  • 2 cups broccoli florets
  • 2 tablespoons salted butter
  • 1 small onion, diced
  • 1 celery stalk, diced
  • 1 clove garlic, minced or pressed
  • 1 (10.5 ounce) can condensed cream of mushroom soup, not diluted
  • 2 tablespoons mayonnaise
  • teaspoon paprika
  • teaspoon dry mustard
  • Pinch of ground nutmeg
  • 1 ½ cups grated sharp cheddar cheese, divided
  • ¾ cup 2% or whole milk
  • 2 cups cooked long-grain white rice
  • 2 cups cooked, diced chicken
  • Kosher salt and black pepper
  • 15 Ritz crackers (about half of a sleeve), lightly crushed


  • Cook the broccoli for about 2 minutes in boiling water, just until crisp-tender. Drain and set aside.
  • Preheat oven to 350°F. Grease a 2-quart baking dish; set aside.
  • In a large skillet or Dutch oven, melt butter over medium-high heat. Add onion and celery; cook, stirring occasionally, until the onion is translucent, about 5 minutes. Add garlic; cook until fragrant, about 30 seconds.
  • Reduce the heat to a very low flame. Stir in soup, mayonnaise, paprika, dry mustard, nutmeg, 1 cup of the cheese, and milk. Cook, stirring constantly, until the cheese melts, about 2 minutes. Remove from heat.
  • Add cooked rice, chicken, and broccoli; stir to combine. Taste and season with salt and pepper, if necessary.
  • Transfer mixture to the prepared baking dish. Top with remaining ½ cup of cheese and crushed crackers.
  • Bake, uncovered, for about 25 minutes, or until the filling is hot and bubbly and the topping is lightly browned.
