Ingredients for baked mac and cheese with sausage
Sixteen ingredients, one unforgettable casserole—crispy, cheesy, and packed with sausage goodness.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 1 ½ lbs | Dry, medium or jumbo size |
| Italian Sausage 🌭 | 1 ½ lbs | Sweet or spicy, casings removed |
| Unsalted Butter 🧈 | ¾ cup | Cold, cut into small cubes |
| All-Purpose Flour 🌾 | ½ cup | For roux, sifted if lumpy |
| Whole Milk 🥛 | 3 cups | Full-fat for creaminess |
| Shredded Sharp Cheddar Cheese 🧀 | 3 cups | Freshly grated preferred |
| Shredded Monterey Jack Cheese 🧀 | 1 ½ cups | For extra creaminess |
| Dry Breadcrumbs 🍞 | 1 cup | Panko for extra crispiness |
| Grated Parmesan Cheese 🧀 | ¼ cup | Freshly grated for topping |
| Garlic Powder 🧄 | 1 tbsp | For extra savory depth |
| Onion Powder 🧅 | 1 tbsp | Enhances sausage flavor |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Mustard Powder 🌶️ | ½ tsp | Brightens cheese flavor |
| Olive Oil 🫒 | 1 tbsp | For crispy topping |
The sausage is non-negotiable here—Italian sweet or spicy from Boar's Head or Johnsonville delivers that perfect balance of smoky depth. Look for packages labeled "all-beef" to avoid fillers. The cheese blend is where the magic happens: sharp cheddar for tang and Monterey Jack for creaminess. Kraft or Booth are solid grocery store options, but freshly grated always wins. For the breadcrumbs, Panko from Trader Joe's gives that perfect crispy texture—no need for fancy brands here, just make sure it's dry.
No Italian sausage? Kielbasa or smoked sausage works in a pinch, just slice it thin. Short on sharp cheddar? Pepper jack or Gouda add different but delicious flavors. The roux is key—don't rush the cooking or it'll taste raw. For extra richness, add a splash of heavy cream to the cheese sauce. The mustard powder might sound odd, but it cuts through the richness beautifully. If you're making this ahead, assemble the casserole but skip baking—it reheats beautifully the next day.
This casserole reheats like a dream—400°F for 20-25 minutes until bubbly and golden. Store leftovers in an airtight container for 4-5 days in the fridge, or freeze portions for up to 3 months. The breadcrumb topping loses crispiness when reheated, so bake fresh portions if serving later. For game day or parties, make it in a 9x13-inch baking dish—it feeds a crowd and looks impressive.

Step-by-step instructions for baked mac and cheese with sausage
Here's how to create that perfect crispy-topped, cheesy masterpiece with sausage.
🍳 Step 1: Cook the Sausage and Pasta
In a large skillet over medium heat, cook the 1.5 lbs Italian sausage until browned and fully cooked through, breaking it into small pieces as it cooks. This should take about 8-10 minutes. Remove the sausage from the skillet and set it aside.
In the same skillet, add the 1.5 lbs elbow macaroni and just enough water to coat the bottom. Cook for 2-3 minutes to soften slightly, then drain and return the pasta to the skillet. Remove from heat and set aside.
🍳 Step 2: Make the Ultimate Cheese Sauce
In a separate large pot, melt the 0.75 cup unsalted butter over medium heat. Once melted, whisk in the 0.5 cup all-purpose flour to create a roux. Cook for 1-2 minutes until bubbly but not browned.
Gradually whisk in the 3 cups whole milk, ensuring no lumps form. Add the 1.5 tsp salt, 0.5 tsp black pepper, 0.5 tsp mustard powder, 1 tbsp garlic powder, and 1 tbsp onion powder. Bring to a gentle simmer and cook for 3-4 minutes until slightly thickened.
Reduce heat to low and stir in the 3 cups shredded sharp cheddar cheese and 1.5 cups shredded Monterey Jack cheese until completely melted and smooth. The sauce should be rich, creamy, and just thick enough to coat the back of a spoon.
🥘 Step 3: Combine and Assemble
Add the cooked sausage and pasta to the cheese sauce, stirring gently to combine. Transfer the mixture to a 9x13-inch baking dish, spreading it evenly. The dish should be about ¾ full—this ensures the top will crisp properly.
In a small bowl, mix the 1 cup dry breadcrumbs, 0.25 cup grated Parmesan cheese, and 1 tbsp olive oil. Sprinkle this mixture evenly over the top of the mac and cheese, pressing down gently to ensure good coverage. This topping is what creates that coveted crispy crust.
🔥 Step 4: Bake to Golden Perfection
Preheat your oven to 375°F. Bake the mac and cheese for 25-30 minutes until the top is deep golden brown and the edges are bubbling. If the top browns too quickly, tent loosely with foil to prevent over-browning while the center finishes cooking.
You'll know it's done when the cheese is fully melted and the breadcrumb topping is crispy enough to hold its shape. The internal temperature should reach 165°F when checked with an instant-read thermometer.
⏰ Step 5: Rest and Serve
Remove the baking dish from the oven and let it rest for 5-10 minutes before serving. This resting period allows the cheese to set slightly, making it easier to serve without losing that perfect pull-apart texture.
Serve immediately with a side salad or crusty bread to soak up any extra cheese sauce. The combination of crispy topping, creamy cheese, and savory sausage makes this dish a true comfort food winner.
Pro Tips For Making Baked Mac And Cheese With Sausage
- CRACK THE SAUSAGE FIRST: I learned this the hard way—cooking the sausage after baking the mac and cheese means you’re left with dry, overcooked meat. Brown the sausage in a skillet first, then remove it to drain on paper towels while you make the roux. The fat renders out, and the sausage stays juicy when it goes back in later.
- DON’T SKIP THE WATER BOIL: Yes, elbow macaroni is forgiving, but if you rinse it after boiling, you’ll kill the starch that makes the cheese sauce cling. Drain it just before al dente, then toss it straight into the cheese sauce—no rinsing, no waiting. That starch is the glue holding your dish together.
- WHISK THE ROUX AGGRESSIVELY: I used to stir the butter and flour lazily, and my sauce always ended up lumpy. Crank the heat to medium-high and whisk like you mean it—no wooden spoons here. The goal is a smooth paste before the milk even hits, or you’ll be chasing lumps later. (And trust me, no one wants to fix that mid-bake.)
- BAKE IT COVERED THEN UNCOVERED: Cover the casserole with foil for the first 20 minutes—this keeps the top from drying out while the cheese melts. Then uncover and broil for 3-5 minutes at the end. That’s when the magic happens: the top turns golden and crispy, while the rest stays creamy. No foil? Your cheese will turn into a sad, gummy brick.
Storing and reheating this baked mac and cheese with sausage
Refrigerator Storage
Store leftovers in an airtight container for up to 4-5 days in the fridge. The breadcrumb topping loses crispiness when reheated, so I recommend baking fresh portions if serving later. Let the casserole cool completely before storing to prevent condensation from making the topping soggy. 🥫
Freezer Prep Tips
For longer storage, freeze portions in quart-sized freezer bags with 1 inch of headspace to prevent freezer burn. I like to portion into individual servings so you can thaw just what you need.
Label with the date—this mac and cheese stays delicious for up to 3 months in the freezer. Thaw overnight in the fridge before reheating. ❄️
Oven Reheating Method
My preferred way to reheat is in the oven at 400°F for 20-25 minutes until bubbly and golden. Cover loosely with foil if the top browns too quickly.
Add 1-2 tablespoons of milk to the breadcrumb topping before reheating to restore some crispiness. The internal temperature should reach 165°F for food safety. 🔥
Microwave Shortcut
For quick meals, use the microwave on 50% power for 2-3 minutes, stirring halfway. Add 1-2 tablespoons of water or milk to prevent drying. The texture won't be as crispy as oven-reheated, but it's perfect for lazy weeknights. Cover with a damp paper towel to retain moisture. 💫
Game Day Hack
Make this ahead and assemble the casserole in a 9x13-inch baking dish—it reheats beautifully for game day crowds. I like to bake it fresh before serving to guarantee that crispy topping. For extra crispiness, broil for 1-2 minutes at the end of reheating (watch closely!). 🏈
Make-Ahead Assembly
You can assemble the entire casserole (without baking) up to 24 hours ahead and refrigerate. When ready to bake, add 5-10 minutes to the baking time since it starts colder. This is my go-to strategy for busy days—just pop it in the oven when you're ready to eat. 📅
Nutrition facts
Frequently asked questions
Can I substitute ground beef for the sausage?
While ground beef works in a pinch, it won't provide the same flavor or texture. The sausage adds natural seasoning and fat that enhances the cheese sauce. If substituting, use 1.5 lbs ground beef and add 1 tsp Italian seasoning to mimic the sausage flavor. For best results, brown the beef thoroughly to remove excess fat.
Why did my mac and cheese get oily after baking?
This usually happens when the cheese sauce is too hot when mixed with the pasta, causing the cheese to separate. Always reduce heat to low when adding cheese and stir constantly. For extra insurance, whisk in 1 tablespoon cornstarch with the milk to help thicken the sauce properly.
Can I make this dish ahead of time?
Assemble the casserole completely (without baking) up to 24 hours ahead and refrigerate. When ready to bake, add 5-10 extra minutes to the baking time since it starts colder. For parties, this is a huge time-saver—just pop it in the oven when guests arrive.
What's the best way to get an extra crispy topping?
For maximum crispiness, use Panko breadcrumbs and add 1 tablespoon melted butter to the topping mix. After baking, broil for 1-2 minutes to create a golden crust. Press down firmly on the topping before baking to ensure even coverage and better browning.
How do I make this vegetarian?
Swap the sausage for 1.5 cups diced mushrooms or 1 cup crumbled tempeh for protein. For extra flavor, add 1 teaspoon smoked paprika to the cheese sauce. The mushrooms will absorb the cheese sauce beautifully, while tempeh adds a meaty texture. Adjust seasoning to taste.
