. You can even freeze in individual serving sizes then pop it in the microwave or oven to reheat.

  4. Thank you so much for sharing this recipe. Any chance that almond milk would work instead of cow’s milk?
