Ingredients You’ll Need

All the ingredients for this recipe are straightforward and pantry-friendly, yet each one plays a crucial role in bringing together that rich, comforting texture and savory depth that makes this casserole so irresistible.

Cooking spray: Keeps the casserole dish from sticking and makes cleanup easier.
1 (10.5-ounce) can cream of chicken soup: Adds creamy richness and a luscious base flavor.
1 (10.5-ounce) can cream of celery soup: Brings subtle herbaceous notes and smoothness to the sauce.
1 1/2 cups water: Moistens the rice and blends all the ingredients perfectly.
2 cups quick-cooking rice: Cooks perfectly under the foil, absorbing all the savory flavors while staying tender.

1 (2-ounce) package onion soup mix, divided: This seasoning mix élevates the dish with its classic onion and herb punch.
4 (7-ounce) boneless, skinless chicken breasts, patted dry: The star protein that stays juicy and tender thanks to the no-peek method.

2 teaspoons chopped fresh chives, optional: A fresh, mild onion flavor for garnish that adds an appealing pop of green.

How to Make No-Peek Chicken Casserole with Creamy Rice and Vegetables Recipe

Step 1: Preheat the oven and prepare the baking dish

Start by setting your oven to 350°F (175°C) and positioning a rack in the middle. This even heat placement ensures your casserole cooks uniformly. Then, spray a 9×13-inch baking dish with cooking spray—this step may seem small but it makes retrieving your casserole after baking so much easier and prevents any sticking.

Step 2: Create the creamy base mixture

In your prepared dish, whisk together the cream of chicken soup, cream of celery soup, and water until completely smooth. This creamy base is where the heart of your comforting casserole lives. Stir in the quick-cooking rice, frozen peas and carrots, and half of the onion soup mix (about 4 tablespoons). You want every grain of rice to be coated with the savory mixture, setting the stage for that dreamy creamy texture after baking.

Step 3: Season and add the chicken

Give your chicken breasts a simple but essential rub of kosher salt and freshly ground black pepper. This seasoning penetrates the meat gently and enhances its natural flavor. Carefully nestle each chicken breast right into the rice and vegetable mixture, making sure they’re evenly spaced for even cooking.

Step 4: Top with remaining seasoning and cover tightly

Sprinkle the remaining half of the onion soup mix evenly over the chicken breasts. Cover your baking dish tightly with aluminum foil—this step is pivotal for the “no-peek” magic. The foil locks in moisture, allowing the chicken to steam and the rice to become perfectly creamy without you needing to open the oven door and check.

Step 5: Optional make-ahead preparation

If you want to save time on the day you plan to eat this, you can assemble the entire casserole up to 12 hours ahead. Simply keep it covered in the refrigerator, then remove it 30 minutes before baking so it comes to room temperature and cooks more evenly.

Step 6: Bake until juicy and tender

Pop the covered casserole into your preheated oven and bake it for 50 to 60 minutes. Use an instant-read thermometer to check that the chicken reaches 160°F internally; it will continue to rise to 165°F while resting. At this point, the rice should be tender and creamy, perfectly soaking up all those savory flavors.

Step 7: Rest, fluff, and finish

Once baked, remove the foil and let the casserole rest uncovered for 5 minutes. This resting time helps the juices redistribute in the chicken and allows the rice to settle. Afterward, gently fluff the rice with a fork to separate the grains, then sprinkle on fresh chopped chives if you like a fresh herbal touch before serving.

How to Serve No-Peek Chicken Casserole with Creamy Rice and Vegetables Recipe

Garnishes

Fresh chives sprinkled on top add a lovely pop of green color and subtle onion flavor that cuts through the creaminess beautifully. You can also add a light dusting of paprika or a handful of chopped parsley to brighten the presentation and add layers of flavor.

Side Dishes

This casserole is quite a hearty main dish on its own, but pairing it with a crisp side salad or steamed green beans provides a refreshing contrast and additional nutrients. A simple vinaigrette salad with lemon or balsamic dressing complements the creamy richness perfectly.

Creative Ways to Present

For an inviting family-style meal, serve the casserole straight from the baking dish on the table. Or, scoop individual portions onto plates and garnish with extra chopped herbs and a wedge of lemon to brighten the savory flavors. For casual gatherings, consider serving it in mini ramekins for single servings that look charming and gourmet.

Make Ahead and Storage

Storing Leftovers

Any leftovers should be stored in an airtight container and refrigerated promptly. This casserole will stay fresh and delicious for up to 3 days, making it perfect for quick lunches or dinners later in the week.

Freezing

If you want to tuck some away for longer, you can freeze portions of this casserole. Use freezer-safe containers or heavy-duty freezer bags, making sure to cool completely before sealing. It’s best enjoyed within 2 months for optimal flavor and texture.

Reheating

To reheat, thaw frozen portions in the refrigerator overnight. Warm leftovers gently in the oven at 325°F until heated through, or microwave individual servings with a damp paper towel over the top to keep moisture in. Fluff the rice again before serving for that perfect texture.

FAQs

Can I use brown rice instead of quick-cooking white rice?

Brown rice has a longer cooking time and a different texture, so it’s not recommended for this recipe as it may result in undercooked grains or overcooked chicken. Stick to quick-cooking rice for best results.

Is it possible to add other vegetables?

Absolutely! You can swap or add to the peas and carrots with options like diced bell peppers, corn, or green beans. Just keep the total vegetable amount around one cup to maintain the proper moisture balance.

What if I don’t have onion soup mix on hand?

You can substitute with a mix of dried onion flakes, onion powder, dried parsley, and a pinch of beef or chicken bouillon powder to mimic that savory flavor profile.

Can I use chicken thighs instead of breasts?

Chicken thighs will work well and tend to stay juicy even more easily, but adjust cooking time slightly if they’re bone-in or thicker pieces. Boneless thighs are the easiest swap.

Why is it called “No-Peek” chicken casserole?

The name comes from covering the dish tightly with foil so you don’t have to open the oven and “peek” during baking. This keeps moisture trapped inside, resulting in tender chicken and creamy rice that’s cooked perfectly.
