Season the chicken breasts and shrimp with Cajun seasoning, brown sugar, and kosher salt.
Drizzle with olive oil.
Heat a large skillet over medium-high heat.
Add 1 tablespoon of olive oil and 1 tablespoon of butter.
Once the skillet is hot, sear the chicken for 6-8 minutes.
Ensure it reaches an internal temperature of 165°F.
Remove from the pan and set aside.
In the same skillet, melt remaining butter with minced garlic.
Add shrimp and sear until pink and opaque.
This should take about 3-5 minutes.
In a separate pot, add chicken broth, water, and some kosher salt.
Bring to a boil, then add red potatoes.
Simmer until tender, then strain and reserve a cup of broth.
