The days are getting longer and it’s getting harder and harder for me to stay indoors and want to cook. Although it’s not quite warm enough for me to stand outside in my winter coat and fire up the grill either. Insert my BFF, the slow cooker!

What I love about the slow cooker, is the set it and forget it mindset. Most recently I tried my hand at Slow Cooker Macaroni and Cheese and it blew the whole family away. I wasn’t sure how it was going to turn out as I didn’t want the noodles to get mushy, but it worked beautifully!

I had the same thinking with this slow cooker version of the classic Hash Brown Casserole. Would the hash browns turn into a soupy mess, having the family scrambling for an alternative breakfast? Answer – not at all.

What I also love about the slow cooker is the evenly browned edges, all around the outside, which happen to be my favorite. This Slow Cooker Hash Brown Casserole has lots of them. From the cheese, potatoes and corn flakes, there’s crispiness all over this dish. And it couldn’t be simpler to put together.

MIX. You start by mixing all of your ingredients into a bowl.

SLOW COOK. Then pour into a lightly greased slow cooker and set that baby to go on HIGH for 2 hours and 30 minutes.

CRUNCHY TOP. Next, melt some butter and mix with some corn flake cereal and then pour on top of the casserole. Cook for an additional 30 minutes. If you don’t have corn flakes, you can also used crushed crackers or even Panko for some crunch.

Now you’ve got yourself the creamiest, crunchiest, cheesiest hash brown casserole I ever did have. Beyond simple!

Recipe Notes

FREEZING. Wrap the dish in plastic wrap or foil and store in the freezer for up to 2 months. Thaw completely before baking. Bake in the oven at 350 until heated through.

REHEATING. Reheating your hash brown casserole is a cinch! Just preheat your oven to 375 degrees and reheat for 7-10 minutes or until it’s warmed through. Or you can reheat in the microwave until heat thoroughly. The time will vary depending on your microwave.

This Slow Cooker Hash Brown Casserole is the tastiest and easiest casserole I’ve ever made. It would be an amazing dish to serve for your Easter Sunday brunch. It would also be great to make after Easter dinner when you have leftover ham.

Either way, put this into your permanent breakfast rotation, you won’t be sorry and your family will love you even more for it!
