You're going to love this Creamy Tomato Basil Skillet Chicken! It's all about the sauce over perfectly sauteed chicken. Plus it's surprisingly dairy free, gluten free, and Whole30!
Slice your 4 chicken breasts horizontally to create 8 thin breast cutlets. (If you have a smaller skillet you can leave the breasts whole. I like them thin to soak up more sauce and cook faster.)
Add olive oil to skillet. Heat to medium high heat.
Add chicken to hot pan. Sprinkle salt, pepper, and dried basil on top of each breast. Cook until browned, about 5 minutes. Flip chicken. Cook until remaining side of chicken is browned, about 5 minutes. (It can take less time if you're using smaller cutlets so keep an eye on them.)
Remove chicken from the skillet and set aside on a plate.
Add all sauce ingredients to blender. Blend until smooth.
Pour blended sauce into the pan. Add spinach and a handful of cherry tomatoes. Stir until spinach is mixed in with sauce. Add your chicken back to the pan. Reduce heat to medium low or low. Cover and simmer for 5 minutes so sauce is heated through and cherry tomatoes are softened.
To thicken sauce, turn off heat. Shake together 1 tablespoon arrowroot flour and 1 tablespoon cold water in a small jar. Pour flour slurry into the sauce and stir. Sauce will begin to thicken quickly as you stir. If you want an even thicker sauce, repeat steps with another 1/2 tablespoon arrowroot flour and 1/2 tablespoon water. (Be sure not to add the arrowroot flour directly to the sauce or you'll end up with clumps. It must be shaken with equal parts water before being added to sauce.) Sprinkle chopped fresh basil on top of chicken before serving.
Notes
Do not use any coconut milk other than canned unsweetened coconut milk. I get this question a lot. Canned coconut milk is thick and not as watered down as the kind you'll find in the refrigerated section of the store. I prefer Thai Kitchen (make sure it says unsweetened and does not say low fat) but there are other brands that work well too!Nutritional information is for 1 chicken breast plus 1/4 of the sauce. If you slice each breast in half and end up with 8 thin cutlets remember that 2 of those cutlets is the equivalent of 1 breast. If you only have 1 thin cutlet then you'll need to 1/2 the nutritional info.
