Campbell’s Supper Bakes Copycat Recipe: Homemade Casserole Magic

This homemade casserole captures the nostalgic comfort of the classic Supper Bakes we all remember. I developed this recipe to recreate that same satisfying combination of creamy filling and crispy topping without the canned convenience.

The secret lies in layering simple ingredients with a homemade sauce that’s richer than the original. A buttery breadcrumb topping baked to golden perfection completes the dish with that signature crunch.

What you get is a hearty, family-friendly meal that delivers all the flavor of the store-bought version with the pride of making it yourself. The creamy filling bakes up bubbly and thick, while the topping adds the perfect textural contrast.

Serve this straight from the oven for a meal that’s sure to become a new family favorite. The recipe scales easily for feeding a crowd or meal prepping for the week.

Ingredients for Campbell’s Supper Bakes Copycat

Pantry staples plus a few fresh picks. Probably have most of this already.

The chicken is the base here. Boneless, skinless breasts work best—thighs get too greasy. I grab mine from Costco for bulk savings, but any supermarket will do. The cream of chicken soup is non-negotiable for that classic Supper Bakes flavor—Campbell’s if you want to stay true to the original (or use a high-quality generic). Freshly grated cheddar melts better than pre-shredded, so spring for a block if you can.

No cream of chicken? Cream of mushroom works in a pinch (just add a little poultry seasoning). Fresh out of sour cream? Greek yogurt at the same amount gets you close. The veggies can be any frozen mix—whatever you’ve got in the freezer. For the breadcrumbs, seasoned or plain both work, but I like adding a pinch of garlic powder to plain ones for extra flavor.

Assemble and bake right away, or prep it the night before—just add 10 minutes to the baking time if it’s cold. Leftovers keep 3-4 days in the fridge, reheats beautifully. Freeze before baking for up to 2 months (thaw overnight before cooking).

Step-by-Step Instructions for Campbell’s Supper Bakes Copycat

Here’s how to recreate that nostalgic casserole magic right in your own kitchen.

Step 1: Prepare the Chicken and Sauce Base

Start by preheating your oven to 375°F. Dice the 1.5 lb chicken breast into bite-sized pieces and season with 1 tsp salt and 0.5 tsp black pepper. In a large skillet, sauté the diced onion and minced 2 cloves garlic cloves in 0.5 cup butter until soft and fragrant.

Stir in the 0.25 cup all-purpose flour to create a roux, cooking for 1-2 minutes until it turns a light golden color. This thickens the sauce base beautifully. Slowly whisk in the 1 cup chicken broth and 0.5 cup milk, ensuring no lumps form.

Add the 2 cans cream of chicken soup and 1 cup sour cream, stirring until smooth. The mixture should coat the back of a spoon with a velvety texture.

Step 2: Combine All Ingredients for the Casserole

In a large mixing bowl, combine the cooked chicken, prepared sauce, 2 cups frozen mixed vegetables, and 1.5 cups cheddar cheese (reserving 0.5 cup for the topping). The vegetables will soften during baking, so no need to thaw them first.

I like to let this mixture sit for 5 minutes to allow the flavors to meld. The sauce should look creamy with visible pieces of chicken and vegetables throughout. If it seems too thick, add a splash more broth to reach your desired consistency.

Step 3: Assemble and Top the Casserole

Transfer the chicken and sauce mixture to a greased 9×13-inch baking dish, spreading it evenly with a spatula. The dish should be about three-quarters full. This size ensures even cooking and a perfect crust-to-filling ratio.

In a small bowl, mix the remaining 0.5 cup cheddar cheese with the 2 cups bread crumbs. Sprinkle this mixture evenly over the top of the casserole, pressing down gently to help it adhere. The bread crumbs will turn golden brown during baking, creating that signature crispy topping.

Step 4: Bake to Golden Perfection

Bake uncovered in the preheated oven for 30-35 minutes, or until the casserole is bubbling around the edges and the topping is deep golden brown. You’ll know it’s done when a knife inserted in the center comes out hot to the touch.

Let the casserole rest for 10 minutes before serving. This allows the sauce to thicken slightly and makes it easier to portion. The top should have a crispy, golden crust while the inside remains creamy and comforting.

Best Sauces and Condiments for This campbells supper bakes copycat

Creamy Enhancements

I love drizzling 2 tbsp ranch dressing over each serving—the tangy coolness cuts through the richness beautifully. It pairs especially well with the creamy chicken and cheese filling, adding a refreshing contrast without overpowering the dish.

Spicy Kick

For heat lovers, add 1 tbsp hot sauce like Frank’s RedHot to the sauce mixture before baking. The vinegar-based tang complements the creamy base, and the spice level is just right for most palates. I sometimes keep a bottle on the table for customizing.

You can also sprinkle ½ tsp crushed red pepper flakes over the breadcrumb topping before baking for a subtle, consistent heat. 🌶️

Herb Infusions

Fresh herbs elevate this dish instantly. Stir 2 tbsp chopped parsley into the sauce for a bright, fresh note. Alternatively, mix 1 tsp dried thyme into the breadcrumb topping for an earthy aroma that fills your kitchen as it bakes.

Cheesy Toppings

Just before serving, sprinkle ¼ cup grated Parmesan over the top for an extra umami punch. The salty, sharp flavor contrasts perfectly with the creamy filling. For a fun twist, use Parmesan crisps crushed over individual servings.
