Set the Instant Pot to sauté mode and heat the olive oil. Add the lamb stew meat and brown it on all sides for about 5 minutes.
Add the diced onion and minced garlic. Cook for 2 minutes until the onion starts to soften.
Stir in the cumin, cinnamon, coriander, and tomato paste. Cook for 1 minute to toast the spices.
Pour in the beef broth and add the chopped dates. Season with salt and pepper.
Secure the lid and set the Instant Pot to manual high pressure for 35 minutes. Allow a natural pressure release for 10 minutes, then quick release any remaining pressure.
Open the lid and give the stew a stir. Toast the slivered almonds in a dry skillet over medium heat for 2 minutes until lightly golden.
Ladle the stew into bowls and top each serving with the toasted almonds and chopped parsley.
