Easy Cheesy Chicken Broccoli Rice Casserole

Last Tuesday night when soccer practice ran late and homework still needed checking, this cheesy chicken broccoli rice casserole saved the day again. I had prepped it during oliver's afternoon playdate, popped it in the fridge, and just slid it into the oven when we got home. By the time everyone had changed and settled in, dinner was bubbling away with that irresistible aroma that always brings my family running to the table without being called twice.

Why You'll Love This Cheesy Chicken Broccoli Rice Casserole

This Cheesy Chicken Broccoli Rice Casserole has saved dinner at our house on more nights than I can count. It first came into heavy rotation about two years ago, during that chaotic stretch when oliver started soccer, I took on extra work projects, and somehow we were still expected to eat actual meals instead of just grabbing granola bars in the car between activities.

I remember the first time I served it - it was a Thursday night, oliver had homework spread across the kitchen table, and I had exactly 30 minutes to get something on the table before his bedtime routine needed to start. I threw together what ingredients we had, crossed my fingers, and hoped for the best. Not only did oliver clean his plate without a single "what's this green stuff?" question, but my husband took leftovers for lunch the next day without being prompted. In our house, that's the equivalent of a standing ovation.

2. Cook rice according to package directions if you don't have leftovers
3. Cut broccoli into bite-sized florets
4. Blanch broccoli for 1 minute in boiling water, then immediately plunge into ice water (this keeps it bright green!)

Assembly:

2. Pour the creamy sauce over everything and fold together until evenly coated

Baking:

1. Bake uncovered for 25-30 minutes until bubbly around the edges

Grandma's Secret Fix Passed Down for Generations (Now It's Yours)

My grandmother Ruth wasn't exactly known for her culinary skills. The family joke was that her specialty was burning toast, and we still tease my dad about surviving childhood on her infamous "mystery stews." But there was one dish - just one - that had everyone clamoring for seconds: her chicken and rice casserole. Last Thanksgiving, as I helped her in the kitchen while everyone else watched football, she finally shared her secret.

"Come here, honey," she said, looking over her shoulder to make sure no one else was within earshot. "I've never told anyone this, not even your mother." She was making her casserole, methodically layering rice, broccoli, chicken, and that amazing sauce, when she paused before putting it in the oven.

From her apron pocket, she pulled a small flask. I raised my eyebrows, and she laughed. "It's not what you think!" Inside was chicken broth, but not just any broth. She explained she'd been reducing store-bought broth on the stove until it was concentrated, almost like a demi-glace.
