Ingredient Notes
What is kielbasa? Kielbasa is a Polish smoked sausage, typically made from pork. It’s fully cooked, so you’re just heating it through and browning the edges. It has a rich, garlicky, smoky flavor that stands up beautifully to the creamy sauce. You can also use andouille sausage for a spicier kick or turkey kielbasa for a lighter option.
What kind of egg noodles? Wide egg noodles are traditional and hold up well to baking. Extra-wide noodles work too. Avoid very thin noodles (like fine egg noodles) — they can become mushy. If you don’t have egg noodles, any short pasta (rotini, shells, elbows) works, but the texture will be different.
Why low-sodium broth? The kielbasa and cream of mushroom soup both contain plenty of salt. Low-sodium broth lets you control the salt level. If you only have regular broth, reduce or omit any additional salt.
Can I use a different cream soup? Yes. Cream of chicken or cream of celery both work beautifully. Cream of mushroom adds the most savory, earthy depth. Cream of chicken is milder and richer.
Step-by-Step Instructions
Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C) . Lightly grease a 9×13-inch glass baking dish with nonstick spray or a thin layer of oil so the noodles don’t stick.
Step 2: Add the Uncooked Noodles
Spread the 12 ounces of uncooked wide egg noodlesevenly in the bottom of the prepared baking dish, making sure they’re in a mostly even layer so they cook at the same rate.
Why no boiling? The noodles cook directly in the sauce, absorbing the creamy liquid as they bake. This saves time, uses fewer dishes, and results in noodles that are infused with flavor.
Step 3: Make the Sauce
In a medium bowl or large measuring cup, whisk together:
-
3 cups low-sodium chicken broth
-
1 can (10.5 ounces) condensed cream of mushroom soup
Whisk until smooth and well combined. This will be your baking liquid and sauce.
Step 4: Pour the Sauce Over the Noodles
Pour the broth and soup mixture evenly over the dry egg noodles. Gently press down any noodles that are sticking up so they’re mostly submerged in the liquid. It’s okay if a few edges are peeking out — they’ll soften as the casserole bakes.
Step 5: Add the Kielbasa
Arrange the sliced kielbasa in a single, even layer over the top of the noodles. The slices can overlap slightly, but try not to pile them too high in one spot so they brown nicely.
Step 6: Cover and Bake
Cover the baking dish tightly with foil, crimping the edges to trap the steam inside. Place the dish on the middle rack of the preheated oven.
Bake, covered, for 30 minutes.
Step 7: Stir and Finish Uncovered
Carefully remove the foil — watch for the hot steam. Gently stir the noodles, pulling some of the kielbasa down into the sauce and bringing some noodles up to the top so everything cooks evenly.
Return the dish to the oven, uncovered, and bake for an additional 15 to 20 minutes, or until:
-
The noodles are fork tender
-
Most of the liquid has been absorbedinto a creamy sauce
-
The kielbasa on top is lightly browned around the edges
Step 8: Optional Extra Browning
If you’d like a bit more browning on the kielbasa, move the dish to the top rack for the last 3 to 5 minutesof baking, watching closely so it doesn’t overbrown.
Step 9: Rest and Serve
Remove the baking dish from the oven and let the casserole rest for about 5 to 10 minutes before serving. This helps the sauce thicken slightly and makes it easier to scoop perfectly tender noodles and browned kielbasa onto each plate.
Variations & Tips
Add Vegetables
Stir into the casserole before baking:
-
1 cup frozen peas and carrots – Classic addition
-
1 cup frozen peas – Sweet and simple
-
1 cup sliced mushrooms – Fresh or canned
-
1 cup chopped broccoli – Adds color and crunch
-
1 cup frozen corn – Sweet and colorful
Add Cheese
Sprinkle 1 cup of shredded cheddar, Swiss, or Parmesan cheese over the top during the last 5–10 minutes of baking (uncovered). The cheese will melt into a golden, bubbly topping.
Add a Crumb Topping
Mix ½ cup of panko breadcrumbs with 2 tablespoons of melted butterand sprinkle over the casserole before the final uncovered bake. This adds a crispy, crunchy topping.
Make It Spicy
-
Use spicy andouille sausageinstead of kielbasa
-
Add ½ teaspoon of red pepper flakes to the sauce
-
Add 1 teaspoon of hot sauce(like Tabasco or Frank’s RedHot)
-
Use spicy cream of mushroom soup(if available)
Make It with Canned Soup Only (No Broth)
If you don’t have chicken broth, you can use 2 cans of cream of mushroom soup and 2 cups of water instead of the broth. The flavor will be slightly less complex but still delicious.
Make It Gluten-Free
-
Use gluten-free wide egg noodles(several brands make them)
-
Use gluten-free cream of mushroom soup (several brands make it)
-
Check that your kielbasa is gluten-free (most are, but check the label)
Make It in a Slow Cooker
-
Add uncooked noodles to the greased slow cooker.
-
Whisk together broth and soup. Pour over noodles.
-
Top with sliced kielbasa.
-
Cook on LOW for 3–4 hoursor HIGH for 1½–2 hours.
-
Stir before serving. (Note: The slow cooker version won’t have the baked, browned top.)
Storage & Reheating
Refrigerator: Store leftovers in an airtight container for up to 4 days. The sauce will thicken as it cools — that’s normal.
Reheating:
-
Microwave: 1–2 minutes per serving. Add a splash of milk or broth if it seems dry.
-
Oven: 350°F for 10–15 minutes, covered with foil to prevent drying out.
-
Skillet: Warm over medium-low heat, adding a splash of broth or milk to loosen.
Freezing: This casserole freezes reasonably well for up to 2 months. The creamy sauce may separate slightly upon thawing, but stirring usually brings it back together. Thaw overnight in the refrigerator before reheating.
Frequently Asked Questions (FAQs)
Do I need to cook the noodles before adding them to the casserole?
No. That’s the beauty of this recipe. The noodles cook directly in the sauce, absorbing all the creamy flavor as they bake. This saves time and dishes.
Can I use a different pasta shape?
Yes. Short pasta shapes like rotini, shells, or elbows work well. Avoid long noodles like spaghetti — they won’t distribute evenly. If using a different shape, the cooking time may vary slightly.
Why are my noodles still hard after baking?
A few possibilities:
-
You didn’t add enough liquid (the noodles need to be mostly submerged)
-
Your oven temperature is too low (use an oven thermometer to check)
-
You didn’t cover the dish tightly enough (steam escaped)
-
You used a different type of pasta that needs more liquid or time
Can I use water instead of chicken broth?
Yes, but the casserole will be less flavorful. If using water, add 1 teaspoon of chicken bouillon granules or a pinch of salt, garlic powder, and onion powder to boost the flavor.
Can I add more kielbasa?
Absolutely. Use up to 1½ pounds of kielbasa if you want a meatier casserole. No other adjustments needed.
What should I serve with this casserole?
This is a complete meal on its own, but it pairs beautifully with:
-
A simple green salad – With a tangy vinaigrette
-
Steamed green beans or broccoli – Adds color and crunch
-
Roasted asparagus – Elegant and easy
-
Crusty bread – For sopping up extra sauce
Can I make this dairy-free?
Yes. Use a dairy-free cream of mushroom soup (several brands make it) and ensure your kielbasa is dairy-free (most are). The noodles are naturally dairy-free.
What to Serve With It

-
This casserole has protein (kielbasa), carbohydrates (noodles), and a creamy sauce. It’s a complete meal on its own.

Why This Recipe Works
This four-ingredient casserole is greater than the sum of its parts. Here’s why each ingredient is essential:
Wide egg noodles provide the perfect canvas — their shape holds onto the creamy sauce, and they cook evenly in the liquid.
Smoked kielbasa brings rich, garlicky, smoky flavor that infuses the entire dish as it bakes.
Cream of mushroom soupcreates a savory, earthy base that makes the sauce taste complex and homemade.
Chicken broth thins the soup to the perfect consistency and adds depth, while also providing the liquid the noodles need to cook.
The covered bake steams the noodles until tender. The uncovered bake allows the sauce to thicken and the kielbasa to brown. It’s simple, foolproof, and delicious.
