Tasty Roasted Garlic Mac and Cheese

Finding a mac and cheese recipe that goes beyond the basic boxed version but doesn’t require a culinary degree can feel impossible. You want something creamy and comforting that actually tastes like you put effort into it, but let’s be real – most of us don’t have hours to spend in the kitchen on a weeknight.

That’s where this roasted garlic mac and cheese comes in. It’s got that rich, homemade flavor you’re craving, but it’s straightforward enough to pull off on a busy evening, and the roasted garlic adds a depth of flavor that makes it feel special without any complicated steps.

What Kind of Cheese Should I Use?

For this mac and cheese, you’ll want to use a combination of cheeses to get the best flavor and texture. Sharp cheddar is the star here – it gives you that classic mac and cheese taste, and the sharper the better if you want more depth of flavor. The mozzarella adds creaminess and that satisfying cheese pull, while parmesan brings a nice salty, nutty finish. You can buy pre-shredded cheese if you’re short on time, but freshly grated cheese from a block melts much more smoothly since it doesn’t have the anti-caking agents that packaged shredded cheese contains. If you can’t find sharp cheddar, medium cheddar will work too, though the flavor won’t be quite as bold.

Options for Substitutions

This mac and cheese recipe is pretty forgiving when it comes to swaps:

• Elbow macaroni: Any short pasta works great here – try shells, cavatappi, penne, or rotini. They all hold onto that creamy cheese sauce nicely.
• Cheese blend: Feel free to mix up the cheese combo based on what you have. Gruyere, fontina, or gouda can replace some of the cheddar for different flavor profiles. Just keep the total amount around 5 cups of cheese.
• Sharp cheddar: Mild cheddar works if that’s what you have, though you’ll lose some of that tangy bite. You could also use white cheddar for a different look.
• Milk: Whole milk is best for creaminess, but 2% will work in a pinch. You can also use half-and-half for an extra rich sauce, though you might need slightly less.
• Breadcrumbs: Panko breadcrumbs give a crunchier topping, or you can use crushed crackers like Ritz for added flavor. Crushed cornflakes work too.
• Dijon mustard: Regular yellow mustard can substitute, though use a bit less as it’s milder. In a pinch, a tiny splash of white wine vinegar adds that tangy note.
• Roasted garlic: This is really the star of the dish, so I wouldn’t skip it. But if you’re short on time, you can use 2-3 teaspoons of garlic powder mixed into the sauce, though it won’t have quite the same sweet, mellow flavor.

Watch Out for These Mistakes While Cooking

The biggest mistake when making mac and cheese is adding cold milk to your roux, which can cause the sauce to seize up and become lumpy – always bring your milk to room temperature or warm it slightly before whisking it in gradually.

Overcooking your pasta is another common error that leads to mushy mac and cheese, so undercook your elbow macaroni by about 2 minutes since it will continue cooking in the oven and absorb more liquid from the cheese sauce.

When roasting the garlic, keep an eye on it after the 30-minute mark because burnt garlic turns bitter and can ruin the whole dish – you want it golden and soft, not dark brown.

Finally, resist the urge to skip the breadcrumb topping or add it too early, as sprinkling it on during the last 10-15 minutes of baking gives you that perfect golden, crispy crust without burning.

What to Serve With Roasted Garlic Mac and Cheese?

Since mac and cheese is pretty rich and indulgent, I like pairing it with something fresh and crisp to balance things out. A simple arugula or mixed greens salad with a tangy vinaigrette cuts through all that creamy cheese perfectly. If you want to add some protein to the meal, grilled chicken, pulled pork, or even some crispy bacon bits work great alongside or mixed right into the mac and cheese. For a full comfort food spread, roasted vegetables like broccoli, Brussels sprouts, or green beans make excellent sides that won’t leave you feeling too heavy.

Storage Instructions

Store: Keep your leftover mac and cheese in an airtight container in the fridge for up to 4 days. The cheese sauce might thicken up a bit as it sits, but that’s totally normal. I actually think it tastes even better the next day once all those roasted garlic flavors have had time to meld together!

Freeze: This mac and cheese freezes really well for up to 3 months. Let it cool completely, then portion it into freezer-safe containers or bags. I like to freeze individual servings so I can grab just what I need for a quick dinner.

Reheat: Warm it up in the oven at 350°F covered with foil until heated through, about 20-25 minutes from the fridge. You can also microwave individual portions, but add a splash of milk and stir halfway through to keep it creamy. If you want that crispy top again, pop it under the broiler for a minute or two at the end.

Ingredients

For the cheese sauce:

• 2 cups mozzarella cheese, shredded (adds creaminess and stretch)
• 2 cups sharp cheddar cheese, grated (freshly grated for better melting)
• 3 tbsp unsalted butter (I use Kerrygold for richness)
• 1 tbsp dijon mustard
• 4 cups milk (room temperature, prevents lumps)
• 1/2 cup parmesan cheese, grated
• 1 large head garlic (roasted until golden and caramelized)
• 3 tbsp all-purpose flour (creates a smooth roux base)
• Salt and black pepper to taste

For the pasta and assembly:

• Olive oil or cooking spray
• 14 oz elbow macaroni (or any short pasta shape)

For the topping:

• Fresh chives, finely chopped for garnish
• 1/2 cup parmesan cheese, grated (for extra savory crust)
• 1/2 cup breadcrumbs (I like panko for crispier texture)

Step 1: Roast the Garlic Until Golden and Caramelized

• 1 large head garlic
• Olive oil

Preheat your oven to 350°F.

Cut off the top quarter of a large garlic head to expose the cloves slightly, then place it on a small piece of foil.

Drizzle generously with olive oil and sprinkle with salt, then wrap the foil around it to create a sealed packet.

Roast for 45 to 60 minutes until the garlic is completely soft, golden, and caramelized—you’ll know it’s ready when it’s fragrant and easily squeezed out of its skin.

This long, slow roasting transforms raw garlic’s sharpness into something sweet and mellow, which is the backbone of this dish’s flavor.

Step 2: Cook the Pasta and Prepare a Roux-Based Cheese Sauce

• 14 oz elbow macaroni
• 3 tbsp unsalted butter
• 3 tbsp all-purpose flour
• 4 cups milk

While the garlic roasts, bring a large pot of salted water to a boil and cook the elbow macaroni according to package directions until al dente.

Before draining, reserve 1 cup of the starchy pasta water (this will help adjust the sauce consistency later), then drain the pasta and set aside.

In a separate saucepan, melt the butter over medium heat, then whisk in the flour to create a roux, stirring constantly for about 1 minute to cook out the raw flour taste.

Gradually whisk in the room-temperature milk slowly to avoid lumps, stirring frequently until the sauce thickens enough to coat the back of a spoon—this should take 5 to 7 minutes.

I like to use room-temperature milk rather than cold because it blends more smoothly into the roux without causing lumps.

Step 3: Build the Cheese Sauce with Roasted Garlic

• Roasted garlic from Step 1
• Sauce from Step 2
• 1 tbsp dijon mustard
• Salt and black pepper to taste
• 2 cups sharp cheddar cheese, grated
• 2 cups mozzarella cheese, shredded
• 1/2 cup parmesan cheese, grated

Once the roasted garlic has cooled slightly, squeeze all the soft cloves out of their skins into a small bowl and mash them together with a fork and a pinch of salt to create a smooth paste.

Stir the roasted garlic paste into the thickened sauce from Step 2, then add the Dijon mustard, and season with salt and pepper to taste.

Remove the pan from heat and add the grated sharp cheddar, shredded mozzarella, and 1/2 cup of grated parmesan, stirring gently until all the cheese is completely melted and the sauce is smooth and creamy.

The combination of three cheeses gives you sharp flavor from the cheddar, creaminess from the mozzarella, and a nutty depth from the parmesan.

Step 4: Combine Pasta with Cheese Sauce

• Cooked pasta from Step 2
• Cheese sauce from Step 3
• Reserved pasta water from Step 2
• Olive oil or cooking spray

Add the cooked pasta from Step 2 to the cheese sauce and fold gently until all the pasta is evenly coated.

If the mixture seems too thick, add a splash of the reserved pasta water and stir—the starch in the pasta water helps the sauce cling to the noodles while keeping it silky.

Transfer the mixture to a lightly oiled or cooking-spray-coated baking dish and spread it in an even layer.

Step 5: Create the Crispy Topping and Bake

• 1/2 cup parmesan cheese, grated
• 1/2 cup breadcrumbs
• Salt and black pepper to taste
• Olive oil or cooking spray

Increase the oven temperature to 390°F.

In a small bowl, combine the 1/2 cup of parmesan cheese with the breadcrumbs, a pinch of salt, and a crack of black pepper.

Sprinkle this mixture evenly over the mac and cheese, then lightly spray or drizzle with olive oil to help it crisp up in the oven.

I prefer panko breadcrumbs because they create a much crispier, more golden crust than regular breadcrumbs.

Bake for 20 to 25 minutes until the topping is golden brown and crispy and the sauce is bubbling around the edges.

Step 6: Garnish and Serve

• Fresh chives, finely chopped for garnish

Remove the baking dish from the oven and let it rest for 2 to 3 minutes so the sauce can set slightly.

Top with fresh, finely chopped chives for a bright color and subtle onion flavor that cuts through the richness of the cheese.

Serve warm and enjoy immediately.
