• Low-effort, dump-and-bake recipe perfect for busy weeknight meal prep

Ingredients Needed

For the Rice Base

• 2 cups instant brown or white rice (Minute rice)
• 1 can (10.5 oz) healthy-request or low-sodium cream of mushroom soup
• 1 can (10.5 oz) healthy-request or low-sodium cream of chicken soup
• 1 cup water (or low-sodium chicken bone broth for extra protein)
• 1 tbsp light butter or olive oil (for greasing the pan)

For the Protein Top

• 1.5 lbs boneless, skinless chicken breasts (about 4 medium breasts)
• 1 packet dry onion soup mix (e.g., Lipton)

How to Make Our High-Protein Forgotten Chicken Casserole

1. Preheat your oven to 350°F (175°C). Use 1 tablespoon of butter or oil to generously grease the bottom and sides of a 9×13-inch baking dish.
2. Mix the rice base by combining the cream of mushroom soup, cream of chicken soup, water (or bone broth), and instant rice in a bowl. Stir until well combined.
3. Assemble the casserole by pouring the creamy rice mixture into the bottom of your prepared baking dish and spreading it out into an even layer.
4. Add the chicken by arranging the boneless, skinless chicken breasts directly on top of the wet rice bed.
5. Season evenly by sprinkling the dry onion soup mix over the top of each chicken breast.
6. Cover and seal the baking pan tightly with aluminum foil. Crimp the edges tightly around the rim to trap the steam—this keeps the chicken moist and ensures the rice cooks properly!
7. Bake for 60 to 75 minutes until the chicken reaches an internal temperature of 165°F and the rice is completely tender.
8. Rest and serve for 5 minutes before serving hot.

Storage & Serving Suggestions

• Refrigeration: Store cooled leftovers in an airtight container in the fridge for up to 4 days.
• Meal Prep Reheating: Microwave individual portions with a splash of water or broth for 1.5–2 minutes to keep the rice fluffy and moist.
• Pairing Ideas: Serve alongside steamed green beans, roasted broccoli, or a light crisp side salad to complete your volume-dense, high-protein meal.

Tips & FAQs

Can I use regular long-grain white rice instead of instant rice?

Instant (Minute) rice is crucial for this recipe. Standard long-grain raw rice requires significantly more liquid and longer cooking times, which can lead to dry chicken or undercooked rice.

How can I boost the protein content even further?

Swap the 1 can of water for 1 cup of rich chicken bone broth to instantly add 9–10 grams of extra protein to the overall dish without extra fat or calories.

Why is sealing the foil so important for this recipe?

Trapping the steam inside the baking dish is the secret to getting soft, creamy rice and tender, juicy chicken breasts simultaneously. Make sure your foil wrap is extra tight around all four corners!
