TIPS FOR MAKING BARBECUE CHICKEN CASSEROLE

Spice it up: Do you like your food spicy? Add red pepper flakes to add heat to the dish.

Pasta: Do not overcook the pasta on the stovetop. Al dente is vital to keep the pasta from becoming mushy.

Don’t have any leftover chicken? Here’s the best way to bake BBQ chicken using boneless chicken breasts:

  • Pound the raw chicken so that each breast is approximately the same thickness.
  • Season chicken with BBQ Spice Rub.
  • Bake at 400 degrees for 18 minutes. Be sure the internal temperature of the chicken is at 165 degrees before removing from the oven.
  • Next, brush your favorite bbq sauce over each chicken breast.

Baking dish: Use a 9 x 13 casserole dish for this recipe.

Cheese: It’s always best to grate cheese over using shredded cheese that comes in a bag. Not only does it melt better, but you’ll also save money, and it tastes better because it doesn’t have any preservatives or chemicals.

Store leftovers properly: If you have any leftovers, store them in an airtight container in the fridge for up to 4 days.

Freezer: Store leftovers in an airtight container after they have cooled entirely for up to 3 months.
