Instructions
Preheat oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with butter or cooking spray.
In a large skillet over medium heat, melt butter. Add diced onion and cook for 4-5 minutes until soft and translucent. Add minced garlic and cook for 1 more minute until fragrant. Remove from heat.
In a large mixing bowl, combine cream of mushroom soup, chicken broth, sour cream, garlic powder, salt, and pepper. Stir until smooth. Add the sautéed onion and garlic and stir to combine.
Add the bite-sized chicken pieces, uncooked wild rice blend, and frozen peas to the sauce mixture. Stir well until everything is evenly distributed.
Pour the mixture into the prepared baking dish and spread into an even layer. Sprinkle shredded cheddar cheese evenly over the top.
Cover the dish tightly with aluminum foil. Bake covered for 60 minutes. Do not lift the foil during this time.
Carefully remove the foil. Bake uncovered for an additional 10-15 minutes until the cheese is melted, bubbly, and golden at the edges. The rice should be tender and chicken cooked through.
Let the casserole rest for 5-10 minutes before serving. Scoop into bowls or onto plates and enjoy.
Notes
Wild rice blend: Use a true wild rice blend that includes long-grain, red rice, and wild rice for the best nutty texture. Do not use instant rice as it will become mushy.
Don't skip the foil: The steam created by covering with foil is essential for cooking the uncooked rice through. Skipping this step will leave you with crunchy, undercooked rice.
Uniform chicken pieces: Cut chicken into even bite-sized pieces so everything cooks evenly. Pieces that are too large may still be raw when the rest of the casserole is done.
Rotisserie chicken shortcut: To save time, use 3-4 cups of shredded rotisserie chicken. Reduce the covered baking time to 40-45 minutes since the chicken just needs to heat through.
Make-ahead option: Assemble the full casserole up to 24 hours in advance, cover tightly, and refrigerate unbaked. When ready to bake, add 10 extra minutes to the covered baking time.
Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days. The flavors deepen overnight, making leftovers even better.
Reheating: Reheat covered with foil at 350°F for 20-25 minutes. For individual portions, microwave on medium power in 90-second intervals, stirring in between.
Freezer-friendly: Freeze portions in freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator before reheating.
Lighter version: Substitute plain Greek yogurt for the sour cream to reduce fat while keeping the tangy creaminess.
Add vegetables: Stir in diced carrots, celery, or sliced zucchini alongside the peas for extra nutrition and color.
