A cozy, easy slow cooker casserole combining tender chicken, cheesy tortellini, and fresh basil pesto for a comforting and flavorful meal perfect for busy weeknights or lazy weekends.
Do not add tortellini at the start to avoid mushiness; add it late in cooking. Use quality pesto for best flavor. If casserole is too thick after adding tortellini, add a splash of chicken broth. For extra gooeyness, sprinkle mozzarella on top and broil 2-3 minutes before serving. Leftovers keep well for 3 days refrigerated; add broth when reheating to maintain creaminess. Can be made dairy-free or gluten-free with substitutions.
