Ingredients for baked macaroni and cheese recipe with cream of mushroom soup

Six ingredients make this mushroom mac and cheese standout—no flour, no roux, just rich depth.

The cheeses are non-negotiable here. Sharp cheddar delivers that classic tang, while Gruyère brings nutty complexity—both need to be freshly shredded (pre-shredded gets gummy). I grab sharp cheddar from the deli counter (it melts better) and Gruyère from specialty stores like Whole Foods or Trader Joe's for that authentic flavor. The cream of mushroom soup? Campbell's or Progresso are solid choices, but if you want to level up, make your own mushroom reduction with wild mushrooms and vegetable broth. That said, the canned version works perfectly fine for weeknight dinners.

No panko? Crushed cornflakes or regular breadcrumbs work in a pinch, though panko gives that perfect crispy texture. Short on thyme? Dried thyme at one-third the amount gets you close, but fresh is ideal. The garlic can be roasted for a sweeter note—toss whole cloves with olive oil, roast at 400°F for 10 minutes, then mince. For a dairy-free twist, swap the heavy cream for full-fat coconut milk, though the texture will be slightly lighter. The butter topping is crucial—don't skip it! Use European-style butter if you have it for extra flavor.

This reheats beautifully—honestly tastes better the next day once everything melds together. Keeps for 4-5 days in the fridge, freezes for 3 months if you portion it into individual containers. For meal prep, assemble the dish in a baking dish, cover tightly with foil, and refrigerate. Bake straight from the fridge (just add 10 minutes) for foolproof results. Leftovers? Toss with a fried egg on top for a next-level breakfast.

Step-by-step instructions for creamy mushroom macaroni and cheese

Here's how to build a rich, savory baked mac and cheese with that perfect crispy topping.

Bring a large pot of water to a rolling boil and add 1.5 pounds of elbow macaroni. Season generously with 1 teaspoon of the kosher salt—it should taste like the ocean. Cook until al dente according to package instructions, which is typically 8-10 minutes for elbow macaroni. You want the pasta to be tender but still slightly firm to the bite.

Drain the pasta in a colander, but don't rinse it—those surface starches are crucial for binding the sauce. I like to give the pasta a quick shake to break up any clumps before moving to the next step. This ensures even distribution when we combine everything later.

In a large, oven-safe skillet, melt ½ cup of unsalted butter over medium heat. Add the 3 cloves minced garlic and sauté for 30 seconds until fragrant—you should smell that fresh garlic aroma wafting through your kitchen. Be careful not to let it brown, as that can make the flavor bitter.

Pour in the 2 cans of cream of mushroom soup and stir to combine. Let it simmer gently for 2 minutes to warm through. Then, gradually add the 3 cups sharp cheddar cheese and 1.5 cups Gruyère cheese while stirring constantly. The cheese should melt smoothly into a creamy sauce—if it looks too thick, add ¼ cup of the pasta water to loosen it.

Add the cooked elbow macaroni to the skillet and stir vigorously to coat every strand with the creamy mushroom cheese sauce. You want to make sure there are no dry spots of pasta. If the mixture seems too thick, add another ¼ cup of pasta water to achieve that perfect silky consistency.

Here's the thing—this is where the magic happens. The residual heat from the pasta will help the cheese melt completely and create that luscious, velvety texture we're after. Stir in the ½ cup heavy whipping cream and 1 tablespoon chopped fresh thyme leaves for that earthy aroma that ties everything together.

In a small bowl, combine the ½ cup panko breadcrumbs with the remaining ½ teaspoon kosher salt and ½ teaspoon freshly ground black pepper. Stir well to distribute the seasoning evenly. This topping is what transforms your mac and cheese from good to spectacular.

Spread the macaroni and cheese mixture evenly in the skillet, creating a flat surface. This helps the topping crisp up nicely rather than clumping in some areas. Sprinkle the seasoned panko breadcrumbs evenly over the top, pressing down gently with the back of a spoon to help them adhere.

Transfer the skillet to a preheated 375°F oven and bake for 20-25 minutes. You're looking for that beautiful golden-brown crust on top while keeping the cheese underneath creamy and bubbly. The edges should be slightly crispy, and the center should be hot but not burnt.

Here's a pro tip: If you notice the top browning too quickly, tent it loosely with aluminum foil for the last 5-10 minutes of baking. This prevents over-browning while still allowing the cheese to get nice and melty. Once it's done, let it rest for 5 minutes before serving—this helps the layers set and makes it easier to slice.

Pro cooking tips for perfect results

Sauce Thickness Secrets

The cream of mushroom soup is your secret weapon for a perfectly thick sauce without flour or roux. Start by warming the soup in the skillet with the butter and garlic, then gradually whisk in the cheeses.

If the mixture looks too thick, add ¼ cup pasta water one tablespoon at a time until it reaches a smooth, pourable consistency. I always test this by dipping a spoon in—it should coat the back smoothly but still flow off easily. 🥄

Cheese Melting Mastery

For ultra-smooth melted cheese, shred your own using a box grater or food processor with the shredding blade. Pre-shredded cheese contains anti-caking agents that make it gummy when melted. Add the cheeses gradually while stirring constantly over low heat—this prevents clumping.

If you're using Gruyère, grate it fresh and add it last since it melts slower than cheddar. The key is patience: let the cheese melt completely before combining with pasta.

Pasta Water is Gold

Never rinse your cooked pasta—those starchy waters are liquid gold for binding the sauce. Keep ½ cup pasta water reserved in a small bowl while you cook the pasta.

If your sauce seems too thick after combining, add the water 1 tablespoon at a time until you achieve that perfect velvety texture. Pro tip: The water should be hot when you add it to prevent the sauce from cooling too quickly.

This is especially important when using cream of mushroom soup, which can thicken more than traditional cheese sauces. 💡

Crispy Topping Hacks

For an extra-crispy crust, press the panko breadcrumbs firmly onto the top using the back of a spoon before baking. I like to mix in 1 tablespoon melted butter with the panko to help it brown more evenly.

If you're short on time, broil for the last 2-3 minutes of baking to get that deep golden color. For a nutty variation, mix in 2 tablespoons chopped walnuts with the panko—this adds texture and pairs beautifully with the mushroom flavors.

Baking Temperature Control

Bake at 375°F for even cooking, but watch closely after 15 minutes—this is when the top starts browning. If it's getting too dark too quickly, tent loosely with foil. The internal temperature should reach 160°F at the center.

I use an instant-read thermometer to check: insert it into the thickest part of the mac and cheese, avoiding the crispy top. The cheese should be fully melted but not rubbery. 🌡️

Resting for Perfect Slices

Never cut into your mac and cheese immediately after baking—let it rest for 5-10 minutes first. This allows the layers to set and prevents a runny mess. The resting time also helps the crispy topping firm up slightly, making it easier to slice cleanly.

For serving, use a long serrated knife and cut through the crispy top first, then the creamy center. This technique gives you perfectly shaped portions every time. Trust me, this small step makes all the difference! 🗡️
