Step-by-Step Instructions

Step 1 — Prepare the Chicken

Start by cutting 1.5 pounds of boneless, skinless chicken breasts into bite-sized cubes. Season generously with salt, black pepper, and garlic powder.

Heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Cook the chicken until golden brown and cooked through, about 6–8 minutes. The internal temperature should reach 165°F for safe consumption.

Step 2 — Sauté the Vegetables

In the same skillet, add 1 diced onion, 2 minced garlic cloves, and 2 sliced celery stalks. Sauté for 4–5 minutes until softened and fragrant.

Add 1 cup of sliced mushrooms and cook for another 3–4 minutes until they release their moisture and begin to brown.

Step 3 — Create the Creamy Sauce

Sprinkle 3 tablespoons of all-purpose flour over the vegetables and stir constantly for 1 minute to cook out the raw flour taste.

Gradually whisk in 2 cups of chicken broth and 1 cup of heavy cream. Bring to a simmer, stirring frequently, until the sauce thickens enough to coat the back of a spoon.

Step 4 — Combine Casserole Ingredients

Return the cooked chicken to the skillet along with 1 cup of frozen peas and carrots, 1 teaspoon of dried thyme, and ½ cup of sour cream.

Stir everything together until well combined. Taste and adjust seasoning with additional salt and pepper if needed.

Step 5 — Prepare the Topping

In a medium bowl, combine 2 cups of crushed buttery crackers (such as Ritz) with ½ cup of melted butter and ¼ cup of grated Parmesan cheese.

Mix until the crumbs are evenly moistened and the mixture resembles coarse sand.

Step 6 — Assemble the Casserole

Transfer the chicken and vegetable mixture to a 9×13-inch baking dish, spreading it into an even layer.

Sprinkle the cracker topping evenly over the entire surface, covering all the creamy chicken mixture beneath.

Step 7 — Bake to Perfection

Bake in a preheated 375°F oven for 25–30 minutes until the filling is bubbly around the edges and the topping is golden brown.

For extra crispiness, broil for the final 1–2 minutes, watching carefully to prevent burning.

Step 8 — Rest and Serve

Remove the ULTIMATE Chicken Casserole from the oven and let it rest for 5–10 minutes before serving. This allows the sauce to thicken slightly for perfect serving consistency.

Garnish with fresh chopped parsley if desired. The casserole should be served hot with the creamy interior and crispy topping creating the ultimate texture contrast.

Healthier Alternatives

Customize your ULTIMATE Chicken Casserole with these simple ingredient swaps to match your dietary needs while keeping the comforting flavor.

• Ground turkey or chickpeas — Use ground turkey for a leaner protein or mashed chickpeas for a plant-based alternative; both absorb the savory seasonings well.
• Cauliflower rice or zucchini noodles — Replace traditional rice or pasta with cauliflower rice or spiralized zucchini for a lower-carb, veggie-packed version.
• Coconut milk or unsweetened almond milk — Swap dairy cream or milk with coconut milk for richness or almond milk for a lighter, dairy-free creaminess.
• Gluten-free breadcrumbs or almond flour — Use gluten-free breadcrumbs or finely ground almond flour for the topping to keep the crunch without gluten.
• Low-sodium broth and reduced-sodium cheese — Choose low-sodium chicken broth and reduced-sodium cheese to cut salt while maintaining deep, savory notes.
• Greek yogurt instead of sour cream — Substitute sour cream with plain Greek yogurt for extra protein and tang without sacrificing creaminess.
• Nutritional yeast or vegan cheese — For a dairy-free, cheesy flavor, stir in nutritional yeast or your favorite meltable vegan cheese alternative.
• Extra vegetables like spinach or mushrooms — Boost fiber and nutrients by adding chopped spinach or sautéed mushrooms, which blend seamlessly into the casserole.

Common Mistakes to Avoid

• Mistake: Using raw chicken directly in the casserole. Fix: Pre-cook chicken to 165°F (74°C) to ensure food safety and prevent a watery dish.
• Mistake: Overloading with creamy soups, making it greasy. Fix: Balance with low-sodium broth and a splash of lemon juice to cut richness.
• Mistake: Skipping the seasoning of each component layer. Fix: Season the chicken, sauce, and vegetables separately for depth in every bite.
• Mistake: Undercooking aromatics like onions and garlic. Fix: Sauté until fragrant and translucent to sweeten their flavor in the ULTIMATE Chicken Casserole.
• Mistake: Using soggy or overly soft toppings like breadcrumbs. Fix: Toast toppings separately and add just before baking for a crisp, golden finish.
• Mistake: Baking at too high a temperature, causing burnt edges. Fix: Bake at 350°F (175°C) covered for even heating, then uncover to brown.
• Mistake: Not letting the casserole rest after baking. Fix: Allow 10–15 minutes for the sauce to thicken and flavors to meld beautifully.
• Mistake: Overmixing ingredients, breaking down textures. Fix: Gently fold in tender components like pasta or veggies to maintain integrity.
• Mistake: Ignoring acid balance, resulting in a flat taste. Fix: Add a touch of vinegar or fresh herbs at the end to brighten the overall profile.

Storing Tips

• Fridge: Store your ULTIMATE Chicken Casserole in an airtight container in the refrigerator for up to 3-4 days.
• Freezer: For longer storage, freeze the casserole in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.
• Reheat: Reheat portions in the oven at 350°F (175°C) until the internal temperature reaches 165°F (74°C), or microwave until steaming hot.

Always ensure your ULTIMATE Chicken Casserole is cooled to room temperature before storing to maintain food safety and quality.
