Thank you for writing.
You certainly can plant them outside, usually in mid to late October. https://www.bulbblog.com/flowering-bulbs-in-pots-after-blooming/
Note Minnesota is zone 3-5, but you can find your exact zone here (save this) https://www.gardeningknowhow.com/planting-zones/minnesota-planting-zones.htm
Now here is the sad news: Tulips may not keep blooming year after year. https://www.gardeningknowhow.com/ornamental/bulbs/tulips/tulips-bloom-every-year.htm The good news is that you can use your potted plants to start beds. Start slow, twenty bulbs and soon you might go crazy and put in a couple of hundred bulbs in the fall
Best of luck
