Creamy Chicken and Veggies Casserole
This rich make ahead casserole is topped with a crunchy, cheesy topping that is kind of like dumplings, but with more texture. Alfredo sauce, frozen vegetables, and precooked chicken make it easy. The last time I made it I used Havarti cheese instead of cheddar, and it was sublime.
Prep Time: 20 minutes
Cook Time: 45 minutes
Total Time: 1 hour, 5 minutes
Yield: 8 servings
Ingredients:
•1 onion, chopped
•1 tablespoon olive oil
•2 tablespoons flour
•1 teaspoon dried thyme leaves
•1/8 teaspoon pepper
•1/2 cup whole milk
•1 (16 ounce) jar four cheese Alfredo sauce
•2-1/2 cups chopped cooked chicken
•1 (16 ounce) package frozen broccoli, carrots, and cauliflower
•1-1/4 cups shredded sharp Cheddar or Havarti cheese
•1/3 cup grated Parmesan cheese
•1 cup flour
•1/2 teaspoon dried thyme leaves
•1/4 teaspoon baking powder
•1/4 cup butter, softened
•1/2 cup shredded sharp Cheddar or Havarti cheese
•1/4 cup grated Parmesan cheese
•1 egg
Preparation:
In heavy saucepan, cook onion in olive oil over medium heat until tender. Add flour; cook and stir 3 minutes. Add 1 teaspoon thyme leaves and milk; cook and stir until thick.
Remove from heat and add Alfredo sauce, chicken, 1-1/4 cups Cheddar or Havarti cheese, 1/3 cup Parmesan cheese, and the frozen vegetables; stir gently. Place in 2-1/2 quart casserole. Cover and refrigerate 8-24 hours.
When ready to eat, preheat oven to 375 degrees F. Place casserole, covered, in oven and bake for 25-30 minutes until warm. Meanwhile, in small bowl combine flour, 1/2 teaspoon dried thyme leaves, baking powder, 1/4 cup butter, 1/2 cup Cheddar or Havarti cheese, Parmesan cheese, and egg and mix with a fork until crumbly.
Uncover casserole and crumble this topping evenly over the top. Bake for 20-30 minutes longer, until filling bubbles and the topping is golden brown and crisp.
You can also bake the casserole right away. After you place the chicken mixture in the casserole dish, top with the crumbly mixture and bake in preheated 375 degrees F oven for 25-35 minutes until bubbly and brown
