Ingredient Notes
What kind of egg noodles? Wide egg noodles are traditional and hold up well to baking. Extra-wide noodles work too. You can also use any short pasta (rotini, shells, elbows) — just cook them according to package directions before adding to the casserole.
What kind of chicken? Rotisserie chicken is the ultimate shortcut. You can also use leftover roasted chicken, poached chicken breasts, or even canned chicken (drained). Shred or dice into bite-sized pieces.
What kind of corn? Canned corn (drained) or frozen corn both work. If using frozen, no need to thaw first. Fresh corn cut off the cob is also delicious when in season.
What kind of cheese? Sharp cheddar provides the most flavor. Colby Jack is milder and melts beautifully. Mozzarella adds stretchiness. Use whatever you have — or a combination.
What are French fried onions? Those crispy, salty, crunchy onions in a can (French’s is the classic brand). They add an incredible crunchy topping. If you don’t have them, substitute crushed Ritz crackers mixed with melted butter, or panko breadcrumbs.
Can I use a different cream soup? Yes. Cream of mushroom or cream of celery both work beautifully. Each will change the flavor slightly — cream of mushroom adds earthy depth, cream of celery adds herbal notes.
Step-by-Step Instructions
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) .
Lightly grease a 9×13-inch baking dish with nonstick spray or butter.
Step 2: Cook the Egg Noodles
Bring a large pot of salted water to a boil. Add 2 cups of egg noodles and cook according to package directions until al dente (firm to the bite).
Drain the noodles and set aside.
Pro tip: Cook the noodles about 1 minute less than the package recommends — they’ll finish cooking in the oven and won’t become mushy.
Step 3: Sauté the Onion (Optional but Recommended)
In a small skillet over medium heat, sauté the diced onion in a little butter or oil until softened, about 3–4 minutes. This step adds depth of flavor, but you can skip it if you’re short on time (add the onion raw to the casserole — it will soften during baking).
Step 4: Combine the Casserole Ingredients
In a very large bowl, combine:
-
Cooked egg noodles
-
Sautéed (or raw) onion
-
2 cups cooked chicken (shredded or diced)
-
1 tablespoon garlic powder
-
2 cups corn (drained if canned)
-
½ cup shredded cheese
-
1 cup milk
-
½ cup crumbled bacon
-
2 cans cream of chicken soup
Stir until everything is well combined and the creamy sauce coats all the ingredients.
Step 5: Transfer to Baking Dish
Pour the mixture into the prepared 9×13-inch baking dish and spread it into an even layer.
Step 6: Add the Toppings
Sprinkle the remaining ½ cup of cheese (if you reserved any — or use extra) and ¾ cup of French fried onions evenly over the top of the casserole.
Step 7: Bake
Bake at 350°F for 25 to 30 minutes, until the casserole is hot and bubbly and the topping is golden brown and crispy.
If the topping is browning too quickly, loosely tent a piece of foil over the casserole for the last 10 minutes.
Step 8: Rest and Serve
Let the casserole rest for 5–10 minutes before serving. This allows the sauce to set slightly and makes it easier to scoop clean portions.
Serve hot, garnished with fresh parsley or extra bacon bits if desired.
Variations & Tips
Add Vegetables
Stir into the casserole before baking:
-
1 cup frozen peas – Adds sweetness and color
-
1 cup chopped broccoli – Steam first or use frozen
-
1 cup diced bell peppers – Adds crunch and color
-
1 cup sliced mushrooms – Sauté first to remove moisture
Make It with Turkey
Substitute 2 cups of cooked, shredded turkeyfor the chicken. This is a great way to use up Thanksgiving leftovers!
Make It with Ham
Substitute 2 cups of diced ham for the chicken. Ham adds a salty, smoky flavor that pairs beautifully with the cheese and corn.
Make It Spicy
-
Add ½ teaspoon of cayenne pepper to the mixture
-
Add 1 teaspoon of red pepper flakes
-
Use pepper jack cheese instead of cheddar
-
Add 1 teaspoon of hot sauce to the creamy mixture
Make It Without Canned Soup
Make your own creamy base:
-
2 tablespoons butter
-
2 tablespoons flour
-
1½ cups chicken broth
-
½ cup milk
-
Salt, pepper, garlic powder to taste
Melt butter, whisk in flour, slowly add broth and milk, and cook until thickened. Use in place of the cream of chicken soup and milk.
Make It Gluten-Free
-
Use gluten-free egg noodles or gluten-free pasta
-
Use gluten-free cream of chicken soup(several brands make it)
-
Use gluten-free French fried onions (or substitute crushed gluten-free crackers)
Make It Dairy-Free
-
Use dairy-free milk (oat, almond, or cashew)
-
Use dairy-free cream of chicken soup (or make your own with dairy-free milk and broth)
-
Use dairy-free shredded cheese (Daiya, Violife, or Follow Your Heart)
-
Omit the cheese or use nutritional yeast for a cheesy flavor
Storage & Reheating
Refrigerator: Store leftovers in an airtight container for up to 4 days. The French fried onions will soften as they sit — that’s normal.
Reheating:
-
Microwave: 1–2 minutes per serving.
-
Oven (best for re-crisping topping): 350°F for 10–15 minutes, covered with foil for the first 10 minutes, then uncovered for the last 5.
-
Toaster oven: 350°F for 8–10 minutes.
Freezing: This casserole freezes beautifully for up to 2 months. Assemble the casserole completely (but don’t bake), cover tightly with foil, and freeze. When ready to bake, thaw overnight in the refrigerator, then bake as directed (add 10–15 minutes to the baking time). You can also freeze baked leftovers — the topping will be softer, but the flavor remains excellent.
Frequently Asked Questions (FAQs)
Do I have to cook the egg noodles before adding them to the casserole?
Yes. Unlike some casseroles that use uncooked pasta (which cooks in the sauce), this recipe works best with pre-cooked noodles. Cooking them first ensures they have the right texture and don’t absorb too much of the sauce.
Can I use leftover rotisserie chicken?
Absolutely. Rotisserie chicken is the perfect shortcut. You’ll need about 2 cups of shredded meat — that’s roughly half a rotisserie chicken.
Can I use frozen corn instead of canned?
Yes. Use 2 cups of frozen corn kernels. No need to thaw them first. If using fresh corn, cut it off the cob (about 3–4 ears).
My casserole is too dry. What went wrong?
A few possibilities:
-
You used too many noodles or not enough sauce
-
You overbaked it (check at 25 minutes)
-
You used low-fat or skim milk (whole milk or 2% works best)
-
You didn’t add enough milk or soup
To fix: add a splash of milk or broth before reheating.
My casserole is too soupy. What went wrong?
A few possibilities:
-
You didn’t drain the corn (if using canned)
-
You added too much milk
-
You underbaked it (the sauce thickens as it cools)
To fix: let it rest longer before serving, or return to the oven for another 10 minutes.
Can I make this ahead of time?
Yes. Assemble the casserole completely (including the topping), cover, and refrigerate for up to 24 hours. When ready to bake, add 10–15 minutes to the baking time. If the topping seems soggy, you can add a fresh layer of French fried onions before baking.
What can I use instead of French fried onions?
-
Crushed Ritz crackers mixed with 2 tablespoons melted butter
-
Panko breadcrumbs tossed with melted butter
-
Crushed cornflakes mixed with melted butter
-
Additional shredded cheese (for a cheesy top)
-
Crushed potato chips (for a salty crunch)
