Some recipes slip through the cracks of family tradition, and this broccoli chicken apricot casserole is one of those hidden gems that somehow never made it from mom’s kitchen to yours. This sweet and savory combination brings together tender chicken, crisp broccoli, and melted cheese in a surprising apricot sauce that transforms ordinary weeknight cooking into something special. The secret lies in the unexpected marriage of fruit preserves with savory ingredients, creating a dish that’s both comforting and exciting enough to become your new go-to recipe.
Most people skip the apricot preserves completely
The biggest mistake home cooks make with this recipe is thinking the apricot preserves are optional or too weird to work. Many people see fruit preserves in a savory dish and immediately assume it’s going to be too sweet or clash with the other ingredients. This hesitation leads them to either skip the preserves entirely or substitute them with something more “normal” like barbecue sauce, completely missing the point of what makes this casserole special.
The apricot preserves actually balance the richness of the cheese and cream soup, creating a complex sweet-savory profile that elevates the entire dish. Without them, you’re left with just another ordinary chicken and broccoli casserole that tastes like every other recipe floating around Pinterest. The preserves add a glossy finish to the sauce and a subtle fruity note that complements the chicken beautifully, making this casserole recipe stand out from the crowd.
Raw broccoli ruins the whole texture
Nothing kills a good casserole faster than crunchy, undercooked broccoli that squeaks when you bite it. Too many people throw raw broccoli florets straight into the baking dish, thinking the oven time will be enough to cook them through. The result is a casserole with perfectly tender chicken and cheese, but broccoli that’s still tough and bitter, creating an unpleasant contrast that ruins every bite.
The broccoli needs to be blanched or steamed before it goes into the casserole, giving it a head start on cooking and ensuring it becomes tender without turning to mush. Even frozen broccoli needs to be thawed and patted dry to remove excess moisture that can make the casserole watery. This extra step takes maybe five minutes but makes the difference between a casserole that’s restaurant-quality and one that’s just okay.
Dijon mustard gets forgotten in the sauce
Most home cooks focus so much on the apricot preserves that they completely overlook the Dijon mustard, which is actually the secret ingredient that ties everything together. The mustard adds a sharp, tangy bite that cuts through the richness of the mayonnaise and cream soup, preventing the sauce from becoming too heavy or cloying. Without it, the sauce lacks depth and becomes one-dimensional.
Regular yellow mustard won’t work here – it’s too mild and doesn’t have the sophisticated edge that Dijon provides. The mustard also helps emulsify the sauce, creating a smoother texture that coats the chicken and broccoli evenly. Some people try to substitute it with mustard powder, but that misses the acidic component that fresh Dijon brings to balance the sweetness of the preserves.
Dry onion soup mix makes all the difference
The dry onion soup mix often gets treated like an afterthought, but it’s actually doing serious heavy lifting in this recipe. It provides layers of savory depth that you can’t get from just salt and pepper, adding onion, garlic, and other seasonings that have been perfectly balanced by food scientists. Many people try to substitute it with fresh onions or garlic powder, but they miss the concentrated umami punch that the soup mix delivers.
The soup mix also helps thicken the sauce slightly and adds a subtle saltiness that enhances all the other ingredients. Lipton is the gold standard here – their blend has been perfected over decades and consistently delivers the right balance of seasonings. Store brands can work, but they often have different salt levels or missing spices that can throw off the entire dish.
Mayonnaise creates the perfect creamy base
The mayonnaise in this recipe often gets side-eyed by people who think it’s going to make the dish too heavy or gross, but it’s actually the ingredient that creates the luxurious, creamy texture that makes this casserole so addictive. Unlike sour cream or Greek yogurt, mayonnaise doesn’t curdle or separate when heated, maintaining its smooth consistency throughout the baking process.
The mayonnaise also adds richness without the tanginess that sour cream would bring, allowing the apricot and mustard to shine through as the primary sources of acidity. Some people try to lighten it up with Greek yogurt, but that changes the entire character of the dish and can make it watery. The mayonnaise is what gives this casserole its restaurant-quality mouthfeel that keeps people coming back for seconds.
Chicken pieces need to be the right size
Cutting the chicken into proper bite-sized pieces is crucial for this casserole to work correctly. Too many people leave the chicken breasts whole or cut them into massive chunks, which means they don’t cook evenly and create awkward serving situations where people have to cut their food in the casserole dish. The chicken should be cut into pieces that are roughly the same size as the broccoli florets.
Pieces that are about 1-inch square work perfectly – they’re small enough to cook through completely in the 45-minute baking time, but large enough to maintain their texture and not disappear into the sauce. Using a rotisserie chicken is actually a great shortcut here, since it’s already cooked and just needs to be shredded into appropriately sized pieces. This also adds extra seasoning to the dish since rotisserie chickens are typically well-seasoned.
Cheese timing affects the final result
The two-stage cheese addition might seem like unnecessary fussiness, but it’s actually critical for getting the right texture and appearance. Adding all the cheese at once creates a thick, heavy layer that doesn’t melt properly and can become rubbery or separated. The first layer of cheese melts into the sauce, creating creaminess, while the second layer stays on top for that appealing golden-brown finish.
Sharp cheddar works best here because it has enough personality to stand up to the other strong ingredients in the dish. Mild cheddar gets lost, and pre-shredded cheese often contains anti-caking agents that prevent it from melting smoothly. Block cheese that you shred yourself melts much better and creates that perfect stretchy, gooey texture that makes this casserole so satisfying to eat.
Crispy fried onions add essential texture
The crispy fried onions might seem like just a garnish, but they provide a crucial textural contrast that prevents the casserole from being too soft and monotonous. Without them, every bite has the same creamy, tender mouthfeel, which gets boring quickly. The onions add a satisfying crunch and a slightly sweet, caramelized onion taste that complements the apricot preserves beautifully.
French’s French Fried Onions are the classic choice here, but you can also use crushed Ritz crackers or even toasted almonds for different textural elements. The key is adding them at the very end so they don’t get soggy from the steam. Some people skip this step entirely, thinking it’s not important, but it’s actually what separates a good casserole from a great one that people remember and ask for the recipe.
Baking temperature and time matter more than you think
Most people just throw this casserole in whatever oven temperature they’re used to using, but 375°F is specifically chosen to cook the chicken through without drying it out while also allowing the cheese to melt properly and the sauce to bubble and thicken. Going too hot makes the top brown too quickly before the inside is properly heated, while going too low means the cheese never gets that appealing golden color.
The 45-minute baking time is also carefully calculated – it’s long enough for all the ingredients to meld together and for the chicken to reach a safe internal temperature, but not so long that the broccoli becomes mushy or the cheese becomes rubbery. Covering with foil for the first half of baking helps prevent over-browning while ensuring even heating throughout the dish.
This casserole proves that sometimes the best recipes are the ones that never got passed down through traditional family channels. The combination of sweet apricot preserves, tangy Dijon mustard, and rich cheese creates something completely different from typical weeknight dinners. Once you try this version, you’ll understand why it deserves a permanent spot in your recipe rotation, and you might just start your own family tradition of making the casserole that mama never bothered to teach you.

kcalThis sweet and savory casserole combines tender chicken, crisp broccoli, and gooey cheese in an irresistible apricot sauce that will become your new family favorite.
Ingredients
2 lbs boneless, skinless chicken breasts, cut into bite-sized pieces
1 head broccoli, cut into florets
1 (10.5 oz) can cream of chicken soup
1/2 cup mayonnaise
1/2 cup apricot preserves
2 tbsp Dijon mustard
1 (1 oz) package dry onion soup mix
2 cups shredded cheddar cheese, divided
1 cup crispy fried onions (optional)
Directions
- Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish with cooking spray or butter to prevent sticking. This will make cleanup much easier later.
- In a large bowl, whisk together the cream of chicken soup, mayonnaise, apricot preserves, Dijon mustard, and dry onion soup mix until smooth and well combined. The mixture should be creamy with no lumps remaining.
- Spread the broccoli florets evenly across the bottom of the prepared baking dish. If using fresh broccoli, blanch it for 2-3 minutes first, then pat dry. Frozen broccoli should be thawed and patted dry to remove excess moisture.
- Arrange the chicken pieces evenly over the broccoli layer in the baking dish. Season the chicken lightly with salt and pepper if desired. Make sure the chicken pieces are roughly the same size as the broccoli florets for even cooking.
- Pour the apricot sauce mixture evenly over the chicken and broccoli. Use a spoon to spread it around and ensure everything is well coated. The sauce should cover all the chicken and broccoli pieces.
- Sprinkle 1 1/2 cups of the shredded cheddar cheese evenly over the top of the casserole. Reserve the remaining 1/2 cup of cheese for later. The cheese should cover the surface but not be too thick.
- Bake the casserole in the preheated oven for 40-45 minutes, until the chicken is cooked through (internal temperature of 165°F) and the cheese is melted and bubbly. If the top browns too quickly, cover loosely with foil.
- Remove from oven and sprinkle the reserved 1/2 cup of cheddar cheese and crispy fried onions over the top. Return to oven for 5 more minutes until the cheese melts and onions are golden. Let cool for 5 minutes before serving.
Notes
- This casserole can be assembled 24 hours ahead and refrigerated. Let it come to room temperature for 30 minutes before baking, and add an extra 10-15 minutes to the cooking time if needed.
- Leftover rotisserie chicken works great in this recipe – just shred it into bite-sized pieces and skip the cooking time concerns.
- For extra crunch, try substituting crushed Ritz crackers or toasted sliced almonds for the crispy fried onions.
- This casserole freezes well for up to 3 months. Thaw overnight in the refrigerator before reheating.
Frequently Asked Questions
Q: Can I substitute the apricot preserves with something else?
A: While you could use peach preserves or orange marmalade, the apricot preserves provide a unique sweet-tart balance that really makes this dish special. Avoid substituting with barbecue sauce or other condiments as they’ll completely change the character of the casserole.
Q: What if I don’t like mayonnaise?
A: You can substitute the mayonnaise with an equal amount of sour cream or plain Greek yogurt, but the texture will be slightly different. The mayonnaise creates a smoother, richer sauce that doesn’t separate during baking like dairy products sometimes can.
Q: Can I use frozen broccoli instead of fresh?
A: Yes, frozen broccoli works perfectly fine. Just make sure to thaw it completely and pat it dry with paper towels to remove excess moisture before adding it to the casserole. Skip the blanching step if using frozen since it’s already been partially cooked.
Q: How do I know when the chicken is fully cooked?
A: The chicken should reach an internal temperature of 165°F when checked with a meat thermometer. The pieces should also look opaque throughout with no pink areas, and the juices should run clear when pierced with a fork.
