Turn Instant Pot to saute. While it heats, dice onion and mince garlic.
Add oil, then onion, tomato paste, and paprika. Cook for a minute, then add garlic and immediately turn off Instant Pot. Stir periodically until onion softens.
Add chicken stock, lemon juice, and chicken. Close lid and set vent to seal. Cook for 9 minutes.
1 cup chicken stock, 1/4 cup lemon juice, 2 pounds chicken
After it finishes cooking, do a natural pressure release for 10 minutes. While you wait, add cornstarch to a small bowl with water and whisk.
3 tablespoons cornstarch, 2 tablespoons cold water
Carefully open the lid. Remove chicken to a plate or cutting board. Add cornstarch to the IP and turn the pot to saute. Stir and let it thicken for a couple minutes.
Turn to warm, and add half and half and salt, then chicken and stir gently to coat with sauce.
1/2 cup half and half, 1 teaspoon salt
Taste to ensure you have the right balance and add more lemon, cream, or salt to fit your preference. Serve immediately over rice.
Notes
If you have extra thick breasts, add a minute or two to the cooking time, but most chicken cooks just fine at nine minutes.
One great thing about the Instant Pot is that you can use frozen meat and not only fresh. If you plan to use frozen chicken, follow the same instructions, but set the Instant Pot to cook for 16 minutes instead. You don't want to know how many nights that's saved me!
