Cook pasta according to package directions. Drain.
Combine mayo and next 7 ingredients (through egg) in a large bowl; stir with a whisk. Gradually whisk in milk. Stir in cheese and pasta. Spoon into an 11 x 7-inch baking dish coated with cooking spray.
Combine oil and butter in a medium bowl. Add panko and parsley; toss. Sprinkle over pasta mixture. Bake at 350° for 30 minutes or until lightly browned.
I made this exactly how it was written with the exception of the cheese. I used what I already had on hand which was smoked/regular Gouda and mild Cheddar. I admit, after readying "mayo" as one of the ingredients I was kind of hesitant to even make because I do not like mayo at all, but I have to say it was pretty tasty. It had great flavor, was cheesy, but not to cheesy. We all had seconds. I will be making this again. :) Thank you!
I want to try this again because I didn't realize I was out of powdered mustard and substituted some French's mustard. That may have made this less than great in my family's opinion. My teenager considers herself a mac-n-cheese aficionado and she wasn't a fan of the smooth texture the mayo added. I'll try it once more before deciding whether or not to keep it in rotation.
Made this tonight and it was a hit. Except for using sharp cheddar and gouda cheese, 2 full cups combined, and 4 cups of cooked macaroni, everything else was as stated. The sauce was so creamy and flavorful. Husband was a happy guy. Always made mac and cheese with bechamel sauce but this sauce is amazing. Thanks for posting.
I made this recipe for the second time last night. Have to be honest that the use of mayo threw me initially, but it really just adds to the creamy texture. I think I would like it a bit creamier and might add more evaporated milk next time but otherwise, delish. Much easier and faster than making a sauce on the stove...
This was very tasty, especially the sauce and the topping, but was really not cheesy enough to be called "mac and cheese" in my book. I know you have to keep it light, but I'll probably add several ounces more cheese to it next time.
