Ingredients for baked macaroni and cheese with sausage

Sixteen ingredients for a one-pan casserole that delivers restaurant-quality comfort in under an hour.

Ingredient Amount Notes
Italian Sausage 🌭 1 ½ lb Kielbasa or spicy variety preferred
Elbow Macaroni 🍝 1 ½ cups Uncooked, standard size
Sharp Cheddar Cheese 🧀 2 cups Shredded, block preferred
Heavy Whipping Cream 🥛 ½ cup Full-fat for creaminess
Milk 🥛 ½ cup Whole milk preferred
Butter 🧈 3 tbsp Unsalted, room temperature
All-Purpose Flour 🌾 2 tbsp For roux thickening
Yellow Onion 🧅 1 whole Medium size, diced
Garlic Cloves 🧄 3 cloves Fresh, minced
Dried Mustard 🌶️ ½ tsp For depth of flavor
Salt 🧂 1 ½ tsp Kosher or sea salt
Black Pepper 🌶️ ½ tsp Freshly ground preferred
Panko Breadcrumbs 🍞 ½ cup For crispy topping
Parmesan Cheese 🧀 ¼ cup Freshly grated

The sausage sets the foundation—Italian kielbasa or spicy sausage delivers the best flavor, but any smoked sausage works. Costco or butcher shops often carry high-quality pre-cooked links, but check the ingredients for fillers. For the cheese, sharp cheddar is non-negotiable; pre-shredded contains anti-caking agents that prevent smooth melting. If you're using block cheese, grate it yourself for maximum creaminess. The onion and garlic should be fresh, with vibrant color and no soft spots—they're the aromatic base of the dish.

No sharp cheddar? Pepper jack or smoked cheddar add different but delicious depth. Running low on heavy cream? Half-and-half or whole milk will work, though the sauce may be slightly lighter. The panko topping can be swapped for crushed cornflakes if you're out, though it won't be as crispy. For a vegetarian version, replace the sausage with diced portobello mushrooms or crumbled tempeh. The mustard is key—Diamond Crystal is ideal, but any dry mustard will do. If you're short on time, pre-cooked sausage saves 10 minutes of active prep.

This casserole reheats beautifully—best served the next day when flavors meld. Store leftovers in an airtight container for up to 4 days in the fridge. For meal prep, portion into individual containers before baking—just pop them in the oven when ready. The breadcrumb topping can be made ahead of time and stored in the fridge for up to 3 days. Freezes well for up to 3 months—thaw overnight in the fridge before reheating. Serve with a simple arugula salad to cut through the richness.

Why You'll Love This Recipe

  • One-Pan Magic: I swear by this recipe because it’s the rare dish where you dump everything into one pan—no boiling pasta separately, no messy saucepans. The sausage browns while the pasta cooks in the same oven, and by the time the cheese melts into a golden crust, my kitchen looks cleaner than it did when I started.
  • Cheddar-Sausage Dream Team: That sharp cheddar and spiced Italian sausage? It’s a match made in comfort food heaven. The sausage adds smoky depth, while the cheese turns gooey and crispy in all the right ways—like a hug in a casserole dish.
  • Leftover Hero: Honestly, this dish tastes even better the next day. The flavors meld overnight, and reheating it is just about microwaving a bowl. I make a double batch on Sundays because it’s my go-to for lazy lunches or quick dinners when I’m not in the mood to cook.
  • Budget-Friendly Feast: A pound of sausage, a box of pasta, and a bag of cheese stretch to feed four for under $10. It’s my secret for stretching groceries without sacrificing flavor—plus, the kids (and my picky husband) always clear their plates. No sad leftovers here.

Step-by-step instructions for baked macaroni and cheese with sausage

A one-pan breakfast casserole that delivers rich, melty cheese and savory sausage in under an hour.

1

Brown the Sausage and Sauté Aromatics

Preheat your oven to 375°F. In a large oven-safe skillet, cook the 1.5 lb Italian sausage over medium-high heat until browned and cooked through, breaking it into small pieces. This should take about 8-10 minutes. The sausage should release easily from the pan when ready.

Once browned, reduce heat to medium and add 3 tbsp butter to the skillet. Toss in the diced yellow onion and cook for 5 minutes until softened. Add the minced garlic cloves and cook for another 30 seconds until fragrant. Remove the skillet from heat temporarily—we'll return to it after building the cheese sauce.

2

Create the Creamy Cheese Sauce

In a medium saucepan, melt 2 tbsp all-purpose flour with the remaining 1 tbsp butter over medium heat for 1 minute to create a roux. Slowly whisk in the 0.5 cup milk and 0.5 cup heavy whipping cream, cooking for 2-3 minutes until the mixture thickens slightly.

Reduce heat to low and stir in the 2 cups sharp cheddar cheese and 0.25 cup freshly grated parmesan cheese until completely melted and smooth. Remove from heat and stir in the 0.5 tsp dried mustard, 1.5 tsp salt, and 0.5 tsp black pepper. The sauce should be velvety and well-seasoned—this is where all the flavor comes together.

3

Assemble the Casserole

Return the skillet with sausage and aromatics to the stovetop over low heat. Add the 1.5 cups uncooked elbow macaroni and stir to coat with the rendered sausage fat. Pour the cheese sauce over the macaroni and sausage, stirring gently to combine. The mixture should look thick and creamy.

Transfer the skillet to the preheated 375°F oven. Bake for 25-30 minutes until the macaroni is tender and the top begins to bubble. The edges should be golden brown, and the cheese should be fully melted throughout. If the top browns too quickly, tent loosely with aluminum foil.

4

Add the Crispy Topping

Remove the casserole from the oven and sprinkle the 0.5 cup panko breadcrumbs evenly over the top. Return to the oven for an additional 5-7 minutes until the breadcrumbs are golden brown and crispy. This topping adds texture contrast and prevents the cheese from getting too soft.

Let the casserole rest for 5 minutes before serving. The internal temperature should reach 165°F at the center. Serve immediately with a side of roasted vegetables or a simple green salad. The combination of crispy sausage, creamy cheese, and tender macaroni makes this a satisfying breakfast or brunch dish that's ready in under an hour.

Pro Tips For Making Baked Macaroni And Cheese With Sausage

  • CRANK THE OVEN HIGH: Start the sausage and macaroni at 425°F—yes, even if you’re nervous about burning. The high heat renders fat fast and gets those edges golden before the cheese turns greasy. I used to bake it at 375°F and ended up with a sad, pale top every time.
  • GRILL THE SAUSAGE FIRST: Cut the sausage into ½-inch pieces and sear them in a dry skillet over medium-high heat until deeply browned—no need to add oil. The crispy edges add texture that just mixing them in won’t match. (And yes, this takes 5 minutes, but it’s worth it.)
  • TOAST THE PASTA DRY: Drain the cooked macaroni and spread it on a baking sheet for 2–3 minutes under the broiler. The extra starch caramelizes into a crispy crust instead of turning to glue. I learned this the hard way after my first batch turned into a single, sad lump.
  • STIR IN THE CREAM COLD: Whisk the heavy cream and milk into the cheese sauce off the heat—cold liquids temper the cheese and prevent curdling. If you pour it in hot, you’ll end up scraping gummy blobs off the bottom. (Your future self will thank you.)

Flavor customization for this recipe

Spicy Heat Boost

Swap out the mild Italian sausage for spicy kielbasa or add ½ tsp cayenne pepper to the cheese sauce for a kick. For extra heat, stir in 1 tbsp hot honey or 1 chopped jalapeño with the onions.

I love this with pepper jack cheese—it adds a subtle spicy tang that pairs perfectly with the sausage. 🌶️

Smoky BBQ Twist

Mix 2 tbsp BBQ sauce (like Sweet Baby Ray's) into the cheese sauce before combining with the pasta. Top with crumbled bacon and extra panko for a smoky, tangy variation that feels like a Southern brunch staple. For deeper flavor, use smoked cheddar instead of sharp cheddar.

Herb-Infused Freshness

Add 1 tbsp fresh thyme or rosemary to the sausage while browning, or stir chopped chives into the cheese sauce at the end. A sprinkle of fresh parsley on top adds brightness—especially great if you're serving this as a lighter lunch option.

I find fresh herbs elevate the dish without overpowering the cheesy, sausage flavors.

Extra Crispy Topping

For a crunchier crust, mix ½ cup panko with 2 tbsp melted butter and ¼ cup grated parmesan before sprinkling on top. Another trick? Toast 1 tbsp cornflakes separately for 30 seconds in a dry pan, then mix with the panko.

This adds a nutty crunch that contrasts beautifully with the creamy cheese. 🔥

Vegetable Add-Ins

Fold in ½ cup diced bell peppers or steamed broccoli when assembling the casserole for extra texture. Roasted zucchini or mushrooms work well too—just sauté them with the onions for even flavor distribution. I like adding sun-dried tomatoes for a pop of acidity that cuts through the richness.

Cheese Swaps

Replace sharp cheddar with Gruyère for a nutty depth, or mix in ½ cup gouda for a caramelized sweetness. For a lighter option, use part-skim mozzarella (but expect less meltiness).

I’ve also had great results with Monterey Jack—it’s milder but still creamy. Experiment with aged cheddar for a sharper bite.

Frequently asked questions

1

Can I use pre-cooked sausage instead of fresh?

Pre-cooked sausage saves time and works perfectly. Just crumble 1.5 lb of pre-cooked links (like kielbasa) directly into the skillet with the onions and garlic. Skip the browning step since it's already cooked through. This cuts 10 minutes off your prep time while keeping all the flavor.

2

How do I prevent the macaroni from getting mushy?

Use uncooked pasta and bake it in the oven—this ensures it cooks perfectly without over-softening. For extra insurance, boil the macaroni for 1 minute less than package instructions before baking. The residual starch helps bind the sauce, keeping the pasta al dente. Never skip the 5-minute rest before serving!

3

Can I make this ahead of time?

Yes! Assemble the casserole up to 24 hours ahead and refrigerate uncovered. When ready to bake, add the breadcrumb topping and bake at 375°F for 30-35 minutes (covered with foil for the first 20 minutes to prevent over-browning). The flavors actually improve overnight as the cheese melds. Perfect for meal prep!

4

What's the best way to reheat leftovers?

For best results, cover with foil and reheat at 350°F for 15-20 minutes until warmed through. The breadcrumb topping may soften slightly, but it's still delicious. For microwave reheating, use 50% power for 1-2 minutes, then cover with a damp paper towel to restore crispiness. Leftovers keep for 4 days in the fridge.

5

Why did my cheese sauce get grainy?

This usually happens when cheese is added too quickly or the sauce isn't hot enough. Always melt the cheese over low heat and stir constantly until completely smooth. For extra creaminess, whisk in 1 tbsp cold milk at the end to emulsify. Avoid pre-shredded cheese—it contains anti-caking agents that prevent proper melting.
