What You Will ❤️ About Cheesy Potatoes with Jarlsberg
I wanted to put a spin on Cheesy Potatoes! It’s got all cheesy sauciness of traditional but with a new flare from Jarlsberg cheese and red onions. If you’re not familiar with Jarlsberg cheese – it’s from Norway and is similar to Swiss cheese. The most popular recipe with Jarlsberg is their famous cheese dip!

Tips, Tricks & FAQs
Store leftovers in an airtight container (I like these glass ones) in the refrigerator for up to a week. You can freeze up to three months. Reheat in the microwave for 1-2 minutes, the air fryer at 275º for 5 minutes or the oven at 300º for 25 minutes.
Of course, reserve the melted butter and, in a small bowl, mix it with crushed Ritz crackers, potato chips or corn flakes and spread topping over the potato mixture before baking.
You could but I wouldn’t. Real butter is so much better!
Yes – make it the day before and cover with plastic wrap or aluminum foil. Refrigerate until ready to bake. If using a crunchy topping – leave that off until you put into the oven.
Yes – and no need to thaw them – you just might need to bake 5-10 minutes more.

Should you defrost the potatoes or mix them in frozen?
I just mixed them in frozen – they’ll thaw and bake in the oven.
