An easy way to make a copycat version of Chili’s cajun chicken and penne. It tastes soooo good and costs a fraction of the price you’d pay at a restaurant.


  • 2 boneless, skinless chicken breasts (around 1 1/2 pounds)
  • 2 Tbsp olive oil, divided
  • 1 Tbsp cajun seasoning
  • 3 large garlic cloves, minced
  • 1 3/4 cups chicken broth
  • 8 ounces penne pasta
  • 2 Tbsp butter
  • 1/3 cup heavy cream, warmed
  • 1/2 tsp fresh lemon zest (or more to taste)
  • 1/4 cup parmesan cheese
  • 2 roma tomatoes, diced


  1. Turn Instant Pot to sauté setting.
  2. Add chicken, 1 Tbsp of olive oil and the cajun seasoning to a container with a lid. Shake to coat thoroughly.
  3. When display says HOT add in the remaining 1 Tbsp of olive oil. Add the coated chicken into the pot and let sit and brown on one side for 2 minutes and then flip over and brown on other side for 2 minutes. Move chicken to a plate. 
  4. Add the garlic into the pot and sauté for about 30 seconds. Stir in the broth and scrape bottom of pot so that nothing is sticking. Turn off sauté setting.
  5. Add the penne into the pot. Add the butter and chicken and place on top of the penne.
  6. Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 4 minutes. When time is up let the pot sit for 10 minutes and then move valve to venting. Remove the lid.
  7. Move chicken to a cutting board.
  8. Stir in the warm cream, lemon zest and parmesan cheese. 
  9. Slice the chicken across the grain. 
  10. Add a scoop of the penne to a bowl, top with some sliced chicken, add some tomatoes to the top and garnish with parsley, if desired. If needed add a few dashes of cajun seasoning, to taste.
