No reviews

A wholesome twist on a classic comfort dish, this Chicken and Wild Rice Casserole is creamy, cozy, and made with fresh ingredients — no canned soup required.

There’s something undeniably comforting about a warm casserole coming out of the oven. This version keeps everything you love about the classic — creamy texture, hearty rice, melted cheese — but swaps processed shortcuts for simple, real ingredients.

Nutty wild rice forms the base, tender chicken adds protein, and sautéed onions and mushrooms bring depth of flavor. A touch of sour cream and cheddar cheese ties everything together into a rich, satisfying bake that feels nostalgic yet fresh.

It’s the kind of dinner that fills your kitchen with warmth and your table with happy faces.

Ingredients

Scale

  • 1 tablespoon + 1 teaspoon olive oil, separated

  • 1 small onion, diced

  • 1 cup sliced mushrooms (cremini or white)

  • 1 teaspoon kosher salt, divided

  • 1/2 teaspoon garlic powder

  • 1 pound boneless, skinless chicken breasts (about 2), cut into 1/2-inch pieces

  • 1/2 cup sour cream

  • 1 cup shredded cheddar cheese, plus extra for topping

  • 3 cups cooked wild rice (see below)

For the Wild Rice

  • 1 cup wild rice

  • 4 cups water

Instructions

Step 1: Cook the Wild Rice

Preheat oven to 400°F.

In a large saucepan, combine wild rice and water. Bring to a boil over high heat, then reduce to a simmer. Cover and cook for about 50 minutes, or until rice is tender.

Drain any excess liquid and transfer the cooked rice to a large mixing bowl.

Step 2: Sauté the Vegetables

While the rice cooks, heat 1 tablespoon olive oil in a large sauté pan over medium heat. Add the diced onion and cook for 2 minutes.

Add the sliced mushrooms and 1/2 teaspoon salt. Cook for another 4 minutes, until mushrooms are tender and onions are translucent.

Remove the mushroom mixture from the pan and set aside.

Step 3: Cook the Chicken

In the same pan, heat the remaining teaspoon of olive oil. Add the diced chicken, garlic powder, and remaining 1/2 teaspoon salt.

Cook for about 3 minutes, or until the chicken is cooked through.

Step 4: Assemble the Casserole

Add the sautéed vegetables, cooked chicken, sour cream, and shredded cheddar cheese to the bowl with the wild rice. Stir until well combined.

Transfer the mixture to an 8×8-inch baking dish and sprinkle with additional shredded cheese on top.

Step 5: Bake

Bake for 20–25 minutes, or until heated through and bubbly.

Serve warm.

Notes

  • Make It Lighter: Use Greek yogurt in place of sour cream for a protein boost.

  • Add Greens: Stir in fresh spinach or kale before baking for extra nutrients.

  • Meal Prep Friendly: Assemble ahead of time and refrigerate. Add 5–10 minutes to baking time if cooking straight from the fridge.

  • Freezer Friendly: Freeze unbaked casserole tightly covered for up to 2 months. Thaw overnight before baking.

  • Cheese Swap: Try Monterey Jack or Gruyère for a flavor variation.
