How to Make Easy Harvest chicken casserole recipe
Step 1: Preheat Your Oven
Start by preheating your oven to 375°F (190°C). This ensures your casserole bakes evenly and thoroughly.
Step 2: Prepare the Veggies
In a large baking dish (9×13 works perfectly), combine the sweet potatoes, Brussels sprouts, garlic, onion, smoked paprika, and cumin. Drizzle with half of the avocado oil, then season with salt and pepper. Toss everything well to make sure each piece gets coated—this will help all those flavors meld beautifully. Pour over the low-sodium chicken broth and cover the dish tightly with aluminum foil.
Step 3: Bake Until Tender
Place your vegetable medley in the preheated oven. Bake until they’re fork-tender—this usually takes about 22 to 25 minutes. The aroma wafting through your kitchen will be simply irresistible!
Step 4: Sear the Chicken
While your veggies are roasting away, heat up the remaining tablespoon of avocado oil in a large skillet over medium-high heat. Add those delightful chunks of chicken breast seasoned with salt and pepper. Sear them until they turn golden brown on all sides—about 3 to 4 minutes should do it. This step adds depth of flavor to your casserole!
Step 5: Combine & Bake Again
Once your veggies are done baking, stir in the seared chicken pieces along with those lovely dried cranberries. Sprinkle shredded cheddar cheese over everything before returning it to the oven uncovered. Bake again for another 10 to 12 minutes until the chicken is cooked through and that gooey cheese melts beautifully on top.
Step 6: Serve & Enjoy!
Take your casserole out of the oven—it should look golden brown and inviting! Garnish with sliced green onions, pumpkin seeds, and chopped parsley for that fresh touch. Slice yourself a generous portion while it’s hot, gather your loved ones around, and savor every delicious bite together!
Pro Tips for Making Easy Harvest chicken casserole recipe
Making this casserole is a breeze, but a few tips can elevate your dish to perfection!
Use Fresh Ingredients: Fresh vegetables not only enhance the flavor but also add vibrant colors and nutrients to your casserole, making it more appealing and healthy.

Let It Rest: Allowing the casserole to sit for a few minutes after removing it from the oven helps the flavors meld together and makes serving easier.
