Pat the chicken thighs dry with paper towels, then cut into bite-sized pieces. Trim any excess fat/fatty pieces off of the chicken. Add the chicken to a large bowl and season with Italian seasoning garlic powder, onion powder, salt, and pepper. Toss until the chicken is evenly coated. 1 1/2 lbs Boneless Skinless Chicken Thighs2 tsp Italian Seasoning 1 tsp Garlic Powder1 tsp Onion PowderSalt and Pepper
Heat a large skillet over medium heat for about 3-4 minutes, then add a drizzle of olive oil. Add the chicken in a single layer. Cook for 3–4 minutes per side, or until the chicken is golden brown on the outside and cooked through. Work in batches if needed so the chicken sears instead of steams.
Remove the cooked chicken from the skillet and set aside on a plate.
Add the butter. Once melted, add diced onion and cook for 2–3 minutes, stirring occasionally, until softened and lightly golden. Use a wooden spoon to scrape up the browned bits from the bottom of the pan - this adds tons of flavor to the sauce. 4 tbsp Salted Butter1/2 Yellow Onion
Add the minced garlic, and Cajun seasoning. Stir constantly for 2 minutes, or until the garlic is fragrant and slightly browned. Be careful not to let the garlic burn. 6 cloves Garlic1 tsp Cajun Seasoning
Add the chicken back to the skillet and toss until every piece is coated in the garlic butter sauce.
Stir in the lemon juice and fresh parsley. Remove from the pan and sprinkle with parmesan cheese. 1 tbsp Lemon Juice1 tbsp Fresh Parsley3 tbsp Parmesan Cheese
