    Made this for a family reunion yesterday and it was a hit. My cousin said, “They loved your mac and cheese.” I topped it with crumbled bacon and it was delicious. This will be my go-to covered dish. Easy to prepare and serve.

    Super good! I ran out of cheddar cheese so used up my grated pepper jack, monterey jack and a tiny bit of Mexican whilte cheese. It was delecious with just a hint of pepper hot. My family loved it and so do I!!

  3. Added more cheese in sauce and on top. Yum. Used organic cheese and whole wheat noodles and a bit more butter. It was GREAT!! Thank u

  4. What type of milk would you recommend? Some recipes say evaporated is best, some say whole milk. I have 1% milk and evaporated can I mix them? And can I mix the cheeses? I have mozzarella and sharp cheddar, is that ok? I want to make today. Hoping I can get a quick response. Thanks!

        This was really good! I made a couple changes. Instead of sour cream, I used plain Greek yogurt. I also added panko breadcrumbs to the top. I kept it in the oven for about 45mins to make sure the whole thing was bubbly. Make sure to undercook your pasta because it will cook more in the sauce and soak up all the goodness.

    My secret ingredient for my mac n cheese is 4 Oz of Philadelphia Cream Cheese!
    Sour Cream is my secret ingredient for deviled eggs, to make the yoke mixture more creamy … I can’t wait to try your sour cream trick in my next mac n cheese!

    Made this many times now, everyone who has ever tried it says it’s the best they’ve ever had. Easy and sooooo good! In fact, just finished making it for thanksgiving brunch!

  7. Sour cream is a great secret ingredient in a lot of things, I have discovered…even scrambled eggs! Good find!

  8. When you say to turn the heat off, I am assuming you also need to let it cool some before you add the sour cream (not just turn the heat off and add sour cream, I would think it would still be too hot). Please let me know as I am thinking of making this tomorrow.

  9. Can this be made earlier in the day and then baked when needed? It will be great to make when my in-laws come for family Christmas, but I want it done ahead of time.

  10. Quick question….If the sour cream will curdle if the mixture is to hot when you first add it to the creamy mixture then will it curdle when you put it in the oven to bake it?

  11. No, it means 3 to 4 cups. Maybe 3, maybe 4, maybe in the middle. You be the judge.

    This recipe looks tasty! I’d probably add some sort of meat, just habit. I’m looking forward to trying it!

  12. Im confused of the amount of milk. Is it 3/4th cups of milk. Or 3..4 cups of milk. If thats the case that would be.. 12 cups?

  13. This is ONE of my secret weapons in my baked macaroni and cheese! I know this is good because it’s very close to mine!!

  14. Great recipe! Super easy to make, quick and tastes amazing! I added bread crumbs on the top to add a little crunch on top of everything! Thanks! 🙂
