This cashew chicken quinoa bake transforms ordinary ingredients into a protein-packed, Asian-inspired casserole that truly satisfies. The combination of tender chicken, nutty quinoa, and crunchy cashews creates a balanced one-dish meal that requires minimal effort but delivers maximum flavor.
The first time I made this dish was during a particularly busy week of meal prepping. I was immediately sold on how the ingredients merged together creating this incredible flavor profile while still keeping the dish wholesome and satisfying. Now it's in our regular dinner rotation.
Ingredients
- Quinoa creates the nutty foundation for this dish and absorbs all the delicious flavors while providing complete protein
- Yellow onion adds aromatic sweetness when cooked that balances the savory elements
- Bell peppers provide bright color vibrant flavor and a slight crunch to contrast the softer textures
- Chicken breast delivers lean protein that remains tender when baked with the sauce
- Hoisin sauce brings that signature sweet and savory Asian flavor profile that makes this dish irresistible
- Fresh garlic and ginger form the aromatic base that gives authentic depth to the sauce
- Soy sauce enhances the umami factor while seasoning the entire dish perfectly
- Water ensures the quinoa cooks properly while helping distribute the flavors throughout
- Cashews offer a buttery crunch that elevates the texture contrast look for plump unsalted varieties
Step-by-Step Instructions
- Prepare the baking dish
- Preheat your oven to 375°F and thoroughly coat a 9x13 casserole dish with cooking spray ensuring all corners are covered. This prevents sticking and makes cleanup much easier.
- Layer the base ingredients
- Spread the rinsed uncooked quinoa evenly across the bottom of your prepared dish. This even distribution ensures proper cooking. Next layer the diced onions and chopped bell peppers on top followed by the bite sized chicken pieces arranged in a single layer.
- Create the flavorful sauce
- In a separate bowl combine the hoisin sauce minced garlic soy sauce fresh ginger and 1.25 cups of water whisking until completely smooth. The consistency should be somewhat thin as the quinoa will absorb much of the liquid during baking.
- Assemble and begin baking
- Pour the sauce evenly over the entire dish making sure to cover all the chicken and reach the corners. Cover tightly with foil to trap steam which helps cook the quinoa properly. Bake at 375°F for 45 minutes which allows the quinoa to absorb the liquid and the chicken to cook through.
- Add cashews and finish
- Remove the dish from the oven but keep it on. Uncover and sprinkle the cashews evenly across the top. Return to the oven uncovered for another 10 minutes which lightly toasts the cashews while allowing any excess liquid to evaporate.
- Rest and serve
- Allow the casserole to rest for 5 to 10 minutes after removing from the oven. This resting period allows the flavors to settle and any remaining liquid to be absorbed. Garnish with sliced green onions and sesame seeds just before serving for a fresh finish.

Hoisin sauce is truly the secret ingredient in this recipe. The first time I brought this to a potluck dinner my friend's husband who typically avoids chicken dishes went back for seconds. He later told me it was the perfect balance of sweet and savory that won him over. Now whenever we have gatherings I'm specifically requested to bring this dish.
Meal Prep Magic
This cashew chicken quinoa bake actually improves with time making it ideal for meal preparation. After cooling completely portion it into individual containers and refrigerate for up to four days. The flavors continue to develop overnight as the quinoa absorbs more of the sauce. For reheating simply microwave until warmed through around 2 minutes or heat in the oven at 350°F for about 15 minutes if you prefer a crisper top.
Smart Substitutions
This recipe welcomes adaptations based on what you have available. Brown rice can replace quinoa though you may need to increase liquid by ¼ cup and cooking time by 10 minutes. For a vegetarian version substitute the chicken with firm tofu or chickpeas. Peanuts or almonds can stand in for cashews if needed. For those watching sodium intake look for low sodium versions of both hoisin and soy sauce or try coconut aminos as a soy sauce alternative.
Serving Suggestions
While this dish stands perfectly on its own adding a simple side elevates it further. A crisp cucumber salad with rice vinegar provides refreshing contrast to the hearty bake. For additional vegetables steam some broccoli or bok choy to serve alongside. If serving to guests consider presenting it family style in the baking dish garnished with plenty of green onions sesame seeds and additional cashews for visual appeal and textural contrast.

Pro Tips
For extra flavor lightly toast the quinoa in a dry pan before adding to the baking dish which enhances its nutty characteristics
If using frozen chicken allow it to fully thaw and pat dry before dicing to prevent excess moisture in the finished dish
The cashews can be added from the beginning for softer texture or in the last 10 minutes as directed for maximum crunch
Frequently Asked Questions About Recipes
