She, unlike her sister Hedvig Lovisa Pasch (1744-1796) was tutored explicitly because she displayed early talent for the work.

Ulrika Pasch was therefore, after the death of her mother in 1756, employed as a housekeeper in the house of her maternal aunt's widower, the goldsmith Gustaf Stafhell the Elder.

By the time of her brother's return to Sweden in 1766, she was said to have supported the family for a period of ten years.

In 1766, her brother Lorens Pasch the Younger returned to Stockholm, and from that point on, the two siblings worked together.

Pasch had an active and successful career until her death, and was frequently hired by members of the royal court and aristocracy.

Pasch was the only female who was made a member that year[2] a recognition which seem to have been considered to be well deserved within the academy.

Ulrika Pasch is portrayed in the novel Pottungen (Chamber pot child) by Anna Laestadius Larsson from 2014, where she, alongside Anna Maria Lenngren, Ulrika Widström, Jeanna von Lantingshausen, Marianne Ehrenström and Sophie von Fersen, becomes a member in a Blue Stockings Society organized by Hedvig Elisabeth Charlotte of Holstein-Gottorp, and the fictitious Rower woman Johanna is hired as a nude model by her.
