This is the mac and cheese casserole that converts people. The secret? A hidden layer of cheese and sour cream in the middle that makes it ridiculously creamy without being complicated. It’s comfort food that actually feels special enough for company, but easy enough for a Tuesday.

It’s The Secret Center For Me.
If you grew up on boxed mac and cheese, same. I mean, I still make it every now and then for the nostalgia (and the ease, let’s be real).
But these days? I want real cheese and I want a lot of it.
Am I obsessed with our ultra creamy baked mac and cheese casserole. Yeah. Sure am.
It’s got that “how did you make this so good?” factor without requiring any fancy techniques or hard-to-find ingredients.
Intensely cheesy, ultra rich, super creamy, and just loaded with cheese.
With two layers of mac and cheese and a center layer of shredded cheese and sour cream, this is seriously the ULTIMATE mac and cheese recipe – which is why we’re calling it Million Dollar Mac and Cheese!

3 Reasons You’ll Love This Recipe
- Seriously creamy texture – That center layer of sour cream and extra cheese creates the creamiest mac and cheese you’ve ever had. No dry, disappointing bites here.
- Uses ingredients you probably have – Cheddar, milk, butter, sour cream. The Havarti and Gruyere are nice upgrades, but we’ve got swaps if you don’t have them.
- Reheats like a dream – Most mac and cheese turns sad and dry as leftovers. This one stays creamy and delicious, making it perfect for meal prep or bringing to potlucks.

Step by Step:
Cheese Sauce: First, you’ll make a roux, which is just a fancy term for melting some butter in a saucepan and stirring in some flour until it’s all combined.
Then you’ll whisk in some milk and heavy cream to make a thick sauce. Remove that from the heat and stir in the shredded cheddar cheese, salt, and pepper until it is smooth and creamy.
Combine: When the cheese sauce is ready, stir in your cooked macaroni and mix well to coat the pasta in all that glorious cheese!
Give it a taste and adjust the seasoning as needed. A bit more salt & pepper or a dash of hot sauce can go a long way.
Layer: Pour melted butter into the bottom of a 2 quart baking dish and then spoon half of the macaroni and cheese mixture into the dish.
Next spread the sour cream over the top of the macaroni and then sprinkle on the Havarti and gruyere cheeses! Top with the rest of the mac.
Topping: Since this is a baked mac and cheese, we’re going to top things off with a little Panko for some crunch.
Mix together the Panko, melted butter, garlic salt, and parsley to make the crunchy topping. Sprinkle it over the macaroni and cheese to add a little crunch to the finished dish.
Bake: Pop the dish into a preheated oven and bake for 25-30 minutes, or until the topping is as golden brown as you’d like.
Helpful Tip!
Cheese Sauce Tips & Tricks
- After adding your liquid to the roux, keep whisking and cooking over medium heat until it’s thickened. You’re going for the consistency of a thin gravy. It should coat the back of your spoon.
- Use blocks of cheese and grate them yourself. Pre-shredded cheese has added starches which doesn’t make for the creamiest cheese sauce.
- Remove your pan from the heat before you add the cheese. Cooking the cheese in the sauce can make for a grainy sauce.
Serving Ideas
As a main dish (serves 4-6): Pair with a simple green salad or roasted vegetables. Add some protein like rotisserie chicken if you want to make it heartier.
As a side dish (serves 8-10): Perfect for holidays, potlucks, or BBQs. Goes great with grilled meats, fried chicken, or as part of a comfort food spread.
For smaller households: You can easily halve this recipe or try freezing it for another day.
How to reheat mac and cheese:
I personally believe that not many macaroni and cheese recipes can hold up to reheating, but I’m here to tell you that this one reheats like a dream.
It doesn’t dry out. It doesn’t get funky in texture. It just stays perfectly creamy and decadent.
I reheat my macaroni and cheese in the microwave, because it’s easiest and it doesn’t dry things out.
Place in a microwave safe bowl and heat in 1 minute increments, stirring every minute, until it’s heated through.

Our family loves homemade Mac and cheese. Looking forward to making it for the next get together
Terri says
This sounds amazing. I would love to make and take to my mother in law.
Do you think I pre-make everything up until the baking part and travel for about 1 hour? Then bake it when I arrive at my location. I’m concerned about everything melting and pasta continuing to cook on the 1 hour trip.
Karly Campbell says
Hi Terri! I think this would be fine, but I haven’t tried that myself. I’m sure things will melt when you cover the dish, but that shouldn’t hurt anything.
Theresa says
This recipe is so good! Best Mac and cheese Iโve ever made.
Karly says
Love to hear that!
Sheri says
This was huge hit in my house!! I love all the different cheeses and so easy to make.
Karly says
Thanks, Sheri! So glad you enjoyed it!
Laura says
Hello I would like to know if you have a picture of the product that you used for the Panko bread itโs a lot options and I want to use the one that you used for this receipt thank you !
Karly says
Hi Laura! I’m not sure which one I used – we just use unseasoned panko from the store. They’re all the same. We get this brand quite a bit: https://amzn.to/3EsnKGg

Hi Karly: this dish sounds so delicious and I want to make it ! But the measurement totally confused me . It calls for 8 ounces of elbow macaroni which is not enough for how much of the other ingredients you would have to put in – and a box of it says that itโs 16 ounces – except if I put the elbow macaroni in a measuring cup a box measures out to more than 16 ounces ! So Iโm wondering – if I make it with a whole box of elbows ,how do I configure the other measurements ? Thanks if you can help ! CC
Karly says
Hello! The recipe is correct as written. 8 ounces of dry macaroni is accurate. It’s a very rich and cheesy dish.
Christina E Cooke says
I have this Mac and Cheese in the oven and it looks like a million dollars. Taking it to church today. I can’t wait to taste ?
Karly says
Hope you all love it, Christina!
Paula K says
Oh My, Ms.Karly!! This is similar to what I had as a kid. It was always a super special treat for us when Mom made Mac & Cheese.
I never had boxed mac & cheese before I moved to Arkansas! I also never had Velveeta which seems to be used a lot…personally I just don’t like it!
I never got the recipe from my Mom before she passed and this looks just like it. So I am super excited to try it. But please don’t be upset my Mom always put sliced fresh tomatoes on top of the bread crumbs with extra butter dotted around so I am going to do that everything else will be as you wrote it!!
I’m so excited to try this recipe that poor hubby (who’s sleeping right now) will be shocked when I tell him that I don’t want to go out to eat tomorrow and instead will be making this and a salad.
Karly says
Oh, I hope it’s close to your mom’s recipe! I believe Ina Garten uses bread crumbs and tomatoes on her mac & cheese too…it’s delicious! You might check her recipe if this isn’t close. ๐
Marlene Racine says
This recipe looks amazing, but do have one just like this for keto? I guess the only thing would be a substitute for the flour, I can use pork rinds for the panko and zucchini noodles for the macaroni. Thanks Karly
Karly says
Hi Marlene! I don’t have a keto version of this. We have a cauliflower mac and cheese that is delicious, but not super similar to this recipe. You can find that here: https://thatlowcarblife.com/cauliflower-mac-and-cheese/
