How to Make Whole30 Jalapeño Buffalo Chicken Casserole
This straightforward casserole comes together in simple steps. Follow this process for perfect results every time:
Step 1: Prep Your Ingredients
Start by preheating your oven to 400°F. Gather all chopped vegetables and cooked shredded chicken in a large mixing bowl. While the oven heats, this gives time for flavors to blend slightly before baking.
