Ingredients for baked mac and cheese with sausage
Six ingredients make this creamy, crispy mac and cheese with sausage the ultimate comfort dish.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 1 ½ lbs | Uncooked, medium or elbow shape |
| Kielbasa Sausage 🌭 | 1 lb | Smoked or fresh, sliced into rounds |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded, block preferred |
| Monterey Jack Cheese 🧀 | 1 cup | Shredded, mild flavor balance |
| Heavy Cream 🥛 | 1 cup | Full-fat for creaminess |
| Whole Milk 🥛 | 1 cup | Warmed for smooth sauce |
| Butter 🧈 | ½ cup | Unsalted, melted |
| All-Purpose Flour 🌾 | ¼ cup | For roux thickening |
| Mustard Powder 🌶️ | 1 tsp | Adds tangy depth |
| Garlic Powder 🧄 | 1 tsp | Or 2 fresh cloves minced |
| Onion Powder 🧅 | 1 tsp | For savory base |
| Salt 🧂 | 1 ½ tsp | Adjust to taste |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Panko Breadcrumbs 🍞 | ½ cup | For crispy topping |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For breadcrumb crispiness |
The cheeses are where the magic happens. Sharp cheddar gives that classic tang, while Monterey Jack keeps it smooth—together they create the perfect balance. Grab a block and shred it yourself (pre-shredded gets clumpy). For the sausage, Kielbasa is ideal—it holds up during baking and adds smoky flavor. If you can't find it, Italian sausage works too, but remove the casing first. I always double-check the fat content—20% or higher makes the sauce richer. For the pasta, elbow macaroni is traditional, but penne or cavatappi (the fancy twisted kind) add fun texture.
No sharp cheddar? Pepper jack or Colby Jack work in a pinch, though the flavor will be milder. Running low on heavy cream? Half-and-half or whole milk will stretch it further, but the sauce won't be as velvety. Fresh garlic is worth it here—2 cloves minced adds way more flavor than powder. For the breadcrumbs, panko is non-negotiable—it stays crispy while regular breadcrumbs turn soggy. Pro tip: Toast the breadcrumbs in the oven for 5 minutes before adding them—crispier topping guaranteed. The mustard powder might seem small, but it's what keeps the sauce from getting too heavy.
This reheats like a dream—just cover with foil and pop in the oven at 350°F for 15-20 minutes. Keeps for 4-5 days in the fridge, but honestly, it disappears faster than that. For meal prep, assemble the dish, then refrigerate unbaked—bake straight from the fridge for 10-15 extra minutes. The cheese sauce freezes beautifully too—just thaw overnight in the fridge before reheating. Leftovers? Toss in a skillet with a splash of milk to loosen, then crisp up under the broiler for 2 minutes—crispy again in no time.
Why You'll Love This Recipe
- One-Pan Magic: I swear by this recipe because it’s all about minimal cleanup—just one sheet pan, a handful of elbow macs, and that smoky kielbasa slicing itself into bite-sized pieces while you mix the cheese sauce. No boiling pasta in separate pots here.
- Cheese Overload (In the best way): Sharp cheddar and Monterey Jack melt into this creamy, stretchy blanket, while the sausage adds just enough savory bite to cut through the richness. Honestly, the first bite makes me forget I’m even cooking.
- Game for Any Gathering: This feeds a crowd without breaking the bank—double the recipe for potlucks, halve it for a lazy Sunday, or pack it for lunchboxes (yes, really). The sausage keeps it hearty enough for dinner but simple enough for a weekday fix.
- Leftovers That Don’t Suck: Between us, most baked mac and cheese turns into a sad, dry mess the next day. Not this one. The heavy cream keeps it luscious, and the crispy top? Still chef’s kiss reheated. I’ve eaten this cold straight from the fridge—no judgment.
Step-by-step instructions for baked mac and cheese with sausage
Here's how to create that perfect creamy center with crispy golden breadcrumbs and smoky sausage goodness.
Cook the Elbow Macaroni Al Dente
Bring a large pot of water to a rolling boil and add 1.5 lbs elbow macaroni. Season generously with salt—it should taste like the ocean. Cook until just al dente, about 1 minute less than package instructions. You want pasta that's tender but still has a slight bite.
Drain the pasta in a colander and immediately rinse under cold water for 10 seconds to stop the cooking process. Shake off any excess water and return the pasta to the pot. This quick rinse prevents the pasta from becoming mushy when mixed with the cheese sauce later. Add 1 tablespoon extra-virgin olive oil and toss to coat—this helps prevent sticking and adds a subtle richness.
Brown the Kielbasa and Make the Creamy Sauce
While the pasta cooks, heat a large skillet over medium heat and add the 1 lb kielbasa sausage sliced into rounds. Cook for 5-6 minutes, turning occasionally, until the sausage is golden brown and slightly crispy on the edges. Remove from heat and set aside, leaving the rendered fat in the pan.
In the same skillet, reduce heat to medium-low and add 0.5 cup butter and 0.25 cup all-purpose flour. Whisk constantly for 2-3 minutes until the mixture forms a smooth, pale roux and smells nutty. This is your sauce foundation—don't walk away as it can burn quickly.
Combine Cheese and Seasonings for Ultimate Creaminess
Pour in 1 cup heavy cream and 1 cup whole milk (warm them slightly first by placing the milk in a microwave-safe bowl for 20 seconds) while whisking vigorously. Bring to a gentle simmer and cook for 3-4 minutes until slightly thickened. Remove from heat and stir in 2 cups sharp cheddar cheese, 1 cup monterey jack cheese, 1.5 tsp salt, 0.5 tsp black pepper, 1 tsp garlic powder, 1 tsp onion powder, and 1 tsp mustard powder.
Stir constantly until the cheese melts completely and the sauce becomes smooth and velvety. If the sauce looks too thick, add 1-2 tablespoons of pasta water to reach your desired consistency. This is where all the magic happens—the tangy mustard powder and smoky sausage flavors meld perfectly with the rich cheeses.
Assemble and Bake for the Perfect Crispy Top
Preheat your oven to 375°F. In a large greased baking dish (about 9x13 inches), combine the cooked pasta, sausage, and cheese sauce. Mix thoroughly until every noodle is coated in that creamy goodness. The mixture should be thick but still pourable.
In a small bowl, combine 0.5 cup panko breadcrumbs with 1 tablespoon extra-virgin olive oil. Sprinkle this mixture evenly over the top of the mac and cheese, pressing down gently with a spatula to ensure even coverage. This crispy topping is what makes this dish truly special—don't skip it!
Bake to Golden Perfection
Bake uncovered for 20-25 minutes until the top is golden brown and bubbly, and the edges are slightly crispy. The cheese sauce should be heated through but still creamy—not dry or stringy. For the last 2 minutes, you can broil on high to get extra crispiness on top, but watch closely to avoid burning.
Let the mac and cheese rest for 5 minutes before serving. This resting time allows the layers to set slightly, making it easier to slice and serve. The result should be a creamy, cheesy center with a crispy, golden top and perfectly cooked sausage throughout. Serve immediately while hot and enjoy every gooey, delicious bite!
Pro Tips For Making Baked Mac And Cheese With Sausage
- CRISPY SAUSAGE FIRST: Slice the kielbasa into ½-inch rounds before baking—thicker pieces stay rubbery. I learned this the hard way when my first batch turned out chewy; thin slices render faster and soak up the cheesy sauce better.
- SALT THE PASTA WATER: Toss the elbow macaroni in the boiling salted water for the first 2 minutes—yes, even if the recipe doesn’t say it. This guarantees the noodles absorb flavor before they hit the creamy sauce, and you’ll taste the difference.
- COMBINE CHEESES COLD: Grate the sharp cheddar and Monterey Jack fresh and mix them with the heavy cream while still cold—warm cheese clumps like glue. Stir in the sausage juices last to keep the sauce silky, not grainy.
- BAKE LOW AND COVERED: Start at 350°F with foil tented over the dish for the first 20 minutes—this locks in moisture so the top doesn’t dry out. After that, crank to 375°F and uncover for the final 10 minutes to get that golden crust. (Trust me, the first time I skipped this, the top was sad.)
Essential equipment for baked mac and cheese with sausage
Baking Dish Essentials
The right baking dish makes all the difference for that perfect crispy edge and even browning. I use a 9x13-inch heavy-duty baking dish—look for Ceramic or stainless steel options like CorningWare or All-Clad for even heat distribution.
Avoid thin aluminum dishes that can cause uneven cooking. Grease it well with butter or olive oil before adding the mac and cheese to prevent sticking. 🧈
Skillet for Sauce
A 10-inch cast iron skillet is my go-to for making the roux and cheese sauce—it retains heat beautifully and prevents scorching. If you don’t have cast iron, a heavy stainless steel skillet like All-Clad works just as well.
Avoid nonstick pans for the roux step; they don’t handle high heat as well. I keep my skillet on medium-low heat the whole time to avoid burning the flour.
Mixing Tools
You’ll need a wooden spoon for stirring the sauce (it won’t scratch your skillet) and a rubber spatula for scraping every last bit of cheese from the pot.
A hand mixer or immersion blender comes in handy if your sauce gets too thick—just blend for 10-15 seconds to smooth it out. For mixing the final dish, a large metal spatula helps distribute the breadcrumbs evenly.
Measuring Precisely
Accurate measurements are key, especially for the cheese and roux. Use a digital kitchen scale for the pasta and sausage—1.5 lbs elbow macaroni and 1 lb kielbasa should be exact. For the cheese, a box grater gives you the best texture.
A measuring cup set with clear markings ensures you don’t overdo the heavy cream or milk. Precision here keeps the sauce balanced and creamy. ✨
Oven Thermometer
Your oven’s temperature gauge can be off by 25°F or more, so I always use an oven thermometer to confirm it’s hitting 375°F. A Thermoworks Thermapen is my favorite—it’s fast and accurate.
If your oven runs hot, reduce the temperature by 10-15°F to avoid a burnt top. For even browning, place the dish on the middle rack where heat circulates best.

Frequently asked questions
Can I use ground sausage instead of kielbasa?
Ground sausage works wonderfully—just brown it thoroughly in the skillet before making the roux to render all the fat. For extra flavor, try Italian sausage with fennel seeds or spicy chorizo. The key is cooking it until crispy edges form, then mixing it into the cheese sauce for maximum flavor infusion.
Why did my mac and cheese turn out dry?
Dry mac and cheese usually means overbaking or not enough liquid in the sauce. Start by checking your baking time—20-25 minutes at 375°F is perfect. If it's still dry, try adding 2-3 tablespoons of milk or cream to the sauce before baking next time. Also, make sure your pasta is al dente before mixing.
How can I make this vegan?
Swap the butter for vegan butter, use heavy cream substitute (like coconut cream), and replace cheddar with vegan cheese like Miyoko's or Violife. For the sausage, try plant-based kielbasa or crumbled tofu seasoned with smoked paprika. The mustard powder adds tanginess that works well with vegan versions too!
Can I make this ahead of time?
Yes! Assemble the dish completely (including breadcrumbs) and refrigerate unbaked for up to 24 hours. When ready to bake, add 10-15 extra minutes to the cooking time. For meal prep, bake it fully, then store in airtight containers for 4-5 days. Reheat covered with foil at 350°F for 15-20 minutes.
What's the best way to reheat leftovers?
For the crispiest results, cover with foil and bake at 350°F for 15-20 minutes, then broil for 1-2 minutes to restore the crispy top. Microwaving works too—just add 1 tablespoon of milk to loosen the cheese, then heat in 30-second bursts while stirring between each.
